Description:

BACKGROUND AND SUMMARY OF THE INVENTION

This application claims the priority of German Application No. 197 24 600.1, filed Jun. 11, 1997, the disclosure of which is expressly incorporated by reference herein.

The invention relates to a motor vehicle instrument panel having a trim strip and, more particularly, to a motor vehicle instrument panel having a basic body and a trim strip which is fastened to it and extends horizontally and can be seen fromthe vehicle occupant compartment.

An instrument panel of this type is known, for example, from German Patent Document DE 33 36 934 C2. There, the trim strip is placed in a horizontally extending recess within the basic body of the instrument panel. It does not extend there inone piece over the whole width of the instrument panel. In contrast, it is, on the one hand, interrupted in the area of the steering column and does not extend, on the other hand, to the respective outermost horizontal ends of the instrument panel.

The invention relates to the problem of constructing an instrument panel provided with a horizontally arranged trim strip in a stable manner while its weight and expenditures of material are as low as possible, in which case it should be possibleto use a basic body which obtains a sufficient stability only by means of add-on pieces and its fastening within the vehicle body.

A trim strip according to the present invention contributes to the solution of this problem. The trim strip is mounted on the basic body of the instrument panel. The trim strip is constructed as a reinforcing support which covers the wholewidth of the basic body of the instrument panel, reaching form-lockingly around its ends. The reinforcing support consists of a basic aluminum part with a surface layer which is applied to it and is constructed as a wood veneer or a plastic coating. Ina manner distributed along its length, the reinforcing support is clamped and/or screwed several times to the basic body of the instrument panel. Openings for receiving instruments and/or instrument indicators are provided in the reinforcing support.

Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THEDRAWINGS

FIG. 1 is a view of a trim strip extending along the whole width of an instrument panel of a motor vehicle;

FIG. 2 is a view of the trim strip in the direction of the arrow II in FIG. 1;

FIG. 3 is a sectional view of the trim strip according to Line III--III in FIG. 2 with an area of the instrument panel basic body indicated by a dash-dotted line;

FIG. 4 is a sectional view of a trim strip according to Line IV--IV in FIG. 2 with an area of the instrument panel basic body indicated by a dash-dotted line.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to the Figures, a basic body 1 made, for example, of plastic or sheet metal material--only partially indicated in the sectional views of drawing FIGS. 3 and 4--forms the instrument panel of a motor vehicle. A reinforcing support 3,which operates as a trim strip, is fastened in a recess 2 of the basic body 1 extending along the whole width of the instrument panel.

The reinforcing support 3 also extends along the whole width of the basic body 1 and can in each case reach around its lateral ends in a form-locking manner by means of webs bent by approximately 90.degree.. In the cross-sectional view of FIGS.3 and 4, the reinforcing support 3 has an approximately U-shaped construction. It consists of a basic aluminum part 4 onto which a wood veneer 10 can be glued on the surface visible toward the vehicle occupant compartment.

The surface of the reinforcing support 3 serving as the trim strip which is visible in FIG. 2 faces the vehicle occupant interior, while the surface illustrated in FIG. 1 shows the rear or underside.

The reinforcing support 3 is partially clipped (fastening device 6 in FIG. 3) and partially screwed (fastening device 6 in FIG. 4) to the basic body 1 of the instrument panel. The portion of the fastening device 6 which is in each case situatedon the reinforcing support 3 is a bolt which is riveted to the reinforcing support 3.

In the longitudinal center part of the reinforcing support 3, a field with side-by-side openings 7 is situated. The openings 7 are used for receiving instruments and instrument indicators. In this area, the reinforcing support 3 can bestrengthened by means of a frame 12 which is linked to it and which simultaneously serves as the support for the instruments to be mounted. For achieving a good reinforcing effect, the reinforcing frame 12 is connected, particularly in a form-lockingmanner with the reinforcing support 3 by way of, for example, a dovetail joint.

FIGS. 1 and 2 show the positions of the fastening devices 6 outside the field with the openings 7. In the area of the reinforcing support 3 with the openings 7, the connection with respect to the basic body 1 takes place by way of fasteningdevices on the above-mentioned reinforcing frame connected with the reinforcing support 3.

In the above-described manner, the reinforcing support 3 is connected several times along the whole width of the instrument panel with its basic body 1 and therefore exercises a reinforcing function with respect to the basic body.

The particular advantage of the invention is the fact that the trim strip constructed as the reinforcing support 3 in connection with the basic body 1 of the instrument panel, strengthens the instrument panel as a whole in an excellent manner. As a result, the basic body 1 of the instrument panel can be constructed to be thin-walled such that, by itself, it is in an insufficiently stable condition. The basic body 1 may therefore have a low-weight construction.

The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to personsskilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
