Abstract

A device for triggering an airbag device that is accommodated in a steering wheel is described. The device has a firing cap for an airbag device that is accommodated in a steering wheel and is fired by a light pulse that is supplied via an optical waveguide. A coupling device, which decouples the optical waveguide from the rotation of the steering wheel but ensures that the light pulse is transmitted into the firing cap from the optical waveguide and also ensures that the airbag is inflated by a gas generator, is provided between the optical waveguide and the airbag.
