Steering wheel with integrated airbag, comprises electric circuit disabling horn when airbag not correctly joined

摘要

The airbag module is accommodated in the hub area of the steering wheel and hidden underneath an appropriate cover. For joining the module extensions protruding from the bottom of the unit are engaged with recesses provided inside the depression prepared for the insertion of the unit. A first contact button is connected with a cable to the battery of the vehicle and a second contact button with the input of the horn (50). Only when the module is correctly mounted a sound is created by the horn (50) when the center of the steering wheel is pushed.
