The TiLite Twist wheelchair with the Transit Tie-Down Option was tested in accordance with ISO 7176-19
Section 5.2 using a surrogate wheelchair tie-down device that complied with Annex E of ISO 7176-19 and
a three-point, vehicle-anchored, occupant restraint system consisting of a shoulder belt and a pelvic belt.
The anthropomorphic test dummy weighed as set forth in the table above. The wheelchair that was tested
passed the frontal impact test congured as described above.
The rider of a TiLite Twist wheelchair must not weigh more than the Maximum User Weight stated above.
If there are items attached to the wheelchair, such as backpacks, seat pouches, etc., the weight of such
attached items must be counted as part of the Maximum User Weight limit for the wheelchair. In other
words, if the wheelchair rider has a 20 lb (9.1 kg) backpack attached to the wheelchair, then the wheelchair
rider must not weigh more than the Maximum User Weight in Table 15-1 less 20 lbs. The TiLite Twist
wheelchair was not tested with a wheelchair-anchored pelvic belt, and TiLite does not offer this
wheelchair with a wheelchair-anchored pelvic belt.
