  • Seat having life jacket contained therein
    Patent number: 5342109
    Abstract: A life preserver-containing seat having a seat with a seat back and a seat bottom, a life jacket fitted within a cavity formed in the seat back, and a covering material having one edge joined to the seat back and extending across the life jacket. The covering material has another edge removably affixed to the seat back so as to expose the life Jacket beneath the covering material. The seat has a frame with a foam material received therewithin. The cavity is formed in the foam material. A hook-and-loop material extends around at least a portion of the periphery of the seat cavity. The covering material has a complementary hook-and-loop material removably engaging the material around the cavity.
