3.5

anthropomorphic test device

ATD

articulated physical analogue of the human body used to represent a wheelchair occupant in a test

3.6

belt

3.8

clamp-type tiedown

method of wheelchair tiedown or securement that uses only mechanical linkages and/or grips requiring manual positioning and tensioning of the end fittings to the wheelchair

3.9

docking-type tiedown

docking-type securement

method of wheelchair tiedown by which portions of the wheelchair structure, or add-on components fastened to the wheelchair, align, mate and engage with a docking tiedown device fastened to the vehicle, upon manoeuvring the wheelchair into position in the vehicle

Note 1 to entry: Securement of the wheelchair may occur automatically during wheelchair engagement, or could require manual intervention through operation of a mechanical lever or electrical switch. Release of the wheelchair will usually require operation of a mechanical lever or electrical switch.

3.10

docking tiedown device

docking securement device

3.11

excursion

horizontal movement of an ATD or wheelchair during a test relative to its initial position on an impact sled

3.12

forward-facing

orientation in which the wheelchair-seated occupant faces the front of the vehicle with the wheelchair reference plane within 10° of the longitudinal axis of the vehicle

3.13

four-point tiedown

wheelchair tiedown that attaches to the wheelchair frame at four separate securement points and also attaches to the vehicle at four separate anchor points

3.14

four-point strap-type tiedown

four-point tiedown that uses four strap assemblies to secure the wheelchair in the vehicle

3.15

H-point

one of a pair of points located on the left and right sides of the pelvic region of an anthropomorphic test device (ATD) that represent the approximate locations of the human hip joint centre in the side views, as specified by the ATD manufacturer

3.16

head restraint

device intended to limit rearward excursion of the wheelchair occupant’s head in a vehicle impact

3.17

impact simulator

device for accelerating, decelerating, or a combination of decelerating and accelerating, a section of a vehicle or simulated vehicle structures, including instrumentation for measuring data required by this standard

3.18

impact sled

part of an impact simulator on which components can be mounted for impact testing

3.19
