VEHICLE SEAT COMPRISING A HEIGHT ADJUSTING DEVICE

摘要

The invention relates to a vehicle seat, especially a motor vehicle seat, comprising a height adjusting device (25) for adjusting the height of the frame (10) of the vehicle seat (1) in relation to a substructure (3) which is connected to the vehicle structure. In the event of a crash, an irreversible change in the geometry of the height adjusting device (25) activates at least one crash blocking mechanism (27, 30) which enables an alternative transmission of forces between the seat frame (10) and the substructure (3).
