Abstract

A steering wheel (102) having a hub portion (118), a rim (112) and at least one spoke (114) connected to the hub portion (118) and to the rim (112), the rim (112) having a groove and a surface of the steering wheel (102); a number of actuatable light sources located in or under the groove; light diffuser or lens (140) positioned in the groove above the light sources.

First claim

The invention claimed is:

1. A steering wheel ( 102 ) having a hub portion ( 118 ), a rim ( 112 ) and at least one spoke ( 114 ) connected to the hub portion ( 118 ) and to the rim ( 112 ), the rim ( 112 ) being hollow and made of a top or first portion ( 122 ) and bottom or second portion ( 124 ) having an annular groove or slot and a top surface of the top or first portion of the steering wheel; a number of actuatable light sources located in or under the annular groove or slot; an annular light diffuser or lens ( 140 ) positioned in the annular groove or slot above the light sources, and the lens ( 140 ) follows the shape of the annular groove or slot, the lens being a translucent or transparent material covered with a thin layer of aluminum or chrome which permits the transmission of light;
at least one vibrator ( 154 ) which when activated creates an informational signal for the driver; and
a controller ( 160 ) to activate the light sources, wherein a pattern or sequence of activating the light sources is chosen to provide an informational signal, which signal includes a warning signal to a driver, wherein illumination of the light source can remain at the top portion of the steering wheel in a driver's field of vision when the steering wheel is being rotated.

2. The steering wheel ( 102 ) according to claim 1 wherein the annular groove or slot substantially extends about the periphery of the top surface.

3. The steering wheel ( 102 ) according to claim 1 wherein each light source is an LED ( 152 ), with a predetermined number of LEDs secured to a circuit board ( 150 ).

4. The steering wheel ( 102 ) according to claim 3 wherein each circuit board ( 150 ) has a mounting surface upon which electrical components can be mounted, the mounting surface having a curved top edge and a curved lower edge.

5. The steering wheel ( 102 ) according to claim 1 wherein each vibrator is connected to a printed circuit board, PCB ( 150 ), which extends across each spoke ( 114 ).

6. The steering wheel ( 102 ) according to claim 1 wherein the vibrators can detect damping of the vibrations in the steering wheel caused by the hands of a driver.

7. The steering wheel ( 102 ) according to claim 1 wherein the vibrators can sense the presence of a driver's hands on the steering wheel.
