Definitions

  • the invention relates to a closure according to the preamble of patent claim 1.
  • the locking element has at its end enclosing the pivot axis a stop surface, via which a locking movement leading the locking element into its locking position is initiated when the tongue is inserted into the guide channel. Furthermore, a return spring is arranged between the locking element and the locking member, against the restoring force of which the actuating button transfers the locking element into the release position.
  • the return spring which is arranged between the locking element and the locking member, is provided as the second spring. Furthermore, only a relatively low torque is introduced into the locking element when the locking element moves into its locking position because the stop surface provided on the locking element is provided at the end at which the pivot axis of the locking element lies.
  • the object of the invention is therefore to provide a closure of the type mentioned, which has a simplified structure and in which the closing function is improved.
  • the stop surface via which the insertion movement of the tongue into the locking element for moving the locking element into its locking position is initiated, is provided at the end which is remote from the pivot axis of the locking element. This results in a large lever arm with which the insertion movement of the tongue is transmitted to the locking element.
  • the actuating lever transmitting the insertion movement of the tongue is supported on the displaceably mounted locking element, so that the insertion movement of the tongue is achieved for a synchronous movement of the locking element into its locking position and of the locking element into its locking position.
  • the spring force imparted by the ejector spring acts as a support when moving the locking element in the direction of its locking position.
  • the actuating lever is preferably designed as an angle lever, so that an effective transmission of the insertion movement of the tongue is achieved on the third stop surface on the locking element.
  • the tongue or the ejector pushed back by the tongue in the guide channel acts on one lever arm and the second lever arm, which is angled opposite, on the third stop surface on the locking element.
  • the actuating lever is pivoted about the axis formed on the locking element, the locking element is pivoted with its first stop surface in the direction of the guide channel to the point at which, after the insertion movement has ended, the engagement point comes to rest on the tongue at which the first stop surface of the locking element is in the locked position.
  • the first phase of the pivoting movement of the locking element is in the locking position by the actuating lever causes.
  • the locking element on the locking element comes into the plane in which the second stop surface lies on the locking element. Due to the force of the ejector spring transmitted to the locking element via the two-sided lever, the locking element is moved into its locking position until it bears against the second stop surface of the locking element, which is the final locking position of the locking element.
  • the locking element In the area in which it rests with the locking element in the locking position, the locking element is designed such that it rests with a positive fit on the second stop surface of the locking element. In adaptation to a rectilinear second stop surface of the locking element, the locking element in the area or in the areas with which it rests on the locking element in the locking position can also be designed with straight surfaces.
  • the locking element preferably has a square profile in this area.
  • the locking element on the carrier is guided against rotation about its longitudinal axis.
  • the locations of the locking element which bear on the carrier with sliding contact can have a positive fit with the carrier.
  • This area or these areas of the locking element can also have a square profile.
  • the two exemplary embodiments for a seat belt buckle shown in FIGS. 1 to 4 have a tongue 11 connected to a seat belt strap 19.
  • the tongue 11 can be inserted into a guide channel 2, which is delimited in a carrier formed by two plates 20 and 21 (FIGS. 3 and 4).
  • the locking element 1 is mounted at one end in a pivot axis 17 on the carrier 5.
  • a bearing pin 23 fastened in bearing bores 24 of the carrier 5 is used to form the pivot axis 17.
  • the bearing pin 23 is inserted through openings 25 at one end of the locking element 1 (FIG. 1).
  • the pivot axis 17 of the locking element 1 running parallel to the insertion plane of the guide channel 2 is formed.
  • projections 38 are formed on the locking element and are mounted in corresponding recesses 39 to form the pivot axis 17 on the carrier 5.
  • a first stop surface 8 extending transversely to the guide channel 2 is formed.
  • the tongue 11 bears against this stop surface 8 in the locking position (FIGS. 3 and 4).
  • a second stop surface 9 is provided on the locking element. In the locked position (FIGS. 3 and 4), this second stop surface extends parallel to the insertion direction or insertion plane of the guide channel 2. against the second stop surface 9 of the locking element 1 is in the locking position, a locking element 4. This locking element 4 is mounted on the carrier 5 in a slot guide 26 parallel to the insertion level of the guide channel 2 to and fro.
  • the locking element which is in the form of a pin, has a central region 27 with a round profile, in particular with a circular cross section. At both ends, the locking element 4 has a square profile 28.
  • the double-sided square profile 28 creates a positive contact or sliding guide in the elongated hole guide 26, which is provided on both sides in the carrier 5, in particular on the board 21, in side legs. This prevents the locking element 4 from rotating about its longitudinal axis during the movement between the release position (FIG. 2) and its locking position (FIGS. 3 and 4).
  • a form fit in the locking position is achieved by the one flat boundary surface of the respective square profile 28, which rests on the second rectilinear or flat second stop surface 9 of the locking element 1 (FIG. 5C).
  • the force of an ejector spring 3 acts on the central region 27 of the blocking element 4 via a two-armed lever 7 supported on the carrier 5 and a rod-shaped rigid motion transmission element 16.
  • the ejector spring 3 acts with its spring force in a known manner on an ejector 14 which is movable along the guide channel 2.
  • the ejector spring 3 is supported at one end (the right end in the figure) directly on a lever arm of the two-sided lever 7.
  • the ejector spring 3 is supported on a balancing mass 18 which is arranged between the ejector spring 3 and the one lever arm of the two-sided lever 7.
  • the balancing mass 18 is used in a known manner to secure the closure against shock in the event of excessive acceleration.
  • the two-sided lever 7 is pivotally mounted on the carrier 5 about an axis 29.
  • Bearing holes 30 on the side legs of the board 21 form the bearing points of the lever axis 29.
  • an actuating lever 12 is provided which is pivotably mounted on the locking element 4.
  • the actuating lever 12 is preferably pivotally mounted on the round profile of the central region 27.
  • the actuating lever 2 is designed as an angle lever with the lever arms 13 and 15.
  • the insertion movement of the tongue 11 into the guide channel 2 is used.
  • the ejector 14 is moved against the force of the ejector spring 3 (from left to right in FIGS. 2 to 4).
  • the direction of insertion is indicated in FIGS. 3 and 4 by an arrow 31.
  • the actuating lever 12 is pivoted counterclockwise from the position shown in FIGS. 2 and 5A about the longitudinal axis of the locking element 4.
  • the ejector 14 engages the lever arm 13 during its movement in the guide channel 2 and pivots it accordingly, as is shown in FIG. 5B.
  • the actuating lever 12 When the actuating lever 12 is pivoted counterclockwise, it presses with its lever arm 15 onto a third stop surface 10 of the locking element 1.
  • the third stop surface 10 like the first and second stop surfaces 8 and 9, lies at the end of the locking element 1 opposite the pivot axis 17. Between the force introduction point formed in the third stop surface 10, into which the insertion movement of the tongue is introduced into the locking element 1 via the actuating lever 12 is, and the pivot axis 17 of the locking element is thus formed a large lever arm.
  • the ejector spring 3 exerts a force F on the locking element 1 on the first stop surface 9, which force is directed in the opposite direction to the insertion direction 31. Since the pivot axis 17 is arranged offset with respect to the effective direction of the ejector spring 3 (FIG. 6), a resulting force component F2 acts on the locking element 1, which generates a moment on the locking element 1 in the direction of the release position. However, opening of the locking element 1 is prevented by the locking element 4 resting on the second stop surface 9 with its square profiles 28.
  • a closed force-locking chain supported on the carrier 5 is formed, which acts in two directions, namely in the direction of insertion (arrow 31) and opposite thereto in the direction of the force F, the ejector spring 14, the part of the locking element 1 containing the stop surfaces 8 and 9, the locking element 4, the rigid movement transmission element 16, the two-sided lever 7 and optionally the balancing mass 8 (embodiment of Figures 1 to 3).
  • This closed frictional chain ensures secure positioning of the individual parts, in particular the locking element 1 in the locking position.
  • the actuation button 6 In order to return the locking element 1 from the locking position to the release position, the actuation button 6 is shifted in the direction of insertion (arrow 31). The actuation button 6 is displaced against a spring 35 which is supported, for example, integrally with the support 5, and moves the locking element 4 from the locking position in FIGS. 2 to 5 to the right.
  • the ejector spring 3 When moving the locking element 4 along the slot guide 26, the ejector spring 3 is compressed via the two-sided lever 7 and exerts an increased force on the locking element 1 on the first stop surface 8 via the ejector 14, which generates an increased torque in the direction of the release position on the locking element 1.
  • the square profiles 28 of the locking element 4 are displaced into the recess 32, the locking element is pivoted toward the release position due to this torque.
  • This can be supported by an inclined ramp 36 formed on the locking element 1, which can come into engagement with the locking element 4, so that a movement on the locking element in the direction of its release position is also impressed or moved by the displacement movement of the locking element 4 from its locking position into the release position is initiated. Furthermore, an additional spring can be provided which is supported on the actuation button and on the locking element.
