  • Helmet assembly may refer to a helmet, a visor, and/or eyewear associated with the helmet, either separately or in any combination.
  • the systems and techniques described herein may allow for a helmet to receive and hold an eyewear (e.g., sunglasses) of the wearer.
  • the helmet can include features to hold the eyewear such that, for example, when weather conditions change, the wearer has a convenient and secure place to hold the eyewear instead of hooking the eyewear on the wearer's clothing or placing it in another unsecure area.
  • the helmet described herein may include a visor with air deflector vents to deflect airflow around the helmet for lower drag and/or deflect airflow to portions of the helmet to aid in the cooling of the wearer.
  • the helmet may include an outer shell that includes one or more channels configured to receive and hold at least a portion of a corresponding eyewear.
  • the helmet can include the visor.
  • the visor can be coupled to the outer shell of the helmet and can include a vent disposed on a lower portion of the visor configured to direct airflow to a portion of the outer shell and/or the wearer's head.
  • FIG. 1 shows a perspective view of a helmet, in accordance with an embodiment of the invention.
  • FIG. 1 shows helmet 100 with an outer shell 102 and a visor 104 .
  • the outer shell 102 may be configured to be disposed around the head of a wearer.
  • one or more liners may be disposed within the outer shell 102 .
  • the liners may be, for example, padding to absorb and dissipate impacts against the outer shell 102 to protect the wearer's head.
  • the outer shell 102 may include channels 106 and openings 108 .
  • Channels 106 may be coupled to or formed within the outer shell 102 .
  • the channels 106 may be configured to receive a portion of a corresponding eyewear.
  • the channels 106 may receive the arms (e.g., temples) of a corresponding glasses or sunglasses.
  • the channels 106 may be configured to hold the eyewear such that one or more lenses of the eyewear is disposed on a rearward portion of the outer shell (e.g., when the channels 106 hold the eyewear, the eyewear may be facing rearward).
  • Such a configuration may dispose the eyewear away from the eyes of the wearer and can also dispose the eyewear to prevent or minimize disruption of airflow over the helmet 100 .
  • Visor 104 may be coupled to or integrated within the outer shell 102 (e.g., formed as a part of the outer shell 102 ).
  • the visor 104 may provide shade to prevent sunlight from shining into the wearer's eyes.
  • the visor 104 may include one or more vents configured to redirect air.
  • the visor 104 may, for example, be configured to redirect air into one or more openings 108 (e.g., to cool the wearer) or configured to redirect air around the outer shell 102 (e.g., to decrease air resistance).
  • FIG. 2 shows a rear view of the helmet of FIG. 1 , in accordance with an embodiment of the invention.
  • the outer shell 102 may include a plurality of channels 106 A and 106 B. Each of the channels 106 A and 106 B can be configured to each receive an arm of the eyewear.
  • the channel 106 A may be, for example, disposed on one lateral side of the outer shell and the channel 106 B may be disposed on an opposite lateral side of the outer shell 102 .
  • the channel 106 A may thus be configured to receive a first arm of the eyewear and the channel 106 B may be configured to receive a second arm of the eyewear.
  • one or both of the channels 106 A and 106 B may be curved to hold the corresponding first arm and/or the second arm within the first channel and/or the second channel.
  • a curvature may correspond to a curvature of the arm(s).
  • the curvature may be a substantially convex shape. The convex shape may aid in holding the eyewear to the outer shell 102 by, for example, preventing the arms of the eyewear, when inserted into the channels 106 A and/or 106 B, from decoupling from the channels 106 A and/or 106 B unless pushed outward (e.g., the arms are pushed away from each other) or otherwise deformed.
  • FIG. 3 shows a cross-sectional view of the helmet of FIG. 1 along line 3 - 3 ′ in FIG. 2 , in accordance with an embodiment of the invention.
  • Channel 106 A may include a first portion 112 A, a second portion 114 A, and a third portion 116 A.
  • Channel 106 B may accordingly include a first portion 112 B, a second portion 114 B, and a third portion 116 B.
  • a portion of the corresponding eyewear, such as the arms of the eyewear may be inserted into the channels 106 A and 106 B through first portions 112 A and 112 B, respectively, before traveling to second portions 114 A and 114 B.
  • the ends of the arms may then be disposed in the third portions 116 A and 116 B when the arms are held within the channels 106 A and 106 B, respectively.
  • the first portions 112 A and 112 B may include a lead-in that, when the surfaces of the first portions 112 A and 112 B are extended in an imaginary line towards the back of the outer shell 102 , form an angle.
  • force from contact between the arms and the first portions 112 A and 112 B may provide force to displace the arms apart.
  • the arms may thus, accordingly, provide a reaction force to grip portions of the channels 106 A and 106 B, respectively, to hold the arms to and/or within the channels 106 A and 106 B.
  • the second portions 114 A and 114 B may be disposed more parallel to each other than first portions 112 A and 112 B.
  • the second portions 114 A and 114 B may form surfaces that allow for the arms of the eyewear to more easily slide within the channels 106 A and 106 B.
  • the third portions 116 A and 116 B may be angled in the opposite direction of the first portions 112 A and 112 B. Thus, the surfaces of the third portions 116 A and 116 B may be extended in an imaginary line towards the front of the outer shell 102 to form an angle.
  • the third portions 116 A and 116 B may be shaped so that, if a wearer wishes to remove the arms of the eyewear from the channels 106 A and 106 B, the arms may need to be displaced apart to remove them from, at least, the third portions 116 A and 116 B. As such, without the arms of the eyewear being displaced (e.g., by a force provided by the wearer), the arms of the eyewear may be held within the channels 106 A and 106 B.
  • the first portion 112 A, the second portion 114 A, and the third portion 116 A and/or the first portion 112 B, the second portion 114 B, and the third portion 116 B may form a C-shaped path for the arm(s) of the eyewear to travel along.
  • Such a C-shaped path may allow for the arms to be easily inserted into the channels 106 A and 106 B and securely held within the channels 106 A and 106 B when portions of the arms (e.g., the end of the arms) are disposed within the third portions 116 A and 116 B.
  • the channels 106 A and 106 B and/or the arms of the eyewear may include features to provide haptic feedback to the wearer that the arms are fully inserted into the channels 106 A and 106 B.
  • the arms can be configured to bottom against the walls of the channels 106 A and/or 106 B.
  • the C-shaped path may decrease the insertion force required for the arms to be inserted into the channels 106 A and/or 106 B near the end of travel of the channels 106 A and/or 106 B.
  • the C-shaped path may position the arms within the channels 106 A and/or 106 B near the end of travel, effectively automatically moving the arms into the proper position.
