Abstract: A recliner mechanism includes a base. Returning spring units are disposed on two sides of the base and rockers are disposed on outer sides of the returning spring units. An extending assembly is disposed at the top of each rocker. A drive unit is arranged between the extending assemblies on the two sides and includes a front driving rod. A reciprocating device is disposed at the middle of the front driving rod and a rear driving rod is disposed at an output end of the reciprocating device. Bent members are fixedly connected to two ends of the rear driving rod. Each bent member is pivotally coupled with a driving member I and the middle of the driving member I is pivotally coupled with a driving member II, with the other ends of the driving member I and the driving member II being pivotally coupled with the extending assemblies.

Abstract: An electrical mechanical stretching device of a movable sofa includes a mechanical stretching device and an electrical device, wherein the mechanical stretching device includes a third leg rod and a third connecting rod. The electrical device consists of a motor sliding block connecting pipe, a motor, a motor leg fixing pipe, a motor guide rail and a motor sliding block. The motor is provided with the motor guide rail. The motor sliding block is mounted on the motor guide rail. A motor end is rotatably connected via a second rotating shaft to the motor leg fixing pipe which is fixed on the third leg rod. The motor sliding block is rotatably connected via a first rotating shaft to the motor sliding block connecting pipe which is fixed on the third connecting rod. A base of the mechanical stretching device is connected by two bottom connecting pipes.

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.
