Airbag rotary coupler how it works?

An airbag rotary coupler, also known as a clock spring, is a crucial component in vehicles equipped with airbags. It allows for the continuous electrical connection between the airbag system and the vehicle's wiring harness while enabling the steering wheel to rotate freely. The coupler consists of several turns of flat, flexible wire coiled inside a housing, which unwinds and rewinds as the steering wheel turns. This design ensures that the airbag can deploy in the event of a collision without losing electrical connectivity.
