## Abstract

A motor vehicle airbag has a support structure that is moveable from a storage position into a support position, and at least one cover element by means of which a support volume of the airbag formed by the support structure in its support position is surrounded at least in regions. At least one separating element, which at least partially divides the support volume into at least two chambers, is arranged in the support volume. The separating element has at least one through-flow opening via which gas received in one of the chambers in the support position can be at least partially guided into the other chamber.

## Claims

### Claim at position 1

1-7. (canceled)

### Claim 8

A motor vehicle airbag, comprising:
a support structure moveable from a storage position into a support position;
at least one cover by means of which a support volume of the airbag formed by the support structure in its support position is surrounded at least in regions;
at least one separator, which at least partially divides the support volume into at least two chambers, is arranged in the support volume, wherein the at least one separator has at least one through-flow opening via which a gas received in one of the at least two chambers in the support position is able to at least partially be transferred into the other of the at least two chambers.

### Claim 9 (depends on 8)

The airbag of claim 8, wherein in the support position, one of the at least two chambers is arranged to catch a thorax region of a passenger of the motor vehicle and the other of the least two chambers is arranged to catch a head of the passenger.

### Claim 10 (depends on 8)

The airbag of claim 8, wherein in the support position, one of the at least two chambers has a greater level of hardness than the other of the at least two chambers.

### Claim 11 (depends on 8)

The airbag of claim 8, further comprising:
at least valve element arranged in the through-flow opening, wherein the valve is adjustable between a closed position sealing the through-flow opening and at least one open position that at least partially releases the through-flow opening.

### Claim 12 (depends on 8)

The airbag of claim 8, wherein the separator is formed from textile.

### Claim 13 (depends on 12)

The airbag of claim 12, wherein the textile is fabric.

### Claim 14 (depends on 8)

The airbag of claim 8, wherein the separator is non-rigid.

### Claim 15 (depends on 8)

The airbag of claim 8, further comprising:
at least one actuator, which is arranged to supply a gaseous medium into the support structure to move the support structure into the support position; and
at least one channel flowing into one of the at least two chambers to guide the gaseous medium from the actuator into the one of the at least two chambers.
