Abstract
Official abstract text for this publication.
Systems and other embodiments described herein relate to vehicle collision energy absorption with increased airflow towards an engine compartment of a vehicle. In one embodiment, the system includes a front energy absorber with a first top surface having an angle and a rear energy absorber with a second top surface that is curved. The rear energy absorber is separated from the front energy absorber by a gap and a plane of the first top surface is tangential to the second top surface.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle energy absorption system, comprising: a front energy absorber with a first top surface having an angle; and a rear energy absorber with a second top surface that is curved, the rear energy absorber is separated from the front energy absorber by a gap and a plane of the first top surface is tangential to the second top surface. 2 . The vehicle energy absorption system of claim 1 , wherein the front energy absorber extends below and in front of the rear energy absorber in a vehicle length direction. 3 . The vehicle energy absorption system of claim 1 , further comprising a rib formed on a back surface of the front energy absorber, wherein the rib is transverse to a vehicle length direction. 4 . The vehicle energy absorption system of claim 3 , wherein: the rib and first top surface form a notch in the front energy absorber; a front surface of the rear energy absorber is separated from the first top surface by a vertical portion of the gap; and a bottom surface of the rear energy absorber is separated from the rib by a horizontal portion of the gap. 5 . The vehicle energy absorption system of claim 1 , wherein the front energy absorber further comprises: a vertical front surface; and a downward-sloping bottom surface such that the front energy absorber has a convex profile in a vehicle length direction. 6 . The vehicle energy absorption system of claim 1 , wherein the rear energy absorber and the front energy absorber are individually attachable to a frame of a vehicle. 7 . The vehicle energy absorption system of claim 1 , wherein the rear energy absorber is stiffer than the front energy absorber. 8 . The vehicle energy absorption system of claim 1 , wherein the rear energy absorber and the front energy absorber are formed of different materials. 9 . The vehicle energy absorption system of claim 7 , wherein: the rear energy absorber is formed of a first foam having a first density; and the front energy absorber is formed of a second foam having a second density that is less than the first density. 10 . The vehicle energy absorption system of claim 1 , wherein an upper portion of the front energy absorber overlaps a lower portion of the rear energy absorber in a vehicle length direction.
