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. 9, 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 the 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, it is difficult to fold. Additionally, design is difficult because a planar development (2D) must be constructed from a three-dimensional shape (3D). In addition, there is a problem that there is a lot of remaining space between the edge and the surface on the planar development (2D), so the material consumption is high and the manufacturing cost increases accordingly.

1 to 3 are plan views of an airbag structure according to a first embodiment of the present invention.

As shown in FIGS. 1 to 3, the airbag structure according to the first embodiment includes a main body 100 into which fluid is injected and a plurality of predetermined points A spaced apart from each other along the longitudinal direction are disposed on the side, and Fluid is injected from the main body 100, and includes a protrusion 200 extending in a direction away from the main body 100 from two adjacent predetermined points A, and the protrusion 200 is one end connected to the main body 100. The width of the other end furthest from the main body 100 is smaller than the width.

The main body 100 is expanded by injecting fluid from a fluid supply means. For example, an injection port connected to a fluid supply means may be formed on one side of the main body 100. At this time, the fluid supply means may be an inflator storing high-pressure gas, and the main body 100 may be used as a wearable airbag. In this case, when the control unit detects the wearer's fall, etc., the fluid supply means can supply fluid to the main body 100 through the injection port. Additionally, a protrusion 200 extends from the main body 100, and the protrusion 200 is in fluid communication with the main body 100. Accordingly, when fluid is injected into the main body 100, the fluid is also injected into the protrusion 200 through the main body 100, so that the main body 100 and the protrusion 200 can be expanded together. Overall, 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. 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 protrusion 200, and specific details regarding this will be described later.

The protrusion 200 is expanded by injecting fluid from the main body 100. Here, the protrusion 200 extends from the side of the main body 100 in a direction away from the main body 100 to communicate fluidly with the main body 100. As described above, a plurality of predetermined points (A) are disposed on the side of the main body 100, spaced apart from each other along the longitudinal direction. Among these plural predetermined points (A), two adjacent predetermined points (A) are provided with protrusions ( 200) extends in a direction away from the main body 100. That is, the two adjacent predetermined points A are the starting points of the protrusion 200, and the protrusion 200 extends in a direction away from the two adjacent predetermined points A. At this time, the width of the other end of the protrusion 200 furthest from the main body 100 is smaller than the width of one end connected to the main body 100. That is, the width of the other end of the protrusion 200 that protrudes the most is smaller than the width of one end of the protrusion 200 that contacts the main body 100. For example, the width of the protrusion 200 may decrease from one end connected to the main body 100 to the other end that protrudes the most from the main body 100. Specifically, the shape of the protrusion 200 is not particularly limited, but may be arc-shaped (see FIG. 1), square (see FIG. 2), or triangle (see FIG. 3).

As described above, the width of the other end (the end furthest from the main body 100) of the protrusion 200 is smaller than the width of one end (the end connected to the main body 100) (as shown in FIG. 1, the protrusion 200 ) If the shape is arc-shaped, the width of the other end furthest from the main body 100 may actually converge to 0). Accordingly, when fluid is injected into the protrusion 200, the width of one end of the protrusion 200 decreases. Specifically, as shown in the enlarged view of FIG. 1, when fluid is injected into the protrusion 200, the width (distance between predetermined points A) of the protrusion 200 is reduced (W->D). For example, when fluid is injected into the protrusion 200, the protrusion 200, which was initially a two-dimensional shape, becomes a three-dimensional shape such as a hemisphere or a cone, and the curvature of the protrusion 200 increases, and the width of one end of the protrusion 200 increases. This can be reduced (W->D).

As shown in FIG. 4, assuming that the curvature of the protrusion 200 before the fluid is injected is very small (assuming that the radius of curvature of the protrusion 200 is very large), one end of the protrusion 200 before the fluid is injected The width (L) can be assumed to be equal to the distance (W) between predetermined points (A) in the two-dimensional shape (L=W). Meanwhile, after the fluid is injected, the protrusion 200 takes on a three-dimensional shape such as a hemisphere or a cone, and the width (L') of one end of the protrusion 200 is reduced to L'=D=2W/π.

Therefore, the change in the width of one end of the protrusion 200 is expressed as ΔL=L'-L=(2/π-1)*W, and the maximum change in the width of one end of the protrusion 200 assuming a hemisphere is ΔL _max ≒- With W/3 (│ΔL _max │≒W/3), the width (L') of one end of the protrusion 200 after fluid injection is approximately 2/3 times the width (L) of one end of the protrusion 200 before fluid injection. decreases.

For reference, the amount of change in the width of one end of the protrusion 200 may be adjusted depending on the thickness of the protrusion 200 (degree of protrusion from the main body 100), the distance between predetermined points A, etc.

As described above, when fluid is injected into each protrusion 200 through the main body 100, the width of one end of each protrusion 200 is reduced, and the side of the main body 100 where a plurality of protrusions 200 are formed. The length of can be reduced overall. Accordingly, since the length of one side of the main body 100 on which the protrusion 200 is formed is shorter than the length of the other side of the main body 100, the main body 100 may be bent in the direction in which the protrusion 200 is formed.

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 FIGS. 5 and 6, the airbag structure according to the second embodiment includes a first body into which fluid is injected and a plurality of first predetermined points A1 spaced apart from each other are arranged on one side along the longitudinal direction ( 110), a fluid is injected from the first body 110, and a first protrusion 210 extending in a direction away from one side of the first body 110 from two adjacent first predetermined points A1, the fluid is injected. The second body 120 is arranged in parallel with the first body 110 and has a plurality of second predetermined points A2 spaced apart from each other on one side along the longitudinal direction, and the fluid flows from the second body 120. The second protrusion 220 is injected and extends in a direction away from one side of the second main body 120 from two adjacent second predetermined points A2, and between the first main body 110 and the second main body 120. It includes a connection part 300 formed in, and the first protrusion 210 has a width of the other end furthest from the first main body 110 smaller than the width of one end connected to the first main body 110, and the second protrusion 220 ) has a width of the other end furthest from the second main body 120 than the width of one end connected to the second main body 120.

While the airbag structure according to the first embodiment has a protrusion 200 formed on the side of one body 100, the airbag structure according to the second embodiment has two bodies (first and second bodies 110, 120)), a protrusion (first and second protrusions 210, 220) is formed on one side, respectively, and the two bodies (first and second main bodies 110, 120) are connected by a connection portion 300. do. Accordingly, the airbag structure according to the second embodiment will be described focusing on the differences with the airbag structure according to the first embodiment, omitting overlapping content.

The airbag structure according to the second embodiment includes first and second bodies 110 and 120 arranged side by side with each other. Here, the first and second bodies 110 and 120 may be expanded by injecting fluid. In addition, since the first protrusion 210 extends from the first body 110 and the second protrusion 220 extends from the second body 120, fluid is injected into the first and second bodies 110 and 120. When this happens, fluid is also injected into the first and second protrusions 210 and 220, so that the first and second main bodies 110 and 120 and the first and second protrusions 210 and 220 can be expanded together. Overall, the first and second bodies 110 and 120 may extend long in one direction. At this time, a plurality of first predetermined points A1 spaced apart from each other along the longitudinal direction are disposed on one side of the first main body 110, and a plurality of first predetermined points A1 spaced apart from each other along the longitudinal direction are disposed on one side of the second main body 120. 2 A predetermined point (A2) can be placed. Specifically, one side of the first body 110 may be a side far away from the second body 120, and one side of the second body 120 may be a side far away from the first body 110. Ultimately, a plurality of first predetermined points A1 are formed on the side of the first main body 110 far away from the second main body 120, and a plurality of second predetermined points A2 are formed on the side of the first main body 110 and the second main body 120. It may be formed on a side of the second main body 120 that is far away. The first plurality of predetermined points A1 is the starting point of the first protrusion 210, and the second plurality of predetermined points A2 is the starting point of the second protrusion 220, so that the first protrusion 210 may be formed on the side of the first main body 110 that is far away from the second main body 120, and the second protrusion 220 may be formed on the side of the second main body 120 that is far away from the first main body 110. there is.

Here, the first and second protrusions 210 and 220 are expanded by injecting fluid from the first and second bodies 110 and 120, and are in fluid communication with the first and second bodies 110 and 120. It extends from one side of the main bodies 110 and 120 in a direction away from the first and second main bodies 110 and 120. As described above, a plurality of first predetermined points A1 are disposed on one side of the first body 110 and spaced apart from each other along the longitudinal direction. Among these plural first predetermined points A1, two adjacent first predetermined points A1 are disposed on one side of the first body 110. The first protrusion 210 extends from the predetermined point A1 in a direction away from the first body 110. Similarly, a plurality of second predetermined points A2 are disposed on one side of the second body 120 and spaced apart from each other along the longitudinal direction. Among these plural second predetermined points A2, two adjacent second predetermined points A2 are disposed. From point A2, the second protrusion 220 extends in a direction away from the second body 120. At this time, the width of the other end of the first and second protrusions 210 and 220 furthest from the first and second main bodies 110 and 120 is smaller than the width of one end connected to the first and second main bodies 110 and 120. For example, the width of the first and second protrusions 210 and 220 decreases from one end connected to the first and second bodies 110 and 120 to the other end that protrudes the most from the first and second bodies 110 and 120. can do.

Accordingly, when fluid is injected into the first and second protrusions 210 and 220, the width of one end of the first and second protrusions 210 and 220 is reduced, and as a result, a plurality of first and second protrusions 210 and 220 are formed. The overall length of one side of the formed first and second bodies 110 and 120 may be reduced. Ultimately, the length of one side of the first and second main bodies 110 and 120 on which the first and second protrusions 210 and 220 are formed is equal to the length of the other side of the first and second main bodies 110 and 120 (the side connected to the connection portion 300). Since it is shorter than the length, the first and second bodies 110 and 120 and the connecting portion 300 are aligned in the vertical direction of the imaginary line (V) connecting one side of the first body 110 and one side of the second body 120. It can bend. That is, since the first and second protrusions 210 and 220 are formed on one side of the first and second main bodies 110 and 120, respectively, the first and second main bodies 110 and 120 and the connection portion 300 are connected to the first main body (110, 120). It is not bent in the direction of the first protrusion 210 formed on one side of the second body 110, or is not bent in the direction of the second protrusion 220 formed on one side of the second body 120, but is bent in a third direction (for example, a connection part It can be bent in a direction perpendicular to one side of 300 (forward), see arrow in FIG. 6). Meanwhile, an expansion part 135 may be provided at one end of the first and second bodies 110 and 120 and the connection part 300. Here, the expansion part 135 is in fluid communication with the first and second bodies 110 and 120 and the connection part 300, and the first and second bodies 110 and 120 and the connection part 300 are connected through the expansion part 135. Fluid may be injected. At this time, the expansion part 135 may be placed on the wearer's waist. Therefore, when inflated, the expansion part 135 can protect the wearer's waist, and the first and second bodies 110 and 120 and the connection part 300 can protect the wearer's buttocks.

Figure 7 is a plan view of an airbag structure according to a third embodiment of the present invention, and Figure 8 is a perspective view of an airbag structure according to a third embodiment of the present invention.

Basically, the airbag structure according to the third embodiment is a third body 130 and a third protrusion 230 added to the airbag structure according to the second embodiment. Accordingly, the airbag structure according to the third embodiment will be described focusing on the third body 130 and the third protrusion 230, with overlapping content with the airbag structure according to the second embodiment omitted.

The third body 130 of the airbag structure according to the third embodiment may be inflated by injecting fluid. In addition, since the third protrusion 230 extends from the third main body 130, when fluid is injected into the third main body 130, the fluid is also injected into the third protrusion 230, and the third main body 130 and The third protrusion 230 may be expanded together. Meanwhile, the third body 130 extends vertically from the end (top) of the first and second bodies 110 and 120 and the connection portion 300, and the first and second bodies 110 and 120 and the connection portion 300 Since fluid is in fluid communication with the third body 130, fluid can also be injected into the first and second bodies 110 and 120 and the connection portion 300 to expand. Overall, the third body 130 may extend long in one direction. At this time, a plurality of third predetermined points A3 spaced apart from each other along the longitudinal direction may be disposed on one side of the third main body 130. Specifically, one side of the third body 130 may be a side far away from the first and second bodies 110 and 120 and the connection portion 300. Ultimately, a plurality of third predetermined points A3 may be formed on the side of the third body 130 that is far from the first and second bodies 110 and 120 and the connection portion 300. Since the plurality of third predetermined points A3 are the starting points of the third protrusion 230, the third protrusion 230 is located at a distance from the first and second main bodies 110 and 120 and the connection part 300. It may be formed on the side of (130).

Here, the third protrusion 230 is expanded by injecting fluid from the third body 130, and is provided from one side of the third body 130 to communicate fluidly with the third body 130. extends in the direction away from you. As described above, a plurality of third predetermined points A3 are disposed on one side of the third body 130 and spaced apart from each other along the longitudinal direction. Among these plural third predetermined points A3, two adjacent third predetermined points A3 are disposed on one side of the third main body 130. The third protrusion 230 extends from the predetermined point A3 in a direction away from the third main body 130. At this time, the width of the other end of the third protrusion 230 furthest from the third body 130 is smaller than the width of the end connected to the third body 130. For example, the width of the third protrusion 230 may decrease from one end connected to the third body 130 to the other end that protrudes the most from the third body 130.

Therefore, when fluid is injected into the third protrusion 230, the width of one end of the third protrusion 230 is reduced, and as a result, the length of one side of the third body 130 on which the plurality of third protrusions 230 are formed is may be reduced overall. Ultimately, the length of one side of the third body 130 on which the third protrusion 230 is formed is shorter than that of the other side of the third body 130 (the side closest to the first and second bodies 110 and 120 and the connection portion 300). Because it is shorter than the length, the third body 130 may be bent. In this way, when the third body 130 is bent, the third body 130 can implement a three-dimensional shape corresponding to the wearer's waist.

Meanwhile, when fluid is injected into each of the first and second protrusions 210 and 220 through the first and second bodies 110 and 120, the width of one end of each of the first and second protrusions 210 and 220 is reduced. , the overall length of one side of the first and second bodies 110 and 120 on which the plurality of first and second protrusions 210 and 220 are formed may be reduced. Accordingly, the length of one side of the first and second bodies 110 and 120 on which the first and second protrusions 210 and 220 are formed is the other side of the first and second bodies 110 and 120 (the side connected to the connection portion 300). Since it is shorter than the length of , the first and second bodies 110 and 120 may be bent (see arrow in FIG. 8). In this way, when the first and second bodies 110 and 120 are bent, the first and second bodies 110 and 120 can implement a three-dimensional shape corresponding to the wearer's buttocks.

Ultimately, in the airbag structure according to this embodiment, when fluid is injected, the third body 130 is bent to implement a three-dimensional shape corresponding to the wearer's waist, and at the same time, the first and second bodies 110 and 120 are bent to form a three-dimensional shape corresponding to the wearer's buttocks. A three-dimensional shape corresponding to can be implemented. Therefore, when fluid is injected during a fall, the first, second, and third main bodies (110, 120, 130) and the first, second, and third protrusions (210, 220, and 230) can stably protect the wearer's waist and buttocks. .

Additionally, the airbag structure according to this embodiment may further include an auxiliary expansion unit 140. This auxiliary expansion part 140 extends from the third body 130 (extending from both sides of the third body 130), and may be formed in an annular shape so that one end and the other end are in fluid communication with the third body 130. . Here, the auxiliary expansion part 140 can protect the wearer's pelvis when expanded.

The airbag structure according to the present invention has protrusions 200 or first, second, and third protrusions 210, 220 continuously along the longitudinal direction of the main body 100, or the first, second, and third main bodies 110, 120, and 130. , 230)) is formed, and a three-dimensional shape can be realized by injecting the fluid, so there is no need to implement the three-dimensional shape before injecting the fluid. Therefore, since sewing work to implement a three-dimensional shape is unnecessary, manufacturing time and manufacturing cost can be reduced, and problems with quality differences depending on the operator can be prevented in advance. Additionally, since it has a flat shape before injecting fluid, it is easy to fold. In addition, there is no need to construct a complex planar development (2D) from a three-dimensional shape (3D), making design easy. In addition, since the flat development (2D) is unnecessary, there is no residual space between the edge and the surface on the flat development (2D), thereby preventing unnecessary consumption of material.

Meanwhile, the manufacturing method of the airbag structure according to the present invention is not particularly limited, but for example, seam sealing method (seam tape adhering 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 explaining the present invention in detail, 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.
