Title:
IN-HELMET VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/235307
Kind Code:
A1
Abstract:
When a helmet 1 to which an in-helmet ventilation device 100 is attached is worn, an edge on a first sheet 11 side of an opening a of a bag-like body 10 comes into contact with an outer surface of the helmet 1, whereas an edge on a second sheet 12 side of the opening a of the bag-like body 10 comes into contact with the head of a user, and this configuration makes it easy to maintain a state in which the opening a of the bag-like body 10 is opened. In particular, a belt-like sheet 13 connected to the second sheet 12 of the opening a of the bag-like body 10 is configured to draw an upper edge of the second sheet 12 into the helmet 1; therefore, it is possible to suitably maintain the state in which the opening a of the bag-like body 10 is opened. In other words, it is possible to suitably feed air into the helmet 1, the air being taken into the interior of the bag-like body 10 by means of a fan 30 and discharged from the opening a, and thus to suitably ventilate the inside of the helmet 1.
