Abstract

A cover feed-through (B), for a head-restraint rod ( 5 ) of a head restraint for a vehicle seat, is configured as a one-piece self-securing guide element ( 1 ). The guide element has a closed upper face ( 2 ) and a lower face ( 4 ) which is spaced from the upper face by a passage ( 3 ). The lower face ( 4 ) has at least one opening ( 4.1 ) substantially in the form of a segment of a circle. A vehicle seat is also provided, including a cover ( 8 ) and a head-restraint which can be arranged in a cover feed-through (B).

First claim

1 . A cover feed-through for a head-restraint rod ( 5 ) of a head restraint of a vehicle seat, the cover feed-through comprising a single-part, self-fixing guide element comprising: a closed upper side; a lower side; and a passage defining portion, the upper side, and the lower side being spaced apart from each other by the passage defining portion, wherein the lower side has at least one recess in the shape of a segment of a circle.

2 . The cover feed-through as claimed in claim 1 , wherein the self-fixing guide element has a circular configuration.

3 . The cover feed-through as claimed in claim 1 , wherein a radial gap is arranged in an encircling manner between the upper side and the lower side.

4 . The cover feed-through as claimed in claim 1 , wherein at least two elastically deformable ribs are arranged opposite each other and are formed radially inwards from an inner side of the passage defining portion.

5 . The cover feed-through as claimed in claim 1 , wherein at least one undercut is arranged on an inner side of the passage defining portion.

6 . The cover feed-through as claimed in claim 1 , wherein at least one support runs radially outward on an surface of the lower side.

7 . The cover feed-through as claimed in claim 1 , further comprising at least one orientation element.

8 . A vehicle seat comprising:
a cover and a head restraint comprising a head restraint rod, into which a cover feed-through is disposable, the cover feed-through comprising a single-part, self-fixing guide element comprising: a closed upper side; a lower side; and a passage defining portion, the upper side and the lower side being spaced apart from each other by the passage defining portion, wherein the lower side has at least one recess in a shape of a segment of a circle.

9 . The vehicle seat as claimed in claim 8 , wherein the cover has a through opening from which a slot extends radially outward.

10 . The vehicle seat as claimed in claim 8 , wherein the self-fixing guide element has a circular configuration.

11 . The vehicle seat as claimed in claim 8 , wherein a radial gap is arranged in an encircling manner between the upper side and the lower side.

12 . The vehicle seat as claimed in claim 8 , wherein at least two elastically deformable ribs are arranged opposite each other and are formed radially inwards from an inner side of the passage defining portion.

13 . The vehicle seat as claimed in claim 8 , wherein at least one undercut is arranged on an inner side of the passage defining portion.

14 . The vehicle seat as claimed in claim 8 , wherein at least one support runs radially outward on an surface of the lower side.
