First Claim
Patent Images
1. An airbag for an occupant protection device of a vehicle, comprising:
- at least one supporting chamber for providing mechanical stability in the inflated state, and at least one energy absorption chamber associated with the at least one supporting member; and
wherein the at least one energy absorption chamber is more gas permeable than the supporting chamber; and
wherein the at least one energy absorption chamber is configured to absorb more energy than the supporting chamber during a first phase of an accident.

Abstract
The disclosed airbag is for an occupant protection device, which protects a vehicle occupant in the event of an accident. In order for the airbag to provide a vehicle occupant with a great protective effect, an embodiment may comprise at least one supporting chamber, which gives the airbag mechanical stability in the inflated state, and at least one energy absorption chamber, which is designed to be more gas permeable than the supporting chamber. With such a configurations the energy absorption chamber absorbs more energy than the supporting chamber during the first phase of an accident.

8. A airbag for an occupant protection device of a vehicle, comprising:
-
a first material layer, and a second material layer connected to the first layer;
wherein the two connected material layers are folded along a fold line and are folded onto each other in such a manner that the first material layer lies on the outside and the second material layer lies on the inside;
wherein an energy absorption chamber is bounded by mutually opposite sections of the second material layer lying on the inside, and wherein at least two supporting chambers are bounded by mutually opposite sections of the first and second material layers. - View Dependent Claims (9, 10, 11, 12, 13)
