Hereinafter, it will be described with reference to FIGS. 1 to 6 together.

Referring to Figure 1, the back cover 100 according to an embodiment of the present invention, the front portion 101, the connection portion 102, and the rear portion 103 are not divided and are integrally formed in the form of a square plate to be provided. can In FIG. 1, this square plate shape is shown in an unfolded state, but when the connection part 102 extends over the top of the chair back, the connection part 102 naturally bends and the front part 101 covers the front of the chair back. , the rear part 103 may cover the rear surface of the chair back (refer to FIG. 13).

At this time, it is not limited to the rectangular plate shape, and any shape may be possible as long as the shape can cover the front or rear surface of the chair back. In particular, it will be apparent that the corners of the square plate shape can be rounded for design and convenience of use.

In addition, as can be seen in FIG. 1 , the buoyancy body 110-1 to 110-10 provided in at least one of the front part 101, the rear part 103, and the connection part 102 may be provided.

Such a buoyancy body (110-1 ~ 110-10) may provide buoyancy when variable as a life jacket, but when used as a backrest, it will serve as a cushion to improve the feeling of sitting for a person sitting in a chair. .

In addition, as shown in FIG. 1 , the buoyancy body may be provided to be divided into left and right when provided on the front part 101 . In general, the life jacket, it would be desirable to be designed so that a person wearing it can easily get out of the water. Therefore, the water must be drained from the life jacket quickly so that it is possible with less force than when hoisting a person. To this end, in the present invention, the front buoyancy body (110-1, 110-2) provided on the front part 101, the first buoyancy body 110-1 provided on the left and the second buoyancy body provided on the right side Divided by (110-2), it is proposed to form a drainage channel 112 through which water can be drained between the first and second buoyancy bodies 110-1 and 110-2.

If the water drains easily along the ditch 112, it may be done with less force than when pulling a drowning person to land or a vessel.

In addition, the plurality of buoyancy bodies (110-1 ~ 110-10) will be divided according to the position to be bent. For example, the first boundary 120-1 between the front part 101 and the connecting part 102 is a position to be bent by the upper end of the chair back. Similarly, the second boundary 120-2 of the rear portion 103 and the connecting portion 102 is also a position to be bent by the upper end of the chair back.

In addition, as will be described later, between the third buoyancy body 110-3 and the front buoyancy body 110-1 and 110-2 by the incision line 130, the fourth and tenth buoyancy body 110-4, 110- 10) between, between the fifth and tenth buoyancy bodies (110-5, 110-10), between the sixth and seventh buoyancy bodies (110-6, 110-7), the eighth and seventh buoyancy bodies (110-) 8, 110-7) can be divided.

The back cover 100 according to an embodiment of the present invention may be provided with an incision line 130 (for example, a 'U' shape) to form a throat for passing the wearer's head when used as a life jacket. have. As shown in FIG. 1 , through the hole opened by the incision line 130 , the wearer may pass the head through and wear it on the neck.

The incision line 130 for forming a throat according to an embodiment of the present invention suggests a shape in which one side is left and the rest is incised. This is because the uncut portion is fixed to fix the incised portion, and the incision is used to support the back of the wearer's neck. When it is cut in this way, the cut open portion by the non-cut and fixed region may be fixed in the form of hanging from the back cover 100 .

For the description of the present invention, this open portion is referred to as a neck support unit 140 . In one embodiment of the present invention, when the wearer wears the life jacket, it is proposed to support the wearer's head or neck by using the buoyancy of the neck support unit 140 itself. Accordingly, the wearer will be able to survive for a long time by taking a comfortable position when floating in the water. To this end, the uncut portion may be the back of the wearer's neck.

As shown, the neck support unit 140 according to an embodiment of the present invention may be divided into a plurality of buoyancy bodies (110-3, 110-10, 110-7). Since the buoyancy body (110-3, 110-10, 110-7) divided into a plurality of these is easy to bend when opened as above, it will be possible to comfortably give the wearer's neck in a bent state. To this end, the plurality of divided buoyancy bodies (110-3, 110-10, 110-7) may be divided so as to be divided in a horizontal direction.

On the other hand, in one embodiment of the present invention, it is proposed to further include a handle 111 on the neck support 140 . Such a handle 111 is for easily peeling off the backrest cover 100 from the chair back when a person who wants to use it in an emergency situation grabs the handle 111 and pulls it upward.

In addition, in one embodiment of the present invention in order to be effectively fixed to the chair back, as shown in FIGS. 2 and 3 , the first fastening band 201- for fixing the front part 101 and the rear part 103 to each other. 1) is further proposed.

As described above, the backrest cover 100 of the present invention should effectively function as a chair backrest cover in an ordinary, not an emergency situation. Therefore, it is not simply maintained on the back of the chair, but must be effectively fixed to the back of the chair. To this end, in one embodiment of the present invention, the first fastening band 201-1 for fixing the front portion 101 and the rear portion 103 to each other is required. Also, when used as a life jacket, the first fastening band 201-1 may be required in order to be effectively fixed to the wearer's body.

As shown in the drawing, one end of the first fastening band 201-1 is fastened to the lower end of the rear part 103 , and the other end of the first fastening band 201-1 is fastened to the side surface of the front part 101 . can be This is because, as described above, the front portion 101 may be formed to be relatively longer than the rear portion 103 . In particular, the one end of the first fastening band 201-1 may be obliquely fastened from the lower edge of the rear part 103 in a diagonal direction. This is because it has to be connected to the front part 101 in the form of wrapping along the side of the chair back. At this time, one end of the first fastening band 201-1 may be connected to the rounded corner of the square shape.

In addition, in an embodiment of the present invention, a buckle 202 is provided in the middle of the first fastening band 201-1. The buckle 202 is provided in this way, so that the wearer can easily separate the front part 101 and the rear part 103 through the detachment of the buckle 202 . For example, the front portion 101 and the rear portion 103 may be separated through the buckle 202 in order to make it easier to wear/disengage the life jacket.

In particular, it is obvious that the first fastening band 201-1 is provided at each of the left end and the right end of the front part 101, so that both the left and right sides can be fastened/fixed.

In addition, in one embodiment of the present invention, as shown in FIG. 3 , it is proposed to further include a second fastening band 201 - 2 for connecting the front part 101 and the rear part 103 . The second fastening band 201-2 fastened in this way is not simply fixed to the chair back, but is required to be perfectly fixed to the wearer's body when used as a life jacket.

One end of the second fastening band 201 - 2 may be fastened to the lower end of the rear part 103 , and the second fastening band 201 - 2 is divided into two 'Y'-shaped prongs. The two split ends may be respectively fastened to the left and right sides of the lower end of the front part 101 . As such, the reason for the bifurcation is that the second fastening band 201 - 2 wraps around the wearer's groin in the thigh direction. This is because, by the buoyancy force, the life jacket applies a force in the upward direction, and when the force is applied directly upward from the wearer's groin itself, it may cause inconvenience.

The first and second fastening bands 201-1 and 201-2 described above may be made of a material having an elastic force.

In one embodiment of the present invention, it is proposed to turn over the surface used as the chair back cover and use it as a life jacket. This is because the required configuration is different when used as a simple backrest cover and when used as a life jacket. Accordingly, the configurations described with reference to FIGS. 1 to 6 describe a surface that can be utilized as a chair back cover (hereinafter, a back surface), and a surface that can be utilized as a life jacket with reference to FIGS. 7 to 12 below (hereinafter, the life jacket side) will be looked at.
