A knock-down furniture component utilizes one or more tensioning mechanisms to draw interlocking framing members, including transversely-oriented interlocking framing members, together between opposed anchor points using directed linear tension between the anchor points and applied by a tensioning device.

A seating structure employing a thermoplastic flexor defining the flexibility and stiffness of a seatback is provided. The seating structure may comprise a seat portion for supporting a user, a seatback portion for supporting a user, a frame for supporting the seat portion and the seatback portion, one or more base portions extending at an angle from the seatback portion, and one or more thermoplastic flexors affixed to or within the seatback and base portions of the seating structure. The thermoplastic flexor has certain material characteristics which define and limit the deflection and a rebound of the seatback portion relative to the base portion when under load. The seating structure may further comprise one or more anchors securing the seatback portion, base portion, and thermoplastic flexor to the frame. The seat portion, seatback portion, and base portion may comprise a unibody or multipiece chair shell, and the thermoplastic flexor may be completely enveloped within the shell, or partially disposed behind the shell in a nested mechanical relationship.

An apparatus for sitting, including: a keystone assembly which connects various parts of the apparatus; a back that provides support for at least a person's back or shoulders; a floating lumbar support, which provides support for a person's lower back, attached to the keystone assembly; a seat that can adjust between a forward tilted and reclined position; a plurality of rollers, disposed on the keystone assembly, on which the seat rests; a central column, attached to the keystone assembly, on which the seat can spin; and a lower torsion spring connected to the seat and disposed on the keystone assembly allowing controlled movement of the seat.

A car seat includes an air outlet located in a seat upper portion (a portion provided above a seat cushion and including a seat back and a headrest) to let out air therethrough; an air inlet located in the seat upper portion to draw in air therethrough; at least one fan configured to produce a current of air flowing from the air outlet toward the air inlet at a front side of the seat upper portion; and a scenting device configured to scent air to be forced out through the air outlet. The air outlet and the air inlet are located in such positions that at least part of the headrest is positioned between the air outlet and the air inlet in a direction from the air outlet toward the air inlet as viewed from a front side.

A surgeon support system comprising a base having a foot platform with an appropriate angle adapted to support a user's feet. The base surface may be lifted using a jack pedal and the height is adjusted by a base handle. A knee pad is supported by a knee support bar which is attached to the base. The knee pad is pivotally connected to a seat pad and a chest pad support bar. The seat pad is supported by a seat pad height-adjusting strut and the height is adjustable by a seat pad height-adjusting handle. The chest pad support bar supports a chest pad for forward and backward movement of the user. The angle position of the chest pad is adjusted and released by an angle-adjusting knob on a chest pad angle-adjusting bar. The surgeon support system stabilizes a user close to a workspace for extended periods of time.

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.

A toting apparatus can include a bucket, a combination lid and seat cushion, and a harness for carrying the apparatus while the lid covers the top opening of the bucket and the cushion is in the inflated or deflated configuration. The cushion can be formed by a drop-stitch type bladder inflatable using a common hand-operated bicycle pump. The harness can include a belt that wraps around the bucket and a pair or diametrically spaced-apart straps that adjustably and snuggly attach to a central handle structure atop the lid. Various corresponding patches of hook-and-vane style fabric fasteners allow for releasable affixation of various components of the apparatus. Thus the harness can be made of durable flexible fabric.

A connector comprises a body, a first connection part, and a second connection part. The first connection part and the second connection part are respectively disposed at two adjacent side surfaces of the body of the connector. The first connection part and a horizontal rod are engaged, the second connection part and a vertical rod are engaged, to form a detachable connection between the horizontal rod and the vertical rod with the connector. Without dealing with an over edging operation of a boundary and a corner of the frame, the rattan pieces are directly connected to the horizontal rod or the vertical rod, to perform the weaving of the chair back, which greatly reduces the difficulty of weaving. The first side surface is a step shaped surface, which reduces the difficulty of the engaged connection between the first connection part and the horizontal rod. The connector is a one-piece structure.

A seat skate assembly is configured to be secured to a fitting of a seat assembly. The seat skate assembly includes a pin-retaining guide including a plurality of pin cavities configured to receive and retain one or more pins of the fitting, one or more wheel couplers, and one or more wheel members rotatably coupled to the wheel coupler(s). The wheel member(s) allow the seat assembly to be moved.

An improved virtual reality system comprises a chair 110 integrated with a pedestal 120, which contains a motion platform 150 and base 160. The chair 110 can be rotated continuously in the yaw axis by a stepper motor 230 and substantially in the pitch axis by an additional stepper motor 240 in coordination with the content of the VR display as directed by a chair controller located on the motion platform 150.
