Abstract
A motorized furniture headrest assembly includes a headrest actuator and roller track that minimizes effort of a motor to impart angular movement of an associated headrest support mechanism. The roller track is curvilinear with a non-constant radius of curvature. The actuator and roller track are disposed sufficiently close to a center line of the headrest support mechanism to achieve angular actuation of the headrest support mechanism without one side of the headrest support mechanism lagging behind the other during angular movement.
Claims11
A motorized headrest assembly, comprising:
- an actuator assembly including a receiver housing, a motor, a piston arm having a first end received in the receiver housing, and a roller housing disposed at an end of the piston arm opposite the end of the piston arm received in the receiver housing, the roller housing including a rotatably mounted roller wheel;
- and
- a curvilinear track bracket including a curvilinear track having a non-constant radius of curvature, the curvilinear track bracket secured to a portion of a headrest support mechanism and engaging the roller wheel.
