Abstract

A steering wheel includes a steering wheel ring, a first spacer in contact with an outer surface of the steering wheel ring at a first location, and a second spacer in contact with the outer surface of the steering wheel ring at a second location. At least one armature is coupled to the steering wheel ring at the first location and the second location, the material of the armature at least partially enveloping the first spacer and the second spacer.

Claims

1. A steering wheel comprising:

a steering wheel ring;

a first spacer in contact with an outer surface of the steering wheel ring at a first location;

a second spacer in contact with the outer surface of the steering wheel ring at a second location;

at least one armature coupled to the steering wheel ring at the first location and the second location, the material of the armature at least partially enveloping the first spacer and the second spacer.

2. The steering wheel of claim 1, wherein the steering wheel ring is a hollow metal tube.

3. The steering wheel of claim 2, wherein the material used to form the armature is selected from the group consisting of aluminum, magnesium, and alloys and combinations thereof.

4. The steering wheel of claim 1, wherein the spacers are provided as clips having terminal ends which do not meet.

5. The steering wheel of claim 4, wherein the spacers are generally “

C”

shaped.

6. The steering wheel of claim 1, wherein the spacers are offset from one another to assist in centering the steering wheel ring in a mold.

7. The steering wheel of claim 1, wherein the spacers have a thickness of between approximately 6 mm and 12 mm.

8. A method for producing a steering wheel, comprising:

providing a plurality of mold inserts in contact with an exterior surface of a steering wheel ring;

providing the steering wheel ring and the mold inserts into a mold cavity; and

introducing a material into the mold cavity to form an armature coupled to the steering wheel ring.

9. The steering wheel of claim 8, wherein the material introduced into the mold cavity is selected from the group consisting of aluminum, magnesium, and alloys and combinations thereof.

10. The steering wheel of claim 9, wherein the mold inserts are made from a material selected from the group consisting of aluminum, magnesium, and alloys and combinations thereof.

11. The steering wheel of claim 8, wherein the steering wheel ring is provided as a hollow metal tube.

12. The steering wheel of claim 8, wherein the steering wheel comprises a steel material.

13. The steering wheel of claim 8, wherein the spacers are offset with respect to each other around the outer surface of the steering wheel ring.

14. The steering wheel of claim 8, wherein the spacers comprise terminal ends that do not touch when provided in contact with the steering wheel ring.

15. A method of producing a steering wheel comprising:

providing a steering wheel ring in a mold cavity;

spacing an outer surface of the steering wheel ring away from walls of the mold cavity with a plurality of spacers coupled to the steering wheel ring; and

molding an armature to the steering wheel ring by providing a metal in the mold cavity.

16. The steering wheel of claim 15, wherein the spacers are provided as clips.

17. The steering wheel of claim 15, wherein the metal provided in the mold cavity comprises magnesium.

18. The steering wheel of claim 15, wherein the spacers are configured to space the steering wheel ring between approximately 6 mm and 12 mm away from the walls of the mold cavity.

19. The steering wheel of claim 15, wherein the spacers are offset from each other to assist in centering the steering wheel ring in the mold cavity.

20. The steering wheel of claim 15, wherein the metal at least partially envelops the spacers.
