Abstract

It is provided a vehicle seat for a motor vehicle, comprising a gas bag inflatable for the protection of a vehicle occupant, which in the inflated condition extends on a side of the vehicle seat facing a vehicle interior; and a retaining element via which the gas bag is connected with a backrest frame of the vehicle seat. There is further provided at least one fastening structure molded to the retaining element, via which a positive connection of the retaining element with the backrest frame exists.

Claims

1. A vehicle seat for a motor vehicle, comprising

a gas bag inflatable for the protection of a vehicle occupant, which in the inflated condition extends on a side of the vehicle seat facing a vehicle interior,

a retaining element via which the gas bag is connected with a backrest frame of the vehicle seat, and

at least one fastening structure molded to the retaining element, via which a positive connection of the retaining element with the backrest frame exists.

2. The vehicle seat according to claim 1, wherein the fastening structure is integrally molded to the retaining element.

3. The vehicle seat according to claim 1, wherein the fastening structure encloses or extends through a portion of the backrest frame.

4. The vehicle seat according to claim 3, wherein the fastening structure comprises several protrusions spaced apart from each other, which each enclose the portion of the backrest frame.

5. The vehicle seat according to claim 1, wherein via the fastening structure the retaining element is connected with a front region of the backrest frame as seen in the direction of forward travel.

6. The vehicle seat according to claim 1, wherein the fastening structure at least partly encloses a front portion of the backrest frame, which has a side pointing in the direction of forward travel.

7. The vehicle seat according to claim 1, wherein the fastening structure extends through an opening formed in the front region of the backrest frame.

8. The vehicle seat according to claim 1, wherein via the fastening structure a latching connection exists between the retaining element and the backrest frame.

9. The vehicle seat according to claim 1, wherein the retaining element extends in a vertical direction along a lateral frame part of the backrest frame.

10. The vehicle seat according to claim 1, wherein the gas bag is connected with the retaining element via at least one connecting element.

11. The vehicle seat according to claim 10, wherein the connecting element, based on the inflated condition of the gas bag, extends along a vertical extension of the gas bag.

12. The vehicle seat according to claim 11, wherein the connecting element includes at least one fastening opening via which it is positively connected with the retaining element.

13. The vehicle seat according to claim 12, wherein the connection consists in that the fastening structure molded to the retaining element extends through the fastening opening.

14. The vehicle seat according to claim 10, wherein the connecting element is a fabric element.

15. The vehicle seat according to claim 1, further comprising a housing in which the gas bag is arranged, wherein the retaining element and the fastening structure is formed by a portion of the housing.

16. A vehicle seat for a motor vehicle, comprising

a gas bag inflatable for the protection of a vehicle occupant, which in the inflated condition extends on a side of the vehicle seat facing a vehicle interior;

a retaining element via which the gas bag is connected with a backrest frame of the vehicle seat, wherein the retaining element is formed by a gas generator support arranged on an outer side of the backrest frame;

at least one connecting element via which the gas bag is connected with the retaining element,

wherein the connecting element with one portion extends on an inner side of at least one portion of the backrest frame.

17. The vehicle seat according to claim 16, wherein the retaining element is formed by a gas generator support via which a gas generator for inflating the gas bag also is fixed to the backrest frame.

18. The vehicle seat according to claim 16, wherein the connecting element extends over the entire inner side of the backrest frame.

19. The vehicle seat according to claim 16, wherein the retaining element is arranged on the inner side of the backrest frame.

20. A vehicle seat for a motor vehicle, comprising:

a gas bag inflatable for the protection of a vehicle occupant, which in the inflated condition extends on a side of the vehicle seat facing a vehicle interior;

a retaining element via which the gas bag is connected with a backrest frame of the vehicle seat, wherein the retaining element is arranged on the inner side of the backrest frame;

at least one connecting element via which the gas bag is connected with the retaining element,

wherein the connecting element with one portion extends on an inner side of at least one portion of the backrest frame; and

,

wherein on an outer side of the backrest frame a gas generator support is arranged, wherein the retaining element is connected with the gas generator support via at least one fastening element which extends through an opening in the backrest frame.
