Abstract

A head restraint assembly includes a curved support member for upwardly and forwardly deploying a headrest. The support member is selectively locked and unlocked to alternately maintain the headrest in a retracted position or deploy the headrest. A vehicle impact sensor signals the release of the support member when a vehicle impact is sensed. The headrest is deployed quickly and effectively until it reaches its potential full deployment, or until an occupant's head contacts the headrest.
