In the event of a crash, the knee airbag supports the knee, especially if the driver or passenger are not wearing seatbelts. This initiates a controlled forward shift of the upper body, which is cushioned by the relevant airbag.

The knee airbag is a one-stage airbag with gas generator. The volume is approx. 13 litres.
