## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a functional headband that is applied to welding masks, protective masks, safety helmets, medical helmets, etc. and, more particularly, to a functional headband having an integral cushion band which is formed at supporting bands, thereby supporting a wearer's head in a double supporting structure.
Description of the Related Art
In general, industrial safety equipment, such as welding masks, protective masks, safety helmets, etc., and medical safety equipment, such as medical head guards, medical safety helmets, etc., are commonly used in various industrial (e.g. construction or civil engineering) and medical sites, in order to protect a worker or a wearer from any accident while working.
In one example, a welding operation generates a strong flash of light and causes welding material to be scattered toward the welder's face. A welding mask has been used as a representative example of safety equipment to protect the welder's eyes and face from the aforementioned dangers.
A welding mask generally includes a protective mask configured to cover a welder's face along with a viewing window to protect the welder's eyes and face, and a headband provided inside the protective mask to help the welder stably wear the protective mask on the head.
Such a headband includes a main band configured to surround the circumference of the wearer's head in the state of closely contacting the forehead, and a first supporting band and a second supporting band configured to surround the front section and the rear section of the head. The headband further includes a length adjustment lever, which is positioned on the rear section of the wearer's head and is connected with the main band through adjustment bands. That is, the adjustment bands are directly connected with the ends of the main band, and are coupled to the length adjustment lever.
A cushion member is attached to an inner surface of the length adjustment lever. The cushion member is centrally concave from upper and lower and left and right sides thereof so as to come into close contact with the rear section of the head. Such a cushion member comfortably surrounds the rear section of the wearer's head, thereby providing comfort and convenience in wearing a welding mask.
However, because the first supporting band and the second supporting band are in direct contact with the specific regions of the wearer's head, the wearing sensation is deteriorated. Further, when the wearer wears the headband for a long time, he or she feels uncomfortable and even develops a headache because of the pressure that is continuously applied to the specific regions of the head by the first supporting band and the second supporting band.
To solve this problem, the wearer temporarily puts an intervening member, constituted of a sheet of paper, cloth, etc., between the head and the first and second supporting bands so as to prevent the first and second supporting bands from intensively pressing the specific regions of the head.
However, the intervening member, constituted of a sheet of paper, cloth, etc., is often separated without being fixed between the head and the first and second supporting bands. Therefore, it is inconvenient for the wearer to put the intervening member back between the head and the first and second supporting bands while working, which obstructs work and deteriorates work efficiency.
Further, whenever the wearer takes off the headband, for example for a rest, and puts the headband back on to resume a work, he or she is inconvenienced by having to remove and remount the intervening member. Furthermore, the intervening member, made of a sheet of paper or cloth, may be easily lost if the wearer is careless.
SUMMARY OF THE INVENTION
The present invention is devised to solve the above problems, and it is an object of the present invention to provide a functional headband having an integral cushion band which is formed at supporting bands to assist in supporting the wearer's head, thereby facilitating mounting/demounting and replacement of the headband to/from industrial safety equipment, such as welding masks, protective masks, safety helmets, etc., and medical safety equipment, such as medical head guards, medical safety helmets, etc., easily supporting the whole region of the head, minimizing the pressure and acting as a buffer by dispersing the weight and load of the aforementioned safety equipment, and enabling the headband to be easily fitted on the wearer's head and to be securely maintained in close contact with the head regardless of the shape and size of the wearer's head.
In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a functional headband having an integral cushion band, the functional headband including a main band configured to be worn on a wearer's head, supporting bands connected with the main band and configured to be placed on the wearer's head, adjustment bands connected with both ends of the main band and configured to be adjusted in length, a length adjustment lever configured to adjust the length of the adjustment bands, and cushion bands formed integrally at the supporting bands to cover the wearer's head, thereby supporting the wearer's head in a double supporting structure.

Further, as shown in FIGS. 6 and 7, the cushion band formed at the first supporting band 31 and the cushion band formed at the second supporting band 33 may be connected to each other, thereby supporting the wearer's head in a double supporting structure and providing a comfortable headband-wearing sensation.
Further, as shown in FIGS. 9 and 10, the cushion band formed at one part of the second supporting band 33 and the cushion band formed at the other part of the second supporting band 33 are connected to each other, thereby supporting the wearer's head in a double supporting structure and providing a comfortable headband-wearing sensation.
Each of the cushion bands may be formed with one or more openings 72-1 as shown in FIG. 8, thereby supporting the wearer's head in a double supporting structure and providing a comfortable headband-wearing sensation.
Preferably, the cushion bands 70 and 70′ may be made of an elastic material so as to change in shape when external force is applied thereto and return to the original shape thereof when the external force is removed therefrom.
The cushion bands 70 and 70′, which come into contact with the wearer's head when he or she puts on the headband 100, are formed with one or more openings 72 and 72′.
The openings 72 and 72′, which are formed in the cushion bands 70 and 70′, function to increase the region of the cushion bands 70 and 70′ that supports the wearer's head while reducing the contact area between the cushion bands and the head. Accordingly, a comfortable wearing sensation is achieved. Further, the weight and load of the welding mask are dispersed, thereby remarkably relieving pressure and pain applied to the central region of the wearer's head, which contacts the cushion bands 70 and 70′.
Furthermore, the openings 72 and 72′, which are formed in the cushion bands 70 and 70′, function to enable the headband 100 to be easily fitted on the wearer's head and securely maintained in close contact with the head regardless of the shape and size of the wearer's head, and function to avoid contact between the cushion bands 70 and 70′ and the central region of the head, which is known to be susceptible to pain, and function to improve air ventilation, thereby preventing the wearer from sweating excessively even when he or she wears the headband 100 for a long time.
Preferably, the cushion bands 70 and 70′ may have soft parts, which are made of a soft material and are provided on the bottom surfaces of the cushion bands 70 and 70′, which come into contact with the wearer's head. When the wearer wears the headband 100, the soft parts provided on the bottom surfaces of the cushion bands 70 and 70′ contact the wearer's head, thereby minimizing the pressure that is applied to the head by the weight and load, and preventing the cushion bands 70 and 70′ from being taken off.
