AI Technical Summary

Problems solved by technology

Since the area of ​​the filter is geometrically limited, the filter cannot be very effective, otherwise the breathing resistance would be too high
Additionally, helmets have other openings that allow air to enter the helmet, reducing the efficiency of the filter pads

Abstract

Helmet, especially full face helmet (1), comprising an outer shell (4), a lower opening (3) in the outer shell (4), a closable visor (2), an air intake opening (5) in the outer shell (4) for breathingair, a receiving space (6) adapted to receive an air filter element (7) inside the shell, the air intake opening (5) allowing air to flow from the outside of the outer shell (4) to the receiving space (6), and a removable air filter element (7), wherein the air filter element (7) is sealingly positioned in the receiving space (6).

Description

technical field [0001] The present disclosure relates generally to helmets, particularly motorcycle helmets, especially full face helmets. The present disclosure further relates to helmets, particularly motorcycle helmets, including an air filter for the inhaled air of the person wearing the helmet, and to helmets having a non-breathable fabric or the like that closes to accommodate wearing The lower opening of the helmet is the neck of the helmet. Background technique [0002] Motorcycle helmets are well known in the art. One type of helmet is the full face helmet, which covers the entire face of the wearer. Full face helmets typically include an outer shell with two main openings, with a front opening that can be covered by a visor and a lower opening that covers the wearer's head and accommodates the wearer's neck. [0003] WO publication WO 99 / 62364 A1 shows a full face helmet comprising a flat filter pad under the visor area of ​​the helmet. Since the area of ​​the ...
