Protection of passengers

In Audi A4 two safety cushions in a full-scale size are serially put. The volume of an air bag of a safety cushion of the driver makes about 70 l, and passenger airbags near the driver – about 150 l.

Pyrotechnic mechanisms for a tension of tapes of seat belts in case of collision immediately pull belts sitting ahead. The zone of deformation of a body absorbing energy, and also octagonal cross section of longerons also with high ability of absorption of energy at head-on collision provides the delay substantially transferred by passengers.

The structure of the longerons passing to forward cross support of seats in combination with rigid salon provides steady space of survival.
