Abstract

An inflatable airbag to protect the occupants of a vehicle from an impact on parts in the vehicle passenger compartment is constructed such that a joining seam of two fabric ends of the airbag is provided in the vicinity of an opening made in the bag fabric. The fabric ends are overlapped to such a degree that together they form the complete edge region around the opening and the opening itself.

Claims

1. An inflatable airbag to protect the occupants of a vehicle from an impact on parts in the vehicle passenger compartment, comprising a bag fabric having at one end thereof a first opening whose complete edge region is reinforced by another end of the bag fabric with a second opening mating with the first opening and joined to the one end of the bag fabric to form only a double layer, and joining seams of the two fabric ends of the airbag provided near sides of the openings, wherein the fabric ends are overlapped in the double layer around the openings such that together they form the complete edge region with the openings so as to define an unobstructed aperture for inflating the airbag.

2. The inflatable airbag according to claim 1, wherein the openings are provided at both fabric ends in an initial cut of the bag fabric.

3. The inflatable airbag according to claim 2, wherein the joining seams of the two fabric ends comprise a first joining seam and an additional fastening seam arranged at opposite sides of the openings.

4. The inflatable airbag according to claim 1, wherein the openings are operatively arranged to receive one of a gas generator receptor and a generator casing.

5. The inflatable airbag according to claim 4, wherein the joining seams of the two fabric ends comprise a first joining seam and an additional fastening seam arranged at opposite sides of the openings.

6. The inflatable airbag according to claim 5, wherein the openings and provided at both fabric ends in an initial cut of the bag fabric.

7. The inflatable airbag according to claim 1, where the joining seams of the two fabric ends comprise a first joining seam and an additional fastening seam arranged at opposite sides of the openings.
