Abstract

Ear defenders (33) for fastening to a protective helmet (30), in particular for forestry workers, are described. The ear defenders (33) have two ear protection devices (34a, 34b), each of which has a supporting strap (37a, 37b) which is designed in the manner of a fork and has an ear protection capsule (35a, 35b) mounted pivotably thereon, and a rotary plate which is connected to the supporting strap (37a, 37b) by a tilting joint and in relation to which the supporting strap (37a, 37b) can be bistably tilted into a swung-out and a swung-in position. The rotary plate is mounted rotatably in a receiving part (80a, 80b) attached to the helmet (30). A strap spring arranged between the rotary plate and the supporting strap (37a, 37b) prestresses the supporting strap (37a, 37b) to bear against stops which fix the swung-out and the swung-in position of the supporting strap. The receiving part (80a, 80b) is attached on the inside to the helmet (30). The ear protection devices (34a, 34b) can therefore be rotated into a parking position within the helmet.

Description

technical field [0001] The present invention relates to an ear protection device intended to be fastened to a protective helmet, in particular for forestry workers, the ear protection device comprising two ear protectors each comprising: a forked support bracket, the ear protection devices being pivotably supported on the forked support bracket; a rotating plate, which is jointedly connected to the support bracket, the support bracket being bi-directionally stable (bistably) relative to the rotating plate ) tilts into an extended position and a retracted position; and a receiving portion, which can be attached or be attached to a helmet, in which the rotating plate is rotatably supported, and which can be Pivoting between an operating position defined by a stop and a rest position. Background technique [0002] Such an ear protection device is known from DE 10 2007 011 110 A1 to be referred in more detail further below. [0003] A protective helmet comprising such ear prot...
