Abstract: A device (10) is disclosed for mounting a hearing protector (90) on each side of a hard hat, pressing the hearing protectors at a substantially constant force about the ears and moving them in oppositely incline planes between an operative wearing position (W) and an extended inoperative pressure relieved stored position (R). Each device comprises support means (20) including a pivot (28) adapted for attachment to and retained to a side of the hard hat (H), by retainer means (30), guide means (40) (50) including at least one incline surface (44) (54) and a key boss (46) (56) projecting into a key hole shape slot (74) in a rigid central end portion (72) of a resilient flexible support arm (70) secured by releasable clamping means (60).
