A vehicle-sensitive mechanical contactor for tripping a restraint system in vehicles is provided with a spherical mass (12) which is held in a housing (10) such that it can move. A first contact spring (14) rests against its surface with a predetermined prestress. When the spherical mass (12) is in the quiescent position, the first contact spring (14) is at a predetermined distance (s) from a second contact spring (16). The second contact spring (16) can be deflected in order to combat the shock exerted by the spherical mass (12). A laminar spring (18) is furthermore frictionally engaged with the upper side of the spherical mass (12) in order additionally to damp its movements. With very small dimensions and very simple construction, the contactor ensures reliable, bounce-free contact-making and is suitable for restraint systems such as belt tighteners or airbag impact protection systems in vehicles. <IMAGE> |
