Abstract
A helmet having a first helmet portion and a second helmet portion disposed adjacent to said first helmet portion, with the portions being slidably connected to one another and slidable relative to each other. The second helmet portion has a restraint defining a passage. The first helmet portion has an opening exposing a portion of the restraint. A securing member is received in the opening of the first helmet portion and slidable between engaged and disengaged positions. A portion of the securing member extends through the opening toward the second helmet portion and is received in the passage when in the disengaged position. The securing member engages the restraint and prevents relative movement of the first and second helmet portions when in the engaged position.
