A modulable sports wheelchair includes a supporting frame, a front wheel, a pair of rear wheels and a sitting cage. The supporting frame is divided into a front half-frame connecting a support for the front wheel with a frame structure carrying the rear wheels. The frame structure has at least two longitudinal sides oriented in the movement direction of the wheelchair and two transverse sides spaced and oriented in the other direction so as to form the cage, which takes the shape of a compartment free from internal structural elements and is adapted to receive an athlete with an optimal position for propelling the wheelchair depending on the level and type of disability of the athlete.

Apparatus and method using two couplings connecting a wheelchair to a walker for safely assisting a patient regaining their ability to walk. Physical therapists use the walker to train patients on walking to build strength, endurance, and balance. The couplings provide a fixed gap between the wheelchair and walker and keeps the wheelchair close to the patient. The patient can easily sit in the wheelchair, and the presence of the wheelchair minimizes the risk of falling, allows the patient to rest when fatigued, provides a sense of security, and eliminates a need for an assistance to push the wheelchair behind the patient.

An embodiment seating device includes a frame unit including a chair region capable of supporting a user and a leg region extending downward from the chair region, a backrest unit disposed at a rear side of the frame unit, and a handle unit coupled to a first side of the frame unit, the handle unit including a fixing handle body region having a first side coupled to the frame unit and rotatable relative to the frame unit and a lifting handle body region having a first side coupled to the fixing handle body region and rectilinearly movable relative to the fixing handle body region.

The presently disclosure describes a motion assistance system for a wheelchair, for example, a powered drive wheel system that can continually drive a wheelchair in a circular or elliptical path. The motion assistance system comprises a mounting mechanism attachable to one or more structural elements of the wheelchair, and a drive linkage pivotable with respect to the mounting mechanism. A drive wheel can be mounted to an end of the drive linkage such that the drive wheel contacts the ground when installed on the wheelchair. The drive wheel comprises a plurality of lateral rollers positioned radially about the circumference of the power drive wheel. The lateral rollers can rotate about an axis tangential to the circumference of the drive wheel in order to facilitate driving the wheelchair in a radial direction.

A medical chair includes a base, a seat, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a first actuator for tilting the seat with respect to the base, a second actuator for lifting the seat with respect to the base, and a leg rest actuator adapted to move the leg rest. The chair also includes a controller adapted to control the first and second actuators to move the seat between a first position and a second position such that the seat is both lifted and tilted at the same time as the seat moves from the first position to the second position, and wherein the controller is adapted to control the leg rest actuator such that the leg rest maintains a substantially constant orientation with respect to the floor.

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.

The invention relates to an auxiliary mobility system for a wheelchair, comprising a frame, at least one wheel-bearing part and at least one steering element or handlebar, said bearing part being connected to the frame such that it can rotate concentrically about its axial axis under the action of the steering element. The system also comprises means for rotating the bearing part concentrically in relation to an axis substantially parallel to the rotation axis of the wheel.

A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and at least one tiller, configured such that forward and backward movement of said tiller will translate into movement of both steering wheels, wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.

A dynamic seating and walking wheelchair includes an active seat and a frame. The active seat is configured to move from a seated position to a standing position. The active seat includes a seat back with an upper end and a lower end, and a seat bottom with a front end and a rear end. The rear end of the seat bottom is rotatable about a movable pivot axis approximate to the lower end of the seat back from the seated position of approximately horizontal to the standing position of approximately vertical. The frame is configured to support the active seat. Wherein, when the active seat moves from a seated position to a standing position, the movable pivot axis moves both up and backwards.
