Front face of a headgear for a respiratory mask

The sole FIGURE is a front view showing a front face of a headgear for a respiratory mask according to my new ornamental design.

The sole FIGURE illustrates the headgear in a flat condition. When donning the headgear, it generally assumes the shape of the user's head.

The thickness of the headgear forms no part of the claimed design.

The broken lines indicate environment or structure of the front face of a headgear for a respiratory mask and form no part of the claimed design.

The stippling represents the border between claimed and unclaimed subject matter and forms no part of the claimed design.

The ornamental design for a front face of a headgear for a respiratory mask, as shown and described.
