A reclining device includes: a reclining mechanism, which is capable of tilting of a seat back relative to a seat cushion to be locked or unlocked; a hinge pin, which is engaged with the reclining mechanism and configured to cause the reclining mechanism to be in an unlocked state; a first biasing member, one end of which is hooked to a hooking part provided at a seat-cushion-side member; and a second biasing member, one end of which is engaged to a periphery of an engagement part formed at the hinge pin and the other end of which is hooked to the seat-cushion-side member, wherein a vertical cross-section of the engagement part of the hinge pin has a non-circular shape.

Reclining device

A vehicle seat includes a bracket, a frame on which the bracket is installed, and a fixing member that is used for fixing the bracket and the frame. The bracket is provided with an engaging portion, the frame is provided with an engaged portion that is engageable with the engaging portion. By installing the fixing member to fix the bracket and the frame to each other, a state where at least a part of the engaging portion is inserted into the engaged portion or a state where at least a part of the engaged portion is inserted into the engaging portion is maintained while the bracket is elastically deformed.

Vehicle seat

A vehicle slide rail device is provided, which can reduce the possibility of the lock mechanism provided between the upper rail and the lower rail unintentionally lock-releasing when the cushion airbag is inflated. As a solution, the lock-release leveris provided with a lock-release contacting portion, which is positioned away from a press portionof the lock operational lever when the lock operational lever is positioned at a lock-allowing position and which receives a force from the press portion for rotating the lock release lever toward the unlocking position when the lock operational lever rotates from the lock-allowing position toward the lock-release position. When the upper railis deformed downwardly due to pressure by the inflating of a cushion airbag, the lock release lever moves downwardly together with a downwardly deforming portion of the upper rail and the lock-release contacting portion moves in a direction to closely approach the press portion of the lock operational lever.

Vehicular slide rail device

A storable vehicle seat is provided, which can be rotationally moved smoothly and can further be prevented from wobbling in a seating state even though the storable vehicle seat has a structure in which the rotational path of the seat is defined by front and rear links. An elongated support holeand a guide holeare formed in a seat cushion frame, a rotational support shaftwhich is rotatably engaged in the elongated support holeto be relatively movable therein and a guide projectionwhich is engaged in the guide holeto be movable therein are projected from an end of the front link, and an extension spring S is installed between the rotational support shaftand a locking projectionof the seat cushion frameto bias the rotational support shaftrearwardly.
