Abstract (en)
An electric door operator is provided for controlling the opening and closing of a door pivotally mounted to a door frame of a multi-passenger mass transit vehicle. The electric door operator comprises a pinion and an energy source for rotating or driving this pinion in opposite directions through opening and closing cycles of the door. A gear sector is also provided which is mounted for rotation in an opposite direction from the pinion. The gear sector is engageable with the pinion and capable of being driven by the pinion such that it rotates in one of an opening and closing direction upon rotation of the pinion. A shaft member having a first and second end is provided. The first end of the shaft member is secured to the gear sector and the second end of the shaft member is engageable with one of a base plate and a wall portion of the vehicle. A push bar is suspended from the gear sector for one of opening and closing the door upon rotation of the gear sector in one of the opening and closing directions. <IMAGE>
