BESPIRATORS, AND THE Application filed December 1'7, 1925, Serial No. 75,907, and in Germany December 24, 1824.

The present invention relates to. a system of straps to hold a respirating device such as a respirator, a mask, a breathingdevice or similar appliances to the head of a human body. The object of the invention is to provide a structure of straps of this kind, which hereinafter is called a harness, that can be very readily and economically made, the harness being exceedingly simple and economic of construction and capable of being expeditiously and conveniently applied or removed. Another object of the invention is to provide a harness of this kind that will maintain the respirating appliance in place on the face in proper position, but will not cause discomfort to the wearer, irrespective of. the shape of the head.

The invention consists in the novel construction and combination of the several" 2 parts as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had .to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Fig. 1 is a perspective view of a harness in connection with a mask,

Figs. 2, 3 and 4 are modifications 'of the harness shown in Fig. 1, and

Fig. 5 is a perspective view of a harness in connection with a respirator.

In the construction shown in Fig. 1 the harness, which is supposed to be used in connection with a mask a, comprises a pad or fiat member I) and a certain number of straps hereinafter more fully described. By a slip connection the pad I) is engaged atv its lower end by a nape strap a connected at its ends with the two sides of the mask a. The slip connection consists of a loop d through which the nape strap 0 passes, and which is attached to the pad b by any suitable means. From the upper end of the pad 1) extends a top strap 6 the forward end of which is connected with a mask a by two transversal straps If found convenient a front strap 9 may be provided to form a prolongation of the top strap 6, and if desired further horizontal transversal straps k may be used to connect the pad b with the sides of the mask, so as to give the pad a greater steadiness. Of course buckles i may be used as usual in similar structures for securing the necessary adjustability.

In the construction shown in Fig. 2 the front strap is bifurcated thev two branches being made integral with the transversal straps to form prolongations thereof.- To connect the strap 6, the transversal straps f and the bifurcated front stra g in this figure a slotted member forme by a plate m is shown having diagonal slots n, through which the straps f, 9 pass thus forming a 3111i connection.

In. the construction shown in Fig. 3 the two parts of the bifurcated front strap are made of one; continuous tape or belt passing through .the slot of a second slotted member of attachment 0, thus the combined or continuous front and lateral strap passes through the two members of attachment m and 0 following the lines of an M. It is evident that by these means great convcnience will be given to the wearer. Instead of 75 making use of bucklm, or in addition thereto, parts p of the various straps may be made elastic as indicated.

The construction shown in Fig. 4 differs from those described above in as much as the slip connection between the nape strap and the pad 6 consists of two loops d instead of one. These two loops are attached to the pad at a certain distance from one another to avoid inconvenient pressure on the sensitive part of the nape.

In the. construction shown in Fig. 5 the two loops d attached to the pad I) has the effect to protect in a similar manner the sensitive part of the nape from disagreeable pressure. In this construction, in which the harness is applied to a respirator or mouthbreathing appliance, the ad is made in one with the top strap, the ront end of which is connected with the transversal straps by a ring.

I claim 1. A harness for respirating appliances such as masks, respirators and the like, comprising a pad arranged to lie at the back of the head, a center top strap attached to the upper end of the pad and extending forwardly therefrom and adapted to lie on top of the head, two transversal straps connected with the sides of the respirating appliance, slip connections between said transversal er end of said pad and the sides of said res-- pirating appliance.

2. A harness for respirating appliances such as masks, respirators and the like,

comprising a pad arranged to lie at the back of the head, a center top strap attached to the upper end ofthe pad and extending forwardly therefrom and adapted to lie on top of the head, two transversal straps connected with the sides of the respirating appliance, a plate having diagonal slots attached to the center strap, a bifurcated front strap made in one with the two transversal straps and passing through the diagonal slots of said plate to form a slip connection between said center top strap, said transversal straps and said bifurcated front strap, and strap connections between the lower end of said pad and the sides of said respirating appliance.

3. A harness for respirating appliances such as masks, respirators and the like, comprising a pad arranged to he at the back of the head, a center top strap attached to the upper end of the pad and extending forwardly therefrom and adapted to lie on top of the head, two transversal straps connected with the sides of the respirating appliance, slip connections between said transversal straps and the front end of said center top strap, a nape strap extending continuously from one sideof the respirating apparatus to the other and having its opposite ends attached to the two sides of said respirating apparatus, and a slip connection between said pad and said nape strap.

4. A harness for respirating appliancessuch as masks, respirators and the like, comprising a pad aranged to lie at the back of the head, a center top member extending forwardly from the upper end of said pad and adapted to lie on top of the head, a slotted member attached to said center top strap, a second slotted member attached to said respirating appliance, and a combined front strap and two transversal straps connected at thein opposite ends with said respirating appliance and slidably passing through said slotted members whereby said combined transversal straps and front strap form a strap slidably connected with said center front strap and appliance.

5. A harness for respirating appliances, comprising a fiat member arranged to lie at the back of the head, a slotted member, a center top member extending from said fiat member to said slotted member and adapted to lie on top of the head, a combined front strap and two transversal straps connected at at least three points to the respirating appliance and slidably passing through said slotted member, whereby said combined front strap and transversal straps form a member slidably connected with said center front strap, a nape strap extending from one side of the respirating appliance to the other and having its ends attached to the sides of the respirating appliance, and a slip connection between the lower end of said fiat member and said nape strap.

In testimony whereof I have signed my name to this specification.

ALEXANDER BERNHARD DRKGER.
