When adding reference numerals to the elements of each of the accompanying drawings herein, it should be noted that the same elements are represented by the same reference numerals as much as possible, even if they are shown in different drawings. In addition, although the terms "first", "second" etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish an element from other elements. In the specification of the present disclosure, when it is believed that the detailed explanation of the relevant technology may unnecessarily obscure the essence of the present disclosure, the detailed explanation of the relevant technology is omitted.

[0040] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0041] Figure 1 is a perspective view showing a helmet fitting system according to an embodiment of the present disclosure. Figure 2 is an exploded perspective view showing a helmet fitting system according to an embodiment of the present disclosure. Figure 3aand Figure 3b is an exploded perspective view showing a fitting portion and an adjustment device of a helmet fitting system according to an embodiment of the present invention.

[0042] like Figure 1 As shown in FIG3 , the helmet fitting system according to the present embodiment includes a strap (100) having one end fixed to a specific point (X) of the helmet (10), a fitting portion (200) connected to the strap (100) and configured to provide elastic force to the back of the wearer's head, and an adjustment device (300) configured to adjust the elastic force of the fitting portion (200).

[0043] The strap (100) is supported on the fitting portion and one end is fixed to a specific point (X) of the helmet (10) (see Figure 1 ), and the other end passes through an elastic device (215) (see Figure 3a ) is connected to the matching device (200). A pair of straps (100) are provided and fixed on both sides of the helmet (10). Specifically, the strap (100) may include a first strap (100a) and a second strap (100b), one end of the first strap (100a) being fixed to one side of the helmet (10), and one end of the second strap (100b) being fixed to the other side of the helmet (10) (see Figure 1 and Figure 2). For example, one end of the first strap (100a) can be fixed to the inner side of the left side of the helmet (10) facing the wearer's head, and one end of the second strap (100b) can be fixed to the inner side of the right side of the helmet (10) facing the wearer's head. In this case, one end of the first strap (100a) and one end of the second strap (100b) can be fixed at opposite positions. In addition, one end of the first strap (100a) and one end of the second strap (100b) do not have to be fixed only to the fixed position of the helmet (10), and can also be fixed to the helmet (10) at two or more points at different distances from the matching portion (200). That is, two or more points at different distances from the matching portion (200) are set on the inner side of the helmet (10), and each of the first strap (100a) and the second strap (100b) are coupled at one of the two or more points. For example, when the first strap (100a) and the second strap (100b) are coupled at a point relatively far from the fitting portion (200), the fitting portion (200) can be located at a relatively forward position due to the first strap (100a) and the second strap (100b). On the contrary, when the first strap (100a) and the second strap (100b) are coupled at a point relatively close to the fitting portion (200), the fitting portion (200) can be located at a relatively backward position due to the first strap (100a) and the second strap (100b). In this way, when the position of the fitting portion (200) changes according to the point at which the first strap (100a) and the second strap (100b) are coupled to the helmet (10), the elastic force provided from the fitting portion (200) toward the back of the head may also change. In addition, the method of coupling the first strap (100a) and the second strap (100b) to the helmet (10) is not particularly limited, but the first protrusion (105a) and the second protrusion (105b) may protrude from one end of the first strap (100a) and one end of the second strap (100b), respectively, and two or more recessed first fastening holes (107a) and two or more recessed second fastening holes (107b) may be provided on the inner side of the helmet (10), the first protrusion (105a) being inserted into the first fastening hole (107a), and the second protrusion (105b) being inserted into the second fastening hole (107b). In this case, the first protrusion (105a) and the second protrusion (105b) may be coupled to the first fastening hole (107a) and the second fastening hole (107b) by using a method such as a snap-fit ​​method.

[0044] like Figure 3a and Figure 3bAs shown, the other end of the first strap (100a) can be connected to the elastic device (215) of the first matching device (210a), and the other end of the second strap (100b) can be connected to the elastic device (215) of the second matching device (210b). As a result, since one end of each of the first strap (100a) and the second strap (100b) is fixed to a specific point (X) of the helmet (10), and the other end of each of the first strap (100a) and the second strap (100b) is connected to the matching portion (200) through the elastic device (215) (see Figure 3a and Figure 3b ), so that an elastic force can be provided from the fitting portion (200) toward the back of the wearer's head, which will be described in detail below.

[0045] A fitting part (200) for providing a fit feeling to the wearer is connected to the strap (100) to provide elastic force toward the back of the wearer's head. Basically, the fitting part (200) can be connected to a first strap (100a) and a second strap (100b) respectively fixed to a specific point (X) of the helmet (10), and can also be connected to a third strap (110) fixed to the back side of the helmet (10). Figure 3a and Figure 3b As shown, the fitting part (200) may include two fitting devices (210) and a contact member (220). The fitting device (210) may be connected to the strap (100) to provide elastic force to the strap (100), and the contact member (220) is arranged so that the two fitting devices are movable inside the contact member (220), and the contact member is in contact with the back of the wearer's head. For example, the contact member (220) may have a receiving space therein, and the two fitting devices (210) may be arranged in the receiving space of the contact member (220) to slide along the longitudinal direction of the contact member (220).

[0046] Specifically, the matching device (210) may include an elastic device (215) and a support portion (217). The elastic device (215) is directly connected to the strap to substantially provide elastic force to the strap (100). In addition, the support portion (217) may be formed to accommodate the elastic device (215) therein, and the elastic device (215) may be stretched or shortened inside the support portion (217). In this case, one end of the elastic device (215) may be connected to a first coupling portion (109) formed at the other end of the strap (100), and the other end of the elastic device (215) may be connected to a second coupling portion (218) formed at one end of the support portion (217). In this way, one end of the elastic device (215) may be connected to the first coupling portion (109) of the strap (100), and the other end of the elastic device (215) may be connected to the second coupling portion (218) of the support portion (217), so that the elastic force of the elastic device (215) is provided to the strap (100). Herein, the elastic device (215) is not particularly limited as long as it can provide elastic force, but may be, for example, a tension spring. However, this is only an example, and the elastic device (215) may be a belt, rubber or silicone.

[0047] The adjusting device (300) for adjusting the elastic force of the fitting portion (200) can change the position of the fitting device (210, the supporting portion (217)) relative to the specific point (X) to which the strap (100) of the helmet (10) is fixed. Specifically, Figure 4a and Figure 4b As shown in FIG. 1 , as the adjusting device (300) moves the matching device (210, the supporting portion (217)) away from the specific point (X), the tensile force applied to the elastic device (215) increases, and the elastic device (215) of the matching device (210) is relatively stretched, thereby increasing the elastic force. In this way, when the elastic force of the matching device (210, the elastic device (215)) increases, the elastic force provided to the strap (100) increases, and thus, finally Figure 5 As shown, the pressure applied by the fitting portion (200) to the back of the wearer's head will increase. Figure 6a and 6b As shown, when the adjusting device (300) moves the matching device (210, the supporting portion (217)) closer to the specific point (X), the tensile force applied to the elastic device (215) is reduced, and the elastic device (215) of the matching device (210) is relatively shortened, thereby reducing the elastic force. In this way, when the elastic force of the matching device (210, the elastic device (215)) is reduced, the elastic force provided to the belt (100) is reduced, and finally as shown in FIG. Figure 7As shown, the pressure applied by the fitting part (200) to the back of the wearer's head is reduced. Therefore, the pressure applied by the fitting part (200) to the back of the wearer's head can be adjusted by changing the position of the fitting device (210) using the adjustment device (300).

[0048] The adjustment device (300) may be rotatably coupled to the holder (225) of the contact member (220) (see Figure 3a ), and can be gear-coupled to the support portion (217) of the mating device (210) (see Figure 4a ). For example, a pinion (310) may be formed on the adjustment device (300), a rack (219) may be formed on the support portion (217) of the matching device (210), and the pinion (310) of the adjustment device (300) and the rack (219) of the support portion (217) may be gear-coupled to each other. Accordingly, when the adjustment device (300) rotates, the support portion (217) of the matching device (210) may move relative to the contact member (220) accordingly. In this way, when the support portion (217) of the matching device (210) moves, the elastic force of the elastic device (215) changes, and the pressure applied to the back of the head by the contact member (220) can be adjusted.

[0049] like Figure 3a and Figure 3b As shown, the adjustment device (300) may further include a latch portion (320) extending from the pinion (310), a gear portion (330) formed on the contact member (220) (holder (225)) to be coupled to the latch portion (320), and an operating portion (340) coupled to the latch portion (320) to rotate the latch portion (320). Basically, the latch portion (320) may be coupled to the gear portion (330), and then the pinion (310) may be stopped from rotating arbitrarily, so that the support portion (217) of the matching device (210) is also stopped at a fixed position. However, when the wearer rotates the operating portion (340), the latch portion (320) and the pinion (310) may rotate together, and therefore, the support portion (217) of the matching device (210) may rotate relative to the contact member (220).

[0050] Invention method

[0051] As described above, since the strap (100) may include a first strap (100a) and a second strap (100b), the matching device (210) may also include a first matching device (210a) and a second matching device (210b). The other end of the first strap (100a) may be connected to the elastic device (215) of the first matching device (210a), and the other end of the second strap (100b) may be connected to the elastic device (215) of the second matching device (210b).

[0052] like Figure 4a As shown, the adjustment device (300) can be gear-coupled to the first matching device (210a) and the second matching device (210b). For example, the first matching device (210a) and the second matching device (210b) can overlap each other in a direction perpendicular to the elastic force provided by the matching device (210) (up and down direction). In this case, the pinion (310) of the adjustment device (300) can be located between the first matching device (210a) and the second matching device (210b). Accordingly, the pinion (310) of the adjustment device (300) can be gear-coupled to the rack (219) of the first matching device (210a) and the rack (219) of the second matching device (210b) at the same time. Therefore, when the pinion (210) rotates, the first matching device (210a) and the second matching device (210b) gear-coupled to the pinion (310) will move simultaneously.

[0053] Will refer to Figure 3a and Figure 3b The contact member (220) is described in more detail. The contact member (220) may include a base portion (221) and a cover portion (223) coupled to the base portion (221). In this case, there may be a receiving space inside the base portion (221) and the cover portion (223), and the support portion (217) of the mating device (210) may move while sliding in the receiving space. One surface of the support portion (217) of the mating device (210) may contact one surface of the base portion (221). Accordingly, in order to allow one surface of the support portion (217) of the mating device (210) to slide smoothly along one surface of the base portion (221), one surface of the support portion (217) of the mating device (210) may extend to have a curved surface corresponding to the curved surface of one surface of the base portion (221). Furthermore, in order to guide the sliding of the support portion (217) of the matching device (210), a guide portion (222) protruding along the sliding direction of the support portion (217) of the matching device (210) may be formed on one surface of the base portion (221) (see Figure 3a ).

[0054] In addition, a retainer (225) may be provided on the contact member (220). The retainer (225) may be coupled to the base portion (221) of the contact member (220), and may surround the first mating device (210a) and the second mating device (210b) to expose one side (one end) of each of the first mating device (210a) and the second mating device (210b). For example, the retainer (225) may be formed as a ' ' shape to surround the first mating device (210a) and the second mating device (210b), and openings (225) may be formed on both sides of the retainer (225) to expose one side (one end) of each of the first mating device (210a) and the second mating device (210b). In addition, a fastening hole (225b) may be formed on one side (rear side) of the retainer (225), and the pinion (310) of the adjustment device (300) may be rotatably coupled to the fastening hole (225b).

[0055] The retainer (225) can be used in a method for manufacturing a helmet fitting system according to an embodiment of the present disclosure. The method for manufacturing a helmet fitting system according to an embodiment of the present disclosure will be described in detail. First, as Figure 8 As shown, the retainer (225) is coupled to the base portion (221). Then, as shown in Fig. 9 As shown, the first mating device (210a) and the second mating device (210b) are inserted into the retainer (225) through the openings (225a) formed on both sides of the retainer (225). Then, as shown in FIG. Fig.10 As shown, the adjusting device (300) is coupled to the fastening hole (225b) of the retainer (225), and the pinion (310) of the adjusting device (300) is gear-coupled to the rack (219) of the first mating device and the second mating device (210a) (210b). In this case, since one side (one end) of each of the first mating device and the second mating device (210a) (210b) is exposed from the retainer (225), the assembler can check the position of the first mating device (210a) and the second mating device (210b), and when the first mating device (210a) and the second mating device (210b) are in the correct position, the pinion (310) of the adjusting device (300) can be coupled to the rack (219) of the first mating device and the second mating device (210a) (210b).

[0056] In addition, if Figure 1 and Figure 2As shown, the strap (100) may further include a third strap (110). The third strap (110) may be connected to the fitting portion (200), may extend to the rear inner side of the helmet (10), and may be coupled to the inner side of the helmet (10). According to the movement of the third strap (110), the fitting portion (200) may move forward or backward relative to the helmet (10). In this case, the third strap (110) may be coupled to a fastening portion (130) formed on the inner side of the helmet (10) (see Figure 2 Specifically, the uneven portion (120) may be continuously formed on both side surfaces of the third strap (110), and the uneven portion (120) may be coupled to a fastening portion (130) provided on the helmet (10), so that the third strap (110) is fixed at a specific position.

[0057] In the helmet fitting system according to the prior art, an uneven portion is formed on the bottom surface of the strap (the element corresponding to the third strap). Accordingly, when the curvature of the strap changes according to the shape of the helmet, the gap between the concave and convex parts of the uneven portion changes, so that the wearer has a different sense of control. In addition, in the helmet fitting system according to the present embodiment, since an elastic force is applied to the fitting part (200), the curvature change of the third strap (110) becomes more significant. However, in the helmet fitting system according to the present embodiment, since the uneven portion (120) is formed on both side surfaces of the third strap (110), the gap between the concave and convex parts of the uneven portion (120) hardly changes according to the change in the curvature of the third strap (110), so that the wearer's sense of control is maintained at a constant level.

[0058] As described above, since the fitting part (200) is connected to the first strap (100a) and the second strap (100b) by the elastic means (215), an elastic force can be provided to the back of the wearer's head. Accordingly, whenever the wearer puts on or takes off the helmet (10), the elastic means of the first fitting means (210a) and the second fitting means (210b) can be stretched, and the fitting part (200) can be moved backward. Therefore, the wearer can simply put on and take off the helmet (10) without separate operations. In addition, since an elastic force is provided from the fitting part (200) to the back of the wearer's head when the wearer puts on the helmet (10), the contact member (220) of the fitting part (200) can contact the back of the wearer's head, thereby preventing the helmet from being arbitrarily taken off, and providing a comfortable fit to the wearer.

[0059] Furthermore, by using the adjustment device (300) the fitting device (210, support portion (217)) is moved away from the specific point (X) to which the strap (100) of the helmet (10) is fixed (see Figure 4a and Figure 4b ), the elastic force of the fitting device (210, support portion (217)) will increase, and the elastic force applied by the fitting portion (200, contact member (220)) to the back of the wearer's head will increase. Conversely, by using the adjustment device (300) to move the fitting device (210, support portion (217)) closer to the specific point (X) to which the strap (100) of the helmet (10) is fixed (see Figure 6a and Figure 6b ), the elastic force of the matching device (210, elastic device (215)) will be reduced, and the elastic force applied by the matching portion (200, contact member (220)) to the back of the wearer's head will be reduced. Therefore, the wearer can adjust the elastic force of the matching device (210, elastic device (215)) by operating the adjustment device (300) to provide various elastic forces (pressures) required by the wearer.

[0060] Although the present disclosure has been described in detail with reference to specific exemplary embodiments for specifically explaining the present disclosure, the present disclosure is not limited to the exemplary embodiments and may obviously be modified or altered by those skilled in the art without departing from the technical spirit of the present disclosure.

[0061] Simple modifications and changes to the present disclosure all belong to the scope of the present disclosure, and the specific protection scope of the present disclosure can be clearly defined by the appended claims.
