Abstract

An airbag module (10; 110) for a vehicle occupant restraint system comprises a gas lance (22; 122) that can feed gas from a source of compressed gas (40; 140) into an airbag (20; 120), and a housing (12; 112) which accommodates the gas lance. The gas lance (22; 122) has a connection extension (36; 136) for being connected to the source of compressed gas (40; 140). The connection extension (36; 136) projects so far out of the housing (12; 112) that it can penetrate into the source of compressed gas (40; 140) installed outside of the housing. The connection extension serves to supply the gas lance (22; 122) with compressed gas from the source of compressed gas (40; 140) as well as to mechanically attach the source of compressed gas (40; 140) to the airbag module (10; 110).

Claims

1. An airbag module (10;

110) for a vehicle occupant restraint system, said airbag module comprising a gas lance (22;

122) that can feed gas from a source of compressed gas (40;

140) into an airbag (20;

120), and a housing (12;

112) which accommodates said gas lance, said gas lance (22;

122) having a connection extension (36;

136) for being connected to said source of compressed gas (40;

140), characterized in that said connection extension (36;

136) projects so far out of said housing (12;

112) that it can penetrate into said source of compressed gas (40;

140) installed outside of said housing and it serves to supply said gas lance (22;

122) with compressed gas from said source of compressed gas (40;

140) as well as to mechanically attach said source of compressed gas (40;

140) to said airbag module (10;

110).

2. The airbag module according to claim 1, characterized in that said connection extension (36;

136) projects so far out of said housing (12;

112) that it can penetrate right through said source of compressed gas (40;

140) installed outside of said housing.

3. The airbag module according to claim 1, characterized in that said connection extension (36;

136) has two ends and is provided with a thread on one of said ends (56;

156) which faces away from said gas lance (22;

122).

4. The airbag module according to claim 1, characterized in that said gas lance (22;

122) is T-shaped in an area of said connection extension (36;

136).

5. The airbag module according to claim 1, characterized in that said housing is configured as an extruded profile.

6. The airbag module according to claim 1, characterized in that said housing (112) is made of plastic.

7. The airbag module according to claim 1, characterized in that a tubular source of compressed gas (40;

140) with a longitudinal axis (L) is attached to said airbag module (10;

110), said connection extension (36;

136) penetrating into said source of compressed gas crosswise to said longitudinal axis (L).

8. The airbag module according to claim 7, characterized in that said connection extension (36;

136) penetrates said source of compressed gas (40;

140) in a middle thereof.

9. The airbag module according to claim 1, characterized in that said housing (12;

112) accommodates an airbag (20;

120) that surrounds said gas lance (22;

122).
