1. A recliner adapted for supporting an object, and to autonomously determine an obstacle to adjustment, said recliner comprising:

  • a base configured to support the object;

    a structural member configured to further support the object, and pivotally connected to the base, such that the base and member cooperatively define an angle of inclination therebetween;

    a power adjustment system configured to autonomously adjust the angle, when actuated; and

    at least one sensor secured relative to the base or member, operable to detect the presence of the object, and including an active material element operable to undergo a change in at least one attribute when exposed to an activation signal or when exposure to the signal is discontinued, wherein detection of the object is caused by the change,said sensor being communicatively coupled to, and configured to selectively prevent actuation of the system, when the object is detected.
