A plinth attachment system for attachment to at least one track includes: a first plate having a first side configured for mounting to a longitudinally extending track, and a first mounting feature for mounting a first structure; and a second plate having a first side configured for mounting to the track, and a second mounting feature for mounting a second structure. When mounted on the track, at least one interlinking feature of the first side of the first plate and at least one interlinking feature of the first side of the second plate interlock at the track, and, the first mounting feature and second mounting feature are aligned at essentially equivalent longitudinal positions.

A rotary hanging chair comprises a cushion, a support frame and a base assembly. The cushion has two ends connected to an upper end of the support frame and is able to swing forwards and backwards with respect to the support frame. A bottom of the support frame is connected to the base assembly and is able to rotate within 360° with respect to the base assembly. The entire rotary hanging chair comprises three detachable parts, thus being simple and practical in structure, not only can swing forwards and backwards like a traditional hanging chair, but also can rotate within 360° to change the direction freely to meet the requirement for switching the view angle, and is small in size, easy to carry and capable of being used both indoors and outdoors.

To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layer 3 and upper and lower base units 4 and 5 arranged to sandwich the elastic support layer 3. The upper base unit 4 includes the rolling surface 42e bulging toward the lower base unit 5 thereabove via the elastic support layer 3, is rollable in a 360° direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layer 3 by the rolling surface.

The present invention is directed to a portable folding chair including a central assembly having an upper portion and a lower portion. The lower portion may be connectable to the upper portion so that the upper portion may swivel with respect to the lower portion. The portable folding chair may include leg members attached to the lower portion of the central assembly. Each of the leg members may be moveable between a folded position and a deployed position. The portable folding chair may further include seat members that may be attached to the upper portion of the central assembly. Each of the seat members may be moveable between a folded position and a deployed position.

A detachable seat includes an elongate support bar including a first bracket and a second bracket each positioned adjacent opposing ends of the elongate support bar, a seat support frame including a first support member and a second support member affixed to the first support member, a hinge pivotally connecting the first support member to the elongate support bar, a seat mounted on the second support member, the seat support frame and the seat pivoting around the elongate support bar upon pivotal movement of the first support member, and a retaining arm affixed to and extending from the elongate support bar adjacent the first bracket, the retaining arm including a plurality of alignment apertures formed along a length thereof.

The present disclosure relates to a mechanical extension apparatus for an extendable chair unit and a chair unit including such mechanical extension apparatus. The mechanical extension apparatus includes: a reclining apparatus that include multiple links attached to the seat, the backrest and the footrest of the extendable seat, and such reclining apparatus is configured to convert the extendable seat between a sitting position, a TV position, and a lying position. The mechanical extension apparatus also includes an actuator that is attached to the reclining apparatus, and the actuator is configured to electronically convert the extendable seat between the sitting position and the TV position; and the reclining apparatus is configured to convert the extendable seat between the TV position and the lying position by non-electric actuation.

A computer cockpit including a cockpit body, a driving module, a sensing module and a controlling module. The cockpit body includes a seat, a backrest and a display interface all movably disposed on the cockpit body. The display interface and the backrest are respectively located at two opposite sides of the seat. The driving module and the sensing module are disposed to the cockpit body, and the sensing module is configured to provide sensing data. The sensing data includes a seat pressure sensing value and a backrest pressure sensing value. The controlling module is electrically connected to the driving module and the sensing module, and configured to send an adjusting command according to the sensing data. The driving module is configured to receive the adjusting command to synchronously rotate the seat, the backrest and the display interface to a working angle and reduce a difference between the backrest pressure sensing value and the seat pressure sensing value.
