Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The structure of the protective vest of the present invention includes a protective cover 1. The shape of the protective cover 1 matches the shape of the user's back and focuses on protecting the user's spine. Compared with the traditional protective vest, the present invention has less consumables and is light in weight. The two ends of protective cover 1 are respectively provided with a high-strength pressure tank 2, and the top of high-strength pressure tank 2 is provided with gas nozzle 8, and the top of protective cover 1 is provided with air bag 3, and air bag 3 is connected with high-strength pressure tank 2 by gas nozzle 8. The protective cover 1 is provided with a pull rod 7, and the pull rod 7 is connected with the high-strength air tank 2. A first safety belt 4 is connected between the protective cover 1 and the airbag 3 . ...

Abstract

The invention discloses a protective waistcoat comprising a protective cover. A high-strength air pressure tank is arranged at each of two ends of the protective cover. An air cock is arranged at the top of each high-strength air pressure tank. Airbags are arranged at the top of the protective cover and are connected with the high-strength air pressure tanks through the air cocks. The problem of ultrahigh weight of protective waistcoats in the prior art is solved. By the protective waistcoat, air caves can be formed below snow drifts, enough air exists in the airbags, and enough buoyancy can be formed during or after snow slide to enable the head of a wearer to be always above snow and reduce injuries of his / her body; moreover, the air in the airbags can enable the wearer to breathe for 2-3 hours, so that survival time of the wearer is prolonged, more time for excavating and searching is gained, and survival rate after the wearer is buried due to the snow slide is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of outdoor products and relates to a protective vest. Background technique [0002] When the cohesive force inside the snow cannot resist the gravitational pull it receives, it slides down, causing a large number of snow bodies to collapse. People call this natural phenomenon an avalanche. Avalanches are a serious threat to climbers, local residents and tourists. Among the dangers encountered in alpine expeditions, the damage caused by avalanches is the most frequent and tragic, often causing "annihilation of the whole army". People killed in avalanches account for 1 / 2 to 1 / 3 of all alpine deaths. At present, most of the protective vests sold on the market have hard shells to reduce the damage caused by avalanche impacts to people's bodies. Due to their large protection range and heavy weight, this kind of protective vests greatly increases the body load and makes it difficult for people to walk in snowy m...
