No Fault Accident, that is not a direct result of an action on anybody's part
Every day from May through September in each year between 1990-2010, there were an average of 20 injuries by amusement park guests under 18 years old that required hospitalization.
In 2011, 1,204 people were injured at 400 amusement parks, according to the IAAPA.
Florida
All of Florida's major parks—which include the Walt Disney World Resort, SeaWorld Orlando, Universal Orlando, and Busch Gardens Tampa Bay—report quarterly details surrounding accidents and other incidents at their parks. A requirement for these reported incidents is that they be fatal incidents, or that the injured person had required an overnight hospital visit. Four examples of the types of incidents that have been reported to Florida's Bureau of Fair Rides Inspection are listed here: From 2004 through 2009, the Orlando-area attractions that attracted the most guest lawsuits were:

Injuries to children
Approximately 4,400 children are hurt each year on amusement park rides, but only 1.5% of those injuries are serious enough to require hospitalization. Between 1990 and 2000, around 82,000 children under 18 were taken to emergency rooms after suffering injuries from amusement park rides. An additional 11,000 suffered injuries on rides outside amusement parks, such as those found at local malls, restaurants, or arcades. Of those reported 82,000 incidents, 34% occurred at locations where the rides were considered permanent, 29% happened on temporary attractions, and 25% were not categorized. Girls were injured more often than boys. The most frequent injuries were to the head, neck, arms, face, and legs. Most injuries reported appeared to be due to improper restraints or padding, or were caused by the child falling in, on, off, or against the ride.
