Abstract

A side impact protection device in the form of an inflatable gas bag for an occupant of a motor vehicle includes an outlet opening located on a vertical wall section of a trim part located in front, said opening being closed by a cover when the gas bag is in the resting position. The cover consists of an external frame part fastened to the adjoining trim part and at least two lid halves that are connected integrally with the external frame part. The pivotable lid halves are provided with a decorative covering on the side facing the passenger compartment. The covering has a tear seam located in front of the common connecting area of the lid halves.

Claims

1. A side impact protection device for an occupant of a vehicle, comprising:

an inflatable gas bag;

a vertical wall section of a trim part defining an outlet opening for the gas bag; and

a cover closing said outlet opening with the gas bag in a folded resting position, said cover including an outer frame part mounted on the trim part and at least two pivotable lid halves formed integrally with the outer frame part, said lid halves being provided on a side facing a passenger compartment with a decorative covering, a tear seam being provided in a common connecting area of said lid halves on the covering.

2. A side impact protection device according to claim 1, wherein said lid halves include an upper hinge area and a lower hinge area, and outside of said hinge areas said lid halves are connected by a surrounding weakened line with the outer frame part.

3. A side impact protection device according to claim 1, wherein proximate the tear seam, the two lid halves are spaced with a gap between them, the two lid halves being joined together proximate the tear seam by narrow, upright connecting ribs.

4. A side impact protection device according to claim 1, wherein between the outer frame part and the adjoining lid halves, tear stoppers in the form of upright ribs are provided opposite said common connecting area.

5. A side impact protection device according to claim 1, wherein a separate cover part is provided for each lid half, the separate cover parts being connected together by said tear seam.

6. A side impact protection device according to claim 1, wherein a one-piece covering is provided for the two lid halves, said tear seam being produced by a laser in said common connecting area.

7. A side impact protection device according to claim 1, wherein thin-walled retaining panels are provided internally on the two lid halves, each of said panels being connected with the outer frame part and the adjoining lid half.

8. A side impact protection device according to claim 7, wherein each of said retaining panels is connected by at least one ultrasonic weld with the adjoining lid half.

9. A side impact protection device according to claim 7, wherein each of said retaining panels includes at least one U-shaped loop section guided around the exterior of the outer frame part.

10. A side impact protection device according to claim 9, wherein each of said retaining panels has a mounting flange that is elongate and is connected with a respective one of said lid halves, said mounting flange being connected by a relatively narrow hinge section with an outer retaining section, said U-shaped loop sections being provided on said outer retaining section.

11. A side impact protection device according to claim 7, wherein one of said lid halves defines a mounting opening for receiving a plug, through which opening a mounting screw can be inserted to fasten the retaining panel located behind to a housing of the gas bag.

12. A side impact protection device according to claim 10, wherein the outer frame part of the cover and the outer retaining section of the two retaining panels is secured to the adjoining trim part by ultrasonic welding.

13. A side impact protection device according to claim 10, wherein a plurality of reinforcing ribs running vertically are located on an upper one of said lid halves on both sides of said hinge section of the retaining panel.

14. A side impact protection device according to claim 1, wherein said trim part is formed by door trim.

15. A side impact protection device according to claim 1, wherein said cover is formed by a one-piece injection-molded part made of thermoplastic rubber.
