A cross-direction guide is provided for positioning the support in the direction at right angles to the retaining arm length axis. Independent claims are also included for (a) a support with a support cushion (14) comprising an elastomeric band integrally combined with a fork-like mounting, (b) a support with a retaining arm which is pivotable relative to the mask basis body (2), and with a support which is not movable relative to the adjustment device, and (c) a support combining the features of the previous two supports, the cushion being movable along the retaining arm length axis, where it can be fixed into position.
