Abstract

A reversible orthopedic seat cushion can include a right leg support channel, a left leg support channel, a rear cutout, and a front contoured protuberance, which can allow a person sitting in the cushion to experience reduced pressure on the persons coccyx, while having support and guidance to the position of the legs. The seat cushion can also be used in a reversed position. The features of the cushion may promote a healthy sitting posture, and proper spine alignment, and may reduce or prevent back pain. Also disclosed is a method for configuring a support contour of a cushion.

Claims

1. A reversible orthopedic seat cushion comprising:

a. a right leg support channel, wherein the right leg support channel forms a convex contoured indentation, with a right lowest point line from a right rear starting point to a right front end point, wherein the right lowest point line is substantially in the middle between the right side of the cushion and the center line of the cushion, whereby the right leg support channel supports, guides, and positions the right leg of a person seated in a standard position;

b. a left leg support channel, wherein the left leg support channel forms a convex contoured indentation, with a left lowest point line from a left rear starting point to a left front end point, wherein the left lowest point line is substantially in the middle between the left side of the cushion and the center line of the cushion, whereby the left leg support channel supports, guides, and positions the left leg of the person seated in the standard position.

2. The reversible orthopedic seat cushion of claim 1, further comprising a rear-cutout, whereby a person when seated in the standard position can experience reduced pressure on the person'"'"'s coccyx.

3. The reversible orthopedic seat cushion of claim 1, further comprising a front concave contoured protuberance, whereby the seat cushion can be used in a reversed position, thereby providing a different type of support for a person sitting with the seat cushion in the reversed position.

4. The reversible orthopedic seat cushion of claim 1, wherein the lowest point lines have a substantially similar slant in a range from 0 to 100 mm per meter.

5. The reversible orthopedic seat cushion of claim 1, wherein the lowest point lines have a zero or near zero slant.

6. The reversible orthopedic seat cushion of claim 1, wherein the lowest point lines have a substantially similar slant in a range from −

50 to 0 mm per meter.

7. The reversible orthopedic seat cushion of claim 1, wherein the lowest point lines have an outward degree, so that the shortest distance of the respective starting points to the centerline, is shorter than the shortest distance of the respective ending points to the centerline.

8. The reversible orthopedic seat cushion of claim 1, wherein an inner core is manufactured using high-resilience upholstery foam.

9. The reversible orthopedic seat cushion of claim 8, wherein the inner core is made of open cell flexible polyurethane foam with a density in a range from 20 to 60 kg/m³.

10. The reversible orthopedic seat cushion of claim 1, further comprising a cushion cover.

11. The reversible orthopedic seat cushion of claim 1, wherein the cushion cover is removable.

12. A method of configuring a support contour of a cushion to promote a healthy sitting posture comprising:

defining leg support areas, which can be contoured channels to position, guide and support the legs.

13. The method of configuring a support contour of a cushion of claim 12, further comprising:

making a cut-out in the rear area of the cushion, which can ensure that there is reduced pressure on the coccyx of a person seated in the cushion.

14. The method of configuring a support contour of a cushion of claim 12, further comprising:

defining a front concave contoured protuberance, which can enable the cushion to be used in a reversed manner.

15. The method of configuring a support contour of a cushion of claim 12, wherein the leg support areas are further configured with a substantially similar slant in a range from 0 to 100 mm per meter.

16. The method of configuring a support contour of a cushion of claim 12, wherein the leg support areas are further configured with a substantially similar slant of zero or near zero.

17. The method of configuring a support contour of a cushion of claim 12, wherein an inner core is further configured using high-resilience upholstery foam.

18. The method of configuring a support contour of a cushion of claim 17, wherein the high-resilience upholstery foam is further configured with a density in a range from 20 to 60 kg/m³.

19. The method of configuring a support contour of a cushion of claim 17, wherein the cushion is further configured with a cushion cover.

20. The method of configuring a support contour of a cushion of claim 17, wherein the cushion cover is removable.
