MECHANICAL COMPONENT FOR MOTOR VEHICLE WITH ENERGY ABSORPTION CAPABILITY

The sill assembly for a motor vehicle includes a hollow support, a mechanical component, and holding elements. The hollow support extends along a longitudinal direction of the motor vehicle and defines a cavity. The mechanical component is disposed within the cavity of the hollow support. The mechanical component includes at least one reinforcing structure extending parallel to the longitudinal direction of the motor vehicle and including a strip-shaped profile having a width that extends transverse within the cavity. The holding elements are disposed within the cavity of the hollow support and secured to the mechanical component to position the mechanical component within the cavity. Each holding element has at least one form-fitting element having a shape corresponding to a form-fitting element of the hollow support to reduce the potential for rotational movement of the mechanical component relative to the hollow support. The holding elements are detached from the hollow support.
