A dual stage air bag suppression system based upon seat position. A deceleration sensor senses the deceleration of the vehicle during a crash/collision. If the deceleration exceeds a first threshold value, and the seat is rearward of a predetermined value, then the SIR Controller initiates a first/low stage inflation. If the deceleration exceeds a second higher threshold value, and the seat is rearward of a predetermined value, then the SIR Controller initiates both first/low and second/high stages of inflation. If the seat is positioned at a point forward of a predetermined position, then the SIR Controller initiates the first/low stage inflation only when the deceleration exceeds the first/lower or second/higher threshold value and suppresses deployment of the second stage. Thus the SIR Controller initiates the inflation stages not only based on the severity of the collision or deceleration, but also based on the position of the vehicle seat.

[ What is claimed is:] [11.]11. An air bag suppression system in a vehicle comprising:a supplemental inflatable restraint system including an air bag deployable in a first low inflation stage and a second high inflation stage;a seat position detecting means for detecting a position of a seat within said vehicle;a sensing means for sensing a severity of a collision event of said vehicle; anda controller for selectively initiating said first low and said second high inflation stages of said air bag dependent on said seat position detecting means and said sensing means, wherein when said seat position detecting means detects said position of said seat rearward of a predetermined position said controller initiates said first low inflation stage only when said sensing means senses a severity not less than a first threshold value and initiates said second high inflation stage only when said sensing means senses a severity not less than a second threshold value, and when said seat position detecting means detects said position of said seat forward of said predetermined position said controller initiates said first low inflation stage only when said sensing means senses a severity not less than said second threshold value and prohibits initiation of said second high inflation stage.
