摘要： 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.

摘要： A reconfigurable apparatus for sitting and having a seat mounted on a frame and movable under the weight of a sitting user. As an incident of the user sitting, resistance to movement of a back rest component is increased a predetermined amount based upon the user's weight. A manually operable subassembly allows the increased resistance to be changed from the predetermined amount with the user sitting on the seat.

摘要： An adjustable and angled seat assembly having a base supportable on a ground surface, a wedge support member with a wedge length separating the front and rear ends thereon and a wedge height separating upper and lower ends thereon, with the lower end directly coupled to a support plate and tapering in the wedge height spanning along the wedge length to define a wedge angle θ defined by the upper and lower ends of the wedge support member. The assembly also includes a seat cushion having a seat-support surface disposed above the base and a seat-support angle relative to the base support plane and a lower surface directly coupled to the upper 704 of the wedge support member and a chest cushion having a chest-support surface disposed above the seat-support surface, coupled to the support plate, and disposed at an at an acute angle with respect to the seat-support surface.

摘要： 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.

摘要： A tiltable chair includes a flexible seat body including an integrally formed seat back and seat surface is supported on a seat frame disposed on upper parts of legs, and the seat back connected to a back frame allowing tilting rearwards, the position of the connection being in an area around the upper part of the pelvis of a person seated thereon. A guide rail having an arc-shaped groove is fixed to the seat frame, and guide members which engage and roll in the arc-shaped grooves are pivotably supported on a shaft bracket of the rear surface of the seat surface. The arc-shaped groove has a high center so that the seat surface undergoes curved motion forward and upward such that the ischium is positioned lower than the lower part of the knees when the seat back tilts rearwards.

摘要： A chair that provides movement side-to-side about a first pivot axis positioned above the seat plane allows the user a wide range of dynamic movement, but does not require constant or excessive action on the part of the user to maintain a desired position. In addition and concurrently thereto, the chair may include structures that allow the seat to be easily positioned and adjusted side-to-side from a neutral position along a defined pivot axis above a seat plane, and it may, if desired, also provide forward-and-back movement of the seat about a second pivot located above or below the seat plane, an improved seatback that supports the user's back without limiting the user's ability to move their shoulder blades, an improved biasing structure for biasing the seat to a neutral position, an imbedded controller or imbedded sensor for allowing the seat's position to be used as a computer controller, or the gathering of the users motion data, and an adjustable tilt locking system to allow the forward-and-back movement of the seat to be held in a desired position.
