Liner structure of bulletproof helmet and manufacturing process thereof

Abstract

The invention discloses a liner structure of a bulletproof helmet and a manufacturing process thereof. The liner structure comprises a buffer layer and a comfortable layer; the buffer layer comprisesa front structure, a top structure and a rear structure, wherein the front structure adopts three elliptical structures with the same size and shape, which are unfolded backwards in a circular arc shape at equal intervals; the rear structure also adopts three elliptical structures with the same size and shape, which are unfolded forwards in a circular arc shape at equal intervals; the top structure is in an elliptical shape with a cross-shaped groove in the center; the buffer layer is connected by hook and loop fasteners to the inside of the helmet; and the comfort layer comprises seven groupsof single liner structures which are connected by hook and loop fasteners to the buffer layer. The liner structure is manufactured by adopting a special process, the structural design is simple and scientific, the impact buffering effect is excellent, the weight is light, the comfort degree of helmet fitting by a wearer is greatly improved, and the discomfort of the wearer is reduced; air flow inthe helmet is improved, and the temperature difference between the inside of the helmet and the outside world after the helmet is worn in different seasons and different environments is improved, sothat discomfort caused after the helmet is taken off is avoided, and the sweating frequency of a wearer is reduced.

Description

technical field [0001] The invention belongs to the technical field of protection, in particular to a liner structure of a bulletproof helmet and a manufacturing process thereof. Background technique [0002] The existing bulletproof helmet liner system is generally designed and manufactured with a combined structure of soft sponge and EVA. If the impact resistance of the bulletproof helmet needs to be improved, the use area and thickness of the liner system must be greatly increased. Increase, the overall weight of the pad system will increase, thereby increasing the wearer's load and reducing the fit when wearing; [0003] Moreover, when the area of ​​the pad system is too large, the air flow inside the bulletproof helmet will be reduced, further affecting the comfort of the wearer; especially the increase in the top area and thickness will bring greater pressure to the head, affecting the wearer.

Problems solved by technology

[0002] The existing bulletproof helmet liner system is generally designed and manufactured with a combined structure of soft sponge and EVA. If the impact resistance of the bulletproof helmet needs to be improved, the use area and thickness of the liner system must be greatly increased. Increase, the overall weight of the pad system will increase, thereby increasing the wearer's load and reducing the fit when wearing;

[0003] Moreover, when the area of ​​the pad system is too large, the air flow inside the bulletproof helmet will be reduced, further affecting the comfort of the wearer; especially the increase in the top area and thickness will bring greater pressure to the head, affecting the wearer. The normal performance of tactical actions, and wearing an overweight bulletproof helmet for a long time will also cause damage to the wearer's cervical spine and increase the physical exertion of individual soldiers. In actual combat, the weight of a soldier can often affect the victory or defeat of the battle;
