Description

[Detailed Description of the Invention] The present invention relates to chairs for audience seats in theaters, movie theaters, etc. In other words, it is usually a chair for adults to sit on, but if a child is to sit on it, it can be adjusted by changing the posture of the back to make it easier to see and sit comfortably, and it can be divided into upper and lower parts. The present invention provides a structure that can support the back body well, allows for easy modification operations, and has an overall compact structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the entire chair. At the lower ends of both supporting legs 1, 1 on both sides of the chair, grounding frames 3, 3 for fixing to the floor are fixed in orthogonal directions, respectively. Both support legs 1, 1 are placed between the supporting legs 1, 1 to make it horizontal, and both rear sides of the seat body B are fixed to the inner side of the middle part of both supporting legs 1, 1, and supported from the upper end of both supporting legs 1, 1 toward the rear. On both sides of the support stand C, which extends from the frames 4, 4 and is fixed from the upper end surface of both support legs 1, 1, respectively, and stands upward from the rear side of the recording seat body B, near the middle part. Both support frames 4,
4 are connected and fixed at their rear ends.

The back body that can be supported by leaning on the support base C is divided into upper and lower parts to form an upper back body A1 and a lower back body A2.
The lower side parts of the upper back body A1 are pivotally supported on both sides of the support base C via pins 6, 6, and the upper side parts of the lower back body A2 are rotatably supported on both sides of the support base C. One end of the arms 2, 2 is pivotally connected via pins 7, 7, and the other end of both the rotating arms 2, 2 is on the upper side of the seat B. It is constructed by being pivotally connected to the inner part of the body via pins 8, 8, respectively, so as to be freely rotatable.

Therefore, in a normal case where an adult is sitting,
As shown in FIGS. 1 and 2, the upper back body A1 and the lower back body A are placed vertically while leaning against the support base C.
When the two chairs are placed in a row and set in an upright position, it becomes the same as a conventional chair.

In addition, when the dwarf sits down, as shown in FIG. 3, rotate the upper back body A1 around the pin 6 as shown by the arrow A, and then rotate the rotating arm 2 around the pin 8 as shown by the arrow B. While rotating the lower back body A2 around the pin 7 as shown, the lower back body A2 is rotated from below the upper back body A1 to the upper side of the seat B. As shown in Figure 5,
If the lower back body A2 is placed overlappingly above the seat body B, and the upper back body A1 is made to lean against the support C and stand up on the rear side of the lower back body A2, it will be higher than the seat body B. The dwarf can sit down on the upper surface of the lower back body A2, and the upper back body A
1, you will be able to watch from the same height as an adult.

In addition, if you want to return it to the original position so that the adult can sit, you can return it to the original position by performing the above-mentioned reverse operation.

In this way, the present invention fixes the seat B horizontally between the left and right supporting legs 1, 1, and provides a support that can protrude rearward from the upper ends of the left and right supporting legs on the rear side of the seat B. Back support support C supported by rods 4, 4
The upper dorsal body A1 and the lower dorsal body A2 are formed so as to be divided and aligned on the front surface thereof, and the upper dorsal body A
1 has both sides of its lower part rotatably pivoted to the support stand C by pins 6, 6 so that it can lie down forward, and the lower back body has both sides of its upper part attached to the supporting legs 1, 1.
The rotating arms 2, 2, which have one end rotatably pivoted to the upper part with pins 8, 8, are pivoted via pins 7, 7, and the rotating arms 2, 2 are pivoted forward, thereby allowing the rotating arms 2, 2 to rotate downward. Since the upper back body is configured to lie down in front of seat body B, by moving the upper back body and lower back body up and down toward the support base, it can be set into a regular chair that can accommodate an adult. By placing the lower back body on top of the seat body, it is possible to create a chair in which a dwarf can sit as high as an adult. This allows for comfortable and good viewing, and changes can be easily made by simply rotating the upper back body and rotating the lower back body using a rotating arm, and the overall compact structure allows for convenient implementation. It has the features of being able to
