However, we do know about the first self-propelled wheelchair that was invented in 1655 by Stephan Farfler in Nuremberg, a 22 year old paraplegic clock-maker who built it to aid his own mobility.

Since then, there have been various technological and design advancements to improve the wheelchair. We share some of the patents that protect this inventions:

This convertible wheelchair has a detachable lift module that elevates the chair at three secure points. This system allows easy lifting of the wheelchair, accommodating a patient at a preferred height. Not only does it provide seamless elevation, but the wheelchair can also transform into multiple examination configurations, revolutionizing patient care with unparalleled versatility.

Introducing a dynamic seating and walking wheelchair with an active seat that smoothly shifts from sitting to standing. The innovative design includes a movable pivot axis, enabling the seat back to rotate from a horizontal to a vertical position. Supported by a specialized frame, this wheelchair redefines mobility, moving both upwards and backwards during the transition.

This innovative wheelchair allows for easy transfer from the back of the chair, eliminating the need to maneuver over the armrest. By unlocking the back strap, the process becomes smoother, enhancing the quality of life and preserving personal dignity. This not only reduces the need for additional assistance but also promotes independence, drawing less attention to the disability and subsequently boosting self-esteem and mental well-being.

This method involves seamlessly repositioning occupants between lowered and raised positions. The wheelchair is equipped with a frame, a movable seat, drive wheel, arm assemblies, and sensors. These arm assemblies dynamically adapt to ground conditions, with arm limiters ensuring safe operation based on seat position and surface conditions. This method intelligently adjusts the wheelchair’s maximum speed when the seat is elevated, utilizing sensor data for optimal performance.

This wheelchair features a frame, a seat, and a set of wheels strategically positioned for optimal stability. What sets it apart is the independent control system for each wheel, including forward and rearward wheels, and drive wheels. This innovative design allows for precise adjustment of the vertical position of each wheel relative to the frame.
