Description

Sept. 19, 1961 c. RICH PRESSURE SUIT Filed may 1o, 1955 Inventor CARL R/cH by" QLQQMNQ Filed May 10, 1955, Ser. No. 507,405 4 Claims. (Cl. 2-2.1)

'This invention relates to a pressure suit for aircraft pilots.

It is the main object of the invention to provide a pressure suit which is air or gas permeable.

Other objects of the invention will be appreciated by a study of the following specification taken in conjunction with the accompanying drawings.

In the drawings:

FIGURE l is a view of a pressure suit of the invention as worn by a pilot;

FIGURE 2 is a diagrammatic plan section of the suit of FIGURE 1 in the chest region illustrating the contracting action thereof in increasing pressure upon the wearer;

FIGURE 3 is a sectional view of the air permeable materials from which the suit of FIGURE l is formed.

Referring to the drawings, the pressure suit of the invention preferably comprises a contractible body covering 10, a helmet 11, gloves 12, and boots 13.

The covering is formed of an air permeable mate rial 14 shown in section in FIGURE 3 having an outer layer preferably formed of closely knitted relatively ne enamel-insulated copper wire cloth 15 separated from an inner cotton or other suitable textile cloth 16 by an inisulating material 17 such as batting formed of line glass bers.

Sleeves 1-8 are fastened relatively tightly about the wearers arms by the slide fasteners v19 and are laced as at 20 to a shoulder fitting 21 on each side suitably reinforced with leather sheeting 22 or the like. The covering 10 is separable on substantially vertical spaced apart

lines

24 and 25 extending from shoulder to toe down the front of the body and is suitably reinforced by reinforcing

strips

25 and 26 to support

lacings

27 and 28 whereby in the upper regions of the suit so formed a front panel portion 29 is fastened to a back panel portion 30 as shown in FIGURE 2.

Tensioning electrical solenoid devices 31 having a conventional solenoid or coil part 32 adapted to draw thereinto the rod or core 33 anchored to anchorage fitting 34, are mounted on the

reinforcing strips

25 and 26. The solenoid devices 31 are connected electrically in parallel through junction box 31a and cable 31b to a suitable source of electrical power including a rheostat (not shown) whereby the energization of the solenoids can be controlled to apply predetermined tensioning represented by arrows Y and effect control of pressure or tensioning upon the body of the wearer. As shown in FIGURE l, the solenoid devices may be covered by a pliable pouch 35 to protect the mechanism thereof.

The helmet 11 may embody earphones 36 and a microphone 37 connectable by cable 38 to a communication system (not shown). Note that the boots 13 terminating at 39 are also tensionable and are separable upon removal of

lacings

27 and 28.

A metal fabric formed of knitted wire wherein each wire carries an insulating coating forms a part of this invention. It is intended that a plurality of individual wires of such fabric may be connected electrically in parallel to serve as an electrical conductor having resistance to current iiow whereby the fabric may be heated. Also the metal fabric herein as compared with a textile fabric may present a greater mass for absorption of nuclear radiation. The gloves 12 may be formed of the metal fabric of the invention without additional insulatlefed Sete., Patent' 0 V'ing layers of material. Because the fabric is "ice" knitted and is of metal it embodies a limited characteristic of stretchability adapted to confine the ilesh at low atmospheric pressures. Accordingly, special tensioning devices need not necessarily be employed in regions of the arms and hands of the wearer.

What I claim as my invention is:

1. A pressure suit adapted to compensate for changes in atmospheric pressure upon the body of a wearer and comprising in combination: metal wire fabric gas perm@ able pliable panels of limited interstitial stretchability formed to enclose the human body; electrical tensioning means attached to portions of adjacent panels; and electrical conducting means for providing electrical energization of said tensioning means whereby said panels are tensioned to apply a predetermined pressure to the body of the wearer while enabling the skin of the body to breathe through said panels at substantially atmospheric pressure.

2. A pressure suit adapted to compensate for changes in atmospheric pressure upon the body of a wearer and comprising in combination: knitted insulated metal wire fabric gas permeable pliable panels of limited interstitial stretchability formed to enclose the human body, said insulated Wire constituting an electrical conductor; an electrical circuit for supplying electrical energy to said conductor whereby heat may be generated; electrical solenoid tensioning means having core parts attached to an edge of one of said panels and coil parts attached to an edge of an adjacent panel; and electrical conducting means for providing electrical energization of said tensioning means whereby said panels are tensioned to apply a pre determined pressure to the body of the wearer while enabling the skin of the body to breathe through said panels at substantially atmospheric pressure.

3. A pressure suit adapted to compensate for changes in atmospheric pressure upon the body of a wearer and comprising in combination: gas permeable pliable panels of limited interstitial stretchability formed to envelope the torso arms and legs of the human body; a plurality of electrical solenoid devices each having a core part attached to an edge of one of said panels and a coil part attached to an edge of an adjacent panel, said devices being adapted for tensioning said panels; and electrical conducting means for providing electrical energization of said devices whereby said panels are tensioned about the body of the wearer while enabling the skin of the body to breathe through said panels at substantially atmospheric pressure.

4. A suit adapted to confine the esh of the body of the wearer under a condition of low atmospheric pressure and comprising in combination: a plurality of flexible gas permeable panels formed of knitted metal wire of limited interstitial stretchability and adapted to enclose the human body; means connecting certain of said panels to denne an enclosing suit for a wearers body enabling the skin of the body to breathe at atmospheric pressure through said panels; electrical solenoid tensioning means having a core part thereof attached to an edge of one of said panels and the coil part thereof attached to an adjacent panel; and electrical conducting means for providing electrical energization of said tensioning means whereby said panels are tensioned to restrict the esh of the body to substantially maintain the internal pressures therein under a condition of lesser external atmospheric pressure providing normal body evaporation function under abnormally low pressure conditions.
