Nested air bag safety helmet

Abstract

The invention discloses a nested air bag safety helmet which comprises a helmet housing and an inferior frontal belt (7) and is characterized in that the helmet housing adopts an air bag framework; the air bag framework is a nested air bag; the nested air bag comprises an external air bag (12) and an internal air bag (16); the internal air bag (16) is embedded into the external air bag (12); an internal wall (1) of the external air bag (12) is connected with a helmet tension band (4) via a plastic bracket (3); and the helmet tension band (4) is connected with a cross girdle (9), the inferior frontal belt (7) and a rear hoop (6). The nested air bag safety helmet solves the technical problems that a wearer is uncomfortable due to large mass of the safety helmet, the safety helmet is not designed with a brim structure and cannot protect body sites such as an after brain, ears and a face, and the number of holes in the helmet housing and hole diameters are small in order to ensure firmness of the safety helmet resulting in low air permeability in the prior art.

Description

technical field [0001] The invention belongs to the technical field of safety helmets, in particular to a nested airbag safety helmet. Background technique [0002] The design of the safety helmet needs to meet the requirements of use, the most important of which is to protect the operator's head from injury and to wear it comfortably. At present, the materials used by manufacturers at home and abroad to manufacture safety helmet shells include glass fiber reinforced polypropylene, ABS, toughened modified polypropylene, polycarbonate (PC), high-density polyethylene (HDPE), polyester fiberglass, etc. Although the helmet shell made of these materials is hard and impact-resistant; but the helmet is of high quality, and it will press the head like a stone when worn on the head, making the wearer feel very uncomfortable. On the one hand, the safety helmets on the market do not have a brim structure, which cannot protect the back of the head, ears, face and other body parts; not...

AI Technical Summary

Problems solved by technology

The nested airbag safety helmet of soft PVC resin material is used to solve the problem that the safety helmet in the prior art has a large mass and is not comfortable for the wearer to wear. The safety helmet does not have a brim structure and cannot protect the back of the head, ears, face and other body parts; another On the one hand, in order to take into account the robustness of the helmet, the number of holes in the shell is small and the hole diameter is small, resulting in technical problems such as poor air permeability
