Abstract: In a helmet including a battery and a helmet body whose outer surface is constituted by a shell, a charging connector is disposed inside the shell to face inward of the shell, and the charging connector is configured to be connected to a power supply-side connector connected to a power supply through a power supply-side cable during charging of the battery.
Abstract: A helmet which performs good ventilation and which is capable of mitigating the uncomfortable feeling due to sound is provided. The shock absorbing liner includes front ventilation holes to communicatively connect the front openings to the inside of the shock absorbing liner, outside air paths disposed in a space on an outer side relative to an inner surface of the shock absorbing liner, and communicative holes to communicatively connect the inside of the shock absorbing liner to the outside air paths. The outside air paths include primary flow paths disposed to be connected to the rear opening and secondary flow paths. The communicative holes communicatively connects positions on an outer surface of the shock absorbing liner except positions of the primary flow paths, to the inside of the shock absorbing liner. The secondary flow paths are disposed to connect the communicative holes to the primary flow paths.
Abstract: A good fitting sensation of a lens unit is obtained by performing fine adjustment of the position and angle of the lens unit. A lens unit attachment mechanism includes a frame member supporting a pair of lenses, side frame members extending rearward of the lenses from left and right end portions of the frame member, an angle adjustment member coupled to the lens unit and having two rotation pivot points, and a position adjustment retention member retaining the angle adjustment member so as to allow extending and retracting. The lens unit attachment mechanism adjusts the position and angle of the lens unit flexibly.
Abstract: A helmet includes an operation mechanism, which is accommodated in an accommodation portion, on an outer shell of the helmet for operating an anti-glare visor with a transmission cable. One wall surface at an end of the accommodation portion in an operation direction defines an end surface including an insertion hole extending through the outer shell for passage of the transmission cable.
Abstract: Plural contact pieces of a shaft member, which is mounted to a helmet main body, abut a cam surface that is formed at a hole portion provided in a proximal end portion of a chin guard. When the chin guard is rotated from a fully closed position to a fully open position with respect to the helmet main body, at least one of the contact pieces abuts an anchor surface, and, simultaneously, at least another one contact piece fits into a concave portion, and, due thereto, the chin guard is fixed with respect to the helmet main body.
Abstract: An aerodynamic control device includes a void opening. The void opening decreases a resistance of a turbulence generated by a component part located behind a center of a longitudinal width of a helmet and is formed so that one end is connected to the helmet and the other end protrudes backward from the helmet.
Abstract: A helmet that can effectively reduce the rotational acceleration of an impact and at the same time also effectively reduce translational acceleration is provided. A helmet has an outer shell comprising a hard material and a shock absorbing liner (14) disposed inside the shell. The shock absorbing liner (14) comprises a main body liner (16), a recessed portion (30) provided at an inner surface of the main body liner (16), an insert liner (18) fitted into the recessed portion (30), and a central raised portion (42) (central support member) disposed between a bottom surface of the recessed portion (30) and a bottom surface of the insert liner (18). When the helmet receives an impact, the insert liner (18) swings about the central support member as a fulcrum, thereby reducing the impact.
