Abstract: 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.

Abstract: 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.

Abstract: A chair base is revealed. A round bulge is formed on a center of a bottom surface of a bottom plate and a limit portion is gradually flattened from the round bulge toward a periphery of the bottom plate. A base body is disposed on a top surface of the bottom plate while a cover is used for covering the base body therein and enclosing the periphery of the bottom plate. Thereby the bottom plate, the base body, and the cover are connected and fixed by one another. While in use, users rock the chair by the round bulge on the bottom plate in response to their shifts in center of gravity. A rock angle of the chair is limited by the limit portion. Thereby the users will not tip the chair over while rocking the chair violently and safety in use is ensured.

Abstract: A chair back and seat assembly is revealed. The assembly includes a seat base having an assembly recess with two long locking hole on two side walls, and a back support which includes a connection portion on one end and a driving member at the connection portion and connected with locking bars of the connection portion. During assembly, a pull plate of the driving member is pushed by a recess opening of the assembly recess when the connection portion of the back support is mounted into the recess opening of the assembly recess. Thus the driving member is moved backward and driving the two pre-retracted locking bars to be protruding and further locked by the locking holes of the assembly recess. Thereby the assembly is completed easily and conveniently. The design also prevents the seat base and the back support from unexpected loosening while seated.

Abstract: 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.

Abstract: 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.

Abstract: 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.
