Personal protection system including a hood with a transparent face shield and control buttons on the face shield

摘要

A personal protection system (30,178,290) including a helmet (32,180) to which a garment (102,236) is mounted. The helmet (32,180) includes an electrically powered assembly such as a fan (92,266,268,272). At least one button (120,134,262,264) for regulating operation of the electrically powered assembly (92,266,268,272) is mounted to the face shield (110,240) of the garment (102,236). The helmet (32,180) includes a detector (85) that is connected to and monitors the state of the button (120,134,262,264). When the button (120,134,262,264) is depressed, the detector (85) sends a signal to a controller (88) that regulates the actuation of the electrically powered assembly. The controller (88) then sets the operating state of the assembly (92,266,268,272) so that the assembly (92,266,268,272) operates in the state desired by the individual wearing the personal protection system (30,178,290) based on the depression of the control button (120,134,262,264).
