Description

Airbag structure {Airbag Structure}

The present invention relates to an airbag structure.

In modern society, the elderly population is rapidly increasing due to aging, and as a result, safety accidents among the elderly are being raised as an important social problem. Among these safety accidents, falling accidents occur frequently in the elderly, and surgery is difficult for the elderly due to their weakened physical abilities, and even if the surgery is performed successfully, they have difficulty recovering. Additionally, in the event of a fall accident, the physical impact can cause serious injuries to the head, neck, and spine. Therefore, there is a need for a protection system that can absorb impact energy to prevent injuries due to falls.

To protect the body from falling accidents, various technologies such as hip protectors and wearable airbags are being developed. However, hip protectors cause discomfort when worn, so users tend not to want to wear them. Meanwhile, wearable airbags can be expected to have the ability to prevent injuries to the human body caused by falls. However, the wearable airbag according to the prior art has a disadvantage in that it is difficult to manufacture the airbag structure. As shown in FIG. 10, the conventional airbag structure must be manufactured in a flat shape, and then sewing work must be performed on adjacent edges to implement a three-dimensional shape. Since this sewing work is manual, not only does manufacturing time and manufacturing cost increase, but there is also the problem that quality varies depending on the operator.

furthermore. Since the conventional airbag structure has a three-dimensional shape even before fluid injection, folding is difficult. Additionally, design is difficult because a planar development (2D) must be constructed from a three-dimensional shape (3D).

1 to 3, in the airbag structure according to the first embodiment, the first member 110 and the second member 120 are combined so that a space is formed inside, and the first member 110 and Fluid is injected between the second members 120, the main body 100 having a plurality of predetermined points A spaced apart from each other on the side, and a predetermined length from the plurality of predetermined points A to the inside of the main body 100. It includes a plurality of coupling portions 200 that couple the first member 110 and the second member 120 to extend.

The main body 100 is expanded by injecting fluid from a fluid supply means. Here, the main body 100 may be used as the wearable airbag itself or as a part of the wearable airbag. As shown in FIG. 3, a space may be formed inside the main body 100 by combining the first member 110 and the second member 120. That is, the first member 110 can be the lower surface of the main body 100, and the second member 120 can be the upper surface of the main body 100, and the first member 110 and the second member 120 When fluid is injected into the space between the main body 100, the main body 100 may expand. For example, the main body 100 may be formed by combining the edge of the first member 110 and the edge of the second member 120.

As shown in FIG. 1, the main body 100 may extend long in one direction. At this time, a plurality of predetermined points A spaced apart from each other along the longitudinal direction may be disposed on the side of the main body 100. At this time, a plurality of predetermined points A may be formed on both end sides of the main body 100. For example, a plurality of predetermined points A may be disposed on the side of the main body 100 at regular intervals along the longitudinal direction. However, the plurality of predetermined points (A) do not necessarily have to be spaced apart at regular intervals, and the intervals between the plurality of predetermined points (A) may change according to certain rules or change randomly. Here, the plurality of predetermined points A are the starting points of the coupling portion 200, and specific details regarding this will be described later.

The coupling portion 200 serves to couple the first member 110 and the second member 120. Here, the coupling portion 200 is formed to extend a predetermined length from a predetermined point A of the main body 100 into the interior of the main body 100, and couples the first member 110 and the second member 120. At this time, since the coupling portion 200 extends from a plurality of predetermined points A, a plurality of coupling portions 200 may be formed. In addition, since a plurality of predetermined points A are formed on the side surfaces of both ends of the main body 100, coupling portions 200 are formed on both end edges of the coupled first member 110 and second member 120. It can be. Here, the space between two adjacent coupling parts 200 among the plurality of coupling parts 200 can be defined as a predetermined space 300. When fluid is injected into the main body 100, fluid is also injected into the predetermined space 300. It can be. When fluid is injected into the predetermined space 300, the predetermined space 300 excluding the coupling portion 200 expands to form a three-dimensional shape, and when viewed based on the cross section (see FIG. 4), the predetermined space 300 The main body 100 and the first and second members 110 and 120 change from a straight line to a curved line. Accordingly, the overall length of the side of the main body 100 on which the coupling portion 200 is formed may be reduced. As shown in FIG. 3, the side of the main body 100 on which the coupling portion 200 is formed is defined as one side 100a of the main body 100, and the main body opposite to one side 100a of the main body 100 When defining the side of 100 as the other side 100b of the main body 100, the length of one side 100a of the main body 100 on which the coupling portion 200 is formed is the other side 100b of the main body 100. ), the main body 100 can be bent in the direction in which the coupling portion 200 is formed. That is, the main body 100 can be bent so that one side 100a of the main body 100 on which the coupling portion 200 is formed is curved inward. In this way, the main body 100 is bent when fluid is injected, thereby realizing a three-dimensional shape.

Meanwhile, the coupling portion 200 may couple the first member 110 and the second member 120 using, for example, adhesive or stitching, but is not necessarily limited thereto.

Figure 5 is a plan view of an airbag structure according to a second embodiment of the present invention, and Figure 6 is a perspective view of an airbag structure according to a second embodiment of the present invention.

As shown in Figures 5 and 6, the airbag structure according to the second embodiment has a first member 110 and a second member 120 combined so that a space is formed inside, and the first member 110 and Fluid is injected between the second members 120, and a plurality of first predetermined points A1 spaced apart from each other are disposed on one side 100a, and a plurality of second predetermined points spaced apart from each other are disposed on the other side 100b ( A main body 100 on which A2) is disposed, a plurality of first members 110 and second members 120 connected to each other so that a predetermined length extends from a plurality of first predetermined points A1 into the interior of the main body 100. The first coupling portion 210, and a plurality of second coupling portions that couple the first member 110 and the second member 120 to extend a predetermined length from the plurality of second predetermined points A2 into the interior of the main body 100. Includes 2 coupling portions 220.

While the airbag structure according to the first embodiment has a plurality of coupling portions 200 formed on one side 100a of the main body 100 (see FIG. 3), the airbag structure according to the second embodiment has the main body 100 ) There is a difference in that a plurality of first coupling parts 210 are formed on one side (100a) of the main body 100, and a plurality of second coupling parts 220 are formed on the other side (100b) of the main body 100 (Figure 6 reference). Therefore, the airbag structure according to the second embodiment will be described focusing on the differences, omitting overlapping content from the airbag structure according to the first embodiment.

The airbag structure according to the second embodiment includes a first member 110 and a second member 120 such that a predetermined length extends inward from a plurality of first predetermined points A1 on one side 100a of the main body 100. A plurality of first coupling portions 210 are formed to couple the first member 110 and the first member 110 so that a predetermined length extends inward from the second predetermined point A2 on the other side 100b of the main body 100. A plurality of second coupling portions 220 that couple the two members 120 may be formed. At this time, the first coupling portion 210 formed on one side 100a of the main body 100 and the second coupling portion 220 formed on the other side 100b of the main body 100 may be formed at positions corresponding to each other. there is. Here, the space between two adjacent first coupling parts 210 among the plurality of first coupling parts 210 may be defined as the first predetermined space 310, and the space between two adjacent first coupling parts 210 among the plurality of second coupling parts 220 may be defined as the first predetermined space 310. The space between the second coupling portions 220 may be defined as a second predetermined space 320 . At this time, when fluid is injected into the main body 100, the fluid may be injected into the first predetermined space 310 and the second predetermined space 320. When fluid is injected into the first and second predetermined spaces (310, 320), the first and second predetermined spaces (310, 320) excluding the first and second coupling portions (210, 220) expand and form a three-dimensional shape, When viewed in cross section (see FIG. 7), the main body 100 and the first and second members 110 and 120 change from straight lines to curves in the first and second predetermined spaces 310 and 320. Accordingly, as shown in FIG. 6, the length of one side 100a and the other side 100b of the main body 100 on which the first and second coupling portions 210 and 220 are formed may be reduced. In this way, since the length of one side (100a) and the other side (100b) of the main body 100 is reduced, the main body 100 is perpendicular to the virtual line (V) connecting one side (100a) and the other side (100b). It can bend in any direction. That is, since the first and second coupling parts 210 and 220 are formed on both sides 100a and 100b of the main body 100, respectively, the first coupling part 210 formed on one side 100a of the first main body 100 ) direction, or not bent in the direction of the second coupling portion 220 formed on the other side 100b of the main body 100, but in the third direction (for example, perpendicular to one side of the main body 100). It can be bent in any direction (see arrow in FIG. 6). In this way, the main body 100 is bent when fluid is injected, thereby realizing a three-dimensional shape.

Meanwhile, between one side 100a and the other side 100b of the main body 100 (the center of the main body 100), a first member 110 and a second member 120 are formed along the longitudinal direction of the main body 100. ) may be formed. Therefore, when fluid is injected into the main body 100, the third coupling portion 230 does not decrease in length, and is connected to one side 100a of the main body 100 where the first and second coupling portions 210 and 220 are formed. Since the length of the other side 100b is reduced, the main body 100 can be bent based on the third coupling portion 230. For example, when viewed from the end, the main body 100 may be bent into a V-shape (see the shape of the upper and lower ends of the main body 100).

Meanwhile, the first and second coupling portions 210 and 220 may couple the first member 110 and the second member 120 using, for example, adhesive or stitching, but are not necessarily limited thereto.

Figure 8 is a plan view of an airbag structure according to a third embodiment of the present invention, and Figure 9 is a perspective view of an airbag structure according to a third embodiment of the present invention.

Basically, when the main body 100 of the airbag structure according to the second embodiment, the plurality of first coupling parts 210, and the plurality of second coupling parts 220 are defined as the airbag module 400, the third The airbag structure according to the embodiment includes a basic module 500 formed by sequentially arranging a plurality of airbag modules 400 (see FIG. 8). At this time, the basic module 500 has a plurality of airbag modules 400 arranged sequentially and side by side. Accordingly, one side 100a of the main body 100 of one airbag module 400 may be the other side 100b of the main body 100 of another airbag module 400. For example, the basic module 500 may be formed by two airbag modules 400 arranged in succession, but the basic module 500 is not limited to this, and the basic module 500 may be formed of three or more airbag modules 400 in consideration of the overall size of the airbag structure. The airbag modules 400 may be formed by being continuously arranged. At this time, the first coupling portion 210 formed on one side 100a of the main body 100 of one airbag module 400 and the first coupling portion 210 formed on the other side 100b of the main body 100 of the other airbag module 400. The two coupling portions 220 may be formed at positions corresponding to each other.

Meanwhile, a first flow path 510 may be formed so that the plurality of airbag modules 400 communicate fluidly with each other. Accordingly, when fluid is injected into the basic module 500, the fluid is injected into the main body 100 of the plurality of airbag modules 400, and accordingly, the first predetermined space 310 and the second predetermined space 310 of each main body 100 Fluid may be injected into the predetermined space 320. When fluid is injected into the first and second predetermined spaces 310 and 320 of each main body 100, the first and second predetermined spaces 310 and 320, excluding the first and second coupling portions 210 and 220, expand. As a result, it becomes a three-dimensional shape, and when viewed based on the cross section (see FIG. 7), the main body 100 and the first and second members 110 and 120 in the first and second predetermined spaces 310 and 320 are curved from straight lines. changes to Accordingly, as shown in FIG. 9, the length of one side 100a and the other side 100b of each main body 100 is reduced, and the main body 100 has one side 100a and the other side 100b. It can be bent in the vertical direction of the virtual line (V) connecting.

Meanwhile, when the basic module 500 is worn on the wearer's waist, the basic module 500 may be curved in an arc shape when viewed along the longitudinal direction of the main body 100 so as to surround the waist (see reference line (X) in FIG. 9). Since the basic module 500 is bent into an arc shape when looking at the longitudinal direction of the main body 100 as an axis, when fluid is injected into the basic module 500, each main body 100 changes the basic module 500 into an arc shape. (At this time, the direction in which the main body 100 is bent is the vertical direction of the virtual line (V) connecting one side (100a) and the other side (100b) of the main body 100. possible). In this way, as the main body 100 is bent, the main body 100 can implement a three-dimensional shape that wraps around the buttocks.

Meanwhile, between one side 100a and the other side 100b of each main body 100 (the center of the main body 100), a first member 110 and a second member are formed along the longitudinal direction of the main body 100. A third coupling portion 230 that couples 120 may be formed. Therefore, when fluid is injected into each main body 100, the third coupling portion 230 does not decrease in length, and one side (100a) of the main body 100 where the first and second coupling portions 210 and 220 are formed. ) and the other side surface 100b are reduced in length, so each main body 100 can be bent based on the third coupling portion 230. For example, when viewed from the end, each main body 100 may be bent into a V-shape, and accordingly, the basic module 500 on which the airbag modules 400 are continuously arranged may have a continuous V-shape. (refer to the shape of the upper and lower ends of the main body 100). In this way, since each main body 100 is bent based on the third coupling portion 230, each main body 100 is spaced a certain distance away from the wearer's human body and there is a space between each main body 100 and the wearer's human body. A space can be formed, thereby absorbing shock more effectively.

As shown in FIG. 8, the airbag structure according to the third embodiment may further include side modules 600 respectively connected to both sides of the basic module 500. Here, the side module 600 serves to protect the wearer's hip joint. An injection port 650 to which a fluid supply means for supplying fluid is connected may be formed on one side of the side module 600. The fluid supply means may be an inflator in which high-pressure gas is stored. Accordingly, when the control unit detects the wearer's fall, etc., the fluid supply means can supply fluid to the side module 600 through the inlet 650. Additionally, the side module 600 may be formed with a second flow path 610 to communicate fluidly with the basic module 500. Accordingly, when fluid is injected into the side module 600, fluid may also be injected into the basic module 500 through the second flow path 610. At this time, the second flow path 610 for fluid communication between the side module 600 and the basic module 500 may be formed at a position corresponding to the first flow path 510 for fluid communication between the plurality of airbag modules 400. there is. Additionally, a third flow path 235 through which fluid passes is formed in the third coupling portion 230. The third flow path 235 may be formed at a position corresponding to the first and second flow paths. In this way, the first, second, and third flow paths 510, 610, and 235 are formed at positions corresponding to each other, so when fluid is injected from the fluid supply means into the side module 600, the fluid flows into the first flow path arranged in a straight line. ,2,3 It can quickly pass through the flow paths 510, 610, and 235, and can be uniformly supplied to each main body 100 of the basic module 500 at almost the same pressure.

Specifically, one of the two side modules 600 is a first predetermined space 310 of one of the plurality of first predetermined spaces 310 of the basic module 500, and a first combination of two adjacent first predetermined spaces 310. (between the parts 210), and the other side module 600 is connected to a second predetermined space 320 of one of the plurality of second predetermined spaces 320 of the basic module 500, and two adjacent second predetermined spaces 320 are connected to each other. It can be connected to (between parts 220). Accordingly, the second flow path 610 is located in one of the first predetermined spaces 310 of the plurality of first predetermined spaces 310 and the second predetermined space 320 of the plurality of second predetermined spaces 320. can be formed.

As described above, when fluid is injected into the basic module 500 through the side module 600, the fluid injected into the injection port 650 moves across the interior of the side module 600. Here, the side module is formed when the third member and the fourth member are combined to form a space inside (the third member and the fourth member are formed integrally with the first member 110 and the second member 120, respectively). possible), the side module 600 has an auxiliary coupling part ( 620) can be formed. At this time, the auxiliary coupling portion 620 may extend a predetermined length from one side (upper side) and the other side (lower side) of the side module 600 into the interior of the side module 600. Additionally, a plurality of auxiliary coupling portions 620 may be formed and arranged side by side. This auxiliary coupling part 620 divides the interior of the side module 600 into a plurality of spaces, so that noise generated due to the explosion of gunpowder in the fluid supply means (inflator) is divided into the plurality of auxiliary coupling parts 620. It can be reduced step by step as it passes through the space. Ultimately, the noise generated due to the explosion of gunpowder, etc. can be effectively reduced through the auxiliary coupling part 620.

Meanwhile, a fourth flow path 625 is formed between the auxiliary coupling part 620 extending from one side (upper side) of the side module 600 and the auxiliary coupling part 620 extending from the other side (lower side) of the side module 600. can be formed. At this time, the fourth flow path 625 may be formed at a position corresponding to the first, second, and third flow paths 510, 610, and 235. In this way, the first, second, third, and fourth flow paths (510, 610, 235, and 625) are formed at positions corresponding to each other, so when fluid is injected from the fluid supply means into the side module 600, the fluid flows in a straight line. It can quickly pass through the 1st, 2nd, 3rd, and 4th flow paths (510, 610, 235, and 625).

In the above-described basic module, the main body 100 is bent to protect the wearer's buttocks, and the side module 600 can protect the wearer's hip joints. Therefore, the airbag structure according to this embodiment can stably protect the wearer's lower body in the event of a fall.

Meanwhile, the manufacturing method of the airbag structure according to the present invention is not particularly limited, but includes, for example, seam sealing method (seam tape adhesion and then sewing), TPU film method (sealing with thermoplastic polyurethane film), or OPW (One Piece Woven ) method, etc. can be produced by all types of known manufacturing methods.

In addition, in the above description, the airbag structure according to the present invention has been described as being used in a wearable airbag, but it is not limited to this and can be used in all types of airbags, including vehicle airbags.

Although the present invention has been described in detail through specific examples, this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and can be understood by those skilled in the art within the technical spirit of the present invention. It is clear that modifications and improvements are possible.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
