Abstract

A detent connection piece (10) includes a clip hook (18) which can be pressed into a first bore (24) while being deformed until the detent connection piece snaps in and engages behind a bearing edge framing the first bore (24). The detent connection piece (10) additionally includes an end section which is adapted to be inserted into a second bore (26). Further proposed is a gas bag module including at least one such detent connection piece (10).

Claims

1. A detent connection piece comprising a clip hook (18) which can be pressed into a first bore (24) while being deformed until said detent connection piece snaps in and engages behind a bearing edge framing said first bore (24), characterized in that said detent connection piece (10) additionally includes an end section which is adapted to be inserted into a second bore (26).

2. The detent connection piece according to claim 1, characterized in that said detent connection piece (10) is formed in one piece from a spring steel sheet.

3. The detent connection piece according to claim 1, characterized in that said detent connection piece (10) has an elastically yielding section (14) adjoining said clip hook (18), for said clip hook (18) to be pressed in more easily.

4. The detent connection piece according to claim 1, characterized in that said detent connection piece (10) has an opening (16) through which said clip hook (18) can be levered out in an assembled state by means of a tool.

5. The detent connection piece according to claim 1, characterized in that said end section forms a guide hook (20) which is adapted to be arrested in said second bore (26).

6. The detent connection piece according to claim 5, characterized in that said detent connection piece (10) has a flat central section (12) and said clip hook (18) and said guide hook (20) extend in a direction perpendicular to a plane of said central section (12).

7. The detent connection piece according to claim 5, characterized in that said guide hook (20) is formed by a bent end section of said detent connection piece (10):

8. The detent connection piece according to claim 1, characterized in that said end section is configured as an attachment section (36) which engages behind a bearing edge framing said second bore (26).

9. The detent connection piece according to claim 8, characterized in that said attachment section (36) is elastically deformable.

10. The detent connection piece according to claim 8, characterized in that said detent connection piece (10) has a flat central section (12) and said attachment section (36) extends in a plane parallel to a plane of said central section (12).

11. The detent connection piece according to claim 8, characterized in that said detent connection piece (10) has a flat central section (12) and said attachment section (36) is turned in relation to said central section (12).

12. A gas bag module, in particular a side gas bag module, comprising a gas bag (30) and a protective sheathing (32) surrounding said gas bag (30), characterized in that said gas bag module (28) comprises at least one detent connection piece (10) including a clip hook (18) which can be pressed into a first bore (24) while being deformed until said detent connection piece snaps in and engages behind a bearing edge framing said first bore (24), said detent connection piece (10) additionally including an end section which is adapted to be inserted into a second bore (26).

13. The gas bag module according to claim 12, characterized in that said detent connection piece (10) is configured in one piece with a housing part of said gas bag module (28).

14. The gas bag module according to claim 12, characterized in that a tongue (34) of said gas bag (30) is pulled over said clip hook (18) of said detent connection piece (10).

15. The gas bag module according to claim 12, characterized in that said detent connection piece (10) is arranged between said gas bag (30) and said protective sheathing (32), with said clip hook (18) and said end section projecting out of said protective sheathing (32).
