ADJUSTABLE HELMET SHELL
First Claim
1. A helmet comprising:
- a first helmet portion;
a second helmet portion disposed adjacent to said first helmet portion, said portions being slidably connected to one another and slidable relative to each other along a first axis so as to define an internal cavity of varying volume;
a securing member mounted to a location on said first helmet portion, said securing member being slidable between an open and a closed positions, said securing member being slidable along a second axis in a plane substantially parallel to the plane of said location, said first and second axes being non-parallel; and
said second helmet portion having a restraint complimentary to said securing member, wherein said securing member and said restraint cooperate to inhibit movement of said first helmet portion relative to said second helmet portion when said securing member is in said closed position.

Abstract
A hockey helmet (20) comprising a front helmet portion (22) and a rear helmet portion (24) disposed to be moveable relative to each other so as to define an internal cavity of varying volume, a securing member (26) being mounted to a location on the front helmet portion (22) adjacent the temple thereof, the securing member (26) being slidable between a first or open position and a second or closed position, the rear helmet portion (24) having a restraint (28) configured and disposed to be complimentary to the securing member (26) such that when the securing member (26) cooperatively engages the restraint (28), the relative displacement of the front helmet portion (22) and the rear helmet portion (24) is inhibited. The restraint (28) comprises a number of positions in which the securing member (26) can be cooperatively engaged such that the volume of the helmet (20) may be modified.
