A system for seated support. A seat rest may be configured to support the posterior of a user, a leg rest may be configured to support a leg portion of a user, and a combined translate-and-cant reposition carriage may be configured to simultaneously translate and cant the position of the leg rest in relation to the position of the seat rest. The seat rest, leg rest, and combined translate-and-cant reposition carriage may comprise an equipoise balancer for a user. The equipoise balancer may be free-floating, lockable, partially lockable, seat-rest driven, or leg rest driven in various embodiments.

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.

A motion base (100) includes: a first installation base (1a); a first movable base (2a) on which a placement subject is to be placed and that is disposed on the first installation base (1a); at least two first actuators (3a) each of which is extendable and contractible; first connecting portions (1a) connecting the first actuators (3a) to the first movable base (2a); second connecting portions (4b) connecting the first actuators (3a) to the first installation base (1a); and a spherical surface body (5) that has a spherical surface-shaped portion (15), is disposed on the first installation base (1a), and supports the first movable base (2a) such that an attitude of the first movable base (2a) can be changed relative to the first installation base (1a) by sliding the spherical surface-shaped portion (15).

A unitary dining unit combining table functions and seating, which dining unit solves the above stated problems, is disclosed. The novel dining unit may be oblong, with opposed convex surfaces, to enable occupants to easily view one another, and to assist in fitting the table or desk efficiently within a square or rectangular room of a building. The unitary dining unit integrates a work surface, e.g., a table or desk surface, with seating. The integrated seating has support arms connecting the seating to the table portion, and maintaining all portions of each seat above the floor, thereby leaving space for and facilitating floor cleaning in the area of the furniture. A perimetric wall serves as an aesthetic skirt concealing seat anchorage elements and other utilitarian components from external view.

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).

A vehicle seat hinge assembly includes a first pivoting member that defines a first axis and is coupled to a first bracket disposed on a vehicle floor. The hinge assembly also includes a second pivoting member that defines a second axis and is disposed on a seat. The first pivoting member is pivotable about the first axis between at least first and second positions. The second pivoting member is pivotable about the second axis between at least fixed and released positions.

A tilting mechanism (1) for chairs includes a support frame (2), a structure (4) rotationally coupled to the support frame. An elastic system (80) is interposed between the support frame and the structure to counteract a reaction to the tilting of the structure from an at-rest position to a tilted position. An adjustment system (20) is capable of varying the reaction to the tilting. The elastic system (80) includes at least one elastic element (12) and a first and a second stop element (81, 82) fastened at respective longitudinal end portions of the elastic element, respectively. In the at-rest position, the first and second stop elements are in contact with each other, and the elastic element (12) is in a deformed configuration and generates a residual elastic force that is at least partially released on the first and second stop elements.

An aircraft seat device includes at least one seat bottom unit, a mounting unit, and at least one carrier element. The at least one seat bottom unit at least partly implements a seat surface. The at least one carrier element couples the seat bottom unit with the mounting unit and transfers force from the seat bottom unit to the mounting unit.

To provide a chair in which the seated person can perceive a comfortable sitting feeling even if sitting for a long time, and furthermore a high work efficiency can stably be maintained, a chair according to the present invention includes a support mechanism 2 interposed between a leg 1 and a seat 3, wherein the support mechanism 2 includes: a seat inclining mechanism Q as a seat inclining function configured to downwardly incline a tip side in an operation direction of the seat 3 when the seat 3 operates from a predetermined reference position (S), and further includes: a return-force generation mechanism configured to generate, in accordance with an amount of movement, a return force in a direction of returning the seat 3 having moved from a reference position (S) in a front-rear or left-right direction, to the reference position (S).
