C-Shaped Coccyx, Sacrum, And Lumbar Seat Cushion

Abstract

Apparatus, systems, and methods are disclosed involving a seat cushion configured as a partially-open annular ring, including a circular hollow space in a center of the ring, and a radial-arc-shaped opening in the ring forming a trapezium-shaped hollow space. Both the circular hollow space and the trapezium-shaped hollow space are located corresponding to the user's spine and coccyx, with the trapezium-shaped hollow space located on a rear portion of the cushion. The circular hollow space frees the perineal region from external compression by avoiding having any portion of the center of the seat cushion pressing against it, and the trapezium-shaped hollow space frees the sacrococcygeal region from external compression by not having any portion of partially-open annular ring of the seat cushion pressing against it.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is related to, is a non-provisional application of, and claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 010,529 (“the '529 application”), filed 2020 Apr. 15, titled “C Shaped Coccyx, Sacrum, And Lumbar Cushion,” which is incorporated by reference herein in its entirety for all purposes.BACKGROUND OF THE INVENTION[0002]Embodiments of the present invention generally relate to apparatus, systems, and methods for cushioning a seat of a person who is subject to experiencing lower back pain when seated. More specifically, the present invention relates to apparatus, systems, and methods for preventing, reducing, and / or alleviating lower back pain of a seated person, comprising a seat cushion designed and adapted to reduce pressure applied to the seated person's sacrum and coccyx when the seated person's body weight presses down against a supporting surface on which the seated person is sitting.[0003]A comm...

AI Technical Summary

Benefits of technology

The invention relates to a seat cushion that prevents pressure on the perineal and sacrococcygeal regions of a seated person, reducing pain. The seat cushion has a partially-open annular ring of cushioning material that defines a hollow circular space and a hollow space along a radial arc portion missing from a rear of the ring. The hollow circular space connects to the hollow space along the radial arc portion. The seat cushion is positioned under the seated person with the hollow circular space underneath the perineum and with the hollow space along the radial arc portion underneath the sacrococcygeal region. The method also includes using a supporting surface to support the seated person and positioning the seat cushion on the supporting surface such that it is underneath the seated person to support and cushion their buttocks and groin. The technical effects include reducing pressure and pain on the perineal and sacrococcygeal regions while providing comfort for the seated person.

Problems solved by technology

A common problem for those who sit for a long period of time is lower back pain that is caused by the pressure applied to the nerves around the lumbar, sacral, and coccygeal vertebrae, or even the deformation of the disk of cartilage.

However, regular donut seat cushions conventionally known in the prior art only relieve pressure from a small portion of the perineum, and they still compress tissues and structures of the buttocks surrounding the perineum like the sacrum and coccyx.

This traditional donut-style seat cushion is not an entirely satisfactory solution or way to release the pressure applied to the spine.
