Abstract

PURPOSE:To enable a lock to be released and a seat back to be brought down forward with a bushing member disposed in a trunk room, by connecting pivotably a lock piece engageable with a striker to the seat back and providing a rod adjacent the trunk room in said lock piece. CONSTITUTION:When a strap 17 mounted on a lock lever 16 is pulled from the front a lock piece 13 is pivoted counterclockwise against a spring 15 about a shaft 11 erected on a base frame 10 fixed to the upper portion of a back reclining plate portion 7 and disengaged from a striker 14, while the back reclining plate portion 7 is brought down forward as it is by a tensile force. On the other hand, when a knob 35 is pushed from a trunk room 30 against a spring 36, a bushing portion 32 moves to push a bed seat 22 provided on the rear end 21 of a rod 20 so that the lock piece 13 is rotated about the shaft 11 to be disengaged from the striker 14. And a pin 24 interferes with an end of a notch 23 if the lock piece 13 to stop the rotation of the lock piece 13 and a seat back 3 is rotated in the direction of falling down forward by a press force.

d0 Means for Solving Problems In order to achieve this purpose, a seat back which is provided to be able to tilt back and forth from an upright position with respect to the vehicle body is held in a locked state by a locking device in an upright position. In the locking device for a five-socket rear trunk for an automobile, the locking device is rotatably supported on the upper part of the seat back, and is connected to a lock piece that is removable to a striker through the vehicle body to a trunk room. A bushing member arranged on the trunk side of the vehicle body locks off the locking piece and allows the seat back to be pushed forward.
