Description

The present invention relates to a pad used for a harness type safety belt.

At work sites in high places, it is obligatory to wear a safety belt, which is also called a fall prevention device, in order to prevent workers from falling accidents. Safety belts are roughly divided into torso belt type and harness type. The harness-type safety belt is provided with a shoulder belt and a thigh belt, and as compared with the body belt-type safety belt, the drop impact load at the time of preventing a fall is dispersed, and damage to the body can be reduced. In addition, a worker wearing a harness-type safety belt can wait in a stable posture until he / she is rescued after the fall is prevented. For this reason, harness-type safety belts are now used in principle.

At the work site, it is common for workers to wear a torso belt for hanging various tools and tool bags. Since a wide variety of tools and the like are suspended from this body belt, it is preferable that the body belt is stably wound and held around the waist of the operator. In particular, when many tools or heavy tools are hung, the torso belt may slip down from the waist, which not only reduces workability but also may cause the tools to hit people or objects around them. Therefore, conventionally, the torso belt is configured as a part of the harness type safety belt, and a part of the load applied to the torso belt by attaching a tool or the like is released to the shoulder belt to stably wind and hold the torso belt. Is known (see Patent Document 1).

By the way, the worker often works not only at a high place but also at a place where the use of a harness type safety belt is unnecessary. However, since the above-mentioned harness type safety belt is integrated with the torso belt, a separate torso belt is attached when the harness type safety belt is removed, and various tools are attached to the separate torso belt from the harness type safety belt. It was not convenient because it was necessary to move the belt and the tool bag.

Therefore, the worker wears a single body belt and, if necessary, a harness-type safety belt in which the body belt is not integrated. However, in order to stably wind and hold the single torso belt around the worker's waist, it is necessary to tighten the torso belt tightly to the worker's waist, which may cause the worker to feel excessive pressure. There was a problem that it became difficult to bend and stretch the waist.

A pad body including a shoulder support portion located along the back support portion, passing through the wearer's shoulder and extending over the wearer's chest, and extending downward from the back support portion of the pad body, the wearer. It is characterized by being provided with a hanging belt for a body belt that is detachably connected to the body belt to be worn by the body and suspends the body belt.

According to the present invention, a part of the load applied to the torso belt is released to the shoulder rest of the pad by connecting the hanging belt extending from the pad interposed between the harness type safety belt and the wearer to the torso belt. Can be done. This makes it possible to stably wind and hold the body belt without tightening it. In addition, the hanging belt for the torso belt is not attached to the harness type safety belt, but to the harness type safety belt and the removable pad, so the conventional harness type can be used without modification to the harness type safety belt. You can continue to use the safety belt.
