Title
(DE) VARIABLER GEHÖRSCHUTZ
(EN) VARIABLE HEARING PROTECTION
(FR) PROTECTION AUDITIVE VARIABLE
Abstract
(DE)
Der variable Gehörschutz besitzt einen Verstellmechanismus (3), mit welchem die Dämpfung in einem durch den Gehörschutz verlaufenden Kanal (2) verändert werden kann. Hierzu ist im Verstellmechanismus eine Scheibe (16) angeordnet, welche sich über den ganzen Kanalquerschnitt erstreckt und Sektoren unterschiedlicher Dicke aufweist. Die Scheibe (16) ist drehbar gegenüber einen ersten Barrierenteil (13), in welchem eine Öffnung (15) angeordnet ist. Je nachdem, welcher der Sektoren mit der Öffnung (15) zur Deckung gebracht wird, kann so eine starke oder schwache Dämpfung eingestellt werden. Indem die Scheibe 16 den ganzen Querschnitt des Kanals (2) abdeckt, können ein Durchtritt von Schmutz verhindert und unerwünschte plötzliche Druckänderungen vermieden werden.
(EN)
The variable hearing protection comprises an adjusting mechanism (3), by which the attenuation can be varied in a channel (2) running through the hearing protection. For this purpose, in the adjusting mechanism a disk (16) is disposed, which extends across the entire channel cross-section and has sectors with varying thicknesses. The disk (16) is disposed rotatably relative to a first barrier part (13), in which an opening (15) is disposed. Depending on which of the sectors is moved to be congruent with the opening (15), in this way strong or weak attenuation can be set. In that the disk (16) covers the entire cross-section of the channel (2), penetration of dirt can be prevented and undesirable sudden pressure changes can be avoided.
(FR)
Cette protection auditive variable possède un mécanisme de réglage (3) qui permet de modifier l'atténuation du bruit dans un conduit (2) s'étendant à travers la protection auditive. A cet effet, un disque (16) est disposé dans le mécanisme de réglage, disque qui s'étend sur toute la section du conduit et présente des secteurs d'épaisseurs différentes. Le disque (16) est rotatif par rapport à un premier élément barrière (13) dans lequel est disposée une ouverture (15). Selon le secteur qui est amené en coïncidence avec l'ouverture (15), on peut régler une atténuation du bruit plus ou moins forte. Comme le disque (16) couvre toute la section du conduit (2), on empêche le passage des impuretés et on évite de brusques variations de pression indésirables.
