  • Patent number: 5567001
    Abstract: An improved seat for a disabled driver or passenger of an automotive vehicle, is disclosed. The seat comprises a seat cushion including a stationary cushion component and a transport cushion component, the transport cushion component being constrained for movement in a path between a retracted position and an extended position. The transport cushion component is controlled by an operational system that includes a member having an extension member telescopically extendable from an end thereof and cable-drive means for moving the component between the retracted position and the extended position when under constant manual control. The manual actuator is accessible to constant manual control at the transport cushion and is recessed therein.

  • Patent number: 5147104
    Abstract: A seat for a disabled driver or passenger at the door of an automotive vehicle, the door moving between closed and open positions at a doorway through which the seat is accessible. The seat comprises a seat cushion including a stationary cushion component remote from the doorway and a transport cushion component adjacent to the doorway, the transport cushion component being constrained for movement in a path between a retracted position and an extended position. The transport cushion component, when in extended position, is located downwardly and outwardly of its retracted position. The transport cushion component is controlled by an operational system that includes a manual actuator for maintaining movement between the retracted position and the extended position when under constant manual control. The actuator is accessible to constant manual control at a handle bar that moves with the transport cushion.

  • Patent number: 5040832
    Abstract: A seat for disabled driver or passenger at the door of an automotive vehicle, the door moving between closed and open positions at a doorway through which the seat is accessible. The seat comprises a seat cushion including a stationary cushion component remote from the doorway and a lift cushion component adjacent to the doorway, the lift cushion component being constrained for movement in a path between a retracted position and an extended position. The lift cushion component, when in extended position, is located upwardly of its retracted position. The lift cushion component is controlled by an operational system that includes a manual actuator for maintaining movement between the retracted position and the extended position when under constant manual control. The actuator is accessible to constant manual control at the window sill of a front door of the automotive vehicle.
