INNER CELL FOR SAFETY HELMET AND SAFETY HELMET WITH THE SAME}

The present invention relates to a hard hat inner end detachable inside the helmet and a helmet having the same.

Generally, a safety helmet is worn for workers' safety at a construction site or a work site such as a factory. The helmet is worn on the worker's head to reduce the impact of the shear from the falling object to the worker, and protects the worker's head to prevent human accidents.

In addition to the function of protecting the worker's head, the hard hat needs to minimize the deterioration of workability by increasing the fit and reducing discomfort. These, hard hats are largely divided into a hard case-shaped outer shell member and an inner shell member installed inside the outer shell member to absorb sweat.

The endothelial member is made of an integral or separate type with a cushion member that provides a cushion between the helmet and the worker's head to absorb sweat generated from the head and forehead, thereby enhancing operator convenience and workability.

As a conventional helmet-related endothelial technology, in the registered patent No. 0969916 (Patent Document 1), the mesh endothelium 20 and the sealing portion 30 containing the superabsorbent polymer powder are formed at the intersection, and the mesh endothelium 20 and the sealing portion Functional endothelial connecting 30 to elastic finishing cloth 50 is disclosed. In addition, Patent No. 1290323 (Patent Document 2) discloses a endothelium for safety helmets in which a predetermined distance C is formed between the bottom of the central portion of the headrest band 4 and the top of the central portion of the head cover 10. In the utility model registration No. 04779141 (Patent Document 3), a space keeping member 140 that spaces the gap between the outer shell 110 and the inner shell 130 and an adjusting unit 150 for adjusting the circumferential length of the inner shell 130 are provided. A hard hat is disclosed.

The mesh endothelium 20 of patent document 1 and the head cover 10 of patent document 2 have a hemispherical structure and are elastically placed (elastic band) to cover the user's head tightly. There are problems that can occur.

In Patent Document 3, the elastic means (elastic band) is removed by providing the adjusting part 150 for adjusting the circumferential length of the endothelium 130, but the entire part of the endothelium 130 is in direct contact with the user's head and is breathable. It fell and could not effectively disperse the weight of the hard hat.

Due to this, when the user wears the helmet, the weight received from a portion of the head is distributed, thereby improving the wearing feeling and the pressure of the helmet.

In addition, the first endothelial member and the second endothelial member are formed with non-contact opening portions along the rear end of the contact rod portion and the contact rod portion, respectively, in contact with each other. The end portion of the second endothelial member is in close contact, thereby enhancing the wearability of the user's hard hat.

In addition, the second endothelial member protrudes from the lower surface of the first endothelial member and has elasticity, so that the second endothelial member can function as a cushioning material to alleviate external impact.

In addition, since a ventilation passage is formed due to a difference in thickness between the first endothelial member and the second endothelial member, air circulation between the part where the first endothelial member is formed, that is, before and after the user's head, can reduce sweat generated in the center of the head. Moreover, sweat can be easily absorbed around the forehead and neck through the third and fourth endothelial members.
