で、その座組付け作業が面倒であった。However, in the above-described conventional seat flip-up chair, the components of the seat support device, such as the stopper member and the flip-up member, are laid out inside the seat and are stored. However, the thickness of the seat is increased by design. Further, when the seat is made thin and the above-mentioned seat support device is set under the seat, the respective constituent members are completely visible when the seat is raised and the appearance is poor. In addition, since the components of the seat support device are assembled when the seat is mounted, the operation of assembling the seat is troublesome.

提供することにある。The present invention has been made in view of the above circumstances, and an object of the present invention is to collectively arrange the members for supporting the jumping up as a unit on the left and right outer portions of the seat so that the seat can be moved up and down very smoothly. In addition to being able to be supported rotatably, the seat can be made thinner, and the unit for the seat jumping support member does not make the spring or bearing for seat jumping completely visible from the outside, making it thinner and cleaner. Another object of the present invention is to provide a chair seat supporting device in which a chair having a designed design can be obtained and the assembling work of the seat is very simple. It is another object of the present invention to provide a seat supporting device which can be rotatably supported by tilting a pivot and can be applied to a circularly arranged connecting chair.

A stopper, a bearing for rotatably supporting the pivot thereof, and a spring for springing up the seat that constantly biases the seat support arm in the rising direction via the pivot are built in, and the rotation of the stopper about the pivot is predetermined. A pair of left and right seat support units comprising a rectangular cylindrical arm receiving base having a rotation restricting concave portion for restricting the range within a range, and the arm receiving bases of the left and right seat supporting units are used as left and right support members of a chair. And both sides of the seat are supported by seat support arms of the left and right seat support units. Further, in the chair seat supporting device of the present invention, a spherical bearing is used as a bearing.

Since the support components are combined into a seat support unit, and the seat support unit is attached to the left and right supports of the chair, and the seat support arms of the left and right seat support units support both sides of the seat, It is not necessary to lay out and place the seat-up support components inside the seat, so that the seat can be designed to be thin, and the uniting of the seat-up support components makes the pivots and stoppers not very good in appearance. The design is thin and neat, as only the seat support arm and arm receiving base with good appearance can be seen without the external parts such as the bearings and the spring for raising the seat being exposed from the outside. Chair so that can be obtained. In addition, since the seat is supported by the left and right seat support units that combine the seat flip-up support components, the work of assembling the seat is extremely simple, and the pivoting of the seat is supported by the pivoting of the bearing. Movement becomes very smooth.
In addition, by using a spherical bearing as the bearing, the pivot can be tilted and rotatably supported, so that it can be conveniently applied to a circularly arranged connecting chair.
