Abstract
A clock spring and steering wheel rear cover arrangement are particularly well-suited for a modular steering wheel and air bag sub-assembly. The clock spring is attached to the rear of a hub in the steering wheel assembly, and the rear cover snaps behind the clock spring. The clock spring and rear cover may be pre-assembled with the modular steering wheel and air bag such that the entire assembly is attached as a unit to a steering column. A tab from the rear cover may snap into an opening on the rear of the hub. The clock spring may include a hard connection into an air bag igniter, or may utilize a wire harness connection. A single opening in the rear of the hub for the steering column may receive an electrical connection for accessories on the steering wheel along with providing a connection to the air bag igniter. Also, the clock spring housing includes structure to be aligned on the steering column.
Claims
1. A steering wheel assembly comprising:
a steering wheel armature to be gripped by an operator of a vehicle a steering wheel hub fixed to said armature, an air bag assembly received on said hub, and a means to secure said combined armature, hub and air bag to a steering column after pre-assembly of said armature, hub and air bag;
elongate members extending rearwardly from said hub; and
a clock spring having a rotating plate and a fixed housing, said rotating plate having tabs received on said elongate members, and a rear cover sandwiching said clock spring between said rear cover and said hub, said rear cover also having tabs received on said elongate member.
2. An assembly as recited in Claim 1 , wherein said elongate members are bolts which secure a portion of said air bag assembly to said hub, and extend rearwardly through openings in said hub.
3. An assembly as recited in Claim 1 , wherein said rear cover has a tab which snaps into an opening in said hub.
4. An assembly as recited in Claim 1, wherein there is an opening through said rear cover providing access to said means to secure to allow the combination of said armature, said hub, said air bag, said rear cover and said clock spring to all be pre- assembled and then attached to a steering column as a single unit,
5. An assembly as recited in Claim 4. wherein said fixed housing of said clock spring includes structure that allows said unit to move axially along a steering column, while still radially aligning said unit on said steering column.
6. An assembly as recited in Claim 1. wherein said clock spring has a first connection which extends into an opening in said hub to complete communication between a portion of said air bag assembly and said clock spring.
7. An assembly as recited in Claim 6, wherein said electrical connections include a hard connection between said rotating plate of said clock spring, and an opening in an igniter for said air bag assembly .
8. An assembly as recited in Claim 6, wherein said opening in the rear of said hub also receives a second connection to complete electrical connections between components mounted on said steering wheel and said clock spring.
9. An assembly as recited in Claim 8, wherein said cover includes a tab which snaps into an opening in a rear of said hub, and a single opening in said hub receiving said first connection, said second connection and said tab .
10. A steering wheel assembly comprising:
a steering wheel armature to be gripped by an operator of a vehicle, a steering wheel hub fixed to said armature, an air bag assembly received on said hub, and a means to secure said combined armature, hub and air bag to a steering column after pre-assembly of said armature, hub and air bag;
a clock spring having a rotating plate and a fixed housing, a rear cover sandwiching said clock spring between said rear cover and said hub; and
said means to secure said hub allowing the combination of said armature, said hub, said air bag, said rear cover and said clock spring to all be pre-assembled and then attached to a steering column as a single unit.
11. An assembly as recited in Claim 10- wherein said fixed housing o said clock spring includes structure that allows said single unit to move axially along a steering column, while still radially aligning said unit on the steering column.
12. An assembly as recited in Claim 11 , wherein said alignment structure includes pins extending from one of me steering column and said fixed housing into grooves in the other of the steering column and said fixed housing to provide radial alignment of said fixed housing on the steering column.
13. An assembly as recited in Claim 11, wherein said clock spring has a first connection which extends into an opening in said hub to complete communication between a portion of said air bag assembly and said clock spring said first connection includes a hard first connection between said rotating plate of said clock spring, and an opening in an igniter for said air bag assembly.
14. An assembly as recited in Claim 13. wherein said opening in the rear of said hub also receives a second connection to complete electrical connections between components mounted on said steering wheel and said clock spring.
15. An assembly as recited in Claim 14. wherein said cover includes a tab which snaps into an opening in a rear of said hub, and a single opening receiving said first connection, said second connection and said tab.
16. An assembly as recited in Claim 10, wherein said rear cover has a tab which snaps into an opening in said hub to sandwich said hub, said dock spring and said cover.
17. An assembly as recited in Claim 10, wherein said rotating plate has a clip to secure a wire harness on said rotating plate at a desired location.
18. A clock spring comprising:
a rotating housing including electrical connections for connection to a steering wheel sub-assembly, said rotating housing being adapted to rotate with a steering wheel shaft;
a fixed housing to be connected to a steering column housing, the steering column housing surrounding the steering wheel shaft, said fixed housing rotatably supporting a rotating plate; and
structure on said fixed housing for providing radial alignment between said fixed housing and the steering column housing, but allowing relative axial movement between said fixed housing and the steering column housing
19. A clock spring as recited in Claim 18, wherein said structure includes pins formed on one of the steering column housing and said fixed housing, and grooves formed in the other of the steering column housing and said fixed housing.
20. A clock spring as recited in Claim 19, wherein said fixed housing includes said grooves.
21. A clock spring as recited in Claim 18, wherein said electrical connection includes a hard connect to be received in an air bag igniter.
22. A clock spring as recited in Claim 18, wherein said rotating plate includes tabs to be received on elongate members extending from the steering wheel sub-assembly.
