Abstract
A helmet is provided which is to be worn on the head of a helmet wearer and can be removed from the head with a comparatively small force. Operation for removing the helmet, including preliminary operation for it, can be performed easily and quickly. A recess-projection engaging mechanism to attach a blockish inside pad to a head protecting cap portion side includes an engaging pin on the inside pad side or head protecting cap portion side, and a notched engaging hole on the head protecting cap portion side or inside pad side. When pulling the inside pad outward from inside the head protecting cap portion at least partly, the engaging pin moves relative to outside the engaging hole through a notch of the engaging hole.
Claims25
A helmet comprising a head protecting cap portion with one or a plurality of blockish inside pads disposed therein,
- said helmet further comprising one or a plurality of connecting mechanisms to attach at least one of said blockish inside pads to said head protecting cap portion,
- wherein at least one of said connecting mechanisms comprises a recess-projection engaging mechanism including one of an engaging pin and a notched engaging hole disposed on said at least one blockish inside pad side, and a corresponding one of a notched engaging hole and an engaging pin disposed on said head protecting cap portion side,
- when said at least one blockish inside pad is disposed in said head protecting cap portion, said engaging pin is configured to engage with said engaging hole, and
- when pulling said at least one blockish inside pad outward from inside said head protecting cap portion at least partly, said engaging pin moves forward relatively to outside said engaging hole through a notch of said engaging hole.
A method of removing, from a head of a helmet wearer, a helmet comprising a head protecting cap portion with one or a plurality of blockish inside pads disposed therein,
- at least one of the blockish inside pads being attached to the head protecting cap portion in advance by one or a plurality of connecting mechanisms,
- wherein the method comprises, when attaching the at least one blockish inside pad, using, as at least one of the connecting mechanisms, a recess-projection engaging mechanism including one of an engaging pin and a notched engaging hole disposed on the at least one blockish inside pad side, and a corresponding one of a notched engaging hole and an engaging pin disposed on the head protecting cap portion side to be able to engage with one of the engaging pin and the engaging hole,
- when removing the helmet worn on the head of the helmet wearer, first, pulling the at least one blockish inside pad outward from inside the head protecting cap portion to cause the engaging pin to relatively come out from the engaging hole through a notch of the engaging hole, thus disengaging the engaging pin from the engaging hole, and pulling the blockish inside pad outward from inside the head protecting cap portion at least partly, and
- removing the head protecting cap portion from the head of the helmet wearer.
