Air Bag: Description and Operation

6963 Side airbags

The new 911 Carrera is the first car on the market to use the new generation of the standard Porsche Side Impact Protection System (POSIP). It now comprises two airbags per side: one thorax airbag and one head airbag. A specially adapted thorax airbag is now integrated in both the driver's and passenger's seat to provide optimum protection for the upper body in a side impact. In the event of a crash the airbag, which has a volume of approx. 8 litres, is inflated by a gas generator.

In addition to the thorax airbags, there is also a separate head airbag in each door. With a volume of approx. 8 litres, this airbag offers effective head protection. In the event of a side impact it unfolds from the upper section of the door-trim panel in the shape of a flat cushion. Like the thorax airbag, the head airbag is also inflated using a hybrid generator.

The sensors for detecting a side impact and thus for activating the side airbags are located in the airbag control unit on the centre tunnel and in the area of the side sills.
