| A facemask incorporating breathing equipment for use with a flying helmet (2) comprises a rigid outer shell (4) in which a flexible face-piece (3) is housed whose periphery makes an airtight seal with the pilot's face (1). The face-piece (3) includes an inhalatory valve (11) and an expiratory vane (9) and the rigid shell (4) is attached to the helmet (2) by a harness (5) which keeps the shell (4) at a fixed distance from the helmet (2). Inflatable means (15, 20) are provided between the shell (4) which are inflated to press the periphery (14) of the face-piece towards the pilot's face when the pressure of breathable gas supplied to the interior of the mask and to said inflatable means increases above that required for normal breathing. Alternatively, the face-piece (3) can include extendable means in the form of a re-entrant section (30, 34, 35) or bellows section (36) which extends in a direction towards the pilot's face when the pressure of the breathable gas supplied to the interior of the face-piece (3) increases above that required for normal breathing. | ||||||
| 103 | Safety helmets | US828909 | 1992-01-24 | US5237707A | 1993-08-24 | Robert Lowrie |
| Safety helmets, totally encasing the wearer's head and incorporate breathing apparatus supplying air to and exhausting air from an isolated volume within the helmet, are well known. The isolated volume is defined by a viewing panel, an annular seal and the face of the wearer.There is a problem in fitting and removing such a helmet which has been solved in prior art constructions by making the helmet from two shell halves, hinged together at the crown of the helmet.The invention proposes a one-piece helmet shell, which has a front to rear dimension more the one and a half times that of the wearer's head, and providing a pad so supported that it can be displaced to the rear regions of the helmet, to facilitate fitting and removal of the helmet, and with the helmet fitted pushes the head of the wearer into pressure contact with the annular seal. | ||||||
| 104 | Personnel headgear enabling free breathing of ambient air or selective breathing from various sources | US219302 | 1988-07-14 | US5078130A | 1992-01-07 | Lucien F. A. Van Oosten; Stanley A. Bonner |
| Protective headgear with a face shield which can be tilted up out of the way, and which when tilted downwardly can be placed in a standby position enabling free breathing of ambient air through a gap between a helmet and the face shield, and can be pressed back to create a seal to require breathing from a controlled source. A selector is mounted on the face shield to enable the wearer to make a quick and effective selection of breathing modes. A face seal can be mounted to the inside of the face shield to form an oro-nasal dam around the nose and mouth of the wearer to provide another seal, and a reduced plenum volume. | ||||||
| 105 | Air cushion helmet support and ventilation system with air pressure regulator | US523449 | 1990-05-14 | US5050240A | 1991-09-24 | James L. Sayre |
| An air cushioned safety and/or display helmet. A thin cushion of air between the wearer's head and the inside of the helmet supports the helmet and distributes the helmet's weight evenly thus preventing development of pressure points and corresponding wearer fatigue. When used in a high performance environment which exposes the user to g forces, such as fighter aircraft, an air regulator controls the air pressure of the air cushion in response to these forces to maintain helmet position and comfort. Air contained in the air cushion can also be used to demist the helmet visor and display optics, can be directed past the head to provide heating or cooling of the head, or can do both at one time. | ||||||
| 106 | Clean room helmet system | US219220 | 1988-07-15 | US5046492A | 1991-09-10 | Wyman H. Stackhouse; Ian M. Williamson |
| There is described an improved clean room helmet system including a helmet having an inlet port and an exhaust port. Connected to the inlet port is a portable and mobile pressure filtering system for suppling filtered air to the helmet. A separate portable and mobile vacuum filtering system is connected to the outlet port on the helmet for exhausting and filtering all air removed from the interior of said helmet before exhausting the air into the atmosphere. All air fed to the helmet is filtered and all air exhausted from the helmet is filtered thereby protecting the user from breathing contaminated air. The system also protects those persons in the environment from air being exhausted from the helmet into the environment. A deflector located within the helmet prevents pressurized air entering the inlet port from being fed directly to the exhaust port located on the helmet. | ||||||
