Abstract: In a locking device for a rear seat back cushion, a locking lever forms a constructional unit together with its shaft and a tension spring pretensioning it in the locking direction. During assembly, this unit is inserted from one end into a pit in a plastic component and is retained in the end position by means of snap lugs. The locking lever is unlocked by means of an actuation rod hitched onto it.

Abstract: A backrest for vehicle seats, especially for the rear seats of motor vehicles, includes a forwardly foldable center arm rest and a backrest support member arranged in back of the center arm rest. The back rest support member can be locked to the vehicle body structure and, after being released from its locking engagement with the vehicle body, can also be folded forwardly so that a space is created in the region of the center arm rest that can be utilized as a loading hatch. To effect locking of the backrest support member to the vehicle body, a latch pin is provided which has lateral abutment portions and which is fixedly secured rearwardly of the backrest support member to the vehicle body. The free end of the latch pin extends through an aperture of the backrest support member. The latch pin is adapted to receive a rotatable knob which is attached thereto from the front side of the backrest support member.
