Abstract

An assembly consists of a backrest and an airbag module, the backrest having a frame, a padding and a covering part. The airbag module has an ejection channel that is attached to the frame. The covering part is designed so as to be rigid whereas the padding in an area of transition to the covering part is configured so as to be so pliant that by deformation of the padding a gap is produced between the covering part and the padding, for the airbag to come out of the backrest.

Claims

1. An assembly consisting of a backrest and an air bag module, said backrest having a frame, a padding and a covering part, and said air bag module having an air bag and an ejection channel that is attached to said frame, said padding lying against said covering part,

said covering part being designed so as to be rigid whereas said padding in an area of transition to said covering part is configured so as to be so pliant that by deformation of said padding a gap is produced between said covering part and said padding upon activation of said gas generator, for said air bag to come out of said backrest.

2. The assembly according to claim 1, wherein said gap is formed between said padding and said covering part in a side area of said backrest.

3. The assembly according to claim 2, wherein said ejection channel is configured so as to be curved, it extending starting from a rear side of said frame facing away from said padding toward said side area.

4. The assembly according to claim 1, wherein said padding has a slanted surface lying opposite said airbag module.

5. The assembly according to claim 1, wherein said airbag module has a gas lance that constitutes a connection to a gas generator.

6. The assembly according to claim 1, wherein the covering part is not bent or deflected by the air bag upon inflation.

7. An assembly consisting of a backrest and an air bag module, said backrest having a frame, a padding and a covering part, and said air bag module including an inflatable air bag and an ejection channel that is attached to said frame through which said air bag inflates, said padding lying against said covering part,

said covering part covering said air bag module and being rigid whereas said padding in an area of transition to said covering part is pliant, said air bag on inflation deforming said padding to produce a gap between said covering part and said padding upon activation of said gas generator, for said air bag to come out of said backrest.

8. The assembly according to claim 7, wherein the covering part is not bent or deflected by the air bag upon inflation.
