Description

  The present invention relates to a backrest cover.

  There are cases where the backrest is made of resin, wood, or metal from the viewpoint of the durability of the chair and the manufacturing cost, or from the viewpoint of design. When such a chair is seated, the back portion may feel stiff. Therefore, it is conceivable to hang a bag-like cover on the backrest (for example, Patent Document 1).

  However, some chairs are provided with an opening through which the backrest can be reached so that the chair can be easily carried. If such a chair is covered with a simple bag-like cover, the opening is covered with the cover, and the opening cannot be used when carrying the chair.

(First embodiment)
1 is a front view of the backrest cover 1 according to the first embodiment, FIG. 2 is a rear view of the backrest cover 1, and FIG. 3 is a rear perspective view of the backrest cover 1.

  As shown in FIGS. 1 to 3, the backrest cover 1 includes a body portion 12 and a locking portion.

  The main body portion 12 is formed in a tubular shape whose upper and lower end portions are opened in a use state. Here, the tubular shape includes a shape in which an upper end portion and a lower end portion are open, and a so-called bag-like tubular shape in which one of the upper end portion and the lower end portion is open and the other is closed. .. The main body portion 12 is formed of a cloth-like member having a cloth-like surface or a napped surface, and an elastic member such as urethane is attached to the back surface. Therefore, the main body portion 12 is elastic and elastic in the thickness direction.

  The locking portion connects the front surface side of the main body portion 12, that is, the side that comes into contact with the back of the seated person, and the rear surface side of the main body portion 12, that is, behind the backrest, that connects the side that does not come into contact with the back of the seated person. Any member can be used as long as it is a member.

  As the locking portion, for example, a locking piece 11 including a fastener (line fastener), a button, a string, and a locking member can be used. Hereinafter, the case where the locking piece 11 is used as the locking portion will be described as an example.

  The locking piece 11 has a shape that is convex in the upward direction in use, that is, toward the center of the opening 22. The locking piece 11 includes a locking member 11A on the back surface side. As the locking member 11A, for example, a hook of a surface fastener can be used.

  A holding member 12A is provided at a position corresponding to the locking member 11A when the locking piece 11 is bent downward. The holding member 12A is a member having a holding mechanism that holds the locking member 11A. As the holding member 12A, for example, a loop of a surface fastener can be used.

  The backrest cover 1 may further include a fastening portion. As the fastening portion, any member may be used as long as it can fasten the front side of the main body 12 and the back side of the main body 12 at the lower end of the main body 12.

  As the fastening portion, for example, a locking piece 11 including a button, a string, and a locking member can be used. Hereinafter, the case where the fastening member 13 is used as the fastening portion will be described as an example.

  The fastening member 13 is provided at the lower end of the main body 12 when the main body 12 is in use so as to close a part of the opening 22 along the opening 22. As the fastening member 13, for example, a fastener (line fastener) can be used.

  4 is a front view of the chair 2 with the back cover 1 attached, and FIG. 5 is a rear view of the chair of FIG.

  The dimensional relationship will be described with reference to FIGS. 2 and 5. The width W1 of the body portion 12 of the backrest cover 1 is substantially equal to the width W11 of the backrest 21 of the chair 2. The lateral width W2 of the locking piece 11 is substantially equal to the lateral width W12 of the opening 22 provided in the backrest 21.

  The height H1 of the main body 12 is substantially equal to the height H11 from the lower end of the backrest 21 to the lower end of the opening 22. The height H2 of the locking piece 11 is approximately equal to the thickness of the backrest 21 plus the height of the holding member 12A. The height of the holding member 12A has such a length that the locking member 11A does not come off from the holding member 12A even when a person sits on the chair 2.

  The length of the fastening member 13 has a length obtained by subtracting a width enough to pass the backrest support portion 26 supporting the backrest 21 from the lateral width W1 of the main body portion 12. That is, the fastening member 13 is not provided at the left and right end portions of the lower end of the main body portion 12 where the backrest support portions 26 pass.

  Next, the chair 2 to which the backrest cover 1 of the first embodiment is attached will be described.
