Abstract
An expolosively-activated mechanism for releasing a breathing mask from a protective helmet to permit the user to breathe the ambient atmosphere independently of the mask utilizes coacting mechanisms in the form of a bayonet and a bayonet receiver and an explosive charge mounted in the bayonet receiver for explosively separating the bayonet receiver and permitting the bayonet to drop from the helmet upon the occurrence of a predetermined event. The bayonet receiver includes components defining a bayonet-receiving channel which is held in assembled relationship by a plurality of shanked fasteners and a cutting blade interposed between the explosive charge and the shanked fasteners. The cutting blade is adapted to receive the explosive force generated by the explosive charge and sever every shanked fastener of the bayonet receiver upon receipt of the explosive force. The component-holding capacity of the fasteners are thereby destroyed, and the receiver components are permitted to separate from one another and the bayonet is permitted to drop from the receiver. The explosive force of the charge is substantially confined within the bayonet receiver.
