Abstract
A steering wheel is provided and may include an armature having a rim and a coating at least partially surrounding the rim. A pair of electrodes may be respectively disposed within a pair of grooves formed in the coating. A polymer paint may be disposed on the coating and may include a plurality of carbon filaments that receive voltage from at least one of the pair of electrodes to selectively generate heat.
Claims18
A steering wheel comprising:
- an armature including a rim;
- a coating at least partially surrounding said rim;
- a pair of electrodes respectively disposed within a pair of grooves formed in said coating, said electrodes being flush with an outer surface of said coating when disposed within said pair of grooves;
- and
- a polymer paint disposed on said coating and including a plurality of carbon filaments that are in electrical communication with said electrodes and are operable to receive voltage from at least one of said pair of electrodes to selectively generate heat.

A heating system for a steering wheel having a rim, the heating system comprising:
- a coating surrounding the rim;
- a first electrode attached to the rim via said coating, said first electrode being flush with an outer surface of said coating;
- a second electrode attached to the rim via said coating, said second electrode being flush with said outer surface of said coating;
- a polymer paint applied to said coating and in electrical communication with said first electrode and said second electrode, said polymer paint including a plurality of carbon filaments operable to receive voltage from at least one of said first electrode and said second electrode to selectively generate heat;
- and
- a wrap disposed over said polymer paint and operable to receive said heat from said carbon filaments.
