The reversible chair comprises two articulated portions (1, 2) with respect to a support (3), both articulated portions (1, 2) being able to be placed in a first position, wherein the articulated portion (1, 2) is in a substantially vertical position, and in a second position, wherein the articulated portion (1, 2) is in a substantially horizontal position, the chair further comprising two stop plates (4, 5), each of which is joined in rotation to one of the two articulated portions (1, 2), said stop plates (4, 5) being separated from each other when the two articulated portions (1, 2) are in the first position and in contact with each other when one of the articulated portions (1, 2) is in the second position. It provides a reversible chair that can be oriented in two different orientations and that is as simple and cheap as possible.

Methods and apparatuses are disclosed to help the elderly or physically impaired individual standing up from a chair, a bench, a wheel chair, a toilet seat, a commode, a rollator seat, a walker seat, or a car seat. The disclosed apparatus to generate lifting thrust for individual to stand up from a chair has a base, a slidable seat pivoted mounted on the base and a lifting spring to reserve the energy on sitting down and release the saved energy on standing up.

An adjustable seat includes a carrier, a seat body, a first linking rod, a second linking rod, a sliding mechanism, and an adjustment block. The seat body is arranged on the carrier and includes a seat surface switchable between a first direction and a second direction. The first linking rod is hinged to the seat body and the carrier. The second linking rod is hinged to the seat body and the carrier. The sliding mechanism includes a slide rail and a slide block slidably engaged with the slide rail. The slide block is hinged to the seat body. The slide rail is hinged to the first linking rod and the second linking rod. The adjustment block is slidably coupled to the slide rail or the seat body for switching the seat surface between the first orientation and the second orientation.

A wall-proximity reclining seating unit includes: a frame having a back member and a pair of arms, the back member being fixed relative to and extending between the arms; a backrest; a seat; a footrest; a reclining mechanism connected between the frame, backrest, seat, and footrest comprising a series of pivotally interconnected links that move the seating unit between: (a) an upright position, in which the footrest is retracted below a forward portion of the seat and faces generally downwardly and defines an angle of between about 20 and 40 degrees with the underlying surface, (b) a TV position, in which the footrest is extended in front of the seat and is generally horizontally disposed, and the seat and backrest are moved forwardly relative to the frame between about 2.5 and 4 inches; and (c) a fully reclined position, in which the backrest is disposed at an angle shallower than the first backrest angle, the footrest remains extended in front of the seat, and the seat is moved forward of its position in the TV position between about 4 and 7 inches. A power actuator coupled to the reclining mechanism drives the backrest, seat and footrest between the upright, TV and fully reclined positions.

A chair frame mechanism and a chair having the same are provided. The chair frame mechanism includes a movable component, a chair bracket, a leg component, a back component and a sequence component. The movable component is connected with the chair bracket. The leg component and the back component are pivotally connected with the chair bracket, respectively, and the back component is connected with the movable component. The sequence component is connected with the movable component and the chair bracket, respectively, and connected with the leg component and the back component by transmission, respectively. The sequence component is capable of controlling the chair bracket to move relative to the movable component along a preset trajectory, and orderly controlling the leg component and the back component to extend or fold relative to the chair bracket.

A seating furniture chassis comprises a base body, first and second side parts, a back part, a plurality of electrically conductive cables fastened to the base body, first and second fasteners arranged on the base body, wherein the back part is releasably fastenable to the first fastener and the first and second side parts are respectively releasably fastenable at two opposite sides of the base body to the second fastener, and a plurality of individual connectors and a central connector, wherein the electrically conductive cables each connect one of the individual connectors to the central connector.

A folding seat, having a supporting structure, to be fixed to a wall, for a sitting surface which can be tilted from a vertical inactive position to a horizontal active position by way of a tilting mechanism. The seat includes a group of elements used for adjusting a tilting force.

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.

There is described a seat module for use in furniture for sitting, the seat module comprising a backrest (1) and a seat (2) and a coupling element (3), the backrest (1) being adapted to run along rear grooves (7) arranged in respective sides of the coupling element at its rear edge, a rear portion of the seat (2) is connected to the backrest (1) and a front portion of the seat (2) is adapted to run along front grooves (9) arranged in respective sides of the coupling element in its leading edge. The seat module further comprises a tilting mechanism (15-19) connecting the coupling element with a support member or base (4).

The invention relates to a seat device (1) comprising an underframe (2) and a seat (3) connected to the underframe (2) in such a way as to pivot about a seat axis (A1), there being provided means for elastically biasing the seat (3) in anti-clockwise rotation. The seat device (1) further comprises a lumbar part (42); rotationally secured to the seat (3), and a saddle (5) for supporting the top of the thighs of the user, the saddle (5) being connected to the front region of the seat (3).
