Abstract: A plurality of spaced pairs of stakes are molded on the back of an airbag module cover. A horn switch assembly which is to be mounted on the back of the airbag module cover has a plurality of spaced pairs of openings along the perimeter thereof which are complementary to and are adapted to receive the spaced pairs of stakes on the cover. Subsequent to the positioning of the pairs of stakes in the complementary pairs of openings, the distal ends of the stake pairs are formed into a unitary bridge by heating. The bridge shaped heat staking thus employed thereby locks the horn switch on the back of the airbag module cover to prevent separation of the switch and cover on the deployment of the airbag and provide a much stronger attachment than standard methods of heat staking.

Abstract: An improved horn switch assembly for use on the steering wheel of a motor vehicle, which horn switch assembly can be activated by pressing on the module cover. The novel horn switch assembly is attached to the bottom of the air bag module. The horn switch assembly comprises a horn switch located between the module housing of the air bag module and a second support bracket for attaching the module to a vehicle steering wheel. This novel horn switch assembly permits servicing or replacement of the horn switches without exposing the internal components of the air bag module.
