Abstract
A self-leveling mechanism for a mobility device, the mobility device including a chassis configured to propel the mobility device on a surface, includes a leveling structure on which is mounted a user support for supporting a user of the mobility device. The leveling structure is connected to the chassis by a swivel connection that enables the leveling structure to swivel about the connection, and by two linearly displaceable connections that are laterally displaced from one another. Two linear actuators are each configured to displace one of the displaceable connections to adjust a distance between each displaceable connection and the chassis. A sensor for senses a tilt of the leveling structure and a controller is configured to operate the linear actuators in accordance with the sensed tilt.
