Description

TECHNICAL FIELD

[0001] The present invention relates to a helmet fitting system.

BACKGROUND ART

[0002] A helmet is used to protect a wearer's head and is classified into several types like a bicycle helmet, a ski helmet, a motorcycle helmet, and so on according to purpose thereof.

[0003] Generally, the helmet is fitted to the wearer's head by fastening chin straps provided on both sides thereof, and so as to prevent the helmet from moving after worn on the wearer's head, the helmet has a band fitted to the back part of his or her head, thereby enhancing the fitting to his or her head.

[0004] A conventional helmet is configured to have a dial for controlling the band in length. If the dial rotates in one direction, accordingly, the band becomes tight, and if the dial rotates in the other direction, the band becomes loose. Whenever the conventional helmet is put on or taken off, accordingly, the dial has to rotate to allow the band to be tightened or loosened, which causes many inconveniences in use.

[0030] Objects, characteristics and advantages of the present invention will be more clearly understood from the detailed description as will be described below and the attached drawings wherein the corresponding parts in the embodiments of the present invention are indicated by corresponding reference numerals and the repeated explanation on the corresponding parts will be avoided Terms, such as the first, the second, etc., may be used to describe various elements, but the elements should not be restricted by the terms. The terms are used to only distinguish one element from the other element. If it is determined that the detailed explanation on the well known technology related to the present invention makes the scope of the present invention not clear, the explanation will be avoided for the brevity of the description.

[0031] Now, embodiments of the present invention will be in detail described with reference to attached drawings.

[0032] FIGS. 1 and 3 are perspective views showing a helmet fitting system according to an embodiment of the present invention, FIGS.2 and 4 are enlarged perspective views showing a fitting part of the helmet fitting system according to the present invention, and FIG.5 is an exploded perspective view showing the helmet fitting system according to the present invention.

[0033] As shown in FIGS.1 to 5, a helmet fitting system according to the present invention includes a band 100 which is fixed at one end thereof to a helmet 400; and a fitting part 200 which is connected to the band 100 so as to provide an elastic force toward the back part of a wearer's head.

[0034] The band 100 serves to support the fitting part 200 thereagainst and has one end fixed to the helmet 400 and the other end connected to the fitting part 200 through elastic means 300. The band 100 is provided with one pair of bands fixed to both sides of the helmet 400 in such a manner as to be extended toward the back part of the wearer's head and thus connected to the fitting part 200. In specific, the band 100 includes a first band 110 whose one end is fixed to one side of the helmet 400 and a second band 120 whose one end is fixed to the other side of the helmet 400. For example, one end of the first band 110 is fixed to the inside of the helmet 400 facing the left side of the wearer's head, and one end of the second band 120 is fixed to the inside of the helmet 400 facing the right side of the wearer's head. In this case, one end of the first band 110 and one end of the second band 120 are fixed at positions facing each other. In addition, one end of the first band 110 and one end of the second band 120 are not fixed only to given positions of the helmet 400, but fixed to two or more positions of the helmet 400, which have different distances from the fitting part 200. That is, the two or more positions having different distances from the fitting part 200 are provided at the inside of the helmet 400, and among the two or more positions, the first band 110 and the second band 120 are each coupled to one position. For example, if the first band 110 and the second band 120 are coupled to the position having a relatively long distance from the fitting part 200, the fitting part 200 is placed at a relatively front side by means of the first band 110 and the second band 120. Contrarily, if the first band 110 and the second band 120 are coupled to the position having a relatively short distance from the fitting part 200, the fitting part 200 is placed at a relatively rear side by means of the first band 110 and the second band 120. Like this, if the position of the fitting part 200 moves according to the coupling positions of the first band 110 and the second band 120 to the helmet 400, an elastic force of the fitting part 200 that is applied to the back part of the wearer's head may be varied, and an explanation of the change in the elastic force will be described later. Further, the method for coupling the first band 110 and the second band 120 to the helmet 400 is not specifically limited, but as shown in FIG.6, the first band 110 and the second band 120 have a first protruding portion 113 and a second protruding portion 123 protruding from one end thereof, while the helmet 400 having two or more first concave portions 410 concavely formed to insert the first protruding portion 113 thereinto and two or more second concave portions 420 concavely formed to insert the second protruding portion 123 thereinto. In this case, for example, the first and second protruding portions 113 and 123 are coupled to the first and second concave portions 410 and 420 by means of snap-fit.

[0035] As shown in FIGS.1 to 5, the other end of the first band 110 is connected to the fitting part 200 by means of first elastic means 310, and the other end of the second band 120 is connected to the fitting part 200 by means of second elastic means 320. In specific, a first through hole 115 is formed on the other end of the first band 110, and accordingly, a first hook 315 provided on one end of the first elastic means 310 is fitted to the first through hole 115. In a similar manner to the above, a second through hole 125 is formed on the other end of the second band 120, and accordingly, a third hook 325 provided on one end of the second elastic means 320 is fitted to the second through hole 125. Like this, the first and second bands 110 and 120 are fixed to the helmet 400 and connected to the fitting part 200 through the elastic means 300, so that the elastic force to be applied to the back part of the wearer's head may be provided to the fitting part 200, which will be in specific described below.

[0036] The fitting part 200 serves to provide excellent fitting to the helmet 400 for the wearer, and to do this, the fitting part 200 is connected to the band 100 to provide the elastic force toward the back part of the wearer's head. Basically, the fitting part 200 is connected to the first and second bands 110 and 120 fixed to both sides of the helmet 400 and supportedly connected to a support part 500 fixed to the rear side of the helmet 400. In this case, the fitting part 200 is connected to the first and second bands 110 and 120 through the elastic means 300, and accordingly, the elastic force applied toward the back part of the wearer's head is provided to the fitting part 200. In a state where the fitting part 200 is supported against the support part 500, the fitting part 200 may be movable in forward and backward directions with respect to the helmet 400. On the other hand, only if the elastic means 300 provides the elastic force to the fitting part 200, the elastic means 300 may be not limited particularly in type, and for example, the elastic means 300 is a tension spring. However, of course, the elastic means 300 may be provided in various forms, such as, a band, rubber, silicone, and the like.

[0037] In specific, the elastic means 300 includes the first elastic means 310 adapted to connect the other end of the first band 110 to the fitting part 200 and the second elastic means 320 adapted to connect the other end of the second band 120 to the fitting part 200. In this case, one end of the first elastic means 310 is connected to the other end of the first band 110, and the other end is connected to the fitting part 200. In a similar manner as above, one end of the second elastic means 320 is connected to the other end of the second band 120, and the other end is connected to the fitting part 200. In more specific, the first hook 315 is provided on one end of the first elastic means 310 in such a manner as to be inserted into the first through hole 115 formed on the other end of the first band 110, and a second hook 317 is provided on the other end of the first elastic means 310 in such a manner as to insert a first protrusion 215a of the fitting part 200. In a similar manner as above, the third hook 325 is provided on one end of the second elastic means 320 in such a manner as to be inserted into the second through hole 125 formed on the other end of the second band 120, and a fourth hook 327 is provided on the other end of the second elastic means 320 in such a manner as to insert a second protrusion 215b of the fitting part 200. As mentioned above, the first elastic means 310 connects the first band 110 to the fitting part 200, and the second elastic means 320 connects the second band 120 to the fitting part 200. If an external force is applied to the fitting part 200 in a backward direction, the first and second elastic means 310 and 320 are expanded to allow the fitting part 200 to be moved to the rear from the front (See the change to FIG.4 from FIG.2). If the external force is removed out of the fitting part 200, the first and second elastic means 310 and 320 are contracted to allow the fitting part 200 to be moved to the front from the rear (See the change to FIG.2 from FIG.4).

[0038] Now, the fitting part 200 is specifically described, and the fitting part 200 includes a base 210 and a cover 220. In this case, the base 210 has a shape of a plate in such a manner as to be connected to the support part 500, and the cover 220 is coupled to the base 210 in such a manner as to form a given space in conjunction with the base 210. In the space formed by the base 210 and the cover 220 are located the first elastic means 310 and the second elastic means 320. In this case, the base 210 has protrusions 215 protruding therefrom, and accordingly, the second hook 317 provided on the other end of the first elastic means 310 and the fourth hook 327 provided on the other end of the second elastic means 320 are connected to the protrusions 215 of the base 210. In specific, as shown in FIG.2, if the area (left) of the fitting part 200 which is close to one side of the helmet 400 is defined as a first area A and the area (right) of the fitting part 200 which is close to the other side of the helmet 400 is defined as a second area B, the protrusions 215 include a first protrusion 215a formed on the second area B and a second protrusion 215b formed on the first area A. In this case, the second hook 317 provided on the other end of the first elastic means 310 is insertedly connected to the first protrusion 215a, and the fourth hook 327 provided on the other end of the second elastic means 320 is insertedly connected to the second protrusion 215b. Accordingly, the first elastic means 310 and the second elastic means 320 are arranged side by side in a longitudinal direction of the base 210, while overlapping each other in vertical directions (upward and downward directions) with respect to directions (longitudinal directions) where they are elastically deformed. Like this, if the first elastic means 310 and the second elastic means 320 overlap each other in the upward and downward directions, they can be stored within a relatively low thickness. Further, they are located in a relatively large area with respect to an imaginary surface contacting with the back part of the wearer's head, thereby applying uniform pressures to the back part of the wearer's head.

[0039] Moreover, the fitting part 200 includes a separation wall 225 protruding from the cover 220 so as to separate the first elastic means 310 and the second elastic means 320 from each other. That is, the first elastic means 310 and the second elastic means 320 can be isolated from each other by means of the separation wall 225. As the first elastic means 310 and the second elastic means 320 are separated from each other through the separation wall 225, they can be completely prevented from interfering with each other, while being elastically deformed.

[0040] As mentioned above, the protrusions 215 protrude from the base 210, and the separation wall 225 protrudes from the cover 220. However, of course, the protrusions 215 may protrude from the cover 220, and the separation wall 225 may protrude from the base 210, without being limited thereto. That is, the protrusions 215 and the separation wall 225 may be formed freely on the base 210 and the cover 220.

[0041] Further, as shown in FIG.5, the fitting part 200 includes guide members 217 provided on both longitudinal ends of the base 210, and the guide members 217 each include a guide hole 219. Accordingly, the first and second bands 110 and 120 pass through the guide holes 219 of the guide members 217, so that the first and second bands 110 and 120 can be freely moved with respect to the base 210. Further, the fitting part 200 includes fastening protrusions 227 formed on both longitudinal ends of the cover 220 in such a manner as to be inserted into the guide holes 219 of the guide members 217, so that the cover 220 can be coupled to the base 210.

[0042] On the other hand, the support part 500 is extended upward from the base 210 of the fitting part 200 and separately fixed to the inside of the rear side of the helmet 400. As the fitting part 200 is supported against the support part 500, it can be moved in the forward and backward directions according to the elastic deformation of the first and second elastic means 310 and 320, while being not sagged down.

[0043] In addition, a pad 600 is disposed on the fitting part 200 to provide stability in wearing for the wearer. In specific, a curvedly extended pad support 650 is disposed on one surface of the fitting part 200 which faces the back part of the wearer's head, and the pad 600 is separately coupled to the pad support 650 by means of a Velcro tape. When the helmet 400 is put on, accordingly, the pad 600 can stably come into contact with the back part of the wearer's head by means of the elastic force applied to the fitting part 200.

[0044] As mentioned above, the fitting part 200 is connected to the first and second bands 110 and 120 fixed to the helmet 400 by means of the first and second elastic means 310 and 320, and accordingly, the elastic force is applied to the back part of the wearer's head. Whenever the helmet 400 is put on and taken off, accordingly, the first and second elastic means 310 and 320 are expanded to allow ends of the first and second bands 110 and 120 to be exposed to the outside from the inside of the fitting part 200 (See the change to FIG.4 from FIG.2), and as a result, the fitting part 200 moves to the rear (See the change to FIG.8 from FIG.7). Accordingly, the helmet 400 can be easily put on and taken off, without any additional control. In this case, the fitting part 200 is supported against the support part 500, and accordingly, it can be moved in the forward and backward directions with respect to the helmet 400. When the helmet 400 is put on, further, the elastic force toward the back part of the wearer's head is applied to the fitting part 200, so that the fitting part 200 comes into contact with the back part of the wearer's head to prevent the helmet 400 from being arbitrarily taken off and to make the wearer feel comfortable.

[0045] Referring to FIG.6, on the other hand, if the coupling positions of the first and second bands 110 and 120 to the helmet 400 are changed to cause the fitting part 200 to be varied in position, the elastic force toward the back part of the wearer's head, which is applied to the fitting part 200, may be varied. For example, if the first protruding portion 113 of the first band 110 and the second protruding portion 123 of the second band 120 are coupled to the first and second concave portions 410 and 420 formed at relatively long positions from the fitting part 200, the fitting part 200 is located at a relatively front side. If the helmet 400 is put on, accordingly, relatively strong fitting is applied to the back part of the wearer's head. Contrarily, if the first protruding portion 113 of the first band 110 and the second protruding portion 123 of the second band 120 are coupled to the first and second concave portions 410 and 420 formed at relatively short positions from the fitting part 200, the fitting part 200 is located at a relatively rear side. If the helmet 400 is put on, accordingly, relatively weak fitting is applied to the back part of the wearer's head. As a result, two or more first and second concave portions 410 and 420 coupled to the first and second protruding portions 113 and 123 are formed to enable the initial setting positions to be controlled by the wearer, so that the fitting part 200 can be moved to a degree desired by the wearer to provide various elastic forces toward the back part of the wearer's head. That is, the fitting part 200 can provide various wearing fit for the wearer and can be freely moved to correspond to the wearer's head size.

Mode for Invention

[0046] FIG.9 is a sectional view showing the fitting part of a helmet fitting system according to another embodiment of the present invention. In one embodiment of the present invention as mentioned above, the first elastic means 310 and the second elastic means 320 overlap each other in the upward and downward directions (See FIG.2), but of course, they may not overlap necessarily in the upward and downward directions. For example, as shown in FIG.9, the first elastic means 310 and the second elastic means 320 may overlap each other in forward and backward directions. Like this, if the first elastic means 310 and the second elastic means 320 overlap each other in the forward and backward directions, they can be stored in a relatively small area. Accordingly, the entire area of the fitting part 200 can be minimized, thereby achieving miniaturization and providing the helmet fitting system adequate for children. In this case, the first elastic means 310 and the second elastic means 320 are located in the space formed by the base 210 and the cover 220 of the fitting part 200, and they are isolatedly located in the front and rear sides of the space by means of the separation wall 225 formed on the cover 220 of the fitting part 200.

[0047] FIG. 10 is a sectional view showing a helmet fitting system according to yet another embodiment of the present invention. In the embodiments of the present invention as mentioned above, the first elastic means 310 and the second elastic means 320 overlap each other in the upward and downward directions or in the forward and backward directions (See FIGS.2 and 9), but of course, they may not overlap necessarily. For example, as shown in FIG. 10, the first elastic means 310 and the second elastic means 320 may be located continuously with respect to each other. That is, the first elastic means 310 is extended in one direction with respect to a given position X of the fitting part 200, and the second elastic means 320 is extended in the other direction (in the opposite direction to one direction) with respect to the given position X of the fitting part 200.

[0048] In the embodiments of the present invention as mentioned above, on the other hand, the elastic means 300 includes the first elastic means 310 and the second elastic means 320, but without being limited thereto, only one elastic means may be provided so that through one elastic means 300, the first and second bands 110 and 120 can be connected to the fitting part 200.

[0049] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.

[0050] Accordingly, persons skilled in the relevant art can appreciate that many modifications and variations are possible in light of the above teachings. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
