Description

Seat member with a width adjustment function for a fixed connected chair and a fixed connected chair including the same The present invention relates to a seat member having a width adjustment function for a fixed connecting chair and a fixed connecting chair including the same, and more specifically, to a seat member having a width adjustment function for a fixed connecting chair that is easy to install and a fixed connecting chair including the same. Generally, fixed connecting chairs (connecting chairs) are installed in rows in theaters, conference rooms, and lecture halls, etc., while ensuring space for users to move around so that a large number of people can sit comfortably to watch movies or conduct education and meetings, and when a user stands up from the seat, the seat automatically rotates and returns to its original position. This seat plate is rotatably connected to a pair of support frames to which a backrest is connected at the rear end. As a method for the seat plate to rotate automatically, a weight is attached to the rear end of the seat plate (see Registered Utility Model No. 20-0377414 (hereinafter Prior Art 1)), or a coil spring is applied to the rotation shaft to rotate automatically by the restoring force of the coil spring (see Registered Patent No. 10-1559103 (hereinafter Prior Art 2)). In the above prior art 2, the rotation angle of the seat plate was also adjusted by applying a bracket connected to the support frame and a stopper provided on the pivot shaft. A method for automatically rotating the keyboard (seat member) to stand upright may be applied in addition to the aforementioned conventional technologies. Meanwhile, in the aforementioned conventional technologies, the pivot axis is fixed to the seat frame (cushion frame), and thus the length of the exposed portion of the pivot axis of each of the multiple seat members (cushion modules) exposed from the seat frame is fixed. However, if a spatial error occurs during the installation process of a fixed connecting chair (connecting chair), multiple fixed connecting chairs cannot be installed in the installation space, resulting in the inconvenience of having to dismantle and remanufacture and install multiple fixed connecting chairs in the installation space. To explain more specifically, if 10 seats are to be installed with a width of 500mm, a width of 5000mm is required. However, when manufacturing and installing fixed connecting chairs with a width of 500mm on-site, if construction errors occur and 10 fixed connecting chairs cannot be installed, there is the inconvenience of installing only 9 chairs instead of the original 10, or collecting the existing chairs and manufacturing fixed connecting chairs with a width of 490mm. FIG. 1 is a front view illustrating a fixed connecting chair according to one embodiment of the present invention. FIG. 2 is a side view illustrating a seat member having a width adjustment function for a fixed connecting chair according to one embodiment of the present invention. FIG. 3 is an exploded drawing for explaining a seat member, backrest, support frame, etc., equipped with a width adjustment function for a fixed connecting chair. FIG. 4 is a plan view of a seat member equipped with a width adjustment function for a fixed connecting chair. Figure 5 is a drawing for explaining the cross-section of the through hole and the shaft member. FIG. 6 is a drawing for illustrating additional embodiments of the present invention. FIG. 7 is a drawing for explaining the slide projection, the first gear, and the second gear in FIG. 6. The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout this specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other elements interposed between them. FIG. 1 is a front view illustrating a fixed connecting chair according to an embodiment of the present invention. FIG. 2 is a side view illustrating a seat member having a width adjustment function for a fixed connecting chair according to an embodiment of the present invention. FIG. 3 is an exploded view illustrating a seat member having a width adjustment function for a fixed connecting chair, a backrest, a support frame, etc. FIG. 4 is a plan view of a seat member having a width adjustment function for a fixed connecting chair.
