An assembly chair includes a seat frame, a back frame and two armrests. The seat frame is rotatably connected to the back frame. The seat frame is respectively clamped with the two armrests. The two armrests are fixedly connected to the back frame via a hand bolt. The assembly chair is simple to assemble, and may be assembled by a manpower without the help of an assembly tool; and the consumption time is short, and the assembly efficiency is improved obviously.

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 chair is realized which takes specific measures to suppress movement of a seat in a front-rear direction when the seat swings in the front-rear and the left-right directions with respect to a support base.

For the purpose, the chair wherein a seat 5 swings in the front-rear and left-right directions with respect to a support base 2, the chair is configured such that swinging of the seat 5 in front-rear direction with respect to the support base 2 is capable of being suppressed at one or a plurality of predetermined positions, or arbitrary position via operation of operation member 152.

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.

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 seat connection mechanism and a seat employing that mechanism where the mechanism is constructed from a combination of metal, for example extruded or cast, plastic bushings and plastic covers to create a fully enclosed tilt mechanism for seats which is reliable, easy to maintain and allows for easy removal of seats for repair thereof so long as the person removing the seat knows the removal process. Thus vandalism is inhibited and a relatively economical bracket and seat is provided with substantial durability and reliability.
