Human Factors; Procedure
Another mechanic and I completed a deferral on [the] aircraft; proceeded down the stairs to an electric cart positioned next to jet bridge stairs. We both entered the cart and attempted to leave area but the cart indicated a fault; and would not move. While trying to resolve fault; the jet bridge started to move toward us. Because the doors zip closed on cart; escape was impossible. We then both tried yelling and waving to both ramp personal (one was marshaller); the jet bridge continued to impact the vehicle which was now tipping over 60 degrees (one side window facing the ground the other the sky). As the vehicle was pushed over; the angle iron from the baggage chute was tearing through the door. This angle iron and the rest of the baggage chute prevented the cart from falling over completely on its side. The angle iron was also pressing against [my] passengers' leg through [the] door. Before the aircraft was pushed; another person noticed the situation and notified the others to reposition the jet bridge; which up-righted the vehicle. This could have resulted in MAJOR INJURY to a FATALITY. Both occupants were not physically injured but were traumatized and shaken. The vehicle did finally move after incident. This is a refilling of a report not properly addressed and no resolution was given.Suggested Resolution: Need to ensure area is clear prior to moving [the] jet bridge. I believe marshaller view was partially obscured by both [the] jet bridge stairs and air unit. This is not an excuse it just means more vigilance is necessary.
A Maintenance Technician reported that a jet bridge impacted a maintenance vehicle tipping it over.
