An adjustment apparatus for a wheelchair back that can be used with various backs, that can be adjusted in a plurality of ways using a single adjustment point, and that can be adjusted without the use of tools. In another aspect, includes a support mechanism for mounting an adjustment apparatus for a wheelchair back that can be engaged using gravity, that provides at least one support point, and that can be utilized without the use of tools. Still another aspect of the wheelchair back assembly includes a mounting clamp that is simple in construction, that provides at least one support point, and that can be easily disassembled and adjusted to accommodate upright frame members of various diameters without the use of a tool.

Wheelchair back mounting assembly

Implementations described and claimed herein include a cellular cushioning system comprising a first matrix of void cells, and a second matrix of void cells opposing the first matrix of void cells, wherein one or more peaks of each void cell in the second matrix is attached to one or more peaks of each void cell in the first matrix, and wherein the void cells of the first matrix have a higher cell resolution than the void cells of the second matrix. In another implementation, a method of manufacturing a cushioning system includes molding a first matrix of void cells, molding a second matrix of void cells, the void cells of the first matrix having a higher cell resolution than the void cells in the second matrix, and attaching peak surfaces of the void cells of the first matrix and peak surfaces of the void cells of the second matrix together.

Pressure distributing aligned arrays of cushioning void cells

A mounting clamp assembly that provides at least one support point for a wheelchair back mounting assembly, the mounting clamp assembly includes a clamp block and threaded clamp fastener extending through the clamp block and engaging a support by which the mounting clamp can be secured to a wheelchair cane; the mounting clamp assembly can be easily disassembled and adjusted to accommodate upright frame members of various diameters without the use of a tool.
