Abstract
Abstract A therapeutic sling seat comprising a flexible material which is non-uniform in stiffness providing maximum contact surface area with the body of a person seated in the seat by spreading the forces away from high pressure areas using multiaxis tension forces. The seat material in tension adapts to the contour of the posterior of the seated person. By controlling the pressures on the ischial tuberosities, physical problems such as ulcers can be avoided.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
A sling seat, comprising: a plurality of flexible layers of material of non-uniform stiffness, with each layer having a top side, a bottom side, a front edge, a rear edge, and a pair of generally parallel side edges, with each of said side edges of said layers fastened together to form a pair of generally parallel side seams; at least one flexible pad located between each of said flexible layers of material; a stiffener layer located between said flexible layers containing a cutout section for accomodating the ischial tuberosities of a person seated on said seat; and means for seperately supporting each side seam to form a sling seat.
Claim 2
Dependent Claim
109 words
A sling seat, comprising: a plurality of flexible layers of material of non-uniform stiffness, with each layer having a top side, a bottom side, a front edge, a rear edge, and a pair of generally parallel side edges, with each of said side edges of said layers fastened together to form a pair of generally parallel side seams; at least one flexible pad located between each of said flexible layers of material; a stiffener layer located between said flexible layers containing a cutout section for accomodating the ischial tuberosities of a person seated on said seat; and means for seperately supporting each side seam to form a sling seat.
Claim 3
Dependent Claim
16 words
