Abstract

A passive restraining system for an automobile provides a means, in the event of an automobile accident, for inflating an air bag system on the driver's side at a lower threshold speed if the driver is not wearing a seat belt, and at a higher threshold speed if the driver is wearing a seat belt. This system, however, allows a second air bag system to inflate for protecting the front seat passenger in the event of an accident, at the lower threshold speed, regardless of whether the passenger is wearing a seat belt or not.
