Elbow clip apparatus and system

Abstract

An apparatus for attenuating the transmission of an impact force from a faceguard to a helmet shell includes: at least one lobe configured to constrain at least a portion of the faceguard; a fastener attachment disk extending through recesses in the helmet shell; and a force attenuation protrusion coaxially aligned with the fastener attachment feature

What is claimed is: 
     
         1 . An apparatus for attenuating the transmission of an impact force from a faceguard to a helmet shell, the apparatus comprising:
 a one or more lobe, at least partially cylindrical with a lobe central axis, configured to coaxially constrain at least a portion of the faceguard;   a substantially planar area disposed adjacent to the one or more lobe having a front surface and a back surface;   a fastener attachment feature that is substantially cylindrical, having a fastener attachment feature central axis, disposed perpendicular to the substantially planar area and extending through the front surface and back surface; and   a force attenuation protrusion that is substantially cylindrical, having a force attenuation protrusion central axis, with a first face disposed coplanar to said back surface, a second face disposed parallel to the first face, and having a thickness between the first face and the second face, wherein the force attenuation protrusion is coaxially aligned with the fastener attachment feature.   
     
     
         2 . The apparatus of  claim 1  where the force attenuation protrusion is made from a first material having a first durometer and the one or more lobe and the substantially planar area are made from a second material having a second durometer. 
     
     
         3 . The apparatus of  claim 2  where the first durometer is less than the second durometer.
