Abstract (en)
[origin: EP0102617A2] The device is intended, in particular, for safety helmets for people travelling together on one motorbike. It has for each helmet a mouthpiece (4, 4') and an earpiece (2, 2') and an acoustic lead (6, 6', 7, 7'), which connects the mouthpiece of the one helmet to the earpiece of the other helmet, for pneumatic sound transfer. The earpiece consists of a soft, elastically deformable material and is to be arranged without attachment means between the inside wall of the helmet and the head of the wearer. This is made possible by the fact that the height of the earpiece (2, 2') perpendicular to its base surface is greater than the distance between the inner wall of the helmet and the head of the helmet wearer. A tube (3, 3') supporting the mouthpiece (4, 4') and the acoustic leads (6, 6', 7, 7') for the connection to the other participant are attached to the earpiece (2, 2'). <IMAGE>
