[0152] Figure 24A -C shows the third embodiment. This embodiment utilizes the deflection deformation of the side beam 14 as an auxiliary drive unit for adjusting the tension of the rear plate 17 . In this embodiment, the seat back 6 also has a rectangular rear frame 13 when viewed from the back, but unlike the first embodiment, the back support 11a of the rocker arm 11 is Y-shaped when viewed from the back, and the upper and lower intermediate heights of the left and right side beams 14 are The part is fixed to the bifurcated front end portion 11c of the back pillar 11a.

[0153] The front end of the rocker arm 11 enters the interior of the base 3 , and the front end is connected to the base 3 through a first shaft 12 . In addition, downward left and right front brackets 4a are provided on the front portion of the seat 4, and the front brackets 4a are connected to the base 3 through left and right vertical sliding shafts 96. In the long hole 97. In addition, the left and ...

no. 4 approach

[0157] Fig. 25 shows a fourth embodiment. Also in this embodiment, the rear frame 13 has the left and right side beams 14 and is formed in a rectangular shape when viewed from the front, and the upper end portion of the back support 11a is fixed to the upper and lower middle portions of the side beams 14 (preferably the lumbar support portion 17a or its vicinity). .

[0158] Moreover, in this embodiment, the side beam 14 of the rear frame 13 is deformed to be able to bend in the left and right directions when viewed from the front, and in addition, the front end portion of the rocker arm 11 is connected to the base 3 through the first shaft 12, so that the first shaft The axis of 12 is only inclined by a certain angle θ with respect to the imaginary horizontal line 102 which is horizontally long on the left and right, so that the more it moves to the left and right outer sides, the more it retreats.

[0159] In this way, by inclining the axis center of the first shaft 12, whe...

Abstract

A backrest (6) includes a back frame (13) opening in front and back, and a netlike member (17) stretched across the back frame. The right and left ends of the lumber support portion (17a) of the netlike member (17) are supported by a spacer (22) from the back. The spacer (22) is incorporated in a cavity (53) formed in a side member (14) and held at the upper end of a rear link (21) such that the height can be adjusted. At the time of rocking, upper end of the rear link (21) retreats relatively to the backrest (6) and thereby the spacer (22) retreats to loosen the netlike material (17) at the position of the lumber support portion. Consequently, push-up feeling of waist is eliminated in a rocking state.

Description

technical field [0001] The invention relates to a rocking chair for tilting the back of the chair. Specifically, it is aimed at either or both of a rocking chair with a flexible backrest used as a seat back and a rocking chair with a headrest that can move back and forth. In addition, as the optimum material for the so-called "backrest" in the present invention, woven fabrics or knitted fabrics or the like made of thin materials such as monofilament and multifilament, but flexible and capable of supporting people are listed. The material with the strength of the back can be used as the "backrest" material. Background technique [0002] In terms of chairs, for example, as exemplified in patent documents 1 and 2, the back of the chair or the seat adopts a structure in which a netted (also grid-like) plate is provided on the frame, and the body of the seated person is supported by the plate (in this paper). In the specification, the backrest using the net-like sheet is partic...
