Abstract: A two piece dual mode earplug including an integrally molded elongated member having a nose end and an open rear end and a channel extending through. An integrally molded insert member is formed with a base portion and a rod portion and with the rod portion seated within the open rear end of the elongated member and includes an attenuation filter integrally molded as part of the rod portion and includes first and second openings located on each side of a chamber and with the size and length of the openings together with the chamber providing attenuation of impulse noise. The insert member also includes the base portion integrally molded to have a third opening larger than the first and second openings in the rod portion and with the first, second and third openings together forming a passageway through the insert member to the channel extending through the elongated member.
Abstract: The invention describes an ear protector (1) comprising a resilient band (2), the free ends of which each have arranged thereon an earplug (4). The band (2) includes a first area (2a) whose center line (2a?) merges under an angle ? with an additional area (2b). When in use, the band is pivotable in the user's ears about an axis of rotation (3?) extending through the earplugs (4). In order to implement such an ear protector in a structurally simple manner such that noise disturbance caused when the band (2) rubs on a piece of clothing can be reduced or eliminated, it is suggested to implement a chin area (2a) and a cheek area (2b) between which the angle ? is provided, said angle ? ranging from 35° to 90°, preferably from 45° to 70° and even more preferably from 50° to 60°.
Abstract: An earplug composed of an injected molded resilient polymeric material for insertion into an ear canal by a fingertip of a user, including an elongated member having a nose portion formed as a curved front end. An open cup shaped rearward extending flange located at the end of the elongated member opposite to the nose portion and with the open cup shaped rearward extending flange configured to receive the fingertip of the user. The elongated member including at least one flange element located intermediate the nose portion and the open cup shape flange. The nose portion and the flange element having a generally curved shape to extend into and conform to the wall of the ear canal.
Abstract: A single strap respirator mask with a head harness, including a respirator mask, which has a cup shape to fit over the face of a user. The mask includes a pair of ear portions located at and extending from opposite sites of the mask and each ear portion tapers in width from an inside position to an outside end as it extends from the mask. A single strap extends around the head of a user and is attached to the outside end of each ear portion. A head harness is attached to the single strap and lies against the back of the head of a user. The head harness has a width substantially larger than the width of the strap to broaden the support of the strap against the back of the head of a user.
