| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 17 |
This document specifies apparatus, test methods, and disclosure requirements for determination of lateral stability properties of wheelchair seat cushions by measuring the response from the cushion to a shift in the centre of mass. It provides a method of determining changes in a particular physical and mechanical property of the cushion. It does not provide information specific to cushion performance for a particular individual user. It does not provide information related to anterior-posterior stability, nor to stability contributions from cushion edges.
Test conditions simulate a symmetric anatomy.
Loads are intended to represent those seen under the pelvis of a 40-60th percentile wheelchair user.
This document may be applicable to seat cushions in other applications.
