  • Patent number: 5023955
    Abstract: A sound-attenuating impact-absorbing earcup comprises a shell having a plurality of generally circular recesses adjacent to the periphery of the cup which function as stiffening contours. The stiffening contours increase the effective stiffness of the earcup shell, improving its sound attenuating capability, and also concentrate applied stress onto those portions of the stiffening contours nearest the point of applied stress. Sufficient applied force causes the shell to fracture in the areas of the stress concentrators, thereby to absorb impact energy in a controlled manner without transmitting it to the head of the wearer. To further enhance its sound-attenuating and impact-absorbing capabilities, the earcup is formed of a low-tensile-strength, high-elongation, high-loss-factor material such as polyvinyl chloride or similar polymer.

  • Patent number: 4935965
    Abstract: The ear muff according to the present invention is a water-repellent material lined with thin insulation sewn into the form of a pocket which fits around the ear of the wearer to protect the ear against cold, wind, snow, or the like without substantially impairing hearing. The ear muff is kept engaged to the ear by means of an elastic loop residing in the hem of the opening of the pocket which contracts around the base of the ear, and in addition, adjacent to the elastic within the hem, a malleable earlobe clasp which the wearer clamps around the earlobe, so that the ear muff can be used by people with attached earlobes as well as by people with unattached earlobes. The lined water-repellent material comprising the pocket plays no part in keeping the ear muff engaged to the ear, and thus is made of flexible material so that it can conform to various shapes of ears.

  • Patent number: 4905322
    Abstract: An energy-absorbing sound-attenuating earcup comprises a rigid shell of an ABS terpolymer that is about 0.090 inch thick so as to crush upon impact at an applied force less than that required to crush the skull of the wearer. The shell has an inner coating of a sound-deadening rubber material to compensate for the reduced sound-attenuating capability of the thinner-than-normal shell. Spaced flanges defining a peripheral channel for receiving a cord of a helmet suspension are formed as staggered series of tabs rather than as circumferentially continuous members to facilitate crushing of the shell upon impact. Resilient earseals disposed between the shells and the wearer's ears comprise first thicknesses of standard polyurethane foam and second thicknesses of slow-recovery polyurethane foam to provide additional impact absorption while permitting the earseals to conform to the wearer's head in cold weather when the helmet is first put on.

The hard hat comprises an outer protective shell, a support webbing and a support band. The webbing supports the shell on the head of the wearer to define a space between the shell and the head. By passing the strap through the space, and attaching the pads together beneath the chin, the pads are held against the ears and the hard hat is held on the head of the wearer. The pads are of a thickness such that they can be stored in the space between the shell and the head of the wearer, thus eliminating the necessity of having to remove the pads from the hard hat when the pads are not in use.

  • Patent number: 4615050
    Abstract: A stirrup-shaped support for supporting ear protectors for example has two end parts, between which there is located an intermediate part incorporating an inner section and an outer section. When the end parts are moved away from one another, the inner section is arranged to be subjected to a tensile force while the outer section is arranged to buckle, at the same time, towards the inner section. The rigidity of the outer section is such that the force required to move the end parts away from each other is substantially constant within a predetermined range of distances between the end parts.

  • Patent number: 4551861
    Abstract: An ear pad for fastening within the ear protective guard of a helmet is formed of a thick, resilient, rubber-like sheet material that is molded with a central ear receiving pocket surrounded by bulged, cushion-forming strips which engage the wearer's head around the ear. The strips bulge away from, that is, they open towards, the helmet guard and the edges of the strips engage the helmet guard surface to thereby form resilient, compression chambers that absorb and redistribute impact shocks. A portion of the sheet surface at the pocket and adjacent the guard wall is depressed away from the guard wall to form a shallow, relatively wide, hollow chamber between the pocket and the guard wall to provide a compression chamber overlying the ear.
