  The present invention relates to a helmet headband and a helmet using the same, and more particularly to a helmet headband having a sweat absorbing function and a helmet using the same.

  2. Description of the Related Art Conventionally, various helmets having a sweat absorbing function on a headband have been provided for the purpose of treating sweat generated on the head. The sweat-absorbing member can be attached and detached, and the removed sweat-absorbing member can be replaced with a washed one or a new one so that it can always be comfortably worn. Conventionally, a helmet headband has a structure that can be replaced with a cap body when there is an abnormality such as breakage, but a soft synthetic resin is mainly used.

  For example, in Patent Document 1, a water absorbent sheet is detachably provided on the inner surface side from the front head contact portion of the soft synthetic resin headband to the tip of the heel provided on the cap body. Is a cloth, non-woven fabric, leather or synthetic resin, and further discloses that a non-absorbent sheet is laminated on a water-absorbent sheet.

  Patent Document 2 discloses a helmet in which at least one sweat absorbent cloth made of a nonwoven fabric is detachably attached to a hammock or a headband. Further, in order to form a ventilation part in the part of the hammock or headband to which the sweat absorbent cloth is attached, or to provide a function of preventing sweat and wetting on the skin side of the sweat absorbent cloth, a nonwoven fabric is used as the sweat absorbent cloth. It is disclosed that a resin film having air permeability and liquid permeability is formed on the skin side surface.

  Patent Document 3 discloses a helmet in which a sweat absorbing member can be attached to and detached from an auxiliary band that can be attached to and detached from the headband inside the helmet body. More specifically, the auxiliary band has attachment portions formed at both ends in the longitudinal direction, and the attachment portions can be attached to and detached from the headband by engaging the attachment portions with the engagement portions on both side heads of the soft synthetic resin headband. The attachment position of the auxiliary band to the headband can be adjusted by changing the locking position, and the sweat absorbing member is formed in a cylindrical shape that can be inserted through the auxiliary band with a material excellent in sweat absorbing properties such as towel cloth, It can be attached to the band by inserting the auxiliary band, and can be removed from the band by removing the auxiliary band.

  Patent Document 4 discloses that a wearing tool provided on a plate formed in a horizontally long curved shape can be fixed to a headband made of a soft synthetic resin of a helmet, and a sweat absorbing member is attached to the plate on the concave side of the plate. A helmet that is detachably provided is disclosed. Examples of the sweat absorbing member include a water-absorbing material, for example, a towel made of a plurality of towel cloths stacked in a pad shape, and a bag made of a water-permeable material encapsulated with a highly water-absorbing polymer. Yes.

However, most conventional helmets have a structure in which a sweat absorbing member is detachably attached to a soft synthetic resin headband, and the sweat absorbing member removed from the headband is washed or replaced with a new one. However, since it is composed of two members, a headband and a sweat absorbing member, and three members when an auxiliary band is used, the cost is high. In addition, conventional helmets have their heads tightened and held by size adjustment mechanisms provided at both ends of a soft synthetic resin headband, and at that time, the sweat-absorbing part attached to the portion corresponding to the substantially front half of the headband The pad is interposed in the forehead to provide cushioning. Since the headband does not expand and contract by itself, in order to securely hold the helmet on the head, it must be tightened quite tightly, and the feeling of pressure on the head due to prolonged use is painful.
