Abstract: A glasses device, in particular ski goggles, sunglasses, motorcycle goggles, or the like, has a see-through unit, which includes at least one darkening element, in particular a liquid crystal cell, which is configured for darkening at least one subregion of the see-through unit, and has a light sensor unit, which is configured to generate a sensor signal dependent on an ambient brightness, which is the basis for a degree, in particular set automatically, of an, in particular variable, darkening of the darkening element, wherein the glasses device has a switch-off unit, which provides at least one, in particular manually operable, switch-off function for the sensor signal of the light sensor unit.

Abstract: A sun protection device, in particular a pair of sunglasses, comprises at least one optical sun protection filter having at least one liquid crystal cell, wherein the optical sun protection filter comprises at least one photochromatic protection element whose transmittance changes in particular at least depending on the solar irradiation.

Abstract: 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.

Abstract: A blower device for a respiratory protection system comprises a fan for generating an airflow, further comprises at least one filter element which is configured to be flown through by the airflow, comprises a housing unit accommodating the fan and the at least one filter element and comprises an air conveying channel, which accommodates the filter element and is configured for guiding an airflow between the filter element and the fan, wherein the air conveying channel is configured for a deflection of an airflow between the fan and the filter element, wherein the air conveying channel is embodied separately from the housing unit and the at least one filter element is fixedly integrated in the air conveying channel.

Abstract: A blower device for a respiratory protection system comprises a fan for a generation of an airflow and comprises at least one filter element that is configured to be flowed through by the airflow, wherein the fan is arranged at least partly beside the at least one filter element, wherein the airflow is deflected between the fan and the filter element.

Abstract: The invention is based on a sun protection device, in particular sunglasses, with at least one optical sun protection filter comprising at least one liquid-crystal cell, and with at least one sensor unit, which is configured for capturing a solar irradiation. It is proposed that at least one sensor cover, which covers a sensor surface of the at least one sensor unit at least partly and which is, at least partly, at least substantially opaque with respect to an irradiation of a visible light spectrum.

Abstract: 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.
