Abstract

An intermediate shell for a motor vehicle door, in particular a side door of a motor vehicle, is disclosed. The intermediate shell is produced at least in regions from a light metal blank by massive forming, preferably by forging.

First claim

The invention claimed is:

1. A method for producing an intermediate shell for a side door of a motor vehicle, comprising the steps of:
producing the intermediate shell in one piece from a metal blank by forging, wherein the intermediate shell includes a lower frame part, a window frame, and a belt line;
locally adjusting a mechanical strength in the intermediate shell in a region by collecting fibers in the region during the forging, wherein the mechanical strength of the region is greater than a mechanical strength of another region of the intermediate shell; and
forging on the intermediate shell a side impact brace and a connection element.

2. The method according to claim 1 , wherein the metal blank is a metal alloy.
