Arrangement for securing a hearing protector to a helmet and a helmet with such an arrangement

Abstract: Arrangement for securing a hearing protector to a helmet, which arrangement comprises a cap holder piece (102) and a helmet piece (101). The cap holder piece contains a rotary plate (103), a bistable element (104) and a cap holder element (105), which is secured by means of the bistable element to the rotary plate to allow a hearing protection, secured to the cap holder element, to take up a tilted out and a tilted in position relative to the rotary plate. The helmet piece comprises means (112, 112′) of attachment to a helmet and a receiving piece (111), in which the rotary plate is secured, able to turn about an axis of rotation, which receiving piece includes a resilient tongue (113) essentially parallel to the axis of rotation and a first stop piece (116) which, under the action of the resilient tongue and in cooperation with a second stop piece (132) arranged on the rotary plate, releasably maintains the rotary plate in a first rotational position relative to the receiving piece. To prevent the cap holder piece from accidentally leaving the first rotational position, the arrangement includes a first projection (119) extending from the receiving piece essentially parallel to the axis of rotation, which in the first rotational position limits the motion of the rotary plate toward the resilient tongue by thrusting against the cap holder piece.
