Abstract

A front-passenger airbag module includes a gas generator, a diffuser, a self-supporting airbag, and an airbag housing. To reduce the development costs of a new airbag system, a component system that includes the airbag, the diffuser, the gas generator, and an arched airbag holder, which is arranged between the airbag housing and the gas generator and which is at least partially enclosed by the lower section of the self-supporting airbag.

Claims

1. A front-passenger airbag module comprising:

a gas generator;

a diffuser;

an airbag;

an arched airbag holder; and

an airbag housing,

wherein at least a portion of airbag holder is arranged between the airbag housing and the gas generator, and wherein at least a portion of the airbag holder is enclosed by a lower section of the airbag.

2. The front-passenger airbag module as claimed in claim 1, wherein a diffuser chamber is provided between the diffuser and the arched airbag holder.

3. The front-passenger airbag module as claimed in claim 1, wherein the diffuser is arched shaped.

4. The front-passenger airbag module as claimed in claim 3, wherein the diffuser and the airbag holder take the form of cylindrical half-shells, and wherein the half-shells have flange-like edges that rest on one another in the assembled state.

5. The front-passenger airbag module as claimed in claim 1, wherein the gas generator is tubular, and wherein the airbag holder and the diffuser are open on at least one end for the introduction of the tubular gas generator.

6. The front-passenger airbag module as claimed claim 1, wherein, in an area outside the airbag holder, the airbag is situated between the diffuser and the gas generator.

7. The front-passenger airbag module as claimed in claim 1, further comprising:

fastening elements that fasten the component system to the airbag housing.

8. The front-passenger airbag module as claimed in claim 7, wherein the fastening elements depend from the diffuser and extend through the airbag housing.

9. The front-passenger airbag module as claimed in claim 1, further comprising:

fastening elements that fasten the diffuser to the airbag housing, wherein the fastening elements are threaded bolts.

10. The front-passenger airbag module as claimed in claim 9, wherein the threaded bolts depend from the diffuser and extend through the airbag housing.

11. The front-passenger airbag module as claimed in claim 1, wherein the diffuser has openings that are configured to serve as gas outlets.

12. The front-passenger airbag module as claimed in claim 1, wherein the diffuser has one or more flared scoops that are configured to serve as gas outlets and/or gas ducts.
