A recliner or lift and recliner chair is provided having a recline or lift and recline chair mechanism with preferably with at least one recline or lift-recline actuator that controls a reclining movement or a lifting and reclining movement. The chair mechanism has a recline or lift-recline base, a seat and a back connected thereto. For additional functionality, a cradle assembly is provided in order to provide a cradling movement to the recline or lift-recline base. The cradle assembly can be provided by a system of standoffs and pivot connections, which can be direct or use links, or can be configured with a track and roller or slide system in order to achieve a desired cradling movement. A cradle actuator is connected between the cradle base and the recline or lift-recline base. A controller is provided that controls movement of the cradle actuator and preferably at least one recline or lift-recline actuator.

A rotatable seat cradle including a lumbar supporting back, a thigh supporting front, an intermediate pelvic support bucket located between the back and the front, and an upwardly sloping transition wall that extends continuously and co-extensively between the pelvic support bucket and the thigh supporting front. The seat cradle is pivotally coupled to a stand or to a yoke connected to a chair base. The thigh supporting front of the seat cradle lies above the pelvic support bucket and cantilevers outwardly from the upwardly sloping transition wall. A seated user shifting his weight towards the front of the seat cradle pushes his legs against the thigh supporting front to generate a rotational force thereagainst for causing a corresponding rotation of the seat cradle relative to the stand or the yoke to which the seat cradle is pivotally coupled.

A hanging chair includes a collapsible spreader bar that reduces the size of the product when in a disassembled configuration. The hanging chair includes a flexible seating portion having first and second side edges. A plurality of ropes connect the first and second side edges of the flexible seating portion to the collapsible spreader bar.

A swing chair includes: a support which is installed at a certain height or more above the floor; a main operation member elongated and having a virtual first rotation axis provided to the support at one side thereof and rotatably coupled to the support; a sub operation member elongated and having a virtual second rotation axis, provided to the support at one side thereof and spaced parallel to the first rotation axis, and rotatably coupled to the support; a seat portion coupled to any one of the main operation member and the sub operation member; and a rotation connecting member elongated and arranged in a front-rear direction and having a rear portion that is rotatably coupled to the other side of the main operation member and a front portion that is rotatably coupled to the other side of the sub operation member.

A collapsible and portable rocking chair includes left and right frame side assemblies collectively defining forward and rear leg members, armrests, seat support members and back support members. The chair also includes transverse connectors connecting the left and right frame said assemblies and supporting the chair in its set-up condition. The connectors are pivotally connected to one another as well as to the left and right frame side assemblies to facilitate folding of the chair frame to a collapsed and bundled condition where all the frame members are pivoted and/or slid relative to one another to a generally parallel condition. Each frame side assembly is supported on a fulcrum point for rocking movement of the chair frame. A rocker mechanism is attached to the chair frame to support the chair during rocking movement and to facilitate rocking of the chair in connection with the user's shifting weight.

An oscillation mechanism for chairs includes a support frame, a structure coupled to the support frame to rotate about a first axis, an elastic element interposed between the support frame and the structure and configured to oppose a reaction force to an oscillation of the structure. The reaction force generates a reaction moment acting on the structure with respect to the first axis. An oscillation adjustment system is able to vary the reaction moment with the oscillation being unchanged. The adjustment system includes a pin movably coupled to the structure and a movement system of the pin for varying the distance between the pin and the first axis. The elastic element is directly fastened to the pin so that the reaction force is transmitted to the structure with the application point corresponding to the pin and with direction and orientation unchanged.

The present disclosure relates to a mechanical extension apparatus for an extendable chair unit and a chair unit including such mechanical extension apparatus. The mechanical extension apparatus includes: a reclining apparatus that include multiple links attached to the seat, the backrest and the footrest of the extendable seat, and such reclining apparatus is configured to convert the extendable seat between a sitting position and a lying position. The mechanical extension apparatus also includes an actuator that is attached to the reclining apparatus, and the actuator is configured to electronically convert the extendable seat between the sitting position and the lying position.

A chair includes a movable part including a seat on which a user sits, a supporting part configured to support the movable part in such a way that the movable part can be moved to the right and to the left; and a restoration unit, which is a biasing member configured to bias the movable part toward the neutral position in the right and the left. The supporting part supports the movable part in such a way that the movable part descends as the movable part is away from the neutral position.

A swingable chair chassis comprises a rocker seat including a chamber defined between a bottom wall and a peripheral wall. The bottom wall includes a slot extending in a front/rear direction. A lid is securely mounted to a bottom of the seat and the rocker seat. A supporting seat is disposed in the chamber of the rocker seat. The supporting seat includes a central portion having an insertion hole coupled with chair post. The supporting seat includes an arcuate supporting face formed on an upper side thereof and abutting against a lower face of the lid. A plurality of elastic elements is disposed between the bottom wall of the rocker seat and the supporting seat and provides movement elasticity when the rocker seat swings forward or rearward relative to the supporting seat. The supporting face abuts against the lower face of the lid during swinging movement of the rocker seat.

A chair includes a support mechanism 2 interposed between a leg 1 and a seat 3, wherein the support mechanism 2 is arranged below the seat 3, is configured to each individually and movably support the seat 3, at least at two locations in a front-rear direction and two locations in a left-right direction, along a predetermined trajectory, and the support mechanism 2 includes: a seat inclining mechanism Q or a seat inclining function configured to downwardly incline a tip side in a movement direction of the seat 3 in accordance with movement of the seat 3, and further includes: a center-of-gravity movement mechanism P or a return-force generation mechanism configured to generate a return force in a direction of returning the seat 3 having moved from a reference position (S) in a front-rear or left-right direction, to the reference position (S) by using a center-of-gravity movement.
