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.

DESCRIPTION (provided by applicant): Wheelchair Drive System Over half of the wheelchair user population has developed upper extremity (UE) pain and injury. One of the activities that likely contribute to the development of injury is wheelchair propulsion. A number of technologies have been developed to address this issue including ergonomic pushrims, geared hub wheels, lever drives and pushrim-activated power assist wheels. While the non-powered technologies have been shown to incrementally reduce demandon the UE, power assist wheels can practically eliminate the demand. However, it is not reasonable to use power assist wheels when powered off due to their considerable weight. In essence, they are powered wheelchairs with pushrim-mounted joysticks. Thereis a need to develop a light-weight removable power drive system for a manual wheelchair that can be used selectively by the individual to reduce UE demand during the course of everyday propulsion activities. This project will develop a wheelchair drive system to meet this need and evaluate its efficacy through a series of focus group assessments and a long-term use study. As a result of this project, wheelchair users will gain access to technology that will reduce UE demand and hopefully reduce their riskof developing overuse injuries. PUBLIC HEALTH RELEVANCE: Wheelchair Drive System Relevance to Public Health Manual wheelchair users are at considerable risk of developing upper limb overuse injuries. One preventative measure is to reduce demand on theupper extremities during propulsion. This project will develop a lightweight removable drive system that can be used to provide propulsion assistance, thereby reducing physical demand and the likelihood of developing overuse injuries.

A wheelchair including a base assembly that has a first side and a second side. At least one caster and a drive wheel are mounted to each of the first and second sides. The wheelchair includes a seat assembly having a seat and a backrest and an actuator assembly having a plurality of actuators. Each actuator can expand and retract and includes a first end pivotably connected to the base assembly and a second end pivotably connected to the seat assembly. The actuator assembly allows for at least four degrees of movement of the seat assembly with respect to the base assembly. The wheelchair includes a computer that is connected to the actuators and that controls the movement of the actuators. The computer moves the actuators to vary the position of the seat assembly with respect to the base assembly.

The presently disclosure describes a system for providing an assistive driving force to a wheelchair. The system comprises a power assist system which includes a motion sensing system that is configured to detect the motion of the power assist system, and hence of the wheelchair, and a power assist drive system that is configured to provide an assistive drive force. The system also comprises a sensor, such as may be embedded in a wearable wristband, that is configured to detect the motion of a users hand and that is in communication with the power assist system. The system may be configured to determine whether the wheelchair is being manually pushed based at least in part on the user motion, and to activate an assistive drive force in response to a manual push. The system may also be configured to determine whether the wheelchair is being manually braked based at least in part on the user motion, and to deactivate an assistive drive force in response to a manual brake.
