7. The buckle tongue according to claim 1, wherein the blocking element is movable from the unloaded passage position into the loading position with a narrowing section along a contact surface of the tongue body, so that in the loading position the belt strap is in two-dimensional contact by a belt strap section both with the contact surface of the tongue body and with the narrowing section of the blocking element, wherein the narrowing section is covered, at least in the unloaded passage position of the blocking element, by the cover.

8. A buckle tongue with a tongue body extending in a plug-in direction, having a belt slot is formed in the tongue body transversely to the plug-in direction for guiding a belt strap through, comprising a blocking element arranged movably in the tongue body, wherein the belt strap is movable through the belt slot in an unloaded passage position of the blocking element and is at least inhibited in its mobility by the blocking element in a loading position brought about by a tensile force introduced into the belt strap, wherein the belt strap in a fastened state is deflected by the buckle tongue in the form of a loop, wherein a cover is provided at least on one side of the tongue body and the cover is arranged at least with a subsection below the belt slot, wherein the subsection of the cover arranged below the belt slot directly adjoins the belt slot and covers at least a part of the blocking element located in the unloaded passage position, wherein the blocking element is movable from the unloaded passage position into the loading position with a narrowing section along a contact surface of the tongue body, so that in the loading position the belt strap is in two-dimensional contact by a belt strap section both with the contact surface of the tongue body and with the narrowing section of the blocking element, wherein the narrowing section is covered, at least in the unloaded passage position of the blocking element, by the cover, and wherein at least in the loading position the tongue body with a region comprising the contact surface engages through at least one section of the blocking element.

Description

(1) The invention and the technical environment are explained below by way of example with reference to the figures. The following are shown schematically:

(2) FIG. 1: a partial exploded view of a belt tongue,

(3) FIG. 2: a locking element of the belt tongue,

(4) FIG. 3: a rear view of a cover of the belt tongue,

(5) FIG. 4: a perspective view of the belt tongue with mounted cover; and

(6) FIG. 5: a detailed view of another embodiment of a belt tongue.

(7) FIGS. 1 and 4 show a belt tongue 1 having a tongue body 3 which extends into an insertion direction 2 and which comprises a plate and an encapsulation. A belt slot 4 running crosswise to the insertion direction 2 is formed in the tongue body 3. A blocking element 5 shown individually in FIG. 2 is movably arranged in the tongue body 3.

(8) The blocking element 5 comprises a first part 12 and a second part 13 which are spaced apart by a recess 11. The belt, not shown, is guided through the recess 11. The blocking element 5 additionally comprises laterally projecting stop elements 15, wherein counter stop surfaces are formed in the encapsulation of the tongue body 3 with which the stop elements 15 of the blocking element come into contact in the loaded position. The blocking element 5 is rotatably mounted in the tongue body 3 by means of a torsion bar. When a tensile force is introduced into the belt in the buckled state, the force acting on the second part 13 from the belt causes the blocking element 5 to pivot, as a result of which the first part 12 of the blocking element 5 forming a narrowing section is moved along a contact surface 14 of the lock body 3, thereby forming a scissors-like sliding edge for the belt between the contact surface 14 and the first part 12 of the blocking element. The movement of the belt is at least inhibited, if not completely prevented, by this sliding edge.

(9) A cover 6 shown in detail in FIG. 3 can be attached to the tongue body 3. The cover 6 is U-shaped and has a section 7 and two legs 10 protruding therefrom. On a side facing the tongue body 3, the cover 6 has projections 8 which can be inserted into corresponding recesses 9 on the tongue body 3 for force-fitting fixing of the cover 6. As can be seen from FIG. 4, the section 7 adjoins the belt slot 4 directly, so that the first part 12 of the blocking element 5 is covered by the section 7. The legs 10 of the cover 6 extend laterally along the belt slot 4 and cover the stop elements 15. The legs 10 extend with their ends towards a top of the belt tongue 1, so that the surfaces of the ends face upwards.

(10) It can be seen from FIG. 5 that an opening 16 for inserting a torsion bar is formed in the encapsulation of the tongue body 3. The opening 16 can be closed by a closure 17 integrally molded onto the encapsulation of the tongue body 3. It would also be conceivable for an opening 16 in the encapsulation of the lock tongue 1 to be closed by first forming a collar around the opening 16, which collar is pressed into the opening 16 by means of a punch for the purpose of closing. It would also be conceivable for the opening 16 to be closed by a plug which is introduced into the opening 16. For this purpose, for example, a piece of a wire could be separated from a corresponding material and introduced into the opening.
