This invention relates generally to the field of portable cushions and more specifically to a support adjustable lumbar support cushion.
Portable back cushions for use while seated on a chair or the seat of a vehicle are well known.
When driving long distances, or sitting in a chair for long periods of time, a person's lumbar area can benefit from extra cushioning support.
Some cushions offer the option of changing the degree of support by inflating or deflating a pillow located in the lumbar area. However, inflatable cushions do not offer the same degree of comfort as resilient foam cushions. Therefore, it would be a novel advantage to have a lumbar support cushion that is made of a resilient material, and can be quickly removed and replaced by smaller or larger lumbar support members according to the user's needs and comfort requirements.
The primary object of the invention is to provide a lumbar support cushion that allows the user to easily remove and replace the lumbar support component with larger or smaller supports.
Another object of the invention is to provide a lumbar support cushion where the lumbar support is made from closed cell polyethylene foam.
Another object of the invention is to provide a lumbar support cushion where a plurality of support members nest into one another to allow for different degrees of support.
A further object of the invention is to provide a lumbar support cushion where the support member is D shaped to provide ideal back support.
Yet another object of the invention is to provide a lumbar support cushion where the D shaped support member is hollow to provide greater resiliency.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed a lumbar support cushion comprising: a cushion cover capable of forming an L shaped cushion, a poly foam padding member, one or more polyethylene closed cell foam lumbar support members, said foam padding member and said lumbar support member enclosed within said L shaped cushion cover, said cushion cover including an integral hinged flap to allow for the insertion and removal of said lumbar support member, and said hinged flap being held closed by a hook and loop closure member.
The drawings constitute a part of this specification and include exemplary embodiments to the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
