Claims6

Dependent claims

A helmet shield coupled to a front opening of a helmet, the helmet shield comprising:

a lens unit provided to face a front portion of the front opening;
a frame unit provided along a perimeter of the lens unit;
and
a ventilation unit provided at distal ends of the lens unit, the ventilation unit providing for fluid communication of air between an inside and an outside of the helmet shield, wherein the ventilation unit includes:
a ventilation hole, and a guide unit coupled to an outer surface of the helmet shield to cover the ventilation hole;
wherein the lens unit includes:
a first lens configured as one single body with the frame unit, the first lens protrudes from the frame unit toward a front of the helmet shield, and
a second lens coupled in an inside direction with respect to the first lens, the second lens further protrudes toward a front of the helmet shield with respect to the frame unit,
wherein the ventilation hole is located through a part of the first lens and a part of the frame unit at a boundary between the first lens and the frame unit, and wherein a first part of the ventilation hole through the first lens faces a rear outside of the helmet shield along an inner surface of the second lens and a second part of the ventilation hole through the part of the frame unit faces a vertical direction with respect to the helmet shield, and
wherein the guide unit includes:
a cover unit provided at a distance from the ventilation hole to cover the ventilation hole;
a guide hole formed at a rear outside of the cover unit for fluid communication of air between the ventilation hole and the rear outside of the helmet shield;
a lens unit connector configured to connect the cover unit to a side edge of the lens unit;
and
a fixing ring provided at the cover unit for coupling the cover unit and the frame unit, the fixing ring configured to be inserted into a fixing hole formed, separately from the ventilation hole, by removing a part of the frame unit.
