ABSTRACT:
A recliner adjustment system and method utilizing active material based actuation is adapted for use with a recliner defining an engaging surface and operable to adjust the angle of inclination of the surface, and includes a locking mechanism configured to selectively prevent the surface from pivoting, an unlocking actuator including at least one active material element configured to release the mechanism when activated or deactivated, a signal source operable to generate and deliver to the element an activation signal, and more preferably, a second adjusting actuator including a second active material element configured to rotationally displace the surface, so as to adjust the angle, when activated or deactivated and the mechanism has been released.
