Seat belt buckle signed detecting device and seat belt buckle

摘要

The buckle conclusion detection device 40 for the seat belt which detects the presence of the conclusion of the seatbelt, the printed circuit board the slider 42 which continues and, has common contact point with common contact point 41 which has normally-closed contact NC and normally open contact NO and common contact point COM and normally-closed contact NC COM or normally open contact NO COM. Common contact point COM is formed by the aspect 41of a one side of printed circuit board 41, normally-closed contact NC and normally open contact NO are formed to the other aspect 41b of printed circuit board 41. Because of this, the case where it changes with the normally-closed contact and the normally open contact the normally open contact making the surface distance between the normally-closed contact long time lag without increasing, it is possible to prevent the fact that it shorts in at these time.
