Mode for Carrying Out the Invention

[0033] The object, particular advantages, and novel features of the present invention will become even clearer from the following detailed description and preferred embodiments, which are associated with the accompanying drawings. It should be noted that, in this specification, when assigning reference numerals to each component in each drawing, the same component is given the same number whenever possible, even when shown in other drawings. Furthermore, terms such as "first," "second," etc., are used to distinguish one component from another, and the components are not limited by these terms. In describing the present invention, detailed descriptions of related prior art that could obscure the gist of the invention are omitted below.

[0034] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0035] Figure 1 is a perspective view of a helmet fitting system according to an embodiment of the present invention, Figure 2 is an exploded perspective view of a helmet fitting system according to an embodiment of the present invention, and Figures 3a to 3b are exploded perspective views of the fitting section and adjustment means of a helmet fitting system according to an embodiment of the present invention.

[0036] As shown in Figures 1 to 3, the helmet fitting system according to this embodiment includes a band 100, one end of which is fixed to a predetermined point X on the helmet 10; a fitting part 200 connected to the band 100 and which provides elastic force to the back of the wearer's head; and an adjustment means 300 for adjusting the elastic force of the fitting part 200.

[0037] The band 100 is supported by a fitting portion 200, with one end of the band 100 fixed to a predetermined point X (see Figure 1) on the helmet 10, and the other end of the band 100 connected to the fitting portion 200 via an elastic means 215 (see Figure 3a). Overall, the band 100 is provided in a pair and is fixed to both sides of the helmet 10. Specifically, the band 100 may include a first band 100a with one end fixed to one side of the helmet 10, and a second band 100b with one end fixed to the other side of the helmet 10 (see Figures 1 to 2). For example, one end of the first band 100a may be fixed to the inside of the helmet 10 facing the left side of the wearer's head, while one end of the second band 100b may be fixed to the inside of the helmet 10 facing the right side of the wearer's head. In this case, one end of the first band 100a and one end of the second band 100b may be fixed in positions facing each other. Additionally, one end of the first band 100a and one end of the second band 100b do not have to be fixed only to a fixed position on the helmet 10, but can be fixed to the helmet 10 at two or more points at different distances from the fitting section 200. That is, the inside of the helmet 10 is provided with two or more points at different distances from the fitting section 200, and the first band 100a and the second band 100b are connected to one of these points. For example, if the first and second bands 100a and 100b are connected to a point relatively far from the fitting section 200, the fitting section 200 may be positioned relatively forward by the first and second bands 100a and 100b. Conversely, if the first and second bands 100a and 100b are connected to a point relatively close to the fitting section 200, the fitting section 200 may be positioned relatively backward by the first and second bands 100a and 100b. Thus, as the position of the fitting portion 200 moves according to the point where the first and second bands 100a and 100b are joined to the helmet 10, the elastic force provided from the fitting portion 200 toward the back of the head may also change substantially.Furthermore, the method of connecting the first and second bands 100a, 100b to the helmet 10 is not particularly limited, but a first projection 105a and a second projection 105b are formed at one end of the first band 100a and one end of the second band 100b, respectively, and two or more recessed first fastening holes 107a into which the first projection 105a is inserted are provided on the inside of the helmet 10, and two or more recessed second fastening holes 107b into which the second projection 105b is inserted. In this case, the method of connecting the first and second projections 105a, 105b to the first and second fastening holes 107a, 107b may be, for example, a snap method.

[0038] On the other hand, as shown in Figures 3a to 3b, the other end of the first band 100a can be connected to the elastic means 215 of the first fitting means 210a, and the other end of the second band 100b can be connected to the elastic means 215 of the second fitting means 210b. In short, one end of the first and second bands 100a and 100b is fixed to a predetermined point X on the helmet 10 (see Figure 1), and the other ends of the first and second bands 100a and 100b are connected to the fitting part 200 through the elastic means 215 (see Figures 3a to 3b), so that the fitting part 200 can be provided with an elastic force towards the back of the wearer's head, but the specific details related to this will be explained later.

[0039] The fitting section 200 provides the wearer with a sense of fit and is connected to the band 100, providing elastic force toward the back of the wearer's head. Basically, the fitting section 200 is connected to the first and second bands 100a and 100b fixed at a predetermined point X on the helmet 10, and may also be connected to a third band 110 fixed to the rear side of the helmet 10. As shown in Figures 3a to 3b, the fitting section 200 may include two fitting means 210 and a contact section 220. Here, the fitting means 210 is connected to the band 100 and provides elastic force to the band 100, and the contact section 220 has two fitting means 210 movably arranged inside it and contacts the back of the wearer's head. For example, the contact section 220 may have a housing space inside, and the two fitting means 210 may be arranged to slide along the length of the contact section 220 within the housing space of the contact section 220.

[0040] Specifically, the fitting means 210 may include an elastic means 215 and a support portion 217. Here, the elastic means 215 is directly connected to the band 100 and substantially provides elastic force to the band 100. The support portion 217 is formed in a manner that accommodates the elastic means 215 inside, and the elastic means 215 can be stretched or contracted inside the support portion 217. In this case, one end of the elastic means 215 may be connected to a first connecting portion 109 formed at the other end of the band 100, and the other end of the elastic means 215 may be connected to a second connecting portion 218 formed at the end of the support portion 217. In this way, by connecting one end of the elastic means 215 to the first connecting portion 109 of the band 100 and the other end of the elastic means 215 to the second connecting portion 218 of the support portion 217, the elastic force of the elastic means 215 can be provided to the band 100. Here, the elastic means 215 is not particularly limited as long as it can provide elastic force, but for example, it could be a tension spring. However, the fact that the elastic means 215 is a tension spring is illustrative, and the elastic means 215 could also be a band, rubber, silicone, etc.

[0041] The adjustment means 300 is responsible for adjusting the elastic force of the fitting portion 200, and can move the position of the fitting means 210 (support portion 217) relative to a predetermined point X on the helmet 10 to which the band 100 is fixed. Specifically, as shown in Figures 4a to 4b, when the adjustment means 300 moves the fitting means 210 (support portion 217) away from the predetermined point X, the tensile force applied to the elastic means 215 increases, and the elastic means 215 of the fitting means 210 is relatively stretched, potentially increasing its elastic force. In this way, an increase in the elastic force of the fitting means 210 (elastic means 215) increases the elastic force provided to the band 100, and ultimately, as shown in Figure 5, the pressure exerted by the fitting portion 200 on the back of the wearer's head may increase. Conversely, as shown in Figures 6a to 6b, when the adjustment means 300 moves the fitting means 210 (support portion 217) toward a predetermined point X, the tensile force applied to the elastic means 215 decreases, and the elastic means 215 of the fitting means 210 is relatively contracted, potentially reducing its elastic force. In this way, a decrease in the elastic force of the fitting means 210 (elastic means 215) reduces the elastic force provided to the band 100, and ultimately, as shown in Figure 7, the pressure exerted by the fitting portion 200 on the back of the wearer's head may decrease. In short, the pressure exerted by the fitting portion 200 on the back of the wearer's head can be adjusted by moving the position of the fitting means 210 using the adjustment means 300.

[0042] Here, the adjustment means 300 can be rotatably coupled to the holder 225 of the contact portion 220 (see Figure 3a) and can be gear-coupled to the support portion 217 of the fitting means 210 (see Figure 4a). For example, a pinion gear 310 may be formed on the adjustment means 300, and a rack gear 219 may be formed on the support portion 217 of the fitting means 210, and the pinion gear 310 of the adjustment means 300 and the rack gear 219 of the support portion 217 may be gear-coupled. Therefore, when the adjustment means 300 is rotated, the support portion 217 of the fitting means 210 may move relative to the contact portion 220 in response. In this way, as the support portion 217 of the fitting means 210 moves, the elastic force of the elastic means 215 changes, and the pressure applied by the contact portion 220 to the back of the head can be adjusted.

[0043] As shown in Figures 3a to 3b, the adjustment means 300 may further include a latch portion 320 extending from the pinion gear 310, a gear portion 330 formed on the contact portion 220 (holder 225) so as to be coupled with the latch portion 320, and an operating portion 340 coupled to the latch portion 320 for rotating the latch portion 320. Basically, the latch portion 320 is coupled to the gear portion 330, and the pinion gear 310 stops without rotating arbitrarily, so the support portion 217 of the fitting means 210 can also stop in a fixed position. However, if the wearer rotates the operating portion 340, the latch portion 320 and the pinion gear 310 rotate together, causing the support portion 217 of the fitting means 210 to move relative to the contact portion 220.

[0044] [Examples] As described above, since the band 100 may include first and second bands 100a and 100b, the fitting means 210 may also include first and second fitting means 210a and 210b. Here, the other end of the first band 100a may be connected to the elastic means 215 of the first fitting means 210a, and the other end of the second band 100b may be connected to the elastic means 215 of the second fitting means 210b.

[0045] As shown in Figure 4a, the adjustment means 300 can be gear-coupled to the first and second fitting means 210a and 210b. For example, the first fitting means 210a and the second fitting means 210b may be arranged so as to overlap perpendicular to the direction in which the elastic force of the fitting means 210 is provided (vertically). In this case, the pinion gear 310 of the adjustment means 300 may be positioned between the first fitting means 210a and the second fitting means 210b. Thus, the pinion gear 310 of the adjustment means 300 can be gear-coupled simultaneously to the rack gear 219 of the first fitting means 210a and the rack gear 219 of the second fitting means 210b. In short, when the pinion gear 310 rotates, the first and second fitting means 210a and 210b, which are gear-coupled to the pinion gear 310, can move simultaneously.

[0046] On the other hand, referring to Figures 3a to 3b, the contact portion 220 can be described in more detail as follows: The contact portion 220 can include a base portion 221 and a cover portion 223 coupled to the base portion 221. In this case, a housing space is provided inside the base portion 221 and the cover portion 223, and the support portion 217 of the fitting means 210 can move while sliding within this housing space. Here, one surface of the support portion 217 of the fitting means 210 can come into contact with one surface of the base portion 221. Therefore, one surface of the support portion 217 of the fitting means 210 can be extended to have a curvature corresponding to the curvature of one surface of the base portion 221, so that one surface of the support portion 217 of the fitting means 210 can slide smoothly along one surface of the base portion 221. Additionally, a guide portion 222 (see Figure 3a) may be formed on one surface of the base portion 221, which extends and protrudes in the sliding direction of the support portion 217 of the fitting means 210, in order to guide the sliding of the support portion 217 of the fitting means 210.

[0047] Furthermore, a holder 225 may be provided on the contact portion 220. Here, the holder 225 is coupled to the base portion 221 of the contact portion 220 and can surround the first and second fitting means 210a, 210b such that one side (end) of the first and second fitting means 210a, 210b is exposed. For example, the holder 225 may be formed in a "U" shape so as to surround the first and second fitting means 210a, 210b, and openings 225a may be formed on both sides so that one side (end) of the first and second fitting means 210a, 210b is exposed. Also, a fastening hole 225b may be provided on one side (rear side) of the holder 225, and the pinion gear 310 of the adjustment means 300 may be rotatably coupled to such a fastening hole 225b.

[0048] The holder 225 described above can be used in the method for manufacturing a helmet fitting system according to the present invention. Specifically, the method for manufacturing a helmet fitting system according to the present invention is as follows: First, as shown in Figure 8, the holder 225 is joined to the base portion 221. Next, as shown in Figure 9, the first and second fitting means 210a and 210b are inserted and positioned inside the holder 225 through the openings 225a formed on both sides of the holder 225. Next, as shown in Figure 10, the adjustment means 300 is joined to the fastening hole 225b of the holder 225, and the pinion gear 310 of the adjustment means 300 is gear-coupled with the rack gear 219 of the first and second fitting means 210a and 210b. At this time, one side (end) of the first and second fitting means 210a and 210b is exposed from the holder 225, so the person assembling can confirm the position of the first and second fitting means 210a and 210b, and when the first and second fitting means 210a and 210b are in the correct position, the pinion gear 310 of the adjustment means 300 can be coupled to the rack gear 219 of the first and second fitting means 210a and 210b.

[0049] Additionally, as shown in Figures 1 and 2, the band 100 may further include a third band 110. Here, the third band 110 is connected to a fitting portion 200, extends to the rearward inward side of the helmet 10, and can be coupled to the inside of the helmet 10. As such the third band 110 moves, the fitting portion 200 may move forward or backward relative to the helmet 10. At this time, the third band 110 may be coupled to a fastening portion 130 (see enlarged view in Figure 2) formed on the inside of the helmet 10. Specifically, protrusions 120 are continuously formed on both sides of the third band 110, and the third band 110 can be fixed in a specific position by coupling such protrusions 120 with the fastening portion 130 provided on the helmet 10.

[0050] In conventional helmet fitting systems, the uneven portion is formed on the underside of the band (corresponding to the third band). Therefore, when the curvature of the band changes in accordance with the shape of the helmet, the distance between the recesses and protrusions of the uneven portion changes according to the change in curvature, which causes a problem in that the wearer's feel of operation changes. Furthermore, in the helmet fitting system according to this embodiment, since an elastic force acts on the fitting portion 200, there is a risk that the change in curvature of the third band 110 will become even more severe. However, in the helmet fitting system according to this embodiment, since the uneven portion 120 is formed on both sides of the third band 110, the distance between the recesses and protrusions of the uneven portion 120 hardly changes according to the change in curvature of the third band 110, and as a result, the wearer's feel of operation can be maintained at a constant level.

[0051] As described above, the fitting portion 200 is connected to the first and second bands 100a and 100b via the elastic means 215, so that an elastic force can be provided towards the back of the wearer's head. Therefore, each time the wearer puts on or takes off the helmet 10, the elastic means 215 of the first and second fitting means 210a and 210b are stretched, and the fitting portion 200 can move backward. Thus, the wearer can easily put on or take off the helmet 10 without any additional operation. Furthermore, when the wearer puts on the helmet 10, the fitting portion 200 is provided with an elastic force towards the back of the wearer's head, so that the contact portion 220 of the fitting portion 200 contacts the back of the wearer's head, not only preventing the helmet 10 from coming off arbitrarily, but also providing the wearer with a comfortable fit.

[0052] Furthermore, by using the adjustment means 300 to move the fitting means 210 (support portion 217) away from a predetermined point X on the helmet 10 (the point where the band 100 is fixed) (see Figures 4a to 4b), the elastic force of the fitting means 210 (elastic means 215) increases, and the pressure exerted by the fitting portion 200 (contact portion 220) on the back of the wearer's head can be increased. Conversely, by using the adjustment means 300 to move the fitting means 210 (support portion 217) closer to a predetermined point X on the helmet 10 (the point where the band 100 is fixed) (see Figures 6a to 6b), the elastic force of the fitting means 210 (elastic means 215) decreases, and the pressure exerted by the fitting portion 200 (contact portion 220) on the back of the wearer's head can be reduced. Ultimately, by operating the adjustment means 300 and adjusting the elastic force of the fitting means 210 (elastic means 215), the wearer can be provided with a variety of elastic forces (compression levels) as desired.

[0053] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically illustrating the present invention, and it is clear that the present invention is not limited thereto, and that modifications and improvements can be made within the technical concept of the present invention by those with ordinary skill in the art.

[0054] Any simple modifications and changes to the present invention fall within the scope of the invention, and the specific scope of protection of the present invention will be clarified by the appended claims. [Explanation of Symbols]
