Full Sized Accessible Wheelchair Vans

Leave a reply

Ask people with disAbilities—when purchasing a handicap or accessible van—size matters. The full-sized van is a good option for those with a large family, those who travel often, those with additional equipment and accessories, those who need to tow large loads, or big or tall passengers or drivers.

Most minivans do not have roof modifications so you don’t have as much interior space.  Roomy full-size vans gain space by raising the roof, lowering the floor or both, and also have the advantage of more power and load carrying capacity.

Full-sized van:

  • Its weight-carrying capacity is significantly more than a minivan’s. It can hold the weight of a power wheelchair and even accommodate two individuals in wheelchairs.
  • It offers a lowered floor for the center, passenger or driver position; raised roof, raised doors; lifts and adaptive driving aids.
  • A raised roof makes it easy for someone to enter the van seated in a wheelchair or for a caretaker to tend to them or walk in and out of the entrance.
  • Doors are raised in conjunction with a roof to enable a person in a wheelchair to enter without having to bend over or have a caretaker tilt the wheelchair back.
  • Larger wheelchairs or motorized wheelchairs require floor-lowering or roof-raising modifications that a full-size van allows.

Adaptive Driving for Persons with Physical Limitations: Adaptive Driving Aids/Modifications

Leave a reply

With the use of appropriate adaptive aids an individual with most types of physical disability can continue to drive safely. A variety of devices are available to meet the individual driver’s needs and preferences. The following is a list of the more common modifications available. They should be tried in an actual driving situation before making a final decision. (For liability issues work with a certified adaptive driving specialist).

Automatic transmission: replaces clutch and manual shift

Power Steering: permits one-hand steering wheel operation

Power Brakes: needed for hand controls and other adaptive aids

Steering Devices: spinner knob, amputee ring, quad fork, tri pin, or custom device

Floor Mounted Steering: floor steering wheel for foot control

Modified Effort Steering: reduces strength needed to operate power steering or brake to accommodate low strength and/or endurance.

Left Foot Accelerator: eliminates left leg cross-over

Foot Pedal Extensions: raises height of brake and accelerator

Hand Controls: control operates brake/accelerator with single lever and activates secondary controls (horn, wipers, turn signals, etc.) *temporary or mounted hand controls are not recommended by Veterans Administration
Electric Gear Selector: permits left hand operation
Right Hand Turn Signal: permits right hand operation without cross-over
Remote Switches: reposition or build up secondary controls (horn, wipers, turn signals, etc.) to accommodate driver’s specific disability
Seat Belts: shoulder and lap belt adjustments may be needed
Power Seats: eases access for transferring to a regular captain’s seat
Custom Seats: creates balance, positioning, and stability
Lifts and Ramps: permits access into and out of vehicle
Wheelchair/Scooter Lifts: assists in lifting wheelchairs and scooters in and out of vehicle
Wheelchair Carriers: permits carrying of wheelchair outside of vehicle

Adaptive Driving Aids: Reduced Effort Modifications

Leave a reply

Experienced users of adaptive driving aids, as well as those who have just been introduced to them, will appreciate the depth of experience and the number of options available to them here at VMi New England Mobility Center and Automotive Innovations, Inc.

Adaptive driving aids are as diverse as the people who use them, but they do fall into several distinct categories; basic driving aids, reduced effort modifications and advanced driving controls.

Reduced Effort Modifications

Reduced Effort Steering
Reduced effort modifications are used in conjunction with hand controls and other adaptations to reduce the physical strength required to perform the operations of braking and steering. Reduced effort braking and reduced effort steering are modification packages that make the steering wheel or brake pedal easier to turn or push. The level of assistance or “reduced-effort” is adjusted to the level prescribed by the driving rehabilitation specialist, based on the strength of the driver.

  • Drive-Master’s low effort and no effort braking modifications significantly reduces the required pressure needed to press down on a pedal to brake.
  • Drive-Master’s reduced effort steering modification reduces the amount of effort it takes to move a steering wheel. There is low effort to no effort available depending on the model of car and tire size.

Advanced Driving Controls

Advanced driving controls, or “high-tech driving systems” have advanced tremendously over the years, thus creating options for drivers with higher levels of disability. Advanced driving controls are truly a custom solution. As a result, the key components of these systems are combined, fitted and installed based on an extremely thorough process of evaluation, prescription and fine-tuning.

Hand Controls
Hand Controls in the advanced driving aid category are of course more advanced and are typically for individuals with very limited mobility and strength for operating a vehicle. A slight touch of various adaptive devices allow the car to accelerate and brake with ease.

  • Electric Gas and Brakes are operated from an electric servo in the form of a joystick or lever input device. Individuals can then use their hands to control their speed and to brake.
  • Pneumatic Gas and Brakes are operated from an air pressure system and controlled by an easy joystick, foot pedal or other device.

Steering Controls

  • Horizontal Steering accommodates a limited range of motion when the driver cannot use a conventional steering wheel.
  • Reduced and Zero Effort steering is for users who do not have adequate strength to operate the vehicle with factory resistance levels.
  • Electric steering allows the steering control to be located almost anywhere to assist the operator. They can be operated in the forms of miniature steering wheels or joysticks.

Electronic Gear Selection
Electronic Gear Selection allows the operator to push a button for a gear selection.

Remote Accessory Controls

  • Voice Scan uses one to two targets or buttons to operate a multitude of functions within the vehicle while utilizing a verbal audible menu.
  • Single Touch allows vehicle functions to be moved to a different location in order to fit the needs of the disabled driver.
