Abstract

A safety device for a motor vehicle and a method for producing such a safety device are provided. The safety device comprises an expansion body with an elastic diaphragm that delimits a hollow space. A filling fluid source is configured for filling the hollow space subject to elastic expansion of the diaphragm.

Claims

1. A safety device for a motor vehicle, the safety device comprising:

an expansion body with an elastic diaphragm that delimits a hollow space; and

a filling fluid source is configured for filling the hollow space subject to elastic expansion of the elastic diaphragm.

2. The safety device according to claim 1, wherein the expansion body comprises two hollow spaces that are in a design filling state and that have different or same volumes, outer contours and/or filling pressures.

3. The safety device according to claim 1, wherein the expansion body comprises two hollow spaces and the safety device further comprises a control device configured for setting different filling and/or emptying behaviors of the two hollow spaces.

4. The safety device according to claim 1, further comprising a variable, fluid passage between two hollow spaces.

5. The safety device according to claim 1, wherein the elastic diaphragm is connected through a materially joined connection to a further elastic diaphragm, which delimits a further hollow space.

6. The safety device according to claim 1, wherein the hollow space at least partially encloses a recess that is open on one or both sides.

7. The safety device according to claim 1, wherein the hollow space is closed off by a covering.

8. The safety device according to claim 1, wherein the hollow space is partially delimited by a material that opens out upon filling.

9. The safety device according to claim 1, further comprising a carrier that delimits the hollow space and to which the elastic diaphragm is fastened.

10. The safety device according to claim 9, wherein the elastic diaphragm is releasably fastened to the carrier through forming or casting of the carrier and/or of the elastic diaphragm.

11. The safety device according to claim 9, wherein the elastic diaphragm is materially connected to the carrier through vulcanizing.

12. The safety device according to claim 9, wherein the carrier is a generator flange, an expansion body housing, an expansion body covering, a vehicle structure element, vehicle interior covering element, vehicle seat element, or a part thereof.

13. The safety device according to claim 1, wherein the expansion body comprises an envelope that at least partially encloses the elastic diaphragm.

14. A method for producing a safety device comprising:

an expansion body with an elastic diaphragm that delimits a hollow space and comprising a further hollow space; and

a filling fluid source is configured for filling the hollow space subject to elastic expansion of the elastic diaphragm, the method comprising;

connecting the elastic diaphragm to a further elastic diaphragm, which delimits the further hollow space, through a materially joined connection or integrally with each other.
