A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A reclining seatback support device which mainly includes at least one seatback support and a seatback body is revealed. The seatback body and an upper end of the seatback support are provided with pivot bracket portions pivotally connected to each other while a lower part of the seatback body and the seatback support are connected by a swing arm. When a user is sitting and lying down on the back, the seatback body is rotated around the pivot axis where the seatback body is pivotally connected to the upper end of the seatback support and then reclined at a certain angle. By elastic segments of the seatback body and the swing arm between the lower part of the seatback body and the seatback support for pulling and limiting the seatback body, the user can lean on the seatback body comfortably and safely.

A chair with a transom, a seat support, a back portion, and a combined rock and recline mechanism. The combined rock and recline mechanism has front and rear rocking arrangements configured to enable the seat support and back portion to together rock generally forward and rearward from a neutral position relative to the transom, and a recline arrangement that is configured such that the seat support is in a first at-rest position relative to the back portion when the back portion is in an upright position, and such that reclining the back portion rearwardly from the upright position toward a reclined position moves the seat support upward and rearward from the first at-rest position.

A seating arrangement includes a base, a lower shell including a first portion coupled to the base and comprising a substantially horizontal portion, a curved transition portion and a backrest portion, a pair of laterally spaced front links extending upwardly from a forward portion of the first portion, a rear link extending upwardly from a rearward portion of the first portion of the lower shell and forwardly of the transition region of the lower shell, and an upper shell comprising a seating portion coupled to the pair of front links and to the rear link, a curved transition portion spaced apart from the curved transition portion of the lower shell and defining an open lateral pass through therebetween, and a backrest portion connected to the backrest portion of the lower shell.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A reclining chair having a seat, backrest and armrest is provided. The armrest has a first portion associated with the seat and a second portion associated with the backrest. The first and second armrest portions are slidable relative to each other between a first position associated with a raised backrest and a second position associated with a reclined configuration. The armrest also has a locking mechanism of the sliding between the first and second armrest portions, and the locking mechanism has first and second locking seats and a locking element configured to couple alternatively to the first-or to the second locking seat. A coupling of the locking element to the first locking seat is associated with the first position and a coupling of the locking element to the second locking seat is associated with the second position.

A seat assembly includes a fabric component with a seat surface and with an interior segment directly attached to the fabric component. The interior segment extends from an exterior segment that has a greater flexural resistance than the interior segment.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A chair that provides movement side-to-side about a first pivot axis positioned above the seat plane allows the user a wide range of dynamic movement, but does not require constant or excessive action on the part of the user to maintain a desired position. In addition and concurrently thereto, the chair may include structures that allow the seat to be easily positioned and adjusted side-to-side from a neutral position along a defined pivot axis above a seat plane, and it may, if desired, also provide forward-and-back movement of the seat about a second pivot located above or below the seat plane, an improved seatback that supports the user's back without limiting the user's ability to move their shoulder blades, an improved biasing structure for biasing the seat to a neutral position, an imbedded controller or imbedded sensor for allowing the seat's position to be used as a computer controller, or the gathering of the users motion data, and an adjustable tilt locking system to allow the forward-and-back movement of the seat to be held in a desired position.

A chair includes a leg 1, a seat 5 including a pressure receiving surface PS, a backrest 6, and a support mechanism SM. The seat 5 can move in the front-rear or left-right direction along a predetermined trajectory and to downwardly incline a tip side of the seat 5 in a movement direction in accordance with a movement of the seat 5 from a predetermined reference position (S). The support mechanism SM includes a return-force generation unit configured to generate, in accordance with an amount of movement, a return force in a direction in which the seat 5 moved from the reference position (S) in the front-rear or left-right direction is returned to the reference position (S), and movably supports the backrest 6 in the left-right direction together with a movement of the seat 5 in the left-right direction.
