Motor vehicle and method for operating a motor vehicle
View Patent ↗A motor vehicle having a vehicle cabin, in which at least one front seat and at least one rear seat are arranged, and having a side impact protection system including an airbag apparatus associated with the front seat and an airbag apparatus associated with the rear seat. In order to functionally improve the motor vehicle, the airbag apparatuses include a respective chest airbag and a head airbag, wherein the chest airbag and the head airbag are inflatable by a common gas generator via a manifold.
1. A motor vehicle comprising:
a vehicle cabin,
at least one front seat and at least one rear seat arranged in the cabin, and
a side impact protection system comprising a front airbag apparatus associated with the front seat and a rear airbag apparatus associated with the rear seat,
wherein each airbag apparatus comprises a chest airbag and a head airbag that is separate from the chest airbag, wherein the chest airbag and the head airbag are inflatable by a common gas generator via a manifold,
wherein the head airbag of the rear airbag apparatus includes an additional head protection portion to protect an occupant positioned in a supine position on the front seat, said additional head protection portion extending downward in a vertical direction beside the chest airbag of the rear airbag apparatus, and said additional head protection portion extending in a horizontal direction and located between the chest airbag of the rear airbag apparatus and the chest airbag of the front airbag apparatus.
2. The motor vehicle according to claim 1 , wherein a range of effect of the head airbag associated with the rear seat reaches in a longitudinal vehicle direction up to a range of effect of the head airbag associated with the front seat.
3. The motor vehicle according to claim 1 , wherein the chest airbag of the front seat and/or the rear seat comprise(s) an elastic and gas-tight membrane belt that is adhered along a longitudinal circumference of the chest airbag.
4. The motor vehicle according to claim 3 , wherein the membrane belt extends along an exposed curve on the chest airbag.
5. The motor vehicle according to claim 1 , wherein the side impact protection system is disposed within doors of the motor vehicle.
6. In a motor vehicle including a vehicle cabin, at least one front seat and at least one rear seat arranged in the cabin, and a side impact protection system comprising a front airbag apparatus associated with the front seat and a rear airbag apparatus associated with the rear seat, wherein each airbag apparatus comprises a chest airbag and a head airbag that is separate from the chest airbag, wherein the head airbag of the rear airbag apparatus includes an additional head protection portion to protect an occupant positioned in a supine position on the front seat, said additional head protection portion extending downward in a vertical direction beside the chest airbag of the rear airbag apparatus, and said additional head protection portion extending in a horizontal direction and located between the chest airbag of the rear airbag apparatus and the chest airbag of the front airbag apparatus, a method for operating the motor vehicle comprises:
inflating the chest airbag and the head airbag by a common gas generator via a manifold.
7. A side impact protection system for a vehicle, said side impact protection system comprising:
a front airbag apparatus associated with a front seat of the vehicle, and
a rear airbag apparatus associated with a rear seat of the vehicle,
wherein each airbag apparatus comprises a chest airbag, a head airbag that is separate from the chest airbag, a manifold connecting the chest airbag and the head airbag, an elastic and gas-tight membrane belt that is fixed along a longitudinal circumference of the chest airbag, and a gas generator for inflating the chest airbag and the head airbag via the manifold,
wherein the head airbag of the rear airbag apparatus includes an additional head protection portion to protect an occupant positioned in a supine position on the front seat, said additional head protection portion extending downward in a vertical direction beside the chest airbag of the rear airbag apparatus, and said additional head protection portion extending in a horizontal direction and located between the chest airbag of the rear airbag apparatus and the chest airbag of the front airbag apparatus.
8. The side impact protection system according to claim 7 , wherein the side impact protection system is disposed within doors of the motor vehicle.
