Airbag
First Claim
1. An airbag for an airbag module of a motor vehicle, the airbag being inflated to cushion a person in the event of a collision by filling with gas, comprises:
- an inner chamber enclosed by an inner covering, the inner chamber forming an inner region of the airbag when inflated;
a plurality of outer chambers that are arranged outside the inner chamber, the outer chambers at least partially surrounding the inner chamber when inflated; and
a gas generator to provide gas to inflate the airbag,wherein the outer chambers are in fluid communication with the inner chamber,wherein the outer chambers do not have inflow openings for direct inflow of gas from a gas generator, but are in fluid communication with the inner chamber in such a manner that the outer chambers are configured to be inflated exclusively with gas from the inner chamber,wherein at least some of the outer chambers are each enclosed by an outer covering having a covering section opposite the inner covering that does not delimit the inner chamber, andwherein the covering sections are at least partially spaced apart from the inner covering so that at least one clearance not filled with gas when the airbag is inflated is formed between the inner covering and the opposing covering sections.

Abstract
An airbag module including an airbag that is inflated to cushion a vehicle occupant in the event of a collision. The airbag includes an inner chamber enclosed by an inner covering and a plurality of outer chambers that are arranged outside the inner chamber. The inner chamber forms an inner region of the airbag when inflated and the outer chambers at least partially surround the inner chamber when inflated. The outer chambers are in fluid communication with the inner chamber. At least some of the outer chambers are each enclosed by an outer covering having a covering section opposite the inner covering that does not delimit the inner chamber. The covering sections are at least partially spaced apart from the inner covering so that at least one clearance not filled with gas when the airbag is inflated is formed between the inner covering and the opposing covering sections.
