Abstract:
Motor vehicle seat to be arranged in a fore and aft direction in a motor vehicle so a person occupying the seat faces forward in the normal forward direction of travel of the motor vehicle comprising:(1) a seat part,(2) a backrest part situated aft of the seat part,(3) a holder member carried by the backrest part extending forwardly alongside the seat part and lying adjacent to the seat part with portions of the seat part situated below the holder member,(4) a load limiting device comprising mutually cooperating members defined by the adjacent lying portions of the seat part and the holder member for holding the seat part and the holder member, and in turn, the backrest part in a fixed relative juxtaposition, but allowing the seat part to move rearwardly relative to the backrest part when subjected to a rear impact of greater than a given force,(5) a first linkage, inclined forwardly, pivotally mounted at one end to the holder member, and at its other end to the portion of the seat part lying below the holder member,(6) a second linkage, inclined forwardly, mounted rearwardly of the first linkage with one end pivotally mounted to the holder, and its other end pivotally mounted to the portion of the seat part lying below the holder member,(7) the second linkage being longer than the first linkage, and(8) the load limiting device, upon activation by a rear impact of greater than the given force, allowing the seat part to move rearwardly relative to the holder member, and in turn, the backrest part, while said first and second linkages pivot in response to such movement to cause the backrest part to tend to tilt forwardly.
