Personal floatation device
First Claim
1. A floatation panel for a personal floatation device, said floatation panel comprising:
- a first panel of fabric having a first surface area and a peripheral edge;
a second panel of fabric having a second surface area and a peripheral edge;
a panel of buoyant material, the panel of buoyant material comprising an outer surface, an inner surface, a peripheral edge, and a plurality of slits that pierce the panel of buoyant material from the outer surface to the inner surface, wherein the plurality of slits form a plurality of ribs between the slits;
wherein the panel of buoyant material is loosely encased between the first panel of fabric and the second panel of fabric, wherein the first panel of fabric is disposed to cover the outer surface of the panel of buoyant material, and wherein the second panel of fabric is disposed to cover the inner surface.

Abstract
Various exemplary embodiments of the present invention would provide a back floatation panel comprising an inner panel and an outer panel. The inner panel and the outer panel would be joined to each other in such a way as to allow “bellowed” expansion of a space, or a “sleeve,” in between the inner and outer panels. The bellowed expansion space between the inner and outer panels would be adapted for accommodating, for example, a hydration bladder and/or an insert of high density polyethylene (“HDPE”) plastic for protecting the wearer'"'"'s back. The inner and outer panels would be joined in such a way as to provide a pathway through which a hydration tube can be inserted. Various exemplary embodiments of the present invention would provide differentially cut fabric panels for covering buoyancy panels. An outer fabric panel, comprising an outer panel surface area, would be used to cover an outer surface of a buoyancy panel. An inner fabric panel, comprising an inner panel surface area, would be used to cover an inner surface of the buoyancy panel. In various exemplary embodiments, the outer panel surface area would be greater than inner panel surface area. That is, the outer panel would comprise a greater number of square inches of fabric than will the inner panel. Various embodiments of the present invention would also provide slit buoyancy panels to allow the buoyancy panels to contour over three-dimensional shapes. Various exemplary embodiments of the present invention would provide a personal floatation device with a belt pivotally connected to a back panel of the personal floatation device. Various embodiments of the present invention would provide front floatation panels for a personal floatation device comprising an upper buoyancy panel, a lower buoyancy panel, and a baffle system separating the upper buoyancy panel from the lower buoyancy panel.
