a vehicle body comprising an element that essentially extends in a vehicle transverse direction, the vehicle body further comprising a roof frame;
a head airbag that essentially extends in a vehicle longitudinal direction, the head airbag mounted to the roof frame; and
a gas generator adapted to fill the head airbag and fastened on the element of the vehicle body that essentially extends in the vehicle transverse direction, wherein the gas generator is directly fastened in a depression of the element, wherein the depression is in a vertical side of the element, wherein the gas generator comprises a retention device adapted to fasten the gas generator on the element.
2. The motor vehicle according to claim 1 , wherein the element is a windshield crossbeam.
3. The motor vehicle according to claim 1 , wherein the gas generator is removably fastened on the element with the retention device.
4. The motor vehicle according to claim 3 , wherein the retention device includes a hole such that the gas generator is screwed onto the element.
5. The motor vehicle according to claim 1 , wherein the retention device is integrally implemented with the gas generator.
6. The motor vehicle according to claim 1 , wherein the vehicle body further includes an A-column and a window crossbeam, the A-column extending between the roof frame and the window crossbeam, and wherein the gas generator and the head airbag are coupled by a filling tube extending through the A-column.
7. The motor vehicle according to claim 1 , wherein the gas generator is essentially cylindrical and has a longitudinal axis running essentially parallel to a transverse axis of the motor vehicle.
8. The motor vehicle of claim 1 , wherein the vehicle body further comprises a dashboard, the element being within an interior portion of the dashboard.
9. A method for installing a head airbag in a motor vehicle, comprising the steps of:
fastening the head airbag on a roof frame of the motor vehicle;
fastening, in a position forward of a dashboard, a gas generator on an element of a vehicle body that essentially extends in a transverse direction of the motor vehicle, the gas generator being adapted to fill the head airbag, wherein the step of fastening the gas generator on the element comprises the step of directly fastening the gas generator in a depression in a vertical side of the element; and
coupling the gas generator and the head airbag with a filling tube extending through an A-column of the motor vehicle.
10. The method according to claim 9 , wherein the step of fastening the gas generator on the element is executed before completing an interior equipping of the motor vehicle.
11. A motor vehicle, comprising:
a vehicle body comprising an element that essentially extends in a vehicle transverse direction, the vehicle body further comprising a roof frame;
a head airbag that essentially extends in a vehicle longitudinal direction, the head airbag mounted to the roof frame; and
a gas generator adapted to fill the head airbag and fastened on the element of the vehicle body that essentially extends in the vehicle transverse direction, wherein the gas generator is directly fastened in a depression of the element, wherein the depression is in a vertical side of the element,
wherein the vehicle body further comprises a dashboard, the element being forward of the dashboard or within an interior portion of the dashboard.
