Abstract
An energy absorber for protecting the occupants of a vehicle. The energy absorber includes an interior portion and a first contact surface at least partially surrounding the interior portion. The first contact surface is attachable to a structural member of the vehicle. The energy absorber also includes at least one hollow cavity extending through the interior portion in a direction substantially parallel to the first contact surface. During a vehicle collision, the first contact surface absorbs energy from occupant impact with an interior trim piece by deforming into the hollow cavity.
