SELF ORIENTED MASK HARNESS ARRANGEMENT Filed Aug. 8, 1957 2 Sheets-Sheet 2 INVENTOR. I/f/VA) w- 56 a: BY Wm M c. w i" United States Patent SELF ORIENTED MASK HARNESS GEMENT Henry W. Seeler, Dayton, Ohio, assignor to the United States of America as represented by the Secretary of the Air Force Application August 8, 1957, Serial No. 677,167 4 Claims. (Cl. 128-146) (Granted under Title 35, US. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the United States Government for governmental purposes without payment to me of any royalty thereon.
This invention relates to a harness arrangement for supporting a breathing mask and, more particularly, to a single strap harness arrangement for orienting a mask against the face of the wearer.
Breathing masks, which are used by pilots of aircraft operating at high altitudes, must be fixed against the face of the wearer at high altitude with sufiicient force to prevent escape of oxygen from the interior of the mask to the ambient atmosphere. When the mask is retained against the face of the wearer with a large force for a long period of time, it may become uncomfortable and the pilot may desire to shift the position of the mask on his face. The present invention satisfactorily solves this problem by permitting the mask to be retained with its desired force against the face of the wearer and yet be capable of being adjustable on the face of the wearer to a more comfortable position through the single harness strap arrangement of the present invention.
The occupant of an aircraft is sometimes subject to large gravity forces. These forces tend to cause the mask to slip down upon the face of the wearer and possibly hinder his vision. The movement of the mask due to the gravity forces also may cause the seal formed against the face of the wearer by the mask to become ineffective and the wearer no longer receives the needed oxygen. This invention satisfactorily solves these problems by retaining the mask in the desired position despite it being subject to large gravity forces.
An object of this invention is to provide a single strap harness arrangement for a breathing mask.
Another object of this invention is to provide a harness apparatus that retains a breathing mask in position when subjected to large gravity forces.
A further object of this invention is to provide a harness arrangement for a breathing mask that allows the mask to glide freely within the arrangement when the wearer pushes the mask to its most comfortable position.
Other objects of this invention will be readily perceived from the following description.
This invention relates to a means for orienting a breathing mask against the face of the wearer and includes a harness strap having a portion adjacent one of its ends secured to a lowermost portion of the mask. The harness strap extends through guide means secured to one side of a headgear or the like, guide means secured to an uppermost portion of the mask, and guide means secured to the other side of the, headgear. The end of the strap, which is adjacent the portion secured to the lowermost portion of the mask, has adjustment means secured thereto to hold the other end of the strap with an adjustable force to retain the mask in its oriented position. 4
The attached drawings illustrate a preferred embodiment of the invention, in which Fig. 1 is a side elevational view of the apparatus of the present invention;
Fig. 2 is a front elevational view of the apparatus of Fig. l; and
Fig. 3 is a bottom plan view of the portion of the mask having the harness secured thereto.
Referring to the drawing, there is shown a breathing. mask 10 having a single harness strap 11 secured to the lowermost portion of the mask by securing means 20 such as a rivet. The portion of the harness strap, which is secured to the lowermost portion of the mask, is adjacent one end 12 of the strap 11. The mask is secured to a. headgear 14, which the wearer has supported on his head, by the strap 11 extending through a guide member 15,v which is secured to one side of the headgear 14.
The mask 10 has a plurality of clamps 16 secured to the uppermost portion of the mask adjacent the nose of the wearer. The clamps 16 function as guide means for the harness strap 11 to pass therethrough after it has passed through the guide member 15 of the headgear 14. While a plurality of clamps 16 is shown, it will be understood that only one may be employed along the uppermost portion of the mask, if desired. After the free end 17 of the strap 11 has passed through the clamps 16, it extends through a guide member 18 on the other side of the headgear 14.
The end 12 of the strap 11 has an adjustment means such as a buckle 19 attachedto it. After the free end 17 of the harness strap 11 has passed through the guide member 18, it extends through the buckle to be held therein by friction to retain the mask in its oriented position. The exact force, which is employed to hold the mask 10 against the face of the wearer, depends upon the position in which the free end 17 of the strap 11 is held within the buckle 19, and, of course, is adjustable as desired.
By mounting the harness strap 11 so that it is attached to the uppermost portion of the mask 10 and secured adjacent the lowermost portion of the mask 10, it will be observed from Fig. 1 that substantially equal forces are applied against the uppermost portion of the mask and the lowermost portion of the mask because the portion of the strap between the clamps 16 and either of the guide members 15 or 18 and the portion between the lowermost portion of the mask and the guide member are at substantially right angles. Since the force is applied through the headgear 14 and its guide member, the resultant forces equally divide between the portion of the strap, which is disposed between the clamps 16 of the mask 10 and the guide member 15 or 18 of the headgear 14 and the portion of the strap between the lowermost portion of the mask 10 and the guide member 15 or 18 of the headgear 14. After the mask has been secured with sufficient force against the face of the wearer through adjustment of the strap by the buckle 19, the mask 10 may be moved as desired without changing the force exerted on the mask. Thus, the harness strap arrangement of the present invention maintains the mask in oriented position against the face of the wearer at all times.
Since the forces are divided equally between the uppermost portion of the mask and the lowermost portion of the mask, the mask retains its position against the face of the wearer even when subjected to large gravity forces because of the harness arrangement. Any tendency for the mask to slip due to the large gravity forces is prevented by the force of the strap 11 acting against the mask 10.
An advantage of this invention is that the harness arrangement produces substantially the same force at both the top and bottom of the mask to thereby keep a uniform force upon the mask against the face of the wearer to maintain the desired seal between the mask and the face of the wearer. Another advantage of this invention is that it permits easy adjustment of the mask by only one buckle on the face of the wearer w-ithout changing the force holding the mask against the face of the wearer.-
For purposes of exemplification, a particular embodiment of the invention has been shown and described-ac cording to the best present understanding thereof. However, it will be apparent that changes and modifications in the arrangement and construction of the parts thereof may be resorted to' without departing from the true spirit and scope of the invention. t
