Zusammenfassung: | A collision detecting apparatus comprising a sphere of magnetic material normally held stationary by the attractive force of a magnet and a switch adapted to be closed when said sphere of magnetic material is moved overcoming said attractive force by virtue of the force of a collision, wherein the attractive force of said magnet tends to be relatively large under the normal driving conditions of a vehicle, while said attractive force is made to be relatively small by a signal indicative of the occurrence of a collision, whereby the apparatus may not be operated by any noise produced while the vehicle is running, but is capable of positively coming into operation upon the occurrence of a collision. |
