Hearing protection of helmets, especially for forest workers

摘要

Including: hearing protection (33) with protective helmet (30),Especially the forestry workers The hearing aid (33) is composed of two hearing aids (34a, 34B), each of which has a fork bracket (37a, 37B), one of which has a hearing aid bracket (35a, 35b) and a rotating plate (37a), 37 (b) a tilted joint, and the associated support rods (37 A, 37 b) can be tilted in a wide position and a retracted position in two ways. The rotating plate remains rotating on part (80A) of the reception(80B) hull coupling (30). The specified offset spring between the rotating plate and the bracket (37 A, 37 b) turns the bracket (37 A, 37 b) in front of the bracket (37 A, 37 b) so that it is adjacent to the top that determines the width and retraction position of the bracket. The receiving part (80A, 80B) is butted with the hull interior (30). Therefore, turn the hearing protectors (34a, 34B) to the inactive position in the helmet
