This is solved by the present invention. By introducing the pin into the slot, the front end of the seat and the support leg can be easily connected. To secure the rear end of the seat, one simply pushes the seat into the desired position by means of the slot and pin (slot pin) guides described above.

支脚への取付けが特に簡単となる。In a preferred embodiment, the pin comprises a shank and a wider head, and the slot has a slotted main part and a keyhole with an enlarged hole at one end of the slot. It has a shape. In this case, the inner width of the slot-shaped main portion is slightly larger than the vertical of the shaft portion of the pin, and the inner diameter of the expanded hole is slightly larger than the diameter of the head. In this way, the support device is particularly easy to attach to the support leg at the front end of the seat.

At least one rearwardly extending locking lever is provided. The locking lever is connected to the support leg by a hinge connection, and connects the support leg to the rear end of the seat and the backrest. The back-and-forth pivoting movement of the backrest is then coupled in such a way that it causes a substantially horizontal movement of the front end of the seat and a larger vertical movement of the rear end of the seat. The chair also comprises a spring element arranged between the supporting leg and the locking lever, by means of which the backrest is held in its rest position so as to lean forward.

This increases the angle between the backrest and the seat plate when the backrest is pivoted rearward. During this simultaneous movement, the seat is pulled on the backrest. The resulting longitudinal displacement and pivoting movement of the seat is facilitated by a slot pin guide at the front end of the seat. By using the slot pin guide device according to the invention, the mounting of the seat plate is thereby simplified without impairing the movement of the chair.

The slot 6 has a slot-shaped main portion 6a having a constant width and a wider hole 6b at one end of the slot, and is in the shape of a keyhole. In this case, the inner width of the slot-shaped main portion 6a is slightly larger than the diameter of the shaft portion 5a of the pin 5, and the inner diameter of the expanded hole 6b is slightly larger than the diameter of the head 5b.

下面に対する接触面を形成する（図５）。A groove 2d having the width of the widened hole 6b is provided around the slot 6 in the seat plate 2, and the slot-shaped main portion 6a is defined by the two horizontal projections 2e. The upper surfaces of these horizontal protrusions 2e form a contact surface with the lower surface of the head 5b (FIG. 5).

相補的な曲率をもつように適合させる。As shown in FIGS. 4 and 5, in particular, the head 5b of the pin 5 has a substantially convex lens shape in cross section. Therefore, the upper surface of the horizontal protrusion 2e is adapted to have a complementary curvature with respect to the lower surface of the head 5b.

座板２の補強にも役立つ。The pin 5 is mounted on the tube 1a of the support leg 1 which extends in the transverse direction with respect to the longitudinal center axis 2c of the seat plate 2. On the side of the seat plate 2 facing the tube 1a, a sliding rib 2f is provided at least near the slot. In the illustrated example, two sliding ribs are provided on both sides of the slot 6, respectively, which extend substantially 2/3 of the depth (depth) of the seat plate 2 and extend parallel to the longitudinal center axis 2c thereof. . Sliding rib 2
The f is supported on the support 8 on the tube 1a, which allows the seat plate 2 to move quietly and with very little friction with respect to the tube 1a. The support 8 is provided with a groove 8a for guiding the sliding rib 2f. The sliding rib also
It also helps to reinforce the seat plate 2.

On the other hand, since the head 5b is not only displaced in the vertical (longitudinal) direction but also tilted, the head 5b also has a convex lens-like cross section taken along the line III-III, and the head 5b and the horizontal projection 2e can be rotated at any rotating position of the seat plate. The gap between and becomes as small as possible,
Moreover, the head 5b is made to roll (roll) on the horizontal projection 2e to some extent.

おいて配置される。The seat plate will now be described in more detail with reference to FIGS. The rear end portion 2b of the seat plate 2 is connected to the rest of the seat plate via a bending band extending in a direction crossing the seat plate. In the example shown, this bending band comprises at least one bending bead 2 which extends across the seat plate 2.
It is formed by providing g. Bending bead 2g
Extends in the shape of an arc substantially symmetrical with respect to the longitudinal center axis 2c of the seat plate 2 and extends over the entire width of the seat plate 2. The two bent beads are arranged at relatively small intervals in the direction of the longitudinal center axis 2c.

As shown by the solid line, the sheet is pre-biased so as to incline forward and upward in a stress-free state. The seat plate 2 is preferably made of a plastic material.

び快適さに理想的に合致するようになる。Next, the movement of the chair will be described with reference to FIG. The solid line display indicates a front upright state, and the dotted line display indicates a rearwardly inclined state. In the front upright state, the rear end portion 2b of the seat plate 2 inclined forward functions like a pelvic support. In the rearward inclined state, the rear end portion 2b becomes flat. That is, the angle between the rear end 2b and the rest of the seat plate becomes larger. Therefore, the angle formed by the rest of the seat plate and the backrest 3 also becomes large. In this way, the seat plate 2 and the backrest 3 are ideally matched to the structure and comfort of the seated person.
【００２５】回動軸７の近傍にあるばね要素は、図示し

を防ぐ。Therefore, the seat plate 2 and the backrest 3 can make a certain limited movement with respect to each other and the support leg 1. However, in order to facilitate this movability, it is necessary to provide two slot / pin guide devices near the front end portion 2a of the seat plate 2. When leaning backward, the seat plate 2 is pulled backward by the backrest 3, and when leaning forward, the seat plate is pushed forward again. In this pivoting movement of the backrest, the front end portion 2a of the seat plate 2 makes a substantially horizontal movement, while the rear end portion 2b makes a further upward or downward movement. This prevents the human leg or foot from rising during the pivoting movement.

ることもある。The support device for connecting the supporting leg 1 and the front end portion 2a of the seat portion is not only a point that can be manufactured at a low cost, but especially the seat plate 2
It is outstanding in that it can be easily installed. For this purpose, the two heads 5b of the pin 5 fixed to the tube 1a need only be guided through the two widened holes 6b in the front end 2a of the seat plate 2. Then push the seat plate 2 backwards along the slot 6 to bring the rear end 2
The holes provided in b and the holes provided in the locking lever 4 are aligned so that they can be easily fixed by, for example, screws. The backrest 3 can also be fixed at the same time between the seat plate and the locking lever. In order to improve stability, it may be necessary to connect the backrest 3 to the seat plate 2 as well. An elbow rest 10 may be provided depending on the model of the chair.
