Seat sliding device and assembling method of lock spring used in seat sliding device

The present disclosure discloses one example of a one-way coupling that eliminates the need for a component corresponding to a guide piece. The one-way coupling of the present discloser includes an input shaft and an output shaft, and is configured to transmit a drive force from the input shaft to the output shaft, and inhibit the drive force inputted to the output shaft from being transmitted to the input shaft. The one-way coupling includes: a transmitter; an immovable ring; a pressure-contact cam; a first wedge member displaceable between a locked position and an unlocked position, and receiving a pressing force from the pressure-contact cam when the drive force is inputted to the input shaft, and thereby the first wedge member is displaced to the locked position; and a first holder holding an arrangement of the first wedge member when the drive force is inputted to the output shaft.

One-way coupling

A sliding device includes a fixed rail, a movable rail, a lock plate, a spring member, and a first stopper and a second stopper provided on the lock plate. The lock plate is held by the movable rail, and is displaceable between a locking position where the lock plate engages with the fixed rail and a non-locking position where the engagement is released. The spring member can exert an elastic force to maintain the lock plate in the locking position. The first stopper locks and fixes a first end of the lock plate to the spring member. The second stopper locks and fixes a second end of the lock plate to the spring member.

A sliding device includes a fixed rail, a movable rail, a lock plate, and a spring member. A seat body is fixed to the movable rail, and the movable rail is slidable relative to the fixed rail. The lock plate is held by the movable rail, and is displaceable between a locking position where the lock plate engages with the fixed rail and restricts slide of the movable rail and a non-locking position where the restriction is released. The spring member exerts an elastic force to maintain the lock plate in the locking position.

A sliding device includes a fixed rail, a movable rail, a lock plate, a spring member, and a fixing structure. The lock plate is displaced between a locking position where the lock plate engages with the fixed rail and restricts slide of the movable rail and a non-locking position where the restriction of slide is released. The spring member exerts an elastic force to maintain the lock plate in the locking position. The fixing structure includes a tapered portion of the spring member and a press spring portion that presses the tapered portion toward a hole of the movable rail.

A releasing lever for a sliding device in one aspect of the present disclosure is used for the sliding device including a movable rail and a fixed rail. The releasing lever includes a first protrusion and a second protrusion. The first protrusion is formed in an intermediate portion of the releasing lever and protrudes in an abutting direction on a first end of the intermediate portion. The second protrusion is formed in a position offset from the first protrusion toward a second end of the intermediate portion, and protrudes in the abutting direction. The first protrusion and the second protrusion contact an inside wall surface of the movable rail at least when the releasing lever pivots.

Releasing lever for sliding device

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, and a releasing member. The lock portion is displaceable between a restraint position and a release position. The elastically deforming portion comprises: a linear portion that is an elastically deformable portion extending in a direction approximately parallel to a longitudinal direction of the movable-side rail; and an engaging portion protruding from an extending-direction leading end portion of the linear portion in a direction approximately perpendicular to an extending direction of the linear portion. The releasing member comprises: a first engaged surface that is contactable with the engaging portion from one end side in the extending direction; and a second engaged surface that is contactable with the engaging portion from the other end side in the extending-direction.

Seat sliding device

Provided is a sliding device that allows two release levers to operate in a synchronous manner. The sliding device includes a lock portion that is displaceable between a locking position and a non-locking position; a release lever configured to be displaced by an operating force; an operation portion provided at a first end of the release lever in an extending direction thereof to receive the operating force; an action portion provided at a second end of the release lever in the extending direction thereof to transmit the operating force to the lock portion via the release lever; and an operating lever provided to the movable rail and displaceable between an operating position to apply the operating force to the operation portion and a non-operating position to apply no operating force to the operation portion.

Provided is a sliding device for a vehicle seat. The device includes a fixed rail, a movable rail, a lock portion, an operating lever, a first locking protrusion, and a lock lever. When a first contact surface among side faces of the first locking protrusion and a second contact surface among side faces of a second locking protrusion of the lock lever are in contact with each other, the operating lever is retained in one of a first position or a second position, and when a protruding-direction end of the first locking protrusion and a protruding-direction end of the second locking protrusion are in contact with each other, the operating lever is retained in the other of the first position or the second position.

Return mechanism including lock lever with locking protrusion

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, a releasing member, and a restricting portion. The movable-side rail comprises an open-sectional portion including two side walls and a lid wall. The lock portion is displaceable between a restraint position and a release position. The releasing member is provided between the elastically deforming portion and the lid wall. The restricting portion is configured to provide a space through which an insertion-side end of the releasing member is insertable between the elastically deforming portion and the lid wall.

Provided is a seat sliding device that includes a fixed rail, a movable rail, a first latch, a second latch, and a third latch. The first latch serves as a main lock. The second latch is positioned a distance from the first latch along a longitudinal axis of the fixed rail, and the third latch is positioned a distance from the first latch along the longitudinal axis.

A seat slide device for vehicles includes a lower rail, an upper rail, a lock mechanism, a spring member, and an unlocking handle. The upper rail is supported in a slidable manner by the lower rail. The lock mechanism is provided within the upper rail and restricts the movement of the upper rail relative to the lower rail. The spring member is provided within the upper rail. The unlocking handle is operated against the pressing force of the spring member to remove restrictions on the movement of the upper rail imposed by the lock mechanism. The upper rail has inner walls and outer walls. The inner walls have engagement holes formed through the inner walls in the width direction. The spring member has engagement sections inserted through and engaged with the engagement holes. The engagement sections face the outer walls in the width direction.
