摘要： An ear-plug comprising a plug-like body of fine glass wool and a surrounding casing of thin polyethylene film having low friction vis-a-vis the auditory canal. The glass wool is exposed at the surface of the expanded end of the ear-plug not to be inserted into the auditory canal. The ear-plug is fixed as to shape by means of a circumferential heat weld in the polyethylene film located where the expanded part of the ear-plug begins.

摘要： An attachment device in the form of a bearing housing (10) and an arm (38) projecting out through an opening (44) in the housing. The arm is supported in a bearing support (42) in the housing and serves to carry, at the end opposite the housing, an ear muff to move with a rocking motion between a stationary rest position and a position wherein the earmuff exerts a pressure around the wearer's ear. A separate spring component (44), preferably annular in form, is rotatably supported in and prestressed to bear against, on one side, an adjustable spring support (48), which is located inside the housing and remains stationary during the rocking motion, and, on the opposite side, the end (52) of the arm (38) located inside the housing. By this arrangement there is exerted on the said end of the arm a controlled force directed away from the spring support (48) for the purpose of stabilizing the arm in its two positions. The spring support may consist of a rocker, the position of that part (56) of the rocker in which the spring component is supported being adjustable against an adjusting means (16) with respect to the nearer end of the arm to permit alteration of the prestressing of the spring component. The adjusting means consists of a cover (16) with an annular collar (30) of thickness varying along the extent thereof. The collar rests against the inside of the ring flange (32) of a base (12), which is rotatable with respect to the said adjusting cover.

摘要： The casings for two ear-pads are adjustably mounted on opposite ends of an arcuate headband by means of a pair of rivet-like elements, each of which extends through an elongate slot in one end of the headband, and a central opening in the associated ear-pad casing. Each rivet-like element has an enlarged-diameter cylindrical head on its inner end and an enlarged, rectangular head on its outer end which is slidable in a correspondingly shaped recess in the headband to allow adjustment of each casing in the longitudinal direction of its associated slot. A plurality of flexible, washer-like supporting members are pressed over the inner end of each element resiliently to engage opposite sides of a casing around its central opening frictionally to resist movement of each casing relative to the headband.
