Abstract

A steering wheel arrangement is disclosed which incorporates a fixed element (20). The fixed element carries a first annular bearing (33) which supports a steering wheel for rotation relative to the fixed element (20). The fixed element also carries a second bearing (38) which rotatably supports a component to be connected to part of the steering column of a motor vehicle. Each of the bearings are retained, to the fixed element (20), by means of a first resilient retaining element (40), and the first bearing (33) is also retained to the steering wheel by a second resilient retaining element (41).

Claims

1. A steering wheel arrangement, the steering wheel arrangement comprising a fixed element, the fixed element carrying a first annular bearing, the annular bearing supporting a steering wheel for rotation relative to the fixed element, the fixed element also carrying a second bearing, the second bearing rotatably supporting a component to be connected to part of the steering column of a vehicle, the bearings both being retained to the fixed element by a first resilient retaining element, the first bearing being retained to the steering wheel by a second resilient retaining element.

2. An arrangement according to claim 1 wherein the fixed element has a housing part with an upper surface, the upper surface having at least two levels, the outer periphery of the upper surface defining a wall, the first bearing being mounted to that wall, the upper surface defining an opening having a side wall, the second bearing being mounted to that side wall;

wherein the first retaining element comprises a plate which lies over the upper surface, the plate having a part which is resiliently biased into contact with part of the first bearing and with part of the second bearing.

3. An arrangement according to claim 2 wherein the plate has two arcuate sections located to either side of an aperture, one arcuate section being provided with retaining studs to secure the plate to the fixed element, the other arcuate section being resiliently connected to the first arcuate section and engaging both the first bearing and the second bearing.

4. An arrangement according to claim 3 wherein the first arcuate section engages both the first bearing and the second bearing.

5. An arrangement according to claim 3 wherein the arcuate sections are interconnected by two relatively narrow interconnecting bridges.

6. An arrangement according to claim 1 wherein the second retaining element is of annular form, the element carrying a plurality of radially inwardly directed resilient lugs which engage the first bearing on which the steering wheel is mounted, the second retaining element being secured to part of the steering wheel.

7. An arrangement according to claim 6 wherein the second retaining element is provided with a plurality of fixing studs, the fixing studs passing through corresponding apertures formed in part of the steering wheel.
