This disclosure additionally includes a description of a seat cushion (FIGS. 1 to 5), which is described and claimed in PCT Patent Application No. PCT/US2013/024008, entitled “SEAT CUSHION WITH FLEXIBLE CONTOURING,” filed Jan. 31, 2013, which claims the benefit of U.S. Provisional Application No. 61/593,155, entitled “SEAT CUSHION WITH FLEXIBLE CONTOURING,” filed Jan. 31, 2012, the entire disclosures of which are hereby incorporated herein by reference.
In several embodiments of the present disclosure, a foot positioner is provided that supports the foot from the ankle. For example, the foot positioner can support the foot of a user relative to a support surface (hereinafter “bed surface”) of the bed or piece of furniture in which foot positioner is installed. Embodiments of the positioner can provide benefits such as relieving pressure and/or shear forces exerted on portions of the foot such as the heel, providing lateral support to reduce external rotation of the foot and leg, and/or providing support at the bottom of the foot to reduce planter flexion.
a top surface on a top side of the body;
a bottom surface on a bottom side of the body and configured to face a support surface, the bottom surface comprising at least one support configured to offset the bottom surface from the support surface an amount sufficient to allow airflow between the bottom surface and the support surface;
a plurality of holes, each hole in the plurality passing through the top surface, extending through the body, and passing through the bottom surface; and
a plurality of troughs disposed on the bottom surface and embedded into the body, the plurality of troughs disposed between the at least one support to decrease surface tension on the bottom surface near the plurality of troughs.
2. The seat cushion of claim 1 wherein the at least one support further comprises:
a first subset of the at least one support dimensioned to contact the support surface when the seat cushion is in an unloaded configuration;
a second subset of the at least one support dimensioned to not contact the support surface in the unloaded configuration;
wherein in a loaded configuration when a weight of a user is placed on the top surface at least some of the supports in the second subset of supports contact the support surface; and
wherein a number of the supports in the second subset of supports that contact the support surface in the loaded configuration depends on a specific weight and body contour of the user.
3. The seat cushion of claim 2, wherein the supports corresponding to the second subset are shortest underneath an area of the seat cushion for receiving ischial tuberosities of the user and increase in height as support placement on the bottom surface moves away from the area of the seat cushion for receiving ischial tuberosities of the user.
4. The cushion of claim 2, wherein the seat cushion deforms primarily by bending as a load is applied in the loaded configuration.
5. The cushion of claim 2, wherein the top surface further comprises a contour configured to match a generic anatomical shape of a seated user.
6. The cushion of claim 5, wherein the contour further comprises a recessed area configured to receive a pelvis and coccyx of the seated user and elevated components to support and orient thighs and hips of the seated user.
7. The seat cushion of claim 1 wherein the at least one support further comprises:
a first subset of the at least one support dimensioned to contact the support surface when the cushion is in an unloaded configuration;
a second subset of the at least one support dimensioned to not contact the support surface in the unloaded configuration, the second subset of the at least one support having an unloaded height being a sum of the distance between a bottom of each support of the second subset and the support surface in the unloaded configuration;
wherein in a loaded configuration when a weight of a user is placed on the top surface the unloaded height is greater than a loaded height being a sum of the distance between a bottom of each support of the second subset and the support surface in the loaded configuration;
wherein a difference between the unloaded height and the loaded height depends on a specific weight and body contour of the user.
8. The seat cushion of claim 7, wherein the supports corresponding to the second subset are shortest underneath an area of the seat cushion for receiving ischial tuberosities of the user and increase in height as support placement on the body moves away from an area of the seat cushion for receiving ischial tuberosities of the user.
9. The seat cushion of claim 7, wherein the cushion deforms primarily by bending as a load is applied in the loaded configuration.
10. The seat cushion of claim 7, wherein the body further comprises a contour configured to match a generic anatomical shape of a seated user.
11. The seat cushion of claim 10, wherein the contour further comprises a recessed area configured to receive a pelvis and coccyx of the seated user and elevated components to support and orient thighs and hips of the seated user.
12. The seat cushion of claim 1, wherein the troughs are rounded.
13. The cushion of claim 1, wherein the troughs are positioned in a row and column pattern.
14. The cushion of claim 1, wherein the troughs are positioned only in locations of maximum surface tension.
15. The cushion of claim 1, wherein the troughs extend over the entirety of the bottom surface.
16. The cushion of claim 1, wherein the embedded plurality of troughs form a plurality of depressions in the body.
