Abstract
The invention relates to a combination of a helmet or a protective mask and a respirator that can function under ram pressure. The helmet's chin arch (1) contains a face element (4), a filter (3) and inhalation and exhalation valves (5,6). The air can, for instance, flow through the apertures (2) in the chin arch (1) to the respirator. The face element (4) can be moved by means of a lever (11) in accordance with the pressure caused by the air stream.
Claims18
An assembly for protecting a use's head comprising a helmet and a respirator for purifying of the air to be breathed by the user, said helmet comprising:
- a wall structure having a front opening for forward viewing by a user's face;
- a shield covering said opening;
- an protective arch engaging said wall structure;
- and
- an air inlet openings disposed in said helmet through which air passes through, said respirator being joined to said arch, said respirator comprising:
- a filter situated between said air inlet and a user's face;
- inhalation valve between said filter and said user's face;
- a face element movable from a first position in which it is in contact with the face of a user and a second position in which it is not in contact from the user's face;
- and
- an exhalation valve located adjacent said face element.
A method for purifying air through a helmet by a respirator situated therein, said helmet having a wall structure with a front opening for forward viewing by a user's face, a shield covering said opening, a protective arch engaging said wall structure, and an air inlet openings disposed in said helmet through which air passes through, said respirator being joined to said arch, said respirator comprising a filter situated between said air inlet and a user's face, an inhalation valve between said filter and said user's face, a face element movable from a first position in which it is in contact with the face of a user and a second position in which it is not in contact from the user's face, and an exhalation valve located adjacent said face element, said method comprising the steps of:
- forwarding said outside air through said helmet via said air inlet,
- guiding and filtering said air through the filter for purifying said air before the user breaths the same,
- regulating the flow of air to the face element by moving the face element of the respirator between the position in which the face element is in contact with the user's face and the position in which the face element is not in contact with the face.
An assembly comprising a mask for protecting a user's head and a respirator for purifying the air to be breathed by the user, the mask comprising:
- a wall structure having a front opening for forward viewing by a user's face;
- a shield covering said opening;
- and
- an protective arch engaging said wall structure;
- said respirator comprising:
- a filter situated between said mask and said user's face;
- inhalation and exhalation valves located at the rear of said filter;
- a face element movable from a first position in which it is in contact with the face of a user and a second position in which it is not in contact from the user's face.
