Abstract
Abstract A personal flotation device includes front and rear panels secured together to form an aesthetically appealing life vest. The panels are provided with relatively thin sheets of buoyant material of sufficient buoyancy to cause a user to remain afloat while in the water. The vest is provided with an inflatable bladder which may be readily inflated to increase the buoyancy of the flotation vest. The flotation vest is also provided with a collar through which the bladder extends and serves to cause the user to float face-up when the bladder is inflated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
251 words
A personal flotation vest device comprising: a pair of front panels and a pair of rear panels, each panel having inner and outer longitudinal edges, upper and lower edges, means securing the respective upper edges and portions of the outer longitudinal edges of a front panel and back panel together to define an armhole therebetween, means securing the inner longitudinal edges of the back panels together, and releasable closure means for releasably securing the inner longitudinal edges of the front panels together, each panel including a flexible fabric liner covering the interior surface thereof and a flexible cover covering the exterior surface thereof and secured at its periphery to the periphery of the associated fabric liner, each panel including a vertically extending sheet of buoyant material extending from adjacent the lower edge of each panel to a point adjacent the upper edge thereof and interposed between the associated liner and cover, a collar secured to said panels and including a pair of sheets of flexible fabric secured together at peripheral portions thereof, a generally U-shaped inflatable bladder formed of an elastic gas impervious material and including a pair of elongate sections and a bight portion extending between such sections said bight portion of the bladder being positioned between the sheets of said collar, each elongate section of said bladder having means thereon adjacent one longitudinal edge portion thereof attached to said closure means, and each section having means thereon adjacent its other longitudinal edge portion secured to said cover and liner.
