The invention relates to a side overturning protecting and righting device and method and a passenger car with the side overturning protecting and righting device. The side overturning protecting and righting device comprises safety air bags located on the two sides of the car. Each safety air bag is provided with a fulcrum mechanism, wherein the fulcrum mechanism forms a fulcrum at the outward-extending end when the fulcrum mechanism is unfolded. According to the side overturning protecting and righting device, existing safety air bags are refitted into the safety air bags with the side overturning protection function and the car body righting function, and therefore side overturning righting is achieved. By means of the method, impact which is caused by righting to the car body can be relieved.
