Description

human body protection device

[0001] The present disclosure relates to a human body protection device, and more particularly, to a human body protection device including a sensor module for detecting a user's fall and an inflator for inflating an airbag.

[0002] A fall is an injury or injury resulting from a fall or tripping. Falls are so common that they account for a significant proportion of human deaths. The risk of falls is highest among the elderly, and among occupations such as construction workers, electricians, miners, and painters.

[0003] Various types of wearable protective devices are being used to prevent falls. Typically, wearable devices are worn around the waist to protect the elderly from falls, while devices worn on the upper and / or lower body are used to protect industrial workers and motorcycle riders from falls.

[0004] The protective device primarily uses acceleration and / or angular velocity sensors to detect a fall. Based on the detection signal, the triggering device strikes the gas cartridge, inflating the inflator. Based on this operating method, ongoing research is underway to effectively protect various parts of the human body by varying the shape and number of the protective device's inflatable parts.

[0005] The present disclosure aims to provide the location and number of sensor modules for sensing the posture and motion of a user to clearly detect a fall state.

[0006] The present disclosure aims to provide the location and number of inflators that do not restrict the movement of a user wearing a body protection device during work or daily life.

[0007] An embodiment of the present disclosure may provide a human body protection device including: an inflatable airbag; an inflator that inflates the airbag; a sensor module that senses acceleration data or angular velocity data of a user; and a control module that provides an inflation signal to the inflator based on the acceleration data or angular velocity data.

[0008] In an embodiment of the present disclosure, when the sensor module is composed of only one first sensor unit, the first sensor unit may be placed on the front or back of the user on the user's spine line.

[0009] In an embodiment of the present disclosure, when the sensor module is configured with only one first sensor unit, the first sensor unit may be located within a range of a first predetermined distance from a virtual line connecting the upper and lower sides of the user's shoulders at the rear of the user.

[0010] In an embodiment of the present disclosure, when the sensor module is composed of only two 2-1 sensor units and two 2-2 sensor units, the 2-1 sensor unit and the 2-2 sensor unit may be positioned symmetrically with respect to the user's spine line.

[0011] In an embodiment of the present disclosure, the inflator may be positioned at the front or back of the user, and may be configured as one or more inflators parallel to the spine line at a predetermined distance from the spine line of the user.

[0012] In an embodiment of the present disclosure, the inflator is positioned on the user's thigh and may be composed of one or more inflators.

[0013] In an embodiment of the present disclosure, the inflator is positioned on the user's arm and may be composed of one or more inflators.

[0014] The present disclosure has the effect of providing the location and number of sensor modules that sense the user's posture and motion to clearly detect a fall state.

[0015] The present disclosure has the effect of providing the position and number of inflators that do not restrict the movement of a user wearing a body protection device during work or daily life.

[0031] The human body protection device of the present disclosure is described below with reference to the attached drawings.

[0032] Figure 1 illustrates the expansion process of an industrial body protection device. Figure 2 illustrates the expansion process of a household body protection device. Figure 3 illustrates a schematic diagram of a body protection device.

[0033] The human body protection device (100) may include an industrial human body protection device or a daily life human body protection device, depending on the usage environment or user. The industrial human body protection device can protect the user's head, neck, front upper body, back upper body, and hips. The daily life human body protection device can protect the user's hips and legs.

[0034] A human body protection device (100) may include an outer shell (200), an airbag (300), an inflator (400), a battery (500), an output unit (600), a sensor module (SM), and a control module (CM). Not all of these components are essential components of the human body protection device, and the device may be implemented with fewer or more components.

[0035] Referring to FIGS. 1 and 2, a user can perform work or daily life while wearing or hanging a body protection device (100) on his or her body, and the body protection device (100) can inflate when it detects a danger such as a fall / fall / collision to protect the user's body from danger.

[0036] The human body protection device (100) of FIG. 1 can protect the user's body, such as the head, neck, and spine, by inflating before colliding with the ground due to a fall or drop of a user working at a height. Alternatively, the human body protection device (100) of FIG. 2 can protect the user's body, such as the hips or pelvis, by inflating before colliding with the ground due to a fall during daily life. In addition, the human body protection device (100) can detect the possibility of a collision with an external object and inflate before colliding to protect the user's body.

[0037] The outer shell (200) forms the exterior of the human body protection device (100) before expansion, and may have various exterior shapes such as clothing that can be worn on the user's body, upper garments, lower garments, harnesses, belts, and clothing that can be attached to a harness.

[0038] The outer shell (200) may be made of a material that is harder than the airbag (300) and stronger than the airbag (300) due to external friction or impact. The outer shell (200) may be made of a fabric material that does not stretch due to external force. The airbag (300) may be made of a material that is softer than the outer shell (200), may be made of a material that stretches due to external force, and may be made of a resin material or a fabric material.

[0039] The outer shell (200) may include an inner shell space (210) capable of storing an airbag (300) before inflation. The inner shell space (210) may be provided with an outer shell fixing member (not shown) capable of fixing the airbag (300) before inflation on the inner surface of the inner shell space (210).

[0040] The battery (500) can supply power to the inflator (400), the output unit (600), the sensor module (SM), and the control module (CM). The battery (500) can be detachably installed in the human body protection device (100).

[0041] The output unit (600) may provide a voice signal or a visual signal to the user or a person nearby according to the airbag inflation signal generated from the processor (110). Alternatively, the output unit (600) may provide a notification to replace the battery (500) as a voice signal or a visual signal when the battery (500) is in a low battery state.

[0042] The sensor module (SM) and the control module (CM) are configured separately and connected by wire or wirelessly, and the sensor module (SM) can transmit sensed data to the control module (CM). In this case, the control module (CM) can be installed inside the control box (CB).

[0043] Alternatively, the sensor module (SM) and the control module (CM) are configured to be integrally coupled with each other, and the sensor module (SM) can transmit sensed data to the control module (CM). The combined sensor module (SM) and control module (CM) can both be provided inside a control box (CB).

[0044] The control module (CM) may include a processor (110), a memory (140), and a communication unit (150). The control module (CM) may be composed of a processor (110), a memory (140), and a communication unit (150) integrally combined on a circuit board (not shown).

[0045] The processor (110) is electrically connected to the inflator (400), output unit (600), sensor module (SM), memory (140), and communication unit (150), and can transmit and receive data signals with each component, calculate data, and control each component.

[0046] The processor (110) can receive data sensed by the sensor module (SM), process the sensed data using the airbag inflation determination program stored in the memory (140), or determine whether airbag inflation is necessary based on the sensed data, and transmit an airbag inflation signal to the inflator (400).

[0047] The processor (110) can transmit an airbag inflation signal or a user danger signal to an external device (not shown) via the communication unit (150). The communication unit (150) can transmit an airbag inflation signal or a signal regarding a user's fall / collision / dropping, etc. to the outside when the airbag (300) is inflated.

[0048] The sensor module (SM) can sense the acceleration and / or angular velocity of a user wearing a human body protection device (100). The sensor module (SM) can include one sensor unit (SP) or multiple sensor units (SM).

[0049] Each sensor unit (SP) may include at least one of an acceleration sensor (120) and an angular velocity sensor (130). In other words, the sensor unit (SP) may include only an acceleration sensor (120), only an angular velocity sensor (130), or both an acceleration sensor (120) and an angular velocity sensor (130).

[0050] Furthermore, the sensor unit (SP) may include a sensor communication unit (SPC) for transmitting sensing data. The sensor communication unit (SPC) may wirelessly transmit sensing data to the processor (110) when the sensor unit (SP) is not connected to the processor (110) by wire.

[0051] When a sensor module (SM) is composed of multiple sensor units (SP), the configurations of some sensor units (SP) and other sensor units (SP) may be different from each other, such as some sensor units (SP) including only an acceleration sensor (120) and other sensor units (SP) including only an angular velocity sensor (130).

[0052] The acceleration sensor (120) can be obtained by measuring the acceleration of the human body. Specifically, the acceleration sensor (120) can be obtained by measuring the acceleration of the human body along the longitudinal axis, y-axis, and z-axis.

[0053] The angular velocity sensor (130) can be obtained by measuring the angular velocity of the human body. Specifically, the angular velocity sensor (130) can be obtained by measuring the pitch, roll, and yaw angular velocities of the human body.

[0054] The sensor unit (SP) described below can be applied to both cases where it is configured separately from the control module (CM) and cases where it is integrated with the control module (CM).

[0055] Figure 4 illustrates the location of sensor modules according to various embodiments.

[0056] Referring to Fig. 4, the sensor module (SM) may be composed of one or more sensor units (SP). In order for the human body protection device (100) to determine whether the user has fallen or fallen, it must accurately sense the user's movements and accurately analyze the sensed data to determine whether or not a fall or fall has occurred.

[0057] To do this, the sensor unit (SP) must be positioned in a location where it can accurately measure the user's movements, and the number of sensor units (SP) also acts as an important variable.

[0058] Figure 4(a) illustrates various embodiments in which one or more sensor units (SP) may be positioned on the front of the user. Figure 4(b) illustrates various embodiments in which one or more sensor units (SP) may be positioned on the back of the user. Figure 4(c) illustrates various embodiments in which one or more sensor units (SP) may be positioned on the side of the user.

[0059] The user's center line (CL) is an imaginary line formed at the center of the left and right sides of the user's front or back, and can be the spine line viewed from the user's front or back.

[0060] When the sensor module (SM) is composed of a single first sensor unit (SP1), the first sensor unit (SP1) may be positioned on the user's center line (CL). In other words, the first sensor unit (SP1) may be positioned on the front or back of the user on the user's spine line.

[0061] When the user's posture and movement are sensed only with one first sensor unit (SP1) located on a part other than the user's center line (CL), the first sensor unit (SP1) may falsely sense that the user has fallen or fallen when the user turns left or right with respect to the normal direction of the ground. Therefore, when configuring a human body protection device (100) with only one first sensor unit (SP1), it is preferable to place the first sensor unit (SP1) on the user's center line (CL).

[0062] In various embodiments, the first sensor unit (SP1) may be located at any one of the forehead area (m), the back of the head area (b1), and the crown area (C1) of the user's head. In this case, the first sensor unit (SP1) may be installed in a hat, helmet, headband, etc. worn by the user. Specifically, the first sensor unit (SP1) may be installed on the inner side of a safety helmet used at a work site or a helmet used in daily life. In this case, the first sensor unit (SP1) may wirelessly transmit and receive sensing data to and from the control module (CM).

[0063] In various embodiments, the first sensor unit (SP1) may be positioned on the front (a2) or back (b2) of the user on a first virtual line (SL1) connecting the upper and lower portions of the user's shoulders. Alternatively, the first sensor unit (SP1) may be positioned within a first predetermined distance from the first virtual line (SL1). The first sensor unit (SP1) may be positioned between a second virtual line (SL2) positioned at a first predetermined distance downward from the first virtual line (SL1) and a third virtual line (SL3) positioned at a first predetermined distance upward from the first virtual line (SL1). In this case, the first sensor unit (SP1) may be positioned on the outer shell (200) worn by the user.

[0064] When a user falls or falls, the user's torso moves around the pelvis, and the part of the user's torso where the greatest torque is applied is near the first virtual line (SL1) connecting the tops of both of the user's shoulders. Therefore, the first sensor unit (SP1) should be located near this area to most accurately sense the user's posture or movement.

[0065] In various embodiments, the first sensor unit (SP1) may be positioned either on the user's forehead area (a3) ​​or on the rear portion (b3) corresponding to the user's forehead area. In this case, the first sensor unit (SP1) may be positioned on the outer shell (200) worn by the user.

[0066] In various embodiments, the first sensor unit (SP1) may be positioned either at the user's navel area (a4) or at the rear portion (b4) corresponding to the user's navel. In this case, the first sensor unit (SP1) may be positioned on the outer shell (200) worn by the user.

[0067] In various embodiments, the first sensor unit (SP1) may be positioned at either the front central portion (a5) of the belt worn by the user or the rear central portion (b5) of the belt.

[0068] When the sensor module (SM) is composed of only two second sensor units (SP2), the second sensor unit (SP2) may be composed of a second-first sensor unit (SP2-1) and a second-second sensor unit (SP2-2). The second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be arranged symmetrically with respect to the user's spine line.

[0069] By using two second sensor units (SP2) positioned at the same height and horizontally spaced from each other, the processor (110) can accurately analyze the height difference between the left / right sides of the user, the rotation direction difference, the angle difference, etc. based on the data sensed by the two second sensor units (SP2), and can accurately analyze the user's posture or movement.

[0070] In various embodiments, the second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be positioned on either side of the front (all, a12) or rear (bll, bl2) portion of the user's torso, adjacent to the boundary between the torso and the arms. In this case, the first sensor unit (SP1) may be positioned on the outer shell (200) worn by the user.

[0071] Here, the reason why the 2-1 sensor unit (SP2-1) and the 2-2 sensor unit (SP2-2) are not placed on the front or back of the user's arm is because the arm is the body part that moves most frequently during work or daily life, and thus has a high probability of malfunction. Therefore, the 2-1 sensor unit (SP2-1) and the 2-2 sensor unit (SP2-2) can be placed on the torso part that moves relatively less compared to the arm.

[0072] In addition, the farther apart the distance between the 2-1 sensor unit (SP2-1) and the 2-2 sensor unit (SP2-2) is, the more accurately the user's posture or movement can be analyzed using the data sensed by each sensor unit. Therefore, the 2-1 sensor unit (SP2-1) and the 2-2 sensor unit (SP2-2) are placed at both ends of the torso adjacent to the arms.

[0073] In various embodiments, the second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be positioned on one of the user's upper shoulders (cll, c12) and one of the two sides (c21, c22) of the user's torso. In this case, the second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be positioned on the outer shell (200) worn by the user.

[0074] In various embodiments, the second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be respectively positioned on both sides (c31, c32) of the belt worn by the user. In this case, the second-first sensor unit (SP2-1) and the second-second sensor unit (SP2-2) may be positioned on the belt-shaped outer shell (200) worn by the user.

[0075] The sensor module (SM) may be composed of a plurality of third sensor units (SP3). The third sensor unit (SP3) may be composed of a third-first sensor unit (SP3-1), a third-second sensor unit (SP3-2), a third-third sensor unit (SP3-3), etc.

[0076] The 3-1 sensor unit (SP3-1), the 3-2 sensor unit (SP3-2), the 3-3 sensor unit (SP3-3), etc. may be placed in different locations among the locations where the above-described 1st sensor unit (SP1) or 2nd sensor unit (SP2) may be placed.

[0077] For example, if the sensor module (SM) is composed of two third sensor units (SP3), two of them may be placed at different locations in the part where the first sensor unit (SP1) can be positioned. Alternatively, if the sensor module (SM) is composed of three third sensor units (SP3), one may be placed in the part where the first sensor unit (SP1) can be positioned, and two may be placed in the part where the second sensor unit (SP2) can be positioned. Alternatively, if the sensor module (SM) is composed of two third sensor units (SP3), one may be placed in the part where the first sensor unit (SP1) can be positioned, and one may be placed in the part where the second sensor unit (SP2) can be positioned.

[0078] In this way, two or more sensing data can be acquired from two or more body parts of a user wearing a human body protection device (100). The processor (110) can acquire the user's posture or movement information by using the respective position information of the plurality of third sensor units (SP3), relative position information, detailed sensor information constituting the third sensor unit (SP3), and the plurality of sensing data sensed by the plurality of third sensor units (SP3).

[0079] Referring again to FIG. 1, the outer shell (200) may include a front outer shell (200a) covering the user's neck and front of the body, and a rear outer shell (200b) covering the back of the user's body.

[0080] The outer shell (200) may have various structures depending on the inflation state of the airbag (300).

[0081] In various embodiments, when the inflated airbag (300) has a larger volume than the inner space of the outer shell (210), the inflated airbag (300) may not be exposed to the outside of the outer shell (200). In this case, the outer shell (200) may include an outer shell expansion portion (220a, 220b) that expands the volume of the inner space of the outer shell (210) corresponding to the volume of the inflated airbag (300). The outer shell expansion portion (220a, 220b) is located on the inside of the outer shell (200) before the airbag (300) is inflated, but is exposed to the outside of the outer shell (200) after the airbag (300) is inflated, thereby expanding the volume of the inner space of the outer shell (210).

[0082] In various embodiments, when the inflated airbag (300) has a volume smaller than or equal to the volume of the inner space of the outer shell (210), the inflated airbag (300) is not exposed to the outside of the outer shell, and the outer shell (200) may be double-sewn at the seams between the outer shells (200) to prevent them from bursting due to the instantaneous expansion of the airbag (300).

[0083] In various embodiments, if the inflated airbag (300) has a larger volume than the inner space of the outer shell (210), the inflated airbag (300) may be exposed to the outside of the outer shell (200). In this case, the outer shell (200) may have a quick-burst zipper or Velcro fastening portion to adjust the position at which the inflated airbag (300) is exposed to the outside.

[0084] The airbag (300) is provided in a fixed state by being accommodated in the inner space (210) of the outer shell before inflation.

[0085] The airbag (300) can be inflated by the inflator (400). Specifically, the airbag (300) can be inflated by receiving compressed gas stored in the gas cartridge (410) through the operation of the inflator (400). The inflated airbag (300) can be inflated only within the inner space (210) of the outer shell expanded by the outer shell expansion portions (220a, 220b), or can be inflated only within the inner space (210) of the outer shell without the outer shell expansion portions (220a, 220b), or can be inflated by protruding so as to be exposed to the outside of the outer shell (200).

[0086] The airbag (300) may include a front airbag (300a) that protects the user's head, neck, shoulders, and front part of the body (chest, stomach), and a rear airbag (300b) that protects the back part of the user's body (back, hips).

[0087] The front airbag (300a) is provided in the internal space of the front shell (200a) before inflation. The front airbag (300a) may be inflated from the inside to the outside of the front shell (200a) or may be inflated only from the inside.

[0088] The rear airbag (300b) is provided in the internal space of the rear shell (200b) before inflation. The front airbag (300a) may be inflated from the inside to the outside of the front shell (200a) or may be inflated only from the inside.

[0089] Referring to FIG. 2, the outer shell (200) may include a belt-type outer shell (200c). The belt-type outer shell (200c) may be worn on the user's pelvis. In this case, the airbag (300) may include a buttocks airbag (300c) that protects the user's buttocks and pelvis. The buttocks airbag (300c) is provided in the inner space of the belt-type outer shell (200c), and when inflated, it may inflate from the inside to the outside of the belt-type outer shell (200c) or inflate only from the inside.

[0090] Airbags (300) may be provided in one or more configurations to protect various parts of the body. The airbags (300) can be directly inflated by compressed gas injection. Since the airbags (300) are spaces into which gas is injected, they can be filled with compressed gas released from a gas cartridge (410).

[0091] Figure 5 is a drawing showing the location of the sensor part in a vest or harness type body protection device.

[0092] The front outer shell (200a) of a vest or harness type body protection device may include a left front body plate (200aa) and a right front body plate (200ab). The rear outer shell (200b) may include a rear body plate (200ba). The left front body plate (200aa) and the right front body plate (200ab) are connected to the upper portion of the rear body plate (200ba).

[0093] The back body plate (200ba) can cover the back of a user wearing a body protection device (100). The back body plate (200ba) can have a circulation opening (200b-l) in the center, and the back of a user wearing a harness can be exposed.

[0094] The upper side of the left front body (200aa) can be connected to the upper side of the rear body (200ba), and the side of the left front body (200aa) can be connected to the side of the rear body (200ba) with a buckle. The upper side of the right front body (200ab) can be connected to the upper side of the rear body (200ba), and the side of the right front body (200ab) can be connected to the side of the rear body (200ba) with a buckle.

[0095] The user's left arm may be exposed between the side of the left front body (200aa) and the side of the rear body (200ba), and the user's right arm may be exposed between the side of the right front body (200ab) and the side of the rear body (200ba).

[0096] The left front body (200aa) and the right front body (200ab) can be connected to each other with a fastening member (200a-l) such as a buckle to prevent them from being detached from the user's body.

[0097] The left front body panel (200aa) and the right front body panel (200ab) may be separated from each other even when fastened together with buckles. Separating the left front body panel (200aa) and the right front body panel (200ab) increases the user's mobility and allows body heat to be efficiently discharged to the outside.

[0098] The left front body plate (200aa) and the right front body plate (200ab) may have a vertically elongated shape and may be shaped to be positioned on the user's torso. This may prevent the user's arm movements from being impeded.

[0099] Referring to Fig. 5(a), the sensor module (SM) may be provided on the user's left front body (200aa) and / or the user's right front body (200ab). The sensor module (SM) may be provided with two second sensor parts (SP2), and the two second sensor parts (SP2) may be arranged symmetrically with respect to the user's center line (CL) at the same height on the left front body (200aa) and the right front body (200ab). The two second sensor parts (SP2) may be arranged between the user's shoulder and chest, or may be arranged on the user's stomach.

[0100] Referring to Fig. 5(b), a sensor module (SM) may be installed on the user's back body (200ba).

[0108] Referring to Fig. 7(a), if the sensor module (SM) is configured with one first sensor unit (SP1), the first sensor unit (SP1) may be provided on the back panel (200ac). The back panel (200ac) may be positioned beyond the point where the user's neck and back meet and up to the virtual shoulder line connecting both shoulders. In this case, the first sensor unit (SP1) may be positioned on the user's virtual shoulder line.

[0109] Referring to FIG. 7(b) and FIG. 8, the rear outer shell (200b) can be attached and detached to the rear of the harness (10) from the rear of the user wearing the harness (10). The rear outer shell (200b) can include a rear airbag (300b) therein. The rear airbag (300b) can inflate within the rear outer shell (200b) when inflated.

[0110] The rear outer shell (200b) may include an upper rear body plate (200ba-1) that horizontally covers the user's upper back, a left rear body plate (200ba-2) that extends downward from the left side of the upper rear body plate (200ba-l), a right rear body plate (200ba-3) that extends downward from the right side, and a lower rear body plate (200ba-4) that horizontally connects the lower sides of the left rear body plate (200ba-2) and the right rear body plate (200ba-3).

[0117] Figure 9 is an exploded view of a belt-type human body protection device. Figure 10 illustrates a configuration diagram of a belt-type human body protection device.

[0118] Referring to FIGS. 9 and 10, a belt-type human body protection device may include a belt-type outer shell (200c) that can be worn around the user's waist line.

[0119] The belt-type outer shell (200c) may include a buttocks airbag (300c) inside. The buttocks airbag (300c) may be expanded by protruding outward through a quick burst portion (240) formed in the lower portion of the belt-type outer shell (200c) when inflated.

[0120] The belt-type outer shell (200c) has a long shape in the longitudinal direction so that it can be wrapped around the user's waist, and has male and female buckles (250) at both ends so that the user can fasten the male and female buckles (250) to secure the belt-type outer shell (200c) to the user's waist.

[0121] Referring to Fig. 10, when the sensor module (SM) is configured with one first sensor unit (SP1), the first sensor unit (SP1) may be placed on a belt-shaped outer shell (200c) corresponding to the rear center portion of the user. Alternatively, the first sensor unit (SP1) may be placed on a buckle (250) corresponding to the front center portion of the user.

[0122] When the sensor module (SM) is composed of two second sensor units (SP2), the two second sensor units (SP2) may be respectively positioned on the belt-shaped outer shell (200c) corresponding to the front and rear central portions of the user. Alternatively, the two second sensor units (SP2) may respectively be positioned on the belt-shaped outer shell (200c) corresponding to both sides of the user.

[0123] Hereinafter, the inflator will be described with reference to FIGS. 3, 5, 6, 8 to 10.

[0124] An inflator (400) is a device that inflates an airbag (300). The inflator (400) operates to open a gas cartridge (410) by receiving an airbag inflation signal, and supplies compressed gas inside the opened gas cartridge (410) to the airbag (300) to inflate the airbag (300). Specifically, the inflator (400) can open an opening / closing portion (420) by the received airbag inflation signal to supply compressed gas stored in the gas cartridge (410) to the airbag (300).

[0125] The inflator (400) is installed on the outer surface of the outer shell (200) and can supply compressed gas to the airbag (300) located inside the outer shell (200). Alternatively, the inflator (400) can be installed on the outer surface of the airbag (300) and can supply compressed gas to the airbag (300).

[0126] The inflator (400) can supply compressed gas to the airbag (300) through a hose (not shown), or can be directly connected to the airbag (300) to supply compressed gas.

[0127] The inflator (400) may include a gas cartridge (410) and an opening / closing part (420) for opening / closing the gas cartridge (410).

[0128] The inflator (400) may include a gas cartridge (410) and an opening / closing part (420) connected to the gas cartridge (410) to open / close the gas cartridge (410).

[0129] The gas cartridge (410) is composed of one or a combination of two or more of carbon dioxide, nitrogen, oxygen, etc., and can store compressed gas compressed at high pressure in the internal space of the cartridge (not shown).

[0130] The gas cartridge (410) may be formed of a metal material such as iron, aluminum, magnesium, etc. The gas cartridge (410) has a cylindrical shape and may include an opening (not shown) on one or both sides of the cylindrical shape.

[0131] The opening / closing part (420) is coupled to the opening (not shown) to open / close the gas cartridge (410) in response to the airbag inflation signal of the processor (110), and can supply compressed gas to the airbag (300) through the opening / closing body discharge hole (not shown) described later to inflate the airbag (300).

[0132] The opening / closing portion (420) can be directly connected to the outer surface of the airbag (300), or can be connected to the outer surface of the outer shell (200) so as to penetrate the directly overlapping outer shell (200) and the airbag (300) to supply compressed gas into the interior of the airbag (300). In this case, the discharge hole of the opening / closing portion (420) can be connected to the airbag hole (301) and the outer shell hole (201).

[0133] The inflator (400) must have a predetermined length because the opening / closing portion (420) is connected to one end of the gas cartridge (410) in the longitudinal direction. Therefore, the inflator (400) may restrict the user's movements. For example, if the inflator is positioned perpendicular to the folded portion of the user's upper and lower body, the inflator may impede the user's movements when bending the upper body.

[0134] Additionally, when a fallen user collides with the ground, if the inflator (400) is positioned between the ground and the user's body, the impact of the ground may be directly transmitted to the user's body through the inflator (400). This may cause irreparable damage to the user's body.

[0135] It is preferable that the inflator (400) not be positioned high above the user's spine line. In other words, it is preferable that the inflator (400) not be positioned within a predetermined distance to the left or right of the user's spine line.

[0136] The inflator (400) can be installed on the front outer shell (200a), the rear outer shell (200b), and the belt outer shell (200c) of the human body protection device (100) worn by the user.

[0137] Figure 11 illustrates various examples of where the inflator can be positioned.

[0138] Referring to FIG. 11(a), the inflator (400) may include a front inflator (400a-l, 400a-2) positioned on the front of the user's upper body.

[0139] In various embodiments, the front inflator may be positioned on the front of the upper body a predetermined distance (S) from the user's spine line (CL). The reason for positioning the front inflator a predetermined distance from the spine line (CL) is to prevent damage to the spine by the inflator when impacting the ground.

[0140] The longitudinal direction of the front inflator is aligned with the spine line (CL), ensuring that the inflator does not intersect the spine line (CL). This avoidance of the inflator intersecting the spine line (CL) is intended to prevent damage to the spine by positioning the inflator between the ground and the spine during impact.

[0141] Referring to FIGS. 5 and 6, a front inflator may be provided on at least one of the left front body plate (200aa) and the right front body plate (200ab) of the front shell (200a). The front inflator may include one or more front inflators (400a-l, 400a-2) for supplying compressed gas to the front airbag (300a). The front inflator may be configured as one or two depending on the capacity of the front airbag (300a). The two front inflators may be located at the center portion of the left front body plate (200aa) and the center portion of the right front body plate (200ab). However, the present invention is not limited thereto, and the two front inflators may be located at the upper or lower portions of the left front body plate (200aa) and the right front body plate (200ab).

[0142] If the inflator is positioned at the lower portion of the left front body (200aa) and the right front body (200ab), the weight of the inflator may cause the left front body (200aa) and the right front body (200ab) to shake during the user's activities. In addition, if the inflator is positioned at the upper portion of the left front body (200aa) and the right front body (200ab), the volume of the inflator may cause the user to have difficulty moving their arms.

[0143] Since the central portions of the left front body (200aa) and the right front body (200ab) are fastened to each other through buckles, the front inflator is positioned in the central portions of the left front body (200aa) and the right front body (200ab), which distributes the weight of the inflator to the entire body protection device (100), and can have the effect of preventing the left front body (200aa) and the right front body (200ab) from shaking due to the weight of the inflator.

[0144] Referring to FIG. 11(b), the inflator (400) may include a rear inflator (400b-l, 400b-2) positioned on the rear of the user's upper body.

[0145] In various embodiments, the rear inflator may be positioned on the rear of the upper body a predetermined distance (S) from the user's spine line (CL). The longitudinal direction of the inflator is arranged parallel to the spine line (CL), so that the inflator is positioned so as not to intersect the spine line (CL).

[0146] Referring to FIGS. 5 and 8, the rear inflator may be provided on at least one of the left rear body plate (200ba-2) and the right rear body plate (200ba-3) of the rear outer shell (200b). The rear inflator may include one or more rear inflators (400b-l, 400b-2) for supplying compressed gas to the rear airbag (300b). The rear inflator may be configured as one or two depending on the capacity of the rear airbag (300b). The two rear inflators may be located at the center portion of the left rear body plate (200ba-2) and the center portion of the right rear body plate (200ba-3). However, the present invention is not limited thereto, and the two rear inflators may be located at the upper or lower portions of the left rear body plate (200ba-2) and the right rear body plate (200ba-3).

[0147] Considering the center of gravity of the rear body (200ba), it is preferable that the rear inflator be located in the center of the left rear body (200ba-2) and the right rear body (200ba-3), but be located so as to overlap the area where the intersection of the harness (10) is located.

[0148] Alternatively, the rear inflator may be located on the left rear body plate (200ba-2) and the right rear body plate (200ba-3) corresponding to the left and right sides of the circulation opening (200b-l).

[0149] Referring to FIGS. 11(a) to 11(c), in various embodiments, the inflator (400) may include a lower body inflator (400d-l 400d-6) positioned on the user's lower body. Positioning the inflator on the lower body rather than the upper body can prevent the inflator from damaging the user's spine due to impact with the ground.

[0150] The lower body inflator can be positioned on the user's thigh. At least one lower body inflator can be positioned on at least one of the front (400d-l, 400d-2), back (400d-3, 400d-4), and side (400d-5, 400d-6) of the user's thigh. The lower body inflator can be arranged parallel to the length of the user's leg. Although not shown, the lower body inflator can be fastened to one of the extended outer shell extending downward from the outer shell of the human body protection device (100), the leg fastening portion of a harness worn by the user, and the belt-type extended outer shell extending from the belt-type outer shell (200c).

[0151] Referring to FIG. 11(c), the inflator (400) may include arm inflators (400e-l, 400e-2) positioned on the user's arm. Positioning the inflator on the arm rather than the torso may prevent the inflator from damaging the user's spine due to a collision with the ground. Referring to FIG. 13(c), the arm inflator may be positioned on the outer side (400e-l, 400e-2) of the upper arm of the user's arm.

[0152] Referring to FIGS. 11(a) to 11(c), the inflator (400) may include a belt-type inflator (400c) installed on a belt-type outer shell (200c) worn by a user.

[0153] The gas cartridge (420) of the inflator (400a, 400b) used in the vest-type, harness-type, and harness-combined body protection device (100) has a relatively larger capacity than the gas cartridge (420) of the inflator (400c) used in the belt-type body protection device (100). Therefore, the inflator (400c) of the belt-type body protection device (100) also has a relatively short length and small volume.

[0154] Referring to FIG. 11(a), the inflator (400) may include a belt-type inflator (400c-l, 400c-2) that is arranged parallel to the horizontal direction (i.e., the longitudinal direction of the belt-type outer shell) rather than the vertical direction in the longitudinal direction at the front part of the user in the belt-type outer shell (200c). This is because, since the part where the belt-type human body protection device is worn is the part where the upper and lower bodies fold, it is difficult to bend the upper body if the belt-type inflator (400c-l, 400c-2) is arranged in the vertical direction.

[0155] Referring to FIG. 10, the belt-type inflator (400c-l, 400c-2) may be configured as one or more for supplying compressed gas to the buttock air bag (300c). In particular, the belt-type inflator (400c-l, 400c-2) may be arranged to be placed on the user's stomach. The opening (not shown) of the gas cartridge (420) of the belt-type inflator (400c-l, 400c-2) may be arranged to face outward from the user's center line.

[0156] Referring to Fig. 11(b), it is preferable not to place the belt-type inflator (400c) on the rear part of the user. This is because the pelvic bone is located on the rear part of the user wearing the belt-type outer shell (200c), so the inflator may break the pelvic bone when colliding with the ground.

[0157] Referring to FIG. 11(c), the inflator (400) may include a belt-type inflator (400c-3, 400c-4) installed on a belt-type outer shell (200c) corresponding to the user's side. This is because when the user falls or falls, the user collides with the ground in the direction of the hip or forward, so the belt-type inflator (400c-3, 400c-4) located on the user's side is less likely to collide with the ground.

[0158] Referring to FIG. 10, the belt-type inflator (400c-3, 400c-4) may be configured as one or more for supplying compressed gas to the buttock air bag (300c). In particular, the belt-type inflator (400c-3, 400c-4) may be arranged to be placed on the user's side. The opening (not shown) of the gas cartridge (420) of the belt-type inflator (400c-3, 400c-4) may be arranged to face downward.
