Abstract

A motor vehicle door and a method for producing the motor vehicle door is disclosed having a frame plate coupled to reinforcement components and at least half of all of the reinforcement components are produced as extruded profiles which are subsequently press-formed three-dimensionally. The extruded profiles have different wall thicknesses.

First claim

The invention claimed is:

1. A method for producing a motor vehicle door, comprising:
providing a motor vehicle door frame plate, wherein the door frame plate is press-formed from a light metal alloy;
extruding a profile from an aluminum alloy, wherein the extruded profile has different wall thicknesses in a longitudinal direction and/or in a transverse direction;
cutting the extruded profile at a first length to form individual extruded profile pieces;
press forming of the extruded profile piece in a three-dimensional manner to form a reinforcement component for reinforcing a region of the motor vehicle door frame plate;
stamping the reinforcement component;
perforating the stamped reinforcement component; and,
coupling the at least one reinforcement component to the motor vehicle door frame plate.

2. The method of claim 1 , further comprising annealing the extruded profile pieces.

3. The method of claim 2 , further comprising quenching said extruded profile pieces.

4. The method of claim 3 , wherein the quenched extruded profile pieces are artificially or naturally aged.

5. The method of claim 1 , further comprising welding said at least one reinforcement component to said vehicle door frame.

6. The method of claim 1 , wherein the at least one reinforcement component is riveted to the vehicle door frame plate.

7. The method of claim 1 , further comprising coupling the at least one reinforcement component to the motor vehicle door frame plate at two regions and creating a hollow space between the at least one reinforcement component and the motor vehicle door frame plate.

8. The method of claim 1 , further comprising providing a Y-shaped door impact support having a base portion and two bifurcating arms extending therefrom.

9. The method of claim 8 , wherein each bifurcating arm includes an end, and wherein the ends are flattened.
