ABSTRACT:
An emergency escape tool is proposed for escaping from a car when an accident happens. Scissors for cutting a seat belt and a spike are provided. The spike is held at and retractably protrudes from a handle of the scissors. A tip of the spike is pressed against a window glass. A spike driver is housed in the handle. The spike driver usually urges the spike in the protruding direction. When the spike pressed against the window is displaced inwardly, the spike driver accumulates a compression force corresponding to the displacement. According to the accumulated compression force, the spike is promptly pressed toward the protruding direction so as to break the window glass.
