A respiratory mask 2 includes: a mask body 4 including a mask shell 41 and a mask cushion 42; a front cover 32 hinged to the mask shell 41, and having a support arm 320 extending upwardly; a forehead support unit 3 having a forehead frame 31 connected to a top end of the support arm 320, and a forehead pad 33 connected to a rear side of the forehead frame 31; and an adjustment unit 6 connected to at least one of the mask shell 41 and the front cover 32, which allows relative movement of the mask shell 41 and the front cover 32 so that the mask body 4 can abut against the user's nose with an appropriate abutment pressure. A hinge unit has a pin 51 located in holes 53 which allows tilting between the mask shell 41 and the front cover 32. The tilt is controlled using a resilient adjustment member 61 which engages the front cover 32 with tabs 62 and is releasable by pinching, or which may be a screw 65 (see figures 11, 12). |
