Abstract
A patient transport apparatus with a throttle arranged for rotation by a user between a maximum forward position and a maximum backward position to modulate propulsion via a wheel drive system. A biasing element urges the throttle toward a neutral position defined between the maximum forward and backward positions. A limiter restricts rotation of the throttle and includes a first surface. a second surface. and a guide arranged to abut the first surface to inhibit rotation beyond the maximum forward position and to abut the second surface to inhibit rotation beyond the maximum backward position. The guide is closer to the second surface than to the first surface in the neutral position such that rotation from the neutral position to the maximum forward position occurs along a first arc and rotation from the neutral position to the maximum backward position occurs along a second arc smaller than the first arc.
