Abstract
A load supporting apparatus includes a base, and a platform adapted to support the load is pivotally supported on the base for movement between first and second positions, the platform becoming increasingly tilted as it moves from the first to the second position. A drive mechanism cooperable with the platform is provided for effecting pivotal movement thereof, and a control mechanism cooperable with the drive mechanism is provided for automatically actuating the drive mechanism to effect movement of the platform toward the second position in response to a shift in the distribution of the load thereon, thereby further tilting the platform and effecting a redistribution of the load. The control means is also responsive to the redistribution of the load caused by tilting of the platform for automatically deactuating the drive mechanism.
