Abstract
The present invention relates generally to a device for locating ear-muffs arranged on a helmet or the like by means of bearing members arranged in the helmet to pivotally receive attachment members, each of said members cooperating with an ear-muff cover by a clamp-shaped arm. The attachment members being with their upper ends of said arms located inside the helmet and displaceable arranged in a longitudinal direction. In this way any desired location of said ear-muffs -- parking position within the helmet or working position covering the ears -- could easily be established.
Claims7
An ear cover and helmet combination including means for adjustably attaching said ear cover to the interior of a helmet comprising a shackle attached to said cover and having an extending shank formed by a pair of parallel spaced arms interconnected by an integral loop at their ends, a bearing formed in the side of said helmet, a rotatable pin removably journalled within said bearing and extending into the interior of said helmet between the arms of said shank, the bearing having an axial slot and an undercut circumferential groove within the bearing, the extending portion of the pin having a radial boss movable through said axial slot and adapted to engage the interior frontal edge of said undercut circumferential groove of the bearing to prevent axial displacement of said pin, a pair of lands formed chordally on a member extending from said rotatable pin, said pair of lands cooperating with said shank to secure said shackle for conjoint rotation therewith and for longitudinal displacement thereon, permitting said shackle and said cover being selectively movable into and out of the interior of said helmet while being worn and permitting said pin and shackle to be removed from said helmet.
