Range of Reach
A wheelchair user's movement
pivots around his or her shoulders. Therefore, the range of reach
is limited, approximately 630 mm for an adult male.
While sitting in a wheel chair,
the height of the eyes from the floor is about 1190 mm for an adult
male. (as shown in Figure-3)
Fig-3. Range of Reach
A wheelchair has a footplate
and leg rest attached in front of the seat. (The footplate extends
about 350 mm in the front of the knee). The footplate may prevent
a wheelchair from getting close enough to an object.
Manually operated equipment must be designed to be easily accessible
from a wheelchair.
Make sure that the coin slots of vending machines etc. are located
no higher than 1200 mm.
Allow a space at least 350 mm deep and 700 mm high under a counter,
stand, etc (as shown in Figure-4).
