Body frame component for a motor vehicle and method of producing it
First Claim
1. A body frame component for a motor vehicle comprising a component which absorbs at least one force acting on the component with differing load or stress conditions produced within different regions of the component when the force is being absorbed, with high load or stress conditions in a first region of the component and low load or stress conditions in a second region of the component, wherein a first through hole arrangement having at least one through hole is formed in a region of low load or stress conditions of the component and a second through hole arrangement having at least one through hole formed in a second region of high load or stress conditions of the component, for the purpose of reducing the amount of material in the component and the first and second through hole arrangements are configured to provide different resistances to applied loads in accordance with stress conditions which occur in the corresponding regions.

Abstract
A body frame component is designed so that it absorbs at least one force acting on it. The specific shape of the body frame component results in differing load or stress conditions within different regions of the body frame component when the force is being absorbed. In particular, high load or stress conditions occur in a first region and low load or stress conditions occur in a second region of the component. A reduction in the weight of the body frame component is achieved by forming at least one through hole in a region of the low load or stress conditions for the purpose of reducing the amount of material in the body frame component. In producing the body frame component, the through hole is formed either before or during the shaping of flat material to produce the specific shape of the body frame component.
