Support band for the forehead for helmets and helmet provided with said support band for the forehead

摘要

Forehead support band (1) for helmets (3), in particular helmets (3) for work or sports protectors, comprising an elongated structure (2), preferably flexible, capable of assuming an arched configuration in the mounted state in a helmet (3), in which said structure (2) has a first part (4) destined to be permanently located, from the inside, in front of the front part (3a) of a helmet (3) in which it is mounted said forehead support band (1) and a second part (5) adapted to engage a user's forehead while using said helmet (3); wherein said parts (4, 5) of said structure (2) are detachably coupled, and can be decoupled to allow separation thereof or temporary removal of said second part (5) or replacement of said second part (5) with another second part (5) identical to the withdrawal or different from the withdrawal, wherein said front support band (1) comprises coupling means (8) operatively interposed between said first part (4) and said second part (5) of said structure (2) to allow both the joining of said parts (4, 5) and the decoupling of said parts (4, 5) when necessary, characterized in that said coupling means (8) they comprise a plurality of protuberances (9) each having at least one coupling part (9a) having an enlarged section and a plurality of seats (10) each having an elastically flexible coupling edge (10a), in the that each bulge (9) can be i inserted into a respective seat (10) and can be removed therefrom using the elastic capacity of the coupling edge (10a) of the latter, in which said coupling means (8) comprise a protuberance (9 ') and a centering seat (10 ') each arranged respectively at the midpoint of the respective part (4, 5) of said structure (2), wherein the coupling edge (10a') of the centering seat (10) delimits an opening for the respective centering protrusion (9 ') that does not allow said centering protuberance (9') to move transversely, that is, which allows the centering protuberance (9 ') to slide along the development longitudinally of said parts (4, 5), the seats (10) of the coupling means (8) are arranged on one side and on the other with respect to the centering seat (10 ') they define, in the body (4a , 5a) of the respective part (4, 5) of said structure (2), respective slots that are they develop along the longitudinal development of the respective part (4, 5), in which each slot allows the sliding of the respective protuberance (9) in order to allow changing the structure (2) and the band (1) of forehead support between a substantially straight state and an arched state.
