Abstract

A composite component ( 110 ) for a vehicle seat ( 1 ), in particular for a motor vehicle seat, includes a plurality of fabric layers ( 116 ) of a fibrous material, a matrix material ( 118 ) securing the fabric layers ( 116 ), and an insert part ( 140 ), disposed between at least two of the fabric layers ( 116 ), for locally reinforcing the composite component. An insert strand ( 150 ) is disposed at least in sections along an edge or an edge surface ( 141.1 ) of the insert part ( 140 ). A vehicle seat ( 1 ) includes the composite component, in particular with a back structure ( 110 ) designed as a composite component.

First claim

The invention claimed is:

1. A composite component for a motor vehicle seat, the composite component comprising:
a plurality of woven fabric layers formed of a fibrous material;
a matrix material securing the woven fabric layers;
an insert part arranged between at least two of the woven fabric layers, for locally reinforcing the composite component; and
an insert strand arranged at least in sections along an edge or an edge surface of the insert part, wherein a surface side of the insert part is covered by a first layer of the woven fabric layers and matrix material, and a further surface side of the insert part is covered by a second layer of the woven fabric layers and matrix material.

2. The composite component as claimed in claim 1 , wherein the insert part is not covered by the woven fabric layers and matrix material in a not covered region.

3. The composite component as claimed in claim 2 , wherein the insert part has at least one threaded bushing with an internal thread for the screwing on of an additional component, and the not covered region, at which the insert part is not covered by woven fabric layers and matrix material, is a region of the threaded busing.

4. The composite component as claimed in claim 1 , wherein the insert strand is an elongate profile.

5. The composite component as claimed in claim 4 , wherein the insert strand has a constant cross section over an entire profile length.

6. The composite component as claimed in claim 1 , wherein the cross section of the insert strand is approximately triangular wedge shaped.

7. The composite component as claimed in claim 1 , wherein a cross section of the insert strand has rounded corners.

8. The composite component as claimed in claim 1 , wherein material of the insert strand has a lower strength than material of the woven fabric layers or than the matrix material or than both the material of the woven fabric layers and the matrix material.

9. The composite component as claimed in claim 1 , wherein the insert strand comprises glass fibers and the woven fabric layers comprise carbon.

10. The composite component as claimed in claim 1 , wherein the insert strand is a rubber band or a plastics band.

11. The composite component as claimed in claim 1 , wherein the insert part is formed as a punched part made of metal.

12. The composite component as claimed in claim 11 , wherein the insert part is formed from steel.

13. The composite component as claimed in claim 1 , wherein the composite component is configured as a backrest structure for a vehicle seat or as part of a backrest structure for a vehicle seat and the insert part connects the backrest structure to a fitting.

14. A motor vehicle seat comprising a composite component of a backrest structure the composite component comprising:
a plurality of woven fabric layers formed of a fibrous material;
a matrix material securing the woven fabric layers;
an insert part arranged between at least two of the woven fabric layers, for locally reinforcing the composite component; and
an insert strand arranged at least in sections along an edge or an edge surface of the insert part, wherein the insert part has at least one threaded bushing with an internal thread for screwing on of an additional component, and a not covered region, at which the insert part is not covered by woven fabric layers and matrix material, is a region of the threaded bushing.

15. The vehicle seat according to claim 14 , wherein a surface side of the insert part is covered by a first layer of the woven fabric layers and matrix material, and a further surface side of the insert part is covered by a second layer of the woven fabric layers and matrix material.

16. The vehicle seat according to claim 14 , wherein:
the insert strand is an elongate profile with an essentially constant cross section over an entire profile length; and
the insert part is formed as a punched part made of metal.

17. The vehicle seat according to claim 14 , further comprising a fitting, wherein the insert part connects the backrest structure to the fitting.

18. A composite component for a motor vehicle seat, the composite component comprising:
a plurality of woven fabric layers formed of a fibrous material;
a matrix material securing the woven fabric layers;
an insert part arranged between at least two if the woven fabrics layers, for locally reinforcing the composite component; and
an insert strand arranged at least in sections along an edge or an edge of the insert part, wherein material of the insert strand has a lower strength than material of the woven fabric layers or than the matrix material or than both the material of the woven fabric layers and the matrix material.
