Description of the Related Art Conventionally, as a chair in which a backrest can be tilted back and forth with respect to a seat, it comprises a seat, a support member for supporting the seat, and a back support rod having a horizontal portion and a rod portion constituting the backrest. It is widely used that the back support rod is pivotally supported by a support member so as to be tiltable back and forth. Among these things, when in a working position where the backrest does not lean,
When there is almost no gap formed between the rear end of the lower surface of the seat and the horizontal portion of the back support rod, and when in a resting position leaning against the backrest, the rear end of the lower surface of the seat and the horizontal portion of the back support rod are There is a large gap formed between them.

に指や衣服等を詰めてしまうという危険性があった。However, in the case of a chair without a cover having such a structure, when the user takes a resting posture, the backrest tilts backward and the horizontal portion of the back support rod and the lower surface of the rear end portion of the seat are lowered. There is a possibility that the gap formed between and will be greatly opened, and a finger, clothes, or the like will fit into the gap. After that, when returning to the working position, the back support rod returns to the forward tilt direction and the gap formed between the back support rod and the seat is narrowed. If the gap is very small, the gap There was a risk that my fingers and clothes would get stuffed.

とを特徴とする。In order to achieve the above object, the present invention takes the following measures. That is, the chair according to the present invention is one in which a back support rod that constitutes a backrest is pivotally attached to a support member that supports a seat, and a lower end front edge of a hard cover body that covers the back support rod is attached to the seat. It is characterized in that it is pivotally attached to the rear edge, and the lower edge rear edge side of the cover body is removably inserted into a back cover that covers the lower side of the support member.

る。According to the second aspect of the present invention, the lower end portion of the cover body that covers the back support rod is formed between the rear edge of the seat and the back cover that covers the lower side of the support member. Since it is slidably inserted into the opening, when the back support rod is tilted backward, the cover body slides into the opening and a gap is created between the back support rod and the rear edge of the seat. Absent. Therefore, it is possible to prevent the formation of a dangerous gap and improve the safety.

止する。According to the third aspect of the present invention, in the state where the cylindrical body covers the portion of the back support rod below the seat, the rear edge of the seat is moved in accordance with the swing of the back support rod. Since it pivots closely to the lower end, there is no gap between the back support rod and the rear edge of the seat. Therefore, it is possible to prevent a gap from being formed between the back support rod and the seat without changing the appearance of the back support rod from the conventional one.

なり、安全性を高くすることができる。As described above, in the invention according to claim 1 of the present application, since the front edge of the lower end portion of the cover body which covers the back support rod is pivotally attached to the rear edge of the seat, the back support rod is provided. Even if the cover body tilts backward due to a load, the cover body does not rotate around the rear edge of the seat as a rotation center and a gap is not formed. Therefore,
Clothes and fingers are not stuffed between the back support rod and the rear edge of the seat, which increases safety.

形成を防止でき安全性を高くすることができる。According to the second aspect of the present invention, the lower end portion of the cover body that covers the back support rod is an opening formed between the rear edge of the seat and the back cover that covers the lower side of the support member. When the back support rod is tilted backward, the cover body slides into the opening of the back support rod and there is no gap between the back support rod and the rear edge of the seat. Therefore, it is possible to prevent the formation of a dangerous gap and improve the safety.

Since it rotates in close contact with, there is no gap between the back support rod and the rear edge of the seat. Therefore, it is possible to prevent a gap from being formed between the back support rod and the seat without changing the appearance of the back support rod from the conventional one.
