Abstract
An adjustable head band suspension system for use in a safety hat shell is disclosed. The suspension system includes a head encircling head strap having overlapping rear end portions and an arc shaped channel adapted to fit the back of a wearer's head. The overlapping end portions of the head strap are slidably disposed in the channel. A suitable adjusting device, such as a rack and pinion or buckle is attached to the channel to adjust the amount of overlap of the end portions. The channel is attached by means of a pair of tabs to a rear interior surface portion of the shell and a front end portion of the head strap is connected to a forward interior surface portion of the shell. A manually compressible, resilient buckle assembly is disclosed which can be used by itself for adjusting and maintaining the desired length of overlap of the overlapping end portions of a head strap or which can be used in association with the arc shaped channel as a central portion thereof.
