A left and a right stiffening bead is provided and located in an upper end region of the corresponding lateral border and in a portion of the main region a) that is directly adjacent the upper end region and that is b) in the neighborhood of the corresponding corner border.

Abstract: The vehicle seat has a seat carrier and an underframe. The underframe comprises two bottom rails, two seat rails, two front supports, and two rear pivoting supports. A buckle of a safety belt is provided. Tensile loads acting on the buckle are transferred into the underframe. The bottom rail neighboring the buckle is provided with a side part that extends upward toward the seat carrier. A slot is configured in this side part and is oriented substantially transversely to a direction of a force acting on the buckle during of a frontal crash. A sliding member is provided and is guided in the slot. A pull-type strap is arranged between the buckle and the sliding member. A connecting rod is arranged between the neighboring rear pivoting support and the sliding member. Whenever the seat carrier is adjusted in height, the neighboring rear pivoting support is pivoted and the connecting rod displaces the sliding member in the slot, causing the buckle to follow the movement of the seat carrier.

Abstract: A motor vehicle seat with a longitudinal guide that has a locking device. The seat has a backrest which has a release lever for tilting the seat forward. The operation of the release lever releases the backrest from a normally upright position and allows it to be tipped forward. The backrest is connected to the locking device of the longitudinal guide by means of a release mechanism so that when backrest is tipped forward, the locking device can be released and the motor vehicle seat can be moved manually in the longitudinal guide. Alternatively, if the backrest is in the upright position, the locking device is either ready to be operated, or in the process of operating. A memory device is provided for finding a position where the locking device was previously engaged following the longitudinal movement of the seat along the guide.
