Abstract

A guide device is provided for guiding sliding movement of an armrest of a vehicle seat, the device comprising a guide rail, a sliding rail, and at least one slide, wherein the slide is arranged in an installed deformed state using a first spring element region formed on the slide and a second spring element region located a distance therefrom to contact an inner side of the sliding rail. A third spring element region is formed between the first and the second spring element regions interconnecting the first and second spring element regions. In the installed deformed state, the third region is formed in a curve at a distance from an inner side of the sliding rail and in the non-installed undeformed state, the third region is formed in a straight line.

First claim

What is claimed is:

1. A guide device for guiding a sliding movement of an armrest of a vehicle seat comprising:
a guide rail and a sliding rail arranged displaceably in a longitudinal adjustment direction relative thereto, at least one slide being able to be arranged without play between the guide rail and the sliding rail, wherein the at least one slide can be arranged in the installed, deformed state by means of at least one first spring element region which is arranged on the at least one slide and a second spring element region which is arranged at a distance therefrom so as to contact an inner side of the sliding rail, the first and the second spring element region being able to be arranged in a strip-like manner in the installed, deformed state and perpendicularly to the longitudinal adjustment direction in relation to the longitudinal extension thereof, a third spring element region of the at least one slide which is formed between the first and the second spring element region interconnecting the first and second spring element region and in the installed, deformed state, being formed in the manner of a curve at a distance from the inner side of the sliding rail, wherein the at least one slide is in the form of a C profile and one stop element is arranged on each outer side of the C profile on both sides of the first, second, and third spring element regions.

2. The guide device according to claim 1 , wherein inner sides of the C profile being able to be arranged so as to contact outer sides of the guide rail.

3. The guide device according to claim 2 , wherein the first, second, and third spring element regions are arranged on outer sides of the C profile.

4. The guide device according to claim 1 , wherein at least one load relief region in the form of a cutaway is formed on the at least one slide so as to be adjacent to the first, second, and third spring element regions.

5. The guide device according to claim 4 , wherein the cutaway is formed as a hollow space of the C profile.

6. The guide device according to claim 4 , wherein the cutaway is formed from a first rectangular portion with rounded corners and a second arc-shaped portion.

7. The guide device according to claim 1 , wherein the first, second, and third spring element regions have a declining spring characteristic.

8. The guide device according to claim 1 , wherein the at least one slide is formed in one piece.

9. The guide device according to claim 1 , wherein the at least one slide has a length from a range of from 20 to 28 mm.

10. The guide device according to claim 1 , wherein at least part of the inner side of the sliding rail is coated with an anti-friction coating.

11. The guide device according to claim 1 , wherein the at least one slide consists of plastics material.

12. The guide device according to claim 1 , wherein the at least one slide has a width from a range of from 6 to 12 mm.

13. The guide device according to claim 1 , wherein the at least one slide has a height from a range of from 6 to 10 mm.
