A medical chair includes a base, a seat section, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a scissor mechanism coupled to the leg rest to extend and contract the leg rest and an actuator mounted on one end relative to the seat section and having an extendible driving end coupled to the leg rest wherein when the extendible driving end extends the extendible driving end pivots the leg rest about the pivot axis and extends the scissor mechanism.

A mechanically stretchable apparatus for a sofa and a sofa thereof are provided. The mechanically stretchable apparatus includes: a seat component, a linkage component, a back component and a leg component. The seat component further includes a base, a first rotating part, the second rotating part, and the seat linkage structure placed between the first and second rotating parts. The seat linkage structure includes a back linkage with a seat connection point, a transmission connection point, and a back connection point. The seat connection point is connected to the first rotating part. The back connection point is connected to the back component. The back component and the leg component are respectively connected to the linkage component, and the linkage component is connected to the seat linkage structure.

The present disclosure provides a movable chair support structure including a movable mechanism, a fixing support structure and a chair support structure. The movable mechanism includes a transmission component and a movable component. The chair support structure includes a chair support portion, which has a length of 500 mm to 530 mm. When the movable chair support structure is disposed on the ground, the chair support portion is inclined relative to a direction parallel to the ground. The chair support portion is pivotally connected to the movable component. The movable component is pivotally connected to the fixing support structure. The transmission component is independently pivotally connected to the chair support portion and the movable component, respectively. The transmission component rotates relative to the chair support structure and drives the movable component to move, so as to adjust a position of the chair support structure relative to the fixing support structure.

A seat assembly includes a fabric component having a seat surface and a frame including an interior segment directly attached to the fabric component. The interior segment extends from an exterior segment that has a greater flexural resistance than the interior segment.

A synchronous-tilt reclining office chair includes a seat, a backrest interconnected to the seat, and an arrangement providing a synchronous-tilt mechanism that controls synchronous movement of the backrest and seat between a normal non-reclined position and a reclined position. Recline tension provided by the arrangement is a function of a force required to compress at least one tensioning spring mounted below the seat, a weight applied on the seat by a seat occupant, and a location of the weight on the seat relative to front and rear portions of the seat, whereby, as the weight is applied toward the front portion of the seat, recline tension is reduced and, as the weight is applied toward the rear portion of the seat, recline tension is increased.

A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user. A remotely controlled powered chair may include a base assembly. A chair frame is supported on the base assembly. An actuator mechanism may communicate with the base assembly and the chair frame, and is operable to actuate the chair frame between first and second positions.

A rocker recliner is disclosed that has a pair of stationary arms; a seat disposed between the arms; an ottoman; a back coupled to the seat. A full-recline linkage mechanism couples the ottoman, the seat and the back and is operable to move the ottoman, the seat and the back between a closed position, a TV position and a fully reclined position. A rocker assembly is coupled between the full-recline linkage mechanism and the stationary arms that allows the seat, back and ottoman to rock between the stationary arms in any of the closed position, the TV position or the fully reclined position.

A motorized positioning apparatus for a seating unit includes a motor assembly that is configured to move a pair of linkage mechanisms though a series of positions that arrange the seating unit in a closed position, open position, or extended position. The motor assembly is selectively and releasably coupled to the linkage mechanisms, to allow the motor assembly to be de-coupled from the linkage mechanisms to allow the seating unit to be manually closed by a user.
