A power leisure reclining chair includes a seat structure having a seat portion and a backrest portion, a support assembly having two wooden leg assemblies connected by a wooden cross beam, and a main push rod positioned between the seat structure and the cross beam to push the seat structure to swing. A metal frame and an armrest are arranged on the leg assembly. The support assembly has metal bars extending from a pivot pin on each leg assembly and connecting the seat portion. The metal bar is pivoted to the metal frame. The backrest portion is held at the rear of the leg assemblies by a rail guide system. The rail guide system has guide elements fixed to the leg assembly, and rail member fixed to the backrest portion. The guide element has an under and a top bearing against the bottom and side of the rail member.

A piece of seating and supporting furniture with or without an armrest, comprising an upright and a basic seat and supporting structure (seat and structure) arranged thereon such that it can be pivoted about at least one horizontal axis, wherein the seat and structure has a seat surface which, in a first end position of pivoting about the horizontal axis, is arranged substantially in a horizontal plane, wherein the seat surface, in a second pivoting end position, is arranged transversely to the horizontal plane, wherein the seat and structure has a supporting surface arranged on a side of the seat and structure spaced apart from the seat surface. In another embodiment, a first end of a spring is connected to the upright, a second end of the spring is connected to the seat and structure, and the spring assists pivoting of the seat and structure about the horizontal axis.

Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat. Preferably, the bench further includes a biasing component that biases the stationary base upward relative to the mobile base, a locking mechanism that resists a force provided by the biasing component to retain the bench seat in the unfolded seating position, contoured shells or other covers for the seat and a seat back, and a back panel extending vertically above the seat back.

The present invention relates to a seat lock including: a fixed bracket fixed to a leg of a chair; a locking unit disposed on the fixed bracket; and a movable bracket fixed to a seat of the chair in such a manner as to rotate together with the seat and having a seat rotation shaft and a locking piece coupled to an end periphery of the seat rotation shaft in such a manner as to be exposed to the outside, wherein the locking unit includes a driving motor having a driving shaft, a driving cam fitted to the driving shaft of the driving motor, and a latch rotating in a range of a given angle around a shaft fixed to the fixed bracket to limit the rotational movement of the locking piece. According to the present invention, the seat lock can utilize the locking unit to allow the seat to be more efficiently managed.
