Problems solved by technology

That is, since the seat and the backrest are respectively formed into curved shapes, when the seat surface of the seat and the backrest of the backrest are folded facing each other, the state becomes raised in the thickness direction and becomes not very compact.
In addition, when a plurality of such chairs are stacked and stored, a lot of storage space will be wasted
[0004] In addition, if the seat and backrest are made into a curved shape, the process of tensioning the cover on the seat surface and the backrest becomes complicated.

Embodiment Construction

[0032] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this implementation, if figure 1 and figure 2 As shown, the chair 1 according to the present invention will be used as a mobile viewing seat used in theaters, auditoriums, or stadiums and the like.

[0033] This mobile viewing seat supports stepped floors 2 of different heights with a plurality of leg structures 3 that can move back and forth, and each stepped floor 2 can be pushed forward and unfolded into a stepped seat shape. figure 1 The unfolded position shown, and retracted to the rear in an overlapped state and stored in the specified storage space figure 2 The storage positions are telescopically configured. Meanwhile, on each stepped floor 2, a chair 1 having a chair main body supported between a plurality of pillars 5 provided at predetermined intervals in the left-right direction and adjacent pillars 5 is arranged.

[0034] Refer below image 3 and ...

Abstract

To make a seat and a seat back flat as much as possible while securing sitting comfort as a chair. A cushion material 63 consisting of a substantially filled elastic body is attached to a backup material 61 concerning the seat 6 and seat back of the chair 1 to constitute a substantially flat pressure receiving surface 6a for supporting the body of a sitting person. A hard part 631 is arranged in the cushion material 63, and a soft part 632 being softer than the hard part 631 is disposed at least at part of a pressure receiving area for receiving a load from the sitting person.

Description

technical field [0001] The present invention relates to the structure of chair seat and backrest which are especially suitable for mobile viewing seats, stacking chairs and the like. Background technique [0002] Typically, the seat and back of the chair are curved in a shape corresponding to the contour of the waist or hips of the back. At the same time, necessary parts of the body of the seated occupant are properly accommodated in the concave portion generated by the bending, thereby improving the comfort when sitting. [0003] However, if the seat and the backrest of the chair are curved in order to fit the body shape of the occupant, the volume in the thickness direction thereof increases. This situation, especially for chairs that require storage in a defined space when not in use, such as mobile viewing seats and folding chairs used in gymnasiums and other facilities, as well as stacking chairs, is absolutely undesirable. That is, since the seat and the backrest are...
