Abstract

Automatic locking device for perfected safety belts, intended to retain a person in a vehicle and comprising a rotor shaft rotatably mounted within a wrap for winding the belt and a rotating rotor together with said shaft, disposed on the circumference of said at least one locking latch displaceable towards the outside in response to the centripetal forces that occur when the belt is removed, said latch being adapted to cooperate with one or more teeth disposed in the housing and with a two-arm blocking member, mounted on a horizontal shaft supported by a cover plate disposed substantially transversely to the rotor shaft, said blocking member having a first arm and a second arm, the second arm of which cooperates with an oscillating element hingedly suspended relative to the cover plate and adapted, when forces of a or deceleration exceeding a predetermined value, to oscillate the second arm in order to determine in the first arm an oscillation towards a releasing position with activation of the locking latch, in which position said latch is coupled to a locking tooth, in whose position said fastener is coupled to a locking tooth of the rotor with respect to the casing, a cam surface being formed after the oscillating movement of said oscillating element in a plane substantially parallel to that of the cover plate to produce said oscillating movement of the elements. Arms, the consistent characterizing aspect, in which the oscillating element is mounted at an upper point thereof in a freely articulated manner on said cover plate and on both sides of the second arm formed with the cam surfaces.
