Abstract

An airbag for a motor vehicle includes a support structure moveable from a stowage position into a restraint position and a covering that surrounds a restraint volume of the airbag formed by the support structure in its restraint position. The covering is an element that is separate from the support structure and joined to the support structure.

Claims

1. An airbag for a motor vehicle, comprising:

a support structure configured to be moveable from a stowage position into a restraint position; and

a covering configured to surround a restraint volume of the airbag formed by the support structure in its restraint position,

wherein the covering is an element that is separate from the support structure and joined to the support structure,

wherein the support structure comprises a plurality of structural elements having variable volumes and having two textile layers, which are joined to each other in some regions, and

wherein the covering passes between the two textile layers of the support structure.

2. The airbag according to claim 1, wherein the restraint volume is at least predominantly surrounded by the covering.

3. The airbag according to claim 1, wherein the covering comprises a first air-permeable textile layer and at least one second film layer, the at least one second film layer covers at least some regions of the first layer and is joined thereto in some regions, some regions of the second film layer being impermeable to air and some regions being permeable to air entering the restraint volume in a first direction of flow and impermeable to air in a second direction of flow opposed to the first direction of flow.
