IMPACT ABSORBER

摘要

Disclosed is an impact absorber with which the energy absorption characteristics during a collision can be set to specific characteristics. An impact absorber (1) for a motor vehicle is provided between a body panel and an interior member of the motor vehicle, and absorbs impact energy from a collision. The impact absorber comprises a base (2) which is fixed between the body panel and the interior member, and a plurality of protrusions (3) which protrude from the base and have the shape of a hollow cone or a truncated cone. The heights of the plurality of protrusions are not the same, and there are protrusions present which have differing numbers of ribs (4) constituting linear projections which project from the outer peripheral surface of said protrusions and are oriented from the tip ends of the protrusions towards the bases thereof. The ribs do not link adjacent protrusions, and are not disposed on a line joining the centres of adjacent protrusions.
