  • MOTORIZED FURNITURE HEADREST ASSEMBLY FOR SEATING SYSTEMS
    Publication number: 20190167004
    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.
    Type: Application
