A vehicle seat sliding device includes: a first rail adapted to be fixed to one of a vehicle floor and a seat; a second rail adapted to be fixed to the other one of the vehicle floor and the seat, and coupled to the first rail in a relatively movable manner; an engagement member, which selectively limits and permits the relative movement of the first and the second rails; an operation member configured such that operating force to cancel the restriction of the relative movement in the second rail is transmitted to the engagement member; and a cover mounted on the first end of the second rail to close the first end. The cover has an engagement piece, which engages with a support wall provided in the second rail and restricts the pivoting of the cover when pressed against the operation member.

Vehicle seat sliding device

A vehicle seat sliding device includes: a lower rail adapted to be fixed to a vehicle floor; and an upper rail adapted to be fixed to a vehicle seat, and coupled with the lower rail in a relatively movable manner. A projection is arranged in the vicinity of the rear end portion of the lower rail, and protrudes above the bottom wall of the lower rail. A fitting recess is formed in the bottom wall more forward than the projection. A block body placed on the bottom wall extends to the projection and has a slanted surface more forward than the projection. The block body includes: a fitting protrusion, which fits into the fitting recess and positions the block body in the lateral direction; and a fitting wall, at least a part of which fits on the protrusion. The fitting wall positions the block body in the lateral direction.

A seat slide apparatus for a vehicle includes first and second lower rails, first and second upper rails, first and second lock levers, first and second biasing members, first and second support brackets fixed to the first and second upper rails and including first and second support portions, an operation handle including first and second power transmission portions pressing the first and second lock levers so as to release the restriction of the movement of the upper rails relative to the lower rails against a biasing force of the biasing members, and a release lever rotatably connected to the first upper rail and rotating in association with a forward folding of a seat back of the seat to release the restriction of the movement of the upper rails relative to the lower rails by directly pressing the first power transmission portion.

Seat slide apparatus for vehicle

A seat slide apparatus for a vehicle includes a first rail, a second rail slidably movable relative to the first rail, a lock member restricting a movement of the second rail relative to the first rail, a memory member movably supported within an inner void between the first rail and the second rail and prevented from moving, a first holding member holding the memory member so that the memory member is movable along with the second rail, a second holding member holding the memory member so as to maintain the engagement between the memory member and the first rail, a support bracket fixed to the second rail in the inner void and supporting one end portion of the second holding member, and a rail-side engagement portion arranged at the second rail, engaged with a holding-member-side engagement portion, and preventing the second holding member from being loosened from the second rail.

A seat slide apparatus for a vehicle includes a first rail, a second rail, a lock member, a memory member, a first holding member holding the memory member to move integrally with the second rail in a state where a restriction of the relative movement between the first rail and the second rail is released on a basis of an operation handle, and a second holding member holding the memory member so that the engagement of the memory member with the first rail is maintained in a state where the restriction of the relative movement is released in association with a forward folding operation of a seat back. The first holding member integrally includes a body portion and a memory member holding portion so as to sandwich the memory member in a state where the body portion engages with the front end portion of the memory member.

A seat slide apparatus for a vehicle includes a first rail, a second rail, a lock member, a plurality of engagement bores including a rear end engagement bore, a front end portion of the rear end engagement bore being further positioned in a forward direction than a rear end of the second rail in a state where the second rail is positioned at a foremost position, a rear end portion of the rear end engagement bore being exposed to a rear of the rear end of the second rail, a memory member, a holding member holding the memory member to move integrally with the second rail or holding the memory member to engage with one of the engagement bores, and an auxiliary bracket restricting a movement of the memory member that engages with the front end portion of the rear end engagement bore towards the rear end portion thereof.

A seat slide apparatus for a vehicle includes a first rail, a second rail slidably movable relative to the first rail, a lock member restricting a movement of the second rail relative to the first rail, a memory member movably supported within an inner void between the first rail and the second rail and prevented from moving, a holding member fixed to the second rail, holding the memory member so that the memory member is movable along with the second rail, and holding the memory member so as to maintain the engagement between the memory member and the first rail, a first stopper member positioned at one side of the memory member, and a second stopper member positioned at the other side of the memory member and preventing the second rail from moving in a condition where the memory member is sandwiched between the first and second stopper members.

In a vehicle seat sliding apparatus of the type wherein rotating an operating lever causes a lock lever to allow an upper rail to slide along a lower rail, the operating member is supported by a supporting bracket fixed to the upper rail to rotate about a fulcrum which is in the form of a plate of the bracket. The operating lever is provided with a slit into which a spring is fitted for being urged. The bracket also holds the spring. To avoid an engagement between the plate and the slit when the operating lever passes during an assembly of the apparatus, the plate is configured to incline relative to the slit.

Vehicle seat sliding apparatus

In a vehicle seat sliding apparatus including first and second rails, one of which is movable relative to the other within a range restricted by engagement between raised tabs of the first and second rails, a cover member is provided at an end of the upper rail. The cover extends into the upper rail along its lengthwise direction to reach a portion at which the raised tab of the upper rail. The cover is provided with an extension extending to the raised tab of the upper rail.

In a vehicle seat sliding apparatus wherein rotating an operating lever causes a lock lever to allow a sliding movement of an upper rail along a lower rail, the operating lever is held within a bracket connected to the upper rail via torsion spring. The torsion spring is made from a single piece of wire and formed into a specific shape for easy provision of the operating lever to the bracket during an assembly of the seat sliding apparatus.

A seat position adjusting apparatus for a vehicle includes a lower rail, an upper rail moved relatively with the lower rail, a locking mechanism restricting relative movement between the lower rail and the upper rail and releasing restriction on the relative movement, an operating member releasing restriction of the locking mechanism on the relative movement between the lower rail and the upper rail, a position memorizing mechanism for memorizing a position of the upper rail relative to the lower rail, a memorized position releasing member releasing the memorized position of the upper rail relative to the lower rail, wherein the position memorizing mechanism includes a movable member, an engaging member and a biasing member that has a first operating arm portion and a second operating arm portion that are positioned at two points on the engaging member with maintaining a predetermined distance therebetween in order to exert the operation force at the two points.
