It is an object of the invention to provide a support part for holding a vehicle data display unit, a navigation unit and a radio unit. It is a further object of the invention to provide a support part to ensure that the units and air outlets are held centrally with a reduction of joint tolerances between the components.

SUMMARY OF THE INVENTION

The invention relates to a support part formed as a structure-reinforcing component of the instrument panel and with a receptacle and centering means for the unit and the air outlets. The support part comprises an integral or unitary frame with a central holding frame for the unit and laterally adjoining holding frames for the air outlets. The support part is connected at one side to the instrument panel and at the other side to a cockpit cross. Centering receptacles for the unit and further centering receptacles for the air outlets are arranged in the central holding frame and in the two lateral holding frames.

The frame of the support part preferably has at least four fastenings to the instrument panel on a top frame section of the central and lateral holding frames and at least two further fastenings on a lower outer frame section of the lateral holding frames. Fastening angle brackets are arranged on the lateral holding frames in the lower outer frame section and can be connected to the cockpit cross member. The fastening angle brackets preferably are arranged with a gap clearance to the lateral outer frame section and attached at the top side with a limb to the holding frame.

The unit preferably is fastened and securely positioned to the central holding frame at least at four fastening points arranged in corner points of the frame. The support part thus is fixed both to the instrument panel and to the cockpit cross member to ensure a stable attachment and to reinforce the structure of the instrument panel. The attachment of the fastening angle bracket with a gap clearance to the lateral holding frame obtains a certain weakening of the attachment and achieves a reduction in the head impact values.

Opposite centering receptacles for centering elements of the unit are arranged at the inside in lateral walls in the central holding frame of the support part to hold the unit centrally. The centering receptacles comprise U-shaped slide-in grooves that run in the longitudinal direction of the holding frame and that position the unit in the vertical direction (z direction). The U-shaped centering receptacles enable the unit to be pushed into the support part from the front, and the centering elements hold the unit precisely in the vertical direction.

A molding preferably is arranged on the top edge and has a centering receptacle that receives a centering element of the unit for further centering the unit in the central holding frame. The centering receptacle holds the unit in position in the transverse direction (y direction). Furthermore, a downwardly projecting bracket preferably is formed integrally on the bottom edge section of the central holding frame. The bracket has a rectangular slot opening arranged to receive a positioning pin on a central console of the instrument panel. The positioning pin projects in a retentive fashion into the slot opening and holds the unit centered in the vehicle transverse direction (y direction). Thus, the central console of the instrument panel is centered with respect to the support part to achieve a precise alignment of the two components with respect to one another.

Centering receptacles for the air outlets preferably are formed integrally on a side wall of the central holding frame so that the air outlets can be inserted with a precise joint dimension. The centering receptacles comprise an upper opening and a groove-like depression arranged therebelow. Centering elements project in the vertical direction (z direction) and in the longitudinal direction (x direction) of the air outlet and engage the centering receptacles to position the air outlets.

The centering elements for the air outlets may comprise two spaced-apart cams arranged on the wall opposite the side wall or on the frame section of the lateral holding frame. The cams engage into recesses or some other receptacles on the air outlet and accurately position the air outlet in the transverse direction (y direction). The centering elements enable optimum alignment in the support part and in the lateral holding frames in all directions.

U-shaped centering lugs preferably are provided on the outer frame of the unit for accurately positioning the air outlets The centering lugs are inserted in and held by a frame of the air outlets. Furthermore, the air outlets are held by latching connections or spring clamps with the support part in the lateral holding frame.

An exemplary embodiment of the invention is illustrated in the drawings and is described in more detail below.
