Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

The embodiment of the present invention provides a chair, as shown in Figure 1 and Figure 2, comprising: a seat assembly 110, a backrest assembly 120, a leg rest assembly 130 and a connecting piece 140; The leg rest assembly 130 is hinged, and the two ends of the connecting piece 140 are respectively connected with the backrest assembly 120 and the leg rest assembly 130, and the connecting piece 140 is used for linking the leg rest assembly 130 and the backrest assembly 120; the chair also includes a back support hinged to the backrest assembly 120 A member 150 is used to support the backrest assembly 120.

The chair includes two shapes. The initial shape is usually a seat shape. The backrest assembly 120 and the leg rest assembly 130 are approximately perpendicular to the seat assembly 110, and the overall shape is similar to a common backrest chair. There is also a bed form corresponding to the seat form. The backrest assembly 120 in the seat form of the chair rotates through its hinged end with the seat assembly 110, and the backrest assembly 120 rotates in conjunction with the leg assembly 130 through the connecting piece 140, and Rotate the backrest support 150 to make it approximately perpendicular to the backrest assembly 120, that is, the seat form can be converted into the bed form, and the backrest assembly 120, the seat assembly 110 and the leg assembly 130 in the bed form are approximately on the same plane. Of course, in this embodiment, the initial form of the chair can also be a bed form, and the process of converting the bed form into the seat form is similar to the process of converting the above-mentioned seat form into the bed form. The 110 assembly is approximately vertical, and the backrest support 150 can be folded away.

During normal use, since the backrest assembly 120 and the leg assembly 130 of the chair are linked through the connecting piece 140, the mutual conversion between the seat configuration and the bed configuration is achieved by turning the backrest assembly 120 or the leg assembly 130. Can achieve.

It should be noted that, firstly, usually the connecting member 140 is configured as a multi-hinge structure, through which a smoother linkage effect between the backrest assembly 120 and the leg rest assembly 130 can be achieved. Of course, in practical applications, the connecting member 140 may also be configured as a single rod with a certain bent portion or other structures. There is no limitation to the specific arrangement of the connecting member 140 here.

Second, usually in order to enable the connector 140 to play the role of linking the backrest assembly 120 and the leg rest assembly 130, the two ends of the connector 140 are respectively connected to the backrest assembly 120 and the leg rest assembly 130, one is fixedly connected and the other is hinged. In practical applications, whether the end connected to the backrest assembly 120 is hinged or the end connected to the leg rest assembly 130 is hinged can be set by those skilled in the art according to the situation, and no specific limitation is set here.

Thirdly, in practical applications, the backrest support 150 can also be provided with a telescopic structure, so that the backrest support 150 can adapt to uneven terrain when used in a bed configuration.

Fourth, the back support 150 can be configured as a support rod or the like. When in use, the back support 150 can be manually rotated to a state perpendicular to the back assembly 120 so that it can support the back assembly 120 . Of course, in this embodiment, the back support 150 may also be provided with other structures, which are not specifically limited here.

A chair provided by an embodiment of the present invention includes a seat assembly 110 , a backrest assembly 120 , a leg rest assembly 130 and a connecting piece 140 .
