Seat sliding apparatus for vehicle
A vehicle seat sliding apparatus includes a lower rail, an upper rail, a slide-lock mechanism that pivots the lock member to a slide-lock position and holds the upper rail in a slide-lock state, and a slide-lock cancellation unit moved by operation of an operation member in a longitudinal direction of the upper rail to cancel an action of the slide-lock mechanism. The slide-lock cancellation unit includes a drive unit and an inclined surface arranged in the drive unit. The drive unit is supported by the upper rail so as to be slidable in the longitudinal direction of the upper rail. Operation of the operation member slides the drive unit. The inclined surface pivots the lock member to a slide-lock cancellation position when sliding.
1. A vehicle seat sliding apparatus comprising:
a lower rail configured to be fixed to a floor of a vehicle;
an upper rail configured to be supported by the lower rail in a slidable manner, wherein a seat cushion is configured to be coupled to the upper rail;
a slide-lock mechanism located between the lower rail and the upper rail, wherein the slide-lock mechanism includes a spring member and a lock member, and the slide-lock mechanism pivots the lock member with a biasing force of the spring member to a slide-lock position and holds the upper rail in a slide-lock state; and
a slide-lock cancellation unit moved by operation of an operation member in a longitudinal direction of the upper rail to cancel an action of the slide-lock mechanism,
wherein the slide-lock cancellation unit includes
a drive unit supported by the upper rail so as to be slidable in the longitudinal direction of the upper rail based on operation of the operation member, and
a wedge arranged in the drive unit, wherein the wedge includes an inclined surface that pivots the lock member to a slide-lock cancellation position when sliding.
2. The vehicle seat sliding apparatus according to claim 1 , further comprising a cover member coupled to the upper rail, wherein
the cover member holds an upper surface of the drive unit in a slidable manner, and
the inclined surface downwardly presses and pivots a basal portion of the lock member when the drive unit slides.
3. The vehicle seat sliding apparatus according to claim 2 , wherein the drive unit including the wedge is formed from a synthetic resin.
4. The vehicle seat sliding apparatus according to claim 3 , wherein the wedge includes a horizontal surface that is continuous with the inclined surface.
5. The vehicle seat sliding apparatus according to claim 1 , further comprising a biasing member located between the drive unit and the upper rail,
wherein the biasing member is configured to move the wedge so that the lock member returns to a slide-lock position when pulling of a cable is cancelled.
