Combination headset and face mask device
First Claim
1. An improved headset and face mask combination device wherein the headset is of the type having a flexible headband adapted to overlie the wearer'"'"'s head and terminating in ends adapted for disposition opposite the wearer'"'"'s ears and each such end in turn provided with an ear cup attached thereto and having generally rotational movement with respect to the end to which it is attached and at least some pivotal back and forth lateral movement in a plane defined by the transverse extent of said headband and a face mask rotationally movable between upper and lower positions supported from said headband;
- the improvement comprising, restraining means for essentially eliminating possible relative rotational motion of said ear cups relative to said headband terminal ends, said restraining means including a bridge member overlying portions of each said headband end, said bridge member further including means for fixedly attaching itself to said ear cups at two laterally-spaced locations on said ear cups and on either side of said headband ends.

Abstract
Motion limiting means are provided on a combination headset and face mask device to eliminate the necessity of a rear head strap which is normally utilized to position the headband and to prevent its relative movement on the wearer'"'"'s head when the face mask is adjusted as between upper and lower positions. This is accomplished by the provision of a bridge member which in essence pins the terminal band portion of the headband against its proximal ear cup thereby enabling the headband and ear cups to act as an unit and thus increase the frictional force available against the face mask moving the headband out of position.
