A pressure switch strip assembly for use with a motorized chair having user-supporting elements that support a user and are movable by a motor connected by a circuit to a controller. The pressure switch strip assembly includes a pair of elongate contact strips that extend over a spring in one of the user-supporting elements. The contact strips are separated by spacers in a “normally open” position that prohibits operation of the motor by the controller. Between the contact strips and the spring is a contact wire that acts as a pressure point to deflect the contact strips together. Deflection of the contact strips closes the circuit between the controller and motor, allowing control of the chair by the user resting thereon. A pair of the pressure switch strips may be spaced apart across the user-supporting element so as to detect the user in several positions on the user-supporting element.
A motorized chair having user-supporting elements that are movable relative to each other and are controllable by a user resting on the chair, said chair comprising:
A pressure switch strip assembly for use with a motorized chair having user-supporting elements that support a user resting thereon and are movable relative to each other by a motor connected by a circuit to a controller and wherein one of the user-supporting elements includes a pair of spaced supports supporting ends of a plurality of stretcher springs extending therebetween, said assembly comprising:
A method of controlling operability of a motorized chair having user-supporting elements that are movable relative to each other and are controllable by a user resting on the chair, said method comprising:
A motorized furniture piece having user-supporting elements that are movable relative to each other and are controllable by a user resting on the furniture piece, said furniture piece comprising:
