Abstract

A draw-in bar for holding a cover of a vehicle seat on at least one latching receiving element, the draw-in bar having a profile body. The profile body has at least one first profile section with a basic cross section that is constant along a direction of longitudinal extent of the profile body and at least one second profile section with a safety cross section. The safety cross section projects beyond the basic cross section of the profile body in at least one transverse direction in the second profile section. A cover fastening system for a vehicle seat may have the latching receiving element and the draw-in bar where the draw-in bar is connectable to the latching receiving element by a latching connection.

First claim

What is claimed is:

1 . A draw-in bar for holding a cover of a vehicle seat on at least one latching receiving element connected to a foam part of the vehicle seat; the draw-in bar having a profile body, wherein the profile body has at least one first profile section with a basic cross section that is constant along a direction of longitudinal extent of the profile body,
wherein the profile body has at least one second profile section with a safety cross section, wherein the safety cross section projects beyond the basic cross section of the profile body in at least one transverse direction in the second profile section, wherein the safety cross-section blocks insertion of the at least one second profile section into the at least one latch receiving element.

2 . The draw-in bar according to claim 1 , wherein the profile body has a safety cross section in each of a plurality of second profile sections spaced apart from each other in the direction of longitudinal extent.

3 . The draw-in bar according to claim 1 , wherein the at least one safety cross section projects beyond the basic cross section in a first transverse direction, but corresponds to the basic cross section in a second transverse direction running perpendicularly to the first transverse direction.

4 . The draw-in bar according to claim 1 , wherein the at least one safety cross section of the profile body differs from the basic cross section on account of at least one material accumulation in the form of a projection.

5 . The draw-in bar according to claim 1 , wherein the draw-in bar has a seam tab which is connected to the profile body and is stitchable to a cover material of the cover.

6 . A cover fastening system, having a latching receiving element and a draw-in bar according to claim 1 , wherein the draw-in bar is connectable to the latching receiving element by a latching connection.

7 . The cover fastening system according to claim 6 , wherein the latching receiving element has a base and at least one latching tongue connected to the base and having at least one latching projection acting as a barb for the profile body.

8 . The cover fastening system according to claim 7 , wherein the latching receiving element has two latching tongues which are arranged and designed in such a way that the two latching tongues can be pushed apart by the profile body by pushing the profile body of the draw-in bar between the two latching tongues, as a result of which the latching projections of the latching tongues can be guided past the profile body and in this way a first profile section of the profile body, said first profile section having the basic cross section, can be inserted into an intermediate space between the latching tongues.

9 . The cover fastening system according to claim 8 , wherein the basic cross section of the profile body has a first width, the safety cross section of the profile body has a second width, and the intermediate space between the latching tongues has a third width, wherein the first width, the second width and the third width are matched to each other in such a way that the first profile section of the profile body, said first profile section having the basic cross section, is displaceable relative to the latching tongues in the direction of longitudinal extent until the second profile section having the safety cross section comes into interlocking contact with at least one of the latching tongues.

10 . A vehicle seat, having at least one foam part and at least one cover covering the at least one foam part, wherein the cover is connected to the at least one foam part by at least one cover fastening system according to ene of claim 6 .

11 . The vehicle seat of claim 10 , wherein sliding of the draw-in bar relative to the latching receiving element is prevented.

12 . The vehicle seat of claim 10 , wherein the profile body is configured to prevent a displacement in the direction of longitudinal extent.

13 . The vehicle seat of claim 10 , wherein in interaction with the latching receiving element, the profile body is configured to prevent a displacement in the longitudinal direction.

14 . The vehicle seat of claim 10 , wherein only the at least one first profile section of the draw-in bar is configured to slide within the latching receiving element.

15 . The vehicle seat of claim 10 , wherein after a limited relative displacement between the first profile section and the latching receiving element, the draw-in bar is secured against further displacement in the latching receiving element by the safety cross section.

16 . The vehicle seat of claim 10 , wherein a width of the safety cross section prevents passage of the at least one second profile section through the latching receiving element.

17 . The vehicle seat of claim 10 , wherein the latching receiving element comprises two latching tongues with an intermediate space between the two latching tongues,
wherein the first profile section is displaceable in the intermediate space between the latching tongues, wherein the second profile section is not insertable into the intermediate space between the latching tongues.
