Description

Helmets, especially full-face helmets

technical field

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

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.

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 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 pad.

One object of the present invention is to provide a helmet comprising a filter which allows better protection of the person wearing the helmet in areas with highly polluted air.

Contents of the invention

In one aspect of the invention, this object is achieved by a helmet, in particular a full-face helmet, comprising: an outer shell; a lower opening within the outer shell that covers the head of the person wearing the helmet and accommodates Neck of a person in a helmet; closed or closable visor; air intake opening in the outer shell for intake of air, preferably under the visor; air filter element ventilation insert adapted to receive inside the shell The receiving space, the air intake opening allows air to flow from the outside of the outer housing to the receiving space; and a removable air filter element, which preferably includes a pleated filter bellows made of filter media, wherein the air filter element is hermetically positioned within the receiving space.

An advantage of using a pleated filter element inside the shell of the helmet allows for a larger filter media area. Therefore, the media can be selected to have a higher filtration rating because as the filter area increases, the restriction on the filter decreases.

The filter medium can preferably be selected from media having a filter class G1, G2, G3, G4, M5, M6, F7, F8, F9 according to EN 779. Filter media can include single or multi-ply paper, woven or non-woven filter media. Media can include multilayer woven media, man-made non-woven media, cellulose media, paper media laminated with fine or nanofiber layers, activated carbon particle layers, laminated paper media layers, or glass fiber blended paper, non-woven or Fabric, or consisting of it.

In one embodiment, the helmet further includes an air intake grill disposed over the air intake opening. This protects the air intake opening from larger objects such as insects entering the air intake opening.

In an advantageous embodiment, the air filter element comprises a hydrophobic filter medium layer. This medium preferably faces the air intake opening. In this way, the amount of moisture entering the inside of the helmet can be reduced.

Preferably, the air filter element comprises sealing means for sealingly contacting the receiving space. The sealing means can be provided as a molded bead, in particular made of polyurethane, surrounding the air filter element, or as a woven or non-woven side covering the side edges of the air filter element and adapted to abut against the side wall of the receiving space bring.

In an advantageous embodiment, the air filter element comprises activated carbon in order to reduce the amount of harmful substances entering the helmet. The filter media can be used as described in US 2014/0013957 A1, WO2015/091822 A1, US 2014/0157990 A1, EP1882511 A2, which are incorporated herein to the fullest extent permitted by law.

In another aspect of the invention, this object is achieved by a helmet comprising: an outer shell; a lower opening in the outer shell, which preferably surrounds a person's neck when the helmet is worn by the person; An annular layer covering the lower opening is connected to the outer shell at the edge of the lower opening and surrounds an inner opening which is preferably adapted to seal against the neck of a person wearing the helmet. By sealing the neck area, it is possible to avoid air entering the helmet other than through the filter element, thus making the filtering effect more effective.

In a preferred embodiment, the annular layer comprises a soft pad attached to the edge of the inner opening of the annular layer. A soft pad is adapted to abut the neck, thereby sealing the inside of the helmet from the outside.

In one embodiment, the annular layer comprises or consists of a textile, in particular an air-impermeable textile. In this way, air entering the helmet through the fabric can be avoided or reduced, making the filtering effect more effective.

In a preferred embodiment, the annular layer comprises a cut-out area extending radially from the inner opening to the outer area of the annular layer, in particular to the outer casing. Therefore, it is convenient to carry a helmet. Preferably, closure means are provided to close the incision area when the helmet is on the person's head. It is further preferred that the closure means comprises a zipper and/or a hook and loop fastener.

In one embodiment, the helmet has one or more air intake openings, in particular two air intake openings, for each air intake opening there may be a separate filter element, for example a pleated filter element, or There may be one filter element for more than one air intake opening.

The helmet according to the invention can be used as a motorcycle helmet, a racing helmet, a full face helmet, a mining or construction site helmet, a firefighter's helmet or for other purposes where a full face helmet can be used.
