Wearing device for helmet of firefighter for urban rescue

Abstract

The invention relates to a wearing device for a helmet of a firefighter for urban rescue. The wearing device is composed of an ear drawstring, a lateral drawstring, a chin support, an adjusting component, a nape comfort pad, a chin strap, a helmet ring, a helmet edge comfort pad, a helmet hoop, a buffering cushion, a width-adjusting rope and a buffering belt, wherein a slot is arranged on the helmet ring; the helmet ring is connected with the helmet hoop by plugging a pin into the slot; one end of the width-adjusting rope passes through four belt holes of the buffering belt in turn; two ends of the width-adjusting rope are fastened into a knot; the two ends of the buffering belt respectively pass through four slotted holes in the helmet ring and are arrayed in a 90-degree crossing mode; the buffering belt and the buffering cushion are fixed by using a magic hasp; and a linkable adjusting system is formed by the ear drawstring and the lateral drawstring through a drawstring-dividing piece. During the process of tightening a head girth, the center of gravity of the helmet has a trend of gradually moving backward, thereby being beneficial to the balancing of the problem of the forward inclined center of gravity of a helmet system caused by a goggle and a floodlight mounted on the front part, and being beneficial to the promotion of wearing stability; a clearance between a top pad and a helmet shell can be adjusted along the vertical direction by adjusting the tightness degree of the width-adjusting rope; the height of the helmet for the firefighter can be adjusted for adapting to different head size of the firefighter; and the wearing stability and comfort are increased.

Description

Technical field [0001] The invention belongs to the technical field of firefighters' personal protective equipment, and specifically relates to a firefighter's helmet wearing device for urban rescue and rescue. Background technique [0002] City rescue helmets for firefighters are helmets used to protect their heads when firefighters conduct rescue operations in urban buildings and collapsed buildings, narrow spaces, vehicles and machinery accident sites. They are mainly used to prevent mechanical piercing and heavy damage. Damage to the head of firefighters caused by falling objects or squeezing, electric current, high temperature, flame and other dangerous factors. The internal helmet-wearing device forms an energy absorbing system at the head and cap top space, which can buffer, disperse and absorb external shocks, so that it can be distributed to a large area of ​​the head as much as possible to reduce impact acceleration The peak value is within the limit of the impact forc...
