Tiltable chair
A tiltable chair includes a flexible seat body including an integrally formed seat back and seat surface supported on a seat frame disposed on upper parts of legs, and the seat back connected to a back frame allowing tilting rearwards, the position of the connection being in an area around the upper part of the pelvis of a person seated thereon. A guide rail having an arc-shaped groove is fixed to the seat frame, and guide members which engage and roll in the arc-shaped grooves are pivotably supported on a shaft bracket of the rear surface of the seat surface. The arc-shaped groove has a high center so that the seat surface undergoes curved motion forward and upward such that the ischium is positioned lower than the lower part of the knees when the seat back tilts rearwards.
Chair and supports
A chair has a supporting frame 1, a seat portion 101, a back portion 201 that has an upper end, a lower end, and is pivotally mounted relative to the supporting frame at a position above its lower end, and a recline mechanism 601. The recline mechanism 601 lifts the seat portion 101 upon a reclining action of the back portion 201, and has an operative connection 603, 611 between the seat portion and the supporting frame and a drag link 602 pivotally connected to the seat portion 101 and pivotally connected to the back portion 201 at a position below the pivotal mounting of the back portion relative to the supporting frame. As the back portion 201 of the chair is reclined, the lower end of the back portion 201 moves forward and the drag link 602 pulls the seat portion 101 upward relative to the supporting frame 1.
SEATING SYSTEM
In one or more embodiments, a dining chair is provided having a frame, a seat operably connected to the frame, a backrest operably connected to the frame, a reclining mechanism, and a counterbalance assembly positioned within the backrest, among other components. The backrest is configured to move between an upright position and a reclined position. In one or more arrangements, the counterbalance assembly is configured to provide a counterbalance force to move the backrest to the upright position in absence of an opposing force.
CHAIR AND SUPPORTS
A chair has a supporting frame 1, a seat portion 101, a back portion 201 that has an upper end, a lower end, and is pivotally mounted relative to the supporting frame at a position above its lower end, and a recline mechanism 601. The recline mechanism 601 lifts the seat portion 101 upon a reclining action of the back portion 201, and has an operative connection 603, 611 between the seat portion and the supporting frame and a drag link 602 pivotally connected to the seat portion 101 and pivotally connected to the back portion 201 at a position below the pivotal mounting of the back portion relative to the supporting frame. As the back portion 201 of the chair is reclined, the lower end of the back portion 201 moves forward and the drag link 602 pulls the seat portion 101 upward relative to the supporting frame 1.

Systems and Methods for Providing Ergonomic Exercise Chairs
A chair for providing seating support to a user and for providing ways for the user to perform exercises. The chair includes a back support that is flexible such that when a force is applied to it by the user's body, the back support bends. The back support may be configured to adapt to the curvature of the user's spine when the user is seated in the chair. The back support may further be configured such that the user can rotate the back support by rotating the user's upper body.
Stowaway compact rocker
A stowaway compact rocker having a set-up condition and a collapsed and bundled condition comprises a stationary chair frame base; a movable seating chair frame adapted for rocking movement relative to the stationary chair frame base; and a rocker mechanism operatively connected between the stationary chair frame base and the movable seating chair frame. The stationary chair frame base comprises a central axle tube; a pair of leg plates disposed on the central axle tube; front leg tubes; and rear legs tubes, each leg tube being adapted for connection to a leg plate. The movable seating chair frame comprises a pair of seat tube plates mounted on the central axle tube for rotation thereabout; seat member tubes, each being adapted for connection to a respective one of the seat tube plates; and back-rest tubes, each being adapted for connection to a respective one of the seat tube plates.
Chair including a leaf spring in contact with a linkage to provide resistance to tilting of a backrest of the chair
A chair, comprising, a backrest, a seat coupled with the backrest, a column coupled with the seat, a linkage statically attached to the backrest and rotatably attached below the seat, a leaf spring statically attached at one end and in direct contact with the linkage to provide a resistance to tilting of the backrest relative to the column. A first structure fixed to the column, where a portion of the first structure has an arc shape that includes one or more teeth, and a second structure in contact with the first structure, wherein a portion of the second structure includes one or more teeth. The chair is configured such that, when a weight is applied to the seat, the one or more teeth of the second structure, a pivot point at which the backrest is configured to tilt relative to the column, and the linkage are configured to move together.
