Abstract: A system which is composed of a blower unit for a powered air purifying respirator and an electrically powered accessory. The blower unit has a blower device and a battery for powering the blower device. And the accessory is equipped with a power connector. The blower unit provides a power outlet for connection with the power connector. The power connector has a plug. Furthermore the power connector has an unplug lever for retracting the plug for unplugging. The unplug lever and the plug are connected by a pivot joint that forms a pivot axis. The unplug lever forms a handle arm and a counter arm that extend away from the pivot joint in opposite directions.

Abstract: Protective headgear including central, left lateral, and right lateral trunks, and which may include at least one external, remote handle for directing air flow.

Abstract: A protective headgear (1) comprising: a protective helmet (20) that defines an interior space (31), that comprises an inward major surface, and that comprises a forward window with a windowpane (27); a head suspension that is connected to the helmet; and an air supply module (50) mounted at least partially within the interior space defined by the helmet, wherein the air supply module comprises central, right lateral, and left lateral trunks (53, 54, 55) that are configured so that when the module is mounted within the interior space defined by the helmet, selected central, left and right areas of the inward major surface of the helmet combine with the central, left lateral and right lateral trunks of the air supply module to respectively define a central air supply passage and left and right lateral air supply passages for delivering air to a wearer of the protective headgear, and, wherein the air supply module comprises an external, remote handle (70) that is remotely connected to an air valve that is operat

Abstract: There is provided a welding helmet (1) that has a protective shield (2) and a head suspension system (6). The protective shield and the head suspension system are pivotally connected to each other for swiveling the protective shield relative to the head suspension system about a pivot axis in opposite directions upward or downward between a protective position, in which the protective shield covers a wearer's face, and an up-raised position, in which the protective shield uncovers the wearer's face. The welding helmet further has a stop mechanism that restricts downward swiveling beyond the protective position. The stop mechanism (10) is adjustable by a worm gear mechanism (11, 12) between a low position and a high position. In the low position the protective position of the protective shield is offset downward with respect to the high position.
