The Development of a Surrogate Mobility Aid (SMA)

The most severe loading conditions to which mobility aids and mobility aid securements and occupant restraint (MASOR) systems may be subjected will occur during a vehicle crash. Two new Canadian Standards CSA/Z604 and CSA/Z605 have been written to standardise the crash performance requirements for both the mobility aids and the MASOR systems. For the MASOR system dynamic test requirement a reusable surrogate mobility aid (SMA) is used, both to reduce test costs and to ensure test consistency. The basis for the design of this device and the rationale for the test requirements are presented, along with some initial test results.
