Recommendations for Clear Zones
Clear zones are recommended areas in which hard or sharp installation components or objects
should not be placed. The clear zone recommendations in ISO 10542 are based on the way in
which an occupant moves during a crash/collision. To reduce the risk of injuries to the head
and chest, hard vehicle components and parts for WTORS which lie within the clear zones
should be covered with padding that meets the requirements with regard to the hardness of
materials as specified in FMVSS 201, ECE regulation no. 21 or EU directive 74/60.
The wheelchair and user must be placed facing forward in the vehicle.
FCZ = Frontal Clear Zone
650 mm. when both lap belts and diagonal belts are used.
950 mm. when only lap belts are used.
The use of both lap belts and diagonal belts is recommended to reduce the risk of head and
chest impact. The majority of countries require the use of both lap belts and diagonal belts. It
may be impossible to comply with the recommendation for FCZ if the wheelchair is used by a
person driving the vehicle themselves.
HHT= Seated head height
Approx. 1200 mm for a small adult female. Approx. 1550 mm for a tall adult male.

*= Installation height from the floor
and up to the shoulder and the
shoulder belt's top anchoring
point depends on the height of
both the user and the wheelchair.
The shoulder belt's anchoring
point must be located in such a
manner, that the belt runs over the
midpoint of the shoulder.
Safety belts must not be held
away from the body by wheelchair
components or parts such
as armrests or wheels.
