A collision impact detector (1) detects deceleration of a vehicle caused by its collision with another vehicle or an obstacle. A rotor (4) is rotatably supported on a shaft (3) and biased by a coil spring (5) in a direction opposite to a rotational direction in which the rotor is rotated by the deceleration. One axial end of the coil spring (5) is supported by a first support (6) integrally formed with the rotor (4), and the other axial end of the coil spring is supported by a second support (7) formed separately from the rotor. In this manner, a friction torque generated between the coil spring (5) and the second support (7) is eliminated, thereby considerably reducing a total friction torque associated with rotation of the rotor. The second support (7) may be formed either integrally with or separately from a housing (2) supporting the shaft (3).

A collision detecting apparatus (1) is provided which consists of a rotor (3) and a first (7) and a second (8) 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.

A deceleration impact detector for detecting a vehicle collision or the like is composed of a rotor (3) having an eccentric gravity center, a spring (4) biasing the rotor to its initial position, a cam (2) connected to rotor, and a pair of contacts consisting of a movable contact (5) and a stationary contact (6). The rotor (3) rotates together with the cam (2) when a deceleration exceeding a predetermined level is imposed on the rotor. The pair of contacts are closed by the cam thereby to generate an electrical signal to inflate an air-bag. The movable contact (5) is made of a resilient leaf spring, while the stationary contact (6) is made of a plate having a high rigidity, so that resonant vibrations of the stationary contact (6) otherwise caused by a high deceleration impact are avoided.
