Title: VEHICLE SEAT WITH BLOCKING DEVICE FOR A LOWERABLE SEAT PART OF THE VEHICLE SEAT
Abstract:
The invention relates to a vehicle seat having a base (B) and an adjustable seat part (SW), which can be lowered at least with a front portion in the direction of the base (B) when a backrest of the vehicle seat is tilted forward. A guide element (7) is provided which can be displaced on a guide slot (20) for the guide element (7) from a first portion (201) of a guide slot (20) to a second portion (202) of the guide slot (20) when the front portion of the seat part (SW) is lowered. According to the invention, - the guide slot (20) or the guide element (7) is provided on a blocking element (2a, 2b) of a blocking device (1 ) of the vehicle seat and - the blocking element (2a, 2b) can be displaced with the guide slot (20) or with the guide element (7) relative to the base (B) under the effect of acceleration forces occurring in the event of a crash, said displacement being such that, in the event of a crash, the guide element (7) moves from the first portion (201) of the guide slot and rests in a blocking position on a third portion (303) of the guide slot (20) that differs from the first and second portions (201, 202), said blocking position preventing the front portion of the seat part (SW) from being lowered.
