Abstract

The protection system is U-shaped and consists of two small airbags on either side of the car seat headrest. Thus the head is surrounded on three sides and its free movement is effectively prevented, on the airbag activation, for the head and neck spine protection. The protection is especially effective on a lateral impact at any angle.

Description

Zum Sinn der Erfindung:
Verbesserung des Insassenunfallschutzes bei PKW, LKW und ähnlichen Fahrzeugen.For the purpose of the invention:
Improvement of occupant accident protection in cars, trucks and similar vehicles.

Zur Minderung der Unfallfolgen wurden in den vergangenen Jahren viele Systeme zum Schutz der Fahrzeuginsassen ent­ wickelt, erprobt und in die Praxis überführt. Fast alle Systeme bieten aber ihre Schutzwirkung nur an, bei einem Frontalaufprall oder einem Heckaufprall. Dagegen die Fahr­ zeugseiten sind ein besonderer Schwerpunkt im Falle eines Unfalles. Bedingt durch die geringe Kürze des Abstandes zwischen Fahrzeugseite, Insassen und den daraus resultie­ renden Weg Zeit Verhältnis lassen sich Schutzmaßnahmen nur schwer realisieren. Die Insassen des Fahrzeuges sind daher bei einem Unfall in die Seite des Fahrzeuges fast unge­ schützt. Die Verletzungen sind dementsprechend.To reduce the consequences of the accident have been in the past Years ago, many systems for protecting vehicle occupants develops, tests and puts into practice. Almost all Systems only offer their protective effect, with one Frontal impact or a rear impact. Against the driving Tool pages are a special focus in the case of a Accident. Due to the small shortness of the distance between vehicle side, occupants and the resulting Protective measures can only be taken on the way difficult to realize. The occupants of the vehicle are therefore almost accidentally in the side of the vehicle protects. The injuries are accordingly.

Um eine weitere Verbesserung zum Schutz der Insassen zu erreichen habe ich folgende Erfindung gemacht, das System der:
"Kleinairbags zum Schutz des Kopfes und der Halswirbelsäule".In order to achieve a further improvement for the protection of the occupants I made the following invention, the system of:
"Small airbags to protect the head and cervical spine".

Folgende Aufgabe liegt der Erfindung zugrunde:
Verletzungen am Kopf und an der Halswirbelsäule bei einem Unfall in die Fahrzeugseite wirksam zu unterdrücken. Diese Aufgabe wird durch die Merkmale der Ansprüche 1 bis 4 gelöst.The invention is based on the following object:
Effectively suppress injuries to the head and cervical spine in the event of an accident in the vehicle side. This object is solved by the features of claims 1 to 4.

Im ruhenden Zustand sind die Kleinairbags (2 und 3) zum Schutz des Kopfes und der Halswirbelsäule (im folgenden nur noch Kleinairbag genannt) untergebracht in der linken bzw. rechten Seite der Kopfstütze (1) eines Fahrzeuges. Nach Fig. 1 besteht das System aus drei Teilen, einem festen, der Kopfstütze (1) als Grundträger und den zwei aufblasbaren Teilen, den linken Kleinairbag (2) und den rechten Klein­ airbag (3).In the resting state, the small airbags ( 2 and 3 ) for protecting the head and cervical spine (hereinafter only called small airbag) are housed in the left and right side of the headrest ( 1 ) of a vehicle. According to Fig. 1, the system consists of three parts, a fixed, the headrest ( 1 ) as a base support and the two inflatable parts, the left small airbag ( 2 ) and the right small airbag ( 3 ).

Zur Funktion:
Bei einem Unfall quer zur Fahrzeuglängsachse wird der Kleinairbag mit sofortiger Wirkung aktiviert, d. h. aufge­ blasen. Vergleiche dazu Fig. 2, Fig. 3 und Fig. 4. Bedingt durch den geringen Abstand zwischen Fahrzeugseite und dem Kopf des Fahrzeuginsassen ist eine sofortige Aktivierung des Kleinairbag nötig.About the function:
In the event of an accident transversely to the vehicle's longitudinal axis, the small airbag is activated with immediate effect, ie inflated. Compare to Fig. 2, Fig. 3 and Fig. 4. Due to the small distance between the vehicle side and the head of the vehicle occupant is needed for an immediate activation of the small air bag.

Im folgenden wird die Schutzwirkung der Kleinairbags dar­ gestellt:
Mit dem Eindringen eines Fahrzeuges in die Seitenpartie eines anderen Fahrzeuges, also mit Beginn des Unfalles wird der Kleinairbag von der Auslösevorichtung aktiviert. Es werden beide Teile des Kleinairbag aufgeblasen ((4) und (5)). Mit der U-förmigen Schutzvorrichtung nach Fig. 2, die jetzt entstanden ist, kann der Kopf und die Halswirbelsäule des Fahrzeuginsassen sehr wirksam gegen die Auswirkungen eines Seitenaufpralles, oder eines schräg versetzten Unfalles ge­ schützt werden. Denn diese Schutzvorrichtung zeichnet sich dadurch aus, daß der Kopf wirksam von 3-Seiten umschlossen wird. Die Öffnung der U-förmigen Schutzvorrichtung nach Fig. 2 zeigt in Richtung Fahrzeuglängsachse. Nach dem erfolg­ ten Unfall in die Seite des Fahrzeuges wird der Kopf des Fahrzeuginsassen nach den Regeln der Physik bewegt. Als erster Vorgang erfolgt die Bewegung entgegen der Eindring­ richtung des Unfallverursachenden Fahrzeuges. Das Beharrungs­ vermögen des relativ schweren Kopfes führt zu einer starken Biegung der Halswirbelsäule, mit all ihren bekannten Schäden. Durch die zunehmende Beschleunigung des Fahrzeuges, der Fahr­ zeuginsassen und der weiter voranschreitenden Verspannung der Halswirbelsäule wird nach endlicher Zeit die Bewegungs­ richtung des Kopfes umgekehrt. Der relativ schwere Kopf wird jetzt mit in die Eindringrichtung des unfallverursachenden Fahrzeuges bewegt. Das bedeutet, die Halswirbelsäule erfährt jetzt eine starke Biegung in die andere Richtung. Das heißt sie wird überlastet. Zwangsläufigerweise muß die Halswirbel­ säule alle Bewegungen des sich bewegenden Kopfes mitmachen. Sie wird erst in die eine Richtung verspannt, anschließend in die andere Richtung verspannt. Im Falle eines Unfalles, quer oder schräg versetzt zur Fahrtrichtung darf diese freie Beweglichkeit des Kopfes nicht gegeben sein! Mittels einer wirksamen Schutzvorrichtung nach Fig. 2, Fig. 3 und Fig. 4 ist es möglich den Kopf und auch die Halswirbelsäule ruhig zustellen. Das bedeutet in der Praxis Unfallschäden vom Fahrzeuginsassen fernzuhalten. Dazu habe ich das System der Kleinairbags zum Schutze des Kopfes und der Halswirbelsäule erfunden.The protective effect of the small airbags is shown below:
When a vehicle enters the side of another vehicle, i.e. at the beginning of the accident, the small airbag is activated by the triggering device. Both parts of the small airbag are inflated (( 4 ) and ( 5 )). U-shaped with the protective device according to Fig. 2, which is now formed, the head and cervical spine of the passenger can be very effective against the effect of a side impact, or of an obliquely offset accident ge protects be. Because this protective device is characterized in that the head is effectively enclosed on 3 sides. The opening of the U-shaped protective device according to FIG. 2 points in the direction of the vehicle's longitudinal axis. After the accident in the side of the vehicle, the head of the vehicle occupant is moved according to the rules of physics. The first process is the movement against the direction of penetration of the vehicle causing the accident. The persistence of the relatively heavy head leads to a strong bend in the cervical spine, with all its known damage. Due to the increasing acceleration of the vehicle, the vehicle occupants and the ongoing tension in the cervical spine, the direction of movement of the head is reversed after a finite time. The relatively heavy head is now moved in the direction of penetration of the vehicle causing the accident. This means that the cervical spine is now bent sharply in the other direction. That means it is overloaded. Inevitably, the cervical spine must follow all the movements of the moving head. It is first braced in one direction, then braced in the other direction. In the event of an accident, transverse or diagonal to the direction of travel, this free mobility of the head must not be given! By means of an effective protective device according to Fig. 2, Fig. 3 and Fig. 4, it is possible to identify the head and the cervical spine quiet. In practice, this means keeping accident damage away from the vehicle occupants. I invented the small airbag system to protect the head and cervical spine.
