【考案の詳細な説明】
（産業上の利用分野）
この考案は椅子の背もたれ部が後方に傾倒する
とともに、それに連動して腰当て板が前方に傾倒
する姿勢保持性の良いロツキング椅子に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a rocking chair with good posture retention in which the backrest of the chair tilts backward and the lumbar support plate tilts forward in conjunction with the backrest.
（従来の技術）
従来椅子には、使用者の背中の動きに合せて背
もたれが前後に動くロツキング機構をそなえたも
のがある。しかしながら、このようなロツキング
椅子においては背中を椅子の背もたれにあづけて
後傾させると腰部は背もたれから離れて前方に位

いわゆるランバーサポートという腰当て板を設け
て移動した腰を支持する椅子が使用されてきてい
る。(Prior Art) Some conventional chairs are equipped with a rocking mechanism that allows the backrest to move back and forth in accordance with the movement of the user's back. However, in such a rocking chair, when the back rests against the backrest of the chair and leans back, the lumbar region moves away from the backrest and is positioned forward, and the lumbar region maintains that posture without being supported by anything. and become easily fatigued. For this reason, in recent years, chairs have been used in which a lumbar support plate called a lumbar support is provided below the backrest at the lumbar position to support the lumbar movement.
（考案が解決しようとする問題点）
しかしながらこのような従来のランバーサポー

ートを簡単な機構で、しかも椅子の背もたれの後
傾角度に応じて支持角度が連動して変化し、腰部
の支持能力にすぐれたものである。(Problem that the invention aims to solve) However, such conventional lumbar supports have a fixed degree of protrusion, and the supporting capacity is insufficient, or the protrusion operation of the lumbar support is a mechanism different from the rocking operation of the chair. This has disadvantages in that it is cumbersome to operate and requires the addition of a complicated operating mechanism. This invention solves these drawbacks and provides a simple lumbar support mechanism, and the support angle changes in conjunction with the backward inclination angle of the chair backrest, providing excellent lumbar support.

付け、取り外し自由にすることができる。(Example) The present invention will be described below based on an example shown in the drawings, but the invention is not limited to this example. The chair shown in FIG. 2 is an embodiment of this invention, in which a backrest 10 and a seat 7 are integrally constructed, and a lumbar rest is provided at the lower part of the backrest 10 where the lower back touches. A plate 8 is attached. Figure 1 shows the frame of the chair in Figure 2, and the backrest frame 1.
and the seat frame 9 are integrally constructed of a steel pipe frame, and the vertical frame of the backrest frame 1 is divided halfway into an upper vertical frame 2 and a lower vertical frame 2',
A coil spring 3 is wound around this divided portion to make it integral and to lock it back and forth. A reinforcing plate 4 is installed between the upper vertical frames 2 of the backrest frame 1, and a receiving tube 6 is provided at the lower end of a shaft 5 that hangs down from an appropriate portion of the reinforcing plate 4. Although one shaft 5 and one receiving cylinder 6 may be provided, providing two or more improves stability when the waist support plate 8 is attached. When the shaft 5 is extended downward from the dividing portion between the upper vertical frame 2 and the lower vertical frame 2', that is, the locking portion, the entire waist support plate attached to this comes to protrude forward. The lumbar rest plate 8 has a connecting rod 11 protruding from an appropriate position above a frame 12 made of steel pipe or the like, and the connecting rod 11 is fitted into the receiving cylinder 6 to connect the lumbar rest plate 8 to the backrest portion 1. It can be attached and removed freely.

構の椅子には適用できる。 In the case of the chair of this embodiment, the locking mechanism is based on the elasticity of a coil spring, but it is not limited to this mechanism, and any type of locking mechanism can be applied. In addition to the case where the backrest part 10 and the waist rest plate 8 are made of a frame and its covering material as in this embodiment, the backrest part 10 and the waist rest plate 8 may be made of wood or metal plate. Applicable to chairs with rocking mechanism.

良く、長時間でも疲労しないものである。(Functions and Effects) Most or all of the lumbar support plate 8 is attached below the bent portion (locking portion) of the backrest portion 10 so as to overlap the lower backrest, so that the back rest can be rested on the backrest portion 10. When a load is applied to the upper backrest, the upper backrest tilts backwards, and at the same time the lumbar support plate 8 attached to the upper backrest
will move forward in conjunction with this movement. Therefore, as the back leans backward, the lumbar region of the seater moves forward and is sufficiently supported, resulting in good posture and no fatigue even after long periods of use.

It also provides an interesting design.
