An external structural brace apparatus for supporting a user in a semi standing position on a surface includes first and second support extension beams that to attach to the surface, also included is a channel having a base with first and second legs, wherein the first and second legs extend in the same direction from opposing sides of the base, the first leg is affixed to the first support structure and the second leg is affixed to the second support structure, the channel can be lockably positioned along the first and second beams. In addition, a saddle seat with a midpoint extension portion, the saddle is attached between the first and second legs and positioned such that the midpoint extension extends opposite of the base, wherein operationally the user partially rests their buttocks on the saddle and leans their back against the base to assume a semi supported standing posture.

A mobility device, including a base, a first omnidirectional wheel mounted at a first side of a forward portion of the base to rotate about a first axis, a second omnidirectional wheel mounted at a second side of the forward portion of the base to rotate about the first axis, a third wheel mounted at a rearward portion of the base to rotate about a second axis, a drive system to move the first omnidirectional wheel, the second omnidirectional wheel, and the third wheel according to input received indicating a desired motion of the mobility device, a seat for a user of the mobility device, and a linear actuator coupling the seat to the base to drive the adjustable seat in a vertical direction according to the input received indicating the desired motion of the mobility device.

A motorized wheelchair for disabled or elderly users has a frame, a seat for the disabled driver, a handlebar, a motor provided with an acceleration apparatus, a wheel assembly and a braking apparatus of the wheels. The wheelchair has a bivalent control device that is capable of being interfaced with the acceleration apparatus of the motor and with the braking apparatus of the wheels.

The portable therapy chair is a wheelchair. The portable therapy chair is an exercise device used by a patient. The patient sits in the portable therapy chair to exercise. The portable therapy chair provides a counterforce for use by the patient during leg exercises. The portable therapy chair comprises a seat, a plurality of resistance pedals, and an assistance circuit. The plurality of resistance pedals and the assistance circuit attaches to the seat. The seat is a collapsible structure such that the volume of the portable therapy chair reduces for transport. The patient moves the plurality of resistance pedals. The plurality of resistance pedals provides a counterforce against the movement by the patient. The assistance circuit is an electric circuit. The assistance circuit generates the counterforce provided to the patient.

This relates to a propulsion attachment for a manual wheelchair and methods of operation. The propulsion attachment can include three wheels, a motor, a gearbox, and a handlebar. The propulsion attachment can attach to the footrest of the wheelchair using a pin. The motor can be located in the rear side of the propulsion attachment and can push the user in a forward direction. Alternatively, the user can manipulate a switch located on the handlebar to allow the propulsion attachment to pull the user in a reverse direction. The propulsion attachment can include a plurality of brakes, where each brake can control one of the wheels. Additionally, the propulsion attachment can operate at variable speeds using the motor and the power from one or both batteries.

A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The user is able to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.
