Abstract

A front wall module for delimiting a front of a passenger cell in a motor vehicle includes a planar carrier structure which forms a front wall portion where a functional shape for receiving a component is formed in the planar carrier structure and where the planar carrier structure is a cast aluminum structural part.

First claim

What is claimed is:

1. A front wall module for delimiting a front of a passenger cell in a motor vehicle, comprising:
a planar carrier structure which forms a front wall portion, wherein a first functional shape for receiving a first component is formed in the planar carrier structure and wherein the planar carrier structure is a cast aluminum structural part;
wherein a plastics body is injection-molded onto the planar carrier structure;
wherein the plastics body is formed from foamed plastic and is acoustic insulation;
wherein a second functional shape is integrated into the plastics body for receiving a second component or wherein the plastics body forms a second functional shape for receiving a second component.

2. The front wall module according to claim 1 , wherein the planar carrier structure is a foamed cast aluminum structural part.

3. The front wall module according to claim 1 , wherein the planar carrier structure has respective greater wall thicknesses in portions of high expected structural part loading than in portions of low expected structural part loading.

4. The front wall module according to claim 1 , wherein the planar carrier structure has reinforcing ribs.

5. The front wall module according to claim 1 , wherein the planar carrier structure has a peripheral flange for attaching to a body of the motor vehicle.

6. The front wall module according to claim 1 , wherein a bearing block for a foot lever mechanism is integrated into the planar carrier structure.

7. The front wall module according to claim 1 , wherein the planar carrier structure and/or the plastics body is configured such that the front wall module performs a function of an instrument panel support.

8. A method of forming a front wall module that delimits a front of a passenger cell in a motor vehicle, comprising the step of:
forming a planar carrier structure by a casting method, wherein a functional shape for receiving a component is formed in the planar carrier structure and wherein the planar carrier structure is aluminum; and
injection-molding a plastics body onto the planar carrier structure;
wherein the plastics body is formed from foamed plastic and is acoustic insulation;
wherein a second functional shape is integrated into the plastics body for receiving a second component or wherein the plastics body forms a second functional shape for receiving a second component.
