A compact recliner mechanism for use in theater seating units is provided that allows the seat to move linearly as the seating unit moves from the closed position to the reclined position. The mechanism has a back bracket coupled to the seat plate and base plate with a linkage that moves a projected point representing the top of the back of the seating unit downwardly in vertical plane as the seating unit moves from the closed position to the reclined position. In other aspects, the seating unit has an armrest linkage coupled between the seat plate and the back that maintains an armrest lever at a horizontal orientation. Additionally, in some aspects, the base plate of the seating unit may have an adjustment feature that limits recline of the seating unit, to accommodate theater seating with different riser dimensions, and/or legs with an adjustment feature to level the seating unit on existing theater floors.

A seating furniture includes a seat device and a backrest device connected via at least one first rotatable coupling in respective coupling portions (P) of the backrest device and at rear portion (B) of the seat device. A base supports the seat device and the backrest device. The backrest device comprises a portion extending in a direction towards the base and past the first rotatable coupling, and the portion is rotatably coupled to and supported on the base via at least one respective link arm. The seat device is rotatably coupled to and supported on the base via a second rotatable coupling attached closer to front end (F) of the seat device than the first rotatable coupling. A lockable control device controls the movements between the backrest device and the seat device. The construction is well-balanced, and low forces are required to adjust the chair in all positions.

An adjustable rotary rocking chair having a chair frame assembly A, an adjustment mechanism B, and a support tube assembly C, wherein the adjustment mechanism B is detachably connected with the chair frame assembly A and is connected with the support tube assembly C in an insertion manner. The adjustable rotary rocking chair can swing and rotate, has higher flexibility and adaptability due to the fact that the height of the rocking chair and the height of the support tubes can be automatically adjusted by users, is portable through a folding design, and can be used indoors and outdoors.

A chair according to the present invention has a reference position P located midway in a front-back direction in a movable range of a seat 2. The chair includes a return force generation mechanism 4 configured to generate a return force in a direction to return the seat 2 moved from the reference position P at least in the front-back direction to the reference position P. The return force generation mechanism 4 includes an elastic member 40 configured to increase the return force in the direction to return the seat to the reference position P as the amount of movement of the seat from the reference position P increases.

A tilt-swivel chair employing a bearing base assembly in communication with connection plate or seat plate of the chair is provided. The tilting mechanism in forward and backward direction is provided by the spring which has a pushing and pulling action and the swiveling action is done along the side axis of the bearing base assembly, and the side axis is a cylindrical shape section with a bushing cap onto which a lever base is equipped and is connected to the connection plate or seat plate. The balance ball feeling is provided with the spring action. A cam and lever mechanism is provided at the base of the side axis in corporation with the base section of the assembly. The cam and lever mechanism provides a smooth swiveling action to the seat and to lock and shut down and take a break.
