发明名称 Oxygen mask retention device and method for retaining an oxygen mask
摘要 A retention device and method for retaining an object, including preferably a gas mask, in position proximate a user's mouth. The retention device includes straps coupled to both sides of the object and having at ends thereof ear pieces. The ear pieces fit over the ears, and are configured to receive the strap at a point proximate the tragus portion of the ear, causing pulling forces to be on the posterior center portion of the ear rather than on the top of the ear. The ear pieces have a downwardly exterior anterior leg and a downwardly extending posterior leg. In one embodiment, the ear pieces are substantially U-shaped. In another embodiment, the ear pieces are substantially ring-shaped.
