摘要： A pivot fitting has a first lever mounted such that is pivotable out of a starting position about a force-transmitting shaft serving as an axis of rotation in relation to the shaft. The fitting has a clamping mechanism fixing the first lever in different angular positions relative to the shaft. The clamping mechanism has a toothed-ring disc positioned on the shaft and has an outer toothing structure formed on the outer periphery, a catch mounted in a pivotable manner on the first lever and is loaded in the direction of the outer toothing structure and, in a latching position, is in engagement with the outer toothing structure. A first control disc is mounted in a rotatable manner about the shaft so that following movement through the predetermined angle out of the starting position in an adjustment direction, the catch is disengaged from the outer toothing structure, and with the catch disengaged from the outer toothing structure it is possible for the first lever to be pivoted back relative to the shaft into the starting position.

摘要： A power leisure reclining chair includes a seat structure having a seat portion and a backrest portion, a support assembly having two wooden leg assemblies connected by a wooden cross beam, and a main push rod positioned between the seat structure and the cross beam to push the seat structure to swing. A metal frame and an armrest are arranged on the leg assembly. The support assembly has metal bars extending from a pivot pin on each leg assembly and connecting the seat portion. The metal bar is pivoted to the metal frame. The backrest portion is held at the rear of the leg assemblies by a rail guide system. The rail guide system has guide elements fixed to the leg assembly, and rail member fixed to the backrest portion. The guide element has an under and a top bearing against the bottom and side of the rail member.

摘要： A gliding reclining seating unit includes: a base; a frame with opposed arms; a gliding mechanism attached to the frame and the base, the gliding mechanism configured to enable the frame to glide longitudinally relative to the base; a seat; a backrest; an ottoman; a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the frame, seat, backrest and ottoman, the reclining mechanism being configured to move the seating unit between an upright position, an intermediate TV position, and (c) a fully reclined position; and a glide stop unit that prevents the frame from gliding rearwardly relative to the base when the seating unit is in the TV and fully reclined positions. The seating unit is actuated for movement from the upright position to the TV position via an occupant of the chair pushing on the arms of the frame.

摘要： A reclining seating unit includes: a frame configured to rest on an underlying surface; a generally horizontally-disposed seat; a generally upright backrest positioned rearwardly of the seat; a footrest unit; and a reclining mechanism that interconnects and controls the relative movement of the frame, the seat and the backrest between an upright position and a reclined position. In the upright position, the backrest is generally upright and positioned above the frame, and the seat has a first rearward position relative to the frame. In the reclined position, the backrest is reclined relative to the underlying surface as compared to its disposition in the upright position and the seat has a second forward position relative to the frame that is forward of the first rearward position. The footrest unit comprises at least one footrest and a footrest mechanism that interconnects the footrest with the seat. The footrest mechanism is configured to move the ottoman between a retracted position, in which the footrest is positioned beneath the seat, and an extended position, in which the footrest is generally horizontally disposed in front of the seat. When the backrest moves between the upright and reclined positions, the footrest unit moves in concert with the seat.

摘要： A furniture member having powered rocking motion includes a frame and an actuation mechanism rotatably connected to the frame and movable in forward and rearward rocking motions with respect to the frame. A powered rocking drive device includes a motor connected to the actuation mechanism and a solenoid. The solenoid when energized releasably couples the motor to the frame such that operation of the motor automatically induces the forward and rearward rocking motions of the actuation mechanism. The solenoid when de-energized decouples the motor from the frame permitting an occupant to induce the forward and rearward rocking motions of the actuation mechanism with respect to the frame.

摘要： The present invention is a chair having a first seat portion operably associated with a second seat portion, with the first seat portion disposed in the same plane as the second seat portion when the chair is in a lowered position, and an actuator for moving the first seat portion relative to the second seat portion. When the actuator is actuated, the first seat portion pivots relative to the second seat portion such that the first seat portion is located in a different plane compared to the second seat portion. When in the raised position, the first seat portion is substantially parallel to the ground, which allows the occupant of the chair to easily transfer the occupant's center of gravity to being supported by the occupant's feet and knees.
