  • Patent number: 12584342
    Abstract: An apparatus for controlling bus doors (14, 16) that are arranged as a pair of doors that move in coordinated relation between door open positions and door closed positions, enables passengers to access an interior area (12) of a bus (10). The apparatus includes an actuator (28, 226). The actuator includes a drive lever (34, 228) that is selectively rotationally movable between rotational positions in which both of the doors are in the open positions and in the closed positions. Exemplary arrangements include at least one controller (128) that is operative to prevent the doors from causing damage to or from being damaged by engagement with obstructions. The controller further enables a bus driver or other authorized user to control access to the interior area of the bus using a wireless device (144).

  • Publication number: 20250146334
    Abstract: A latch (10,120,200) includes a rotatable jaw (18, 124, 204) that engages and holds a striker (32,128,210) in a latched position. A rotatable pawl (28, 132, 214) in an engaged position is operative to hold the jaw in the latched position. Movement of the pawl to a disengaged position enables the jaw to move to an unlatched position and to disengage the striker. The pawl is movable from the engaged position to the disengaged position through operation of either an electrical actuator (84, 152, 236) or through movement of an actuating end (26, 142, 224) of the pawl by a cable or similar mechanical connector (36, 246).
