Abstract

DC60 (05/04/56) describes ear protection parts (33) attached to helmets (30), especially for forest workers. The ear protection piece (33) consists of two ear protectors (34a, 34b), each of which consists of a repair-like backplate (37a, 37b) containing an ear protection bag (35a, 35b) located on the swivel plate. can cycle and a swivel plate connected to the support plate (37a, 37b) by a tilt joint in which the support plate (37a, 37b) can be tilted into the extended or retracted position. in a bi-stable manner The swivel plate is supported in a swivel manner in the receiver (80a, 80b) that is attached to the helmet (30). A spring connection is mounted between the swivel plate and the support plate (37a, 37b) pre-stressed. To the support bracket (37a, 37b), attach it to the next stop that limits the stretch position. The support parts (80a, 80b) are attached to the interior of the helmet (30), so the ear protectors (34a, 34b) can be rotated into the helmet's stop position. Describes the ear protection parts (33) that are attached specifically to the helmet (30). especially for forest people Ear protection parts (33) consist of two ear protectors (34a, 34b), each of which consists of a repair-like backplate (37a, 37b) containing an ear protection bag. (35a,35b) The bracket is on the swivel pad. and the swivel plate connected to the support bracket (37a, 37b) by tilting joints in which the support bracket (37a,37b) can be tilted into the extended or retracted position. in a bi-stable manner The swivel plate is supported in a rotatable manner in the receiver (80a,80b) part at It is attached to the helmet (30). The connecting spring mounted between the swivel plate and the support plate (37a, 37b) is pre-stressed to the support plate (37a,37b) to attach on the next stop limiter. stretch position and retracting of the backing keys The receiver parts (80a, 80b) are attached to the inside of the helmet (30). The ear protectors (34a, 34b) can therefore be bolstered into the stop position of the helmet.
