Description

Neck cover and helmet

Technical Field

The present invention relates to a neck brace for a helmet and a helmet.

Background

Helmets are worn to protect the head in the event of an accident. In order to exert the protective performance of the helmet, after the helmet is worn with the head inserted through the opening of the helmet, the chin strap must be firmly connected to the lower side of the chin, and the helmet must be fixed to the head.

In addition, in the case of a helmet for a motorcycle, the helmet also has a function of blocking various harsh noises generated during the motorcycle running, such as engine sound, exhaust sound, wind noise, and the like, to a certain extent. Among these noises, the engine sound and the exhaust sound contain higher frequency components and are therefore significantly reduced when passing through the helmet. In contrast, wind noise contains low frequency components. Therefore, it is difficult to lower even through the helmet, which is a great annoyance to the occupant.

The wind noise includes a sound generated by friction between the body of the motorcycle and the body of the passenger and the air, and a sound of wind entering from an opening for wearing at the lower end of the helmet. Therefore, in order to improve the quietness of the interior of the helmet, it is necessary to improve the airtightness of the helmet so as to block the intrusion of sound and wind. Therefore, a method of preventing sound and wind from entering through a gap between the opening of the helmet and the neck of the wearer has been studied. Jp 61-179314 a discloses a windshield that surrounds the entire periphery of the lower end of a helmet. Although a cold-proof measure is also taken into consideration, the helmet is heavy in weight and places a large burden on the neck of the wearer because the windshield has an excessively large area.

In addition, the following method is disclosed in the specification of U.S. Pat. No. 5095550: a sheet made of a material having elasticity is fitted around the entire circumference of the lower end of the helmet and covers around the neck and under the chin of the wearer. When putting on or taking off the helmet, the barrier at the chin part is released to enlarge the opening. Such a helmet is not easy to put on and take off, and the wearer feels inconvenience that it is difficult for the wearer to move the neck.

Further, japanese patent No. 45455746 discloses a neck brace that covers the periphery of the neck of the wearer in a U-shape at the lower end of the helmet. Such a neck brace is susceptible to creating a gap between the circumference of the neck and the collar when the wearer moves around the neck.

Disclosure of Invention

Problems to be solved by the invention

In view of the above circumstances, an object of the present invention is to provide a neck brace and a helmet, which can improve the quietness of the interior of the helmet by improving the sealing property of the opening of the helmet and which do not cause inconvenience to the wearer.

Means for solving the problems

A neck brace according to a first aspect is attached to an opening into which a head of a wearer is inserted in a helmet, and extends from a peripheral edge of the opening toward the wearer, wherein an inner peripheral edge portion on the wearer side extends so as to cover at least a range from a neck portion, which is a rear portion of a neck of the wearer, to a throat portion, which is a front portion of the neck, and a pair of left and right insertion holes through which a chin strap attached to an inner side of the helmet is inserted are formed in a portion covering the throat portion.

According to the necklet of the first aspect, after the wearer puts the head into the opening and wears the helmet, if the wearer fastens the chin strap passing through the insertion hole of the necklet to the lower side of the chin, the chin strap can pull the entire helmet toward the chin, and therefore the necklet is brought into close contact with the back portion of the neck of the wearer, that is, the neck.

Further, since the insertion holes existing on the left and right sides of the neck cover are pulled downward of the chin by the chin straps, the inner peripheral portions of the left and right side portions of the neck cover are pulled toward the left and right side surfaces around the neck of the wearer. The front portion of the collar containing the insertion hole is then brought to lie against the wearer's throat by tightening the rear chinstrap.

In this way, the circumference of the wearer's neck is completely covered by the inner peripheral portion of the neck wrap. In addition, the neck cover is only fixed by the jaw belt, so that the neck of the wearer is not prevented from moving. Further, when the helmet is taken off, the front portion of the throat portion is separated from the neck of the wearer and the inner peripheral edge portion of the neck brace is also separated from the neck of the wearer when the fastening of the chinstrap is released.

A neck brace according to a second aspect is the neck brace according to the first aspect, including a portion covering a wearer's neck, a portion covering a wearer's neck from a left side to a throat, and a portion covering a wearer's neck from a right side to a throat.

According to the neckband of the second aspect, when the chin strap is tightened, the entire helmet is pulled in the direction of the chin, and therefore, the portion covering the rear portion (neck) of the neck of the wearer is easily brought into close contact with the rear portion (neck) of the neck of the wearer.

In addition, the other portions of the neck cover, i.e., the portions covering the region from the left and right sides of the neck of the wearer to the throat, are also in close contact with the periphery of the neck of the wearer as described above.

A neck brace according to a third aspect of the present invention is the neck brace according to the first or second aspect, wherein the inner peripheral edge portion is more flexible than a portion on a side farther from the wearer than the inner peripheral edge portion.

According to the neck brace of the third aspect, the inner peripheral edge portion is more flexible than the other portions. This makes it possible to more effectively transmit the tension generated when the chinstrap is fastened to the inner peripheral edge portion.

The helmet has: a cushioning material installed at an inner side of the helmet to be in contact with a wearer; and the neck cover according to any one of the first to third aspects, integrated with the cushioning material.

According to this helmet, the neck brace and the cushion material of the helmet are formed integrally, so that the number of components to be used can be reduced, and the number of assembly steps can also be reduced. Moreover, the weight of the helmet can be reduced.

Effects of the invention

As described above, the neck brace and helmet for a helmet of the present invention have excellent effects as follows: the gap between the opening of the helmet and the periphery of the neck of the wearer can be eliminated, and the sealing performance of the helmet can be improved.

Detailed Description

A helmet according to an embodiment of the present invention will be described with reference to fig. 1 to 5. The front side in the front-rear direction viewed from the wearer in a state of using the helmet is indicated by arrow FR, the right and left sides are indicated by arrows RH and LH, respectively, and the upper side in the UP-down direction is indicated by arrow UP. In the following description, the directions of the front-back, the left-right, and the up-down are only shown, and the directions of the front-back, the left-right, and the up-down are shown as viewed from a wearer wearing the helmet.

As shown in fig. 1, in the helmet 10 of the present embodiment, an opening Q through which a head enters for wearing is located at the lower end of the helmet, an opening window 42 that provides a wearer with a visual field is located on the front surface of the helmet, and a shield 18 for opening and closing the opening window 42 is rotatably attached.

The helmet 10 is covered on the outside by a shell 12 of a hard material, and on the inside is fixed a pad 14 for absorbing impact. Various cushioning materials for improving the covering feeling of the helmet are attached to the inner side of the pad 14.

In fig. 1, looking into the interior of the helmet from the open window 42, cheek pads 60 are shown as one of the cushioning materials, lying against the wearer's cheeks.

Fig. 2A shows a helmet 10 of a first embodiment. Fig. 2A shows the position of the neck collar 40 in the opening Q.

The neck cover 40 extends inward from the peripheral edge of the opening Q of the helmet 10, is U-shaped, and can cover the entire circumference of the neck from the rear portion (neck) to the front portion (throat) of the neck of the wearer. The neck brace 40 is covered on the front side (toward the outside of the helmet 10) with a strong and stretchable material such as synthetic leather, covered on the back side (toward the inside of the helmet 10) with a soft material such as suede cloth, and has a core material such as foamed synthetic resin disposed in the middle, so that it is closely attached around the neck of the wearer without hindering the putting on and taking off of the helmet 10 and the movement of the neck.

In addition, fig. 2B shows a helmet of a second embodiment.

Here, the neck cover 40 having a U-shape is divided into a neck pad 54D at the center and other portions.

The neck collar 40 is formed in a U-shape from at least three members by dividing the portion other than the neck pad 54D into two parts, i.e., a left pad and a right pad.

However, the left and right pad portions (left pad and right pad) may be further divided.

In fig. 2B, the left and right pad portions are further divided into two parts, i.e., the sub neck pad 64 and the sub collar 84, with the insertion hole 86 as a boundary.

The sub neck pad 64 is disposed at the periphery of the opening Q, extends inward of the opening, and is connected to the sub sleeve 84 by sewing, bonding, or the like.

Also, in fig. 2A and 2B, the necklet 40 or the secondary neckpad 64 is sandwiched between the shell 12 and the liner 14, thereby being mounted on the helmet 10.

However, the neck collar 40 or the secondary neck pad 64 may be snap-fitted to the inside of the pad 14 like a cushion material such as the cheek pad 60 (see fig. 1). Alternatively, the cushion material may be disposed inside the cushion material and directly fixed by hook and loop fastening or by snap fastening.

In short, the mounting position and the mounting method are not limited as long as the neck collar 40 can be configured to cover the circumference of the neck of the wearer.

However, it is preferable that the neck cover 40 or the sub-neck pad 64 be detachably mounted for washing or replacement of consumables.

Fig. 3 is a perspective view showing a state in which the helmet 10 according to the embodiment of the present invention is worn on the wearer P and the chin strap 20 is fastened, as viewed from the right side of the wearer obliquely from below.

Since the entire helmet is pulled toward the chin by tightening the chin strap 20, the rear portion of the neckband 40 (see fig. 2A) or the neckpad 54D (see fig. 2B) is brought into close contact with the rear portion of the neck of the wearer.

Further, since the left and right insertion holes 86 existing in the front portion of the neck brace 40 or the sub-neck pad 64 are pulled toward the chin by the chinstrap 20, the inner peripheral edge portions of the left and right side portions of the neck brace 40 or the inner peripheral edge portions of the left and right sub-braces 84 are pulled toward the left and right side surfaces of the wearer's neck circumference P1, respectively. Further, the front portion of the neck brace 40 including the insertion hole 86 or the front end portion 84A (see fig. 4) of the sub-brace is closely attached to the throat of the wearer by the fastened chinstrap, and thus the wearer's neck circumference P1 is completely sealed. (refer to FIG. 3)

Fig. 4 shows a right side pad 70R of the second embodiment.

The right pad 70R is divided into two parts, a secondary neck pad 64 and a secondary sheath 84. Since the sub-sleeve 84 includes an inner peripheral portion for abutting against the wearer's neck circumference P1, it is preferably made of a softer and more stretchable material than the sub-neck pad 64.

As described above, the neck cover 40 is made of a strong and durable material such as synthetic leather on the front surface side, a core material such as foamed synthetic resin is disposed in the middle, and the back surface side is covered with a suede fabric or the like.

The sub-sleeve 84 can be made of a flexible material on the front surface side, or can be made of a thin material even if it is made of the same material as the neck sleeve, and can be made of a material having elasticity by replacing the fabric on the back surface side with a material having elasticity, thereby improving the close contact with the wearer's neck region P1.

Further, by providing the insertion hole 86 in the sub-sleeve 84, the tension force when the chin strap 20 is fastened can be transmitted to the inner peripheral edge portion more efficiently and effectively.

The right pad 70R is attached to the peripheral edge portion on the opposite side of the sub-cover 84 by sewing or the like with a locking plate 82, and a locking groove 82A of the locking plate 82 is locked to a not-shown boss portion fixed between the case 12 and the pad 14 (see fig. 2A and 2B).

However, as described above, the mounting position and the mounting method are not limited.

Fig. 5 shows the center pad, cheek pads and helmet body removed from a helmet of a second example of an embodiment of the invention.

Cheek pads 60 are cushioning material disposed along the cheeks of the wearer.

In fig. 5, cheek pad 60R (right side) is integrated with right side pad 70R by sewing, bonding, snap-fastening, or the like. As described above, the right pad 70R is locked to the helmet 10, and the cheek pads 60 are locked to the catches 36 located inside the helmet (the side surfaces of the pad 14).

In this way, the right pad 70R is detachably attached to the helmet.

Although not shown, the left pad 70L is also attached in the same manner.

The center pad 54 has a crown pad (portions throughout 54A, 54B, and 54C of fig. 5) and a neck pad 54D respectively disposed along the wearer's head (parietal, front, and lateral heads) and the back of the neck (neck).

The center pad 54 has a front locking portion 54F at a position extending forward from the lower end of the front head arrangement portion 54B, and is locked to the front side of the pad 14. The back surface side of the neck pad 54D is provided with a catch 36 to be locked to the back side of the pad 14.

As described above, the neck brace of the second embodiment can be detachably attached to the helmet by being integrated with the cushioning material of the helmet 10.

Further, the number of components to be used can be reduced by integrating the cushioning material, and the number of assembly steps can be reduced. Moreover, the weight of the helmet can be reduced.

Further, when cheek pad 60 is connected to neck pad 54D, a U-shaped cushion member is formed at the periphery of opening Q. When the neck cover 40 is connected to the U-shaped buffer, the state shown in fig. 2A is obtained.

That is, the neck brace of the first embodiment may be integrated with the cushioning material of the helmet.

(action and Effect of the present embodiment)

Next, the operation and effect of the present embodiment will be described.

As shown in fig. 2A, 2B and 3, in the neck brace 40 of the present embodiment, after the helmet 10 is worn with the head inserted into the opening Q, when the chin strap 20 passed through the insertion hole 86 of the neck brace 40 is tightened to the lower side of the chin, the entire helmet 10 is pulled toward the chin by the chin strap 20, and therefore the neck brace 40 is brought into close contact with the rear portion of the neck of the wearer P. Further, since the insertion holes 86 existing on the left and right sides of the neck brace 40 are pulled downward of the chin by the chin strap 20, the inner peripheral edge portions of the left and right side portions of the neck brace 40 are pulled up to the left and right side surfaces around the neck of the wearer. Then, the front portion of the neck brace 40 including the insertion hole 86 is closely attached to the throat of the wearer P by the fastened chinstrap 20.

In this way, the neck circumference P1 of the wearer P is completely covered by the inner peripheral portion of the neck cover 40. In addition, since the neck cover 40 is fixed only by the chinstrap, the wearer P is not hindered from moving the neck. When the helmet 10 is taken off, the fastening of the chin strap 20 is released, and the front portion of the throat portion is separated from the neck of the wearer, and the inner peripheral edge portion of the neckband 40 is also separated from the neck of the wearer P.

In the description of the present embodiment, a helmet for riding on a motorcycle is mainly described as an example, but as described above, the neckband of the present embodiment can be used as long as it is a helmet that includes an opening into which a head enters to wear the helmet and a chinstrap for holding the helmet.

That is, the helmet can be used for a bicycle, a sport helmet, a snow-run helmet, a water ski helmet, and the like.

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and it goes without saying that various modifications other than the above can be made without departing from the scope of the present invention.
