Abstract
A vehicle steering wheel assembly having a molded armature with outwardly extending spokes for mounting on a steering column. Airbag module engagement members extend from an airbag module housing to engage corresponding armature 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 armature engagement member and each corresponding airbag module engagement member assures that there is no interference that may result in undesirable noise or vibration.
