Abstract
A collision detecting apparatus is provided which consists of a rotor and a first and a second contact spring. Upon collision, the rotor pushes the first contact spring to establish an electrical contact with the second contact spring. At least one of the first and second contact member is decreased in width from a base portion secured on a mount base to a contact portion, thereby decreasing the weight of the contact portion to avoid the contact chatter.
Claims7
A collision detecting apparatus comprising:
- a moving member moving when subjected to an impact of more than a given level arising from a collision with another object;
- and
- a first and a second contact member which are disposed on a mount base and extend with a given gap therebetween, said first contact member being brought by said moving member into contact with said second contact member to produce an electrical signal indicative thereof when said moving member undergoes the impact of more than the given level, at least one of said first and second contact members being made of a leaf spring which has a length including a base portion secured on the mount base and a contact portion for establishing a contact with the other of said first and second contact members, the base portion being smaller in width than the contact portion.
