Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
a cross-legged seating apparatus consisting of: a cushion of trapezoidal cross-section, said trapezoidal cross-section comprising a horizontal base; two vertical sides of unequal length; and an angled top side connecting the unequal vertical sides; and a cushion of rectangular cross-section, said rectangular cross-section having two opposite vertical sides each of a length not greater than the length of the shorter vertical side of said trapezoidal cross-section, and further having two opposite horizontal sides each of a length substantially the same as the length of said base of said trapezoidal cross-section; and means for flexibly attaching said trapezoidal cross-sectional cushion to said rectangular cross-sectional cushion along the common edge of said base and said shorter vertical side of said trapezoidal cross-sectional cushion, and the common edge of one said vertical side and the lowermost horizontal side of said rectangular cross-sectional cushion, whereby said cross-legged seating apparatus may be used for comfortable and biomechically correct floor-based seating on any floor surface, and said rectangular cross-sectional cushion may be folded back upon the underside of said trapezoidal cross-sectional cushion to permit ready transport and storage of said cross-legged support apparatus.
Claim 2
Dependent Claim
187 words
a cross-legged seating apparatus consisting of: a cushion of trapezoidal cross-section, said trapezoidal cross-section comprising a horizontal base; two vertical sides of unequal length; and an angled top side connecting the unequal vertical sides; and a cushion of rectangular cross-section, said rectangular cross-section having two opposite vertical sides each of a length not greater than the length of the shorter vertical side of said trapezoidal cross-section, and further having two opposite horizontal sides each of a length substantially the same as the length of said base of said trapezoidal cross-section; and means for flexibly attaching said trapezoidal cross-sectional cushion to said rectangular cross-sectional cushion along the common edge of said base and said shorter vertical side of said trapezoidal cross-sectional cushion, and the common edge of one said vertical side and the lowermost horizontal side of said rectangular cross-sectional cushion, whereby said cross-legged seating apparatus may be used for comfortable and biomechically correct floor-based seating on any floor surface, and said rectangular cross-sectional cushion may be folded back upon the underside of said trapezoidal cross-sectional cushion to permit ready transport and storage of said cross-legged support apparatus.
Claim 3
Dependent Claim
25 words
The article of claim 1 wherein the means for flexibly attaching said trapezoidal cross-sectional cushion to said rectangular cross-sectional cushion is a reinforced fabric hinge.
Claim 4
Dependent Claim
15 words
The article of claim 1 wherein the cushions are made of fabric covered flexible foam.
Claim 5
Dependent Claim
