AI Technical Summary
Existing seat cushions fail to provide targeted, four-point height adjustment of the seating surface using separately adjustable air chambers arranged at right angles, and they are not tool-free, cost-effective, or hygienic.
A seat cushion with four separate rectangular air chambers, each equipped with a tube-like non-return valve and an internal check valve, allowing for tool-free adjustment, and deflation via a pin, with an optional hygienic replaceable face mask.
Enables robust, cost-effective, and hygienic adjustment of the seating surface for orthopedic correction without requiring tools, providing targeted support for pelvic obliquity, leg length discrepancies, and spinal misalignments.
Abstract
Description
Technical field
[0001] The invention relates to orthopedic seating aids, in particular individually adjustable air seat cushions for correcting pelvic obliquity, leg length discrepancies, spinal misalignments and asymmetrical load when sitting. State of the art
[0002] Seat cushions made of foam, gel, or with a uniform air chamber, as well as multi-chambered wheelchair cushions, which primarily serve to distribute pressure, are well-known. None of these solutions allows for targeted, four-point height adjustment of the seat surface using separately adjustable air chambers arranged at right angles. Object of the invention
[0003] The task is to provide a simply constructed, cost-effective and robust seat cushion that allows for an orthopedically effective adjustment of the seating surface, can be operated without tools or pumps and is hygienic to use. Solution to the task
[0004] The solution involves a seat cushion with four completely separate rectangular air chambers, each with a tube-like non-return valve and an internal check valve. Deflation is achieved by inserting a pin. The mouthpiece can be fitted with a hygienic, replaceable face mask.
Claims
[1] Seat cushion with four airtight, rectangular air chambers formed by a cross-shaped, right-angled separating structure, each air chamber having a separate, tube-like valve with an internal non-return element that allows unidirectional air inflation and controlled deflation by inserting a pin, and wherein the valve may optionally be fitted with an interchangeable hygienic mouth guard. [2] Seat cushion according to claim 1, wherein the air chambers are each assigned to a front and rear as well as left and right quadrant of the seat surface. [3] Seat cushion according to claim 1 or 2, made of weldable foil materials. [4] Seat cushion according to one of the preceding claims, wherein the filling is done manually. [5] Seat cushion according to one of the preceding claims, with optional textile cover or non-slip underside. [6] Seat cushion according to one of the preceding claims, with optional orientation aids or markings. [7] Seat cushion according to one of the preceding claims, wherein the non-return element is designed as a flap, membrane or functionally equivalent component.
