A roof-mounted energy absorbing countermeasure system for use in a vehicle is provided. In one example, the system may include an impact detection module configured to detect whether a vehicle has experienced an impact and generate an impact detection signal in response thereto. The system may also include a countermeasure disposed between an outer roof panel of the vehicle and an inner roof panel of the vehicle. The outer roof panel and the inner roof panel may be separated by a first distance in a pre-impact state. The countermeasure may eb configured to deploy, in response to generation of the impact detection signal, so as to cause at least a portion of the outer roof panel and at least a portion of the inner roof panel to be separated by a second distance that is greater than the first distance.

An impact absorber to be mounted between a vehicular panel and a vehicular interior part covering the vehicular panel from a vehicular interior side includes an opposite wall to be opposite the vehicular panel, outer walls extending from edges of the opposite wall toward a vehicular interior side, and an extended wall extending from the opposite wall toward the vehicular interior side and having a side edge connected to the one outer wall, and the extended wall having a thickness that is increased from a vehicular interior end thereof toward a vehicular exterior end thereof, and the extended wall having a cutout hole that is open toward a vehicular exterior side.

An impact absorber to be mounted on a vehicular exterior side surface of a vehicular interior part covering a vehicular panel from a vehicular interior side includes an opposite wall to be opposite the vehicular panel, outer walls extending from edges of the opposite wall toward a vehicular interior side, and mounting portions that are to be fit to mount members included on the vehicular exterior side surface of the vehicular interior part, each of the mounting portions including a basal portion being included at a vehicular interior side end of one of the outer walls and in contact with the vehicular exterior side surface of the vehicular interior part, a distal end portion being on a vehicular exterior side than the basal portion and to be secured to one of the mount members, and an intermediate portion connecting the basal portion and the distal end portion.

A shock absorbing structure of a vehicle door including a vehicle body panel with a service hole includes a door trim and a shock absorber. The door trim covers the vehicle body panel from an interior side of a vehicle. The shock absorber is mounted to the vehicle body panel to cover the service hole. The shock absorber includes a shock absorbing portion that is inserted in the service hole. The shock absorbing portion is disposed such that an end of the shock absorbing portion on an exterior side of the vehicle is disposed more to the exterior side of the vehicle than the service hole and between the vehicle body panel and the door trim.

An assembly includes a door trim panel, and an armrest assembly supported by the door trim panel. The armrest assembly includes a crushable member. The crushable member includes a substrate defining a gap extending through the substrate. The crushable member includes a plug disposed in the gap and fixed to the substrate on a perimeter of the gap. The substrate is rigid relative to the plug.

A side pillar air curtain guide includes a main body having a ramp receiver and an air curtain ramp insert connected to the ramp receiver. The main body is made from a first material having a strength S.sub.1 and a ductility D.sub.1 while the air curtain ramp insert is made from a second material having a strength S.sub.2 and a ductility D.sub.2 where S.sub.1>S.sub.2 and D.sub.1<D.sub.2.
