Description

human body protection device

[0001] The present disclosure relates to a human body protection device for protecting the human body and preventing human injury due to a fall / collision / impact.

[0002] Elderly and sick people with mobility difficulties are physically weaker than healthy individuals. Consequently, they are more likely to lose their balance and fall frequently when navigating steep surfaces like stairs or hills, or dangerous areas like icy roads.

[0003] Additionally, falls can cause injuries not only outdoors but also at home, including in bedrooms and bathrooms.

[0004] Technologies such as hip protectors are being developed to protect the human body, specifically the hips, from falls.

[0005] Hip protectors can be worn as an integral part of clothing, or detachably attached using a separate attachment means.

[0006] However, in the case of wearable devices, there are problems such as the weight and bulk making it inconvenient for the elderly and patients to wear continuously, and the inconvenience of carrying it.

[0007] In the case of a detachable type, the buttocks may not be properly covered and the buttocks may be exposed as the buttocks are lifted toward the upper body based on the means of attachment and detachment, which may cause problems in protecting the buttocks from accidents.

[0008] Therefore, there is a need for technology for human body protection devices to properly protect the hips from frequent accidents.

[0009] The present disclosure aims to provide a human body protection device that effectively protects the buttocks by properly wrapping the buttocks along the buttocks line in a form that minimizes weight and volume and can be worn continuously without discomfort.

[0010] In order to achieve the above-described purpose, a human body protection device according to one feature of the present disclosure comprises: a wearing part; an expansion part provided inside the wearing part and including a plurality of partial expansion parts; and a guide member provided between two adjacent partial expansion parts; wherein the guide member guides an end of the expansion part to be rounded in a direction in which it comes into contact with a body part of a user when the expansion part is expanded.

[0011] Additionally, the guide member is made of an elastic material.

[0012] In addition, the partial expansion part includes a first partial expansion part that wraps around the buttocks; a second partial expansion part provided on one side of the first partial expansion part; and a third partial expansion part provided on the other side of the first partial expansion part; and the guide member is provided between the first and second partial expansion parts and between the first and third partial expansion parts.

[0013] Another feature of the present disclosure is a human body protection device comprising: a wearable part; an inflatable part provided inside the wearable part; and a guide member having one end coupled to at least one of the wearable part and the inflatable part and the other end coupled to the other end; wherein the guide member guides an end of the inflatable part to be rounded in a direction in which it comes into contact with a body part of a user when the inflatable part is inflated.

[0014] The human body protection device of the present disclosure has a guide member provided between two adjacent partial expansion parts, and when the expansion part is expanded, the guide member guides the end of the expansion part to be rounded in the direction of contact with the body part, thereby preventing the problem of the expanded expansion part being lifted toward the upper body when fully expanded, thereby more effectively protecting the buttocks, and before expansion, the expansion part is provided inside the wearable part in a folded state, thereby minimizing the weight and volume. Accordingly, the present disclosure provides a human body protection device that can be continuously worn without the inconvenience of weight and volume, and can effectively protect the body part without the problem of the expansion part being lifted toward the upper body when inflated.

[0028] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0029] The width direction of the human body protection device according to a preferred embodiment of the present disclosure described below (hereinafter referred to as the “human body protection device (1) of the present disclosure”) is the ±x direction indicated in the drawing, the length direction of the human body protection device (1) of the present disclosure is the ±y direction indicated in the drawing, and the thickness direction of the human body protection device (1) of the present disclosure is the ±z direction indicated in the drawing.

[0030] Hereinafter, the expansion part (E) includes the expansion parts (E1-1, E1-2, E1-3, E2) of the first to second embodiments.

[0031] FIG. 1 is a perspective view of a human body protection device (1) of the present disclosure, FIG. 2 is a plan view of a human body protection device (1) of the present disclosure, and FIG. 3 is a plan view of a human body protection device (1) of the present disclosure having an expansion portion (E1-1) according to a preferred embodiment 1-1 of the present disclosure.

[0032] Referring to FIGS. 1 to 3, the human body protection device (1) of the present disclosure includes a wearable part (100), an expansion part (E) provided inside the wearable part (100) and including a plurality of partial expansion parts (PE), and a guide member (300) provided between two adjacent partial expansion parts (PE).

[0033] The wearable part (100) is provided so that it can be worn on a part of the user's body, with an inflatable part (E) inside that expands when an unexpected accident such as a collision, fall, or crash occurs. The wearable part (100) is preferably made of fabric and is provided so that it can be worn on the user's pelvic area.

[0034] The wearable part (100) is provided with a wearing means (101) that allows for wearing and unwearing in the front (+z direction) based on the thickness direction (±z direction) so that it can be worn on the user's pelvic area. The wearing means (101) may be configured as a buckle or a zipper, but is not limited thereto. The wearable part (100) is provided with the wearing means (101) in the front (+z direction) and is formed in the form of a belt that can be worn on the pelvic area among body parts. The shape of the wearable part (100) is not limited thereto.

[0035] The human body protection device (1) of the present disclosure comprises an inflatable portion (E) folded and overlapped in a form that is rolled up in at least one direction inside the wearable portion (100). Accordingly, the human body protection device (1) of the present disclosure can be worn continuously with minimal weight and volume, thereby effectively preventing the risk of injury due to an unexpected accident. In addition, the human body protection device (1) of the present disclosure can provide high convenience because there is no inconvenience in continuous wearing due to its light weight and small volume.

[0036] The wearing part (100) has a quick burst part (102) formed continuously along the width direction (±x direction) at the lower part. Accordingly, when the human body protection device (1) of the present disclosure is worn, the quick burst part (102) is positioned to correspond to the lower part of the user's pelvis and the upper area of ​​the buttocks.

[0037] In other words, the quick burst part (102) is provided at the lower end of the wearing part (100) so as to correspond to the area where the user's pelvis and buttocks are connected when the human body protection device (1) of the present disclosure is worn. The quick burst part (102) may be configured in the form of a zipper, a male and female button combination, and a Velcro, for example. The form of the quick burst part (102) is not limited thereto. The human body protection device (1) of the present disclosure may have the quick burst part (102) configured in the form of a zipper.

[0038] The human body protection device (1) of the present disclosure, when a fall accident occurs, expands the expansion portion (E) and protrudes outward from the wearing portion (100) through the quick burst portion (102). When a collision, fall, or crash accident occurs, the zipper connection state of the quick burst portion (102) is released by the expanding force of the expansion portion (E), and the expansion portion (E) protrudes downward (-y direction) from the quick burst portion (102) of the wearing portion (100) based on the longitudinal direction (±y direction) and expands. Accordingly, when the expansion portion (E) is expanded, it is positioned to correspond to the buttocks, which are located lower than the pelvic region.

[0039] The wearing part (100) seals the upper part in the opposite direction to the quick burst part (102) of the lower part. This is achieved by not providing a separate component (e.g., quick burst part (102)) to the fabric constituting the wearing part (100). The wearing part (100) seals the upper part to prevent water from entering the inside of the wearing part (100). Therefore, the human body protection device (1) of the present disclosure can be continuously worn even during a shower. As a result, the human body protection device (1) of the present disclosure can effectively protect the user's buttocks area from falling accidents that frequently occur when slipping on water during a shower.

[0040] Fig. 2 is a plan view of a human body protection device (1) of the present disclosure. In Fig. 2, the expansion portion (E) is omitted and illustrated.

[0041] Referring to FIG. 2, the human body protection device (1) of the present disclosure includes a detection sensor (10) that detects an impact inside a wearable part (100), a battery (60) that supplies power to a power supply part (20) for inflating an inflatable part (E), a main board (70) operated by the power supply part (20), and an inflator part (30) that includes a gas cartridge (50) and a gas connection part (40) that supplies air to be injected into the inside of the inflatable part (E).

[0042] The detection sensor (10), the battery (60), the main board (70), and the inflator unit (30) are provided inside the wearable unit (100). Referring to FIG. 1, the power supply unit (20) may be provided around the wearing means (101) of the wearable unit (100), and the location where it is provided is not limited thereto. The power supply unit (20) may be provided in the form of a power switch (or a touch switch). The human body protection device (1) of the present disclosure is provided with the power supply unit (20) in the form of a power switch. By turning the power switch of the power supply unit (20) ON / OFF, the human body protection device (1) of the present disclosure can be in an operating state ON / OFF.

[0043] Alternatively, the power supply unit (20) may automatically become 0N / 0FF depending on the coupling state of the wearing means (101) of the wearing part (100). Specifically, when the wearing means (101) is in a coupling state, the operating state of the power supply unit (20) may become 0N. Conversely, when the coupling state of the wearing means (101) is released, the operating state of the power supply unit (20) may become OFF.

[0044] The detection sensor (10) is provided inside the wearing part (100), preferably in the central part of the inside. The location where the detection sensor (10) is provided is not limited thereto. The human body protection device (1) of the present invention can connect the wearing means (101) and the main board (70) so that the operation of the detection sensor (10) automatically starts when a wearing signal is generated through the wearing means (101). In addition, the operation of the detection sensor (10) can be stopped when a wearing release signal of the wearing means (101) is generated.

[0045] The battery (60) may be provided on one side (- x direction) of the detection sensor (10) based on the width direction (± x direction). Preferably, the battery (60) may be provided on one side of the detection sensor (10) and on the outer part. Accordingly, when the human body protection device (1) of the present disclosure is worn, the battery (60) may be positioned in front of the pelvic region (+ z direction). Accordingly, when lying down while wearing the human body protection device (1) of the present disclosure, discomfort due to physical contact with the battery (60) can be prevented in advance.

[0046] The inflator unit (30) includes a gas cartridge (50) and a connecting portion (40) connecting the gas cartridge (50) and the expansion portion (E). The connecting portion (40) corresponds to the injection hole (IH) and is directly connected to the expansion portion (E). The inflator unit (30) connects the gas cartridge (50) to one side of the connecting portion (40) and injects expansion material (air and fluid) into the expansion portion (E) through the injection hole (IH).

[0047] The gas cartridge (50) has the function of supplying air to the injection hole (IH) of the expansion part (E). At least one gas cartridge (50) is provided. The human body protection device (1) of the present disclosure is provided with two gas cartridges (50) as an example. The gas cartridge (50) includes a first gas cartridge (51) provided in at least one direction among one side (-arc direction) and the other side (+x direction) of the detection sensor (10) based on the width direction (±x direction), and a second gas cartridge (52) provided in the other direction. Referring to FIG. 5, the human body protection device (1) of the present disclosure is provided with a first gas cartridge (51) in one side (-X direction) of the detection sensor (10) and with a second gas cartridge (52) in the other side (+x direction).

[0048] The first gas cartridge (51) may be installed around the battery (60) and spaced apart from the battery (60). Accordingly, the first gas cartridge (51) may be installed on the inner outer portion of the wearable part (100). The human body protection device (1) of the present disclosure has the battery (60) installed on one side (-X direction) of the detection sensor (10) and on the inner outer portion of the wearable part (100). In this case, the first gas cartridge (51) may be installed on the upper portion (+y direction) of the battery (60), for example.

[0049] The second gas cartridge (52) may be provided on the other side (+x direction) of the detection sensor (10). The second gas cartridge (52) may be provided on the other side (+x direction) of the detection sensor (10) and on the inner outer portion of the wearing part (100). The human body protection device (1) of the present disclosure may be provided with two gas cartridges (50) such that the first gas cartridge (51) and the second gas cartridge (52) are provided in opposite directions, but are each provided on the inner outer portion of the wearing part (100). Accordingly, when the human body protection device (1) of the present disclosure is worn, the gas cartridge (50) may be located around the wearing means (101) and in front (+z direction) of the pelvic region.

[0050] A gas cartridge (50) is provided on the inner outer portion of the wearable part (100) and connected to the injection hole (IH) of the expansion part (E). At this time, the gas cartridge (50) is not provided on the expansion area (PS) of the expansion part (E), but is located on the non-expansion area (NE) existing in the injection hole (IH) and is provided so as to be connected to the injection hole (IH).

[0051] The main board (70) is operated by the power supply unit (20), and is connected to the detection sensor (10) and the gas cartridge (50) to supply air of the gas cartridge (50) to the injection hole (IH) when an impact occurs by the detection sensor (10). The main board (70) is provided on the other side (+x direction) of the detection sensor (10), but is spaced apart from the second gas cartridge (52) and is provided at the bottom of the second gas cartridge (52). The position where the main board (70) is provided is not limited thereto. The main board (70) may be provided on one side (-x direction) of the detection sensor (10) and may be provided around the first gas cartridge (51). In this case, the battery (60) may be provided around the second gas cartridge (52). In other words, the main board (70) and the battery (60) may preferably be provided in opposite directions. This is to ensure an even weight balance between the outer side (- direction) of one side and the outer side (+x direction) of the wearing part (100). As a result, the human body protection device (1) of the present disclosure can prevent the problem of the front (+z direction) side of the pelvis leaning to one side when worn.

[0052] FIG. 3 is a plan view of a human body protection device (1) of the present disclosure having an expansion portion (hereinafter, referred to as an expansion portion (E1-1) of the first embodiment) according to a preferred embodiment 1-1 of the present disclosure therein. In FIG. 3, the interior of the wearable portion (100) is exposed through a quick burst portion (102), and the joint structure between the wearable portion (100) and the expansion portion (E1-1) of the first embodiment before expansion is illustrated.

[0053] Referring to FIG. 3, the wearing part (100) has a sewing part (hereinafter referred to as a “width-direction sewing part (WP)”) that is continuously formed in the width direction (±x direction) at the center based on the length direction (±y direction). The width-direction sewing part (WP) is a part that is joined through a sewing method or another joining method to provide a fabric (preferably, a waterproof fabric) constituting the wearing part (100) in an integral form. The wearing part (100) has a first joining member (103a) in the width-direction sewing part (WP).

[0054] The wearing part (100) is provided with a first connecting member (103a) to provide the expansion member (E) of the first embodiment within the wearing part (100). The first connecting member (103a) may be configured in the form of a Velcro. The form of the first connecting member (103a) is not limited thereto, and may be provided as a detachable means.

[0055] The wearing part (100) has at least one first connecting member (103a). The human body protection device (1) of the present disclosure has, as an example, six first connecting members (103a). Referring to FIG. 6, the wearing part (100) sequentially has a first-first connecting member (B1-1), a first-second connecting member (B1-2), a first-third connecting member (B1-3), a first-fourth connecting member (B1-4), a first-fifth connecting member (B1-5), and a first-sixth connecting member (B1-6) from an outer portion on one side (-arc direction) to an outer portion on the other side (+x direction) with respect to the width direction (±x direction). The first connecting member (103a) includes the first-first to the first-sixth connecting members (B1-1, B1-2, B1-3, B1-4, B1-5, B1-6).

[0056] The first connecting member (103a) is composed of a pair of Velcros provided in the upper and lower directions based on the longitudinal direction (±y direction). Specifically, the Velcros are composed of a first Velcro provided on the upper portion (+y direction) of the widthwise sewing portion (WP) and a second Velcro provided on the lower portion of the widthwise sewing portion (WP) and connected to the lower portion of the first Velcro.

[0057] The human body protection device (1) of the present disclosure is provided with a first connecting member (103a) as a pair of Velcros provided in the upper and lower directions, and a second connecting member (103b) of the expansion part (E1-1) of the first embodiment is provided between the pair of Velcros (specifically, the first and second Velcros) to implement the connection between the wearing part (100) and the expansion part (E1-1) of the first embodiment. The human body protection device (1) of the present disclosure interposes a second connecting member (103b) between a pair of Velcros of a first connecting member (103a), adheres the first Velcro to one side of the second connecting member (103b), and adheres the second Velcro to the other side of the second connecting member (103). As a result, the expansion part (E1-1) of the first embodiment is coupled to the inside of the wearing part (100) through the first and second connecting members (103a, 103b).

[0058] Referring to FIG. 3, the expansion member (E1-1) of the first embodiment has a second coupling member (103b) at one end (upper end (+y direction) based on the longitudinal direction (±y direction). The second coupling member (103b) is provided in a position corresponding to the number and position of the first coupling member (103a). Accordingly, six second coupling members (103b) are provided, for example. The second coupling member (103b) is provided in a position corresponding to the first coupling member (B1-1), a second-second coupling member (B2-2) provided in a position corresponding to the first-second coupling member (B1-2), a second-second coupling member (B2-2) provided in a position corresponding to the first-third coupling member (B1-3), a second-third coupling member (B2-3) provided in a position corresponding to the first-third coupling member (B1-3), It includes a second-fourth connecting member (B2-4) provided at a position corresponding to the first-fourth connecting member (B1-4), a second-fifth connecting member (B2-5) provided at a position corresponding to the first-fifth connecting member (B1-5), and a second-sixth connecting member (B2-6) provided at a position corresponding to the first-sixth connecting member (B1-6).

[0059] The human body protection device (1) of the present disclosure couples the expansion portion (E1-1) of the first embodiment to the inside of the wearing portion (100) by interposing the second coupling member (103b) between a pair of Velcros of the first coupling member (103a) by corresponding the first to 1-6 coupling members (Bl-1, Bl-2, B1-3, B1-4, B1-5, B1-6) and the second to 2-6 coupling members (B2-1, B2-2, B2-3, B2-4, B2-5, B2-6), respectively. At least one of the first and second coupling members (103a, 103b) has a hook, and the other has a hook. The human body protection device (1) of the present disclosure is provided with an expansion portion (E1-1) of the first embodiment detachably attached to the wearing portion (100) through the first and second connecting members (103a, 103b).

[0060] The expansion portion (E1-1) of the first embodiment is configured by integrally joining the first fabric and the second fabric. The first and second fabrics are provided in a symmetrical shape. One side of the first and second fabrics is preferably configured as a waterproof coating side. The first and second fabrics are integrally joined by being in face-to-face contact with each other in a state where the sides having the waterproof coating side are overlapping each other as contact sides. The expansion portion (E1-1) of the first embodiment has the waterproof coating side of the first and second fabrics as the contact side, so that the inner side is provided with the waterproof coating side. As a result, when the expansion portion (E1-1) of the first embodiment is expanded by a material (e.g., air, fluid, etc.) that expands the expansion portion (E1-1) of the first embodiment, the problem of the contact sides of the first and second fabrics sticking to each other is prevented. In addition, the expansion portion (E1-1) of the first embodiment is formed with a waterproof coating surface on the inside, which is advantageous in preventing the expansion material inside from leaking out to the outside.

[0061] The first and second fabrics can be joined together in the following manner.

[0062] The first and second fabrics are overlapped with each other with their waterproof coating surfaces as contact surfaces, and silicone is applied to the edges of the first and second fabrics. That is, the silicone is applied between the first and second fabrics. Then, when the applied silicone hardens, the area where the silicone is applied is sewn. In other words, the silicone is applied to a temporarily marked sewing area on the edges of the first and second fabrics that are overlapped with each other. Then, when the silicone hardens, the area where the silicone is applied is sewn using a thread to integrally join the first and second fabrics. As a result, the expansion portion (E1-1) of the first embodiment is formed. The thread penetrates the first fabric, the silicone, and the second fabric in that order or in the reverse order.

[0063] The first and second fabrics described above may be replaced with first and second resin materials. In this case, the first and second resin materials may be joined by heat fusion, and the heat fusion portion may correspond to the fabric sewing portion (SW) described below.

[0064] The expansion portion (E1-1) of the first embodiment is provided with a fabric sewing portion (SW) on the edge side by applying silicone to the edge side and then sewing. The expansion portion (E1-1) of the first embodiment can effectively prevent the expansion material injected inside from leaking out due to the presence of silicone in the fabric sewing portion (SW). In addition, durability can be improved. The method of integrally joining the first and second fabrics is not limited thereto.

[0065] Referring to Fig. 3, the expansion portion (E1-1) of the first embodiment has an expansion region (PS) and a non-expanded region (NE) based on the fabric sewing region (SW). In other words, the expansion region (PS) and the non-expanded region (NE) are divided by the fabric sewing region (SW).

[0066] The area provided on the outside of the fabric sewing area (SW) based on the fabric sewing area (SW) is a non-expanded area (NE) in which the first and second fabrics constituting the expansion area (E) are not combined. The non-expanded area (NE) is a area provided on the outside of the fabric sewing area (SW) and is the edge area (EF) of the expansion area (E).

[0067] The expansion region (PS) is provided on the inner side of the fabric sewing region (SW) based on the fabric sewing region (SW). Therefore, the expansion region (PS) is provided on the inner side of the non-expanded region (NE). The expansion region (PS) includes the first and second fabrics existing in the remaining area excluding the area of ​​the first and second fabrics existing in the non-expanded region (NE) among the total area of ​​the first and second fabrics constituting the expansion portion (E). The first and second fabrics existing in the remaining area exist in a non-bonded state. In other words, the first and second fabrics existing in the expansion region (PS) are not bonded. Accordingly, a space into which air or fluid can be injected is formed inside the expansion region (PS). The expansion region (PS) is sealed by the fabric sewing region (SW).

[0068] The expansion section (E1-1) of the first embodiment comprises an expansion region (PS) and a non-expanded region (NE), and the expansion region (PS) and the non-expanded region (NE) are separated by a fabric sewing portion (SW), and a plurality of partial expansion regions (PE) are provided through the expansion region (PS). Accordingly, a non-expanded region (NE) is provided on the outside of the plurality of partial expansion regions (PE).

[0069] Specifically, referring to FIG. 3, the expansion part (E1-1) of the first embodiment includes a plurality of partial expansion parts (PE). More specifically, the expansion part (E1-1) of the first embodiment includes a plurality of partial expansion parts (PE), including a first partial expansion part (PE1) that wraps around the user's buttocks, a second partial expansion part (PE2) that is provided on one side (-X direction) of the first partial expansion part (PE1) to wrap around the outer side of one thigh, a third partial expansion part (PE3) that is provided on the other side (+x direction) of the first partial expansion part (PE1) to wrap around the outer side of the other thigh, and a fourth partial expansion part (PE4) that integrally connects the first to third partial expansion parts (PE1, PE2, PE3) to the upper portions of the first to third partial expansion parts (PE1, PE2, PE3).

[0070] The expansion section (E1-1) of the first embodiment has a non-expanded region (NE) between each of the first to fourth partial expansion sections (PEI, PE2, PE3, PE4). The non-expanded region (NE) provided between each of the first to fourth partial expansion sections (PE1, PE2, PE3, PE4) is at least a part of the non-expanded region (NE) or the edge region (EF) of the expansion section (E1-1) of the first embodiment surrounding the expansion region (PS) on the outside of the expansion region (PS).

[0071] Specifically, the non-expandable region (NE) is provided between the first and second partial expansion portions (PEI, PE2) and at the lower portion of the fourth partial expansion portion (PE4), and is provided between the first and third partial expansion portions (PEI, PE3) and at the lower portion of the fourth partial expansion portion (PE4). In addition, the non-expandable region (NE) is provided between the second and fourth partial expansion portions (PE2, PE4) and between the third and fourth partial expansion portions (PE3, PE4) based on the longitudinal direction (±y direction).

[0072] The expansion portion (E1-1) of the first embodiment comprises first to third expansion portions (PEI, PE2, PE3) in a mutually cut form. Accordingly, a cut portion (IP) is formed in the non-expanded region (NE) provided between each of the first to third expansion portions (PEI, PE2, PE3).

[0073] The expansion portion (E1-1) of the first embodiment has a guide member (300) between two adjacent partial expansion portions (PE). Specifically, the guide member (300) is provided in a cut portion (IP) formed in a non-expanded region (NE) provided between each of the first to third partial expansion portions (PEI, PE2, PE3).

[0074] Referring to Fig. 3, a first non-expandable region (NE1) is provided between the first and second partial expansion portions (PEI, PE2), and a second non-expandable region (NE2) is provided between the first and third partial expansion portions (PEI, PE3). The first non-expandable region (NE1) includes a first incision portion (IP1), and the second non-expandable region (NE2) includes a second incision portion (IP2).

[0075] The first non-expanded region (NE1) includes a first-first cutting line (C1-1) located on one side (-X direction) based on the width direction (±x direction) of the edge region (EF) that surrounds the outside of the first partial expansion portion (PE1) by the first cutting portion (IP1). In addition, the first non-expanded region (NE1) includes a second-first cutting line (C2-1) located opposite to the first-first cutting line (C1-1) and on one side (+X direction) based on the width direction (±x direction) of the edge region (EF) that surrounds the outside of the second partial expansion portion (PE2). In other words, the first non-expanded region (NE1) includes the first-first cutting line (C1-1) and the second-first cutting line (C2-1) that is opposite to the first-first cutting line (C1-1).

[0076] The second non-expanded region (NE2) includes a first-second cutting line (C1-2) located on the other side (+x direction) of the edge region (EF) that surrounds the outside of the first partial expansion portion (PE1) by the second cutting portion (IP2) in the width direction (±x direction). In addition, the second non-expanded region (NE2) includes a third-first cutting line (C3-1) located opposite the first-second cutting line (C1-2) and on one side (-x direction) of the edge region (EF) that surrounds the outside of the third partial expansion portion (PE2) in the width direction (±x direction). In other words, the second non-expanded region (NE1) includes a first-second cutting line (C1-2) and a third-first cutting line (C3-1) that is opposite to the first-second cutting line (C1-2).

[0077] The human body protection device (1) of the present disclosure has a guide member (300) between the first and second partial expansion parts (PEI, PE2) and between the first and third partial expansion parts (PEI, PE2). More specifically, the human body protection device (1) of the present disclosure has a guide member (300) in the first and second non-expandable regions (NE1, NE2).

[0078] The guide member (300) guides the end of the expansion part (E1-1) of the first embodiment to be rounded in the direction of contact with the user's body part (rearward (-z direction) based on the thickness direction (±z direction) of FIG. 3) when the expansion part (E1-1) of the first embodiment is expanded.

[0079] The guide member (300) is preferably made of an elastic material and guides the end of the expansion portion (E1-1) of the first embodiment to be rounded in the direction (-z direction) in which it comes into contact with the body part. Referring to Fig. 3, the human body protection device (1) of the present disclosure has a string-shaped guide member (300) made of an elastic material.

[0080] Specifically, the guide member (300) includes a first guide member (301) provided in the lower region (LF) of the first non-expanded region (NE1) and connecting the first and second partial expansion parts (PEI, PE2), and a second guide member (302) provided in the lower region (LF) of the second non-expanded region (NE2) and connecting the first and third partial expansion parts (PEI, PE3).

[0081] The first guide member (301) is provided in the lower region (LF) of the first non-expanded region (NE1), thereby being provided in the first incision portion (IP1). One end of the first guide member (301) is connected to the lower end of the edge region (EF) that surrounds the first partial expansion portion (PE1) from the outside, and the other end is connected to the lower end of the edge region (EF) that surrounds the second partial expansion portion (PE2) from the outside. More specifically, the first guide member (301) has one end connected to the lower end of the outer edge region (EF) of the first partial expansion portion (PE1) on the side having the 1-1 incision line (C1-1), and the other end opposite to the one end is connected to the lower end of the outer edge region (EF) of the second partial expansion portion (PE2) on the side having the 2-1 incision line (C2-1).

[0082] The first guide member (301) is provided in the first non-expandable region (NE1) and can have the function of integrally connecting the lower ends of the first and second partial expansion parts (PEI, PE2) using elastic force. When the expansion part (E1-1) of the first embodiment is expanded, the first guide member (301) can be formed to be folded so that the distance between the lower ends of the first and second partial expansion parts (PEI, PE2) becomes closer using elastic restoring force.

[0083] In other words, when the expansion portion (E1-1) of the first embodiment expands, the first guide member (301) can reduce the width direction (±x direction) dimension of the lower region (LF) of the first non-expanded region (NE1) through elastic restoring force and can fold the lower portions of the first and second partial expansion portions (PEI, PE2) in the direction (-z direction) in contact with the body part.

[0084] Accordingly, when the expansion portion (E1-1) of the first embodiment expands, the lower portions of the first and second expansion portions (PEI, PE2) are guided to be rounded in the direction (-z direction) in which they come into contact with the body part while being compressed by the first guide member (301). Through this, the human body protection device (1) of the present disclosure can prevent the problem that the expansion portion (E1-1) of the first embodiment expands when the expansion portion (E1-1) of the first embodiment expands and lifts toward the upper body, thereby exposing the body part (outer side of the buttocks and thighs) and failing to properly cover the body part.

[0085] The human body protection device (1) of the present disclosure guides the lower portions of the first and second partial expansion portions (PE1) to be rounded in the direction of contact with the body part (-z direction) by contracting them through the elastic restoring force of the guide member (specifically, the first guide member (301)) when the first and second partial expansion portions (PE1) are inflated. As a result, the first partial expansion portion (PE1) is inflated while making relatively close contact with the buttocks while minimizing the distance from the buttocks in the thickness direction (±z direction). The second partial expansion portion (PE1) is inflated while making more close contact with the outer line of the thigh while minimizing the distance from the outer side of the thigh in the thickness direction (±z direction). As a result, the human body protection device (1) of the present disclosure can more effectively wrap and protect the buttocks and one outer side of the thigh through the first and second partial expansion portions (PE1).

[0086] The second guide member (302) is provided in the second non-expanded region (NE2) and performs the same function as the first guide member (301). Specifically, the second guide member (302) is coupled to the lower part of the outer edge area (EF) of the first partial expansion part (PE1) having a first-second cut line (C1-2) at one end, and the other end opposite to the first end is coupled to the lower part of the outer edge area (EF) of the third partial expansion part (PE3) having a third-first cut line (C3-1). Through this, the second guide member (302) can perform the function of integrally connecting the lower parts of the first and third partial expansion parts (PEI, PE3). The second guide member (302) can be configured to be bent so that the distance between the lower ends of the first and third part expansion parts (PEI, PE3) becomes closer through elastic restoring force when the expansion part (E1-1) of the first embodiment expands.

[0087] The second guide member (302) can reduce the width direction (±arc direction) dimension of the lower region (LF) of the second non-expanded region (NE1) through elastic restoring force when the expansion portion (E1-1) of the first embodiment expands, and can fold the lower portion of the first and second partial expansion portions (PEI, PE2) in the direction (-z direction) in contact with the body part.

[0088] The human body protection device (1) of the present disclosure guides the lower portions of the first and third partial expansion parts (PEI, PE3) to be rounded in the direction of contact with the body part (-z direction) by folding them through the second guide member (302). As a result, the human body protection device (1) of the present disclosure can effectively wrap and protect the buttocks and the outer side of the other thigh.

[0089] The human body protection device (1) of the present disclosure may be provided with a fastening portion (400) in the upper region (UF) of the non-expandable region (NE). The fastening portion (400) may be provided by integrally joining the overlapping portions in which the first-first cut line (C-1) and the second-first cut line (C2-1) overlap with each other using a thread that implements a sewing method. In this case, the fastening portion (400) is a sewing line formed in the overlapping portion. Alternatively, the fastening portion (400) may be provided by integrally joining the first-first cut line (C-1) and the second-first cut line (C2-1) with a member made of the same elastic material as the guide member (300). In this case, the fastening portion (400) is a member made of an elastic material.

[0090] The human body protection device (1) of the present disclosure can integrally connect the overlapping portion formed by overlapping the first-first incision line (C1-1) and the second-first incision line (C2-1). The overlapping portion can be entirely connected by a sewing method, or at least a portion thereof can be connected. The human body protection device (1) of the present disclosure can be provided with a fastening portion (400) in the upper region (UF) of the non-expandable region (specifically, the first non-expandable region (NE1)) by connecting the overlapping portion formed by overlapping the first-first incision line (C1-1) and the second-first incision line (C2-1) by a sewing method, or by connecting it through a member made of an elastic material. The fastening portion (400) provided in the first non-expandable region (NE1) is the first fastening portion (401).

[0091] The human body protection device (1) of the present disclosure is provided with a second fastening portion (402) in the upper region (UF) of the second non-expandable region (NE2) by integrally combining the overlapping portion formed by overlapping the first-second cutting line (C1-2) and the third-first cutting line (C3-1). The second fastening portion (402) may be provided by sewing the overlapping portion formed by overlapping the first-second cutting line (C1-2) and the third-first cutting line (C3-1), and may also be provided with a member made of an elastic material.

[0092] The fastening portion (400) including the first and second fastening portions (401, 402) may be provided in an overlapping portion where the first-first cutting line (C1-1) and the second-first cutting line (C2-1) overlap, and an overlapping portion where the first-second cutting line (C1-2) and the third-first cutting line (C3-1) overlap, such that the overlapping portion faces in the opposite direction (+z direction) to the direction in which the body part is in contact (-z direction). Accordingly, the fastening portion (400) is provided in a form in which it is exposed in the opposite direction (+z direction) to the direction in which the body part is in contact (-z direction). In this case, the fastening portion (400) is preferably provided by a sewing method.

[0093] The human body protection device (1) of the present disclosure can more easily form a frame for forming a three-dimensional space that accommodates the buttocks and both thighs when the expansion part (E1-1) of the first embodiment is expanded through the fastening part (400).

[0094] Specifically, the human body protection device (1) of the present disclosure can form a bend in the non-expanded region (NE) between the first to third expanded portions (PEI, PE2, PE3) through the first fastening portion (401) and the second fastening portion (402) when the expanded portion (E1-1) of the first embodiment is expanded.

[0095] More specifically, the human body protection device (1) of the present disclosure can be coupled in a form in which the second part expansion part (PE2) is bent at a predetermined angle toward the direction (-z direction) in which the body part is in contact with the second part expansion part (PE1) through the first fastening part (401). In addition, the human body protection device (1) of the present disclosure can be coupled in a form in which the third part expansion part (PE3) is bent at a predetermined angle toward the direction (-z direction) in which the body part is in contact with the third part expansion part (PE1) through the second fastening part (402).

[0096] Accordingly, the expansion portion (E1-1) of the first embodiment can primarily form a curved three-dimensional space that accommodates the outer side of one thigh, the buttocks, and the outer side of the other thigh in the pre-inflation state. When the expansion portion (E1-1) of the first embodiment is inflated, the second and third partial expansion portions (PE2, PE3) can be inflated by the fastening portion (400) to a state where the second and third partial expansion portions (PE2, PE3) are curved at a predetermined angle in the direction (-z direction) in which the first partial expansion portion (PE1) is in contact with the body part. As a result, the three-dimensional space that accommodates the buttocks and both thighs can be more easily formed.

[0097] The human body protection device (1) of the present disclosure has a fastening portion (400) in an upper region (UF) of a non-expandable region (NE), and a guide member (300) in a lower region (LF). Specifically, a first guide member (301) is provided at a lower portion of the first fastening portion (401), and a second guide member (302) is provided at a lower portion of the second fastening portion (402).

[0098] The human body protection device (1) of the present disclosure is provided with a guide member (300) at the lower portion of the fastening member (400), so that when the expansion member (E1-1) of the first embodiment is expanded, the lower portion of the frame for forming a three-dimensional space for accommodating the buttocks and both thighs is rounded and bent in the direction (-Z direction) in which it comes into contact with the body part. The frame for forming the three-dimensional space is formed through the first to fourth partial expansion members (PEI, PE2, PE3, PE4). The guide member (300) is provided in the non-expanded region (NE), so that when the expansion member (E1-1) of the first embodiment is expanded, the lower portions of the first to third partial expansion members (PEI, PE2, PE3) are rounded in the direction (-z direction) in which they come into contact with the body part. Accordingly, the human body protection device (1) of the present disclosure can prevent the problem that, when the expansion part (E1-1) of the first embodiment expands, the expansion part (E1-1) of the first embodiment expands while being lifted in the upward direction (+y direction), thereby failing to properly protect the body part.

[0099] The expansion portion (E1-1) of the first embodiment has a plurality of guide portions (GP) having a length in the longitudinal direction (±y direction). Specifically, the expansion portion (E) has a plurality of guide portions (GP) within a plurality of partial expansion portions (PE). The plurality of guide portions (GP) guide the movement of an expansion material (air and fluid) injected into an expansion region (PS) of the expansion portion (E). Specifically, the expansion material is guided to move within the expansion region (PS) along the shapes of the plurality of guide portions (GP) at a portion where the plurality of guide portions (GP) are formed, and is uniformly distributed.

[0100] The plurality of guide portions (GP) are formed by thermally fusing the first and second fabrics. Alternatively, the plurality of guide portions (GP) may be formed by sewing the first and second fabrics. Accordingly, the portion where the plurality of guide portions (GP) are formed does not have a space where the first and second fabrics are integrated. The expansion portion (E) has a space formed by debonding the first and second fabrics around the plurality of guide portions (GP). The expansion material is uniformly distributed along the plurality of guide portions (GP) and into the space existing around the plurality of guide portions (GP).

[0101] FIG. 4a is a plan view of a human body protection device (1) having an expansion portion (hereinafter, referred to as expansion portion (E1-2) of the first embodiment) according to a preferred embodiment 1-2 of the present disclosure, and FIG. 4b is a side view of a wearing example of the human body protection device (1) including the expansion portion (E1-2) of the first embodiment. In FIG. 4b, the expansion portion (E1-2) according to the first embodiment is schematically illustrated.

[0102] In the description of the human body protection device (1) having the expansion part (E1-2) of the first embodiment with reference to FIGS. 4a and 4b, the description will be centered on the characteristic components compared to the human body protection device (1) having the expansion part (E1-1) of the first embodiment, and the description of the components that are the same or similar to the human body protection device (1) having the expansion part (E1-1) of the first embodiment will be omitted as much as possible.

[0103] Referring to FIGS. 4a and 4b, the expansion member (E1-2) of the first-second embodiment has a first guide member (301) between the first and second partial expansion members (PEI, PE2), and a second guide member (302) between the first and third partial expansion members (PEI, PE3). The arrows shown around the first partial expansion member (PE1) in FIG. 4b indicate the direction in which the lower end of the first partial expansion member (PE1) is guided to be rounded by the first guide member (301).

[0104] The expansion member (E1-2) of the first embodiment preferably has a guide member (300) made of a thread.

[0105] The first guide member (301) has one end connected to the outer edge area (EF) of the first partial expansion portion (PE1) on the side having the first-first cutting line (C1-1), and the other end connected to the front free end (hereinafter referred to as the front free end (FP2) of the second partial expansion portion (PE2)) of the outer edge area (EF) of the second partial expansion portion (PE2). The front free end (FP2) of the second partial expansion portion (PE2) is a portion that is included in the edge area (EF) that surrounds the second partial expansion portion (PE2) from the outside, and is located on the side opposite to the side having the second-first cutting line (C2-1). Accordingly, the front free end (FP2) of the second partial expansion portion (PE2) is positioned while facing forward (-z direction) based on the thickness direction (±z direction) when the human body protection device (1) of the present disclosure is worn.

[0106] The expansion portion (E1-2) of the first embodiment can be provided with the first guide member (301) so that the position connecting the other end of the first guide member (301) is higher than the position connecting one end of the first guide member (301) in the longitudinal direction (±y direction).

[0107] Specifically, one end of the first guide member (301) is provided below the 1-1 incision line (C1-1) and is connected to the lower end of the outer edge area (EF) of the first partial expansion portion (PE1). The other end of the first guide member (301) is connected to the front free end (FP2) of the second partial expansion portion (PE2), and is connected at a position higher than the height at which one end of the first guide member (301) is connected based on the longitudinal direction (±y direction). Accordingly, referring to FIG. 3, the first guide member (301) is provided in the expansion portion (E1-2) of the 1-2 embodiment in a form that slopes downward from the front free end (FP2) of the second partial expansion portion (PE2) to the outer edge area (EF) of the first partial expansion portion (PE1). Through this, the first guide member (301) can guide the lower part of the first partial expansion part (PE1) on the side having the first-first incision line (C1-1) to be rounded in the direction of contact with the body part (-z direction, forward) while pulling it in the direction of contact with the body part when the expansion part (E1-2) of the first-second embodiment is expanded.

[0108] In contrast, the expansion member (E1-2) of the first embodiment (1-2) may be provided with the first guide member (301) so that the heights of the position connecting one end of the first guide member (301) and the position connecting the other end are the same based on the longitudinal direction (±y direction).

[0109] The second guide member (302) has one end connected to the outer edge area (EF) of the first partial expansion portion (PE1) on the side having the first-second cut line (C1-1), and the other end connected to the front free end (hereinafter referred to as the front free end (FP3) of the third partial expansion portion (PE3)) of the outer edge area (EF) of the third partial expansion portion (PE3). The front free end (FP3) of the third partial expansion portion (PE3) is a portion that is included in the edge area (EF) that surrounds the third partial expansion portion (PE3) from the outside, and is located on the side opposite to the side having the third-first cut line (C3-1). Accordingly, the front free end (FP3) of the third partial expansion portion (PE3) is positioned while facing forward (-z direction) based on the thickness direction (±z direction) when the human body protection device (1) of the present disclosure is worn. The front free end (FP3) of the third part expansion part (PE3) is positioned symmetrically with respect to the front free end (FP2) of the second part expansion part (PE2) in the width direction (±x direction).

[0110] The second guide member (302) can guide the lower part of the first partial expansion part (PE1) on the side having the first-second cutting line (C1-2) to be rounded in the direction of contact with the body part (-z direction, forward) while pulling it in the direction of contact with the body part when the expansion part (E1-2) of the first-second embodiment is expanded.

[0111] Referring to FIG. 4b, the expansion part (E1-2) of the first-second embodiment, when inflated, fixes the other end of the first guide member (301) coupled to the front free end (FP2) of the second partial expansion part (PE2) and pulls one end of the first guide member (301) coupled to the lower end of the first partial expansion part (PE1) in the direction in which the front free end (FP2) of the second partial expansion part (PE2) is positioned (in the direction in which it contacts the body part (+z direction).

[0112] More specifically, when the expansion portion (E1-2) of the first embodiment is expanded, one end of the first guide member (301) is connected to the lower end of the outer edge area (EF) of the first partial expansion portion (PE1) on the side having the first-first cutting line (C1-1) and is pulled in the direction (+z direction) in contact with the body part based on the fixing position. Through this, the expansion portion (E1-2) of the first embodiment can be expanded while rounding the lower end of the first partial expansion portion (PE1) on the side having the first-first cutting line (C1-1) in the direction (+z direction) in contact with the body part when expanded.

[0113] In addition, when the expansion part (E1-2) of the first embodiment is expanded, the other end of the second guide member (302) coupled to the front free end (FP3) of the third part expansion part (PE3) is fixed in a position, and one end of the second guide member (302) connected to the lower end of the first part expansion part (PE1) is pulled in the direction (+z direction) in which the front free end (FP3) of the third part expansion part (PE3) is located (the direction in which the body part is in contact). More specifically, when the expansion part (E1-2) of the first embodiment is expanded, one end of the second guide member (302) is connected to the lower end of the outer edge area (EF) of the first part expansion part (PE 1) on the side having the 1-2 incision line (C1-1) and is pulled in the direction in which the body part is in contact (+z direction) based on the fixed position. Through this, when the expansion part (E1-2) of the first embodiment is expanded, The lower part of the first expansion part (PE1) on the side where the first-second incision line (C1-2) is provided can be expanded while being rounded in the direction (+z direction) that contacts the body part.

[0114] Due to this, the expansion part (E1-2) of the first and second embodiments can prevent the problem of the partial expansion part (PE) being lifted toward the upper body when inflated, thereby exposing the buttocks and not properly covering them.

[0115] In addition, the expansion portion (E1-2) of the first embodiment can be expanded by making closer contact with the buttocks and reducing the distance between the first expansion portion (PE1) and the buttocks through the first and second guide members (301, 302) when inflated. As a result, the human body protection device (1) equipped with the expansion portion (E1-2) of the first embodiment can protect the buttocks more effectively.

[0116] The human body protection device (1) of the present disclosure having an expansion portion (E1-2) of the first embodiment connects the first and second partial expansion portions (PE1, PE2) by a first fastening portion (401) provided in the first non-expandable area (NE1), and connects the first and third partial expansion portions (PEI, PE3) by a second fastening portion (402) provided in the second non-expandable area (NE2).

[0117] FIG. 5 is a plan view of an expansion member according to a preferred embodiment 1-3 of the present disclosure (hereinafter referred to as an expansion member (E1-3) of the preferred embodiment 1-3).

[0118] In the description of the human body protection device (1) having the expansion part (E1-3) of the first embodiment with reference to FIG. 5, the characteristic components will be described in comparison with the human body protection device (1) having the expansion part (E1-1) of the first embodiment, and the description of the components that are the same or similar to the human body protection device (1) having the expansion part (E1-1) of the first embodiment will be omitted as much as possible.

[0119] Referring to FIG. 5, the expansion portion (E1-3) of the first to third embodiment is provided with the first to third partial expansion portions (PEI, PE2, PE3) cut from each other through the first and second incision portions (IP1, IP2), and the first to third partial expansion portions (PEI, PE2, PE3) are each branched through the partial incision portion (PI).

[0120] Specifically, the first partial expansion portion (PE1) is cut through a partial incision portion (PI) and includes a first-first partial expansion portion (PE1-1), a first-second partial expansion portion (PE1-2) provided on one side of the first-first partial expansion portion (PE1-1), and a first-third partial expansion portion (PE1-3) provided on the other side of the first-first partial expansion portion (PE1-1).

[0121] The second partial expansion portion (PE2) is cut through a partial incision portion (PI) and includes a second-first partial expansion portion (PE2-1), a second-second partial expansion portion (PE2-2) provided on one side of the second-first partial expansion portion (PE2-1), and a second-third partial expansion portion (PE2-3) provided on the other side of the second-first partial expansion portion (PE2-1).

[0122] The third partial expansion part (PE3) is cut through a partial incision site (PI) and includes a third-first partial expansion part (PE3-1), a third-second partial expansion part (PE3-2) provided on one side of the third-first partial expansion part (PE3-1), and a third-third partial expansion part (PE3-3) provided on the other side of the third-first partial expansion part (PE3-1).

[0123] The expansion portion (E1-3) of the first to third embodiment connects the partial expansion portions (PE) between adjacent two partial expansion portions (PE) among the plurality of partial expansion portions (PE) constituting each of the first to third partial expansion portions (PEI, PE2, PE3) through a guide member (300). In addition, the guide member (300) guides the lower ends of the plurality of partial expansion portions (PE) constituting each of the first to third partial expansion portions (PEI, PE2, PE3) to be rounded in the direction (-z direction) in which they come into contact with a body part.

[0124] The human body protection device (1) of the present disclosure having the expansion portion (E1-3) of the first to third embodiment preferably has a guide member (300) composed of an elastic material. However, when the guide member (300) performs only a fastening function depending on the position (e.g., upper region, middle region, and lower region) provided based on the longitudinal direction (±y direction) when fastening a plurality of partial expansion portions (PE) constituting each of the first to third partial expansion portions (PEI, PE2, PE3), the guide member (300) may be composed of an elastic material or may be composed of an inelastic material such as thread.

[0125] The plurality of partial expansion parts (PE) constituting each of the first to third partial expansion parts (PEI, PE2, PE3) are connected in the same shape through the guide member (300). In other words, the structure of connecting the plurality of partial expansion parts (PE) constituting each of the first to third partial expansion parts (PEI, PE2, PE3) through the guide member (300) is the same.

[0126] Referring to FIG. 5, a fastening and joining structure through a guide member (300) of a plurality of partial expansion parts (PE) constituting the first partial expansion part (PE1) is described.

[0127] The human body protection device (1) of the present disclosure has a first guide member (301) between the first-first part expansion part (PE1-1) and the first-second part expansion part (PE1-2), and a second guide member (302) between the first-first part expansion part (PE1-1) and the first-third part expansion part (PE1-3).

[0128] The first guide member (301) may be provided in multiple numbers in the upper region, the middle region, and the lower region, respectively, based on the longitudinal direction (±y direction) of the first part cut portion (PI1) provided between the first-first part expansion portion (PE1-1) and the first-second part expansion portion (PE1-2). The number of first guide members (301) provided in the first part cut portion (PI1) is not limited thereto.

[0129] The first guide member (301a) provided in the upper region of the first partial incision portion (PI1) has one end connected to the upper portion of one side edge region (EF) of the first-first partial expansion portion (PE1-1) located on the first partial incision portion (PI1) side, and the other end connected to the upper portion of one side edge region (EF) of the first-second partial expansion portion (PE1-2) located on the first partial incision portion (PI1) side. Through this, the first-first and 1-2 partial expansion portions (PE1-1, PE1-2) are partially (upper) fastened.

[0130] The first guide member (301b) provided in the middle region of the first partial incision portion (PI1) has one end connected to the middle region of one edge region (EF) of the first-first partial expansion portion (PE1-1) located on the first partial incision portion (PI1) side, and the other end connected to the middle region of one edge region (EF) of the first-second partial expansion portion (PE1-2) located on the first partial incision portion (PI1) side. Through this, the middle portions of the first-first and 1-2 partial expansion portions (PE1-1, PE1-2) are fastened.

[0131] The first guide members (301a, 301b) provided in the upper and middle regions of the first partial incision portion (PI1) provide a function of fastening the upper and middle regions of the first-1, 1-2 partial expansion portions (PE1-1, PE1-2). Accordingly, the first guide members (301a, 301b) provided in the upper and middle regions of the first partial incision portion (PI1) may be made of an elastic material or an inelastic material such as thread.

[0132] The first guide member (301c) provided in the lower region of the first partial incision portion (PI1) has one end connected to the lower end of one edge region (EF) of the first-first partial expansion portion (PE1-1) located on the first partial incision portion (PI1) side, and the other end connected to the lower end of one edge region (EF) of the first-second partial expansion portion (PE1-2) located on the first partial incision portion (PI1) side. Through this, the lower portions of the first-first and 1-second partial expansion portions (PE1-1, PE1-2) are connected. The first guide member (301c) provided in the lower region of the first partial incision portion (PI1) is made of an elastic material.

[0133] Accordingly, the first guide member (301c) provided in the lower region of the first partial incision portion (PI1) connects the lower portions of the first-first partial expansion portion (PE1-1) and the first-second partial expansion portion (PE1-2). In addition, the first guide member (301c) provided in the lower region of the first partial incision portion (PI1) guides the lower portions of the first-first partial expansion portion (PE1-1) and the first-second partial expansion portion (PE1-2) to be rounded in the direction (-z direction) in contact with the body part through elastic restoring force when the expansion portion (E1-3) of the first-third embodiment is expanded.

[0134] Referring to FIG. 5, before the expansion of the expansion portion (E1-3) of the first-third embodiment, the first guide member (301c) provided in the lower region of the first partial cut portion (PI1) is maintained in a state of being connected between the first-1 and 1-2 partial expansion portions (PE1-1, PE1-2) while being extended by elastic force.

[0135] In contrast, when the expansion portion (E1-3) of the first-third embodiment expands, the first guide member (301c) provided in the lower region of the first partial incision portion (PI1) gradually reduces the distance between the lower ends of the first-first, 1-2 partial expansion portions (PE1-1, PE1-2) as it shrinks due to elastic restoring force. Accordingly, the first guide member (301c) provided in the lower region of the first partial incision portion (PI1) guides the lower ends of the first-first, 1-2 partial expansion portions (PE1-1, PE1-2) to be rounded in the direction of contact with the body part (-z direction) while causing them to contract.

[0136] Meanwhile, when the first guide members (301a, 301b, 301c) provided in the upper region, middle region, and lower region of the first partial incision site (PI1) are all composed of an elastic material, the elasticity of the first guide member (301c) provided in the lower region is greater than that of the first guide members (301a, 301b) provided in the upper region and middle region.

[0137] In addition, in the expansion completion state of the expansion portion (E1-3) of the first-third embodiment, the width direction (±arc direction) dimension of the first guide member (301c) provided in the lower region of the first partial cut portion (PI1) is smaller than the dimensions of the first guide members (301a, 301b) provided in the upper region and middle region of the first partial cut portion (PI1).

[0138] The human body protection device (1) of the present disclosure is provided with a second guide member (302) in a second part incision portion (PI2) provided between a first-first part expansion portion (PE1-1) and a first-third part expansion portion (PE1-3). A plurality of second guide members (302) are provided in the upper region, the middle region, and the lower region of the second part incision portion (PI2). The number of second guide members (302) is not limited thereto.

[0139] The second guide member (302) provided in the second partial incision portion (PI2) connects one end to the other edge area (EF) of the first-first partial expansion portion (PE1-1) located on the second partial incision portion (PI2) side, and the other end to one edge area (EF) of the first-third partial expansion portion (PE1-3) located on the second partial incision portion (PI2) side. Through this, the second guide member (302) connects the first-first partial expansion portion (PE1-1) and the first-third partial expansion portion (PE1-3).

[0140] The human body protection device (1) of the present disclosure may comprise a second guide member (302c) provided in a lower region of a second partial incision site (PI2) made of an elastic material. The second guide member (302) of an elastic material provided in a lower region (LF) of the second partial incision site (PI2) provides a function of fastening the first-1, first-3 partial expansion parts (PE1-1, PE1-3). In addition, the second guide member (302c) of the lower region (LF) of the second partial incision site (PI2) provides a function of guiding the lower portions of the first-1, first-3 partial expansion parts (PE1-1, PE1-3) to be rounded in a direction (-z direction) in contact with a body part.

[0141] Meanwhile, the second guide members (302a, 302b) provided in the upper region, middle region, and lower region of the second partial incision site (PI2) may all be composed of an elastic material. In this case, the second guide member (302c) provided in the lower region has greater elasticity than the second guide members (302a, 302b) provided in the upper region and middle region. In addition, the second guide member (302c) provided in the lower region has a smaller dimension in the width direction (±x direction) than the second guide members (302a, 302b) provided in the upper region and middle region when the expansion portion (E1-3) of the first-third embodiment is in an expanded state.

[0142] The 2-1 to 2-3 partial expansion portions (PE2-1, PE2-2, PE2-3) constituting the 2nd partial expansion portion (PE2) and the 3-1 to 3-3 partial expansion portions (PE3-1, PE3-2, PE3-3) constituting the 3rd partial expansion portion (PE3) include the 1st and 2nd partial incision portions (PI1, PI2) by the incision shape. The human body protection device (1) of the present disclosure is provided with a first guide member (301) and a second guide member (302) in the first and second partial incision portions (PI1, PI2) provided between the 2-1 to 2-3 partial expansion portions (PE2-1, PE2-2, PE2-3) and in the first and second partial incision portions (PI1, PI2) provided between the 3-1 to 3-3 partial expansion portions (PE3-1, PE3-2, PE3-3), respectively. A plurality of first and second guide members (301, 302) may be provided.

[0143] The 2-1 to 2-3 partial expansion parts (PE2-1, PE2-2, PE2-3) and the 3-1 to 3-3 partial expansion parts (PE3-1, PE3-2, PE3-3) are fastened and joined in the same manner as the 1-1 to 1-3 partial expansion parts (PE1-1, PE1-2, PE1-3) are fastened and joined through the 1st and 2nd guide members (301, 302).

[0144] The human body protection device (1) of the present disclosure comprises first and second guide members (301, 302) made of an elastic material in the lower regions of the first and second partial incision portions (PI1, PI2) provided in the 2-1 to 2-3 partial expansion portions (PE2-1, PE2-2, PE2-3) and the first and second partial incision portions (PI1, PI2) provided in the 3-1 to 3-3 partial expansion portions (PE3-1, PE3-2, PE3-3).

[0145] Through this, the first and second guide members (301, 302) provide a function of guiding the lower portions of the second-1 to second-3 part expansion portions (PE2-1, PE2-2, PE2-3) and the third-1 to third-3 part expansion portions (PE3-1, PE3-2, PE3-3) to be rounded in the direction of contact with the body part.

[0146] The expansion portion (E1-3) of the first-third embodiment may have the longitudinal (±y direction) dimensions of the first and second incision portions (IP1, IP2) larger than the dimensions of the first and second partial incision portions (PI1, PI2). This is to more easily provide a frame that forms a three-dimensional space for accommodating body parts through the first to third partial expansion portions (PE1, PE2, PE3) when the expansion portion (E1-3) of the first-third embodiment is expanded.

[0147] The expansion portion (E1-3) of the first embodiment can be provided with a fourth partial expansion portion (PE4) that is continuously provided in the width direction (±x direction) on the upper portions of the first to third partial expansion portions (PEI, PE2, PE3) in a segmented form by providing the longitudinal (±y direction) dimensions of the first and second incision portions (IP1, IP2) to be larger than the dimensions of the first and second partial incision portions (PI1, PI2). The expansion portion (E1-3) of the first embodiment is provided in a form in which a section corresponding to the second partial expansion portion (PE2) and a section corresponding to the first partial expansion portion (PE1) are segmented by the first incision portion (IP1). In addition, the expansion portion (E1-3) of the first-third embodiment is segmented between a section corresponding to the third partial expansion portion (PE3) and a section corresponding to the first partial expansion portion (PE1) by the second incision portion (IP2).

[0148] The expansion portion (E1-3) of the first-third embodiment is provided with a fourth expansion portion (PE4) segmented by the first and second incision portions (IP1, IP2), thereby minimizing lifting caused by the gap between the fourth expansion portion and the pelvic region during expansion. In addition, the problem of the first expansion portion (PE1) being lifted in the upper body direction can be more effectively prevented.

[0149] Specifically, the human body protection device (1) of the present disclosure has a fastening portion (400) at the first and second incision portions (IP1, IP2) by fastening the first and second incision portions (IP1, IP2) with an inelastic material such as thread. The human body protection device (1) of the present disclosure has a first fastening portion (401) at the first incision portion (IP1) and a second fastening portion (402) at the second incision portion (IP2).

[0150] More specifically, the human body protection device (1) of the present disclosure combines an overlapping portion (hereinafter referred to as a first overlapping portion) in which an outer edge area (EF) of a first partial expansion portion (PE1) located on the side of a first incision portion (IP1) and an outer edge area (EF) of a second partial expansion portion (PE2) located on the side of the first incision portion (IP1) overlap each other through a sewing method. The first overlapping portion can be entirely combined by a first fastening portion (401). Accordingly, the first fastening portion (401) is provided at the first incision portion (IP1). The first incision portion (IP1) can be entirely sewn and removed by the first fastening portion (401).

[0151] Alternatively, the human body protection device (1) of the present disclosure may have a first fastening portion (401) provided on at least a portion of the first overlapping portion by coupling at least a portion of the first overlapping portion and leaving the remaining portion uncoupled.

[0152] The human body protection device (1) of the present disclosure may be provided with a first fastening portion (401) such that, when forming a first overlapping portion, the outer edge area (EF) of the first partial expansion portion (PE1) located on the side of the first incision portion (IP1) constituting the first overlapping portion and the outer edge area (EF) of the second partial expansion portion (PE2) located on the side of the first incision portion (IP1) are positioned in the opposite direction (+z direction) to the direction in which the first overlapping portion is in contact with the body part (-z direction). Accordingly, the first overlapping portion provided with the first fastening portion (401) is provided in a state in which it protrudes in the opposite direction (+z direction) to the direction in which the first overlapping portion is in contact with the body part (-z direction). This is to prevent contact between the first overlapping portion and the body part when the expansion portion (E1-3) of the first-3 embodiment is expanded, and to prevent expansion interference due to contact between the first overlapping portion and the body part.

[0153] The human body protection device (1) of the present disclosure has a first overlapping portion positioned in the opposite direction (+z direction) to the direction (-z direction) in which the expansion portion (E1-3) of the first embodiment contacts the body part through the first fastening portion (401). As a result, the expansion portion (E1-3) of the first embodiment has a bend of a predetermined angle between the first partial expansion portion (PE1) and the second partial expansion portion (PE2) in a state before expansion. More specifically, the second partial expansion portion (PE2) is positioned forward (-z direction) by a predetermined amount relative to the first partial expansion portion (PE1) in the thickness direction (±z direction). As a result, the expansion portion (E1-3) of the first embodiment can primarily form a frame that forms a three-dimensional space for accommodating a body part in a state before expansion.

[0154] The expansion portion (E1-3) of the first embodiment of the present invention has a fourth partial expansion portion (PE4) having a curve in a segmented section formed between a section corresponding to the first partial expansion portion (PE1) and a section corresponding to the second partial expansion portion (PE2) by a first overlapping section formed at the first incision section (IP1). Accordingly, when the expansion portion (E1-3) of the first embodiment of the present invention is expanded, the fourth partial expansion portion (PE4) can expand while bringing a section (region) corresponding to the central pelvic region existing in the upper part of the buttocks and a section (region) corresponding to one side pelvic region existing in the upper part of one side thigh into closer contact with the central pelvic region and the one side pelvic region.

[0155] The fourth partial expansion portion (PE4) has a curve in the segmented section formed between the section corresponding to the first partial expansion portion (PE1) and the section corresponding to the third partial expansion portion (PE2) by the second overlapping section formed in the second incision section (IP2). Accordingly, when the expansion portion (E1-3) of the first-third embodiment is expanded, the fourth partial expansion portion (PE4) can expand while bringing the section (region) corresponding to the central pelvic region existing in the upper part of the buttocks and the section (region) corresponding to the other pelvic region existing in the upper part of the other thigh closer to the central pelvic region and the other pelvic region.

[0156] Through this, the human body protection device (1) of the present disclosure can minimize lifting between the pelvic region and the fourth partial expansion portion (PE4) existing in the buttocks and upper thighs on both sides when the expansion portion (E1-3) of the first to third embodiments is expanded. Furthermore, a structure can be formed that more effectively prevents the problem of lifting in the upper body direction when the first to third partial expansion portions (PEI, PE2, PE3) expanded from the lower portion of the fourth partial expansion portion (PE4) are expanded.

[0157] The human body protection device (1) of the present disclosure has a second overlapping portion at the second incision portion (IP2) by overlapping the outer edge area (EF) of the first partial expansion portion (PE1) located on the second incision portion (IP2) side and the outer edge area (EF) of the third partial expansion portion (PE2) located on the second incision portion (IP2). A second fastening portion (402) is provided at the second overlapping portion. The second overlapping portion is provided to protrude in the opposite direction (+z direction) to the direction (-z direction) in which it contacts the body portion, similar to the first overlapping portion. Accordingly, the second overlapping portion and the body portion do not come into contact.

[0158] The expansion portion (E1-3) of the first embodiment has a predetermined angle of curvature between the first partial expansion portion (PE1) and the third partial expansion portion (PE2) in a pre-inflation state by the second overlapping portion having the second fastening portion (402). More specifically, the third partial expansion portion (PE3) is provided in a form in which it is positioned a predetermined amount forward (-z direction) of the first partial expansion portion (PE1) based on the thickness direction (±z direction). As a result, the expansion portion (E1-3) of the first embodiment can primarily form a frame that forms a three-dimensional space for accommodating a body part in a pre-inflation state.

[0159] Meanwhile, the fastening portion (400) including the first and second fastening portions (401, 402) may be made of the same elastic material as the guide member (300) provided in the partial cut portion (PI).

[0160] FIG. 6a is a plan view of a human body protection device (1) including an expansion part (hereinafter, referred to as an expansion part (E2) of the second embodiment) according to a preferred second embodiment of the present disclosure in a state before expansion, FIG. 6b is a side view of a wearing example of a human body protection device including an expansion part (E2) of the second embodiment in a state before expansion, FIG. 6c is a side view of the expansion part (E2) of the second embodiment in a state during expansion in a wearing state, and FIG. 6d is a side view of the expansion part (E2) of the second embodiment in a state after expansion is completed in a wearing state.

[0161] In the description of the human body protection device (1) having the expansion part (E2) of the second embodiment with reference to FIGS. 6a to 6d, the description will focus on the characteristic components compared to the human body protection device (1) having the expansion part (E1-1) of the first embodiment, and the description of the components that are the same or similar to the human body protection device (1) having the expansion part (E1-1) of the first embodiment will be omitted as much as possible.

[0162] Referring to FIGS. 6a to 6d, the human body protection device (1) of the present disclosure having an expansion portion (E2) of the second embodiment includes a guide member (300) having one end coupled to at least one of the wearing portion (100) and the expansion portion (E2) of the second embodiment and the other end coupled to the remaining one.

[0163] Specifically, the human body protection device (1) of the present disclosure having the expansion portion (E2) of the second embodiment has first and second guide members (301, 302). The first and second guide members (301, 302) may be made of an elastic material or may be made of yarn. The human body protection device (1) of the present disclosure has first and second guide members (301, 302) made of yarn in the expansion portion (E2) of the second embodiment. The first and second guide members (301, 302) are provided to be longer than the length of the expansion portion (E2) of the second embodiment in the longitudinal direction (±y direction). Accordingly, the first and second guide members (301, 302) are provided inside the wearable part (100) by folding them so as to overlap each other in the same manner as the expansion portion (E2) of the second embodiment is folded so as to overlap each other and provided inside the wearable part (100).

[0164] The first guide member (301) is connected at one end to the lower part of the first-first incision line (C1-1) and is joined to the expansion part (E2) of the second embodiment, and the other end is joined to the widthwise sewing part (WP) and is joined to the wearing part (100).

[0165] More specifically, one end of the first guide member (301) is joined to the lower inner surface of the outer edge area (EF) of the first partial expansion portion (PE1) having the first-first incision line (C1-1). The other end of the first guide member (301) is joined to the inner surface of the widthwise sewing portion (WP) at a position corresponding to the first-first joining member (B1-1) in the area of ​​the widthwise sewing portion (WP). Accordingly, the first guide member (301) is positioned in the direction (-z direction) in contact with the body part and is provided in an unexposed form.

[0166] The second guide member (302) is provided symmetrically with the first guide member (301) in the width direction (±x direction) based on the vertical center line of the expansion portion (E2) of the second embodiment. Accordingly, one end of the second guide member (302) is coupled to the lower inner surface of the outer edge area (EF) of the first partial expansion portion (PE1) having the 1-2 cut line (C1-2). The other end of the second guide member (302) is coupled to the inner surface of the widthwise sewing portion (WP) at a position corresponding to the 1-6 joining member (B1-6) in the area of ​​the widthwise sewing portion (WP).

[0167] The positions where one end and the other end of the first and second guide members (301, 302) are joined are not limited thereto. The first and second guide members (301, 302) can be joined to the wearing member (100) and the expanding member (E2) of the second embodiment in such a manner that one end is joined to the wearing member (100) and the other end is joined to the expanding member (E2) of the second embodiment, preferably to the lower end of the expanding member (E2).

[0168] The human body protection device (1) of the present disclosure having an expansion portion (E2) of the second embodiment expands by guiding the first expansion portion (PE1) that surrounds the buttocks to be rounded in the direction (-z direction) in contact with the body part (buttocks) through the first and second guide members (301, 302) when the expansion portion (E2) of the second embodiment expands.

[0169] Referring to Fig. 6b, the first guide member (301) is connected at one end to the wearing part (100) and at the other end to the lower end of the first partial expansion part (PE1).

[0170] Referring to Fig. 6c, the first guide member (301) is fixed at one end connected to the wearing part (100), and expands from the pelvic side toward the buttocks side along the expansion of the expansion part (E2) of the second embodiment. At this time, since the first partial expansion part (PE1) is connected at the lower end to the first guide member (301), it expands and expands in the outer direction of the buttocks (-z direction) based on the widthwise thickness direction (±z direction) without increasing the gap distance between the lower end and the buttocks. The arrows shown around the first partial expansion part (PE1) in Fig. 6c indicate the expansion guide direction of the first partial expansion part (PE1) by the first guide member (301) when the expansion part (E2) of the second embodiment expands.

[0171] Referring to FIG. 6d, the expansion part (E2) of the second embodiment completes expansion while connecting the lower end of the first partial expansion part (PE1) to the first guide member (301). The arrows shown around the first partial expansion part (PE1) in FIG. 6d indicate the direction in which the first guide member (301) guides the lower end of the first partial expansion part (PE1) to be rounded in the direction (+z direction) in which it comes into contact with the body part.

[0172] The expansion portion (E2) of the second embodiment protrudes from the wearing portion (100) by the expansion force and expands while spreading toward the buttocks, and completes the expansion in a form in which the buttocks are covered and settled by the other end of the first guide member (301) coupled to the lower end of the first partial expansion portion (PE1).

[0173] The first guide member (301) is provided with a length longer than the length of the expansion portion (E2) of the second embodiment to accommodate a change in length in the thickness direction (±z direction) due to the expansion force of the expansion portion (E2) of the second embodiment. When the expansion of the expansion portion (E2) of the second embodiment is completed, the first guide member (301) guides the lower end of the first partial expansion portion (PE1) in the direction in which it comes into contact with the body part (+z direction) while supporting it at the fixed point with one end coupled to the wearing part (100). As a result, the first partial expansion portion (PE1) is seated on the buttocks so as to wrap around the buttocks, and the lower end is seated in a form in which it is curved in the direction in which it comes into contact with the body part (+z direction) while rounding along the lower line of the buttocks.

[0174] Figures 6b to 6d are side views showing the guiding operation of the first guide member (301) having the first guide member (301). The second guide member (302) guides the first partial expansion part (PE1) to be seated on the buttocks in the same shape as the first guide member (301) in the opposite direction facing the first guide member (301), but so that the lower part of the first partial expansion part (PE1) is seated while being rounded in the direction (+z direction) in which it comes into contact with the body part.

[0175] The human body protection device (1) of the present disclosure having the expansion part (E2) of the second embodiment guides the first partial expansion part (PE1) to be settled on the buttocks in an expanded state when the expansion part (E2) of the second embodiment is completed through the first and second guide members (301, 302). The first partial expansion part (PE1) is settled while being rounded in the direction of contact with the buttocks (+z direction) without being lifted in the outer direction of the buttocks (-z direction) by the first and second guide members (301, 302). Accordingly, the human body protection device (1) of the present disclosure having the expansion part (E2) of the second embodiment can effectively prevent the problem of the first partial expansion part (PE1) being lifted in the upper body direction and not properly protecting the buttocks when the expansion part (E2) of the second embodiment is expanded.

[0176] Again, referring to FIG. 6a, the expansion portion (E2) of the second embodiment may have a first fastening portion (401) at the first incision portion (IP1) and a second fastening portion (402) at the second incision portion (IP2).

[0177] The first fastening part (401) can fasten the first and second partial expansion parts (PEI, PE2), and the second fastening part (402) can fasten the first and third partial expansion parts (PEI, PE3). The expansion part (E2) of the second embodiment can more easily form a frame that forms a three-dimensional space by the first and second fastening parts (401, 402).
