PURPOSE: To provide a vehicle sensitive mechanical contactor for activating a restraining system in vehicles. CONSTITUTION: A contactor is provided with a mass ball 12 movably accommodated in a housing 10. A first contact spring 14 bears on the surface of the ball under prescribed bias. In the rest position of the ball 12, the spring 14 is at a prescribed distance (s) from a second contact spring 16. The spring 16 is deflectable for dampening the impact exerted by the ball 12. Furthermore, a spring blade 18 is in frictional engagement with the upper side of the ball 12 to additionally dampen the movement thereof. With extremely small dimensions and very simple construction, the contactor ensures a reliable bounce- free contacting and is suitable for restraining systems in vehicles, such as belt pretensioner or airbag impact protection system. |
