Abstract

A side airbag gas bag is provided for a motor vehicle, in particular a passenger car. The gas bag includes, but is not limited to an occupant region and a child seat region adjoining thereon, which with inflated gas bag optionally forms a recess for receiving a contour of a child seat or a volume for the lateral protection of an occupant.

Claims

1. An airbag gas bag for a motor vehicle, comprising:

an occupant region; and

a child seat region adjoining the occupant region, which with the gas bag optionally forms a recess;

wherein the child seat region is defined by a separate and optionally inflatable chamber.

2. The airbag gas bag according to claim 1, further comprising a further child seat region, which with the gas bag optionally forms the recess.

3. The airbag gas bag according to claim 2, wherein the recess is configured to receive a contour of a further child seat.

4. The airbag gas bag according to claim 2, wherein the recess is configured to receive a volume for a lateral protection of an occupant.

5. The airbag gas bag according to claim 1, wherein the child seat region is defined by an optionally releasable limitation device.

6. The airbag gas bag according to claim 1, wherein the occupant region and the child seat region are connected in a materially joined manner.

7. The airbag gas bag according to claim 1, wherein the occupant region and the child seat region with the gas bag inflated form a common contact area when the child seat region forms a volume for a lateral protection of an occupant.

8. The airbag gas bag according to claim 1, wherein the recess is configured to receive a contour of a child seat.

9. The airbag gas bag according to claim 1, wherein the recess is configured to receive a volume for a lateral protection of an occupant.

10. An airbag gas bag arrangement, comprising:

an airbag gas bag that is inflatable, comprising

an occupant region; and

at least one child seat region adjoining the occupant region, which with the gas bag optionally forms a recess; and

an inflating device, comprising

a gas generator configured to inflate the occupant region of the gas bag; and

a further gas generator configured to optionally inflate the at least one child seat region that is defined by at least one separate chamber; and

a control device in communication with the inflating device and configured to control inflation of the at least one separate chamber defining the at least one child seat region.

11. An airbag arrangement, comprising:

an airbag gas bag that is inflatable, comprising

an occupant region; and

a child seat region adjoining the occupant region, which with the gas bag optionally forms a recess;

an inflating device comprising a multi-stage gas generator that is configured to inflate the occupant region and optionally inflate the child seat region defined by a separate chamber; and

a control device in communication with the inflating device and configured to control inflation of the chamber defining the child seat region.

12. An airbag arrangement, comprising:

an airbag gas bag that is inflatable, comprising

an occupant region; and

a child seat region adjoining the occupant region, which with the gas bag optionally forms a recess;

an inflating device; and

a control device in communication with the inflating device and configured to control inflation of the chamber defining the child seat region;

wherein the control device comprises a sensing device that is configured to automatically sense a child seat.

13. An airbag arrangement, comprising:

an airbag gas bag that is inflatable, comprising

an occupant region; and

a child seat region adjoining the occupant region, which with the gas bag optionally forms a recess;

an inflating device; and

a control device in communication with the inflating device and configured to control inflation of the chamber defining the child seat region;

wherein the control device comprises a sensing device that is configured to automatically sense a manually actuatable switching device for selection between a forming of the recess or of a volume of the child seat region.
