Description

Helmet fit system

Technical Field

The present invention relates to a helmet fit system.

Background

Helmets are used to protect the head of a wearer, and are classified into various types such as bicycle helmets, ski helmets, motorcycle helmets, and the like according to the use thereof.

Generally, a helmet is mounted on a wearer's head by fastening chin straps provided at both sides thereof to prevent the helmet from moving after being worn on the wearer's head, and the helmet is mounted with straps at the rear of his or her head to enhance the fit to his or her head.

Conventional helmets are configured with dials for controlling the length of the strap. If the dial is rotated in one direction, the belt will tighten accordingly, and if the dial is rotated in the other direction, the belt will loosen. Accordingly, the conventional helmet, whether put on or taken off, requires the dial to be rotated to allow the tightening or loosening of the strap, which causes a lot of inconvenience to use.

Various elements may be described using terms such as first, second, etc., but these elements should not be limited by terms. These terms are only used to distinguish one element from another element. If it is determined that detailed description of known technologies related to the present invention would obscure the scope of the present invention, explanation will be omitted for simplicity of description.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Fig. 1 and 3 are perspective views showing a helmet fit system according to an embodiment of the present invention, fig. 2 and 4 are enlarged perspective views showing fit components of the helmet fit system according to the present invention, and fig. 5 is an exploded perspective view showing the helmet fit system according to the present invention.

As shown in fig. 1 to 5, the helmet fit system according to the present invention includes: a strap 100 secured at one end thereof to a helmet 400; and a fitting part 200 connected to the band 100 to provide an elastic force to the rear of the wearer's head.

The strap 100 serves to support the fitting part 200, and one end thereof is fixed to the helmet 400 and the other end thereof is connected to the fitting part 200 through the elastic means 300. The strap 100 is provided with a pair of straps fixed to both sides of the helmet 400 such that the pair of straps extend toward the rear of the wearer's head and thus are connected to the fitting part 200. Specifically, the strap 100 includes a first strap 110 having one end fixed to one side of the helmet 400, and a second strap 120 having one end fixed to the other side of the helmet 400. For example, one end of the first strap 110 is fixed to the inside of the left side of the helmet 400 facing the wearer's head, and one end of the second strap 120 is fixed to the inside of the right side of the helmet 400 facing the wearer's head. In this case, one end of the first belt 110 and one end of the second belt 120 are fixed to positions facing each other. In addition, one end of the first strap 110 and one end of the second strap 120 are not only fixed to a given position of the helmet 400, but are fixed to two or more positions of the helmet 400, which are different in distance from the fitting part 200. That is, two or more positions having different distances from the fitting part 200 are provided at the inner side of the helmet 400, and in the two or more positions, the first strap 110 and the second strap 120 are coupled to one position, respectively. For example, if the first and second straps 110 and 120 are coupled to positions having a relatively long distance from the mating fitting 200, the mating fitting 200 is placed at opposite front sides by means of the first and second straps 110 and 120. Conversely, if the first and second straps 110, 120 are coupled to a position having a relatively short distance from the mating member 200, the mating member 200 is placed on the opposite rear side by means of the first and second straps 110, 120. As such, if the position of the fitting part 200 is moved according to the coupling position of the first and second straps 110 and 120 to the helmet 400, the elastic force of the fitting part 200 applied to the rear of the wearer's head can be changed, and an explanation of the change in the elastic force will be described later. Further, the method for coupling the first and second straps 110 and 120 to the helmet 400 is not particularly limited, but as shown in fig. 6, the first and second straps 110 and 120 have the first and second protrusions 113 and 123 protruding from one end thereof, and the helmet 400 has two or more first recesses 410 concavely formed to insert the first protrusions 113 therein and has two or more second recesses 420 concavely formed to insert the second protrusions 123 therein. In this case, for example, the first and second protrusions 113, 123 are coupled to the first and second recesses 410, 420 by means of snap-fitting.

As shown in fig. 1 to 5, the other end of the first strap 110 is connected to the mating member 200 by means of a first elastic means 310, and the other end of the second strap 120 is connected to the mating member 200 by means of a second elastic means 320. Specifically, a first through hole 115 is formed on the other end of the first strap 110, and accordingly, a first hook 315 provided at one end of the first elastic means 310 is mounted 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 belt 120, and accordingly, a third hook 325 provided at one end of the second elastic means 320 is mounted to the second through hole 125. In this way, the first and second straps 110, 120 are fixed to the helmet 400 and connected to the fitting part 200 through the elastic means 300 so that an elastic force applied to the rear of the wearer's head can be provided to the fitting part 200, which will be described in detail below.

The fitting part 200 serves to provide a good fit for the wearer with the helmet 400, for which purpose the fitting part 200 is connected to the strap 100 to provide a rear elastic force toward the wearer's head. Basically, the fitting part 200 is connected to the first and second straps 110 and 120 fixed to both sides of the helmet 400 and supportively connected to the supporting 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 by the elastic means 300, and thus, an elastic force applied toward the rear of the wearer's head is provided to the fitting part 200. The fitting part 200 may be moved forward and backward with respect to the helmet 400 in a state where the fitting part 200 is supported on the support part 500. On the other hand, the elastic means 300 may not be particularly limited in type only when the elastic means 300 provides an elastic force to the mating member 200, 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 belt, rubber, silicone, or the like.

Specifically, the elastic means 300 includes a first elastic means 310 adapted to connect the other end of the first strap 110 to the mating member 200 and a second elastic means 320 adapted to connect the other end of the second strap 120 to the mating member 200. In this case, one end of the first elastic means 310 is connected to the other end of the first strap 110, and the other end is connected to the fitting part 200. In a similar manner to that described above, one end of the second elastic means 320 is connected to the other end of the second belt 120, and the other end is connected to the fitting part 200. More specifically, the first hook 315 is provided on one end of the first elastic means 310 so as to be inserted into the first through hole 115 formed at the other end of the first strap 110, and the second hook 317 is provided on the other end of the first elastic means 310 so as to be inserted into the first protrusion 215a of the fitting part 200. In a similar manner to the above, the third hook 325 is provided at one end of the second elastic means 320 such that it is inserted into the second through hole 125 formed at the other end of the second band 120, and the fourth hook 327 is provided at the other end of the second elastic means 320 such that it is inserted into the second protrusion 215b of the mating member 200. As described above, the first elastic means 310 connects the first strap 110 to the mating component 200, and the second elastic means 320 connects the second strap 120 to the mating component 200. If an external force is applied to the fitting part 200 in a backward direction, the first and second elastic means 310, 320 are stretched to allow the fitting part 200 to move from front to back (see the variation from fig. 2 to 4). If the external force is removed from the mating member 200, the first and second elastic means 310, 320 contract to allow the mating member 200 to move from back to front (see the variation from fig. 4 to fig. 2).

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 plate shape to be connected to the support member 500, and the cover 220 is coupled to the base 210 so as to form a given space together with the base 210. The first elastic means 310 and the second elastic means 320 are located in a space formed by the base 210 and the cover 220. In this case, the base 210 has a protrusion 215 protruding therefrom, and thus, 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 protrusion 215 of the base 210. Specifically, as shown in fig. 2, if an area (left) of one side of the fitting part 200 near the helmet 400 is defined as a first area a and an area (right) of the other side of the fitting part 200 near the helmet 400 is defined as a second area B, the protrusion 215 includes 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 the longitudinal direction of the base 210 while overlapping each other in the vertical direction (up-down direction) with respect to the direction in which they are elastically deformed (longitudinal direction). In this way, if the first elastic means 310 and the second elastic means 320 overlap each other in the up-down direction, they can be stored in a relatively low thickness. Furthermore, they are located in a relatively large area with respect to an imaginary surface in contact with the rear of the wearer's head, thereby exerting uniform pressure on the rear of the wearer's head.

Further, the fitting part 200 includes a partition wall 225 protruding from the cover 220 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 separated from each other by the partition wall 225. Since the first elastic means 310 and the second elastic means 320 are separated from each other by the partition wall 225, they can be completely prevented from interfering with each other while being elastically deformed.

As described above, the protrusion 215 protrudes from the base 210, and the partition wall 225 protrudes from the cover 220. However, of course, the protrusion 215 may protrude from the cover 220, and the partition wall 225 may protrude from the base 210, but is not limited thereto. That is, the protrusion 215 and the partition wall 225 may be freely formed on the base 210 and the cover 220.

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, 120 pass through the guide hole 219 of the guide member 217 so that the first and second bands 110, 120 can freely move with respect to the base 210. Further, the fitting part 200 includes fastening protrusions 227 formed on both longitudinal ends of the cover 220 such that the fastening protrusions 227 are inserted into the guide holes 219 of the guide member so that the cover 220 can be coupled to the base 210.

On the other hand, the support member 500 extends upward from the base 210 of the fitting member 200 and is separately fixed to the inside of the rear side of the helmet 400. Since the fitting member 200 is supported on the supporting member 500, it can move in the front-rear direction according to the elastic deformation of the first and second elastic means 310, 320 without sagging.

In addition, a cushion 600 is provided on the fitting part 200 to provide stability to the wearer when worn. Specifically, a cushion support 650 extending in a curved manner is provided on one surface of the rear portion of the fitting part 200 facing the wearer's head, and the cushion 600 is individually coupled to the cushion support 650 by a Velcro tape. Accordingly, when the helmet 400 is worn, the pad 600 can be stably brought into contact with the rear of the wearer's head by the elastic force applied to the fitting part 200.

As described above, the fitting part 200 is connected to the first and second bands 110, 120 fixed to the helmet 400 by the first and second elastic means 310, 320, and thus, elastic force is applied to the rear of the wearer's head. Each time the helmet 400 is put on and taken off, the first and second elastic means 310, 320 are stretched accordingly to allow the ends of the first and second bands 110, 120 to be exposed to the outside from the inside of the fitting part 200 (see the variation from fig. 2 to fig. 4), and as a result, the fitting part 200 moves rearward (see the variation from fig. 7 to fig. 8). 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 on the supporting part 500, and thus, it can move in the front-rear direction with respect to the helmet 400. When the helmet 400 is worn, an elastic force toward the rear of the wearer's head is further applied to the fitting part 200 so that the fitting part 200 contacts the rear of the wearer's head to prevent the helmet 400 from being arbitrarily taken off and to make the wearer feel comfortable.

Referring to fig. 6, on the other hand, if the coupling positions of the first and second straps 110, 120 with the helmet 400 are changed to cause the position of the fitting part 200 to be changed, the elastic force applied to the rear of the fitting part 200 toward the wearer's head may be changed. For example, if the first protrusion 113 of the first strap 110 and the second protrusion 123 of the second strap 120 are coupled to the first and second recesses 410, 420 formed at relatively long positions from the mating member 200, the mating member 200 is located at opposite front sides. Accordingly, if the helmet 400 is worn, a relatively strong fit may be applied to the rear of the wearer's head. In contrast, if the first protrusion 113 of the first strap 110 and the second protrusion 123 of the second strap 120 are coupled to the first and second recesses 410, 420 formed at relatively short positions from the mating member 200, the mating member 200 is located at opposite rear sides. Thus, if the helmet 400 is worn, a relatively weak fit may be applied to the rear of the wearer's head. As a result, two or more first and second recesses 410 and 420 coupled to the first and second protrusions 113 and 123 are formed to enable the wearer to control the initial set position, so that the fitting part 200 can be moved to a degree required by the wearer to provide different elastic forces toward the rear of the wearer's head. That is, the fitting part 200 can provide various wearing degrees of fitting for the wearer and can be freely moved to correspond to the head size of the wearer.

MODE OF THE INVENTION

Fig. 9 is a cross-sectional view illustrating a fitting part of a helmet fitting system according to another embodiment of the present invention. In one embodiment of the present invention as described above, the first elastic means 310 and the second elastic means 320 overlap each other in the up-down direction (see fig. 2), but of course, they may not necessarily overlap in the up-down direction. For example, as shown in fig. 9, the first elastic means 310 and the second elastic means 320 may overlap each other in the front-rear direction. As such, if the first elastic means 310 and the second elastic means 320 overlap each other in the front-rear direction, 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 a helmet fitting system suitable 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 located at the front side and the rear side of the space, respectively, by means of the partition wall 225 formed on the cover 220 of the fitting part 200.

Fig. 10 is a cross-sectional view illustrating a helmet fit system according to yet another embodiment of the present invention. In the above-described embodiment of the present invention, the first elastic means 310 and the second elastic means 320 overlap each other in the up-down direction or the front-rear direction (see fig. 2 and 9), but of course, they may not necessarily overlap. For example, as shown in fig. 10, the first elastic means 310 and the second elastic means 320 may be continuously positioned with respect to each other. That is, the first elastic means 310 extends in one direction with respect to the given position X of the mating member 200, and the second elastic means 320 extends in the other direction (in the opposite direction to the one direction) with respect to the given position X of the mating member 200.

In the embodiment of the present invention as described above, on the other hand, the elastic means 300 includes the first elastic means 310 and the second elastic means 320, but is not limited thereto, and only one elastic means may be provided so that the first and second bands 110, 120 can be connected to the fitting part 200 by one elastic means 300.

While the present invention has been described with reference to the particular illustrative embodiments, the present invention is not to be limited by such embodiments, but only by the following 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.

Thus, those skilled in the relevant art will appreciate that many modifications and variations are possible in light of the above teaching. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
