The present disclosure generally relates to helmets. In particular, the disclosure relates to interactive helmets responsive to impacts against surfaces.
During contact sports and other physical activities, helmets have long been worn to protect users from sustaining injuries to the head and brain. Over time, helmets have become lighter and have provided additional cushioning to help better protect users. However, lighter helmets offer less protection for a user's head and brain, and additional cushioning can be ineffective. Being injured while wearing conventional helmets can result in serious injuries including sustaining a concussion and chronic traumatic encephalopathy (CTE) brain damage. As athletes experience long and short-term brain injuries resulting from head impacts, there is a need for more effective helmets. Short-term brain injuries typically result from hard falls, impact with objects, and helmet-to-helmet contact. While there are protocols in place to protect players from concussions, repeatedly experiencing concussions can result in brain damage which can be detected by medical resonance imaging (MRIs) and autopsies of athletes who have sustained multiple concussions. Consequently, traditional helmets have many shortcomings and do not fully protect users.
Embodiments of the present disclosure may provide an interactive helmet system for reducing brain injuries. The system may include at least one inflatable air pouch that may be provided in an interior of a helmet in an active position. An air pouch pressure may increase over a predetermined inflation time, and the at least one inflatable air pouch may not depressurize in the active position. The system may include a force measuring instrument that may be provided in the interior of the helmet to predetermine an impact force of the helmet against a surface. The air pouch pressure may increase in proportion to the force. The system may further include an inflation device that may be provided in the interior of the helmet to initiate inflating the at least one inflatable air pouch. The system may include a pressure sensor that may be provided in the interior of the helmet to monitor the air pouch pressure of the at least one inflatable air pouch. A pressure regulator may control and maintain the air pouch pressure at or above a predetermined pressure. The air pouch pressure may increase to a maximum of approximately twice the predetermined pressure. The predetermined inflation time may be from approximately 0.01 to 0.5 seconds following an impact of the helmet against the surface. The inflation device may provide a signal to at least one valve that may control a flow of gas into the at least one inflatable air pouch. The system may include additional inflatable air pouches that may be provided in the interior of the helmet in the active position. The force measuring instrument may be a force gauge and/or a rupture disc. The inflation device may be actuated mechanically without utilizing electronics upon undergoing the predetermined impact force.
The system may include a strap that may be provided to support at least one of a user's chin and jaw. The strap may include the at least one inflatable air pouch that may be arranged to prevent injuries. An internal helmet cushioning material may be provided to harden or soften as an electrical current may be applied to the interactive helmet system. An internal helmet cushioning material may be provided to harden as an impact may increase. The impact may result from physical forces that may be applied to the interactive helmet system.
