Abstract
Device for a safety helmet with ear mufflers, where each ear muffler is mounted on an arm which is mounted on the helmet pivotally in a plane parallel to the longitudinal direction of the helmet. The mufflers with arms are also pivotal in a plane across the longitudinal direction of the helmet, adjustable from a noise-deadening position where the mufflers are against the ears, to an out-swung and stopped position.
