1. A vehicle steering wheel assembly, comprising:
- a molded armature having a first engagement members;
an airbag module including a second engagement members to engage said first engagement members; and
a plurality of switch assemblies engageable with said molded armature and said airbag module, the airbag module is supported by and rests on the switch assemblies, whereby a clearance is formed between said first engagement members and said second engagement members creating a normally separated engagement of said first and second engagement members which contact when an airbag deploys to provide a rigid attachment of the airbag module to the armature.

Abstract
A vehicle steering wheel assembly having a molded armature with outwardly extending spokes for mounting on a steering column. Airbag engagement members extend from an airbag module housing to engage corresponding hub engagement members. The airbag module rests on a multiple of switch assemblies while the engagement members are separated by a clearance. The engagement members are only in contact if the airbag is fired. A clearance between each hub engagement member and each corresponding airbag engagement member assures that there is no interference that may result in undesirable noise or vibration.
