A linkage mechanism provides motion capabilities for various chair types. For example, a linkage mechanism includes a combination of links that facilitate ottoman extension/closing and backrest recline/incline. In addition, a linkage mechanism includes a compact design that is usable with hi-leg style chairs having a relatively low seat height. A seating unit with a motorized linkage mechanism is also provided.

The present invention relates to a deployment system for a deployable sofa. The deployment system includes a deployment apparatus, and the deployment apparatus includes a bottom fixing member, a support, a swinging rod, a first multi-link rod mechanism, and a second multi-link rod mechanism, where the bottom fixing member is used to be fixedly mounted to a sofa bottom frame; the support is used to support a sofa seat; the swinging rod is rotatably connected to the support by means of the first multi-link rod mechanism, and the swinging rod is rotatably connected to the bottom fixing member by means of the second multi-link rod mechanism; the second multi-link rod mechanism is constructed to be capable of enabling the swinging rod to move approximately parallel to the bottom fixing member; and the first multi-link rod mechanism is constructed to be capable of transferring translation of the swinging rod to the support, to enable the support to move approximately parallel to the bottom fixing member. The present invention eliminates a jitter phenomenon during deployment of a deployable sofa, and a link rod mechanism is used to improve synchronicity and reduce manufacturing difficulty and maintenance fees.

A mechanical stretching device for automatically folding a movable sofa leg includes a mechanical stretching device, a switching device, and an automatic folding device. The switching device includes a handle ring (1), a handle shank (3), a handle support (6) and a handle spring (5). The automatic folding device includes an automatic rotating part (8), a rotating tube (21), a spring hanging piece (17), folding spring (10). The handle ring (1) is rotatably connected to the handle shank (3). Handle shank (3) is rotatably connected to the handle support (6). The handle support (6) is fixed on the base frame mounting plate (20). The rotating tube (21) is rotatably connected to the base frame mounting plate (20). The automatic rotating part (8) is fixed on the rotating tube (21). The spring hanging piece (17) is rotatably connected to the automatic rotating part (8).

An elevated mount chair includes: a base; a pair of arms; a seat positioned above the base between the arms; a backrest; a first ottoman; a reclining mechanism attached to the base, the seat and the backrest; and a footrest mechanism attached to the seat and the first ottoman, the footrest mechanism being coupled to the reclining mechanism. The seat includes a T-cushion positioned above a seat frame, the T-cushion having lateral wings that are positioned forward of the arms. The reclining and footrest mechanisms comprise a plurality of pivotally interconnected links configured to move the chair between an upright position, a TV position, and a fully reclined position. In moving between the upright, TV and fully reclined positions, a front portion of the seat experiences substantially no forward or rearward movement relative to the arms.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

The invention is an electromechanical stretching apparatus of a convertible sofa, which consisting of a mechanical stretching apparatus and an electric actuator, the mechanical stretching apparatus being provided with an electrically-driven connecting rod, wherein, the electric actuator consists of a motor, a motor connecting tube, a motor movable slider, and a motor head fixing part, the motor adopted is a motor with a guide rail, the motor movable slider is installed on the guide rail of the motor, the motor head is rotationally connected through a second rotor shaft to the motor head fixing part fastened on the electrically-driven connecting rod, the motor connecting tube is connected to the motor movable slider through a first rotor shaft and the motor connecting tube is fastened on the mechanical stretching apparatus. The said motor connecting tube is fastened on a linkage part of the mechanical stretching apparatus. The said first rotor shaft and the second rotor shaft are both a bolt. By changing the electronic driving device, the invention increases automaticity and comfort of the convertible sofa, and improves installation, removal, maintenance, and operation efficiency of an electric actuator of the convertible sofa.

A drive mechanism for an article of adjustable furniture, the drive mechanism having support sections, the support sections including a first support section and a second support section, an actuator mechanism, and at least one connecting mechanism, the at least one connecting mechanism includes a first arm pivotally connected to the first support section, and a second arm pivotally connected to the second support section, the first arm being pivotally connected to the second arm, in which the actuator mechanism is drivingly connected to the second support section to effect concertina-like movement between the first arm and the second arm to move the second support section relative to the first support section.

A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.

Seating furniture includes at least a first and a second linear actuator to adjust the seat part, the foot part, and the back part between the seating and the reclining position. The first linear actuator generates a linear stroke causing the back part to be adjusted relative to the seat part. The second linear actuator generates a linear stroke having at least a first and second partial stroke, The first partial stroke causes, during adjustment of the seating furniture from the seating position into the reclining position, the seat part to slide relative to the frame towards the front, and simultaneously the inclination of the seat part to be adjusted, there being no extension or retraction of the foot part relative to the seat part during this first partial stroke of the second linear actuator. The second linear actuator causes the foot part to extend relative to the seat part by a second partial stroke following the first partial stroke.

A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly.
