Abstract
An airbag arrangement comprising a flap, which closes a passage opening for an airbag, a hinge section along a side of the flap, an chute wall, which is connected to the flap via the hinge section; and a material web, which is partially arranged in the flap and partially in the chute wall, and transverses the hinge section, wherein the material web is molded into the chute wall and is anchored in the material of the chute wall.
Claims20
An airbag arrangement comprising:
- a flap component, which closes a passage opening for an airbag;
- a hinge section along one side of the flap component;
- a chute component, which is connected to the flap component via the hinge section;
- and
- a material web, which is partially arranged in the flap component and partially in the chute component, and transverses the hinge section;
- wherein the material web is molded into the chute component and is anchored in material of the chute component;
- wherein the chute component forms at least one wall of an airbag chute, the wall having a length extending away from the flap component and terminating in a distal end;
- wherein the material web includes a first part that forms a surface of said flap component and a second part that is arranged on an inner side of the wall from the hinge section for a first distance of the length of the wall, and the material web includes a third part arranged on an outer side of the wall for a second distance of the length of the wall, and wherein the material web penetrates the wall between the material web arranged on the inner side of the wall and the material web arranged on the outer side of the wall;
- wherein the material web has a first side, a second side opposite the first side, and a thickness defined between the first side and the second side;
- wherein the first side of the material web is arranged on the inner side of the wall, and the first side or the second side of the material web is arranged on the outer side of the wall;
- wherein the material web has an edgefolding between said second and third part of said material web, which is embedded into the wall such that the material web abuts on the inner side of the wall on a first side of the edgefolding and the material web abuts on the outer side of the wall on a second side of the edgefolding
- wherein said embedded edgefolding defines an acute angle between said second and third part of said material web.

A method for manufacturing an airbag arrangement, comprising:
- providing a mold comprising a first mold shell and a second mold shell, which are configured to integrally form a flap component, which closes a passage opening for an airbag, a hinge section along a side of the flap component, and a chute component, which is connected to the flap component via the hinge section;
- placing a material web into the mold having a first part which is configured to form a surface of the flap component, which faces the airbag, a second part which is configured to form an adjoining surface of the chute component which adjoins the surface of the flap component, and a third part which is configured to form an opposite surface of the chute component which is opposite the adjoining surface;
- closing the mold;
- introducing plastic material into the closed mold;
- wherein the material web, placed into the mold, has an edgefolding between the second and the third part of the material web, into which the plastic material penetrates, wherein the penetrating plastic material pushes apart the second and the third part of the material web and against the opposite surfaces of the mold.
