Abstract
Description
Die Erfindung betrifft einen Fahrzeugsitz, insbesondere einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a vehicle seat, in particular a motor vehicle seat, with the features of the preamble of claim 1.
Es sind sowohl Fahrzeugsitze dieser Art bekannt, bei denen die Sitzschale eine feste Antisubmariningrampe trägt, als auch solche, bei denen sich die Antisubmariningrampe erst im Crashfall aufstellt. In beiden Varianten verhindert die Antisubmariningrampe, daß der Insasse beim Frontcrash unter dem Beckengurtabschnitt des ansprechenden Sicherheitsgurtes hindurchtaucht und sich verletzt.It Both vehicle seats of this type are known in which the seat pan carries a solid anti-submarine ramp, as well as those in which the anti-submarine ramp will only set up in the event of a crash. In both Variants prevents the anti-submarine ramp that the occupant in the frontal crash under the lap belt section of the appealing Safety belt penetrates and injured.
Der Erfindung liegt die Aufgabe zu Grunde, bei einem Fahrzeugsitz der eingangs genannten Art die Verletzungsgefahr zu verringert. Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, in a vehicle seat of initially mentioned type reduces the risk of injury. These Task is achieved by a vehicle seat with the features of claim 1 solved. advantageous Embodiments are the subject of the dependent claims.
Dadurch, daß die Antisubmariningrampe bezüglich ihrer Höhe asymmetrisch (d.h. nicht spiegelsymmetrisch) zu wenigstens einer x-z-Mittelebene des Fahrzeugsitzes ausgebildet ist (welche im Idealfall durch den Hüftpunkt des Insassens verläuft, wird die konstruktionsbedingte Asymmetrie des Sicherheitsgurtes zumindest annähernd ausgeglichen, so daß die Bahn des Hüftpunktes des Insassens, d.h. seines Schwerpunktes, zumindest annähernd in x-Richtung verläuft. Indem eine aufgrund der Asymmetrie des Sicherheitsgurtes schwellerseitig gerichtete Bewegung vermieden wird, verringert sich die Verletzungsgefahr. Für die Anwendung bei Fahrzeugsitzen gibt es keine Beschränkungen.Thereby, that the Anti submarine ramp with respect to their height asymmetric (i.e., not mirror-symmetric) to at least one x-z-median plane of the vehicle seat is formed (which in the ideal case through the hip point of the occupant runs, becomes the design-related asymmetry of the safety belt at least approximately balanced, so that the Tract of the hip point of the occupant, i. of its center of gravity, at least approximately in the x-direction runs. By one due to the asymmetry of the seat belt swelling side directional movement is avoided, the risk of injury is reduced. For the There are no restrictions on vehicle seat applications.
Die beispielsweise durch den Flächenschwerpunkt der Schnittflächen der Antisubmariningrampe in den x-z-Ebenen oder durch die größte Höhe zu jeder y-Koordinate beschriebene Asymmetrie kann sowohl rein in y-Richtung als auch zusätzlich in x-Richtung (als Versatz der Flächenschwerpunkte oder größten Höhen) vorhanden sein, was eine bestmögliche Anpassung an das vorhandene System von Fahrzeugsitz, Sicherheitsgurt und Insasse ermöglicht. Im allgemeinen Fall verläuft daher der Kamm der Antisubmariningrampe, welcher durch die Verbindungslinie der größten Höhen der Antisubmariningrampe zu jeder y-Koordinate definiert ist und erfindungsgemäß wenigstens in y-Richtung verschiedene Höhen aufweist, schräg zu allen Raumrichtungen, während er bei einer symmetrischen Rampe rein in y-Richtung verlaufen würde. In bevorzugter Ausführung weist der Kamm am tunnelseitigen Ende eine größere Höhe auf als am schwellerseitigen Ende, um die Tauchbewegung am tunnelseitigen Ende besser zu verhindern. Vorzugsweise ist das schwellerseitige Ende des Kammes in x-Richtung weiter vorne angeordnet als das tunnelseitige Ende des Kammes, um im Crashfall frühzeitig die Tauchbewegung am tunnelseitigen Ende zu verhindern.The for example, by the centroid the cut surfaces the anti-submarine ramp in the x-z planes or by the highest altitude to each y-coordinate described asymmetry can both purely in the y direction as well as in addition x direction (as an offset of the centroids or greatest heights) available be what a best possible Adaptation to the existing system of vehicle seat, seatbelt and inmates. In the general case runs hence the crest of the anti-submarine ramp which passes through the connecting line the highest heights of the Antisubmariningrampe to each y-coordinate is defined and according to the invention at least in the y-direction different heights has, obliquely to all spatial directions while he would run purely in y-direction at a symmetrical ramp. In preferred embodiment the comb at the tunnel end has a greater height than at the side of the sill End to better prevent the diving movement at the tunnel end. Preferably, the swelling-side end of the comb is in the x-direction arranged further forward than the tunnel-side end of the comb to in the Crash case early to prevent the dipping movement at the tunnel end.
Die Antisubmariningrampe kann statisch ausgebildet sein, d.h. immer vorhanden sein, so daß keine gesonderte Aktivierung erfolgen muß, oder dynamisch ausgebildet sein, was den Sitzkomfort im Normalfall, d.h. außerhalb des Crashfalls, erhöht. Letztere Alternative kann beispielsweise durch einen Bügel realisiert werden, der sich vorzugsweise erst im Crashfall aufrichtet. Erstere Alternative kann beispielsweise durch einen festen Bügel, einen festen Rampenkörper, eine lokal unterschiedliche Schaumhärte oder eine lokal unterschiedliche Geometrie der Sitzschale realisiert sein, wobei die letzten drei Möglichkeiten einen allmählichen Anstieg zum Kamm hin erlauben.The Antisubmariningrampe may be static, i. always be present so that no separate activation must be made, or designed dynamically what the seating comfort in the normal case, i. outside the crash, increased. Latter Alternative can be realized for example by a bracket, the preferably erects only in the event of a crash. First alternative For example, by a fixed bracket, a fixed ramp body, a locally different foam hardness or realized a locally different geometry of the seat be the last three ways a gradual Allow rise to the ridge.
