ABSTRACT:
A wheelchair brake system is provided that allows an operator of the brake system to retard and/or stop the motion of the wheelchair. The brake system provides for independent and variable application of a braking force to wheels of the wheelchair. The brake system includes first and second brake force application assemblies, first and second braking assemblies, and actuation lines coupling the respective brake force application assembly to the braking assembly. The brake force application assemblies may be associated with handles of the wheelchair that allow a secondary or ancillary operator to apply a braking force, but may be associated with armrests of the wheelchair for use by an occupant. The brake force application assemblies are rotationally positionable and/or pivotally positionable to achieve various orientations thereof. This provides ergonomic placement of the handles for comfort and ease of brake force application.
