Eye and hearing protection

摘要

A safety unit combining eye and hearing protection in which retention of earcups on the head of wearer is by resilience of separate side arms carrying the earcups. The resilience is resisted by a provision of a rigid frame to spectacles, or a rigid beam to goggles. Snap fitting of arms to the frame or beam enables use of the arms with either spectacles or goggles. The spectacle lens or goggle visor is separate from the rigid frame or beam.
