Passive Safety Systems And Airbags: Notes

Passive Safety  is a concept that deals with the protection of the vehicles occupants once a collision is unavoidable, this is in contrast to Active Safety  which assists the driver to avoid a crash (i.e. suspension, ABS/DSC, etc).

The corner stone of passive safety is the vehicle passenger cell or "safety cage". The use of pre-determined crumple zones coupled with the door anchoring system allows the passenger cell to retain a stable shape when the vehicle is involved in an accident.

The use of passenger restraint systems (safety-belts with tensioners) and airbags help to enhance passenger safety by providing the occupants with additional protection during a collision.
