Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Eine Insassenschutzvorrichtung für ein Fahrzeug umfasst mindestens einen einem Fahrzeugsitz zugeordneten Tisch. Insbesondere ist dieser Tisch, manuell und/oder elektrisch, insbesondere elektromotorisch, beispielsweise aus einer Verstauposition in eine Tischnutzungsposition bewegbar, in welcher er für einen auf dem Fahrzeugsitz sitzenden Insassen des Fahrzeugs verwendbar ist, und wieder zurück bewegbar. Der Tisch ist somit insbesondere im Bereich des Fahrzeugsitzes angeordnet, in der Verstauposition beispielsweise am oder im Fahrzeugsitz oder vor dem Fahrzeugsitz oder hinter dem Fahrzeugsitz oder seitlich neben dem Fahrzeugsitz oder unter dem Fahrzeugsitz oder über dem Fahrzeugsitz, und in der Tischnutzungsposition beispielsweise vor und/oder seitlich neben und/oder über dem Fahrzeugsitz, insbesondere vor und/oder seitlich neben dem Insassen im Fahrzeugsitz. Der Tisch ist beispielsweise als ein Klapptisch ausgebildet. Advantageous configurations of the invention are the subject matter of the dependent claims. An occupant protection device for a vehicle includes at least one table associated with a vehicle seat. In particular, this table can be moved manually and/or electrically, in particular by an electric motor, for example from a stowed position into a table use position, in which it can be used by an occupant of the vehicle sitting on the vehicle seat, and back again. The table is therefore arranged in particular in the area of the vehicle seat, in the stowed position, for example, on or in the vehicle seat or in front of the vehicle seat or behind the vehicle seat or to the side next to the vehicle seat or under the vehicle seat or above the vehicle seat, and in the table use position, for example in front of and/or laterally next to and/or above the vehicle seat, in particular in front of and/or laterally next to the occupant in the vehicle seat. The table is designed, for example, as a folding table.

Erfindungsgemäß ist dieser mindestens eine Tisch, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision und/oder Kollisionsgefahr des Fahrzeugs, insbesondere aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in mindestens eine Insassenschutzposition bewegbar, in der er zumindest einen Körperabschnitt, insbesondere einen Oberkörper, eines Insassen gegen eine kollisionsbedingte Verlagerung abstützt und/oder eine Abstützfläche für mindestens einen sich aus einem anderen Fahrzeugteil, d. h. nicht aus dem Tisch, entfaltenden Airbag bildet. Diese Abstützfläche ist insbesondere zum Lenken, Führen und/oder Stützen des Airbags während dessen Entfaltung und/oder insbesondere zum Abstützen des entfalteten Airbags vorgesehen. According to the invention, this at least one table, in particular from the table use position and/or from the stowed position, is in particular active, i. H. driven, in particular electrically, in particular by an electric motor, and/or pneumatically and/or hydraulically and/or pyrotechnically, in particular automatically, into at least one occupant protection position, in which it supports at least one body section, in particular an upper body, of an occupant against displacement caused by a collision and/or a support surface for at least one part that extends from another vehicle part, d. H. not from the table, inflating airbag forms. This support surface is provided in particular for directing, guiding and/or supporting the airbag during its deployment and/or in particular for supporting the deployed airbag.

Ein erfindungsgemäßes Fahrzeug umfasst eine solche Insassenschutzvorrichtung. Beispielsweise kann die Insassenschutzvorrichtung mehrere solche Tische aufweisen, beispielsweise ist mehreren oder allen Fahrzeugsitzen des Fahrzeugs jeweils ein solcher Tisch zugeordnet, beispielsweise zumindest Rücksitzen und/oder einem Beifahrersitz. A vehicle according to the invention includes such an occupant protection device. For example, the occupant protection device can have several such tables, for example one such table is assigned to several or all vehicle seats of the vehicle, for example at least rear seats and/or a passenger seat.

In einem erfindungsgemäßen Verfahren zum Betrieb der Insassenschutzvorrichtung wird der mindestens eine Tisch, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision oder Kollisionsgefahr des Fahrzeugs aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in eine Insassenschutzposition bewegt, in der er zumindest einen Körperabschnitt, insbesondere einen Oberkörper, eines Insassen gegen eine kollisionsbedingte Verlagerung abstützt und/oder eine Abstützfläche für mindestens einen sich aus einem anderen Fahrzeugteil, d. h. nicht aus dem Tisch, entfaltenden Airbag bildet. Diese Abstützfläche ist insbesondere zum Lenken, Führen und/oder Stützen des Airbags während dessen Entfaltung und/oder insbesondere zum Abstützen des entfalteten Airbags vorgesehen. In a method according to the invention for operating the occupant protection device, the at least one table becomes active, in particular from the table use position and/or from the stowed position, when a collision or risk of collision of the vehicle is detected, i.e. in particular electrically, in particular by an electric motor, and/or pneumatically and/or hydraulically and/or pyrotechnically driven, in particular automatically, in moves an occupant protection position in which it supports at least one body section, in particular an upper body, of an occupant against displacement caused by a collision and/or forms a support surface for at least one airbag unfolding from another part of the vehicle, ie not from the table. This support surface is provided in particular for directing, guiding and/or supporting the airbag during its deployment and/or in particular for supporting the deployed airbag.

Der elektrische, insbesondere elektromotorische, und/oder pneumatische und/oder hydraulische Antrieb ermöglicht insbesondere eine reversible Bewegung des Tischs. Dies ist insbesondere vorteilhaft bei einer erkannten Kollisionsgefahr, wobei noch die Möglichkeit besteht, die Kollision zu verhindern. Die pyrotechnische Bewegung ist besonders schnell und dadurch insbesondere für eine erkannte bereits erfolgende Kollision des Fahrzeugs geeignet. The electrical, in particular electromotive, and/or pneumatic and/or hydraulic drive enables, in particular, a reversible movement of the table. This is particularly advantageous when a risk of collision is detected, it still being possible to prevent the collision. The pyrotechnic movement is particularly fast and is therefore particularly suitable for a recognized collision of the vehicle that is already taking place.

Der Tisch umfasst beispielsweise mindestens eine Eingabeeinheit und/oder mindestens eine Anzeigeeinheit und/oder mindestens eine akustische Ausgabeeinheit. Die Eingabeeinheit ist beispielsweise eine Tastatur, ein taktiles Display oder eine Projektion mit Gestikerkennung. The table comprises, for example, at least one input unit and/or at least one display unit and/or at least one acoustic output unit. The input unit is, for example, a keyboard, a tactile display or a projection with gesture recognition.

Durch die beschriebene Lösung wird ein Tisch, welcher vom Insassen beispielsweise als Arbeitstisch und/oder Ablagefläche und/oder Eingabe- und/oder Ausgabeeinheit, beispielweise als Tastatur und/oder Bedieneinheit, genutzt werden kann, bei einer erkannten Kollision oder Kollisionsgefahr optimiert positioniert, um den Insassen zu schützen. Die Insassenschutzposition, in der der Tisch zumindest einen Körperabschnitt, insbesondere den Oberkörper, des Insassen gegen die kollisionsbedingte Verlagerung abstützt, ist beispielsweise eine Position an einer Vorderseite des Insassen, insbesondere an einer Vorderseite des Oberkörpers des Insassen, insbesondere an dessen Brust, d. h. der Tisch wird entsprechend an den Insassen, insbesondere an dessen Oberkörper, insbesondere an dessen Brust, heranbewegt, insbesondere an diesem anliegend positioniert. Dadurch ist der Insasse, insbesondere dessen Oberkörper, vorteilhafterweise vorderseitig durch den Tisch und rückseitig durch eine Sitzlehne des Fahrzeugsitzes abgestützt und wird entsprechend gehalten. Durch dieses Positionieren des Tischs vor dem Oberkörper, insbesondere vor der Brust, wird eine flächige Rückhaltung des Insassen ermöglicht, wodurch eine Last auf dem Brustkorb des Insassen reduziert wird. Durch die beschriebene Lösung werden somit Tätigkeiten, insbesondere Nebentätigkeiten, insbesondere solche, die eine Eingabeeinheit erfordern, ohne eine Reduzierung der Insassensicherheit und Fahrsicherheit ermöglicht. With the solution described, a table, which the occupant can use, for example, as a work table and/or shelf and/or input and/or output unit, for example as a keyboard and/or operating unit, is optimally positioned when a collision or risk of a collision is detected to protect the occupant. The occupant protection position, in which the table supports at least a part of the occupant's body, in particular the upper body, of the occupant against the displacement caused by the collision, is, for example, a position on a front side of the occupant, in particular on a front side of the upper body of the occupant, in particular on his chest, ie the table is accordingly moved up to the occupant, in particular to his upper body, in particular to his chest, in particular positioned so that it rests against it. As a result, the occupant, in particular his upper body, is advantageously supported at the front by the table and at the rear by a backrest of the vehicle seat and is held accordingly. This positioning of the table in front of the upper body, in particular in front of the chest, enables the occupant to be restrained over a large area, thereby reducing the load on the occupant's chest. The solution described thus enables activities, in particular secondary activities, in particular those that require an input unit, without reducing passenger safety and driving safety.

Insbesondere umfasst die Insassenschutzvorrichtung auch den mindestens einen Airbag. Dadurch wird eine aufeinander optimierte Funktion des Tischs und des Airbags ermöglicht. Der mindestens eine Airbag kann beispielsweise in einer Instrumententafel, einem Armaturenbrett und/oder einem Cockpit des Fahrzeugs angeordnet sein und sich daraus entfalten, oder in einem Sicherheitsgurt angeordnet sein und sich daraus entfalten, oder im Fahrzeugsitz, beispielsweise seitlich in einem Sitzkissen oder in einer Sitzlehne oder in einer Armstütze, angeordnet sein und sich daraus entfalten, oder in einer Mittelkonsole des Fahrzeugs angeordnet sein und sich daraus entfalten, oder in einer Innenraumverkleidung, beispielsweise Seitenverkleidung oder Dachverkleidung, des Fahrzeugs angeordnet sein und sich daraus entfalten. Es können auch mehrere in verschiedenen dieser Fahrzeugteile und somit an verschiedenen Positionen im Fahrzeug angeordnete Airbags vorgesehen sein, welche, insbesondere je nach vorliegenden Gegebenheiten bei der erkannten Kollision oder Kollisionsgefahr, entfaltet werden und vom Tisch in seiner entsprechenden Insassenschutzposition abgestützt werden. In particular, the occupant protection device also includes the at least one airbag. This enables the table and the airbag to work in a way that is optimized for each other. The at least one airbag may be located in and deploy from an instrument panel, dashboard and/or cockpit of the vehicle, for example, or located in and deploy from a seat belt, or in the vehicle seat, for example in a side seat cushion or seat back or in an armrest, and unfolding therefrom, or in a center console of the vehicle and unfolding therefrom, or in an interior panel, such as side panels or headlining, of the vehicle and unfolding. It is also possible to provide several airbags arranged in various of these vehicle parts and thus at various positions in the vehicle, which are deployed and supported by the table in its corresponding occupant protection position, particularly depending on the prevailing circumstances when a collision or risk of collision is detected.

Die Insassenschutzposition, in welche der Tisch bei einer erkannten Kollision oder Kollisionsgefahr bewegbar ist bzw. bewegt wird, ist beispielsweise abhängig von einer Art der erkannten Kollision oder Kollisionsgefahr, zum Beispiel Front-, Seiten- oder Heckkollision oder Gefahr hierfür, und/oder von einer Sitzposition des Insassen, und/oder von einer Sitzeinstellung des Fahrzeugsitzes, und/oder von einem Anlegezustand eines dem Fahrzeugsitz zugeordneten Sicherheitsgurtes, d. h. ob dieser vom Insassen ordnungsgemäß angelegt ist oder nicht, insbesondere ob ein Gurtschloss geschlossen ist oder nicht, und/oder von einer Ausrichtung des Insassen und/oder des Fahrzeugsitzes relativ zu dem mindestens einen abzustützenden Airbag. Dadurch wird eine auf diese jeweils vorliegenden Gegebenheiten optimierte Insassenschutzposition für den Tisch ermöglicht, in welche der Tisch dann bewegbar ist bzw. bewegt wird. The occupant protection position into which the table can be moved or is moved when a collision or risk of a collision is detected depends, for example, on the type of collision or risk of collision detected, for example a front, side or rear collision or the risk thereof, and/or on a Seating position of the occupant, and/or a seat adjustment of the vehicle seat, and/or an application state of a safety belt assigned to the vehicle seat, d. H. whether this is properly put on by the occupant or not, in particular whether a seat belt buckle is closed or not, and/or an orientation of the occupant and/or the vehicle seat relative to the at least one airbag to be supported. This enables an occupant protection position for the table that is optimized for these particular circumstances, into which the table can then be moved or is moved.

Der Tisch ist zur aktiven Bewegung in die Insassenschutzposition insbesondere um mindestens eine Drehachse, beispielsweise um mehrere Drehachsen, drehbar und/oder um mindestens eine Achse, beispielsweise um mehrere Achsen, schwenkbar und/oder entlang mindestens einer Achse, beispielsweise entlang mehrerer Achsen, verschiebbar. Vorteilhafterweise ist eine Kombination mehrerer dieser Bewegungsmöglichkeiten oder aller genannten Bewegungsmöglichkeiten vorgesehen, um den Tisch in eine Vielzahl möglicher Insassenschutzpositionen bewegen zu können. Dadurch wird eine auf die bei erkannter Kollision oder Kollisionsgefahr jeweils vorliegenden Gegebenheiten optimierte Insassenschutzposition und die Bewegung des Tisches in diese Insassenschutzposition ermöglicht. For active movement into the occupant protection position, the table can be rotated about at least one axis of rotation, for example about several axes of rotation, and/or can be pivoted about at least one axis, for example about several axes, and/or can be displaced along at least one axis, for example along several axes. Advantageously, a combination of several of these movement options or all of the movement options mentioned is provided in order to divide the table into a plurality to be able to move possible occupant protection positions. This enables an occupant protection position that is optimized for the circumstances that are present when a collision or risk of a collision is detected, and the movement of the table into this occupant protection position.

In einer möglichen Ausführungsform ist der Tisch mit der Mittelkonsole des Fahrzeugs gekoppelt. Dadurch wird eine sichere Verankerung des Tischs im Fahrzeug sichergestellt, es wird eine Verstauung des Tischs in der Verstauposition auf einfache Weise ermöglicht, es wird eine optimierte Tischnutzungsposition für den Tisch ermöglicht und es werden insbesondere eine Vielzahl möglicher Insassenschutzpositionen für den Tisch ermöglicht, in welche der Tisch dann je nach bei erkannter Kollision oder Kollisionsgefahr jeweils vorliegenden Gegebenheiten bewegt werden kann. In one possible embodiment, the table is coupled to the center console of the vehicle. This ensures that the table is securely anchored in the vehicle, the table can be easily stowed away in the stowage position, an optimized table usage position is made possible for the table and, in particular, a large number of possible occupant protection positions are made possible for the table, into which the The table can then be moved depending on the circumstances present when a collision or risk of collision is detected.

In einer möglichen Ausführungsform weist der Tisch mindestens ein aufblasbares Schutzsystem auf, welches insbesondere als ein Tischairbag ausgebildet ist und daher im Folgenden als Tischairbag bezeichnet wird. Der Tischairbag ist bei der erkannten Kollision oder Kollisionsgefahr des Fahrzeugs, insbesondere durch Aktivieren, insbesondere Zünden, mindestens eines Gasgenerators entfaltbar. Beispielsweise kann der Tisch auch mehrere solche Tischairbags aufweisen, zum Beispiel einen Tischairbag, welcher sich an einer Oberseite des Tischs entfaltet, und einen weiteren Tischairbag, welcher sich an einer Unterseite des Tischs entfaltet und dann beispielsweise als Knieairbag zum Schutz von Becken und/oder Beinen, insbesondere Oberschenkeln und/oder Knien, des Insassen dient. Durch das Bewegen des Tischs in die Insassenschutzposition wird eine optimierte Ausrichtung dieses mindestens einen oder jeweiligen Tischairbags ermöglicht. Es kann beispielsweise vorgesehen sein, dass der Tisch, insbesondere die mindestens eine Eingabeeinheit, Ausgabeeinheit und/oder Anzeigeeinheit, mit einer Öffnung, beispielsweise einer Reißklappe wie bei Airbags oder mechanisch und/oder elektrisch freischaltbar, versehen ist, durch die sich der Tischairbag entfalten kann, insbesondere in Richtung des Insassen, nach oben oder nach unten, nach unten insbesondere bei entsprechend positioniertem Tisch. In one possible embodiment, the table has at least one inflatable protection system, which is designed in particular as a table airbag and is therefore referred to below as a table airbag. The table airbag can be deployed when a collision or risk of collision of the vehicle is detected, in particular by activating, in particular igniting, at least one gas generator. For example, the table can also have several such table airbags, for example a table airbag, which unfolds on an upper side of the table, and another table airbag, which unfolds on an underside of the table and then, for example, as a knee airbag to protect the pelvis and/or legs , In particular thighs and / or knees, the occupant is used. By moving the table into the occupant protection position, an optimized alignment of this at least one or respective table airbag is made possible. It can be provided, for example, that the table, in particular the at least one input unit, output unit and/or display unit, is provided with an opening, for example a tear flap as in airbags or which can be released mechanically and/or electrically, through which the table airbag can unfold , in particular in the direction of the occupant, upwards or downwards, downwards in particular with a correspondingly positioned table.

Beispielsweise kann auch nur ein Tischairbag vorgesehen sein, welcher dann durch das Bewegen des Tischs in die an die jeweils vorliegenden Gegebenheiten angepasste Insassenschutzposition entsprechend ausgerichtet wird. Beispielsweise kann dann, je nach vorliegenden Gegebenheiten bei erkannter Kollision oder Kollisionsgefahr, vorgesehen sein, dass sich dieser Tischairbag an einer eine Oberseite des Tischs bildenden Fläche entfaltet, zum Beispiel nach oben und/oder in Richtung des Insassen, um einen Oberkörper und/oder Kopf des Insassen zu schützen, oder durch ein entsprechendes Bewegen, insbesondere Drehen, des Tischs, an einer dann eine Unterseite des Tischs bildenden Fläche entfaltet, um das Becken und/oder die Beine, insbesondere Oberschenkel und/oder Knie, des Insassen zu schützen. Auf diese Weise kann der Tisch, wenn bei der erkannten Kollision oder Kollisionsgefahr eine erhöhte Kniebelastung erwartet wird, insbesondere ohne den Oberkörper besonders zusätzlich schützen zu müssen, der Tisch in eine derartige Insassenschutzposition bewegt werden, insbesondere gedreht werden, dass der Tischairbag dann als Knieairbag, auch als „Knee-Bag“ bezeichnet, dient. Beispielsweise kann dabei gleichzeitig eine dann freie Oberseite des Tischs die Abstützfläche für den mindestens einen sich aus dem anderen Fahrzeugteil entfaltenden Airbag bilden, wodurch gleichzeitig der Kopf und/oder Oberkörper des Insassen geschützt ist, falls dieser Schutz erforderlich ist. For example, only one table airbag can be provided, which is then aligned accordingly by moving the table into the occupant protection position adapted to the prevailing circumstances. For example, depending on the prevailing circumstances when a collision or risk of collision is recognized, it can be provided that this table airbag unfolds on a surface forming an upper side of the table, for example upwards and/or in the direction of the occupant, to protect an upper body and/or head of the occupant, or by correspondingly moving, in particular rotating, the table on a surface then forming an underside of the table unfolds around the pelvis and/or the legs, in particular thighs and/or knees to protect the occupant. In this way, if an increased knee load is expected when a collision or risk of a collision is detected, the table can be moved, in particular rotated, into such an occupant protection position that the table airbag then acts as a knee airbag, in particular without having to additionally protect the upper body. also known as a "knee bag". For example, an upper side of the table that is then free can simultaneously form the support surface for the at least one airbag unfolding from the other part of the vehicle, whereby the head and/or upper body of the occupant is protected at the same time, if this protection is required.

Die Insassenschutzvorrichtung umfasst beispielsweise eine Kollisionssensorik zur Erkennung einer Kollision und/oder Kollisionsgefahr, insbesondere auch zur Erkennung der Art der Kollision oder Kollisionsgefahr, zum Beispiel Front-, Seiten- oder Heckkollision oder Gefahr hierfür, und/oder eine Insassenpositionssensorik zur Erkennung einer Sitzposition des Insassen, und/oder eine Sitzeinstellungssensorik zur Erkennung einer Sitzeinstellung des Fahrzeugsitzes und/oder eine Ausrichtungssensorik zur Erkennung einer Ausrichtung des Insassen und/oder des Fahrzeugsitzes relativ zu dem mindestens einen abzustützenden Airbag. The occupant protection device includes, for example, a collision sensor system for detecting a collision and/or the risk of a collision, in particular also for detecting the type of collision or the risk of a collision, for example a front, side or rear collision or the risk thereof, and/or an occupant position sensor system for detecting a seating position of the occupant , and/or a seat setting sensor for detecting a seat setting of the vehicle seat and/or an orientation sensor for detecting an orientation of the occupant and/or the vehicle seat relative to the at least one airbag to be supported.

Die Kollisionssensorik kann beispielsweise mindestens einen Kamerasensor, Lidarsensor, Ultraschallsensor, Radarsensor, Kraftsensor, Verformungssensor, Bewegungssensor und/oder Beschleunigungssensor aufweisen. Es können auch vom jeweiligen Sensortyp mehrere Sensoren vorgesehen sein. Kamerasensor, Lidarsensor, Ultraschallsensor und/oder Radarsensor sind dabei insbesondere Bestandteil einer Umfelderfassungssensorik zur Erfassung eines äußeren Umfeldes des Fahrzeugs. The collision sensor system can have, for example, at least one camera sensor, lidar sensor, ultrasonic sensor, radar sensor, force sensor, deformation sensor, motion sensor and/or acceleration sensor. Several sensors can also be provided for the respective sensor type. Camera sensor, lidar sensor, ultrasonic sensor and/or radar sensor are particularly part of an environment detection sensor system for detecting an external environment of the vehicle.

Die Insassenpositionssensorik kann beispielsweise mindestens einen Kamerasensor, Lidarsensor, Ultraschallsensor, Radarsensor, Kraftsensor, Verformungssensor, Bewegungssensor, Beschleunigungssensor, Gewichtssensor, Kontaktsensor, insbesondere Körperkontaktsensor, und/oder Sicherheitsgurtsensor aufweisen. Diese Sensoren sind insbesondere Bestandteil einer Innenraumüberwachung des Fahrzeugs.The occupant position sensor system can have, for example, at least one camera sensor, lidar sensor, ultrasonic sensor, radar sensor, force sensor, deformation sensor, movement sensor, acceleration sensor, weight sensor, contact sensor, in particular body contact sensor, and/or seat belt sensor. In particular, these sensors are part of an interior monitoring system for the vehicle.

Es können auch vom jeweiligen Sensortyp mehrere Sensoren vorgesehen sein. Der jeweilige mindestens eine Kraftsensor, Verformungssensor, Bewegungssensor, Beschleunigungssensor, Gewichtssensor und/oder Kontaktsensor, insbesondere Körperkontaktsensor, kann beispielsweise am oder im Fahrzeugsitz angeordnet sein, zum Beispiel als Bestandteil einer Sitzbelegungserkennung. Der mindestens eine Sicherheitsgurtsensor dient insbesondere der Erfassung des Anlegezustands des dem Fahrzeugsitz zugeordneten Sicherheitsgurtes, d. h. ob der Insasse diesen ordnungsgemäß angelegt hat oder nicht, insbesondere ob ein Gurtschloss geschlossen ist oder nicht. Beispielsweise ist dieser Sicherheitsgurtsensor im Gurtschloss angeordnet. Der mindestens eine Kontaktsensor kann beispielsweise in einem Lenkrad oder am oder im Tisch angeordnet sein. Der jeweilige mindestens eine Kamerasensor, Lidarsensor, Ultraschallsensor und/oder Radarsensor ist insbesondere derart im Fahrzeug angeordnet, dass sein Erfassungsbereich den Fahrzeugsitz und den Insassen, wenn ein solcher darin sitzt, umfasst, insbesondere in jeder möglichen Sitzposition, Sitzeinstellung und Ausrichtung. Several sensors can also be provided for the respective sensor type. The respective at least one force sensor, deformation sensor, movement sensor, acceleration sensor, weight sensor and/or contact sensor, in particular Body contact sensor can be arranged, for example, on or in the vehicle seat, for example as part of a seat occupancy detection. The at least one seat belt sensor is used in particular to detect the wearing state of the seat belt assigned to the vehicle seat, ie whether the occupant has put it on properly or not, in particular whether a seat belt buckle is closed or not. For example, this seat belt sensor is arranged in the seat belt buckle. The at least one contact sensor can be arranged, for example, in a steering wheel or on or in a table. The respective at least one camera sensor, lidar sensor, ultrasonic sensor and/or radar sensor is arranged in the vehicle in particular in such a way that its detection range encompasses the vehicle seat and the occupant if one is seated therein, in particular in every possible seat position, seat setting and orientation.

Die Sitzeinstellungssensorik kann beispielsweise mindestens einen Sensor oder mehrere Sensoren im Fahrzeugsitz, insbesondere in dessen Verstellmechanismus, umfassen, wobei diese Sitzeinstellungssensorik auch durch den Verstellmechanismus selbst gebildet sein kann. The seat adjustment sensor system can, for example, comprise at least one sensor or several sensors in the vehicle seat, in particular in its adjustment mechanism, and this seat adjustment sensor system can also be formed by the adjustment mechanism itself.

Die Ausrichtungssensorik kann teilweise oder vollständig identisch sein mit der Insassenpositionssensorik und/oder der Sitzeinstellungssensorik, d. h. einen oder mehrere oder alle der dort genannten Sensoren nutzen oder die gleichen Sensoren aufweisen. Auf diese Weise wird eine entsprechend der jeweils vorliegenden Gegebenheiten optimierte Insassenschutzposition für den Tisch ermöglicht. The orientation sensor system can be partially or completely identical to the occupant position sensor system and/or the seat adjustment sensor system, i. H. use one or more or all of the sensors mentioned there or have the same sensors. In this way, an occupant protection position for the table that is optimized according to the prevailing conditions is made possible.

Durch die beschriebene Lösung wird es beispielsweise ermöglicht, je nach vorliegenden Gegebenheiten bei einer erkannten Kollision oder Kollisionsgefahr beispielsweise den Tischairbag zu entfalten, wobei der Tisch in die entsprechend optimierte Insassenschutzposition bewegt wird, um den Tischairbag optimal zu positionieren. Beispielsweise wird der Tisch bei einer erwarteten erhöhten Kniebelastung, insbesondere ohne den Oberkörper besonders zusätzlich schützen zu müssen, derart bewegt, insbesondere gedreht, dass der Tischairbag als Knieairbag dient. The solution described makes it possible, for example, to unfold the table airbag depending on the prevailing circumstances when a collision or risk of collision is detected, with the table being moved into the correspondingly optimized occupant protection position in order to optimally position the table airbag. For example, when an increased knee load is expected, the table is moved, in particular rotated, in such a way that the table airbag serves as a knee airbag, in particular without having to additionally protect the upper body.

Alternativ kann beispielsweise je nach vorliegenden Gegebenheiten, zum Beispiel wenn der Insasse sich aufgrund einer entsprechenden Sitzeinstellung in einer so genannten Relaxed-Position, d. h. in einer entspannten Sitzposition, befindet, d. h. beispielsweise mit stark nach hinten geneigtem und beispielsweise zusätzlich nach hinten verschobenem Fahrzeugsitz erkannt werden, dass Airbags in anderen Fahrzeugteilen den Insassen nicht erreichen können, so dass der Tisch in eine derartige Insassenschutzposition bewegt wird, dass er zumindest einen Körperabschnitt, insbesondere den Oberkörper, des Insassen gegen eine kollisionsbedingte Verlagerung abstützt. Auch hier kann beispielsweise zusätzlich der Tischairbag entfaltet werden, insbesondere in Richtung des Insassen, um einen harten Aufprall auf den Tisch zu vermeiden und geringere Verzögerungswerte für den Insassen zu erreichen. Alternatively, for example, depending on the prevailing circumstances, for example if the occupant is in a so-called relaxed position due to a corresponding seat adjustment, ie in a relaxed sitting position, ie for example with the vehicle seat tilted sharply backwards and additionally pushed backwards, for example, can be detected that airbags in other parts of the vehicle do not protect the occupants can achieve, so that the table is moved into such an occupant protection position that it supports at least a body portion, in particular the upper body, of the occupant against displacement caused by a collision. Here too, for example, the table airbag can also be deployed, in particular in the direction of the occupant, in order to avoid a hard impact on the table and to achieve lower deceleration values for the occupant.

Alternativ kann beispielsweise je nach vorliegenden Gegebenheiten, insbesondere wenn erkannt wird, dass die Sitzposition des Insassen bereits optimal für mindestens einen in einem anderen Fahrzeugteil angeordneten Airbag ist, der Tisch in eine derartige Insassenschutzposition bewegt werden, dass er eine Abstützfläche für diesen Airbag bildet und diesen somit während seiner Entfaltung optimal lenkt, führt und/oder stützt und/oder insbesondere im entfalteten Zustand abstützt. Alternatively, for example, depending on the prevailing circumstances, especially if it is recognized that the seating position of the occupant is already optimal for at least one airbag arranged in another part of the vehicle, the table can be moved into such an occupant protection position that it forms a support surface for this airbag and this thus optimally steers, guides and/or supports and/or in particular supports in the unfolded state during its unfolding.

Einander entsprechende Teile sind in allen Figuren mit den gleichen Bezugszeichen versehen. Corresponding parts are provided with the same reference symbols in all figures.

Anhand der Figuren 1 bis 11 werden im Folgenden eine Insassenschutzvorrichtung 1 für ein Fahrzeug 2, ein Fahrzeug 2 mit mindestens einer solchen Insassenschutzvorrichtung 1 und ein Verfahren zum Betrieb einer solchen Insassenschutzvorrichtung 1 beschrieben. Die Insassenschutzvorrichtung 1 umfasst mindestens einen einem Fahrzeugsitz 3 des Fahrzeugs 2 zugeordneten Tisch 4. Beispielsweise kann die Insassenschutzvorrichtung 1 mehrere solche Tische 4 aufweisen, beispielsweise ist mehreren oder allen Fahrzeugsitzen 3 des Fahrzeugs 2 jeweils ein solcher Tisch 4 zugeordnet, beispielsweise zumindest Rücksitzen und/oder einem Beifahrersitz. An occupant protection device 1 for a vehicle 2, a vehicle 2 with at least one such occupant protection device 1 and a method for operating such an occupant protection device 1 are described below with reference to FIGS. The occupant protection device 1 comprises at least one table 4 assigned to a vehicle seat 3 of the vehicle 2. For example, the occupant protection device 1 can have several such tables 4, for example one such table 4 is assigned to several or all vehicle seats 3 of the vehicle 2, for example at least rear seats and/or a passenger seat.

Der Tisch 4 ist beispielsweise aus einer Verstauposition in eine in den Figuren 1 und 2 dargestellte jeweilige Tischnutzungsposition und wieder zurück bewegbar, beispielsweise manuell und/oder elektrisch, insbesondere elektromotorisch. Die Tischnutzungsposition ist dabei beispielsweise abhängig von einer Sitzposition eines im Fahrzeugsitz 3 sitzenden Insassen I, wie in den Figuren 1 und 2 gezeigt. In Figur 1 befindet sich der Insasse I in einer aufrechten Sitzposition, auch als Standardsitzposition bezeichnet, und somit relativ nah an einem Cockpit 5, auch als Instrumententafel bezeichnet, des Fahrzeugs 2 und in Figur 2 in einer so genannten Relaxed-Position, d. h. in einer entspannten Sitzposition, in welcher beispielsweise der Fahrzeugsitz 3 nach hinten verschoben ist und/oder der Fahrzeugsitz 3 oder zumindest eine Sitzlehne des Fahrzeugsitzes 3 nach hinten geneigt ist und der Insasse I somit weiter entfernt ist vom Cockpit 5. In den Figuren 7 und 8 ist die Tischnutzungsposition jeweils gestrichelt dargestellt. The table 4 can be moved, for example, from a stowed position into a respective table usage position shown in FIGS. 1 and 2 and back again, for example manually and/or electrically, in particular by an electric motor. The position in which the table is used depends, for example, on the seating position of someone sitting in the vehicle seat 3 Occupant I as shown in Figures 1 and 2. In Figure 1, the occupant I is in an upright seating position, also known as the standard seating position, and thus relatively close to a cockpit 5, also known as the instrument panel, of the vehicle 2 and in Figure 2 in a so-called relaxed position, ie in a relaxed seating position, in which, for example, the vehicle seat 3 is pushed backwards and/or the vehicle seat 3 or at least one seat backrest of the vehicle seat 3 is tilted backwards and the occupant I is therefore further away from the cockpit 5. In Figures 7 and 8, the Table usage position shown in dashed lines.

Der Tisch 4 ist beispielsweise, insbesondere über einen Tischhalter 6, mit einer Mittelkonsole 7 des Fahrzeugs 2 gekoppelt. Die Verstauposition befindet sich beispielsweise an oder in dieser Mittelkonsole 7. Die Mittelkonsole 7 ist aus Gründen der Übersichtlichkeit nur in Figur 1, und hier nur beispielhaft und schematisch stark vereinfacht, dargestellt. The table 4 is coupled to a center console 7 of the vehicle 2, for example, in particular via a table holder 6. The stowage position is, for example, on or in this center console 7. For reasons of clarity, the center console 7 is only shown in FIG.

Der Tisch 4 ist beispielsweise als ein Klapptisch ausgebildet. The table 4 is designed, for example, as a folding table.

Durch das Vorsehen eines solchen Tischs 4 für den Fahrzeugsitz 3 wird insbesondere dem Umstand Rechnung getragen, dass ein zunehmender Bedarf besteht, während der Fahrt des Fahrzeugs 2 zu arbeiten. Dies betrifft beispielsweise einen Beifahrer oder einen Mitfahrer auf einem Rücksitz des Fahrzeugs 2, bei automatisierter, insbesondere hochautomatisierter oder autonomer, Fahrt des Fahrzeugs 2 auch einen Fahrzeugführer des Fahrzeugs 2. The provision of such a table 4 for the vehicle seat 3 takes into account in particular the fact that there is an increasing need to work while the vehicle 2 is driving. This relates, for example, to a passenger or a passenger in a back seat of vehicle 2, and in the case of automated, in particular highly automated or autonomous, driving of vehicle 2, also to a driver of vehicle 2.

Beispielsweise hierfür kann der Insasse I den, insbesondere ausklappbaren, Tisch 4 nutzen. Beispielsweise weist der Tisch 4 hierfür mindestens eine Eingabeeinheit und/oder mindestens eine Anzeigeeinheit und/oder mindestens eine akustische Ausgabeeinheit auf. Die Eingabeeinheit ist beispielsweise eine Tastatur, ein taktiles Display oder eine Projektion mit Gestikerkennung. For example, the occupant I can use the table 4, which in particular can be folded out, for this purpose. For example, the table 4 has at least one input unit and/or at least one display unit and/or at least one acoustic output unit for this purpose. The input unit is, for example, a keyboard, a tactile display or a projection with gesture recognition.

Problematisch bei einem solchen Tisch 4 ist, dass er in einer Unfallsituation, d. h bei einer Kollision des Fahrzeugs 2, eine mögliche Gefahr für die Insassensicherheit darstellt. Zudem reduziert sich in der entspannten, d. h. zurückgelagerten, Sitzposition zunehmend eine Schutzwirkung herkömmlicher Rückhaltesysteme, insbesondere eines Frontalairbags. Um diese Probleme bezüglich des Insassenschutzes zu lösen, ist vorgesehen, dass der mindestens eine Tisch 4, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision und/oder Kollisionsgefahr des Fahrzeugs 2, insbesondere aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in mindestens eine Insassenschutzposition bewegbar ist, in der er zumindest einen Körperabschnitt, insbesondere einen Oberkörper, des Insassen I gegen eine kollisionsbedingte Verlagerung abstützt und/oder eine Abstützfläche für mindestens einen sich aus einem anderen Fahrzeugteil entfaltenden Airbag 8 bildet.The problem with such a table 4 is that in an accident situation, i. h in the event of a collision of the vehicle 2, represents a possible risk for the safety of the occupants. In addition, in the relaxed, ie reclined, seating position, the protective effect of conventional restraint systems, in particular a frontal airbag, is increasingly reduced. In order to solve these problems with regard to occupant protection, it is provided that the at least one table 4, in particular from the table use position and/or from the stowed position, when a collision and/or risk of collision of the vehicle 2 is detected, in particular actively, ie in particular electrically, in particular driven by an electric motor and/or pneumatically and/or hydraulically and/or pyrotechnically, in particular automatically, into at least one occupant protection position in which it supports at least a body section, in particular an upper body, of the occupant I against displacement caused by a collision and/or a support surface for at least one airbag 8 deploying from another part of the vehicle.

Diese Abstützfläche ist insbesondere zum Lenken, Führen und/oder Stützen des Airbags 8 während dessen Entfaltung und/oder insbesondere zum Abstützen des entfalteten Airbags 8 vorgesehen. Insbesondere umfasst die Insassenschutzvorrichtung 1 auch den mindestens einen Airbag 8 oder mehrere solche Airbags 8. This support surface is provided in particular for directing, guiding and/or supporting the airbag 8 during its deployment and/or in particular for supporting the deployed airbag 8 . In particular, the occupant protection device 1 also includes the at least one airbag 8 or several such airbags 8.

Der elektrische, insbesondere elektromotorische, und/oder pneumatische und/oder hydraulische Antrieb ermöglicht insbesondere eine reversible Bewegung des Tischs 4. Dies ist insbesondere vorteilhaft bei einer erkannten Kollisionsgefahr, wobei noch die Möglichkeit besteht, die Kollision zu verhindern. Die pyrotechnische Bewegung ist besonders schnell und dadurch insbesondere für eine erkannte bereits erfolgende Kollision des Fahrzeugs 2 geeignet. The electrical, in particular electromotive, and/or pneumatic and/or hydraulic drive enables, in particular, a reversible movement of the table 4. This is particularly advantageous when a risk of collision is identified, although there is still the possibility of preventing the collision. The pyrotechnic movement is particularly fast and is therefore particularly suitable for a collision of the vehicle 2 that has already been detected.

Alternativ oder zusätzlich zu diesem Bewegen in die Insassenschutzposition kann beispielsweise vorgesehen sein, dass der Tisch 4 mindestens ein aufblasbares Schutzsystem aufweist, im Folgenden als Tischairbag 9 bezeichnet. Der Tischairbag 9 ist bei der erkannten Kollision oder Kollisionsgefahr des Fahrzeugs 2, insbesondere durch Aktivieren, insbesondere Zünden, mindestens eines Gasgenerators entfaltbar, wie in Figur 3 für die aufrechte Sitzposition und in Figur 4 für die entspannte Sitzposition gezeigt. Der Tischairbag 9 ist dabei vorteilhafterweise derart im Tisch 4 integriert, dass er zusammen mit dem Tisch 4 bewegt wird. Dadurch wird es ermöglicht, sowohl den Insassen I vor einem harten Kontakt mit dem Tisch 4 zu schützen als auch den in die entspannte Position zurückverlagerten Insassen I frühzeitig abzufangen. As an alternative or in addition to this movement into the occupant protection position, provision can be made, for example, for the table 4 to have at least one inflatable protection system, referred to below as a table airbag 9 . The table airbag 9 can be deployed when a collision or risk of collision of the vehicle 2 is detected, in particular by activating, in particular igniting, at least one gas generator, as shown in FIG. 3 for the upright sitting position and in FIG. 4 for the relaxed sitting position. The table airbag 9 is advantageously integrated in the table 4 in such a way that it is moved together with the table 4 . This makes it possible both to protect the occupant I from hard contact with the table 4 and to catch the occupant I shifted back to the relaxed position early.

Der Tisch 4, insbesondere die mindestens eine Eingabeeinheit, Ausgabeeinheit und/oder Anzeigeeinheit, ist zum Freigeben der Entfaltung des Tischairbags 9 mit einer Öffnung, beispielsweise einer Reißklappe wie bei Airbagssystemen oder mechanisch und/oder elektrisch freischaltbar, versehen, durch die sich der Tischairbag 9 entfalten kann, insbesondere in Richtung des Insassen I und/oder nach oben. In den Figuren 3 und 4 ist eine dabei geöffnete Airbagklappe 10 dargestellt, welche im geschlossenen Zustand bei nicht entfaltetem Tischairbag 9 die Öffnung verschließt. The table 4, in particular the at least one input unit, output unit and/or display unit, is provided with an opening to release the deployment of the table airbag 9, for example a tear flap as in airbag systems or which can be released mechanically and/or electrically, through which the table airbag 9 can unfold, in particular in the direction of the occupant I and / or upwards. In Figures 3 and 4 is an open airbag flap 10 is shown, which in the closed state closes the opening when the table airbag 9 is not deployed.

Wie oben bereits erwähnt, ist der mindestens eine Tisch 4, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision und/oder Kollisionsgefahr des Fahrzeugs 2, insbesondere aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in mindestens eine Insassenschutzposition bewegbar. Hierzu ist er beispielsweise, insbesondere relativ zu seinem Tischhalter 6, um mindestens eine Drehachse DA drehbar, wie in Figur 5 gezeigt, wobei der Tisch 4 hier in einer gedrehten Position und zusätzlich gestrichelt in einer Position vor dem Drehen dargestellt ist. As already mentioned above, the at least one table 4, in particular from the table usage position and/or from the stowed position, is in particular active, i. H. in particular electrically, in particular by an electric motor, and/or pneumatically and/or hydraulically and/or pyrotechnically driven, in particular automatically, movable into at least one occupant protection position. For this purpose it can be rotated about at least one axis of rotation DA, in particular relative to its table holder 6, as shown in FIG.

Alternativ oder zusätzlich ist der Tisch 4 beispielsweise, insbesondere relativ zu seinem Tischhalter 6 oder zusammen mit seinem Tischhalter 6, um mindestens eine Achse schwenkbar und/oder, wie durch Verschiebepfeile P dargestellt, entlang mindestens einer Achse, insbesondere relativ zu seinem Tischhalter 6, verschiebbar, d. h. translatorisch verschiebbar. Vorteilhafterweise ist eine Kombination mehrerer dieser Bewegungsmöglichkeiten oder aller genannten Bewegungsmöglichkeiten vorgesehen. Es kann beispielsweise, alternativ oder zusätzlich, auch vorgesehen sein, dass der Tisch 4 mittels seines Tischhalters 6 auf die beschriebene Weise drehbar, schwenkbar und/oder verschiebbar ist, verschiebbar beispielsweise durch Verlängern oder Verkürzen des Tischhalters 6, schwenkbar beispielsweise durch Schwenken des Tischhalters 6. Es wird dadurch insbesondere ermöglicht, dass sich der mindestens eine Tischairbag 9 und/oder der mindestens eine im anderen Fahrzeugteil angeordnete Airbag 8 optimiert am Tisch 4 abstützen kann und/oder dass der Tisch 4 zumindest einen Körperabschnitt, insbesondere den Oberkörper, des Insassen I gegen eine kollisionsbedingte Verlagerung abstützen kann. Alternatively or additionally, the table 4 can, for example, be pivoted about at least one axis, in particular relative to its table holder 6 or together with its table holder 6, and/or, as represented by displacement arrows P, can be displaced along at least one axis, in particular relative to its table holder 6 , i.e. H. translationally displaceable. Advantageously, a combination of several of these movement options or all of the movement options mentioned is provided. For example, alternatively or additionally, it can also be provided that the table 4 can be rotated, pivoted and/or displaced in the manner described by means of its table holder 6, displaceable, for example, by lengthening or shortening the table holder 6, pivoted, for example, by pivoting the table holder 6 This makes it possible, in particular, for the at least one table airbag 9 and/or the at least one airbag 8 arranged in the other part of the vehicle to be optimally supported on the table 4 and/or for the table 4 to support at least one part of the body, in particular the upper body, of occupant I can support against a collision-related displacement.

Alternativ oder zusätzlich kann beispielsweise vorgesehen sein, dass sich der Tischairbag 9 an einer Unterseite des Tischs 4 entfaltet und dann beispielsweise als Knieairbag zum Schutz von Becken und/oder Beinen, insbesondere Oberschenkeln und/oder Knien, des Insassen I dient, wie in Figur 6 gezeigt, insbesondere um Becken und Oberschenkel besser zu fixieren und/oder die Knie vor einem harten Aufprall auf das Cockpit 5 zu schützen. Beispielsweise kann der Tisch 4 mehrere solche Tischairbags 9 aufweisen, wobei sich beispielsweise einer nach oben und einer nach unten entfalten kann, oder in einer besonders vorteilhaften Ausführungsform weist der Tisch 4 nur einen Tischairbag 9 auf, welcher dann durch das beschriebene Bewegen des Tischs 4 in die an die jeweils vorliegenden Gegebenheiten angepasste Insassenschutzposition entsprechend ausgerichtet wird. Alternatively or additionally, it can be provided, for example, that the table airbag 9 unfolds on the underside of the table 4 and then serves, for example, as a knee airbag to protect the pelvis and/or legs, in particular thighs and/or knees, of the occupant I, as in Figure 6 shown, in particular to better fix the pelvis and thighs and / or to protect the knees from a hard impact on the cockpit 5. For example, the table 4 can have several such table airbags 9, one being able to unfold upwards and one downwards, for example, or in a particularly advantageous embodiment the table 4 has only one Table airbag 9, which is then aligned accordingly by the described movement of the table 4 in the occupant protection position adapted to the prevailing circumstances.

Beispielsweise kann dann, je nach vorliegenden Gegebenheiten bei erkannter Kollision oder Kollisionsgefahr, vorgesehen sein, dass sich dieser Tischairbag 9 an einer eine Oberseite des Tischs 4 bildenden Fläche entfaltet, zum Beispiel nach oben und/oder in Richtung des Insassen I, um den Oberkörper und/oder Kopf des Insassen I zu schützen, wie in den Figuren 3 und 4 gezeigt, oder durch ein entsprechendes Bewegen, insbesondere Drehen, des Tischs 4 an einer dann eine Unterseite des Tischs 4 bildenden Fläche entfaltet, um das Becken und/oder die Beine, insbesondere die Oberschenkel und/oder Knie, des Insassen I zu schützen, wie in Figur 6 gezeigt, insbesondere um Becken und Oberschenkel besser zu fixieren und/oder die Knie vor einem harten Aufprall auf das Cockpit 5 zu schützen. For example, depending on the prevailing circumstances when a collision or risk of a collision is detected, it can be provided that this table airbag 9 unfolds on a surface forming an upper side of the table 4, for example upwards and/or in the direction of the occupant I, around the upper body and /or to protect the head of the occupant I, as shown in Figures 3 and 4, or by correspondingly moving, in particular rotating, the table 4 on a surface then forming an underside of the table 4 unfolds around the pelvis and/or the legs , in particular the thighs and/or knees, of the occupant I, as shown in FIG.

Wie bereits beschrieben, ist vorteilhafterweise vorgesehen, dass der mindestens eine Tisch 4, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision und/oder Kollisionsgefahr des Fahrzeugs 2, insbesondere aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in mindestens eine Insassenschutzposition bewegbar ist, in der er zumindest einen Körperabschnitt, insbesondere den Oberkörper, des Insassen I gegen eine kollisionsbedingte Verlagerung abstützt. Dies ist in Figur 7 für die aufrechte Sitzposition und in Figur 8 für die entspannte Sitzposition des Insassen I beispielhaft dargestellt. Dies ist insbesondere vorteilhaft bei einer erkannten Kollisionsgefahr, wobei der Tisch 4 kurz vor der Kollision präventiv, auch als „pre safe“ bezeichnet, in diese Insassenschutzposition bewegt wird. Durch dieses Positionieren des Tischs 4 vor dem Oberkörper, insbesondere vor der Brust, wird eine flächige Rückhaltung des Insassen I ermöglicht, wodurch eine Last auf dem Brustkorb des Insassen I reduziert wird. Beispielsweise kann zusätzlich vorgesehen sein, dass sich der Tischairbag 9 in Richtung des Insassen I entfaltet. As already described, it is advantageously provided that the at least one table 4, in particular from the table usage position and/or from the stowed position, is in particular actively, i. H. driven, in particular electrically, in particular by an electric motor, and/or pneumatically and/or hydraulically and/or pyrotechnically, in particular automatically, into at least one occupant protection position, in which it supports at least one body section, in particular the upper body, of occupant I against displacement caused by a collision. This is shown by way of example in FIG. 7 for the upright sitting position and in FIG. 8 for the relaxed sitting position of occupant I. This is particularly advantageous when a risk of collision is detected, with the table 4 being moved into this occupant protection position shortly before the collision as a preventive measure, also referred to as “pre safe”. This positioning of the table 4 in front of the upper body, in particular in front of the chest, enables the occupant I to be restrained over a large area, as a result of which a load on the occupant I's chest is reduced. For example, it can also be provided that the table airbag 9 unfolds in the direction of the occupant I.

Wie bereits beschrieben, ist vorteilhafterweise vorgesehen, dass der mindestens eine Tisch 4, insbesondere aus der Tischnutzungsposition und/oder aus der Verstauposition, bei einer erkannten Kollision und/oder Kollisionsgefahr des Fahrzeugs 2, insbesondere aktiv, d. h. insbesondere elektrisch, insbesondere elektromotorisch, und/oder pneumatisch und/oder hydraulisch und/oder pyrotechnisch angetrieben, insbesondere automatisch, in mindestens eine Insassenschutzposition bewegbar ist, in der er eine Abstützfläche für den mindestens einen sich aus einem anderen Fahrzeugteil entfaltenden Airbag 8 bildet. Diese Abstützfläche ist insbesondere zum Lenken, Führen und/oder Stützen des Airbags 8 während dessen Entfaltung und/oder insbesondere zum Abstützen des entfalteten Airbags 8 vorgesehen. Insbesondere umfasst die Insassenschutzvorrichtung 1 auch den mindestens einen Airbag 8. Beispiele für diese Ausführungsform sind in den Figuren 9 und 10 dargestellt. Dabei zeigt Figur 9 einen sich aus dem als Cockpit 5 ausgebildeten weiteren Fahrzeugteil entfaltenden Airbag 8, welcher auch als Frontalairbag bezeichnet wird, und Figur 10 zeigt einen sich aus einem Fahrzeugteil entfaltenden Airbag 8, welches als ein dem Fahrzeugsitz 3 zugeordneter Sicherheitsgurt 11 ausgebildet ist. Ein solcher Airbag 8 wird auch als Beltbag bezeichnet. As already described, it is advantageously provided that the at least one table 4, in particular from the table use position and/or from the stowed position, when a collision and/or risk of collision of the vehicle 2 is detected, in particular actively, ie in particular electrically, in particular by an electric motor, and/or or driven pneumatically and/or hydraulically and/or pyrotechnically, in particular is automatically movable into at least one occupant protection position in which it forms a support surface for the at least one airbag 8 deploying from another part of the vehicle. This support surface is provided in particular for directing, guiding and/or supporting the airbag 8 during its deployment and/or in particular for supporting the deployed airbag 8 . In particular, the occupant protection device 1 also includes the at least one airbag 8. Examples of this embodiment are shown in FIGS. FIG. 9 shows an airbag 8 unfolding from the additional vehicle part designed as a cockpit 5, which is also referred to as a frontal airbag, and FIG. Such an airbag 8 is also referred to as a beltbag.

Alternativ oder zusätzlich kann der Tisch 4 auf die beschriebene Weise beispielsweise auch, insbesondere präventiv, d. h. bereits bei einer erkannten Kollisionsgefahr, in eine Sicherheitsposition bewegt werden, in der der Tisch 4 eine Schutzwirkung einer oder mehrerer anderer vorhandener Sicherheitskomponenten des Fahrzeugs 2 erhöht. Alternatively or additionally, the table 4 can, for example, in the manner described also, in particular preventively, d. H. be moved into a safety position, in which the table 4 increases a protective effect of one or more other existing safety components of the vehicle 2, even if there is a risk of collision.

Die Insassenschutzposition, in welche der Tisch 4 bei einer erkannten Kollision oder Kollisionsgefahr bewegbar ist bzw. bewegt wird, ist beispielsweise abhängig von einer Art der erkannten Kollision oder Kollisionsgefahr, zum Beispiel Front-, Seiten- oder Heckkollision oder Gefahr hierfür, und/oder von einer Sitzposition des Insassen I, und/oder von einer Sitzeinstellung des Fahrzeugsitzes 3, und/oder von einem Anlegezustand des dem Fahrzeugsitz 3 zugeordneten Sicherheitsgurtes 11, d. h. ob dieser vom Insassen I ordnungsgemäß angelegt ist oder nicht, insbesondere ob ein Gurtschloss geschlossen ist oder nicht, und/oder von einer Ausrichtung des Insassen I und/oder des Fahrzeugsitzes 3 relativ zu dem mindestens einen abzustützenden Airbag 8. The occupant protection position into which the table 4 can be moved or is moved when a collision or risk of a collision is detected depends, for example, on the type of collision or risk of collision detected, for example a front, side or rear collision or the risk thereof, and/or on a seating position of the occupant I, and/or a seat adjustment of the vehicle seat 3, and/or an application state of the seat belt 11 assigned to the vehicle seat 3, d. H. whether the occupant I put it on properly or not, in particular whether a belt buckle is closed or not, and/or the orientation of the occupant I and/or the vehicle seat 3 relative to the at least one airbag 8 to be supported.

Figur 11 zeigt eine schematisch stark vereinfachte Darstellung des Fahrzeugs 2 mit der Insassenschutzvorrichtung 1. Die Insassenschutzvorrichtung 1 umfasst im dargestellten Beispiel den Tisch 4, beispielsweise mit seinem Tischhalter 6 und beispielsweise mit seinem Tischairbag 9, beispielsweise den mindestens einen sich aus einem anderen Fahrzeugteil entfaltenden Airbag 8, sowie beispielsweise eine Kollisionssensorik 12 zur Erkennung einer Kollision und/oder Kollisionsgefahr, insbesondere auch zur Erkennung der Art der Kollision oder Kollisionsgefahr, zum Beispiel Front-, Seiten- oder Heckkollision oder Gefahr hierfür, und/oder eine Insassenpositionssensorik 13 zur Erkennung einer Sitzposition des Insassen I, und/oder eine Sitzeinstellungssensorik 14 zur Erkennung einer Sitzeinstellung des Fahrzeugsitzes 3 und/oder eine Ausrichtungssensorik 15 zur Erkennung einer Ausrichtung des Insassen I und/oder des Fahrzeugsitzes 3 relativ zu dem mindestens einen abzustützenden Airbag 8. Figure 11 shows a highly simplified schematic representation of the vehicle 2 with the occupant protection device 1. In the example shown, the occupant protection device 1 comprises the table 4, for example with its table holder 6 and for example with its table airbag 9, for example the at least one airbag deployed from another part of the vehicle 8, as well as, for example, a collision sensor system 12 for detecting a collision and/or the risk of a collision, in particular also for detecting the type of collision or the risk of a collision, for example a front, side or rear collision or the risk thereof, and/or an occupant position sensor system 13 for detecting a seat position of the occupant I, and/or a seat adjustment sensor system 14 for detection a seat adjustment of the vehicle seat 3 and/or an orientation sensor system 15 for detecting an orientation of the occupant I and/or the vehicle seat 3 relative to the at least one airbag 8 to be supported.

Die Kollisionssensorik 12 kann beispielsweise mindestens einen Kamerasensor, Lidarsensor, Ultraschallsensor, Radarsensor, Kraftsensor, Verformungssensor, Bewegungssensor und/oder Beschleunigungssensor aufweisen. Es können auch vom jeweiligen Sensortyp mehrere Sensoren vorgesehen sein. Kamerasensor, Lidarsensor, Ultraschallsensor und/oder Radarsensor sind dabei insbesondere Bestandteil einer Umfelderfassungssensorik zur Erfassung eines äußeren Umfeldes des Fahrzeugs 2. The collision sensor system 12 can have, for example, at least one camera sensor, lidar sensor, ultrasonic sensor, radar sensor, force sensor, deformation sensor, motion sensor and/or acceleration sensor. Several sensors can also be provided for the respective sensor type. Camera sensor, lidar sensor, ultrasonic sensor and/or radar sensor are in particular part of an environment detection sensor system for detecting an external environment of vehicle 2.

Die Insassenpositionssensorik 13 kann beispielsweise mindestens einen Kamerasensor, Lidarsensor, Ultraschallsensor, Radarsensor, Kraftsensor, Verformungssensor, Bewegungssensor, Beschleunigungssensor, Gewichtssensor, Kontaktsensor, insbesondere Körperkontaktsensor, und/oder Sicherheitsgurtsensor aufweisen. Diese Sensoren sind insbesondere Bestandteil einer Innenraumüberwachung des Fahrzeugs 2. Es können auch vom jeweiligen Sensortyp mehrere Sensoren vorgesehen sein.
