Lumbar Cushion Support Attachment for Backpacks

Abstract

A portable lumbar cushion support attachment for backpacks for providing support to the lower spine and surrounding para-lumbar musculature of the wearer. The present invention is for a memory foam cushion which adjustably supports the lower spine in a proper position, alleviating lower back pain caused by improper posture and fatigue and also preventing further instances of lower back pain. In one embodiment, side straps are attached onto the bottom triangular strap regions of the backpack. The cushion is hemi-elliptical design which is positioned horizontally in the lower back region such that the cushion supports the spine and the surrounding musculature and the L1-L5 vertebrae. The cushion extends outwards, pushing against the lumbar spine, causing pressure to be created against the backpack and into the lower back, thus alleviating back pain and maintaining the lower back in its natural straight position.

What is claimed is: 
     
         1 . A lumbar cushion support device configured for attachment to backpacks, said device comprising:
 a block of memory foam,   a layer of rigid foam or other rigid material,   a backpack attachment mechanism, and   a cover,   
       wherein
 the block of memory foam comprises a curved side configured for positioning against a wearer's lower back; 
 said layer of rigid foam is provided on a side of the block of memory foam opposite the curved side, acting as a base of the device configured for touching the backpack, 
 said cover covering the memory foam and rigid foam or other rigid material, and 
 said attachment mechanism optionally comprises straps extending from two locations on the device and each attached to a connector. 
 
     
     
         2 . The device according to  claim 1 , wherein the width of the device is greater than the thickness of the device. 
     
     
         3 . The device according to  claim 1 , wherein the width of the device is between 10 inches and 14 inches and the height dimension is between 3 inches and 7 inches and the thickness dimension is between 2 to 4 inches. 
     
     
         4 . The device according to  claim 1 , wherein the width is 12 inches and the height is 6 inches and the thickness is 3 inches. 
     
     
         5 . The device according to  claim 1 , wherein the memory foam comprises open cell high density polyurethane foam. 
     
     
         6 . The device according to  claim 1 , wherein the cover comprises gel fabric, microfiber, microsuede, silk, cotton, nylon, satin, sateen, or a natural fabric, or a synthetic fabric. 
     
     
         7 . The device according to  claim 1 , wherein the side of the memory foam opposite the curved side comprises a rectangular shape. 
     
     
         8 . A method of achieving a proper posture of the spine while wearing the backpack, comprising the steps of; providing the device of  claim 1 , clipping said side straps with said mitten clips onto the bottom triangular portion of the straps of the backpack, adjusting said mitten clips based on the wearer's height, size, and location of lumbar curve, said device centrally and horizontally located in the middle of the backpack, wherein the hemi-elliptical shape of the device will cause more pressure on the spine and back of the wearer, and wherein said device will provide support for the surrounding musculature and thus causing a proper position of the back and body to be achieved.
