In an embodiment a leg rest includes a mounting fixture, an extension frame and a deployment and stowage mechanism configured to deploy the leg rest from or stow the leg rest to a seat, wherein the extension frame is movably connected to the mounting fixture so that the extension frame moves relative to the mounting fixture when the deployment and stowage mechanism moves the leg rest relative to the seat.

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.

Disclosed is a folding recliner with guide mechanisms, including a backrest portion, a seat portion and a footrest portion, where a supporting leg is arranged at the back of the backrest portion; retraction and supporting rods are fitted with the supporting leg, the other end of each of the retraction and supporting rods is configured to be hinged and fitted with a linkage rod, and the other end of the linkage rod is mounted on the seat portion in a fitted manner; and each of the guide mechanisms includes a guide rod and a guide member, one end of the guide rod is configured to be hinged and fitted with the backrest portion, the other end of the guide rod is a free end, a guide sliding groove is formed in the guide rod, the guide member is capable of moving along the guide sliding groove.

A reclining wheelchair device for facilitating mobility of individuals who are laying down includes a lower frame. An upper frame is pivotably coupled to the lower frame wherein the upper frame is selectively positionable in a vertical position and a horizontal position. The upper frame extends outwardly from the lower frame wherein the upper frame is coplanar with the lower frame when the upper frame is in the horizontal position. The upper frame and the lower frame are designed to support a body of a user while the user is lying down. A seat is coupled to the lower frame to support the body of the user. A back rest is coupled to the upper frame to support the body of the user. A plurality of wheels is rotatably mounted to the lower frame to facilitate movement of the lower frame and the upper frame.

Provided is a sofa extension apparatus. The sofa extension apparatus includes a sofa frame, extension brackets, a first linkage rod, a second linkage rod and a linear drive assembly. Each extension bracket includes a sofa fixing member and a leg portion extension assembly, the sofa fixing member is connected to the sofa frame, the leg portion extension assembly is rotatably connected to a front end of the sofa fixing member. Two ends of the first linkage rod are fixedly connected to rear ends of two sofa fixing members respectively. Two ends of the second linkage rod are connected to two leg extension assemblies respectively. The linear drive assembly is configured to drive the first linkage rod and the second linkage rod to move relative to each other, so as to enable the two extension brackets to be extended or retracted.
