摘要： 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.

摘要： 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.

摘要： A chair, in particular an office chair, has a seat inclination mechanism. A transverse strut of the seat inclination mechanism forms a spring device and this spring device has at least one torsion element. The seat inclination mechanism further has a basic support on which a backrest support and a seat element support are articulated. The transverse strut of the seat inclination mechanism forms a spring device. The transverse strut extends in the chair transverse direction and wherein the spring device has at least one torsion element, in particular a torsion bar spring. The torsion element, together with the basic support and/or the backrest support and/or the seat element support, is formed integrally, in particular in one piece, from plastic.

摘要： A vibrotactile support with suppressed distortion and destructive interference having a rigid frame within which is tensioned a high-density material panel in a supportive configuration. A low-durometer, high specific gravity material user interface pad is placed on the high-density panel on the user-supporting side and a plurality of acoustic drivers are attached to the opposing side of the high-density material panel to transmit vibrations through the high-density material panel, the pad, and the user's skin. The acoustic drivers are supplied from an amplifier which is supplied from an electronic audio source. The amplifier may also drive a set of headphones for the user. The audio source may be from any known electronic audio source, including audio-visual presentations. Various shapes and configurations of the vibrotactile support are possible. For non-limiting examples, the vibrotactile support may be configured as a lounge chair, upright chair, baby cradle, or flat bed.

摘要： The present disclosure discloses a chair and a chair base. The chair base comprises a connection pipe, four support legs, and two C-shaped swinging rods. The four support legs are respectively disposed along four directions. The two support legs disposed in a left-to-right direction are fixedly connected to the connection pipe, and lower sides of middle portions of the two support legs are respectively disposed with a hinge piece. The two support legs disposed in a front-to-rear direction are rotatably connected to the connection pipe and comprise sliding sleeves. Two ends of the two C-shaped swinging rods are respectively rotatably connected to the hinge pieces of the two support legs disposed in the left-to-right direction. Middle portions of the two C-shaped swinging rods are respectively connected to the sliding sleeves of the two support legs disposed along the front-to-rear direction through link rods.
