Abstract

An extrusion made from metal or plastic extends along the siderail of a vehicle and acts as a head impact countermeasure, and in the preferred embodiment as a platform for the attachment of any of a variety of siderail attachments, such as grab handles, coat hooks, visor tracks, etc. The components can be attached in a way which permits them to slide to the appropriate position and be locked into place. The hollow interior of the extrusion can be used to house additional safety components, such as a side air bag.
