Title:
Ear protective equipment attached to a protection helmet
Document Type and Number:
Japanese Patent JP6046614
Kind Code:
B2
Abstract:
An ear protection to be fastened to a protective helmet, particularly for forestry workers, is described. The ear protection comprises two ear protectors each of which comprises a fork-like supporting bracket comprising ear protection capsule pivotably supported thereon and a rotary plate connected to the supporting bracket by a tilting joint in relation to which the supporting bracket can be bistably tilted into an extended and into a retracted position. The rotary plate is rotatably supported in a receiving part attached to the helmet. A yoke spring disposed between the rotary plate and the supporting bracket pre-stresses the supporting bracket to abut on stoppers defining the extended and the retracted position of the supporting bracket. The receiving part is attached to the inside of the helmet. The ear protectors are therefore rotatable into a parking position within the helmet.
