Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a backpack type air bag system for a harness-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack type air bag system of a harness type safety bag, and more particularly, to a back bag type air bag which is applied to a safety table (harness type safety table) stipulated in the Industrial Safety & Type airbag system of a harness-type safety stand capable of effectively protecting an operator's body according to the present invention.

Generally, in various civil engineering and construction sites such as high-rise building construction site, industrial facility construction site, high-rise bridge construction site, etc., workers are performing work at the job site, and the most important safety management factor Is a worker 's fall accident, and most of the fall accidents are linked to the death of the worker and the central part.

Accordingly, the safety device prepared for the fall of the worker at the job site is provided by various methods and means. In most cases, by connecting the worker's body and the job site with the rope, it is possible to prevent falling at the time of fall, Safety nets, etc., are installed to prevent falling when they fall.

However, in the above case, in the case where the operator does not tighten the rope for safety when the carelessness of the worker or the worker's work is hindered, or the work site is difficult to attach a safety device such as a mesh due to the structural characteristic of the worksite, There is a problem that the safety management for the vehicle is insufficient.

In addition, when a large-scale apartment construction site, a large-scale bridge civil engineering work site, etc. are widespread and there are many workers, the manager can not immediately recognize the fall of the worker and the post- And the mortality rate is increasing.

In order to solve the above-mentioned problems, safety vests for workers equipped with airbags have recently been developed in order to prevent deaths and serious injuries in the event of a worker's fall, 04), when the case for installing the gas generator for an air bag is worn, the front and rear sides of the body are wrapped like a vest, and they are connected to each other using a connecting means to maintain a form that can be worn like a vest A gas generating device is installed inside the case, and an airbag as known in the art is installed on the outer surface of the case protruding from the outlet of the gas generating device. And a gas generating device is installed at the upper end of the case in the form of facing upward, There is known a crash safety vest comprising a lock airbag provided to protect the head portion and a signal generating means known as means for operating the gas generator of the airbag.

In Korean Patent No. 10-0805656 (Feb. 14, 2008), airbag cases for protecting the body and head are arranged at the front and back of the safety vest, and known airbags connected to the gas generating device are folded Wherein the safety vest has a shoulder portion at the back of the safety vest, and the parachute type tube is connected to the rope to house the safety vest.

In addition, Korean Patent No. 10-1207012 (Nov. 26, 2012) discloses an airbag inflator which is an airbag of a shape that can protect a body part of a worker, An inflator drive switch unit which is a switch for fluidly opening and closing the inflator inflator and a control unit for emitting an electric signal for driving the inflator drive switch unit, And a main control unit housed in the case, respectively; The main control unit may include a comparator for comparing the sensed output from the fall sensor unit, which is an acceleration sensor, with a reference value to be set, and a comparator for comparing the GPS position value And a driver for emitting a signal for driving an inflator bag in a fall state, and a signal from the GPS position transmitter according to a fall response signal from the main controller And a crash control unit that cooperates with a remote control unit that performs a function of displaying a fall position value, displaying a fall position on an operation site map, and alarming a warning light or an alarm on the monitor.

However, the falling-cost safety vests or safety vests of the above patents are those in which the airbag is applied to a general vest form, which does not correspond to the safety vest (harness-type vestibule) according to the Industrial Safety and Health Act In particular, the above-mentioned safety vests include a U-shaped hanger, a safety block, and a fall prevention device, which are specified in the Industrial Safety and Health Law and the Standard Safety Work Guidelines for Falling Disasters There is a problem that it can not be used at a high worksite such as a construction site or a civil work site because a connection link (connection link) for connection is not provided.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2007-0115990 (December 06, 2007) discloses a pair of shoulder belts crossing at the back of a human body and hung on both shoulders, And a connecting portion capable of connecting a rope to an intersection of each of the shoulder belts. The harness type safety belt according to any one of claims 1 to 3, characterized in that the belt comprises a pair of annular femoral belts And a control means for inflating the airbag when the fall of the human body is detected by the fall detection means. The airbag according to claim 1, Is known.

However, the harness type safety belt is a safety swing type safety harness (harness type safety system) stipulated in the Industrial Safety and Health Law and the Standard Safety Work Prevention against Falling Disaster, and can be used in construction and civil engineering sites. However, There is a problem in that it can not be applied to a safety belt (harness type safety belt) which is used in the past because it is unified so as not to be used in a conventional safety swing type safety harness (harness type safety belt).

In addition, in the case of the conventional harness-type safety belt described above, since the airbag can be partially applied only to the neck peripheral portion and the waist portion of the worker, the process of separately producing the safety belt is complicated and productivity is deteriorated. So that there is a problem that the actual safety due to an operator crash is insufficient.
