Patent ID: 7562929

Claim:
A deformation element for absorbing lateral impact forces in a lateral region of a motor vehicle, the deformation element comprising: a deformation body having at least three hollow chambers formed therein and disposed one behind another in a direction of action of the lateral impact forces, said deformation body having undulated side walls of an undulating configuration for forming said hollow chambers with different cross-sectional profiles, one of said three hollow chambers being an inner hollow chamber facing a motor vehicle interior, one of said three hollow chambers being an outer hollow chamber facing a vehicle exterior, and one of said three hollow chambers being a central hollow chamber disposed between said outer and said inner hollow chambers, an axial extension of said hollow chambers being oriented approximately at right angles to the direction of action of the lateral impact forces; and at least one fastening portion for mounting said deformation body on an associated lateral sill portion of the motor vehicle, said fastening portion extending from said deformation body.
