Abstract

The invention concerns a multi function steering mechanism having a non-rotatable display panel located within the rim of the steering wheel. Wires of a wiring truss to the display panel are continuous through a hollow non-rotatable support member for the display panel. A rotatably steering link is off set from the support shaft and geared to a cylindrical gear hub of the steering wheel which is rotatably supported on either the support column or onto an outer housing for the mechanism. The support member, steering link and wheel, with or without the actual display panel, may be provided as a replacement unit for a conventionally mounted steering wheel.

Claims

1. A multi function steering mechanism for a motor vehicle, including a display console, comprising:

a non-rotatable, hollow support member carrying a rotatable steering wheel at one end and disengagably attachable with a steering shaft of the motor vehicle at the other end;

the steering wheel being engagable with the steering shaft via an elongate link journalled in the hollow support member end located to be offset from the steering shaft when it is attached to the steering shaft, the link being operatively connected at one end to the steering wheel and being operatively engagable at another end to the steering shaft whereby the axis of rotation of the steering wheel is aligned with the steering shaft and rotation of the steering wheel acts to rotate the link and, hence, when connected, the steering shaft;

a display panel non-rotatably connected to the support member having a front display face located within the periphery of the steering wheel;

a wiring truss within the support member, individual wires of which wiring truss are directly connected to individual units of the display panel.

2. A multi function steering mechanism as claimed in claim 1 in which the offset link is rotatably supported on the support member.

3. A multi function steering mechanism as claimed in claim 2, in which the steering wheel is journalled for rotation on the support member.

4. A multi function steering mechanism as claimed in claim 3, in which the rotatable steering wheel includes a cylindrical hub, an inner surface of which is journalled on the support member for rotation.

5. A multi function steering mechanism as claimed in claim 4, in which the offset link comprises a tool having first gear means at one end meshing with the steering wheel gear means and second gear means at the other end meshing with steering shaft gear means.

6. A multi function steering wheel as claim ed in claim 5, in which the first gear means meshes with steering wheel gear means on the cylindrical hub.

7. A multi function steering mechanism as claimed in claim 1, in which the display panel includes a recessed display screen.

8. A multi function steering mechanism as claimed in claim 1, in which the display panel includes a recess in which an inflatable air bag is housed.

9. A multi function steering mechanism as claimed in claim 1, in which the display panel includes a speaker telephone hingably movable between an "on-hook" position and an "off-hook" position.
