Cord Lock Fit System for a Helmet

Abstract

A helmet with an adjustable fit system is disclosed herein. The helmet includes a protective shell and the adjustable fit system. The adjustable fit system is coupled to an positioned at least partially within the protective shell. The adjustable fit system includes a frame having two cord attachment points, a cord coupled to the two cord attachment points of the frame, and a tension device releasably coupled to the cord between the two attachment points. The tensioning device is configured to adjust a distance between the two attachment points of the frame via movement of the tensioning device relative to the cord to adjust a size of the adjustable fit system. The cord may pass through the tensioning device to form a first portion between each cord attachment point and the tensioning device, and a looped second portion extending from the tensioning device away from the first portion.

         3 . The helmet of  claim 2 , wherein cord comprising a single cord extending between the two attachment points and the second portion of the cord forms a loop extending from the tensioning device. 
     
     
         4 . The helmet of  claim 3 , wherein the frame further comprises a loop clip configured to receive the loop for removable coupling. 
     
     
         5 . The helmet of  claim 3 , wherein the tensioning device comprises a spring-loaded cord lock comprising a spring and a tab configured to releasably couple the cord within the tensioning device. 
     
     
         6 . The helmet of  claim 1 , wherein the frame comprises two opposing helmet attachment end points coupled to the helmet. 
     
     
         7 . The helmet of  claim 1 , wherein the frame comprises a central helmet attachment point coupled to the helmet. 
     
     
         8 . The helmet of  claim 1 , wherein the tensioning device is integrally formed to the frame of the adjustable fit system. 
     
     
         9 . An adjustable fit system for a protective helmet, comprising:
 a frame comprising two cord attachment points;   a cord fixedly coupled to the two cord attachment points of the frame; and   a tension device releasably coupled to the cord between the two attachment points, the tensioning device configured to adjust a distance between the two attachment points of the frame via movement of the tensioning device relative to the cord to adjust a size of the adjustable fit system.   
     
     
         10 . The adjustable fit system of  claim 9 , wherein the cord passes through the tensioning device to form a first portion of the cord between each cord attachment point of the frame and the tensioning device, and a second portion of the cord extending from the tensioning device away from the first portion of the cord. 
     
     
         11 . The adjustable fit system of  claim 10 , wherein cord comprising a single cord extending between the two attachment points and the second portion of the cord forms a loop extending from the tensioning device. 
     
     
         12 . The adjustable fit system of  claim 11 , wherein the frame further comprises a loop clip configured to receive the loop for removable coupling. 
     
     
         13 . The adjustable fit system of  claim 11 , wherein the tensioning device comprises a spring-loaded cord lock comprising a spring and a tab configured to releasably couple the cord within the tensioning device. 
     
     
         14 . The adjustable fit system of  claim 9 , wherein the frame comprises two opposing helmet attachment end points configured to couple to a helmet. 
     
     
         15 . The adjustable fit system of  claim 9 , wherein the frame comprises a central helmet attachment point configured to coupled to a helmet. 
     
     
         16 . The adjustable fit system of  claim 9 , wherein the tensioning device is integrally formed to the frame of the adjustable fit system. 
     
     
         17 . A method of securing a protective helmet to a head of a wearer, comprising:
 placing a helmet on a head of a wearer, the helmet comprising an adjustable fit system coupled to and positioned at least partially within a protective shell of the helmet, the adjustable fit system comprising a frame comprising two cord attachment points and coupled to the protective shell, a cord fixedly coupled to the two cord attachment points of the frame, and a tension device releasably coupled to the cord between the two attachment points; and   tensioning the cord to adjust a fit of the helmet by adjusting a distance between the two attachment points of the frame by moving the tensioning device relative to the cord.   
     
     
         18 . The method of  claim 17 , wherein tensioning the cord comprises tensioning a first portion of the cord extending between the attachment point and the tensioning device by pulling a second portion of the cord extending from the tensioning device away from the attachment point. 
     
     
         19 . The method of  claim 18 , wherein pulling a second portion of the cord comprises pulling a looped second portion extending from the tensioning device. 
     
     
         20 . The method of  claim 19 , further comprising removably coupling the looped second portion to a loop clip on the frame.
