Orthopedic seating wedge with ventilation channels

Abstract

The invention consists in an orthopedic seating wedge with ventilation channels. The wedge is manufactured in a CNC machining process from a chemically cross-linked polyethylene foam with density from 40 to 50 kg/m3. The orthopedic wedge, as illustrated on FIG. 1, has a profiled body (6), with a depression in the rear (3) to maintain a straight posture of the user as well as vertical (5) and horizontal (2) ventilation channels allowing skin air access, protrusions (4) to improve blood circulation in the skin tissue, as well an indentation in the tailbone area (1) in order to relieve the lower back and enhance sitting comfort. Appropriate material hardness prevents deformations resulting from user weight, enables it to be used on various surfaces as well as allows the wedge to have the above mentioned features while ensuring adequate sitting comfort.
