Definitions

  • the present application relates generally to helmets, and more specifically to scalable helmets with attached accessories.
  • bump helmets lightweight non-ballistic "bump” helmets (rated only for blunt impact) and full ballistic helmets (rated to stop a variety of fragmentation and/or small arms fire).
  • Typical bump helmets weigh 1-2 pounds less than a ballistic rated helmet and provide increased ventilation, as vents compromise the ability of a ballistic shell to protect the wearer.
  • Examples of bump helmets include Team Wendy EXFIL® Carbon, Team Wendy EXFIL® LTP, OpsCore FAST Base Jump, OpsCore FAST Carbon, and Pro- Tec BRAVO.
  • Military users of such helmets may carry one of each type of helmet depending on the environment and the type of threats anticipated.
  • Mounting accessories to military helmets is also known to those skilled in the art.
  • Accessories are typically mounted on the front, sides, or back of the helmet.
  • Accessories mounted to the front of the helmet include, but are not limited to, vision devices such as night optical devices (NODs).
  • Front-mounted accessories are typically attached to the helmet with a standard rectangular interface known as a "shroud" that is fitted to the front of the helmet or helmet shell. This interface is commonly used by the US military and internationally, and vision systems made by various companies are designed to work with the same interface.
  • Accessories mounted to the sides or back of the helmet include, but are not limited to, communications headsets (commonly mounted to the sides of the helmet), lights (commonly mounted to the sides of the helmet), battery packs or counterweights
  • goggles are commonly mounted to the back of the helmet.
  • These accessories are typically attached via a "rail system” such as the Ops-Core ARC rail and ARC-ACH kit, MIL-STD-1913 rails (also known as Picatinny rails), or the Team Wendy EXFIL Rail 2.0.
  • a "rail system” such as the Ops-Core ARC rail and ARC-ACH kit, MIL-STD-1913 rails (also known as Picatinny rails), or the Team Wendy EXFIL Rail 2.0.
  • These rail systems are secured to the shell of the helmet, covering significant portions of the sides and rear of the helmet.
  • the user may purchase an additional accessory (e.g., one for each helmet), or may remove the accessory and transfer it between helmets each time they decide to change helmets.
  • An exemplary scalable helmet includes a base helmet having a lower edge, a ballistic portion removably attached to the base helmet, and a mounting portion including at least one connector.
  • the mounting portion extends along a portion of the lower edge of the base helmet for connecting an accessory to the scalable helmet.
  • the mounting portion extends below a lower edge of the ballistic portion when the ballistic portion is attached to the base helmet, and the ballistic portion is removable from the base helmet without removing an accessory connected to the connector.
  • Another exemplary scalable helmet includes a base helmet having a lower edge, a helmet shell, a mounting portion including at least one connector, and at least one accessory connected to the connector.
  • the mounting portion extends along a portion of the lower edge of the base helmet for connecting an accessory to the scalable helmet.

  • the mounting portion extends below a lower edge of the ballistic portion when the ballistic portion is attached to the base helmet, and the ballistic portion is removable from the base helmet without removing an accessory connected to the connector.
  • Still another exemplary embodiment of the present disclosure relates to a method for using a scalable helmet.
  • the method includes providing a scalable helmet including a base helmet having a lower edge and a mounting portion having at least one connector; attaching an accessory to the connector; and attaching a ballistic portion to the scalable helmet after attaching the accessory to the mounting portion.
  • the mounting portion extends along a portion of the lower edge of the base helmet for connecting an accessory to the scalable helmet.
  • the connector includes at least one restraining portion for restraining movement of the accessory attached to the base helmet.

  • ballistic refers to a helmet or helmet component that is designed to provide protection from ballistic threats.
  • Ballistic helmets and helmet components can be designed to provide protection from varying degrees of threats, including, but not limited to, fragmentation, handgun rounds, and rifle rounds.
  • Ballistic components designed to protect from a 7.62 x 39 or 7.62 x 54 rifle round are typically heavier and bulkier than those designed to protect from a 9 mm handgun round, which are still heavier than those designed to protect from fragmentation only (typically graded by the v50 level of a standard fragment, which itself can vary greatly).
  • “non-ballistic” refers to a helmet or helmet component that is not designed to provide protection from ballistic threats or to meet ballistic protection ratings. Non-ballistic helmets and helmet components may still provide some protection from a ballistic threat, but are not designed and/or rated for such threats.
  • scaling of a scalable helmet refers to adding or subtracting ballistic protection from a base helmet platform.
  • Scaling "up” a scalable helmet refers to adding ballistic protection to protect from varying degrees of ballistic threats.
  • a fully scaled up helmet is fully or heavily armored, thereby protecting the wearer from high ballistic threats.
  • Scaling "down” a scalable helmet refers to removing ballistic protection to reduce weight and increase ventilation.
  • Applicant has appreciated the need for a single helmet that can be configured by the wearer to provide variable levels of protection and comfort while maintaining functionality of helmet mounted accessories.
  • the present disclosure is directed to a scalable helmet that allows the wearer to add or remove ballistic protection to tailor the helmet to the risk profile of a particular mission without removing accessories or changing the fit and padding of the helmet.
  • the wearer can be equipped with the lightest weight helmet available that meets the desired threat protection level, while maintaining functionality of helmet mounted accessories.
  • the user can scale down the helmet during low risk phases of a mission, such as transit, to reduce the weight of the helmet and improve ventilation, thereby reducing fatigue of the wearer while maintaining full blunt impact protection and the ability to utilize helmet mounted devices. The user can then scale up the helmet by quickly reattaching the ballistic portion in anticipation of entering a phase of the mission with increased risk.
  • the user may carry multiple ballistic shells rated to different threat levels that can be interchanged depending on needs of the particular mission phase. Furthermore, if a ballistic shell becomes damaged, a new or borrowed shell can be installed without needing to adjust the fit of the helmet or change the accessories.

  • the base helmet 101 may be constructed of any suitable material, such as, for example, carbon fiber, a polymer such as ABS or polycarbonate, or the like. In some embodiments, the base helmet 101 includes additional layers to catch ballistic fragments, for example, a spall liner.
  • Ventilation openings are provided in helmets to allow air to flow through the helmet as it is worn on the wearer's head, facilitating cooling as the wearer perspires. Existing ventilation openings are limited in size, however, to provide sufficient impact protection against impacts directly onto a vent. The ventilation openings 102 of the present disclosure are significantly larger than those of prior art helmets while still providing sufficient impact

This overlap provides protection against ballistic projectiles impacting the helmet 100 along the interface between the shroud mount 110 and ballistic portion 140.
  • the ballistic portion 140 may overlap the shroud mount 110 without a chamfered edge 143 to provide additional protection in the area surrounding the shroud mount 110.

For example, an individual ballistic portion 140 may cover only the front half, less than half, or only a small portion of the base helmet 101. In some embodiments, the multiple ballistic sections provide different levels of ballistic protection for different portions of the helmet 100, such as providing increased ballistic protection for the front half of the helmet where a soldier is more likely to be attacked.
