Abstract

Claims (15)

1 . An end cap for a rail of a longitudinal adjuster, wherein the end cap has a covering portion, for covering an end-face end of the rail, and a fastening portion, for fastening the end cap to the rail, wherein the fastening portion is connected to the covering portion through a four-joint coupling mechanism, wherein the four-joint coupling mechanism is defined by a frame, a first link, a second link and the fastening portion which connects the first link and the second link to one another.

2 . The end cap as claimed in claim 1 , wherein an upper connecting point of the first link to the frame defines a first point of articulation.

3 . The end cap as claimed in claim 2 , wherein a lower connecting point of the second link to the frame defines a second point of articulation.

4 . The end cap as claimed in claim 3 , wherein an upper connecting point of the fastening portion to the first link defines a third point of articulation.

5 . The end cap as claimed in claim 4 , wherein a lower connecting point of the fastening portion to the second link defines a fourth point of articulation.

6 . The end cap as claimed in claim 1 , wherein an upper connecting point of the fastening portion is connected to the covering portion by the first link.

7 . The end cap as claimed in claim 1 , wherein a lower connecting point of the fastening portion is connected to the covering portion by the second link.

8 . The end cap as claimed in claim 1 , wherein the frame is defined by the covering portion.

9 . The end cap as claimed in claim 1 , wherein the end cap is elastically deformable at least in sections.

10 . The end cap as claimed in claim 1 , wherein a fastening point is part of the fastening portion of the end cap.

11 . The end cap as claimed in claim 10 , wherein, in a region of the fastening point, a protrusion protrudes laterally, including parallel to a transverse direction, said protrusion being able to be brought into contact with an edge region of an opening of the first rail.

12 . The end cap as claimed in claim 11 , wherein the protrusion has a curved contour extending towards the covering portion of the end cap.

13 . A longitudinal adjuster for a vehicle seat, having at least one pair of rails which is formed from a first rail and a second rail guided displaceably in the longitudinal direction relative to the first rail, wherein at least the first rail or the second rail has at least one opening for the fastening of an end cap for an end of either the first rail or the second rail, wherein the longitudinal adjuster has the end cap of claim 1 .

14 . The longitudinal adjuster as claimed in claim 13 , wherein an edge region of the opening has an arched contour.

15 . An end cap for a rail of a longitudinal adjuster, wherein the end cap has a covering portion, for covering an end-face end of the rail, and a fastening portion, for fastening the end cap to the rail, wherein the fastening portion is connected to the covering portion with A formation of a coupling mechanism, wherein an upper connecting point of A first link to a frame defines a first point of articulation, wherein a lower connecting point of A second link to the frame defines a second point of articulation, and wherein an upper connecting point of the fastening portion to the first link defines a third point of articulation.
