Steering Aids – Require the drivers to use minimal effort for steering or are designed specifically for quadriplegics:
- · Steering column extensions bring the steering wheel two-six inches closer to the wheelchair driver. It provides extra legroom and compensates for reduced range of movement.
- · Deep-dish steering wheels bring the steering wheel rim approximately four inches closer to the wheelchair driver and is normally used with a low-effort steering system. Lessens the range of steering motion.
- · Foot steering controls transfer hand control to foot operation. Auxiliary and secondary vehicle controls are also adapted to foot operation.
- · Horizontal steering columns are motorized, telescoping steering columns customized for those who experience limited arm strength and range of motion, and those who cannot use a conventional steering wheel.
- · Low effort steering reduces the strength needed to steer by approximately 40 percent.
- · Zero effort steering reduces the strength needed to steer by about 70 percent.
- · One-hand drive control systems are designed for people with limited or no use of lower extremities but have good strength in one arm and hand. Its main component is a knob through which the steering, brake and throttle are activated.
- · Steering spinners are designed for drivers who must steer with one hand. They are available in a variety of configurations including an amputee ring, knob, “quad-steering cuff,” palm grip, tri-pin and v-grip.
- · Steering forks support people with reduced grip function. The hand stays safely in place with support of the back of the hand and enables secure control of the vehicle.
