Patent ID: 8578525

Claim:
A sleeping bag for receiving and providing selective concurrent coverage and exposure of two body areas and segments of a body of a human user, comprising: an elongate sleeping bag shell comprising a flexible top cover panel and a flexible bottom panel, each having a head end, a foot end, and laterally opposed sides defining an interior space therebetween sized and shaped to receive, cover, and enclose the body of a human user from at least a neck of the body of the user to toes of the body of the user in said interior space; a transverse waist opening and a transverse ankle opening in said top cover panel disposed in longitudinally spaced apart locations between said head end and said foot end thereof extending transversely substantially across the width of said top cover panel terminating adjacent to said laterally opposed sides thereof, each extending entirely through only said top cover panel and defined by a pair of adjacent separable edges of said top cover panel disposed in opposed facing relation; and closure means on each of said adjacent separable edges of each of said body segment ingress/egress openings in said top cover panel for selectively joining said adjacent separable edges together to close said openings and separating said adjacent separable edges to open said openings; said transverse waist opening disposed in a plane at a location adapted to correspond generally to a transverse plane extending through a waist area of the body of the user, which in an open condition enables ingress of a lower body segment below the waist area including upper leg segments, knee joints, ankle joints, and foot segments of the body, into said interior space so as to be capable of being covered by said top cover panel and, concurrently therewith, egress of an upper body segment above the waist area including a torso segment, arm segments, neck, and head of the body out of said interior space so as to be capable of being uncovered by said top cover panel, and vice versa, and said transverse ankle opening disposed in parallel longitudinally spaced apart relation to said waist opening in a plane at a location adapted to correspond generally to a transverse plane extending through the ankle joints of the body of the user, which in an open condition enables selective ingress of either one or both of the foot segments into said interior space so as to be capable of being covered by said top cover panel or egress of either one or both of the foot segments out of said interior space so as to be capable of being uncovered by said top cover panel.
