Definitions

  • the invention relates to a lock for a motor vehicle seat belt system for receiving and locking an insertion tongue with a latch for fixing the tongue, which can be moved between an unlocking and a locking position, a spring-loaded ejector, which extends the tongue in the unlocking position of the bolt presses the lock housing and a likewise spring-loaded button which can be moved in the direction of insertion of the tongue, by means of which the bolt can be moved into its unlocked position and which is blocked by an acceleration acting on the lock in the opposite direction to the release stroke of the button.
  • Locks of this type are required for use together with so-called lock braces. If this lock tightener is triggered in an accident, the lock is accelerated towards the vehicle floor by the energy released and braked in its lowest position within a very short time. Depending on the construction, accelerations between 500 and 1000 g can act on the parts of the lock.
  • the inertia of the release button creates forces that tend to move the button to its open position. This releases the lock bolt and releases the lock tongue.
  • GB 21 04 141 A a lock is known, in the trigger button a second button is guided. This second button actuates a safety pin that holds the release button in the rest position in a stable position relative to the housing.
  • the locking pin moves into its release position and the release button is released.
  • this lock is not suitable for use with a lock tightener.
  • the second button first moves into its release position due to its inertia, thereby enabling the opening button of the release button.
  • a lever loaded with an inertial mass is provided, which, when triggered, tensions between its mounting and the slide button.
  • the release button with a shock absorber which is intended to prevent an opening movement of the button in the case of shock-like accelerations.
  • the object is achieved in that at least part of the key is additionally tiltable.
  • the key consists of a functional part and an actuating part. Both parts are preferably made in one piece and connected to one another by a film hinge. The mass of the actuating part is negligible compared to the mass of the functional part.
  • a plastic spring, possibly molded onto one of the two key parts, which counteracts a relative movement of the two parts to one another, must be coordinated so that when the lock is accelerated, both key parts move with certainty first, so that a relative movement of the actuating part opposite the functional part can be excluded. As a result, a locking element attached to the actuating part can come into engagement with an element fixed to the housing and a further movement of the whole Lock the button.
  • the actuating part is first moved relative to the functional part and the locking element is thereby brought into a position in which it cannot come into engagement with the element fixed to the housing if the entire key is moved further .
  • the button is made in one piece.
  • the key spring is not articulated in the middle of the key, but close to the side that faces the lock tongue.
  • the key is designed to allow limited tilting around this edge.
  • the center of gravity of the key is as far as possible from the tipping point in the direction of the opposite side of the key.
  • the grip surface of the key is shaped so that when it is actuated for the purpose of opening, a tilting movement first takes place around the articulation point of the key spring.
  • a locking element which is attached to the key is brought into a position in which it cannot come into engagement with an element fixed to the housing when the key is moved further.
  • the mass of the key becomes center of gravity pulled down in the tilted position and the locking element comes into engagement with the housing-fixed element, which results in the key being locked.
  • the pivot point of the key spring can also be shifted to the side facing away from the tongue.
  • the center of gravity of the button should be as directly as possible above the pivot point. The result is the same as in the previous example.
  • the grip surface of the key and the lock housing are designed in such a way that, when actuated for the purpose of opening the lock, only vertical pressure from above is possible, so that the key is only moved in translation. In this case, a locking element connected to the key does not come into engagement with an element fixed to the housing. However, if the lock is accelerated, the key first performs a tilting movement due to a center of mass that is not in the line of action of the key spring, so that the locking element can in turn come into engagement with the element fixed to the housing.
  • a button which consists of a functional part 1 and an actuating part 2. Both parts are articulated together via axis 3.
  • the locking element 5 is fastened, which is in the rest position shortly before engagement with the element 6 fixed to the housing.
  • the spring 4 is tuned so that when the actuating element 2 is pressed, it moves only about the axis 3 before the functional part 1 moves against the force of the spring 7.
  • the center of gravity 8 is advantageously in the middle of the functional part 1 and the center of mass 9 of the actuating part 2 is directly above the axis of rotation 3 Actuating part 2 only pivoted out the blocking element 5 to such an extent that it does not come into engagement with the element 6 fixed to the housing when the functional part 1 moves in the opening direction.
  • the button is made in one piece.
  • a housing-fixed stop 10 is provided to turn the key 1 ', in its rest position about the point 9, in the position shown. This is done by the force of the spring 7.
  • a pressure which is directed approximately perpendicular to this actuating surface 2 '.
  • the key 1 ' is brought into a position in which the key-fixed locking element 5' no longer comes into engagement with the housing-fixed element 6 'upon further actuation.
  • the button moves translationally in the opening direction tung continue.
  • the key 1 Since the housing-fixed stop 10 acts only in one direction on the key, the key 1 'under the action of acceleration forces, only by the pivot point 12 of the spring 7, a resistance. In the position of the center of gravity 8 'shown, the key 1' will move downwards in the tilted position shown in FIG. 2, so that the locking element 5 'comes into engagement with the element 6' fixed to the housing and thereby blocks a further opening movement of the key .
  • the key 1 ' is held by the spring 13' in its rest position.
  • a trigger pressure approximately perpendicular to the actuating surface 2 'acts with the correct dimensioning of the springs 13' and 7 no resulting tilting moment on the key 1 ', so that the entire opening stroke consists of a purely translational movement.
  • the articulation point 12 of the spring 7 acts as an abutment, so that when the center of gravity 8 'moves, corresponding to the acceleration forces, the key 1' is exerted a tilting moment and the locking element 5 'engages with the element 6' fixed to the housing is coming.
  • correct dimensioning of the center of gravity 8 'and the spring 13' must be taken into account here.
