Abstract

A vehicle seat arrangement for a motor vehicle is provided. The vehicle seat arrangement comprising a vehicle seat, which comprises at least one inflatable element for protecting a vehicle occupant residing on the vehicle seat. The inflatable element is formed and arranged such that said element expands predominantly in direction towards the vehicle occupant when inflated. The inflatable element is integrated into a backrest of the vehicle seat unfolded or provided with only one fold or a protuberance, wherein the inflatable element is arranged between a cushion of the vehicle seat and a cover of the vehicle seat or inside the cushion.

Claims

1. A vehicle seat arrangement for a motor vehicle comprising

a vehicle seat which comprises at least one inflatable element for protecting a vehicle occupant residing on the vehicle seat, wherein

the inflatable element is formed and arranged such that said element expands predominantly in direction towards the vehicle occupant when inflated, wherein

the inflatable element is integrated in a backrest of the vehicle seat unfolded or provided only with one fold, wherein

the inflatable element is arranged between a cushion of the vehicle seat and a cover of the vehicle seat or inside the cushion;

wherein said inflatable element includes a first section of the inflatable element arranged at an internal side of a backrest frame section and a second section of the inflatable element arranged at an external side of the backrest frame section.

2. The vehicle seat arrangement according to claim 1, wherein the inflatable element extends in the inflated status largely between a side of the vehicle seat built into the vehicle, wherein said side faces a vehicle longitudinal side being closer to the vehicle seat, and the vehicle occupant.

3. The vehicle seat arrangement according to claim 1, wherein the inflatable element is formed and arranged such that while expanding said element exerts a force onto the vehicle occupant which moves the occupant away from a vehicle side of the vehicle.

4. The vehicle seat arrangement according to claim 3, wherein the inflatable element is formed for exerting the force onto the vehicle occupant before said inflatable element comes in contact with a section of a vehicle side structure intruding into the vehicle interior space.

5. The vehicle seat arrangement according to claim 1, wherein the inflatable element is arranged at or in a section of a side cheek of the vehicle seat, wherein said section faces the vehicle occupant.

6. The vehicle seat arrangement according to claim 1, wherein the inflatable element rests against the cushion and/or the cover.

7. The vehicle seat arrangement according to claim 1, further comprising fixing means via which the inflatable element is fixed to a structure of the vehicle seat such that the direction of expanding the inflatable element is influenced.

8. The vehicle seat arrangement according to claim 1 wherein the inflatable element is integrated in a backrest of the vehicle seat unfolded and the inflatable element extends flat in the unfolded status.

9. A method for protecting a vehicle occupant comprising the steps of:

providing a vehicle seat comprising an inflatable element, said element is integrated in a backrest of a vehicle seat unfolded or only provided with one fold,

wherein said inflatable element includes a first section of the inflatable element arranged at an internal side of a backrest frame section and a second section of the inflatable element arranged at an external side of the backrest frame section;

inflating the inflatable element such that it expands predominantly in direction towards the vehicle occupant, wherein

the inflatable element is arranged between a cushion of the vehicle seat and a cover of the vehicle seat or inside the cushion.

10. A vehicle seat arrangement for a motor vehicle comprising

a vehicle seat which comprises at least one inflatable element for protecting a vehicle occupant residing on the vehicle seat, wherein

the inflatable element is formed and arranged such that said element expands predominantly in direction towards the vehicle occupant when inflated, wherein

the inflatable element is integrated in a backrest of the vehicle seat unfolded or provided only with a one fold, wherein

the inflatable element is arranged between a cushion of the vehicle seat and a cover of the vehicle seat;

wherein said inflatable element includes a first section of the inflatable element arranged at an internal side of a backrest frame section and a second section of the inflatable element arranged at an external side of the backrest frame section.
