摘要： In the chair, a space between swinging surfaces facing each other can be appropriately unseen. The chair includes swinging surfaces (rolling surfaces) (312a) and (322a) facing each other and has a configuration in which the swinging surfaces (312a) and (322a) swings with respect to each other in directions of 360 degrees including front-rear and left-right directions. In such a chair, an elastic member (33) is arranged to be positioned between the swinging surfaces (312a) and (322a) at least in the vicinity of outer peripheral edges (312z) and (322z), and a stretchable sheet material (60) is provided between the outer peripheral edges (312z) and (322z) to conceal a gap between the swinging surfaces (312a) and (322a) facing each other, the gap including the elastic member (33).

摘要： A swingable chair chassis comprises a rocker seat including a chamber defined between a bottom wall and a peripheral wall. The bottom wall includes a slot extending in a front/rear direction. A lid is securely mounted to a bottom of the seat and the rocker seat. A supporting seat is disposed in the chamber of the rocker seat. The supporting seat includes a central portion having an insertion hole coupled with chair post. The supporting seat includes an arcuate supporting face formed on an upper side thereof and abutting against a lower face of the lid. A plurality of elastic elements is disposed between the bottom wall of the rocker seat and the supporting seat and provides movement elasticity when the rocker seat swings forward or rearward relative to the supporting seat. The supporting face abuts against the lower face of the lid during swinging movement of the rocker seat.

摘要： A seating arrangement includes a seat assembly slidably movable between a forward most position and a rearward most position and that includes a seat support structure configured to support a seated user thereon, and at least one elongated slide bearing attached to the seat support structure and including a bearing surface and at least one stop member, wherein the bearing surface and the at least one stop member are a single, integral piece. The seating arrangement further includes at least one slide support member that slidably supports the slide bearing thereon between the forward most position and the rearward most position, wherein the at least one stop member is configured to prevent the seat assembly from being moved beyond at least one of the forward most position and the rearward most position.

摘要： A chair having an articulating backrest that deforms when reclined to support an occupant's head or shoulders. A backrest assembly includes a mesh insert secured to a frame, which includes an upper frame section and a lower frame section interconnected by a pair of articulated joints. A push arm pivotally connects to the chair's seat assembly and to the backrest's upper frame section. As the chair reclines, the push arm restricts the angular movement of the upper frame section relative to a floor. The lower frame section moves forward relative to the upper frame section. Consequently, an angle formed between the lower frame section and the upper frame section decreases during recline, thereby supporting the chair occupant's head or shoulders. Optionally, a tensioning member may connect the mesh insert to the push arm to offset any loss of tension caused by the deformation of the frame during reclined.

摘要： A reclinable office chair includes a reclination adjustment unit disposed at the bottom of the office chair. The reclination adjustment unit balances itself on the floor properly, resiliently and steadily. The office chair tilted in a forward-backward direction and/or a left-right direction displays directional stability relative to the floor in a manner not to lose the directional stability even when a sitter tilts in any direction, thereby allowing the office chair to provide a comfortable seat for the sitter to sit on, regardless of whether the office chair is upright or tilted in any direction.

摘要： A mobile task chair with a mobile base structure, a control mechanism, a seat bottom, and a seat back. A physical setting control mechanism is adjustable to control a physical setting of the mobile task chair, and a visual indicator provides a visual indication, such as an illuminated visual indication, of the physical setting of the mobile task chair as adjusted by the physical setting control mechanism. The physical setting control mechanism can be pivoting resistance adjustment mechanism, and the visual indicator can indicate a selected pivoting resistance based on a resistance sensed by a resistance sensor. Multiple physical setting control mechanisms and a corresponding multiplicity of separate visual indicators can be provided. The visual indicator can be selectively induced as by touch and can be effective for a given time period. Recommended settings can be provided and automatically or selectively induced.

摘要： Seating assemblies and methods are disclosed. A seating assembly can comprise a seat, a back support, and a frame component. The frame component can extend from a bottom portion, positioned near an underside of the seat, to a top portion, configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion to a right edge portion and can include a spring member at or near each of the left and right edge portions. The spring member can include at least one undulation or are providing integrated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism, engaged with the frame component, including one or more leaf springs and a spring contact assembly. The spring contact assembly can be positioned on a top side of the one or more leaf springs.
