Embodiment Construction

[0022] figure 1 First of all, for illustration purposes, a known half-mask 1 for respiratory protection is shown, which can be equipped with a gas filter or a particle filter if necessary. The respiratory half-mask 1 can be fastened on the head and neck of the wearer by means of a strap 8 to which the head piece 9 is connected in the upper region. The straps 8 have adjustment elements 10 at various points, which allow the wearer to change the length of the respective strap 8 and thus place the mask 1 in the desired position. In contrast to a full face mask, it is essential for a half mask 1 that the mask body 2 only covers the wearer's mouth and nose. The mask body 2 has not only a lateral connection 11 for fastening a filter, but also a frontally arranged connection 12 for an exhalation valve. In order to fix the mask body 2 on the strap 8, a holding element 13 is provided, which can be aligned in its position by means of a locking element 14 arranged in the upper region of...

The side elements (5a, 5b) are separately connected, by means of a hinge (7), to the front element (6) in a hinged manner.

Description

technical field [0001] The invention relates to a respiratory protection half-mask with a mask body having a soft elastic base body and a carrier part arranged at least partially inside the base body. In this case, the carrier part has a front element with a first connection and lateral elements arranged towards both sides of the front element, which each have two connections. The first and the second connection are designed in such a way that various components of the respiratory protective mask, such as the filter element, the exhalation valve, the speaking membrane and / or the external air supply, can be attached to the first and the second connection. Background technique [0002] Half masks for use in light respiratory protection are well known and are usually equipped with replaceable particle and / or gas filters. A half-mask, which differs from a full-face mask and only covers the wearer's mouth and nose, is fastened to the wearer's head by means of straps. The strap ...
