The frame assembly is configured to support the seat subassembly relative to the floor in a lowered position thereof, in a raised position thereof, in intermediate seat positions therebetween, and in Trendelenburg positions.

The present disclosure provides a chair with a rotatable armrest, comprising a seat body, which is provided with an armrest, a backrest and a rotating member; wherein the backrest is arranged at a position on one end portion of the seat body, the rotating member is fixed on one end of the seat body near the backrest, the armrest is rotatablely connected with the seat body through the rotating member, and the armrest is capable of rotating roughly horizontally with respect to the seat body. According to the present disclosure, a user can leave the chair from one side of the seat body, moreover, when the user is leaving the chair, the rotated armrest can still provide help for the user.

A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane includes different regions with different stiffness. The membrane may form a part of a seat or a backrest.

Armrest (10) comprising a base (19) and an arm (13) that can be moved by a mount (17) between at least one use position and a non-use position, wherein the arm (13) is movable by the mount (17) axially of a pivot axis (a) between a proximal and a distal position, and is pivotable about the pivot axis (a) between a primary and a secondary position, wherein the armrest (10) has an actuator (30) comprising a motor drive having a drive part (29) that is movable between a first and a second position in order to displace the arm (13) in a first direction (y.sub.1) between the non-use position and the use position, at least in part, wherein the actuator (30) has at least one spring (21) that can be tensioned upon movement of the drive part (29) or an additional drive part (29) of the actuator (30), wherein the arm (13) can be moved axially, in a second direction (y.sub.2) by the spring (21), which second direction is directed opposite the first direction (y.sub.1).

A foldable multifunction chair including a base for contacting a support surface; a user body support having a support front surface for contacting a user body, the user body support being adjustably pivotably mounted to the base along a transversal axis; a selectively adjustable chair deployment mechanism cooperatively coupled to the base and the user body support, the chair deployment mechanism being configured for selectively adjusting the user body support to a desired angle relative to the base; and a locking mechanism configured for angularly locking the user body support to the desired angle relative to the base. The chair may be used, e.g., as a backrest with an accessory support positioned in front thereof for work, or as a seated workstation wherein the accessory support is positioned adjacent a rear surface of the user body support in a deployed position, and the collapsible seat in a deployed position.

A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane includes different regions with different stiffness. The membrane may form a part of a seat or a backrest.

An elevation hinge where one of the parts moves in connection to a guiding means on another part, and wherein a supporting effect is achieved on an elevation of said moving part. The elevation hinge comprises a first part including at least one guiding means, and a second part including at least one connection element for guiding the second part along the at least one guiding means. The guiding means includes a second portion adapted for guiding the connection element to and from a first portion. Guidance is performed in a linear manner or in a rotational and linear manner, in relation to the first part. A spring is fixed between a connection element and an anchor pin on the first part.
