Figure 9 is a line drawing perspective illustrating the effects of compound slope on pedestrians
who use wheelchairs. When travelling over a non-planar surface, such as the edge of a driveway
apron where a flared side changes slope in both directions changes over a distance of only a few
inches, a front caster or a rear drive wheel can lose contact with the rolling surface, which can
lead to a loss of balance and control or even tipping over, if extreme. |
