Abstract
Abstract A motor vehicle seat, especially a rear seat for a station wagon whose seat cushion is adapted to be folded about a fixed pivot shaft located near its lower forward edge and whose backrest is adapted to be folded about a fixed pivot shaft located near its lower edge in such a manner that these parts can be displaced out of the seating position into a position in which the back side of the backrest forms a horizontal loading surface which is delimited by the bottom side of the seat cushion as forward, vertical abutment surface; a shaft extending transversely to the driving direction is rotatably supported underneath the backrest and to the rear of the seat cushion whereby one lever each is non-rotatably arranged at the two ends of the shaft, which effect the seat cushion locking while a pivot arm is pivotally connected at the lever at a distance from the latter's pivot axis which, during actuation of the lever, is being disengaged from its detent.
