Abstract

A method for installing an airbag assembly within a steering wheel assembly includes locating an airbag module engagement member with a corresponding armature engagement member. Once aligned, an operator presses downward on the airbag cover until switch engagement members engage their corresponding switch assembly receivers within the airbag cover. A clearance is formed between each armature engagement members and the corresponding airbag module engagement members when the module is mounted to the molded armature. Thus the switch assemblies support the airbag module.

Claims

1. A method of mounting an airbag module to a molded armature, comprising the steps of:

(1) providing an armature engagement member extending from a steering wheel hub;

(2) engaging a multiple of switch assemblies with the steering wheel hub;

(3) aligning an engagement member extending from an airbag module with the armature engagement member; and

(4) engaging the multiple of switch assemblies with the airbag module such that a clearance is formed between the armature engagement member and the airbag module engagement member and the airbag module is supported by the switch assemblies.

2. A method as recited in claim 1, wherein step 1 includes providing the armature engagement member at a 6 o'"'"'clock position along the molded armature.

3. A method as recited in claim 1, wherein step 3 includes tilting the airbag module relative to the molded armature.

4. A method as recited in claim 1, wherein step 4 includes snapping the multiple of switch assemblies to the airbag module.

5. A method as recited in claim 1, wherein step 4 includes engaging the multiple of switch assemblies to an airbag cover attached to the airbag module.

6. A method as recited in claim 1, further including biasing the airbag module relative the molded armature.

7. A method as recited in claim 1, wherein step 2 includes engaging one of the multiple of switch assemblies proximate a spoke of the molded armature.

8. A method of mounting an airbag module to a molded armature, comprising the steps of:

(1) providing a plurality of armature engagement members extending from a steering wheel hub, one of the plurality of armature engagement members located at a 6 o'"'"'clock position relative to the molded armature;

(2) engaging a plurality of switch assemblies with the steering wheel hub;

(3) tilting the airbag module relative to the molded armature;

(4) aligning an airbag module engagement member extending from an airbag module with the armature engagement member located at a 6 o'"'"'clock position; and

(5) engaging the plurality of switch assemblies with an airbag cover of the airbag module such that a clearance is formed between the plurality of armature engagement members and a corresponding plurality of airbag module engagement members and the airbag module is supported by the switch assemblies.

9. A method as recited in claim 8, further including biasing the airbag module relative the molded armature.

10. A method as recited in claim 8, further including connecting the plurality of switch assemblies to a vehicle horn circuit.

11. A method as recited in claim 8, wherein step 2 includes engaging one of the multiple of switch assemblies proximate a spoke of the molded armature.
