Hinge for an airbag cover
View Patent ↗The invention relates to a hinge for an airbag cover, having a planar textile element as a hinge between the cover of the airbag and an adjacent airbag cover region, for example in the interior of a motor vehicle, and to a region of the planar textile element which faces a carrier of the airbag cover and is embedded in a matrix which is connected to the cover, and a region of the planar textile element which is not embedded in the matrix.
1. A hinge for an airbag cover comprising:
an airbag-cover carrier;
an airbag cover that is attached to the airbag-cover carrier;
a matrix that is provided on the airbag-cover carrier; and
a two-dimensional textile element constructed as a folded element with fold crests on a first side and on a second side;
wherein the first side of the two-dimensional textile element is affixed to the airbag-cover carrier and the second side is affixable to an area near the airbag cover; and
wherein the first side is embedded in the matrix and the second side is not embedded in the matrix.
2. The hinge of claim 1 , wherein the matrix is constructed as a single piece together with the airbag-cover carrier.
3. The hinge according to claim 1 , wherein the matrix is constructed as a component separate from the airbag-cover carrier.
4. The hinge according to claim 1 , wherein the matrix is a hardened plastic material.
5. The hinge according to claim 1 , wherein a distance between the first side and the second side is a thickness dimension of the two-dimensional textile element and wherein the first side that is embedded in the matrix encompasses at least one-half of the thickness dimension.
6. The hinge according to claim 1 , wherein the two-dimensional textile element is a knitted fabric.
7. The hinge according to claim 1 , wherein the two-dimensional textile element is a woven fabric.
8. The hinge according to claim 1 , wherein the two-dimensional textile element is made of a synthetic material.
9. The hinge according to claim 1 , wherein the two-dimensional textile element is constructed of a stretch fabric.
10. The hinge according to claim 9 , wherein the stretch fabric stretches in multiple directions.
11. The hinge according to claim 1 , further comprising a flow-through resistance layer that is disposed between the airbag cover and the two-dimensional textile element, wherein the flow-through resistance layer has a higher flow-through resistance to molten material for forming the carrier than the two-dimensional textile element.
12. The hinge according to claim 11 , wherein the flow-through resistance layer is a component separate from the two-dimensional textile element.
13. The hinge according to claim 12 , wherein the flow-through resistance layer is a coating applied to the two-dimensional textile element.
14. The hinge according to claim 11 , wherein the flow-through resistance layer is connected to the two-dimensional textile element.
15. The hinge according to claim 11 , wherein the flow-through resistance layer is a fleece.
16. A hinge for an airbag cover comprising:
an airbag-cover carrier;
an airbag cover that is attached to the airbag-cover carrier;
a two-dimensional textile element having a first side that is affixed to the airbag-cover carrier and a second side that is affixable to an area near the airbag cover; and
a flow-through resistance layer that is disposed between the airbag cover and the two-dimensional textile element, wherein the flow-through resistance layer has a higher flow-through resistance to molten material for forming the carrier than the two-dimensional textile element.
17. The hinge according to claim 16 , wherein the flow-through resistance layer is a component separate from the two-dimensional textile element.
18. The hinge according to claim 16 , wherein the flow-through resistance layer is a coating applied to the two-dimensional textile element.
19. The hinge according to claim 16 , wherein the flow-through resistance layer is connected to the two-dimensional textile element.
