Headgear for breathing mask

Abstract

An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.

         79 . The interface assembly of  claim 71 , wherein the rear portion comprises a halo portion. 
     
     
         80 . The interface assembly of  claim 79 , wherein the rear portion comprises a cradle structure that extends in a vertical direction along the back of the user's head. 
     
     
         81 . The interface assembly of  claim 71 , wherein the support portion is a portion of the frame. 
     
     
         82 . The interface assembly of  claim 71 , wherein the interface assembly comprises a clip comprising a hook-shaped end portion between the mask and the headgear. 
     
     
         83 . An interface assembly, comprising:
 a nasal-oral mask; and   a headgear coupled to the mask at one or more mounting points;   wherein the mask comprises:
 a frame; 
 a seal that is configured to seal around a mouth of a user and on an underside of a nose of the user; and 
 a support that extends upwardly from the frame along each side of a nose portion of the seal to provide lateral support to the nose portion of the seal, the support portion being removably coupled to the frame. 
   
     
     
         84 . The interface assembly of  claim 83 , wherein the supports are permanently coupled to the frame.
