Airbag arrangement
View Patent ↗A housing for an airbag arrangement of a vehicle occupant protection device including at least two housing parts, each part including a side wall terminating in at least one connecting edge. The housing parts by way of the connecting edges lying contiguous with one another when the housing is closed. The housing also includes further comprises a passage opening for an electrical connection lead to be connected to a component of the airbag arrangement, said opening being formed in the side wall of one of the housing parts at an interval from the or each connecting edge. The housing includes an access opening, formed in the side wall of a housing part and running from the connecting edge to the passage opening, through which an electrical connection lead aligned at an angle to the side wall.
1. A housing for an airbag arrangement of a vehicle occupant protection device, comprising
at least two housing parts, each housing part including a side wall terminating in at least one connecting edge, the housing parts by way of the connecting edges lying contiguous with one another when the housing is closed;
a passage opening for an electrical connection lead to be connected to a component of the airbag arrangement, the opening being formed in the side wall of one of the housing parts at an interval from the at least one connecting edge; and
an access opening, formed in the side wall of the one of the housing parts and running from the connecting edge to the passage opening, wherein the electrical connection lead is aligned at an angle to the side wall and can be introduced into the passage opening via the access opening.
2. The housing as claimed in claim 1 , wherein the housing parts are connected together at the connecting edges.
3. The housing as claimed in claim 1 , wherein only one of the housing parts includes a passage opening.
4. The housing as claimed in claim 1 , wherein the passage opening is approximately of fully circular design shape.
5. The housing as claimed in claim 1 , wherein the access opening is a slot.
6. The housing as claimed in claim 1 , wherein the access opening runs in an approximately straight line.
7. The housing as claimed in claim 1 , wherein the access opening counteracts an electrical connection lead, introduced into the passage opening, being drawn out of the housing part through the access opening to the connecting edge.
8. The housing as claimed in claim 1 , wherein the access opening follows a curved course, at least in sections.
9. The housing as claimed in claim 1 , wherein the access opening follows a meandering course, at least in sections.
10. The housing as claimed in claim 1 , wherein the access opening follows an indented course, at least in sections.
11. The housing as claimed in claim 1 , wherein the side wall has a stabilizing structure in the area of the access opening and/or in the area of the passage opening.
12. The housing as claimed in claim 11 , wherein the stabilizing structure is formed by a thickening of the side wall.
13. The housing as claimed in claim 11 , wherein the stabilizing structure has a web or a bead arranged on the side wall.
14. An airbag module for a vehicle occupant restraint system, comprising
a housing as claimed in claim 1 ;
a component arranged in the housing;
an electrical connection lead, which extends through the passage opening in the housing to the component.
15. The airbag module as claimed in claim 14 , wherein the housing parts of the housing lie with their connecting edges on top of each other, so as to prevent the electrical connection lead being drawn out of the one housing part through the access opening formed therein to the connecting edge.
16. The airbag module as claimed in claim 14 , wherein an inflatable airbag is arranged in the housing and the component is a gas generator for inflation of the airbag.
17. The airbag module as claimed in claim 16 , wherein the electrical connection lead is an ignition cable, via which the gas generator can be connected to electronics arranged outside the housing for triggering the gas generator.
18. The airbag module as claimed in claim 14 , wherein the access opening is of slot-like design and has a width, measured transversely to the main direction in which it extends, which is smaller than the outside diameter of the electrical connection lead or which is equal to the outside diameter of the electrical connection lead.
19. The airbag module as claimed in claim 14 , wherein the access opening is of slot-like design and has a width, measured transversely to the main direction in which extends, which is greater than the outside diameter of the electrical connection lead.
20. The airbag module as claimed in claim 14 , wherein a continuous retaining element, which prevents the electrical connection lead being drawn out of the housing part through the access opening to the connecting edge, extends over the access opening.
21. The airbag module as claimed in claim 14 , wherein a cable drag relief structure interacts with the electrical connection lead, which prevents the electrical connection lead being drawn out of the housing in a direction parallel to the direction in which the electrical connection lead extends.
22. The airbag module as claimed in claim 21 , wherein the cable drag relief structure comprises an element arranged on the electrical connection lead and bearing on the edge of the passage opening.
23. The airbag module as claimed in claim 21 , wherein the cable drag relief structure comprises a radial indentation in the electrical connection lead, in which the edge of the passage opening engages.
24. The airbag module as claimed in claim 21 , wherein the side wall in the area of the passage opening has a stabilizing structure, which counteracts any bending of the side wall under a force exerted on the side wall by the cable drag relief structure.
