| Abstract: |
A quick-donning head harness assembly (10) used in combination with a respirator face mask assembly (12) of the type including a rigid facepiece (14) and a flexible face seal (16), which head harness assembly and face mask assembly may be quickly donned and adjusted without becoming entangled with the wearer's hair. The head harness assembly includes a cap (24) provided with a lower strap casing (24.2) and an upper strap casing (33). A lower elasticized strap passes through the lower casing, the forward ends of the strap passing through adjusting buckles (46) supported by lower corners of the facepiece. Rings (38) are connected to the upper corners of the facepiece (14) and an upper adjustable strap (48) has right and left temple portions (48.2) passing through the ring, the strap being folded back upon itself, the end portions (48.3) of the strap being provided with a "velcro" pile which may cooperate with a "velcro" pile on the upper strap casing (33) for adjustably positioning the upper corners of the facepiece. In addition, a rigid support (26) extends between the upper corners of the facepiece and the top forward corners of the cap (24).

What is claimed is:
1. The quick-donning head harness assembly used in combination with a face mask assembly intended for eye and respiratory protection, the face mask assembly having upper and lower side portions to which the head harness assembly is secured, the head harness assembly being capable of quickly suspending the face mask assembly in front and aligning it with the wearer's face, leaving hands free for quickly adjusting upper and lower seal tightness to provide a continuous seal between the perimeters of the face mask assembly and face whereby penetration of contaminants past the seal is minimized; and said head harness assembly comprising:
- a cap having a front portion, a top portion, a lower back portion and an intermediate portion, said cap being suitably contoured to fit portions of the back, top and sides of the wearer's head;
- nonadjustable constant length securing means for securing the upper side portions of the face mask assembly to the front portion of the cap for suspending the face mask assembly and enabling quick alignment of the face mask assembly in front of the wearer's face;
- lower manually adjustable length securing means for securing the lower back portion of the cap to the lower side portions of the face mask assembly for pulling the lower side portions of the face mask assembly inward and towards the face into sealing contact with at least the lower portion of the face; and
- upper manually adjustable length securing means for securing the intermediate portion of the cap to the upper side portions of the face mask assembly for pulling the upper side portions of the face mask assembly inward and towards the face into sealing contact with at least the upper portion of the face including the temples, the intermediate portion of the cap being located between the front portion and the lower back portion of the cap.
