Cold-proof water-proof garment

Claim 3

Means for facilitating rotation of a man wearing a full body suit with fluid buoyancy from a face-down prone position to a face-up prone position comprising a full body suit having a first buoyancy chamber internally of the suit adequate to float the wearer in a prone position and a second buoyancy chamber internally of the suit asymmetrical over the chest of the wearer, whereby inflation of said second buoyancy chamber provides asymmetrical buoyancy within the body suit over the chest of the wearer to create additional space within the suit asymmetrically over the chest of the wearer for the buoyant fluid in said first chamber to collect to thus rotate the wearer from a face-down prone position to a position from which the wearer can complete the rotation to a face-up prone position.

Claim 4

Means for facilitating rotation of a man wearing a full body suit with fluid buoyancy from a face-down prone position to a face-up prone position comprising a full body suit having a first buoyancy chamber internally of the suit adequate to float the wearer in a prone position and a second buoyancy chamber internally of the suit asymmetrical over the chest of the wearer, whereby inflation of said second buoyancy chamber provides asymmetrical buoyancy within the body suit over the chest of the wearer to create additional space within the suit asymmetrically over the chest of the wearer for the buoyant fluid in said first chamber to collect to thus rotate the wearer from a face-down prone position to a position from which the wearer can complete the rotation to a face-up prone position.

Claim 5

A cold-proof water-proof garment with substantially water-proof wristbands and a selectively enlarged neck opening comprising: an outer layer made of a relatively non-stretchable water-proof material; an inner layer for temperature insulation and buoyancy, said inner layer including one of (a) a buoyant foam lining for said outer layer and (b) a temperature insulating inner suit separable from said outer layer to form a first buoyancy chamber between said layers; and a second buoyancy chamber carried by said outer layer internally thereof in the area of said neck opening and laterally asymmetrical with respect to the chest area, said second chamber being selectively inflatable inwardly of said outer layer to urge the internal surface of said second chamber toward the neck of the wearer to thereby provide a substantially water-proof seal around the neck of the wearer and to facilitate rotation of the wearer to a face-up position by creating additional space within the suit asymmetrically over the chest of the wearer for the buoyancy fluid to collect.

Claim 6

A cold-proof water-proof garment with substantially water-proof wristbands and a selectively enlarged neck opening comprising: an outer layer made of a relatively non-stretchable water-proof material; an inner layer for temperature insulation and buoyancy, said inner layer including one of (a) a buoyant foam lining for said outer layer and (b) a temperature insulating inner suit separable from said outer layer to form a first buoyancy chamber between said layers; and a second buoyancy chamber carried by said outer layer internally thereof in the area of said neck opening and laterally asymmetrical with respect to the chest area, said second chamber being selectively inflatable inwardly of said outer layer to urge the internal surface of said second chamber toward the neck of the wearer to thereby provide a substantially water-proof seal around the neck of the wearer and to facilitate rotation of the wearer to a face-up position by creating additional space within the suit asymmetrically over the chest of the wearer for the buoyancy fluid to collect.

Claim 7

The garment of claim 3 wherein said garment includes a hood having a face opening and a third buoyancy chamber internally thereof in the rear of said hood so that inflation of said third buoyancy chamber provides additional buoyancy at the wearer's head and urges the hood backward on the head of the wearer to provide a substantially water-proof seal around the face of the wearer.

Claim 8

The garment of claim 4, wherein said second and third buoyancy chambers are in fluid communication.

Claim 9

The garment of claim 5 wherein said second chamber includes a band completely around said neck opening, said neck band being opened in the front of the garment at an angle to a radial to thereby provide overlapping flaps which are urged together by the inflation of said second chamber.

Claim 10

The garment of claim 6 wherein the front opening in said neck band extends downwardly in the front of said garment; and wherein said second chamber includes overlapping flaps which are urged together by the inflation of said second chamber.

Claim 11

The garment of claim 3 wherein said second chamber includes a neck band and a chest portion interrupted to form an opening in said neck band and in the front of the garment with overlapping flaps urged together to close the opening by the inflation of said second chamber.

Claim 12

The garment of claim 8 including a source of compressed fluid carried externally of said outer layer for inflating said second chamber.

Claim 13

The garment of claim 3 including a source of compressed fluid carried externally of said outer layer for inflating said second chamber.
