Abstract
A standard research methodology for comparing the performance of
various motorcyclist crash protection devices such as airbags and
leg protectors, has been developed under the auspices of the
International Standards Organization, ISO/TC22/SC22/WG22. This
methodology employs an Anthropometric Test Device, ATD, specially
designed to represent a motorcyclist. Based on the Hybrid III, it
incorporates several special features specific to this application.
Among these is a neck which includes several unique performance
specifications.
Foremost among these requirements is the recognition that the
initial head-neck orientation of the motorcyclists is both
different from the automobile occupant and will vary from vehicle
to vehicle. Secondly, the helmeted head of he motorcyclist ATD will
be subjected to inertial and impact loading not only in the
fore-aft direction, but also laterally. Finally, the head and neck
will be subjected to torsional loading.
Some of these requirements have been incorporated in Draft
International Standard 13232. Others need further development
particularly if the dummy is to be used for motorcycle airbag
research. This paper discusses how current biomechanical
specifications for frontal and side impact automotive ATDs are
applied to this special application. Additionally, new
specifications for neck torsional response are proposed. A set of
general criteria for these has been proposed and accepted by the
relevant technical committees and could form the basis for possible
neck development.
