Abstract

A head restraint assembly includes a support member and a deployable member selectively movable between a retracted position and a deployed position. At least a portion of the deployable member is farther from the support member in the deployed than in the retracted position. A latch system is configured to releasably retain the deployable member in its retracted position. An active material member is actuatable to release the latch system, to release the deployable member.
