Abstract
An adjustable helmet liner for a protective helmet is disclosed. The adjustable helmet liner comprises at least one liner wall having a peripheral surface adapted to substantially conform to, and fit within, the protective helmet for engagement with the head of a wearer of the protective helmet. The at least one liner wall includes an outer surface and an inner surface. The outer surface is adapted to be disposed adjacent the interior surface of the helmet and the inner surface is adapted to be spaced from the interior surface of the helmet whereby the liner may be inserted into the protective helmet and adjusts to the head of the wearer of the protective helmet. The adjustable helmet liner further includes at least one expandable band disposed along a portion of the outer surface of the liner wall, whereby the at least one expandable band provides for the adjustment of the liner to the head of the wearer of the protective helmet. A protective helmet having an adjustable helmet liner is also disclosed.
