Patent ID: 11985474

Abstract:
An adapter assembly for attaching a circumaural device to a mounting interface on a helmet comprises a fastener element configured to releasably couple to the mounting interface. A pressure relief assembly coupled to the fastener element has a pivoting subassembly and an adjustment subassembly. The pivoting subassembly I pivotable about a pivot axis and has a range of travel between an upright position and an extended position. One or more attachment arms have a proximal end coupled to the pressure relief assembly and a distal end for attaching the circumaural device. The adjustment subassembly has a manually operable control portion to cause pivoting movement of the pivoting subassembly toward the upright position to decrease a pressure of an attached circumaural device on a wearer's head or toward the extended position to increase a pressure of an attached circumaural device on the wearer's head.
