Forehead pad for a breathing mask and method for making the same
摘要:
A forehead pad for a breathing mask includes a substantially dimensionally stable first wall element and an elastomer second wall element coupled to the first wall element. The second wall element has a contact zone adapted to contact a surface of a user in use. The first and second wall elements define a filling-material-receiving chamber adapted to receive a filling material.
