Abstract
A respiratory mask including a flexible seal member that is formed to receive nasal and/or oral portions of a user's face. The flexible seal member is adapted to resiliently deform against the facial structure of the user to form a seal therewith when the mask is secured to the user's head by suitable straps or related headgear. The mask further includes a single block-like spacer for limiting deformation of the mask seal when the mask is engaged with the user's face and an adjustment mechanism for adjusting the position of the spacer. A presently preferred adjusting mechanism includes a flexible strap member upwardly extending from the mask and along which the spacer may be conveniently and selectively positioned.
