Abstract

A device for one hand donning of a head harness suspending an oxygen breathing mask wherein lateral supports are arcuate in shape to extend well over the ears of the user, even though the user may be wearing earphones, and wherein there is a transverse support or neck piece attached to the rear ends of the lateral support by hinges, the pivot axes of which are disposed at such an angle that the lateral supports can fold toward each other in a flat package and which when opened will assume positions adapted to readily fit over the head. The suspension is adjustable to size by a crown strap attached to midportions of the lateral supports and a rear strap which extends from the crown strap to a point of attachment with the transverse support. The front ends of the lateral support are pivotally connected to the mask so that when collapsed the mask will assume a tilted position improving the compactness of the package but capable of tilting to a proper operating position when the mask is donned.

Claims

1. A quick donning mask and foldable suspension for mounting said mask on the head of user comprising right and left lateral supports having each a substantially arcuate shape wherein an arcuate midportion is adapted to extend above the ears of the user and respective front and rear ends are adapted to extend respectively forward and rearward of the ears, said lateral supports being continuous and substantially rigid throughout the length between front and rear ends, a separate rearwardly located substantially rigid transverse support adapted to extend across the upper parts of the user'"'"''"'"'s neck, respective lateral ends of said transverse support having a hinged attachment to respective rear ends of said lateral supports, the axis of movement of said hinged attachment being in the plane of said lateral supports and when worn being substantially parallel to the adjacent surface of the user'"'"''"'"'s head, a transverse crown strap having ends connected to respective lateral supports, lateral extensions on respective right and left sides of said mask and a pivotal connection between an outer end of each said extensions and the font end of the respective lateral support, said lateral supports when removed from the user'"'"''"'"'s head having folded positions extending toward each other and overlying said transverse support and the inner end of said mask.

2. A quick donning mask and foldable suspension as in claim 1 including a rear strap extending between rear portions of said lateral supports, a length adjustment between the ends of said transverse crown strap and between the ends of said rear strap.

3. A quick donning mask and foldable suspension as in claim 1 wherein the front ends of said lateral supports have each an outwardly extending end portion terminating at a location clear of the user'"'"''"'"'s cheeks and attached to the end of the respective lateral extension.

4. A quick donning mask and foldable suspension as in claim 3 wherein the pivot connection between the respective lateral support and lateral extension is in fore and aft alignment with a hinged connection.

5. A quick donning mask and foldable suspension as in claim 4 wherein the axes of said hinged connections are disposed in an angular relationship one with respect to the other.

6. A quick donning mask and foldable suspension as in claim 2 wherein the rear strap and crown strap are flexible bands.

7. A quick donning mask and foldable suspension as in claim 1 wherein there is a pivotal connection between the inner ends of said respective lateral extensions and said mask.
