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, wherein said. 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 self-balancing vehicle comprising two axially spaced wheels (3, 4) mounted on a main body (2), an electric drive coupled to at least one wheel (3, 4), control means adapted to maintain the vehicle in balance by controlling the drive, a receptable for carrying and conveying a load, the vehicle having an adjustment mechanism (7) for linear displacement of the receptable arranged so that the receptable is adjustable by the linear displacement both along the longitudinal axis and along the vertical axis of the vehicle.

Methods, apparatus, systems and articles of manufacture to provide an improved mobility vehicle are disclosed. An example vehicle includes a sensor positioned with respect to a seat to detect pressure by a user with respect to the sensor and to generate a signal corresponding to the pressure; and a processor to convert the signal into a control command for a powertrain to move the vehicle.

A motorized wheelchair chassis includes a frame assembly having a first frame element that supports first and second caster wheels at an end of the first frame element. The first frame element is designed to support a seat assembly, a battery support assembly secured to an underside of the frame assembly, at least one battery, first and second power drive assemblies disposed on lateral sides of the battery support assembly, and first and second drive wheels driven by the first and second power drive assemblies, respectively. The frame assembly further comprises a second frame element that is secured to the battery support assembly. The first frame element is supported onto the second frame element via a coupling structure comprising a ball-joint bearing permitting relative movement of the first frame element with respect to the second frame element in more than two degrees of freedom within a limited range of movement.

Embodiments of a suspension for a vehicle is provided. The suspension includes, for example, a frame and a locking assembly. The locking assembly inhibits tipping of a frame of the vehicle when tipping of the frame is detected.
