Abstract
Abstract A rigid shell helmet has an improved way of holding the shell uniformly over the head of the wearer. This includes a cap formed of a network of non-stretchable bands arranged in arcs passing closely over the head and crossing each other at many points to form the legs of triangles arranged in hexagonal groups over the head with the bands in tension between the apexes of the triangles. The cap provides a firm grip on the head at all angles, and is centered within the helmet shell by a plurality of non-stretchable straps extending tangentially in tension from the cap to the shell. Several of these straps are preferably in the zenith region of the cap, and the lower region of the cap is secured to the lower region of the shell.

Claim 1
Independent Claim
162 words
In a helmet having a protective outer shell, improved means for maintaining said shell in a substantially uniformly spaced relation over the head of the wearer, said means comprising: a. a cap formed of a network of substantially non-stretchable, flexible bands arranged in arcs passing closely over said head; b. said bands crossing each other at a plurality of points to form the legs of triangles arranged in hexagonal groups over said head; c. said bands being fixed relative to each other at said crossing points at the apexes of said triangles; d. said bands being in tension between said apexes of said triangles when said cap is on said head; e. a plurality of substantially non-stretchable straps secured to said cap and extending substantially tangentially in tension from said cap to said Shell to support said cap in spaced relation to said shell; and f. means for securing the lower region of said cap to the lower region of said shell.
