The present disclosure describes a system and method for a providing an assistive driving force to a wheelchair.

Assistive driving system for a wheelchair and method for controlling assistive driving system

The presently disclosure describes a system for stabilizing a wheelchair. The system includes at least one caster arm configured to maintain contact with a surface underlying the wheelchair. The at least one caster arm includes a force sensing system configured to measure a force exerted on the underlying surface by the at least one caster arm; and an actuator to configured adjust a position of the at least one caster arm based at least in part on the measured force.

Self-balancing wheelchair

The presently disclosure describes a system for a 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 user's 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.

Assistive driving system for a wheelchair

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.

Motion assistance system for wheelchairs

The present 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 user's 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.

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.

System and method for adjusting a wheelchair seat

A wheelchair-accessible treadmill with a safety system allowing wheelchair users to exercise without the risk off steering off-course, tipping over, or rolling backwards off the treadmill. The wheelchair is secured by straps or similar means to two or more linear bearings that move along the side of the treadmill on rods or in tracks. When securely fastened, these allow the wheelchair to move forward and backward on the treadmill belt. The treadmill belt may be wider than standard, the height may be lower than standard, and a ramp may be used for access. An optical sensor may be used to determine the forward and backward movement of the wheelchair user. Wheelchair specific programs may be available through the control panel.
