Patent ID: 7963600

Claim:
A method for selectively deploying a head restraint assembly comprising: activating an active material member with an activation signal, wherein the active material member includes a first end and a second end in operative communication with a support member, and wherein the active material member is configured to undergo a change in at least one property between the first end and the second end upon receipt of the activation signal; and said change in at least one property between the first end and the second end of the active material member thereby actuating a deployable member to move from a retracted position to a deployed position to deploy the head restraint assembly; wherein actuating the deployable member to move from the retracted position to the deployed position to deploy the head restraint assembly includes: rotating a first link rotatably mounted to the support member and the deployable member to thereby move the deployable member from the retracted position to the deployed position; rotating a second link rotatably mounted to the deployable member and a clutch assembly when the deployable member moves from the retracted position to the deployed position; and sliding a clutch along a rod mounted with respect to the support member when the second link is rotated.
