An apparatus includes at least one supernumerary artificial limb and a base structure configured to couple with a human body. The base structure includes a sensor that obtains a measurement regarding load of the human body. The proximal end of the supernumerary artificial limb is coupled to the base structure. The apparatus further includes a processor operatively coupled with the sensor and configured to receive the measurement from the sensor. The processor is also configured to generate a control signal to change at least one of a position of the supernumerary artificial limb and a torque exerted by the supernumerary artificial limb based on the measurement regarding the load.

A swing stool arm for use in a swing stool has a horizontal top flange, a horizontal bottom flange, a vertical end flange at a proximal end of the arm, a web extending down from the top flange and up from the bottom flange, and a vertical fillet at the proximal end of the arm. The vertical fillet joins the vertical end flange to the web. The vertical fillet has an open cavity so that the swing stool arm can be made from a cast molten aluminum alloy without forming shrinkage cavities.

A forward tilt assembly configured to tilt forward a seat of a chair. The forward tilt assembly includes a base, a seat plate, and a release mechanism. The seat plate is pivotally mounted to the base and includes two support brackets on the sides of the seat plate. Each support bracket includes a keyhole slot. The release mechanism is operable between locked and unlocked positions and includes a slidable lock pin mounted between the support brackets. The release mechanism includes two keyed collars, one disposed at each end of the lock pin. The collars are received in respective keyhole slots of the support brackets. When the release mechanism is in the unlocked position, the collars are unobstructed from moving within the keyhole slots, and the seat plate can pivot relative to the base, thereby tilting a rear of the chair seat.

The present invention relates to an item of seating furniture (2) having a seating frame (11) with a running gear and with at least one seating assembly (12), a table assembly (14), a footrest (13), a power storage system which supplies the seating furniture (2) with energy, a control unit, and a comfort, work, and/or entertainment device (15), wherein the control unit controls the one comfort, work, and/or entertainment device (15). In addition, the present invention relates to a seating furniture system (1) having at least one item of seating furniture (2).

A leaning chair can include a base defining a lower surface that rests on a floor, the base including a support surface; a shaft coupled to the base, the shaft defining a first end and a second end; a flexible mount coupling the first end of the shaft to the base, the shaft extending through the mount; a pivot pin located underneath the mount, the first end of the shaft resting on the pivot pin, and being configured to be housed inside the mount, the pivot pin being configured to pivot on the support surface; and a user support member coupled to the second end of the shaft.

A seating device includes a base and a seat post extending from the base. The seat post has a first end adjacent the base, a second end opposite the first end, and a longitudinal axis extending between the first end and the second end. The seating device further includes a seat supported by the seat post above the base and a first rocking assembly coupled to the base and the first end of the seat post. The first rocking assembly is operable to angularly displace the seat post relative to the base. The seating device further includes a second rocking assembly coupled to the seat and the second end of the seat post. The second rocking assembly is operable to angularly displace the seat relative to the seat post.
