Description

Seat belt experience device {SAFETY BELT EXPERIENCE DEVICE}

The present invention relates to a seat belt experience apparatus, and more particularly, to lift a seat belt worn by a first person first, and when a predetermined reference weight is sensed, by lifting the experience person to a position spaced from the ground, the human body of the experienced person. Is stably supported by the seat belt, so that the experienced person can rapidly rise at a speed of 1m-2m per second to a position spaced from the ground to feel the descent, and depending on the type of seat belt (whole, upper body waist belt) The present invention relates to a seat belt experience device that can induce a different experience, inducing the most secure overall belt wearing.

In general, there are a variety of risk factors at the construction site, which requires special attention.

In particular, when working on a railing of a building or the like, it is exposed to the risk of safety accidents such as falling due to carelessness of an operator or falling of a railing or form of a building by a collapse.

Conventionally, safety belts are used to prevent the fall of workers at the construction site, and safety training for workers is periodically performed, but they still fall down from high places while working without wearing the seat belt. Accidents occur frequently.

Therefore, in the prior art, by constructing a safety education construction structure, allowing the worker to experience the situation that actually falls, to recognize the importance of wearing the seat belt, to actually encounter the risk of falling accidents due to the work around the safety education To increase the effect.

However, the conventional safety education temporary structure has a risk of a safety accident even in the process of experiencing the actual fall situation, it was not efficient because it takes a lot of cost to manufacture the temporary structure.

The object of the present invention is to first lift the seat belt worn by the experienced person by operating the first drive unit, and to operate the second drive unit only when a predetermined reference weight is sensed to raise the experienced person to a position spaced apart from the ground. When the human body is stably supported by the seat belt, the experienced person can rapidly rise at a speed of 1m-2m per second to a position spaced from the ground, and can feel the descent, depending on the type of seatbelt (full type, upper body type) Waist Belt) The compression strength felt at the lumbar spine enables a different experience, providing a seat belt experience device that can induce the safest overall belt wearing.
