Abstract

The invention discloses a seat and its functional frame, comprising a fixed frame, a leg rest connecting frame installed in pairs on the left and right sides of the fixed frame, a connecting piece A, a connecting piece B, a connecting piece C, a connecting piece D, Connecting piece E, cushion connecting frame, backrest connecting frame, connecting piece F, connecting piece G, connecting piece H, connecting piece I, connecting piece J, connecting piece K, connecting piece L, connecting piece M, connecting piece N, connecting piece O, connecting piece P, connecting piece Q; the driving device makes the connecting rod A drive the seat frame to move forward, the backrest connecting frame is away from the wall, the footrest connecting frame moves upward, when connecting piece M and connecting piece L reach the limit point, Connector K, connector M and connector L stop moving forward, other connectors and connecting rods can still move forward, the footrest connector reaches the horizontal position, and the backrest connector moves to a suitable angle. The technical solution optimizes the motion mechanism, reduces stroke distribution, shortens the motor stroke, and reduces weight and cost.

Description

technical field [0001] The invention belongs to the field of furniture, in particular to a seat such as a recliner, a sofa, etc., and in particular to a functional frame used therein. Background technique [0002] Traditionally, furniture such as lounge chairs, sofas, etc. will be installed with an actuating mechanism - a functional frame, on which a chair frame composed of a backrest, a seat cushion, and a leg rest is installed, and the functional frame is used to realize the movement of the chair frame and the motionless The interconnection between the base components. The functional frame is usually a combination of various mechanical linkages that are operable to provide various comfort features, such as independent reclining movement of the seat assembly, and actuation of the extendable leg rest assembly and associated tipping of the chair frame. While many conventional recliners operate satisfactorily, furniture manufacturers are continually pursuing improved chair f...
