IC21: The Past, Present and Future of Tilt & Recline

IC21 Handoutrs

Past, present and future design of tilt-in-space and recline will be explored with clinical relevance. TS chairs have evolved from a single pivot point to the center of mass design. TS features include: direction, degree of tilt and location of tilt axis on frame, each with clinical rationale for use. The evolution of recline design will be explored. What is shear? How has it historically been addressed? Where is design heading in the 21st century?
