Tri-City inventor builds solar-powered wheelchair

A Tri-City inventor has patented the first commercially sold, solar-powered wheelchair, enabling those who use them to get around in comfort while sheltered from the sun and elements.

Aptly named The Liberator, Kurt Schneider of Kennewick, owner of Solar Mobility LLC, and his team build the cutting-edge chairs in his Richland machine shop using materials primarily made in the United States.

Those with a prescription for a group 2 mobility device may qualify for 100% coverage of The Liberator through Medicare and Medicaid or their private insurance. This also goes for veterans receiving benefits from Veterans Affairs.

The chair retails for $10,500 without insurance.

There are four categories of motorized wheelchairs based on weight capacity, speed, range and terrain handling, with group 1 being the most basic.

As a Navy medical corps veteran who broke his back multiple times, Schneider saw a need for a device to better serve those who use motorized wheelchairs.

Problem sparks invention

Schneider said the idea for the chair struck him one day in 2009 while running a food truck he owned in Richland that served up fish and chips. A customer using an electric wheelchair made the trek to get a meal, and, upon seeing him, Schneider immediately became concerned.

The wheelchair’s batteries were nearly drained, and its operator “looked like a lobster,” bright red with a sunburn from the journey. Not long after, “a friend of mine at the time was an electrician and he had conduit, so we made the first primitive one,” Schneider recalled.

They first developed what’s called the Solar Companion, a bright yellow high- visibility framework that supports a 65watt, 24-volt solar panel and doubles as a shelter from the elements.

The Solar Companion can be purchased independently and retrofitted to most group 2 chairs and scooters. It collapses by pulling two pins and continues to charge while collapsed and in ambient, indirect lighting conditions.

Schneider said he has provided solar panels to the U.S. military and the public sector for the past 24 years to meet a variety of charging needs from golf carts to handheld device charging banks.

He said the panels on The Liberator are nickel-thin, American made and high powered. They have been tested and proven to be resilient in the face of shotgun fire, hail and other impacts. They’ve even been tested underwater in the Pacific Ocean. In a word, they’re ruggedized.

This goes for the rest of the chair, too. Seating matters

After his time in the Navy, Schneider worked as a heavy equipment operator. As he dove into engineering The Liberator, he said he realized there were some other common issues with electric wheelchairs that he could improve on. One of those was the seat.

Many people who use wheelchairs de- velop ulcers and a cascade of other medical issues from sitting in an unventilated, nonergonomic chair all day. Schneider sources The Liberator’s seat from Sears Seating, which also produces seats for long-haul trucks such as Freightliner, as well as heavy equipment manufacturers such as John Deere and Caterpillar.

But even to this he made some key improvements: the Liberator’s seat reclines, lifts and adjusts from front to back and the headrest is adjustable. It’s also air conditioned, and the fabric allows for enhanced ventilation.

The Liberator features a 300-pound weight capacity while offering a low center of gravity and zero-degree turn radius with its Shark joystick, all atop a smooth air-ride suspension. There’s even a 12volt USB port. Rearview mirrors, flashing LED lights on all four sides of the solar canopy and a footplate one can stand on without tipping the chair lend additional safety.

Two 55-watt-hour NF22 gel cell batteries power The Liberator, which the Federal Aviation Administration approved for travel on airlines. The chair also can be wall charged. It’s pacemaker-safe and comes with a limited lifetime warranty.

Schneider said he went through multiple iterations and four years of development, consulting those who use motorized wheelchairs, before finally landing on this design, which he patented and received
