A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure. A track having a belt is attached to the support structure and is arranged for selective operation between: a retracted position, and a deployed position to engage stairs. A drive system with a motor is disposed in rotational communication with the belt to control movement along stairs in the deployed position. A user interface us arranged for engagement to selectively adjust operation of the drive system between: an active state for controlling movement of the belt with the motor, and an inactive state. A braking controller is configured to sense movement of the belt in the inactive state, and to control the motor to limit movement of the belt in the inactive state to effect corresponding limited movement of the patient transport apparatus along stairs.

A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.

A mobility device, including a base, a first omnidirectional wheel mounted at a first side of a forward portion of the base to rotate about a first axis, a second omnidirectional wheel mounted at a second side of the forward portion of the base to rotate about the first axis, a third wheel mounted at a rearward portion of the base to rotate about a second axis, a drive system to move the first omnidirectional wheel, the second omnidirectional wheel, and the third wheel according to input received indicating a desired motion of the mobility device, a seat for a user of the mobility device, and a linear actuator coupling the seat to the base to drive the adjustable seat in a vertical direction according to the input received indicating the desired motion of the mobility device.

A wheelchair braking system having a brake control mechanism, having a mounting member, an operation mechanism, and a link mechanism, a first braking circuit capable of applying a braking force to a first wheel, and a second braking circuit capable of applying a braking force to a second wheel.

Disclosed is a Wheelchair Electric Mobility Attachment including a rear wheels chassis functionally connected to a front chassis fork, for positioning two or more rear wheels of the mobility attachment, as part of a wheelchair connection scheme, at a position behind (further back from) the axle of the rear wheels of the wheelchair to which said attachment is being connected.

A mobility device, including a base, a first omnidirectional wheel mounted at a first side of a forward portion of the base to rotate about a first axis, a second omnidirectional wheel mounted at a second side of the forward portion of the base to rotate about the first axis, a third wheel mounted at a rearward portion of the base to rotate about a second axis, a drive system to move the first omnidirectional wheel, the second omnidirectional wheel, and the third wheel according to input received indicating a desired motion of the mobility device, a seat for a user of the mobility device, and a linear actuator coupling the seat to the base to drive the adjustable seat in a vertical direction according to the input received indicating the desired motion of the mobility device.
