20090051138 | Hand grip motion control capabilities for a lever propulsion wheelchair - A motion control system for lever propulsion of a wheelchair enables a number of different manipulations at the hand grip of the lever. In some embodiments, as many as five user-controlled operations may be performed without need to remove a hand from the hand grip. A user applies force to the hand grip to initiate the motion lever in its forward and rearward strokes. In addition, the hand grip may be pivoted relative to the lever in order to control a brake. A parking brake mechanism may be provided at the hand grip to apply constant brake force. The direction shifter at the top of the hand grip may be used to shift between forward, neutral and rearward modes of operation. In some embodiments, steering of a front caster wheel is possible by rotating the hand grip. Further along the lever, the power applied per lever stroke is adjustable. | 02-26-2009 |
20090051139 | Wheelchair retrofit assembly with multiple dimensions of adjustment - An assembly for attachment of a propulsion system to a wheelchair frame includes a clamp which remains fixed to the frame, while an attachment device that enables three dimensions of adjustability permits quick release of a main wheel and the propulsion system (e.g., lever drive, pushrim and motor drive) that propels the main wheel. The clamp includes a first alignment feature, such as a pin. A spring-loaded latch may also be included. The attachment device includes a second alignment feature, such as a hole or slot, configured to mate with the first. To permit alignment for a number of different wheelchair frame geometries, the attachment device is rotatable to provide angular adjustability, structured to permit lengthwise adjustability, and coupled using hardware which provides offset adjustability in a direction generally parallel to the axis of the wheel. | 02-26-2009 |

The arc plate defines a first track and a second track that guide the tilting of the seat frame relative to the frame. The first track and second track may have non-constant curvatures. Further, the first track and second track may be arranged non-concentrically on the arc plate and may have different lengths. | 04-02-2009 |
20090108561 | CURB CLIMBING WHEELCHAIR ATTACHMENT - A curb climbing wheelchair system having left and right side attachments are designed to be attached to left and right side portions, respectively, of a standard wheelchair to enable a wheelchair occupant to climb a curb, bump or other obstruction without the aid of another individual. Each attachment includes a ramp extending from a telescoping arm that is designed to be attached, via a clamping system, to one side of the wheelchair. When not in use, the ramps are folded and stowed away on the sides of the wheelchair. During use, the ends of the ramps are placed on the curb to allow the wheelchair occupant to roll up the curb. To retrieve the ramps (now disposed behind the wheelchair), the wheelchair occupant moves the telescoping arms, if necessary with the aid of an attached circular handle, to lift the ramps thus allowing the wheelchair occupant to grab the ramps. The retrieved ramps then are stowed away until needed. | 04-30-2009 |
20090256331 | Vehicle - By bending and stretching a link mechanism, both left and right wheels of a vehicle can be inclined toward inside of cornering to generate a camber thrust as a lateral force, i.e. an increase in cornering force. Further, by bending and stretching the link mechanism, the passenger compartment can be inclined in accordance with inclination of a connecting link, and thus the center of gravity of the vehicle can be moved toward its inner wheel during cornering. By preventing lifting of the inner wheel during cornering, cornering performance is improved. Because the passenger compartment is inclined toward the inner wheel during cornering, centrifugal force is less likely to be felt by the occupant. | 10-15-2009 |
