ABSTRACT:
An impact absorber for a vehicle includes an outer body including a cavity having an axis, and an inner body situated partially within the cavity for relative movement into the cavity when the absorber is subjected to an impact. The inner body has at least one lateral protrusion. A number of deformable units are located in the outer body at different positions along the cavity. The deformable units partially protrude into the cavity for successive engagements and deformations, one unit after another unit, along the cavity, by the protrusion of the inner body moving into the outer body, thereby absorbing the energy of an impact in different stages. Each deformable unit includes a rigid ball protruding into the cavity and a deformable plate fixed behind the ball.
