摘要： The present invention provides an assembly having a wheelchair and a lift assembly to urge the seat surface upward with respect to the frame from a lowered position when supporting the seated individual during use to an elevated position with respect to the frame assisting the individual during ingress or egress to or from the wheelchair. The lift assembly may include a mechanical linkage and an actuator. The assembly also provides at least one brake configured to block rotation of the wheelchair wheel with respect to the wheelchair frame in a locked state and disengaging with the wheels to allow rotation of the wheel with respect to the frame in an unlocked state. The assembly also provides a brake linkage communicating between the lift assembly and the brake to move the brake into the lock state when the seat surface moved to the elevated position.
