Abstract
A vehicle includes a door frame coupled to a vehicle frame at a hinge. A door operating mechanism is coupled to the door and vehicle frames for applying rotational force to the door frame about the hinge. The door operating mechanism including external cogs of an inner gear that mesh with inner cogs of an outer gear and a single oblong bearing that biases the inner gear in partial engagement with the outer gear.

12. A vehicle comprising:
-
a motor coupled to a gear-reduction interface; and an oblong bearing of the gear-reduction interface that slidably rotates within a flexible spline and operates in a meshing engagement within a circular spline, wherein the motor operates the oblong bearing to deliver a rotational force of the motor to a hinge plate via the flexible spline. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A hinge assembly for a vehicle door comprising:
-
a motor coupled to a door frame and adapted to apply a rotational force thereto relative to a vehicle frame; an oblong bearing rotationally coupled to the motor; a flexible inner gear having an interior surface that receives at least a portion of the oblong bearing; a rigid outer gear having inner cogs that mesh with external cogs of the flexible inner gear, wherein rotation of the oblong bearing meshes the external cogs with the inner cogs resulting in rotation of the flexible inner gear relative to the rigid outer gear, wherein the flexible inner gear is coupled with a hinge plate that is attached to the vehicle frame. - View Dependent Claims (20)
