Air bag system
First Claim
1. In a vehicle air bag system having a first switch means therein responsive to a current flow for placing the air bag system in a standby mode upon buckling of a seat belt of an associated seat belt system, the seat belt system including an open circuit when the seat belt is disengaged and a closed circuit upon seat belt buckling, the current flow in the closed circuit delivered to the switch means of the air bag system, the improvement comprising:
- a normally open second switch means in the circuit for delivering current to the air bag system means upon closure;
means connected to said second switch means and positioned within a vehicle seat for response to a user sitting on the seat, said responsive means closing said normally open second switch means connected thereto, said closed second switch means delivering current to said first switch means, whereby to place the air bag system in a ready mode.

Abstract
An improved air bag system comprises a supplemental switch structure incorporated into the user'"'"'s seat for delivering a current to the conventional air bag system irrespective of seat belt engagement. The structure includes an arcuate flexible band coupled to a horizontal band, the latter engaging a spring biased button of a switch. The switch is incorporated into the seat belt circuitry such that a current flows therethrough upon switch closure irrespective of seat belt engagement. The current flow to the air bag system places the air bag system in a ready mode so as to cause air bag inflation upon a sufficient impact of the vehicle bumper with another object.
