Augmentation of the 100 kg ISO wheelchair test dummy to accommodate highermass: A technical note

Most of the 22 approved or developing ISO standards rely on a wheelchair te st dummy, a specialized device described in ISO 7176-11. The purpose of thi s study was to develop a means for modifying the design of the ISO 7176-11 test dummy to be suitable for testing with higher masses. The changes are b ased upon published data for obese individuals. With these data, we derived equations for determining the distribution of the additional mass among th e test dummy components, and the locations of the centers of mass. The resu lts of this study provide guidelines for adding mass to the 100 kg wheelcha ir test dummy to accommodate resting of wheelchairs designed for obese indi viduals.
