Infant seat with opposite supporting surfaces

Claim 1

An invertible device for supporting an individual, comprising a body integrally formed as a single piece for selectively supporting the individual in a plurality of predetermined positions, said body being invertible between a first orientation and a second orientation and having a first supporting surface with a first contour which is fixed and which is sized and shaped so as to support the individual in a first position, in which the individual is supported in an upwardly facing position with its head at a higher elevation than its legs and torso, when said body is in its said first orientation, and a second supporting surface with a second contour which is fixed and which is sized and shaped so as to support the individual in a second position, in which the individual is supported in a downwardly facing position with its head at a higher elevation than its legs and torso, when said body is in its said second orientation, said first supporting surface having a first footrest portion which is substantially planar and which is located adjacent a lower end of said body, a first headrest portion which has a recess sized and shaped so as to receive the individual's head and which is located adjacent an upper end of said body, and a first seat portion which is generally concave and which is located between said first footrest portion and said first headrest portion, said first seat portion being arranged at a first inclined angle and having an upper edge and a lower edge, said first footrest portion extending downwardly from said lower edge of said first seat portion at a second inclined angle which is different from said first inclined angle, and said first headrest portion extending upwardly from said upper edge of said first seat portion at a third inclined angle which is different from said first inclined angle, and said second supporting surface having a second footrest portion which is substantially planar and which is located adjacent said lower end of said body, a second headrest portion which is substantially planar and which is located adjacent said upper end of said body, and a second seat portion which is substantially planar and which is located between said second footrest portion and said second headrest portion, said second seat portion being arranged at a fourth inclined angle and having an upper edge and a lower edge, said second footrest portion extending downwardly from said lower edge of said second seat portion at a fifth inclined angle which is different from said fourth inclined angle, and said second headrest portion extending upwardly from said upper edge of said second seat portion at a sixth inclined angle which is different from said fourth inclined angle; first engaging means for engaging an underlying support surface to immovably position said body in its said first orientation, in which said first supporting surface faces generally upwardly while said second supporting surface faces generally downwardly, whereby said first supporting surface maintains the individual in its upwardly facing position above the underlying support surface; and second engaging means for engaging the underlying support surface to immovably position said body in its said second orientation, in which said second supporting surface faces generally upwardly while said first supporting surface faces generally downwardly, whereby said second supporting surface maintains the individual in its downwardly facing position above the underlying support surface.
