Flotation jacket

Claim 2

A flotation jacket composed essentially of resilient foam plastics material comprising a permanently contoured member for conforming to the contour of the back, rib cage and shoulders of the human body, said jacket having its marginal edges rounded and having a smooth continuous outer surface and a grooved interior surface, said interior surface being provided with inwardly opening intersecting grooves therein, certain of which are deformed for being relatively narrow along concaved portions of said interior surface and certain other of which are relatively wide along flatter portions thereof to promote conformity to natural body curves, the grooves along the front and back portions of the jacket opening downwardly toward the lower edge of the jacket to promote drainage, and closure means for the jacket at the front of the jacket.

Claim 3

A flotation jacket as defined in claim 1, and the grooved interior surface having a waffle pattern.

Claim 4

A flotation jacket as defined in claim 1, and said jacket being open at its opposite sides, and said closure means comprising at least one strap encircling the jacket horizontally and across its open sides and having quick release fastener means at the front of the jacket.

Claim 5

A flotation jacket as defined in claim 1, and said jacket having a bottom edge and having a region of increased wall thickness near the bottom edge compared to the wall thickness of the remainder of the jacket to increase the buoyancy of the jacket near its bottom.

Claim 6

A flotation jacket as defined in claim 1, and said jacket having an outer thin non-cellular substantially smooth skin thereon.

Claim 7

A flotation jacket as defined in claim 5, and said foam plastics material being polyvinylchloride and said skin comprising a vinyl skin.

Claim 8

The flotation jacket defined in claim 1 wherein said grooves intersect each other for defining a waffled interior surfaces, said grooves along the surface of said back wall being straight and criss-crossed with respect to each other and extending angularly with respect to the bottom edge of said back wall.

Claim 9

A flotation jacket comprising a unitary molded plastic body having a back wall, a pair of opposed front torso walls, curved shoulder section for respectively passing over the shoulders of a person, the ends of said curved shoulder sections being connected to the upper edge portions of said back wall and connected respectively to the upper edge portion of said front torso walls, a pair of generally parallel straps encircling said front torso walls and said back wall, loops on said front torso walls and said back wall for supporting said straps, said straps terminating outwardly adjacent to the opposed edges of said front torso walls, buckles on the ends of said straps for coupling and releasing said straps, the outer edges of said back wall, said shoulder sections and said front torso walls being rounded, the inner surfaces of said back wall, said shoulder sections and said front torso wall being provided with intersecting grooves for defining waffled surfaces, the grooves defining the inner surfaces of said shoulder sections being more narrow than the grooves along said front torso walls and said back wall.

Claim 10

A flotation jacket comprising a unitary molded plastic body having a back wall, a pair of opposed front torso walls, curved shoulder section for respectively passing over the shoulders of a person, the ends of said curved shoulder sections being connected to the upper edge portions of said back wall and connected respectively to the upper edge portion of said front torso walls, a pair of generally parallel straps encircling said front torso walls and said back wall, loops on said front torso walls and said back wall for supporting said straps, said straps terminating outwardly adjacent to the opposed edges of said front torso walls, buckles on the ends of said straps for coupling and releasing said straps, the outer edges of said back wall, said shoulder sections and said front torso walls being rounded, the inner surfaces of said back wall, said shoulder sections and said front torso wall being provided with intersecting grooves for defining waffled surfaces, the grooves defining the inner surfaces of said shoulder sections being more narrow than the grooves along said front torso walls and said back wall.

Claim 11

The flotation jacket defined in claim 8 wherein the side edges of said front torso walls are respectfully integrally joined to the side edges of said back wall.

Claim 12

The flotation jacket defined in claim 8 wherein the outer surface of said back wall and torso walls are smooth and said grooves are V-shaped and terminate spaced inwardly of the smooth outer surfaces of said back wall and said torso walls.

Claim 13

A flotation jacket comprising a jacket body molded as a unit from foam plastics material and being permanently contoured in the molding process to fit a human body of a particular size, the jacket body having shoulder covering portions, a back wall and side walls and also having a divided front wall, the jacket body having arm openings above said side walls, the jacket body having marginal edges which are rounded for comfort, the entire interior surface of the jacket body being deeply grooved with a waffle pattern to promote drainage and to promote conformity to body contours, the jacket body having an exterior skin of smooth non-cellular plastics material integrally bonded thereon, and front closure means for the jacket including straps which encircle the front, side and back walls of the jacket body.

Claim 14

A flotation jacket comprising a jacket body molded as a unit from foam plastics material and being permanently contoured in the molding process to fit a human body of a particular size, the jacket body having shoulder covering portions, a back wall and side walls and also having a divided front wall, the jacket body having arm openings above said side walls, the jacket body having marginal edges which are rounded for comfort, the entire interior surface of the jacket body being deeply grooved with a waffle pattern to promote drainage and to promote conformity to body contours, the jacket body having an exterior skin of smooth non-cellular plastics material integrally bonded thereon, and front closure means for the jacket including straps which encircle the front, side and back walls of the jacket body.
