Abstract
A seat slide device includes a handle rotatably supported in holding holes provided respectively at a pair of upper rails to rotate a radial projection portion for releasing a lock mechanism, and a bearing member having an outer edge portion disposed between the upper rail and the radial projection portion formed at the handle, a holding portion disposed between the upper rail and the outer periphery of the handle, and a cushioning portion allowing the handle to move in an axial direction. The bearing member is disposed to fit into the holding hole for supporting the handle.
Claims15
A seat slide device for a vehicle comprising:
- a lower rail adapted to be mounted on a vehicle floor;
- an upper rail adapted to be mounted on a vehicle seat and supported movably relative to the lower rail;
- a lock mechanism having:
- a lock portion disposed at one of the lower rail and the upper rail;
- and
- a lock member disposed at an other one of the lower rail and the upper rail, the lock member being engageable with or disengageable from the lock portion;
- a holding hole provided at the other one of the lower rail and the upper rail;
- a handle rotatably supported in the holding hole, the handle rotated to operate the lock member;
- a radial projection portion formed at the handle;
- and
- a bearing member fitting in the holding hole and supporting the handle, the bearing member having:
- an engaging portion which engages the handle to restrain axial movement of the handle relative to the bearing member;
- a holding portion holding the other one of the lower rail and the upper rail, the holding portion disposed between an outer peripheral portion of the handle and the other one of the lower rail and the upper rail, the holding portion including an outer edge portion disposed between the other one of the lower rail and the upper rail and the radial projection portion;
- and
- a cushioning portion allowing the handle, whose axial movement is restrained by the engaging portion, to move in an axial direction relative to the other one of the lower rail and the upper rail.

A seat slide device for a vehicle comprising:
- a pair of lower rails adapted to be mounted on a vehicle floor;
- a pair of upper rails adapted to be mounted on a vehicle seat and supported movably relative to the lower rail in a forward and backward direction on a plain surface of the rails;
- a lock mechanism having:
- a plurality of lock portions formed at each lower rail and arranged in parallel to each other along a longitudinal direction of the lower rail;
- and
- a lock member held on each upper rail, the lock member pivoted around a pivot axis extending in a longitudinal direction of the upper rail and being engageable with or disengageable from the plurality of lock portions,
- a pair of release levers, each moving the lock member to pivot and releasing engagement between the plurality of lock portions and the lock member;
- a handle being rotatable around a rotation axis extending in a lateral direction perpendicular to the longitudinal direction of the upper rail, the handle rotatably supported in holding holes provided at the pair of upper rails opposing to each other, the handle rotated to pivot the pair of release levers;
- and
- a pair of bearing members, each being formed with:
- a bearing hole rotatably supporting an end portion of the handle;
- a thrust bearing portion restraining an axial movement of the end portion;
- a fit holding portion fitted into a holding hole and restrained against a lateral movement;
- and
- a lateral cushioning portion permitting the thrust bearing portion to move in the lateral direction depending on variations in lateral distances between the end portions of the handle.
