A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure supporting a track assembly having a belt. A motor selectively generates torque to drive the belt. A user interface is arranged for engagement by the user, and has a direction input control for selecting a drive direction of the motor, and an activation input control for operating the motor to drive the belt. A controller in communication with the motor and the user interface is configured to limit operation of the motor in response to user engagement of the activation input control preceding engagement of the direction input control to prevent driving the belt, and to permit operation of the motor in response to user engagement of the activation input control following engagement of the direction input control to drive the belt in a selected drive direction.

A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A multi-mode wheelchair includes a frame, two front wheels, two rear wheels and two driver units. The frame includes an intermediate unit for interconnecting two side units. The intermediate unit is movable between a collapsed position and an extended position. The front wheels are connected to the side units. The rear wheels are connected to the side units. The driver units are connected to the side units. Each of the driver units includes a motor located in a corresponding one of the rear wheels and a brake operable to stop the motor. The driver units are located between the rear wheels. A distance between the driver units is larger than a breadth of a user when the intermediate unit is in the extended position.

A parking device for a motorized self-balancing wheelchair, connected to a wheelchair base by a pair of leverages is disclosed. Each of the leverages is connected by a proximal lever, to a shared gear driven by a gearmotor assembly that in turn is keyed, or constrained, to one of the leverages. Each proximal lever is articulated to a distal lever and each distal lever is connected by a guide to the base of the wheelchair and has a supporting foot to be supported on the ground. The shared gear has a pair of cogwheels meshing with one another and each of the cogwheels is integral to a proximal lever of the couple of leverages and has its own rotation axis, so that the operation of the gearmotor assembly puts the pair of cogwheels in simultaneous rotation to drive the leverages up or down.

A brake control device includes an operating switch and a control part. The operating switch is configured to be turned on when operated by a user. The operating switch is configured to be turned off when released from being operated by the user. The control part executes first brake processing for stopping the mobile object when the operating switch is switched off from on during traveling of a mobile object.

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus. A barrier assembly is secured to the upper frame by a tab which is received into a receiver formed in a head end of the frame.

Disclosed is a system for controlling a mobility device including a processor configured for a workflow process configured for filtering user commands based on a status of the mobility device and defining filtered commands. A mobility device command process is configured for issuing commands based on the filtered commands. The mobility device responds to the commands that are configured for controlling moving the mobility device.

A mobility impaired rehabilitation wheelchair having both a manual mode of operation and a motorized mode of operation for use by a wheelchair occupant in providing efficient and reliable leg exercising for improving circulation and providing muscular stimulation. The mobility impaired rehabilitation wheelchair has an electrical motor and shaft movement that is compact in nature for enabling the motorized mode of operation and the mechanical design provides the wheelchair occupant with a leaver to control movement and the ability to disconnect motion in the manual mode of operation.
