SRS Airbag Construction and Operation – Spiral cable


A spiral cable is used as an electrical joint from the vehicle body side to the steering wheel.
The spiral cable is made up of the rotator, case, cable, cancel cam, etc.
The case is installed in the combination switch assembly. The rotator turns together with the steering wheel.
The cable is 4.8 m* long and is stored inside the case so that there is some slack in it.
One end of the cable is fixed to the case, while the other end is fixed to the rotator.
When the steering wheel is turned to the right or the left, it can be turned by the amount of slack in the cable (2-1/2 turns*).
*Varies according to the vehicle model
