A blower device for a respiratory protection system comprises a fan for a generation of an airflow and comprises one or more filter element that is flowed through by the airflow. The fan is arranged at least partly beside the one or more filter element. The airflow is deflected between the fan and the filter element.

Blower device for a respiratory protection system

A mouth protection device for a respiratory protection system, in particular a blower respiratory protection system, includes at least one mask base body which is configured to cover a mouth and/or nose region of a user and which delimits a breathing zone at least partially, and includes at least one breathing air supply line, which is connected to the mask base body and delimits at least one breathing air channel that ends in the breathing zone and is configured for guiding an active breathing air flow, wherein the mask base body is made at least largely of a flexurally soft material, the mask base body being made at least largely of a textile material.

Mouth protection device for a respiratory protection system

An optical glare protection filter for a glare protection device includes at least one liquid-crystal cell with at least one liquid-crystal layer and at least one first electrode layer for orienting crystal molecules of the at least one liquid-crystal layer, and with at least one first contact element for electrically contacting the at least one first electrode layer. The optical glare protection filter may also include at least one second contact element for electrically contacting the at least one first electrode layer, which is substantially spaced apart from the first contact element.

Optical glare protection filter

The invention is based on a protection device, in particular a glare-protection device, with at least one optical glare-protection filter comprising a nose cut-out, with at least one sensor unit, which is provided to capture a work state and to control, depending on this, a permeability of the glare-protection filter, with at least one shield unit, in which the at least one glare-protection filter is fixedly accommodated, and with at least one head-fastening unit for a fastening to a user's head. It is proposed that the protection device comprises at least one adjusting unit, by which a position of the at least one shield unit is implemented in such a way that it is movable with respect to the at least one head-fastening unit in a defined manner.
