Abstract
Wheelchair headrests generally provide support with a fixed position or a single lateral rotation with manually adjustable paddings and forehead straps. The lack of functionality in headrests limits the user from performing daily activities and causes discomfort and fatigue. This paper presents the design of a tendon constrained inflatable for wheelchair headrest interface that demonstrates tailorable rigid load-bearing thresholds for accommodating different users, compact stow for easy transfer from a wheelchair and for daily activities, and scalable thresholds with respect to pressure for temporary high stabilization of the user’s head when fatigued or against vibrations/motions of a vehicle.
