Curtain/Head Airbag
On the F01/F02, the curtain airbag for the driver and front passenger side is used as head airbag.
The head airbag extends from the A-pillar to the C-pillar and covers the entire side section at the level of the side windows.
It deploys between the occupants, windows and pillar trim panels.
The system features:
- Extended coverage for front and rear windows.
- Reduction of the risk of glass splinters and objects entering the vehicle.
- Optimized coverage even for different sizes of occupant.
The curtain airbag is housed folded up in the roof frame. It consists of the inflator assembly and the curtain.
In the event of a side impact or of a rollover, the inflator assembly is triggered and a valve to the pressure tank is opened. The stored gas flows through the gas lance into the curtain.
The head airbag is set in the correct position by its mounting on the A-pillar and on the C-pillar. In addition, the curtain deploys between the side windows, pillar trim panels and the occupants.
The structural strength and stability is preserved for several seconds by the closed system.
In connection with the side airbag in the front seat, it provides optimum protection for the occupants in the event of side impact.
The head airbag reduces the movement of the head and other occupant extremities towards the outside during a side impact. This results in lower neck shear forces as well as bending moments in the cervical vertebrae. It additionally prevents direct contact with the side structure or the obstacle thus reducing the risk of head injuries.
