A head stabilizing system is provided. The head stabilizing system is intended to minimize loads on the head and the neck, some of which may be injurious or even fatal, by generating a reaction force that substantially opposes a force acting on the head and generated by rapid deceleration of a vehicle or a crash impact. The head stabilizing system includes a helmet, a connection structure, and at least one resisting member. A mounting element is provided to be mounted onto the helmet to connect to the at least one resisting member. The mounting element is preferably attached to the helmet by an adhesive. The resisting member generates a reaction force that opposes the crash impact force, yielding a reduced net force on the head. This reaction force can be generated as a function of position, velocity or acceleration. The resisting member may include a tether, a dashpot, or a dashpot containing a controllable rheological fluid. The viscosity of the controllable rheological fluid can be automatically adjusted in response to changes in status of a vehicle or it's occupant.

The weight of the canopy upon opening is borne by a pair of side gas or spring struts (24).

A head and neck restraint system includes a headpiece, a saddle, and tensioners connecting the headpiece to the saddle. The headpiece resides on top of a crew member's head and the saddle includes a saddle strap residing under the crew member's buttocks. The tensioners are pneumatic muscles which contract when a flow of gas is provided by gas generators. The gas generators are triggered by a G-sensor or by the initiation of a predetermined event. Triggering signals pass through a manifold from an ejection seat, aircraft, or vehicle. Contraction of the pneumatic muscles pulls the headpiece toward the saddle, thereby restraining the head, neck, and spine. The system is worn as an undergarment or incorporated into a garment. A manual adjustment provides head support during flight. The system is particularly useful for preventing head and neck injuries during ejection from or crash of an aircraft or vehicle

A pressure regulation device is provided, in particular for an oxygen emergency supply system in an aircraft.

The present invention enables functional testing nearly all aircrew equipment including a COMBAT EDGE (combined advance technology enhanced design “G” ensemble) system of components which include a mask, a G-suit, communication systems, and a goggle. The present invention includes a gas system which includes an input filter (101), a first compressor (102) comprising at least one blower, preferably three blowers connected in series, a second compressor (103), a first flow sensor (106), a second flow sensor (107), a first flow valve (104), a second flow valve (105), a regulator (108), a first pressure sensor (112), a second pressure sensor (113), a first pressure valve (110), a second pressure valve (114), and a controller. The inlet filter (101) is designed to accept a chemical filter. The second compressor (103) produces a lower flow at a higher pressure than the first compressor (102). This combination works particularly well when inflating the G-suit because when the G-suit inflates, initially there is a large change in volume without much change in pressure, and then, as the G-suit fills out and becomes firm, the chance in volume slows down and the rate of the pressure increases. The present invention includes a digital indicator. A method of operating the tester and the gas system are also disclosed. The present invention includes a normal breathing test, a preflight test, a G-suit leak test and two dynamic flow leak tests. The communication system test and goggle test are further included.

The invention relates to an oxygen breathing device, in particular for cockpit crew member of an aircraft, comprising a pressurized oxygen source for storing pressurized oxygen, an oxygen mask, adapted to fit to nose and mouth of a person to be supplied with oxygen from the pressurized oxygen source, an oxygen supply line connecting the pressurized oxygen source with the oxygen mask, a pressure regulator/safety valve coupled in the oxygen supply line to selectively open or shut off oxygen flow from the pressurized oxygen source to the oxygen mask and/or to control pressure of said oxygen supplied to the oxygen mask. According to the invention, such oxygen breathing device is improved by having a pneumatic seal adapted to pneumatically seal the pressurized oxygen source in a non-use condition, an opening device adapted to open the pneumatic seal in case of an emergency situation requiring oxygen supply to the person, a change over valve adapted to selectively supply oxygen from the pressurized oxygen source or pressurized air from a pressurized air source to the oxygen mask.

A head and neck restraint device controls the motion of the head and forces exerted upon the neck of a seated occupant in a decelerating vehicle. A body defines a collar, right and left legs and right and left wings. The collar is tethered to the helmet. Each leg has belt interaction surfaces that provide a friction action on the shoulder straps. Left and right extensions or wings residing under the shoulder strap rearward of the legs provide a restriction of rotation of the body and thus a binding action on the shoulder straps. A cantilever action is induced in generally forward impact by the tethers pulling on the collar of the body and the binding action on the shoulder straps reducing the forward motion of the body. The present restraint device does not attach to the structure of the vehicle, allows travel thereof with respect to the seated occupant, yet controls the motion of the occupant's head in order to substantially reduce neck loads on the occupant. Moreover present restraint device is not in contact with the occupant during normal operation and thus does not induce discomfort or fatigue. Under general forward impact conditions, the occupant's head motion is controlled with respect to the torso, yet the device will restrictively move with the driver's head and torso along shoulder straps of a seat harness of the vehicle.

An oxygen supply device, preferably a pilot oxygen supply device, has an oxygen source and at least one oxygen mask. A breathing regulator is arranged between the oxygen source and the oxygen mask. An oxygen sensor is arranged downstream of this breathing regulator.
