Disclosed in the present disclosure is a support structure and a seat, relating to the technical field of mechanical structures, including a seat frame assembly, a footrest assembly, and a motion-driving assembly, wherein the support structure further includes a first reset elastic member provided on the seat frame assembly and connected to the motion-driving assembly or the footrest assembly, and the first reset elastic member applies a reset elastic force to directly or indirectly drive the footrest assembly to rotate with respect to the seat frame assembly to retract. The support structure and the seat provided in the present disclosure adopts a first reset elastic member to assist footrest retraction, reducing a force required to retract the footrest assembly, with fast retraction speed, providing advantages of convenience, labor-saving and swiftness.

A seating furniture chassis comprises a seat surface frame, a leg rest chassis, first and second struts, and a retractable and extendable leg rest extension. The leg rest chassis is pivotably arranged on the seat surface frame and pivotable from a folded-out position into a folded-in position. The first strut includes a first elongated hole and a first guide element. The second strut includes a second elongated hole and a second guide element, wherein the second guide element is arranged displaceably in the first elongated hole, and the first guide element is arranged displaceably in the second elongated hole. The leg rest extension is arranged on the leg rest chassis and connected thereto by the first and second struts.

The present application relates to the technical field of sofa, and in particular to a compact sofa frame structure, including a base frame and a slidable frame. The base frame is provided with an adjusting assembly. The adjusting assembly includes a driving rod and a driven rod; in which the driving rod and the driven rod are both rotatably connected at one end thereof on the base frame and rotatably connected to the backrest at the other end thereof; a linkage rod rotatably connected on the driving rod; the frame is provided with a driving assembly configured to drive a leg rest rotatably connected on the slidable frame to rotate; the slidable frame is provided with a fixing rod configured to limit the leg rest.

The present disclosure relates to a mechanical stretching device for a movable seat unit, and a movable seat unit thereof. The mechanical stretching device includes: a linkage support that comprises a support structure configured to support the mechanical stretching device on ground and a linkage structure attachable to a seating portion of the seat unit; a back mechanism that is pivotally connected to the linkage support and is configured to attach to a backrest of the seat unit; and a leg stretching structure including a footrest element, and the leg stretching structure is pivotally connected to the linkage support, and the footrest element is attached to a footrest of the seat unit. The mechanical stretching device is configured to implement a sequential conversion or a reverse sequential conversion of the seat unit from a sitting state to a relaxing state and to a lying state.

A convertible chair adapted for conversion between a sitting configuration and a kneeling configuration includes_a base support, a knee-back rest movably coupled to the base support by a pivot arm, a seat movably coupled to the base support by a coupling mechanism, and a connecting arm linking the pivot arm and the seat. The seat is arranged to move relative to the base support between a first seat position corresponding to the sitting configuration and a second seat position corresponding to the kneeling configuration. The pivot arm is arranged to pivot relative to the base support between a first pivot arm position in which the knee-back rest is in a first knee-back rest position for use as a back rest and a second pivot arm position in which the knee-back rest is in a second knee-back rest position for use as a knee rest.

A footrest system is disclosed. The footrest cushion is supported by a frame that is hinge-mounted onto the front of a chair frame. The rotation of the footrest frame by a user creates, through a mechanical system, rotation in a spool. The spool is wound with first and second lines, each being wound in the reverse direction as the other. The lines are connected through rerouting systems and then anchored to the translating member such that they pull the member out upon a deployment, and return the member back in when the footrest is retracted.

A furniture member may include a seat assembly and a legrest assembly. The seat assembly includes a seat bottom and a seatback. The legrest assembly may include a legrest platform and articulating arm assemblies. Each articulating arm assembly may include first and second link-housings and first and second control links. The first link-housings may be rotatably attached to the seat bottom. The second link-housings may be rotatably attached to respective first link-housings and the legrest platform. The first control links may be disposed within respective first link-housings. Rotation of the first link-housings relative to the seat bottom may cause relative movement between the first control links and the first link-housings and relative movement between the first control links and the second link-housings. The second control links may be disposed at least partially within respective second link-housings and may be movably coupled to the second link-housings and to the legrest platform.

The invention relates to a footrest chassis for attachment to a seating furniture chassis, comprising a first region, a second region, at least one attachment means for securing the first region to the seating furniture chassis, and a connecting means, wherein the first region and the second region can be pivoted about a first pivot axis that is defined by the attachment means in the mounted state on the seating furniture chassis, and wherein the second region is connected to the first region by means of the connecting means; during a pivoting movement of the first region and the second region about the first pivot axis, an additional pivoting movement of the second region takes place about a second pivot axis that is defined by the connecting means.

The invention relates to a seating furniture chassis, comprising a retractable and extendable leg and/or footrest, a drive means, a fold-out means for triggering a folding movement of the leg and/or footrest during an extending and/or retracting movement of the leg and/or footrest, and a translation means that is designed to be moved translationally by the drive means and thus trigger the extending and/or retracting movement, wherein the folding movement of the leg and/or footrest can be triggered by a change in the distance between the fold-out means and the translation means.

This invention relates to theater seating, and more particularly to simultaneously controlling a plurality of seats in a theater comprising a user interface and transmitter that can be used to control various elements of the seat, and a receiver and motor control unit attached to each theater seat. In some embodiments, a signal transmitter operated by an individual at a theater may simultaneously control the various elements of any group of seats.
