In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a chair according to one embodiment. 1, the chair includes a plurality of legs 10, a rotation support member 20, a slope 30, a seat 40, a backrest 50, a stopper 60, a lower end 70 of the stopper, And the inclined surface 30 may be a part of the rotation support member 20. [

The rotation support member 20 may be provided on the plurality of legs 10. The rotation support member 20 can support the seat 40 so as to be rotatable. A seating part 40 may be provided on the rotation support member 20 and the seating part 40 and the rotation support member 20 may be connected to each other through the hinge 100.

As the hinge 100, a hinge 100 in the form of a translator may be used, and holes H1 and H2 may be formed on both sides of the translator. The first hole H1 may be connected to the inner surface of the rotation support member 20 and the hinge 100 may rotate about the first hole H1. The second hole (H2) of the hinge (100) can be connected to the bottom surface of the seating part (40). Unlike the first hole H1, the second hole H2 can be non-rotatably fixed to the seat portion 40. [ Therefore, the hinge 100 can not move around the second hole H2. The hinge 100 may be connected to both sides of the inner surface of the rotation support member 20. [ Therefore, the seating portion 40 can be rotated about a virtual axis connecting the two first holes H1. The method of connecting the rotation support member 20 and the seat 40 so that the seat 40 can be rotated is not limited to this and can be connected using another method.

The rotation support member 20 may include an inclined surface 30. The inclined surface 30 may restrict the seating portion 40 from being rotated over a predetermined angle when the front portion of the seating portion rotates downward. Without the inclined surface 30, there is a risk that the seat 40 will rotate excessively and the occupant may fall over.

The elastic member 80 may be provided between the inclined surface 30 and the seating portion 40. The elastic member 80 may be a spring, a rubber, a sponge, or the like, but is not limited thereto. When the seated person sits in front of the seat 40 and the front of the seat 40 is rotated downward, the elastic member 80 can be retracted. When the seated person stands up or sits behind the seating portion 40, the elastic member 80 can keep the seating portion 40 parallel to the ground. For this purpose, the elastic member 80 is not contracted by the weight of the seat 40, but can be set to be contracted when the seat occupant sits in front of the seat 40. [

The stopper 60 may be provided at a lower portion of the seat 40. The lower end portion 70 of the stopper may be formed of a material having high frictional force such as rubber. When the seated person sits in front of the seat 40 and the seat 40 rotates, the seat can receive a force in the backward direction due to the weight of the seated person. As a result, there is a risk that the chair may be pushed back and the occupant may fall over. The stopper 60 can prevent this. The detailed operation of the stopper 60 will be described later.

2A is a side view showing a state before rotation of a seat 40 in a chair according to an embodiment. Before the seated person sits, the seating portion 40 may be parallel to the ground surface of the elastic member 80.

FIG. 2B is a side view showing a seat 40 in rotation in a chair according to an embodiment. When the weight is applied to the front of the seat 40, the seat 80 is retracted and the seat 40 can be rotated in the clockwise direction in Fig. 2B. The seating portion 40 can be rotated to the inclination angle of the inclined surface 30. [

3A is a side view of a chair according to an embodiment of the present invention when a seated person sits in a right posture. Here, the right posture means an attitude in which the backseat 50 is brought into tight contact with the back of the seating part 40 to the rear end of the seating part 40 and the backrest is brought into close contact with the backrest.

Referring to FIG. 3A, when the seated person is seated in the right posture, the center of gravity is located behind the seating portion 40, so that the seating portion 40 can maintain a horizontal state on the ground.

FIG. 3B is a side view showing a seat according to an embodiment when a seated person is seated in a wrong position. 3B, when the seated person does not sit in the right posture but sits in front of the seat 40, the elastic member 80 contracts and the seat 40 can be rotated clockwise. Here, the elastic force of the elastic member 80 can be set so that it can be contracted by the weight of the seat 40 and the weight of the seated person. The seating portion 40 can be rotated to the inclination angle of the inclined surface 30. [ The seat 40 can be prevented from being seated in front of the seat 40 as the seat 40 rotates so that the seated person can sit in a right posture on the seat.

3B, when the seat occupant sits in front of the seat 40 and the seat 40 rotates, the seat can receive a force in the backward direction due to the weight of the seat occupant. As a result, there is a risk that the chair may be pushed back and the occupant may fall over. In order to prevent this, a stopper 60 may be provided at the lower front portion of the seat portion. When the seating portion 40 is rotated by a predetermined angle or more, the lower end portion 70 of the stopper can come into contact with the ground. The lower end portion 70 of the stopper may be formed of a highly frictional material such as rubber or the like, and the lower end portion 70 of the stopper may not push the seat backward.

4 is a side view of a chair according to one embodiment. Referring to FIG. 4, the chair for seating in the correct posture may further include a protective cover 90 in the chair shown in FIG. The protective cover 90 may be provided on both sides of the seat 40. In the absence of the protective cover 90, the hand of the seated person can be caught in the space between the rotation support member 20 and the seat 40 when the seat 40 is rotated. The protective cover 90 can prevent the hand of a seated person from getting caught.

5 is a perspective view of a chair showing a modified example of the stopper 60 according to an embodiment. Referring to FIG. 5, the guide rods 110 may be positioned on the two legs 10 located in front of the chair in a direction perpendicular to the legs 10. The stopper 60 shown in FIG. 5 may not be connected to the seating part 40 and may be located in a space between the guide bars 110, unlike the stopper 60 according to the embodiment of FIG. When the seat 40 is rotated by a predetermined angle or more, the bottom surface of the seat 40 can be brought into contact with the stopper 60. Accordingly, a weight is applied to the stopper 60, so that a frictional force may be generated between the lower end portion 70 of the stopper and the ground. The chair may not be pushed back by the frictional force between the lower end portion 70 of the stopper and the ground. Since the stopper 60 is in a state of being perpendicular to the paper surface, frictional force is generated, so that the durability of the stopper 60 can be improved. 5, a spring or the like may be connected between the upper guide rod 110 and the stopper 60 so that the stopper 60 is separated from the ground when the seat 40 is not rotated have.

The chair which seats in the right posture has been described with reference to the embodiment shown in the drawings, but the chair is merely an example, and various modifications and equivalent embodiments can be made by those skilled in the art . Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
