Sliding device
One example of a sliding device that can sufficiently reduce a separation phenomenon is disclosed. The sliding device includes a fixed rail, a movable rail, a fixed-side hook, an engagement hook, and a reinforcing hook. The fixed rail is configured to be fixed to a vehicle. To the movable rail, the seat body is attachable. The movable rail is slidable with respect to the fixed rail. The fixed-side hook is configured to be fixed to the vehicle. The engagement hook is provided to the movable rail. The engagement hook is engageable with the fixed-side hook, and is formed by a first plate material curved approximately into a letter J or U shape. The reinforcing hook overlaps with the engagement hook in a thickness direction of the first plate material. The reinforcing hook is formed by a second plate material curved approximately into a letter J or U shape.
1. A sliding device configured to support a seat body of a vehicle seat in a slidable manner, the sliding device comprising:
a fixed rail configured to be fixed to a vehicle;
a movable rail to which the seat body is attachable, the movable rail being slidable with respect to the fixed rail;
a fixed-side hook configured to be fixed to the fixed rail;
an engagement hook provided to the movable rail so as to be engageable with the fixed-side hook, the engagement hook including a first plate material curved approximately into a letter J shape or approximately into a letter U shape;
a reinforcing hook overlapping with the engagement hook in a thickness direction of the first plate material, the reinforcing hook including a second plate material curved approximately into a letter J shape or approximately into a letter U shape, and
a coupling member configured to penetrate the movable rail or the engagement hook, penetrate the reinforcing hook, and couple the movable rail or the engagement hook with the reinforcing hook; and a clamp provided to the movable rail and configured to fasten and secure the seat body, wherein the coupling member is disposed in a position closer to the clamp than to a distal end of the engagement hook.
2. The sliding device according to claim 1 , wherein the distal end of the engagement hook and a distal end of the reinforcing hook are welded.
3. The sliding device according to claim 2 further comprising a step portion formed by the distal end of the engagement hook and the distal end of the reinforcing hook.
4. The sliding device according to claim 1 further comprising at least one roller that makes the movable rail slidable with respect to the fixed rail,
wherein the movable rail comprises at least one roller bracket supporting the at least one roller, and
wherein the reinforcing hook is integrated with the at least one roller bracket.
5. The sliding device according to claim 1 , wherein the reinforcing hook is located at an end of the movable rail in a sliding direction.
6. The sliding device according to claim 5 , wherein the engagement hook is located at the end of the movable rail in the sliding direction.
