摘要： The present invention relates to a collapsible chair. The chair includes a backrest for engaging with a sitter's back. A seat extends from the backrest and is where the sitter can sit. A retractable leg support may extend from the seat and can be extended to support the sitter's legs with feet off the ground. Advantageously, the sitter's feet may be safely off the ground away from ants and sand.

摘要： 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.

摘要： A seating furniture item with an adjustable-inclination seat part, a back part, a chassis and an at least two-piece leg support connected pivotably on the seat part and/or on the chassis, wherein the parts of the leg support can be displaced relative to one another during pivoting. A part of the leg support is formed by way of a telescopic leg support element which is retracted when the leg support is pivoted in and is extended in order to increase the length of the leg support when the leg support is pivoted out. By way of a first part stroke, a linear actuator brings about a displacement of the seat part relative to the chassis and a simultaneous inclination adjustment of the seat part, wherein no pivoting out or in of the leg support relative to the seat part takes place during this first part stroke of the linear actuator.

摘要： A recliner furniture piece wherein the pair of oppositely disposed side arm sections or frameworks of the furniture piece have their forward end portions extended forwardly beyond the location at which the footrest is disposed when the footrest is located at its fully retracted position, and wherein the pair of oppositely disposed side arm sections or frameworks of the furniture piece have their rearward end portions extended rearwardly beyond the location at which the backrest is attached to the underlying actuator and linkage system. In this manner, the moment arms of the furniture piece are effectively increased while the moment arms of the fully extended footrest and fully reclined backrest are reduced such that the recliner furniture piece can withstand, accommodate, or tolerate increased weights or loads impressed upon the fully extended footrest and/or the fully reclined backrest.

摘要： A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.

摘要： An item of seating furniture includes a chassis, a seat part having a pivotable inclination, a back part pivotable relative to the seat part, and a foot part, which is connected to the seat part via a foot-part adjustment mechanism and can be pivoted out. To adjust the item of seating furniture from an upright sitting position into a lying position, the seat part is moved forward relative to the chassis. In the sitting position, the foot part is pivoted in, substantially underneath the seat part. In the lying position, the foot part is pivoted out, in front of the seat part, such that the seat part is extended by the foot part. When being pivoted into a lying position, the back part moves forward, together with the seat part, relative to the chassis, and therefore, in any pivoted position, the back part does not project, or only insignificantly projects, beyond the rear edge of the item of seating furniture.
