AIR BAG SYSTEM

Operation

Before Activation (Normal Condition)

• The spool has a pinion on its end, which rotates with the spool when the belt webbing is retracted or withdrawn.

• There is a ring gear around the pinion. Because the pinion does not engage with the ring gear during normal

operation, the ring gear does not rotate even when the belt webbing is retracted or withdrawn.

During Activation

1. When the pre-tensioner seat belt system receives an operation signal from the SAS control module, gas is

produced from each generator forcing up the balls in the tube.

2. The balls shift, pushing the ring gear toward the pinion. Due to this, the ring gear and pinion are engaged.

3. The ball shifting makes the ring gear rotate. The pinion, coupled with the rotation of the ring gear, rotates the

spool in the direction of retraction. Thus the belt webbing is tightened.
