Abstract

A profile (9) which can be connected to a cover (4) serves to fasten the cover (4) on a supporting body (2). According to the invention, it is provided that the profile has a recess (17) for receiving a connecting region, in particular a seam (6), of cover segments (5.1, 5.2) of an at least two-piece cover.

Claims

1. An apparatus for attaching at least two distinct segments (5.1, 5.2) of a headrest cover connected at a seam (6) to a supporting body (2) comprising:

a profile (9) having a rectangular shaped cross section and a first section (A) in latching engagement with the supporting body (2) and a second section (B) immediately adjoining the first section (A) being affixed to one of the cover segments (5.2) and a third section (C) immediately adjoining the second section (B) in spaced relationship from the first section (A) wherein the third section (C) has a stepped first side surface (16′

, 16″

) defining a recess (17) of rectangular shape adjacent the supporting body (2) for receiving the seam (6) of the cover segments (5.1, 5.2) and wherein the third section (C) further includes an oblique surface (19) extending from the stepped first side surface (16′

, 16″

) to a second side surface (18) adjacent the supporting body (2) being curved along first and second radii (R₃, R₄) to define a gap between the profile (9) and the supporting body (2) for receiving one of the cover segments (5.2).

2. The apparatus of claim 1, further characterized in that the second section (B) is of thin-walled design in comparison to the first section (A) and the third section (C).

3. The apparatus of claim 2 wherein the rectangular cross section of the profile in the first section (A) provides a rotationally fixed latching connection between the profile (9) and the supporting body (2).

4. The apparatus of claim 3, further characterized in that the first section (A) is supported at least in two corner regions of a polygonal cross section of the channel (8).

5. The apparatus of claim 4, further characterized in that the first section (A) essentially fills the assigned region of the channel (8).

6. The apparatus of claim 2 wherein the third section (C) has a third side surface (16) extending between the first stepped side surface (16′

, 16″

) and the second section (B) and the second section (B) has a fourth side surface (11) in the same plane as the third side surface (16) and the first section (A) has a fifth side surface (12) in the same plane as the third side surface (16) and side surface (11).

7. The apparatus of claim 1, further characterized in that the third section (C) is provided with a region, which is arranged between the recess (17) and the second section (B), for deflecting the cover by an angle of 90°

to 130°

.

8. The apparatus of claim 1 further characterized in that the profile (9) is extruded from a foamed plastic.

9. A headrest (1) comprising:

a supporting body (2) having a peripheral edge defining a channel (8);

a cover (4) having at least two distinct segments (5.1, 5.2) joined together along a seam (6);

a profile (9) having a rectangular cross section and a first section (A) captured within the channel (8) of the supporting body (2) and a second section (B) immediately adjoining the first section (A) being affixable to one of the cover segments (5.2);

and characterized by said profile (9) including a third section (C) immediately adjoining the second section (B) in spaced relationship from the first section (A) wherein the third section (C) has a first stepped side surface (16′

, 16″

) defining a recess (17) of rectangular shape abutting the supporting body for receiving the seam (6) of the cover segments (5.1, 5.2) and wherein the third section (C) further includes an oblique surface (19) extending from the stepped first side surface (16′

, 16″

) to a second side surface (18) adjacent the supporting body (2) being curved along first and second radii (R₃, R₄) to define a gap between the profile (9) and the supporting body (2) for receiving one of the cover segments (5.2).

10. The headrest as in claim 9, further characterized in that the second section (B) is of thin-walled design in comparison to the first section (A) and the third section (C).

11. The headrest as in claim 10 wherein the rectangular cross section of the profile in the first section (A) provides a rotationally fixed connection in the channel (8).

12. The headrest as in claim 11 further characterized in that the first section (A) is supported at least in two corner regions of a polygonal cross section of the channel (8).

13. The headrest as in claim 12, further characterized in that the first section (A) essentially fills the assigned region of the channel (8).

14. The headrest as in claim 10 the third section (C) has a third side surface (16) extending between the first stepped side surface (16′

, 16″

) and the second section (B) and the second section (B) has a fourth side surface (11) in the same plane as the third side surface (16) and the first section (A) has a fifth side surface (12) in the same plane as the third side surface (16) and side surface (11).

15. The headrest as in claim 9, further characterized in that the third section (C) is provided with a region, which is arranged between the recess (17) and the second section (B), for deflecting the cover by an angle of 90°

to 130°

.

16. The headrest as in claim 9 further characterized in that the profile (9) is extruded from a foamed plastic.
