Active material actuated headrest assemblies
First Claim
Patent Images
1. A method of selectively reconfiguring a headrest extending from a seatback, the method comprising:
- activating an active material with an activation signal, wherein the active material is in operative communication with a headrest surface located at a first position and defining a first modulus property, and the material is operable to undergo a reversible change in at least one physical or chemical property upon receipt of the activation signal; and
modifying the position or modulus property as a result of the change in the at least one property of the material,autonomously restoring the surface or enabling the surface to be restored to the first position or the first modulus property by deactivating the material.

Abstract
A headrest assembly including active material drivenly coupled to a headrest component, such as for example, an interior frame member, bag, or gear device wherein the material is actuated upon receipt of an activation signal, and configured to morph, reposition, reduce the resistance of, change a modulus property of, or otherwise modify an engaging surface defined by the headrest when actuated, and autonomously restore the headrest upon the deactivation of the material.
