Motor vehicle with a body structure and with a side impact protection device
View Patent ↗A motor vehicle includes a body structure that has a lateral structure, a vehicle seat that is mounted on the body structure, and a side impact protection device for a passenger in the vehicle. The side impact protection device includes a head airbag with a first inflation device that can deploy upward in the region of the breastwork of the lateral structure, and a side airbag with a second inflation device that can deploy laterally out of the seat. In order for the side impact protection device to be used for different body structures, the side airbag is designed as a thorax airbag, which, in its ready state, is positioned, together with the second inflation device, inside the seat back of the vehicle seat, and can deploy essentially toward the front out of the side wall of the seat back. When the thorax airbag is in its deployed state, its upper edge comes to rest next to the breastwork of the lateral structure.

a side impact protection device for a passenger in the vehicle, the side impact protection device including a head airbag, with a first inflation device that can deploy upward in a region of a breastwork of the lateral structure, and a side airbag, with a second inflation device that can deploy laterally from the seat,
wherein the side airbag is designed as a thorax airbag which, in a ready position, is arranged, together with the second inflation device, inside a seat back of the vehicle seat, and which can deploy out of a side wall of the seat back essentially toward a front,
wherein, when the thorax airbag is in its deployed state, its upper edge comes to rest next to the breastwork of the lateral structure, and
wherein the head airbag deploys from the breastwork only upward and parallel to a side window.
5. A motor vehicle comprising:
a body structure that has a lateral structure,
a vehicle seat that is fastened to the body structure, and
a side impact protection device for a passenger in the vehicle, the side impact protection device including a head airbag, with a first inflation device that can deploy upward in a region of a breastwork of the lateral structure, and a side airbag, with a second inflation device that can deploy laterally from the seat,
wherein the side airbag is designed as a thorax airbag which, in a ready position, is arranged, together with the second inflation device, inside a seat back of the vehicle seat, and which can deploy out of a side wall of the seat back essentially toward a front,
wherein, when the thorax airbag is in its deployed state, its upper edge comes to rest next to the breastwork of the lateral structure,
wherein a deployment opening for the thorax airbag lies below a level of the breastwork on the side wall of the seat back, on a thorax protection module, or both below the level of the breastwork on the side wall of the seat back and on the thorax protection module, and
wherein the head airbag with the first inflation device is positioned directly below the breastwork.
6. A motor vehicle comprising:
a body structure that has a lateral structure,
