The invention relates to a piece of seating and supporting furniture with a seating and supporting body, comprising: a height-adjustable column; a seating and supporting body, which is mounted pivotably about at least one horizontal axis between a first end position and a second end position at a first end of the height-adjustable column; a stopping mechanism, which is situated at a second end of the height-adjustable column; and a locking mechanism for releasably locking the stopping mechanism. A seating and supporting piece of furniture which allows reliable and user-friendly operation is created according to the invention in that a transfer device is used to release the locking of the stopping mechanism by the locking mechanism via the pivoting of the seating and supporting body between the first end position and the second end position.

An office-type chair includes a base, a height-adjustable pedestal extending upward from the base, a seat assembly including a rear seat part and a front seat part, and a linkage system connecting the pedestal to the seat assembly. The linkage system is adapted to pivot the seat assembly between a lowered position to serve as a task chair and an elevated position to serve as an elevated sitting support. A backrest arrangement may extend from the seat assembly. In the lowered position, the front and rear seat parts are both generally horizontally oriented. In the elevated position, the rear seat part may have a slight forward tilt and be positioned higher than in the lowered position, and the front seat part may extend at a downward angle relative to the rear seat part.

Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

A seating support device of a wearable chair includes a femoral link extending in a direction where a femoral region extends and configured to be connected with the femoral region, a crural link extending in a direction where a crural region extends, and configured to be connected with the crural region, and including a housing that is coupled at an upper end thereof to a lower end of the femoral link to be rotatable relative thereto and a sliding part that is slidably coupled to the housing in a direction in which the housing extends, and a limiting device operated in conjunction with a relative rotation between the femoral link and the crural link to allow the sliding part to slide vertically and to prevent sliding between the sliding part and the housing in a state where an angle between the femoral link and the crural link is a seating angle.

A wearable chair includes: a thigh link extending in an extension direction of a wearer's thigh to be connected to the wearer's thigh; a crus link extending in an extension direction of the wearer's crus to be connected to the wearer's crus, having an upper end portion rotatably coupled to a lower end portion of the thigh link, and prevented from rotating such that an angle between the crus link and the thigh link is less than a sitting angle; and a contact link having a first end rotatably coupled to a lower end portion of the crus link and a second end coming in contact with the ground at a predetermined position from the crus link by rotating with respect to the first end with relative rotation between the thigh link and the crus link when the wearer is in a sitting position.

A seating device employing an interaction of components to include an engineered multi surface rear stabilizer component comprised of a rotatable object engagement piece working in conjunction with an adjustable support piece granting the ability to lock in position by means of a binding style fastener. This multi surface rear stabilizer is mounted to one end of a two-piece sleeve type, length adjustable trunk, capable of four-sided rotation granting the center fulcrum design of the foot piece to be employed in any direction as well as the closed position. This device employs a rotatably connected seat to a swing arm style piece connected to the trunk granting the ability to incrementally adjust from parallel to perpendicular to the associated trunk.

A seating apparatus for supporting a portion of a user, the seating apparatus comprising a reorientable seat portion including a seat platform and a cutout, wherein the seat selectively underlies a first ischial tuberosity of the user but not the second ischial tuberosity, the selection of which is determined by the orientation of the reorientable seat portion.

An assistive device for standing tasks allows for a reduction of effort on the part of a user while engaged in tasks or activities that are stationary or nearly stationary that lessens the strain on the bones, joints, and muscles normally used for standing while ensuring a proper alignment of the pelvis and spine.

An office-type chair includes a base, a height-adjustable pedestal extending upward from the base, a seat assembly including a rear seat part and a front seat part, and a linkage system connecting the pedestal to the seat assembly. The linkage system is adapted to pivot the seat assembly between a lowered position to serve as a task chair and an elevated position to serve as an elevated sitting support. A backrest arrangement may extend from the seat assembly. In the lowered position, the front and rear seat parts are both generally horizontally oriented. In the elevated position, the rear seat part may have a slight forward tilt and be positioned higher than in the lowered position, and the front seat part may extend at a downward angle relative to the rear seat part.

A saddle chair contains: a first seat and a second seat. The first seat includes a first connection sheet and an elongated orifice. The second seat includes a second connection sheet and a through orifice. A fixing member includes a slide slot having a slidable face, a receiving orifice, and a chute. A drive member is connected with a retainer via the receiving orifice, the elongated orifice, and the through orifice. The retainer includes a contacting face. Two screw bolts are screwed with the drive member via the retainer. A control bolt is screwed with a threaded orifice of the drive member and includes at least one recess on which at least one engagement block is fitted. Each engagement block has a screw and a forcing edge sliding between the slidable face and the chute, when the control bolt is rotated to move along the threaded orifice.
