Abstract: Angle adjustable backrest made of a lightweight, durable, adjustable, backrest for ultralight manual wheelchairs. Light-weight material can include composites for a rigid backrest for promotion of healthier and functional interface. Angle adjustment can be any desired range such as a range from ?5 degree to 55 degrees (i.e. 85 degrees to 145 degree with respect to horizontal with the seat). No tools are necessary for any of the angle adjustments. The backrest has a horizontal adjustment (fore-aft) that can be any desired range such as 1 inch. The height selection depends on the length of the wheelchair frame tubes. The present invention improves the ease and simplicity of adjusting the backrest by or for the user, as well as enhances the aesthetic appearance and adds features necessary for achieving commercial readiness. The present invention can be retro fit onto a wide range for ultralight wheelchairs.
