  • Ear-protection cup for ear muffs or head-phones
    Patent number: 5241971
    Abstract: An ear-protection cup for ear muffs or headphones comprising a cup-shaped frame and a resilient sealing member located at the peripheral edge thereof, by means of which the ear-protection cup can be brought into abutment with an annular shaped part of a user's head located around the ear. The frame is composed of a rigid, cup-shaped outer shell and an inner wall spaced from the outer shell and extending for a substantial way between the inner parts of the outer shell to which it is rigidly connected. The inner wall thus defines between itself and the outer shell an intermediate space in which a layer of elastomeric material is arranged compressed between the outer shell and the inner wall.
