ABSTRACT:
A vehicle seat constructed in accordance with principles of this invention comprises stopping means that serve to conduct forces introduced via a movable belt mounting point during a frontal impact directly to the side rail, without having to transmit the entire load via the adjusting mechanism. A vehicle seat includes a seat frame having a seat belt mounting point, and an upper rail that is connected to the seat frame by at least one adjusting lever and at least one compensating lever extending from the upper rail to the seat frame. The seat includes a height adjusting mechanism for adjusting the height of the seat frame. The height adjusting mechanism includes a drive shaft connected to an end of the adjusting lever, wherein rotation of the shaft effects vertical movement of the adjusting lever and height adjustment of the seat frame. The seat includes a stopping means that limits a maximum adjustment path of the seat frame, wherein in a stop position a belt force from the seat frame is introduced directly into the upper rail and bypasses the adjusting mechanism.
