By a contact of an engagement portion of a second memory member to a circumferential wall portion of a first memory member, the engagement portion is restricted from moving in a radial direction in accordance with a lock operation of lock members. By an engagement of the circumferential wall portion of the first memory member with the engagement portion of the second memory member that is in contact with the circumferential wall portion, the first memory member integrally rotates with a first rotary member on a same axis of the first and second rotary members. In a state where a rotation limiting mechanism restricts the first memory member and the first rotary member from integrally rotating with each other, the first memory member allows the engagement portion to slide along a longitudinal direction of the circumferential wall portion.

Seat slide apparatus for vehicle

A stopper includes an attachment portion and a pair of flanges. The attachment portion contacts an outer surface of a bottom wall portion of a lower rail and is attached to the bottom wall portion. The flanges extend from the attachment portion to be passed through insertion holes in the bottom wall portion. The flanges are located in an inner space of the lower rail. The flanges are engaged with second cut-and-raised pieces formed in an upper rail, thereby limiting the range of movement of the upper rail relative to the lower rail.

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 vehicle seat sliding apparatus having a lower rail adapted to be fixed to a vehicle floor and an upper rail adapted to be fixed to a seat and connected to the lower rail so as to be movable with respect to the lower rail includes: a lock lever adapted to be connected rotatably to the upper rail and engaged with the lower rail for selectively the movement of the upper rail with respect to the lower rail; an operating lever adapted to be connected rotatably to a supporting bracket adapted to support the seat in the direction of rotation different from the direction of rotation of the lock lever above the lock lever; and a connecting rod adapted to be connected at one end and the other end directly to the lock lever and the operating lever respectively, and adapted to transmit an operating force to release restriction of the movement with respect to the lock lever by a pressing operation in association with the rotation of the operating lever.

Vehicle seat sliding apparatus

A lower railhas a first cut-and-raised piece, and an upper railhas a second cut-and-raised piece. The first and second cut-and-raised pieceseach have a facing surfacethat faces and is contactable with the facing surface of the other cut-and-raised piece along the moving direction of the upper rail. The first and second cut-and-raised piecesare engaged with each other so as to limit the movement range of the upper railrelative to the lower rail. On the facing surfaceand the facing surface, inclination angles &#x3b1; and &#x3b2; are provided that generate a force causing the first and second cut-and-raised piecesto be more deeply engaged with each other, respectively. This prevents the first and second cut-and-raised piecesfrom being easily disengaged from each other.

The seat slide device further includes a memory piece detachably engaged with the lower rail and provided in a direction separating from the lower rail and engaging therewith when a seatback is reclined forward, wherein the memory piece is moved in association with the movement of the upper rail by retaining the memory piece at the receiving portion and the shaped portion when the memory piece is separated from the lower rail and wherein the memory piece is engaged with the lower rail at the engaging portion when the memory piece is engaged with the lower rail.

Seat slide device for vehicle

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.
