A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane has a first region with a first stiffness and a second region with a second stiffness. The second stiffness is greater than the first stiffness. The membrane may form a part of a seat or a backrest.

A power lift-recliner chair has a base, seat and backrest sections and actuator for moving the seat and backrest sections. The seat is pivotally mounted with respect to the base section and the backrest section is pivotally mounted with respect to the seat section. A guide is associated with one of the base and the seat sections and at least one follower is associated with the other of the base and the seat sections. The guide is arcuate for relative pivoting with respect to the base about a pivot axis located at the center of curvature of the guide. The base section includes a pair of side panels on lateral sides of the chair. The seat includes a pair of side members, adjacent the side panels, which carry the guide or follower associated with the seat section.

Chairs, seating systems, chair sub-assemblies and sub-systems, and associated methods of assembly and use. Aspects relate to chairs and methods of assembling chairs including chair controls of a relatively compact and effective design with desirable synchronous raising and tilting motions. Aspects also relate to tilt lock assemblies for achieving secure and effective tilt securement. Additional aspects relate to forward and rearward adjustment, or extension and retraction, of a seating assembly of the chair.

A chair has a supporting frame 1, a seat portion 101, a back portion 201 that has an upper end, a lower end, and is pivotally mounted relative to the supporting frame at a position above its lower end, and a recline mechanism 601. The recline mechanism 601 lifts the seat portion 101 upon a reclining action of the back portion 201, and has an operative connection 603, 611 between the seat portion and the supporting frame and a drag link 602 pivotally connected to the seat portion 101 and pivotally connected to the back portion 201 at a position below the pivotal mounting of the back portion relative to the supporting frame. As the back portion 201 of the chair is reclined, the lower end of the back portion 201 moves forward and the drag link 602 pulls the seat portion 101 upward relative to the supporting frame 1.

A seating/reclining furniture comprising a seat part, a backrest part, and a cantilever support structure. A foot support device is provided which comprises a support frame and a first and a second foot support portion, and the first foot support portion is pivotally mounted on the support frame and can be adjusted between a storage position and a working position. The second foot support portion can be adjusted linearly relative to the first foot support portion between a retracted position and an extended position. The foot support device comprises a working device which causes the first foot support portion to be pivoted relative to the support frame by means of a first fitting and the second foot support portion to be moved relative to the first foot support portion by means of a second fitting independently of a change of the relative position of the backrest and the seat part.

The invention relates to a chair, in particular a conference or visitor chair, which allows a coupled movement of a seat (3) and a backrest. The seat in this case is mounted in sliding bearings (4) comprising oblique guide surfaces (6) and is displaced and raised in the sliding bearings through a mounting end (5) of the backrest. According to the invention, two separate backrest bars (11) are provided, which are connected to the mounting ends (5), wherein the backrest bars can be moved independently of each other. In this way, different seat positions can be realized. Besides an upright standard position, an inclined high position, and an asymmetrical position, in which a one-sided load of a backrest bar (11) can be realized with a corresponding displacement and rotation of the seat (3).

A chair comprising a base structure comprising a support, a seat connected to the support via a synchronization mechanism and movable with respect to the base structure between a lowered position and a raised position, and a backrest connected to the synchronization mechanism and movable between an upright position, corresponding to the lowered position of the seat, and a backward-inclined position corresponding to the raised position of the seat, wherein the synchronization mechanism comprises two loop-shaped elastic elements spaced apart in a transverse direction and each comprising a lower portion fixed to a rigid support, an upper portion fixed to the seat, a front elastic portion and an essentially C-shaped rear elastic portion that connect the upper portion to the lower portion, wherein the backrest is fixed to the rear elastic portions of the loop-shaped elastic elements.

A folding chair with multiple modes may include a first frame and a second frame rotatably connected by a joint assembly, a first support arranged in the first frame and a second support arranged in the second frame and six legs. The six legs may include a first pair of legs rotatably attached to the second frame, a second pair of legs rotatably attached to the first frame (e.g., via another joint assembly), and a third pair of legs rotatably attached to the second frame. The folding chair may further include a pair of armrests rotatably attached to the joint assembly. The multiple modes of the folding chair may include a first mode wherein the folding chair is configured as a dining chair, a second mode wherein the folding chair is configured as a lounging chair and a third mode wherein the folding chair is configured for compact storage.

The invention provides an article of adjustable furniture (10), preferably an adjustable chair or bed, comprising a floor standing base section (16), adjustable seat (18), backrest (20) and headrest (130) sections and actuator means (100) for moving the backrest and headrest sections. The seat section is movably mounted with respect to the base section. The backrest is movably mounted with respect to the seat section and the headrest is movably mounted with respect to the backrest section. The actuator means includes a single actuator (102) for co-ordinated movement of the adjustable backrest and headrest sections for selectively altering the configuration of the article of furniture. The actuator has a first range of movement for moving the headrest with respect to the backrest, and a second range of movement for moving the backrest with respect to the seat section to provide a recliner function. The invention also provides an article of adjustable furniture comprising a backrest (20) and an adjustable headrest (130) pivotally mounted with respect to the backrest, actuator means (100) for moving the headrest between raised and lowered positions, and guide means arranged between the headrest and the backrest for rotating the headrest with respect to the backrest as it moves between said raised and lowered positions. The guide means includes first (138) and second (140) guides, each associated with one of the backrest and the headrest and having at least one follower (142, 144) associated with the other of the backrest and headrest. The first and second guides are inclined with respect to each other such that a turning moment is generated on the headrest when the headrest is raised or lowered.
