1. Apparatus operative to provide emergency egress from an interior area of a bus, wherein the interior area of the bus is bounded on a lower side by a bus floor,
wherein the bus includes a bus body having an emergency exit opening that is closable by an emergency exit door, wherein the emergency exit door is openable from at least one of the interior area or an exterior area of the bus, wherein the emergency exit door is changeable between a latched closed condition in which the emergency exit door is held in a closed position closing the emergency exit opening, and an openable condition in which the emergency exit door is changeable between the closed position and an open position in which at least a portion of the door is movable away from the emergency exit opening,
the apparatus comprising:
at least one horizontal hinge, wherein the hinge is in operative connection with each of the bus body and the emergency exit door,
wherein the at least one horizontal hinge is operative to enable the emergency exit door when in the openable condition to movably rotate in operatively engaged connection with the bus body through the at least one hinge about an axis such that at least a portion of the emergency exit door moves vertically down and outwardly away from the emergency exit opening to a vertical level that is at least as low as the bus floor,
a ramp, wherein the ramp is movably mounted in operative connection with the emergency exit door,
wherein in the open position of the emergency exit door the ramp is extendable between the emergency exit door and ground,
whereby with the emergency exit door in the open position and in an extended position of the ramp, persons in the interior area are enabled to traverse the emergency exit door and the ramp to reach the ground.
