Description

Technical Field

[0001] The invention relates to the technical field of lining textile design, in particular to a T-shaped soft pack liner for a helmet. Background Art

[0002] Flight helmets are large and heavy, and because the temperature and humidity of high-altitude flight conditions vary greatly, pilots' heads can easily feel uncomfortable. According to the requirements of the document GJB_1564A-2012 "General Specifications for Flight Protection Helmets", the lining of the helmet must be able to stably support head movement, ensure breathability and sweat absorption, and not be stuffy when worn. The padding should fit the head tightly, be comfortable to wear, and not cause head clamping. It should be moderately soft and hard. Considering the vibration during flight, it should have a shock-absorbing effect. The inner padding should include an airbag inflation mechanism at the back of the head to prevent the brain from coma due to decompression. Its materials should also have special characteristics: the product should have a certain flame retardant performance, and at the same time be resistant to high and low temperatures, mold, damp heat, and salt spray environments.

[0003] The existing flight helmet lining design often follows the design method of ordinary helmet lining, and its lining cannot provide a good sense of support for the head. Its shape design is simple, and it cannot fit the inner surface of the helmet well, nor can it fit the shape of the human head well. During the wearing process, it is also easy to fall off and dislocate. Once it falls off, it is difficult to find a suitable position inside the helmet to fix it.

[0004] Existing flight helmet linings rarely consider the special needs of linings in flight environments, and the experience is not good in terms of temperature and humidity control. Because flight helmets are not breathable, cover a large area of ​​the head, and are heavy, they will feel stuffy after long-term use, causing increased sweating and affecting the pilot's flight experience. Some existing flight helmet linings are too thin and lack the effect of shock absorption when worn. Summary of the invention

[0005] The object of the present invention is to provide a T-shaped soft pack liner for a helmet to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1-4 , the present invention provides a technical solution:

[0032] A T-shaped soft pack liner for a helmet, comprising a liner body and a helmet body 25, wherein the liner body comprises a first liner body 1 and a second liner body 2, wherein the first liner body 1 and the second liner body 2 are both T-shaped liner bodies, wherein the rear end of the first liner body 1 is located at the front end of the second liner body 2, and the middle of the rear end of the first liner body 1 and the middle of the front end of the second liner body 2 are connected to form a liner body through a plurality of Velcro portions;

[0033] The Velcro part includes a Velcro hook surface 6 and a Velcro fur surface 7, the Velcro hook surface 6 is located at the rear end of the first pad body 1 and the front end of the second pad body 2, and the Velcro fur surface 7 is located at the back of the first pad body 1 and the second pad body 2;

[0034] The shape of the pad body can fit the inner shape of the helmet body 25. Thirteen buffering action parts 3 are arranged on the surface of the first pad body 1 and the second pad body 2. The thirteen buffering action parts 3 cover twelve stress points of the head to protect the wearer's brain and reduce the sense of head shock. The buffering action part 3 at the rear end of the first pad body 1 and the buffering action part 1 at the front end of the second pad body 2 are a whole covering one stress point of the head.

[0035] Specifically, Figure 1 , 2 As shown, after the first pad body 8 and the second pad body 9 are connected by a plurality of Velcro parts, the rearmost buffering part 1 of the first pad body 8 and the frontmost buffering part 1 of the second pad body 9 will be connected, thereby covering a head stress point.

[0036] The rear end of the second pad body 2 is provided with an airbag installation pocket 4, the inside of which is provided with an airbag device, and the top of the surface of the airbag installation pocket 4 is provided with a zipper 5. When installing the airbag device, the airbag part of the airbag device is loaded into the airbag installation pocket 4, and then the airbag device is connected to the outside through a pipeline. In the emergency situation of decompression in the cabin, the airbag will automatically inflate, thereby squeezing the back of the brain, forcing the blood in the human brain to concentrate and keep awake. Such a design and installation method can solve the problem of installing and fixing the airbag device on the inside of the helmet body 25, and ensure the simplicity and integrity of the flight helmet equipment.

[0037] Furthermore, the first pad body 1 and the second pad body 2 are bonded by a plurality of Velcro parts 6, the Velcro part 6 is divided into a first Velcro hook surface part 8, a second Velcro hook surface part 9, a third Velcro hook surface part 10, a fourth Velcro hook surface part 11, a fifth Velcro hook surface part 12, a sixth Velcro hook surface part 13, and a seventh Velcro hook surface part 14, and the Velcro fur surface 7 is divided into a sixth Velcro fur surface part 15, a seventh Velcro fur surface part 16, a third Velcro fur surface part 17, a fourth Velcro fur surface part 18, a first Velcro fur surface part 19, and a second Velcro fur surface part 2 0. The fifth Velcro fleece surface portion 21, the first Velcro hook surface portion 8 is pasted to the first Velcro fleece surface portion 19, the second Velcro hook surface portion 9 is pasted to the second Velcro fleece surface portion 20, the third Velcro hook surface portion 10 is pasted to the third Velcro fleece surface portion 17 on the back thereof, the fourth Velcro hook surface portion 11 is pasted to the fourth Velcro fleece surface portion 18 on the back thereof, the fifth Velcro hook surface portion 12 is pasted to the fifth Velcro fleece surface portion 21, the sixth Velcro hook surface portion 13 is pasted to the sixth Velcro fleece surface portion 15, and the seventh Velcro hook surface portion 14 is pasted to the seventh Velcro fleece surface portion 16.

[0038] Furthermore, the combination of the first pad body 1 and the second pad body 2 is bonded to the Velcro hook surface inside the helmet body 25 through the Velcro fleece surface 7 on the back.

[0039] Furthermore, the structure of the first pad body 1 and the second pad body 2 is sewn with three layers of multifunctional composite fabrics made of different materials, the outside, the middle and the inside. The three layers of material are coolmax polyester fiber cooling material 22, Aeros-tex fiber material 23, and TPU composite fabric 24 from the inside to the outside.

[0040] Furthermore, the coolmax polyester fiber cool material 22 is a high specific heat capacity fiber material, which absorbs more heat, slows down the time of heat accumulation discomfort, and prolongs the "no sense of adaptation" period of wearing. The surface of this layer is in close contact with the hair, and needs to be treated with antistatic to reduce static adsorption. It needs to be treated with oil repellent to reduce the adhesion of oil stains on the hair.

[0041] Specifically, Aeros-tex fiber material 23 has the property of low thermal conductivity, which can ensure the warmth requirement of the wearer at high altitudes, and has a unique fiber structure, which can improve the air permeability to a certain extent. In terms of sweat and moisture removal, it has the properties of high moisture conduction and air permeability, and uses the power of rising hot and humid air flow to conduct moisture to the inner side of the outermost fabric.

[0042] Furthermore, the outer surface of the TPU composite fabric 24 is subjected to a dot-brushed treatment.

[0043] Furthermore, the interior of the buffering area 3 is filled with buffer material.

[0044] Specifically, the outermost fabric of the liner uses TPU composite fabric, which has the characteristics of waterproof and breathable, wear-resistant and washable, and is subjected to a nap treatment to increase its wear resistance. The outermost layer is a tight fabric, and a polymer water-absorbing material can be attached to the inner surface to reduce the precipitation of condensed water. The polymer water-absorbing material must be recyclable (can be dehydrated and recycled). The fabric is a high-strength, wear-resistant napped fabric that can be combined with the Velcro on the foamed buffer foam layer inside the helmet body 11. In terms of perspiration and moisture discharge, the outer surface of the outermost layer of fabric is treated with dot-shaped napping to further increase the hot and humid air flow channel to facilitate the discharge of hot and humid air; at the same time, it also reduces accidental adhesion to the Velcro.

[0045] It should be noted that assembling the pad body in the helmet body 25 is divided into three steps:

[0046] Step S1, bonding two T-shaped pads, the first pad body 1 and the second pad body 2, into a whole through a plurality of Velcro parts;

[0047] Step S2, the whole inner liner is adhered to the inner side of the helmet body 25 through the Velcro surface 7 on the back side of the liner body and fixed;

[0048] Step S3 , installing the airbag device in the airbag installation pocket 4 on the rear side of the liner, and pulling the chain 5 to fix the airbag of the airbag device to the inside of the airbag installation pocket 4 .

[0049] Working principle: When in use, firstly, the first pad body 1 and the second pad body 2 are spliced ​​together. A plurality of Velcro parts on the pad body are combined into a three-dimensional hollow shape, and then the pad body is fixed to the foam cushioning material inside the helmet body 11 through the Velcro fur surface 7 on the back of the pad body.

[0050] The outermost material of the first pad body 1 and the second pad body 2 is a high-strength wear-resistant napped fabric, which can be combined with the Velcro on the foamed buffer foam layer inside the helmet body 11. There are six Velcro positions on the foam buffer layer inside the helmet body 25, which can be bonded and fixed with the Velcro fleece surface on the back of the pad body.

[0051] Finally, the airbag device is loaded into the airbag installation pocket 4 and can be used.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
