Carrier for a Helmet

Abstract

A carrier for a helmet includes a sack having a main opening at an upper end thereof. The main opening has an approximately horizontal orientation and defines a vertical axis. The sack defines an interior volume. A partition is disposed in the interior volume of the sack so as to define distinct upper and lower compartments in the interior volume. The sack includes a re-closable opening to the lower compartment. The lower compartment is configured to receive the helmet in a position wherein a portion of the partition protrudes into a cavity of the helmet and the helmet becomes a structural part of the carrier. The upper compartment includes a portion thereof that is nested in the cavity. The sack has a perimeter of one meter or less in a plane, lying perpendicular to the vertical axis that intersects with the re-closable opening.

What is claimed is: 
     
         1 . A carrier for a helmet, the carrier comprising:
 a sack having a main opening at an upper end thereof, the main opening having an approximately horizontal orientation and defining a vertical axis, the sack defining an interior volume;   a partition disposed in the interior volume of the sack so as to define distinct upper and lower compartments in the interior volume;   wherein (i) the sack includes a re-closable opening to the lower compartment, (ii) the lower compartment is configured to receive the helmet in a position wherein a portion of the partition protrudes into a cavity of the helmet and the helmet becomes a structural part of the carrier, (iii) the upper compartment includes a portion thereof that is nested in the cavity, and (iv) the sack has a perimeter of one meter or less in a plane perpendicular, lying perpendicular to the vertical axis, that intersects with the re-closable opening.   
     
     
         2 . The carrier of  claim 1 , wherein the lower compartment is configured to receive and store the helmet in an inverted position, so that the portion of the upper compartment nested in the cavity is directly below the main opening. 
     
     
         3 . The carrier of  claim 1 , wherein the re-closable opening occupies a distance around the foregoing perimeter that is at least half of the length of the perimeter. 
     
     
         4 . The carrier of  claim 1 , wherein the partition is sized so that, when the lower compartment is not used, the partition conforms to the carrier so as to collapse the lower compartment, to render the entire interior volume of the carrier accessible from the main opening.
