Abstract: An apron for a vehicle front end comprises a unitary plastic component having a front structure and a rear structure joined by an offset portion. The front and rear structures extend at rearward downward angles and in generally parallel directions, and the offset portion extends at a rearward upward angle. The apron has a relatively constant vertical dimension, such that the angled structures define a wave-shaped envelope. Preferably, a horizontal plane extending from the tip of the front structure stays within the wave-shaped envelope, so that impact forces stay within the boundary in a manner providing improved impact strength and greater energy absorption during an impact. At the same time, the front structure provides a homogeneous structure that distributes local impact stresses uniformly and more widely into the rear structure, thus providing a more uniform impact resistance less sensitive to impact location.

Abstract translation: 用于车辆前端的挡板包括具有前部结构的整体塑料部件和由偏移部分连接的后部结构。 前后结构以向后的角度和大致平行的方向延伸，并且偏移部分以向后的向上的角度延伸。 围裙具有相对恒定的垂直尺寸，使得倾斜结构限定波形包络。 优选地，从前结构的尖端延伸的水平面保持在波形外壳内，使得冲击力以提供冲击强度和在冲击期间更大的能量吸收的方式保持在边界内。 同时，前部结构提供均匀的结构，其将局部冲击应力均匀地并且更广泛地分布到后部结构中，从而提供对冲击位置较不敏感的更均匀的冲击阻力。
