Helmet for reducing concussive forces during collision and facilitating rapid facemask removal
View Patent ↗An improved design for a helmet to reduce injuries caused by helmet-to-helmet collisions. Certain embodiments include novel quick release features that permit the detachment of a facemask from a helmet in 30 seconds or less so as to attend to an injured player in a rapid fashion. Other aspects relate to impact energy absorbing constructions employing an inner layer, an outer layer spaced apart from the inner padding layer, at least one layer that includes an array of polygonal structures, and at least one layer having a shock-absorbing elastomer, a visco-elastic polymer, an impact dispersing gel, or shape memory material. Still other embodiments include a wireless device with a sensor module coupled to the football helmet generating sensor data in response to an impact to the football helmet.

A helmet comprising, a facemask having a facemask bar portion connected to the helmet by at least two quick release facemask connecting structures positioned on at least a left side and a right side of the helmet, wherein said at least two quick release facemask connecting structures include a coupler mechanism receiving said facemask bar portion to secure the facemask bar portion to the helmet, said coupler mechanism having a contoured exterior with a metal post movably retained in an interior of said coupler mechanism by a magnetically actionable locking assembly including a retaining part, said magnetically actionable locking assembly adapted to move from a first locked position to a second unlocked position when a magnetic force is applied to the contoured exterior in a manner that causes the metal post to move from a retained position to a non-retained position, wherein the non-retained position allows for detachment of the facemask bar portion from the helmet.
2. The helmet of claim 1 , wherein said magnetically actionable locking assembly is adapted to move from said first locked position to said second unlocked position when the retaining part is attracted to the magnetic force, by employing magnets selected from the group consisting of a NdFeB magnet, a hard ferrite magnet, a SmCo magnet, and an AlNiCo magnet.

15. A helmet comprising an outer shell; an inner shell that is more rigid than the outer shell, said outer shell being more flexible than the inner shell; said helmet having at least one layer that includes an array of impact absorbing structures proximate to the outer shell and proximate to the inner shell, and at least one layer providing resistance to an impact force, said at least one layer comprising one or more of the following materials: thermoplastic polyurethane, an impact absorbing silicone, an energy-absorbing foam, a polymer gel, a shock-absorbing elastomer, a visco-elastic polymer, an impact dispersing gel, and shape memory material, and a facemask having a facemask bar portion connected to the helmet by at least two quick release facemask connecting structures positioned on at least a left side and a right side of the football helmet, said at least two quick release facemask connecting structures including a coupler mechanism adapted to receive said facemask bar portion to secure the facemask bar portion to the helmet, said coupler mechanism having a exterior with a metal post movably retained in an interior of said coupler mechanism by a magnetically actionable locking assembly including a retaining part, said magnetically actionable locking assembly adapted to move from a first locked position to a second unlocked position when a magnetic force is applied to the exterior in a manner that causes the metal post to move from a retained position to a non-retained position, wherein the non-retained position allows for detachment of the facemask bar portion from the helmet, and wherein the retaining part of the magnetically actionable locking assembly is adapted to be attracted to a magnetic force that pulls the retaining part from the first locked position to move the post;
wherein said at least one layer comprises a shock-absorbing elastomer adapted to withstand the shock of an impact force without permanent deformation; and
wherein the helmet comprises a wireless device comprising a sensor module, coupled to the helmet, said sensor module adapted to generate sensor data in response to an impact to the helmet.
