摘要:
Grommet (10, 50, 60) coupled to a shell (2) of a helmet (1), the grommet (10, 50, 60) forms a vent in the helmet (1) to draw outside air into the helmet (1). The grommet (10, 50, 60) includes a base (11, 62), an operation member (12, 66), and a plurality of shutters (13, 64). The base (11, 62) is configured to be coupled to the shell (2) of the helmet (1) where a through hole (4) is located. The base (11, 62) has an opening that overlaps the through hole (4) when the base (11, 62) is coupled to the shell (2) of the helmet (1) where the through hole (4) is located. The operation member (12, 66) is rotatably coupled to the base (11, 62). The plurality of shutters (13, 64) is configured to open and close the opening when the operation member (12, 66) is rotated relative to the base (11, 62).

A method for adjusting the comfort level of a helmet includes the steps of acquiring head shape data (S102) by measuring a three-dimensional shape of a head of a wearer of a helmet 1, inputting inner surface shape data (S104) showing a three-dimensional shape of a helmet inner surface 1a, acquiring space information (S108) showing a space between the head and the helmet inner surface 1a on the basis of the head shape data and the inner surface shape data, and displaying (S110) additional images showing the space information on a display part 13 by superimposing the additional images on i) a shape image showing the inner surface shape data or ii) the shape image showing the head shape data and the inner surface shape data.

The invention provides for a helmet (1) includes the first pad in contact (9) with an occipital region of a rider, and each of second pads (7) in contact respectively with the cheeks of the rider, and wherein the first pad can move in the helmet from a first occipital region-contact position to a second occipital region-contact position, and wherein the second pad can move in the helmet from a first cheek-contact position to a second cheek-contact position, and wherein the helmet can be moved relative to the rider's head by a predetermined distance.
摘要:
By inputting an upper head size (Z) to a computer in addition to a front & back length-size (X) and a right & left width-size (Y) of a head portion (94) of a helmet wearer (93) and by data-processing them, there is employed a configuration in which a kind of the helmet size and a shape of a pad (131, 134 to 137, 141 to 147) such as a pad (143 to 145), in the region consisting of the head-top portion and the vicinity thereof, or the like, which fit the head portion (94) of the helmet wearer, are to be selected. It is possible to provide a selection method in which it is possible to easily select a kind of a preferable size of the helmet, and a preferable shape of the pad in the region consisting of the head-top portion and the vicinity thereof.
