Claim:
A forehead support constructed and arranged to be connected to and support a respiratory mask, comprising: a bridge constructed and arranged to engage a forehead of a user, the bridge having a first side and a second side, the bridge also having a plurality of first adjusting points spaced along the first side and a plurality of second adjusting points spaced along the second side; a first arm having a bridge end and a mask end, the first arm bridge end having an engagement mechanism constructed and arranged for selectively engaging each of the plurality of first adjusting points, the first arm bridge end engagement mechanism comprising a pair of extending portions separated by a space, the extending portions constructed and arranged to be selectively movable relative to one another between an expanded position where the extending portions are separated by the space and a compressed position where the separating space is reduced, at least one of the extending portions having a stiffness greater in a horizontal direction than in a vertical direction; and a second arm having a bridge end and a mask end, the second arm bridge end having an engagement mechanism constructed and arranged for selectively engaging each of the plurality of second adjusting points, the second arm bridge end engagement mechanism comprising a pair of extending portions separated by a space, the extending portions constructed and arranged to be selectively movable relative to one another between an expanded position where the extending portions are separated by the space and a compressed position where the separating space is reduced, at least one of the extending portions having a stiffness greater in a horizontal direction than in a vertical direction; wherein, selective movement of the first arm bridge engagement mechanism between the plurality of first adjusting points alters a spacing distance between the first side of the bridge and the first connecting portion and selective movement of the second arm bridge engagement mechanism between the plurality of second adjusting points alters a spacing distance between the second side of the bridge and the second connecting portion.
