Description

The invention relates to a steering wheel assembly for motor vehicles according to the preamble of Claim 1.

Steering wheel assemblies (see GB-PS 11 52 294) are already known in a large number of embodiments Steering wheel directly over the steering shaft, which contains a grid-like, collapsible steering shaft part Steering gear supported on the body. In another of these embodiments, the steering wheel is over a steering column comprising the collapsible steering shaft, which is a lattice-shaped or tubular, corrugated, Contains collapsible component, supported on the bulkhead of the body

These known steering wheel assemblies have the disadvantage that they are difficult to manufacture and assemble are relatively expensive and that their function deviates from the axis of the steering column Direction of impact is insufficient.

There are still according to DE-PS 9 44 350 on the body! Detachably attached, in the passenger compartment protruding support parts for hanging pedals of clutch and brake known that a simple Allow preassembly of the lever and cylinder assemblies for these actuation parts outside the vehicle, so that in the final assembly only the preassembled support part quickly and easily to the Body must be attached.

The object of the invention is, in a steering wheel assembly according to the generic term Increase accident safety.

According to the invention, this object is achieved by the characterizing features of claim 1

The steering wheel assembly according to the invention has the advantage that by combining with the preassembled support part in production and assembly is easier and that by supporting the Steering wheel on the plustically deformable support part, the cross section of which is significantly larger than that a steering column jacket tube can be selected, a satisfactory functionality even with from the axis of the steering shaft repelling direction of impact is guaranteed.

The invention is explained in more detail with reference to two exemplary embodiments shown in the drawings. It shows

F i g. 1 a perspective view of a support part,

F i g. 2 is a perspective view of a steering wheel with one for cooperation with the support part according to FIG. 1 trained steering shaft,

F i g. 3 is a perspective view of a preferred embodiment;

4 shows a side view of the embodiment according to FIG. 3,

F i g. 5 and 6 are perspective views of different exemplary embodiments for the central area a support part according to FIG. 3.

In Fig. 1 and 2 a simple embodiment of the invention is shown. A support part 10 is via flanges 11 attached to the lower part of the bulkhead of a motor vehicle body. Clutch and brake pedals (not shown) are arranged hanging on a bearing axis to, which extends through openings 12 in the support part extends.

The upper part 13 of a collapsible steering shaft is connected to a steering wheel 14 and extends through an opening 15 in the end wall 16 of the support part 10. The upper part 13 of the steering shaft is connected to a baffle plate 17, which in the assembled state of the steering wheel assembly just above the End wall 16 of the support part 10 is located.

A lower part of the steering shaft connects the upper part 13 of the steering shaft to a steering gear. the upper and lower steering shaft parts can be axially pushed together in a conventional manner. This axial It can be pushed together by connecting the lower and upper parts of the steering shaft via shear pins or by using a flexible cable as the lower steering shaft part.

For this purpose 3 sheets of drawings

Claims (3)

Patent claims: 1. Steering wheel assembly for motor vehicles with a steering column assembly below the Steering wheel partially comprehensive, to accommodate monitoring devices and control rods (e.g .: pedals) at the bottom of the bulkhead and at the top of the dashboard of the Body-supported or fixed, pre-assemblable supporting part, characterized in that dai the support part (10 or 20) at its upper end (end wall 16 or end part 23) one of these penetrating, upper part (13) of a steering shaft which can be pushed together in a manner known per se and the supporting part (10 or 20) plastically in the evasive direction of the steering wheel (14 or 31) Is designed to be deformable 2. Steering wheel arrangement according to claim 1, characterized in that the support part (20) in the direction the steering shaft (30) extended and the steering shaft (30) immediately behind the steering wheel (31) in the end part (23) of the support part (20) is mounted or supported and the support part (20) has a central area (22) which is designed to be plastically deformable. 3. Steering wheel assembly according to claim 2, characterized in that the elongated end part (23) of the Support part (20) on the body via a release in the evasive direction of the steering wheel (31) Retaining plate (29) is attached.
