摘要： A brake actuation mechanism for a human powered mobility device, such as a lever drive wheelchair, is described. The brake actuation mechanism may include an actuator member positioned at or near an end of a lever drive such that the actuator member may be actuated or engaged by a user's thumb when grasping a lever of the human mobility device. Since the lever may drive motion of human mobility device, the user may maintain a firm grip on the lever while also manipulating or engaging the actuator member.

摘要： A drive assembly can comprise a plurality of drive arms that are configured to receive a tangential drive force and convert the tangential drive force to a torque about a first axis. A driven rotatable element can be rotatable about a second axis that is parallel to the first axis. A coupling subassembly can couple the plurality of drive arms to the driven rotatable element so that the first axis is movable with respect to the second axis in first and second dimensions that are perpendicular to each other and the first and second axes. The coupling subassembly can be configured to bias the driven rotatable element toward a position in which the first axis is collinear with the second axis.

摘要： A system and method for improving stability of a wheelchair user includes a wheelchair having sensors measuring motion parameters to sense collisions and sharp turns which may unseat the user. Neuromuscular stimulating electrodes attached to extensor and flexor muscles of the user's trunk and under the command of a controller in communication with the sensors activate the muscles during turns and collisions to counteract the forces induced. A system and method for increasing manual propulsion efficiency includes sensors for sensing motion parameters indicating completion of a manual push of the wheelchair wheels and recovery from the push. Neuromuscular stimulating electrodes attached to extensor and flexor muscles of the user's trunk and under the command of a controller in communication with the sensors activate the muscles at the appropriate time in the cycle of push and recovery.

摘要： Personal transportation aid that can be converted easily between a wheelchair and a walker. The device has handles that can be pushed forward to switch from wheelchair mode to walker mode. Pushing the handles forward causes the seat bottom of the wheelchair to flip up, opening a space where the user can stand to use the walker; the front wheels of the wheelchair are also pushed forward. Pulling the handles backwards returns the device to its wheelchair configuration, with the seat bottom flipped down and the front wheels moved backwards. Simple mechanical linkages may be used to flip the seat bottom up and down, and to push the front wheels forward and backwards; therefore the device does not require a power source or actuators.

摘要： The present invention relates to an electrical assistance device (1) for a wheelchair (100) having a seat (103) and at least one rear wheel (104, 105) having a tyre (110), the electrical assistance device (1) comprising: at least one motor (2) having a rotor (22) connected to a pinion (4) designed to mesh with a complementary toothset of the tyre (110), and a mobile arm (6) connecting said motor (2) to the wheelchair (100). The mobile arm (6) allows said motor (2) to be manoeuvred between an engaged position in which the pinion (4) is in contact with the complementary toothset of said tyre (110), a disengaged position in which the pinion (4) is not in contact with the complementary toothset of said tyre (110) and a transport position in which the pinion (4) is distanced from the tyre (110) and retracted beneath the seat (103).

摘要： This invention is a rotational manual propulsion wheel chair hand pedal to be fitted to the axles of both wheels of a wheel chair. The rotational wheel chair hand pedal is attached to the two large wheels of a wheel chair by means of being directly attached to the axles and or hubs securely of the wheel chair's wheels, or surrounding the hubs of the wheel chair's wheels. The rotational wheel chair hand pedal has an arm, which fits from the wheel chair's axle and or hub to the wheel chairs wheel's rim. The position of the handles is fixed by retractable and is adjustable by pressing a button at the end of the handle to retract the pins.

摘要： A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.
