Abstract: A seat recliner includes a disk-shaped outer case provided with a ring-shaped protrusion that is formed along a circumference thereof and is protruded in a thickness direction thereof, a disk-shaped inner case provided inside the ring-shaped protrusion rotatably in a circumferential direction thereof, a ring-shaped holder covering outer circumferential surfaces of the outer and inner cases to restrict displacement of the inner case so as to be distanced from the outer case, and an escape portion formed by depressing one of an opening edge portion on an inner circumferential surface of the ring-shaped protrusion and a portion, on an outer circumferential surface of the inner case, facing to the opening edge portion to be distanced from another of the opening edge portion and the portion facing to the opening edge portion.

Abstract: A latch plate for a lock device is proposed which comprises a latch plate proper and a film that covers the latch plate proper. The latch plate proper includes upper and lower finger portions between which a striker catching recess is defined. An upper surface of the lower finger portion includes a depressed main portion located near the bottom of the striker catching recess, a raised leading end portion and a stepped portion provided between the depressed main portion and the raised leading end portion. The film covers the latch plate proper except the raised leading end portion. The film covers the depressed main portion of the upper surface in such a manner that an outer surface of the film is flush with the stepped portion. When the film is depressed by the striker, the stepped portion enhances a function is to stop a movement of the striker toward a mouth of the striker catching recess.

Abstract: A seat lock device comprises a base plate having a striker receiving recess for receiving a striker, a latch plate having a striker receiving recess and rotatably connected to the base plate and rotatable between latch and unlatch positions with respect to the striker, a lock plate rotatably connected to the base plate and rotatable between lock and unlock positions with respect to the latch plate and a cover member having a U-shaped flange formed thereon and covering one major surface of the base plate having the U-shaped flange neatly disposed on a peripheral edge of the striker receiving recess. The seat lock device further comprises pawls provided by the base plate and depressed toward the cover member, recesses provided by the cover member for receiving the pawls respectively and stoppers provided by respective walls of the recesses for preventing the pawls from being disengaged from the recesses.

Abstract: A lock device for a vehicular seat, including a striker and a catcher including a base plate, a cover, a first striker receiving portion formed in each of the base plate and the cover, a latch rotatably disposed through a latch shaft, a lock plate rotatably disposed through a lock shaft, and a rubber bumper mounted to the first striker receiving portion of the base plate. The rubber bumper includes engaging grooves engaged with side peripheries of the first striker receiving portion of the base plate, respectively, a recessed portion engaged with a bumper receiving portion formed on a bottom surface of the first striker receiving portion of the base plate, and restraining portions engageable with outer circumferential surfaces of the latch shaft and the lock shaft, thereby restraining the rubber bumper from falling off from the first striker receiving portion of the base plate.
