A suspension for a vehicle is provided. The suspension includes, for example, a frame, at least one drive assembly and at least one caster pivot arm. The at least one drive assembly and the at least one caster pivot arm are pivotally connected to the frame such that the drive assembly and the front caster pivot arm are pivotable relative to one another.

A patient support apparatus supports a patient and comprises a litter. The litter comprises a patient support deck and extends longitudinally between first and second ends. A base is configured to support the litter and comprises a base lift mechanism configured to move the litter between lifted and lowered base positions. A side ramp is coupled to the patient support deck along the litter between the first and second ends and extends laterally away from the patient support deck to an engagement end. The side ramp is pivotable relative to the litter between first and second positions. In the first position, the side ramp is planar with or angled upwardly to extend above the patient support deck. In the second position, the side ramp is angled downwardly to extend below the patient support deck for contacting the floor surface with the engagement end when in the lowered base position.

A patient transfer apparatus is provided and includes a frame, a seat assembly coupled to the frame, and a track assembly coupled to the frame. The track assembly includes a moveable track for traversing stairs and a motor configured to drive the track. The apparatus further includes a control system. The control system includes a controller configured to control the motor and to adjust a speed of the apparatus based on an occupancy of the seat assembly upon traversing the stairs based on a current to the motor upon traversing stairs

A patient support apparatus for patients. The patient support apparatus comprises a base and a litter supported by the base. The patient support apparatus also comprises powered devices that perform one or more predetermined functions on the patient support apparatus. A user interface is employed to control the powered devices. The user interface is designed to enable caregivers to cause operation of the powered devices with fewer buttons, while retaining functionality in using powered devices.

A wheelchair having a chassis on which the following are arranged, opposite one another: at least one drive unit comprising a drive wheel and an electric drive system, a front wheel positioned on a front swivel arm, and a rear wheel. The drive unit and front swivel arm are arranged so as to pivot relative to the chassis in a vertical plane, and are coupled to one another by a first coupling and a second coupling member.

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 convertible wheelchair system, between a wheelchair configuration and an all-terrain configuration, is provided. Embodiments include a central frame aligned along a central longitudinal axis, the central frame having a front and back bar parallel to each other and orthogonal to the central longitudinal axis, paired side bars aligned with the central longitudinal axis, and paired wheel cages, aligned with the central longitudinal axis and attached to the front and back bars, each wheel cage supporting an axle and a wheel mounted thereon. The system further includes a forward beam alignable with the central longitudinal axis, configured to support a forward wheel, and reversibly attached to the front bar. The convertible wheelchair is in the all-terrain configuration when the forward beam is attached to the frame, and the wheelchair configuration when the forward beam is detached from the frame, the central frame thereby standing without the forward beam.
