Abstract

A sliding armrest device for a vehicle may include a fixed armrest having a first oblique mounting surface formed on a top surface thereof and inclining along a width direction of a vehicle body, a sliding armrest having a second oblique mounting surface formed on an undersurface thereof and vertically matching the first oblique mounting surface, and a sliding rail device disposed between the first oblique mounting surface of the fixed armrest and the second oblique mounting surface of the sliding armrest and providing a forward and backward sliding force for the sliding armrest.

First claim

What is claimed is:

1. A sliding armrest device for a vehicle, comprising:
a fixed armrest having a first oblique mounting surface formed on a top surface thereof and inclining along a width direction of a vehicle body;
a sliding armrest having a second oblique mounting surface formed on an undersurface thereof and vertically matching the first oblique mounting surface; and
a sliding rail device disposed between the first oblique mounting surface of the fixed armrest and the second oblique mounting surface of the sliding armrest and providing a forward and backward sliding force for the sliding armrest,
wherein the sliding rail device comprises:
a fixed rail closely and fixedly mounted onto the first oblique mounting surface of the fixed armrest; and
a moving rail fixedly mounted onto the second oblique mounting surface of the sliding armrest and simultaneously attached slidably to the fixed rail.

2. The sliding armrest device of claim 1 , wherein the sliding rail device further comprises:
a retainer disposed between the fixed rail and the moving rail and having a plurality of ball holding apertures formed in both end portions thereof; and
a plurality of balls penetratively inserted into the ball holding apertures of the retainer and simultaneously disposed to roll between the fixed rail and the moving rail so as to provide a sliding transfer force for the moving rail with respect to the fixed rail.

3. The sliding armrest device of claim 1 , wherein the moving rail comprises an elastic pressurization end bent at both end portions thereof and covering an outer side surface of the ball.

4. The sliding armrest device of claim 1 , wherein the fixed rail comprises an elastic support end bent at both end portions thereof and covering an inner side surface of the ball.

5. The sliding armrest device of claim 1 , wherein in order to fix the fixed rail of the sliding rail device to the first oblique mounting surface of the fixed armrest, first assembly apertures for screw coupling are formed in the fixed rail and the first oblique mounting surface.

6. The sliding armrest device of claim 1 , wherein in order to fix the moving rail of the sliding rail device to the second oblique mounting surface of the sliding armrest, a tool insertion aperture is penetratively formed in the first oblique mounting surface and the fixed rail such that a tool is inserted into the tool insertion aperture from an undersurface of the fixed armrest, and a second assembly aperture for screw coupling is formed in the moving rail and the second oblique mounting surface so as to match the tool insertion aperture.

7. The sliding armrest device of claim 1 , further comprising an armrest cover member disposed over the sliding armrest and forming an armrest surface.

8. The sliding armrest device of claim 1 , wherein in order to fix the fixed rail of the sliding rail device to the first oblique mounting surface of the fixed armrest, first assembly apertures for screw coupling are formed in the fixed rail and the first oblique mounting surface.

9. The sliding armrest device of claim 1 , wherein in order to fix the moving rail of the sliding rail device to the second oblique mounting surface of the sliding armrest, a tool insertion aperture is penetratively formed in the first oblique mounting surface and the fixed rail such that a tool is inserted into the tool insertion aperture from an undersurface of the fixed armrest, and a second assembly aperture for screw coupling is formed in the moving rail and the second oblique mounting surface so as to match the tool insertion aperture.

10. The sliding armrest device of claim 1 , wherein the sliding armrest has a U-shaped section formed between inner side surfaces of the second oblique mounting surfaces of the sliding armrest.
