Abstract: A barrier configured to be located at a door a vehicle having a lift platform to enable an individual using a mobility device to exit and to enter an interior of the vehicle. The barrier includes a support base configured to be fixedly coupled to the vehicle. A first side and a second side each extend from the support base are spaced apart to define an access location for the individual using the mobility device. A barrier gate or a barrier plate include an entry position and a blocking position wherein, in at least one embodiment, movement of the lift platform moves the barrier plate from the entry position to the blocking position.

Abstract: A servo drive for driving an output shaft of a valve comprises a gear housing on which is mounted an electric driving motor which drives an eccentric through back gears. A planetary gear train includes an externally toothed inner gear engaged on the eccentric and driven thereby. The output shaft extends through the eccentric. An internally and an externally toothed outer gear has an internal gear portion and engageable with the external gear of the inner gear and has an outer gear portion engaged with a worm in a fixed self-locking manner. A plurality of wound bolts of equal diameter are arranged in spaced circumferential locations along a first circle around the center of the inner gear and they are spaced from each other by equal lengths of arc which protrude in one axial direction. A perforated disc connected to the output shaft has a disc portion oriented parallel to the inner gear and has a plurality of circumferentially spaced round holes in the same number of the number of bolts.
