Screen bar for respirator mountable to helmet via plug and socket arrangement so that bar and typically visor can be raised whilst helmet is worn

摘要

A screen bar for a respirator or helmet adapted to carry a protective screen has adjacent each end of the bar, a pivot, an arm extending from the pivot, and a rod attached to the arm at a point spaced from the pivot so that a free end of the rod extends back towards the pivot, with the free end having half of a plug and socket arrangement. The bar can thus be mounted on the helmet to dispose the screen in front of the wearer's face and the screen can be raised whilst the helmet is being worn.
