Custom Solid Back
Our backs are fabricated out of 1/2” plywood and laminated on both the front and back faces with 1/8” black ABS plastic. The backs are permanently attached to the wheelchair backposts making them non-removable and the wheelchairs to be non-folding. Our bracket system can clamp to 3/4”, 7/8 or 1” diameter backpost tubing. The hardware system we use is extremely strong. All attaching bolts are grade five or above and are fastened with nylock nuts that will not loosen and will not fall off. There are no tee nuts or slide nuts to allow the bolts to loosen for structural back attachments. The extruded structural 90 degree angles we use will not bend. The structures are cut from a 25' bar that was fabricated from the mill at 90 degrees. The angles we use have never broken or bent out of position. The angles attach to the solid back with 2 bolts and nylock nuts per angle. The angles are slotted to allow for excessive width tolerances from the wheelchair manufacturers. The angles are attached to the wheelchair backposts with heavy duty steel clips that are vinyl coated to prevent backpost damage. The clips completely encircle the backposts and lock to the 90 degree structural angles behind the posts with bolts and nylock nuts. There is no depth adjustment.
For tilt in space wheelchairs and wheelchairs with 1” OD stroller handle backposts, the solid backs are mounted in front of the posts. The backs are the same width as the wheelchairs. For all other wheelchairs, the solid backs are mounted between the backposts. For backs between the posts, the back width is the wheelchair width less the diameter of the left & right back posts minus 7/8”. All backs have 1” foam and are covered in black vinyl that is anti-microbial, anti-bacterial and anti-fungal. The covering is attached with (4) bolts and easy to remove or replace, making cleaning simple. This is the most hygienic system you can purchase.
Lateral supports can be added to any back. The supports mount in front of the solid back and are fastened with accessible bolts and lock nuts. The back has a vertical line of holes spaced one inch apart.
When you give us the chest width and axilla height, we will set the width spacing of the vertical line of holes for the lateral trunk supports.
In our systems, the lateral trunk supports mount in front of our solid backs behind the back foam. This makes all adjustments for width and height of the lateral supports easy.
All backs have a back pad that is rectangular in shape. 1) for backs with lateral trunk supports the back pad is 2” wider than the users chest width and the height is what you specify. 2) for backs without lateral trunk supports the back pad is 2” less than the width of the solid back and the height is what you specify. All backs are designed to sit on top of a seat cushion.
Solid back larger then 20 wide x 24 high need to call for quote.
