Abstract: A body component arrangement for a motor vehicle includes a body component having a specific shape which under the action of an applied force has different load and/or stress conditions within different regions of the body component including high load and/or stress conditions in a first region and lower load and/or stress conditions in a second region. A pattern of through holes is provided so that the through holes in the region of the lower load and/or stress conditions form a perforation pattern having a configuration arranged so that the load and/or stress conditions arising in that region under the action of an applied force will have a substantially uniform distribution. This produces a weight saving that is very economical and achieves a reduction of damage in the region of lower load and/or stress conditions.

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.

Abstract: An adjustment arrangement for at least two rear view mirrors of a vehicle has servo motors for positioning rear view mirrors by a pivoting and/or tilting mechanism, an actuating device for generating control signals for the common activation of the servo motors and a signal transmission device for transmitting signals between the actuating device and the servo motors. To carry out common adjustment of at least two mirrors with a mechanically simple system, the adjusting arrangement is configured so that the same control signal can be fed to the appropriate servo motors for the mirrors by the signal transmission device. During the adjustment action, the movements of the mirrors are in a predetermined relationship with one another.
