Abstract
Description
- This invention relates to a helmet, and more particularly to a helmet with ventilation for controlling the formation of fog on a shield thereof, and for respiration of a person wearing the helmet.
- Helmets are well known, and are commonly used to protect the head from impacts, debris, etc. during activities including but not limited to vehicle operation. Generally, helmets comprise a shell made of a suitably durable material with a cavity therein for the head.
- It will be appreciated that a helmet that completely encloses the head provides the greatest possible protection. Thus, it is common to equip helmets with a transparent shield to cover the eyes, to protect them while still permitting clear vision. Likewise, it is common for helmets to cover the nose and mouth and chin area completely.
- However, this configuration has a number of problems. For example, air exhaled by the wearer of the helmet is warm and humid. In a conventional fully enclosed helmet, moisture from the exhaled air has no place to escape, and thus tends to collect on the inner surfaces of the helmet. This is of special concern with respect to the shield, since even a relatively small amount of moisture condensation or “fogging” on the inner surface of the shield can obscure the wearer's vision significantly. This is a disadvantage in particular for helmets meant to be worn in cold environments, as fogging becomes more severe when the shield is chilled. In addition, the air inside the helmet rapidly becomes hot, humid, and stuffy, making the helmet uncomfortable to wear.
- Two methods conventionally are used to overcome these limitations. First, helmets have been equipped with air vents in order to permit the exchange of air with the outside. However, the airflow has proven to be less than satisfactory, and fogging of the shield remains a common problem. In addition, airflow generally has been inadequate to cool the helmet to the point where it may be worn comfortably for extended periods.
- Second, it is known to eliminate the shield, leaving the area around the eyes open and unprotected. This certainly eliminates the fogging problem, but requires the wearing of a separate piece of eye protection such as a pair of goggles. It will be appreciated that this is a considerable inconvenience. Furthermore, even with goggles, such a helmet leaves a significant portion of the wearer's face exposed. In high winds or cold temperatures, this can be uncomfortable. Indeed, in sufficiently hostile conditions, as those experienced by persons operating snowmobiles, there is a risk of injury due to excessive cold.
- In addition to these difficulties, in a conventional fully enclosed helmet that incorporates a shield, it is not possible to include a visor. Shields are conventionally designed to be raised from a closed to an open position so as to permit conversation, adjustment of goggles, etc. If a visor is included with a conventional helmet, however, it blocks the movement of the shield to the open position. For this reason, known helmets may include either a shield or a visor, but not both.
- Therefore it is the purpose of the present invention to overcome the deficiencies of the existing designs. It is the purpose of the present invention to provide a helmet that protects substantially the entire head while having sufficient ventilation both to control fogging of the shield and to provide sufficient air for respiration. It is a further purpose of the present invention to provide a helmet with sufficient ventilation to allow it to be worn comfortably for extended periods.
- An embodiment of a helmet in accordance with the principles of the present invention comprises a shell that defines a cavity therein. The shell is adapted to enclose the head of a person wearing the helmet. The helmet includes a transparent shield engaged with the shell, the shield being moveable between open and closed positions.
- The shell has at least one first air inlet and at least one first air outlet. The shell and the inner surface of the shield cooperate to define a first airflow path from the first air inlet, across the inner surface of the shield, and through the first air outlet. Thus, the inner surface of the shield is constantly in the path of air outside air moving through the helmet via the first airflow path. The outside air draws off moisture from the vicinity of the shield, minimizing moisture condensation or “fog” on the shield.
- The shell also has at least one second air inlet and at least one second air outlet. The shell defines a second airflow path from the second air inlet to the second air outlet. The cavity of the helmet is in communication with the second airflow path via the second air inlet, so that exhaled air is carried away and does not accumulate within the helmet.
- Another embodiment of a helmet in accordance with the principles of the present invention further comprises a separator. The separator is adapted to separate the first airflow path from the cavity.
- Still another embodiment of a helmet in accordance with the principles of the present invention further comprises a visor engaged with the shield and moveable therewith.
- Like reference numbers generally indicate corresponding elements in the figures.

helmet 10. As illustrated, thehelmet 10 comprises ashell 20. Theshell 20 defines acavity 22 therein. Theshell 20 is adapted to substantially enclose the head of a person wearing thehelmet 10, when the wearer's head is placed within thecavity 22. Theshell 20 may comprise any suitably durable material, including but not limited to metal, solid or foamed plastic, and fiberglass. Theshell 20 may comprise multiple layers of material, such as a rigid outer layer and a padded inner layer. Theshell 20 may be formed as a single piece, or may comprise a plurality of pieces secured together.

shield 40 is moveable between an open position, wherein airflow into thehelmet 10 past theshield 40 is enabled, and a closed position, wherein airflow into thehelmet 10 past theshield 40 is not enabled. Advantageously, the shield comprises a lockingmember 46 adapted to lock the shield in at least the upper or the lower position. Locking mechanisms are well known, and are not further detailed herein. As illustrated, the lockingmember 46 is located on a pivot joint between theshield 40 and theshell 20. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that other locations or configurations of locking means 46, or none at all, may be equally suitable. - The
shield 40 further comprises avisor 44 connected thereto, and moveable therewith. Advantageously, thevisor 44 may be removably connected to theshield 40, e.g. with a screw connection. Such means for removable connection are well known, and are not further detailed herein. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that it may be equally suitable for thevisor 44 to be fixed immovably to theshield 40, or to be integral with it. - The
shell 20 comprises at least onefirst air inlet 50 and at least onefirst air outlet 52. Theshell 20 cooperates with theinner surface 42 of theshield 40 to define afirst airflow path 54 through thehelmet 10. Thefirst airflow path 54 is configured such that air enters through thefirst air inlet 50, flows through thefirst airflow path 54 along theinner surface 42 of theshield 40, and then exits through thefirst air outlet 52. In this configuration, air from outside the helmet carries away moisture that has collected or might collect on theinner surface 42 of theshield 40. - As illustrated the
helmet 10 comprises twofirst air inlets 50 disposed proximate the bottom 30 and thefront 24 of thehelmet 10. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that different numbers, locations, and shapes offirst air inlets 50 may be equally suitable. - Similarly, as illustrated the

shell 20 further comprises at least onesecond air inlet 60 and at least onesecond air outlet 62. Theshell 20 defines asecond airflow path 64 that extends through thehelmet 10 from thesecond air inlet 60 to thesecond air outlet 62. Thesecond airflow path 64 is in communication with thecavity 22 via thesecond air inlet 60, so that air flows therebetween. Thesecond air inlet 60 connects thecavity 22 to thesecond airflow path 64, but does not connect either thecavity 22 or thesecond airflow path 64 to the outside of thehelmet 10. Thesecond airflow path 64 is configured such that exhaled air from theair cavity 22 enters thesecond airflow path 64 through thesecond air inlet 60, flows through thesecond airflow path 64, and then exits through thesecond air outlet 62. - As illustrated the
helmet 10 comprises sixsecond air inlets 60 disposed proximate the bottom 30 and thefront 24 of thehelmet 10. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that different numbers, locations, and shapes ofsecond air inlets 60 may be equally suitable. - Similarly, as illustrated the
helmet 10 comprises twosecond air outlets 62 disposed proximate the bottom 30 and the back 26 of thehelmet 10. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that different numbers, locations, and shapes ofsecond air outlets 62 may be equally suitable. - The first and second airflow paths may be configured in various manners. In particular, the first and second airflow paths may be defined wholly within a rigid outer layer of the shell. The first and second airflow paths may also be defined wholly within a padded inner layer of the shell. However, it will be apparent to those knowledgeable in the art that these configurations are exemplary only, and that the first and second airflow paths may be defined within some other layer, or within a combination of layers.
- Advantageously, the
helmet 10 comprises aseparator 70 adapted to cooperate with a wearer's head so as to separate thefirst airflow path 54 from thecavity 22. Theseparator 70 thus acts to reduce the flow of moisture from within thecavity 22 to theinner surface 42 of theshield 40. Theseparator 70 is engaged with at least one of theshell 20 and theshield 40. As illustrated, the separator comprises a gasket engaged with theshell 20, and adapted to seal to the wearer's face around the eyes. This is advantageous, in that it separates the wearer's respiratory orifices (nose and mouth) from thefirst airflow path 54, thereby restricting the flow of exhaled moisture to theinner surface 42 of theshield 40. However, it will be apparent to those knowledgeable in the art that this is exemplary only, and that a wide variety of configurations ofseparator 70, including but not limited to configurations that separate thefirst airflow path 54 from the wearer's respiratory orifices, may be equally suitable. - The
separator 70 may comprise any suitable material, including but not limited to cloth, rubber, and flexible or rigid plastic foam.

shell 20 comprises at least onefourth air inlet 80 that is in communication with thesecond airflow path 64. In this way, air may enter through thefourth air inlet 80 and create an increased draft in thesecond airflow path 64 towards thesecond air outlet 62, so as to carry away exhaled air efficiently. Additionally, thefourth air inlet 80 may provide a convenient source of fresh air for the wearer. Advantageously, thefourth air inlet 80 is positioned such that air enters thesecond airflow path 64 through thefourth air inlet 80 at a point that is closer to thesecond air outlet 62 than thesecond air inlet 60 is. That is, thefourth air inlet 80 is “downstream” from thesecond air inlet 60. Given such a configuration, air entering through thefourth air inlet 80 may produce a draft within thesecond airflow path 64 towards thesecond air outlet 62 without causing a draft of outside air to blow directly across the face of a person wearing thehelmet 10. This is particularly advantageous in cold weather, when drafts of cold outside air may prove especially uncomfortable. However, it will be apparent to those knowledgeable in the art that this configuration is exemplary only, and that different configurations offourth air inlets 80 with respect to thesecond air inlets 60 may be equally suitable. - As illustrated the
