Recliner

Recliner chairs provide for lowering the back-supporting surface thereof from a somewhat vertical position to a somewhat horizontal position, allowing the user to lie rather than sit. Recliner chairs provide the ability for the user to vary the angle of a seat assembly, typically between a generally upright sitting position and a reclining position. The motive power for moving the seat assembly from one position to another may be provided by an electric motor or by the user. Generally, such chairs provide a foot rest to support the legs of the user while the back of the chair is reclined. A standard recliner chair has a generally fixed and normally horizontal main body on which a head and foot part is movable between a horizontal position level with the main body and a raised or lowered position extending at an angle thereto. The movable part is typically hinged and/or slidable on the frame of the piece of furniture and is raised or lowered by an operating bar extending along a pivot axis fixed in the frame and having arms engaging the movable part and at least one crank arm engaged by an actuator normally housed in the main part. Rotary recliner mechanisms usually include an outer rotary member having a plurality of inwardly-projecting gear teeth and an inner rotary member having a plurality of outwardly-extending gear teeth. The gear teeth of the inner rotary member move circumferentially about the gear teeth of the outer rotary member to selectively rotate the inner rotary member relative to the outer rotary member. Recliner chairs come in a variety of shapes and sizes. Some chairs have a rocking mechanism, some chairs have extendible footrests, while other chairs have seats and seat backs that move from a normal upright position to a reclined forward position. While a given recliner chair can possess any one or all of these features. Most recliners are designed to include a foldable structure and an inclination-adjustable backrest. Some of the currently available recliners also include a backrest that can be steplessly adjusted to different inclination, and frames pivotally connected to each other via specially designed angular or bent joints.
