SHOCK ABSORBING MECHANISM
.
PRIMARY IMPACT
When the vehicle is in a collision and there is a force applied to
the steering column assembly from the steering gear, the col-
lapse device is contracted to absorb the shock load. This pre-
vents the steering column from moving into the passenger
compartment during the impact.
.
SECONDARY IMPACT
1. When the driver's body falls against the deployed air bag,
the tilt bracket (A) moves forward by crushing the polyacetal
resin, causing the steering column assembly to move
towards the engine compartment.
