Self-supporting plastic construction part for use in air guidance part utilized to guide e.g. cooling air, in engine compartment of motor vehicle, has extension part provided for vehicle, where line extends over area of construction part

摘要

The construction part (2) has a planar extension part provided for a motor vehicle. A target deformation line (5) extends over an entire area of the construction part, where wall thickness of the construction part is locally reduced at the target deformation line. A material composition of the construction part is locally varied at the target deformation line. Height of a stage is larger than the wall thickness of the construction part beside the target deformation line. The target deformation line is passed transverse to a longitudinal axis (6) of the motor vehicle.
