The present application relates to a chair which adapts to dynamic body postures of a user. The posture adaptive work chair includes a seat sub-assembly having a front edge and a seat base sub-assembly; a pair of spine members cantilevered from the font edge of the seat sub-assembly; a back sub-assembly supported by the pair of spine members, and configured to flex in multiple axes based on a direction of load applied by a user; and a tilt limit lever movably coupled to the seat base sub-assembly and configured to enable tilting of the back-sub assembly to a plurality of tilt positions.

A patient support apparatus includes a frame, a stationary member mounted relative to the frame, a movable member having a pivot member rotatably mounting the movable member about the stationary member, and a fastener securing the pivot member to the stationary member. The patient support apparatus also includes a joint between the pivot member and the stationary member, which is configured to apply a tension force on the fastener.

A frame for a simulator includes first and second guides and subframes for a seat and for a steering wheel which are slidable in the frame along the guides. The subframes include fixation devices. Each fixation device includes a fixation member which extends on either side of the respective guide and which has a recess through which the guide protrudes. The fixation member is pivotable about an axis oriented perpendicularly of the guide between a release position, in which mutually opposite edges of the recess lie at a distance from the guide, and a fixation position in which the edges engage on mutually opposite sides of the guide. A subframe slidable along a guide for use in such a frame. A fixation device for use in such a frame.

A tiltable stool includes a seat which is connected to a base by an elongated body structure. The base has an upper base element and a lower base element. The upper base element is resiliently deformable. The resiliently deformable upper base element allows the stool to pivot in any direction. The lower base element is a rotationally symmetrical outwardly convex and inwardly concave body. The upper base element may include one or more annular grooves.

The embodiments relate to a geometric under structure, central and outer hub for a GFN plastic chair base. The geometric shape and dimensions are critical components to the overall strength of the chair base hub and arms when either vertical or rotational forces are applied at the central hub. The central hub is of sufficient thickness to maintain dimensional stability when the forces are applied. The overall geometry and material composition enable the hub area to be constructed with minimal plastic wall thickness while optimizing the physical strength of the article and facilitating high production rate.

A reclining chair or the like provides a set of base-mounted extendable arms that move forward as the chair reclines, and the leg rest extends to brace the chair against forward tipping, for example, if weight is applied to the leg rest without the counterbalance of an occupant. When the leg rest retracts, the arms pull back to reduce tripping hazard.

The present disclosure provides a garden chair including: a garden chair body, including a first chair leg, a second chair leg, and a carrying frame; wherein the first chair leg is spaced apart relative to the second chair leg; an end of the carrying frame is arranged on the first chair leg, and the other end of the carrying frame is arranged on the second chair leg; and a cushion, removably arranged on the carrying frame. In the garden chair provided by the present disclosure, the cushion is removably arranged in the carrying frame, such that the cushion is easy to clean and replace, and the disassembled cushion can be applied to a variety of functional kneeling cushion and seat upholstery mobile cushion.

The invention disclosure relates to the technical field of supporting chair legs, in particular to a three-leg assembly and disassembly structure for supporting chair legs in a star shape. The foot is movably connected to the end of the mounting part away from the central support. By providing a mounting groove and a connecting section, the connecting section of the supporting foot is vertically inserted into the mounting groove, so that the cylinder axis part is clamped into the limiting groove and then rotated the support foot upward ninety degrees, until the abutment section abuts against the limiting groove, the support foot can be installed.

A body support structure includes a base, a seat and a backrest, with the backrest connected to the base with a torsion leaf spring. The torsion leaf spring may be configured with a plurality of fingers, and/or one or more flex regions. One or more struts may be connected between the seat or backrest and the base. In another aspect, the seat and/or backrest may be supported with one or more links that provide a counter-intuitive motion. In another aspect, a link may be coupled to a support with a flexible blade.

The patent application discloses a highly stable seat chassis. The highly stable seat chassis may comprise a chair leg main body having a plurality of outstretching arms extending in a circumferential direction. The outstretching arms may comprise at least one first fixed arm, and a disassembly system. The disassembly system may be provided on the first fixed arm. The disassembly system comprises a dismounting arm and an insert plate fixedly connected to the dismounting arm. The first fixed arm is provided with a slot. The insert plate and the slot are provided with matching connecting holes.
