A chair assembly is provided. The chair assembly includes locking members arranged at a joint between a chair chassis and a seat back support and joints between the chair chassis and two armrests correspondingly. An assembly block of the locking member is formed on the chair chassis while an assembly groove of the locking member is formed in both the seat back support and the respective armrests for being fit on the assembly block of the chair chassis correspondingly. Now a tenon disposed on the assembly block is capable of being engaged with a locking hole arranged at the assembly groove. A positioning part elastically abuts against the opposite side walls of the assembly groove. Thereby assembly of the chair chassis with both the seat back support and the armrests is finished easily and quickly. The chair assembly is more comfortable and safe for users sitting thereon.

A synchronous mechanism for a seating furniture is provided having a seat surface support, a bending element whose length in the sagittal direction extends over a large part of a seat depth of the seat surface support and is coupled to the seat surface support for movement relative thereto. The synchronous mechanism has a backrest support mounted movably relative to the bending element for holding a backrest. The backrest support merges at the end into a pivot lever, coupled to the bending element at a pivot point to be pivotable about an axis of rotation transverse to the sagittal plane, a lever section of the pivot lever is in contact with the seat surface support at a bearing point, and, in the unloaded state of the seating furniture, the pivot point lies higher than the bearing point, as seen in the vertical direction.

An interlocking mechanism for a seat and a back of a chair is provided. A seat body and a chair chassis are pivotally connected, and a pad plate is pivotally connected with the seat body. Thereby the pad plate is moved around a pivotal connection between itself and the seat body when users sit on the pad plate. While a front side of the pad plate is moved downward, it is inclined to an angle slowly by a pad spring connected with the pad plate. When the use is leaning on the chair back connected with the seat body, the seat body is moved backward with a pivotal connection between itself and the chair chassis. The pivotal connection between the seat body and the pad plate can push the pad plate upward so that the seat body is inclined with the chair back and the user sits more comfortably.

A reclining seatback support device which mainly includes at least one seatback support and a seatback body is revealed. The seatback body and an upper end of the seatback support are provided with pivot bracket portions pivotally connected to each other while a lower part of the seatback body and the seatback support are connected by a swing arm. When a user is sitting and lying down on the back, the seatback body is rotated around the pivot axis where the seatback body is pivotally connected to the upper end of the seatback support and then reclined at a certain angle. By elastic segments of the seatback body and the swing arm between the lower part of the seatback body and the seatback support for pulling and limiting the seatback body, the user can lean on the seatback body comfortably and safely.

The present invention discloses a structure for rapidly assembling a chair back and a chair seat. It comprises a chair seat underframe having a first engaging portion and an assembling channel and a chair back stand having a second engaging portion and an assembling block for correspondingly engaging with the assembling channel. The assembling channel has two protrusions at two lateral walls and the assembling block has two engaging grooves at two laterals for positioning and engaging with the two protrusions. The assembling channel of the chair seat underframe has an engaging hole, and a telescopic pin disposed at a bottom of the assembling block is positioned and engaged with the engaging hole. The assembling channel of the chair seat underframe and the assembling block of the chair back stand are further screwed together by a screwing member.

Structure for rapidly assembling chair back and chair seat

The invention relates to a seat (), in particular an office chair, comprising a seat support () for a seating surface () and comprising a backrest support () of a backrest (), which is held on the seat support () so as to be able to move in a tiltable manner to the side, wherein the backrest support () comprises two support arms () which are configured to be flexible and/or articulated laterally and spaced apart from one another. Preferably, the seating surface () and/or the backrest () comprises a curved seat shell and/or backrest shell () provided with a cover () with a number of flexible curved ribs () on the edge of the shell, wherein the cover is stretched by the seat shell and/or backrest shell () such that when the cover () is loaded, the bending of the curved ribs () is altered.

Seat, in particular an office chair

A twistable chair backrest frame is disclosed herein. It has a hollow section and two opposite elastic supporting ribs at a right side and a left side of the hollow section.

Chair back

The invention relates to a seat (), in particular an office chair, comprising a seat support () for a seating surface () and comprising a backrest support () of a backrest (), which is held on the seat support () so as to be able to move in a tillable manner to the side, wherein the backrest support () comprises two support aims () which are configured to be flexible and/or articulated laterally and spaced apart from one another. Preferably, the seating surface () and/or the backrest () comprises a curved seat shell and/or backrest shell () provided with a cover () with a number of flexible curved ribs () on the edge of the shell, wherein the cover is stretched by the seat shell and/or backrest shell () such that when the cover () is loaded, the bending of the curved ribs () is altered.

A chair, in particular an office chair, has a backrest which is coupled to a seat support by way of a backrest support. The chair further has a seat face. For tool-free chair assembly the backrest support is constructed in two pieces having a first support member which is associated with the seat support and having a second support member which is associated with the backrest and which is joined to the seat-support-side first support member in a positive-locking plug type connection and is locked therein.

The adjusting mechanism serves for the setting of a restoring force acting on the backrest of a chair. A back support and a seat support are fastened on a support. A setting mechanism configured in the manner of scissors is provided for the weight setting. Said setting mechanism has two scissor arms which are connected to one another via a scissor pin. One of said scissor arms is formed by a spring element and is fastened with its front-side spring end on said support. The back spring end is fastened on said scissor pin. Said first scissor arm is connected to said back support in the manner of a connecting rod. An active lever length is defined between said scissor pin and a support pin about which said back support is mounted pivotably. A compact construction mode is achieved by the configuration of said scissor arm as a spring element.
