Definitions
- This disclosure relates to chairs.
- Patent Literature 1 discloses a backrest of a chair composed of an upholstery, a backrest frame, and a backing.
- the backing is fixed to the back side of the backrest frame using screws.
- the hooking pieces provided on the upholstery are hooked to the bridging bars provided on the backrest frame, and the backing is also engaged with the backing using rivets, whereby the upholstery is fixed to the front side of the backrest frame.
- Portable chairs used in multipurpose halls are required to have a structure that is easy to carry.
- One aspect of the present disclosure desirably provides a chair with a portion that also functions as a handle for carrying.
- One aspect of the present disclosure is a chair comprising a backrest and a backrest frame.
- the backrest is configured to support the back of the user of the chair.
- a backrest frame supports the backrest.
- the back frame has a right bar, a left bar and an upper bar.
- the right rod member supports the right side of the backrest.

- the upper rod member supports the upper side of the backrest. Further, the upper rod-shaped member protrudes rearward so as to be convex, and connects the right rod-shaped member and the left rod-shaped member.
- the upper bar member can be used as a handle for carrying the chair.
- the backrest may have a body portion and a bent portion.
- the main body has a plate shape that contacts the user's back.
- the bent portion bends and extends rearward from an upper end portion of the body portion. According to such a configuration, since the bent portion has a shape extending rearward, it is possible to hold the chair by placing a hand on the bent portion. That is, the curved portion of the backrest can be used as a handle for carrying the chair. Further, the longer the length of the bent portion, the wider the area of the portion that functions as a handle.

- the chair can be held by placing a hand on at least one of the bent portion and the upper rod-shaped member. That is, both the bent portion and the upper rod-like member can function as a handle. Therefore, since the area of the portion that functions as a handle is widened, it becomes easier to place a hand on the chair, and as a result, the chair becomes easier to carry.
- the backrest may be supported by the backrest frame so as to have a gap between the rear end of the bent portion and the upper bar member.
- the chair can be held by placing a hand in the gap between the bent portion and the upper rod-shaped member. That is, the gap can be made to function as a handle hole.
