First Claim
1. A helmet comprising:
- a first helmet portion having two opposed first lateral portions;
a second helmet portion having two opposed second lateral portions, the helmet portions being connected to be relatively slidable along a sliding direction with each of the first lateral portions overlapping and extending outwardly of a respective one of the second lateral portions;
each second lateral portion having a restraint defining at least a passage extending along the sliding direction and a plurality of parallel restraint fingers adjacent to the passage;
each first lateral portion having an opening defined therein and exposing the passage and restraint fingers in at least two different relative positions of the slidably connected helmet portions; and
a securing member connected to each first lateral portion and slidable along a path having opposed ends with one of the ends defining an engaged position where the securing member prevents relative motion between the helmet portions and the other of the ends defining a disengaged positions where the helmet portions are relatively slidable, wherein in the disengaged position a complementary portion of the securing member is extending through the opening toward the second lateral portion and is received in the passage with the complementary portion only occupying part of a length of the passage as defined along the sliding direction, and wherein in the engaged position the complementary portion engages the restraint fingers.

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.
