Abstract: A breathing mask with a half mask and a nape band is to be improved such that secure contact of the mask in the entire nose and mouth region of the mask user is ensured by the nape band. The mask is thus effectively prevented from slipping despite the fact that the band is located in the nape region only. An additional application of a hood is possible without providing additional holding members. To accomplish this task, the band can be applied in the form of a rubber-elastic cuff (5) which has a neck opening (6) and a head opening (7). The mask and cuff are preferably made in one piece of silicone rubber, and the hood can additionally be bonded to the cuff.

These extensions each include a manually releasable connecting member which engages the slot, allowing the visor attachment to be easily removed from the helmet.

Abstract: A firefighter's hood which covers the upper portion of a firefighter. The hood normally has a shoulder section and a neck section and a head section, to cover those portions of the firefighter. The head section covers the head of the firefighter and has an opening to expose the face of the firefighter. The major part of the head section is made of thermal barrier material having given heat insulation qualities. However, the head section has an upper part which is adapted to be positioned at the upper portion of the head of the firefighter who wears the hood. The upper part of the head section of the hood has significantly less heat insulation qualities, so that heat can escape from the head of the firefighter and thus stress upon the firefighter which results from heat is reduced.

Abstract: The present disclosure is directed to a heat reflective shield having a plurality of spherical triangular panels each having aluminum foil on one side and a heat resistant fabric adhered to the other side, for use with a hard hat.

Abstract: A protective material for use in articles of apparel such as golves, leggings, sleeves, aprons and the like. The protective material comprises a base layer composed of textile material, an intermediate layer composed of a cut-resistant material having intermeshing strands defining pores therebetween and an outer layer composed of solid, elastomeric material which retards penetration by liquid. The elastomeric material covers and is bonded to the base layer which prevents passage entirely therethrough by liquid, elastomeric material but permits partial penetration. The solid, elastomeric material extends through the pores of the intermediate layer and encapsulates the strands thereof. A method for producing the protective material comprises dipping an article composed of base layer and intermediate layer into a bath of liquid, elastomeric material preferably after absorbing into the base layer a coagulant for the liquid elastomeric material.
