Preferably, the universal scraper adapter is configured to couple the scraper with at least a top lock scraper arm, a side lock scraper arm and/or a U-hook scraper arm.

In this connection, a "firm coupling" is to be understood in particular as a connection between at least one body and a scraper, which is only used in a separation tool, such as a saw, in particular a mechanical saw, etc. and/or a chemical separation tool. Separation is possible with the aid of a medium such as a solvent or the like. "Arranged" is to be understood in particular as being specially configured, designed and/or equipped. "Providing the object for a specific function" is to be understood in particular that the object fulfills and/or performs this specific function in at least one state of use and/or operating state. "Releasable" is to be understood in particular as "detachable without destruction". In this context, "releasable coupling" is to be understood in particular as a connection between at least one connecting element and the wiper arm, which can be achieved without damage and preferably without tools by the operator, In particular, it is designed to be detachable by the end user and preferably subsequently reconnected.

In this context, "pivotably mounted" is to be understood in particular to mean that at least one connecting element has a bearing around at least one axis, in particular around exactly Possibility of movement in an axis that is movable through an angle of greater than 1°, preferably greater than 3° and particularly preferably greater than 5°. The at least one joint element and the at least one corresponding bearing element are designed to be coupleable to one another and preferably form a pivot bearing in the coupled state.

The at least one bearing element is at least partially provided for supporting the at least one joint element in the coupled state.

In this context, "releasable coupling" is to be understood in particular as a connection between at least one connecting element and at least one body which can be manipulated without destruction and preferably without tools.

At least one body is formed at least partially, preferably at least substantially completely, from plastic. The body is preferably connected to the wiper blade in a cohesive manner, in particular by ultrasonic welding. However, it is also conceivable that the body is firmly connected to the wiper blade in a form-fitting manner, in particular with a snap connection.

A high degree of operator friendliness and an advantageously wide range of applications can preferably be achieved by means of the embodiment according to the invention of the wiper adapter. In this way, in particular, the structural variants for different wiper arm types can be reduced and the production of the wiper blade adapter can be optimized.

Furthermore, it is proposed that the bearing recess has at least one bearing region which is designed to be partially open for introducing the at least one joint element in the radial direction. The bearing recess preferably has an at least substantially circular contour. However, it is also conceivable for the bearing recess to have an n-angled contour, n being in particular at least 5 counted. In this context, “in the radial direction” is to be understood in particular as looking from the geometric center point outwards, in particular straight to the contour of the bearing recess. In this context, "open in a partial manner" is to be understood in particular as: a bearing gap (viewed in at least one cross-section, in particular between 1° and 120°, preferably between 15° and 90° and Especially preferably in the range between 45° and 60° (viewed from the especially geometric center point outwards) there is a deviation from the especially at least substantially circular contour.

A particularly good and particularly advantageous slightly pivotable mounting of at least one joint element of the bearing unit can preferably be achieved by the embodiment according to the invention.

Furthermore, it is proposed that the open bearing region of the at least one bearing recess of the at least one bearing element has, at least in places, a width which is smaller than the width of the at least one joint element in the radial direction.

Proceed towards the base shape. The at least one detent element can preferably be formed at least partially from an elastically deformable material, for example in particular from an elastomer or other materials that appear to be meaningful to a person skilled in the art. In a particularly preferred embodiment, the detent element is designed to be elastically deflectable, in particular by means of suitable component geometry, for example a region with a small material thickness. A preferably secure coupling of at least one articulation element to at least one carrier element can thus be achieved in an advantageously simple manner.

In the following, only one of the two support elements 124 and one of the two articulation elements 122 are respectively illustrated for the two support elements 124 and the two articulation elements 122 of the support unit 120 . The articulation element 122 is designed at least partially as an articulation pin. The hinge element 122 is formed by a hinge pin. The articulation element 122 has a circular cross section.

The axes of symmetry of the bearing region 156 and of the securing region 158 each run parallel to the pivot axis 154 . The axes of symmetry of the bearing region 156 and of the securing region 158 each correspond to the pivot axis 154 .

The support element 124 is firmly connected to the connection element 118 . The carrier element 124 is connected to the connecting element 118 in a materially bonded manner. The carrier element 124 is formed in one piece with the connecting element 118 . The bearing element 124 of the bearing unit 120 is formed by a bearing recess 126 .

The bearing region 128 has a C-shaped contour. The open region 160 of the bearing region 128 has at least in sections a width which is smaller than the width of the articulation element 122 in the radial direction 132 . The width of the open region 160 of the bearing region 128 is smaller than the diameter of the cylindrical bearing region 156 of the joint element 122 .

The bearing recess 126 also has an insertion region 162 which is connected to the open region 160 of the bearing recess 126 and which has a width which is greater than the cylindrical bearing region 156 of the joint element 122 . diameter (Fig. 2b). The width of the insertion region 162 is always smaller as far as the width of the open region 160 of the bearing recess 126 .

The connecting element 118 and the body 116 are moved towards each other, so that the articulation element 122 is inserted into the bearing recess 126 via the insertion region 162 . Due to the narrowing of the bearing recess 126 in the insertion region 162 , the detent element 134 is deflected (during the movement of the articulation element 122 toward the region 160 which is configured to be open). In this case, the material of the connecting element 118 deforms elastically when the latching element 134 is deflected straight toward the slot 166 . After the joint element 122 has passed the locking element 134 , the locking element 134 is locked back and the joint element 122 is held against loss in the bearing region 128 of the bearing recess 126 and is rotatably mounted in the bearing recess 126 ( Figure 2d).

The bearing recess 226 includes a bearing region 228 and an insertion region 262 . The bearing region 228 is configured partially open for the insertion of the articulation element 222 in the radial direction 230 . The open region 260 of the bearing recess 226 is connected to the insertion region 262 and to the bearing region 228 . The width of the open region 260 of the bearing recess 226 is smaller than the width of the cylindrical joint element 222 in the radial direction 232 . The bearing recess 226 has a partially circular contour in the bearing region 228 . The bearing recess 226 has a C-shaped contour in the bearing region 228 . Insertion region 262 of bearing recess 226 is curved. On the side facing away from the bearing region 228 , the insertion region 262 has a width (viewed in the insertion direction) which is greater than the diameter of the joint element 222 . The width of the insertion region 262 is designed to be constantly reduced. For this purpose, the bearing recess 226 has a bevel 264 in the insertion region 262 . A further guide surface 268 adjoins said beveled surface 264 , which defines a curved section of the introduction region 262 .

The carrier element 224 includes a detent element 234 which is designed to be elastically deformable. The detent element 234 is arranged on the side of the open region 260 of the bearing recess 226 . The latching element 234 is formed in one piece with the connecting element 218 . The detent element 234 is arranged in the region of the edge 270 of the connecting element 218 and is designed to be elastically deflectable relative to the edge 270 of the connecting element 218 . The latching element 234 includes a latching lug. The detent nose projects into the open region 260 of the bearing recess 226 , so that the width of the open region 260 is smaller than the width of the articulation element 222 in the radial direction 232 . The snap-in nose is rounded on the tip.

When connecting element 218 is mounted on body 216 , connecting element 218 is positioned above body 216 in such a way that carrier element 224 of connecting element 218 is arranged above hinge element 222 of body 216 ( FIG. 3 c ). The connecting element 218 and the body 216 are moved towards each other, so that the articulation element 222 is inserted into the bearing recess 226 via the insertion region 262 . In this case, the articulation element 222 is first guided along the slope 264 and then, after a change in direction, along the guide surface 268 in the direction of the open region 260 of the bearing recess 226 . Due to the reduced configuration of the bearing recess 226 in the insertion region 262 , the detent element 234 is deflected (during the movement of the articulation element 222 toward the region 260 which is configured to be open). In this case, the material of the connecting element 218 deforms elastically when the latching element 234 is deflected straight towards the edge 270 of the connecting element 218 . After the joint element 222 has passed the locking element 234 , the locking element 234 is locked back and the joint element 222 is held against loss in the bearing region 228 of the bearing recess 226 and is rotatably mounted in the bearing recess 226 ( Figures 3d and 3e).

After the articulation element 322 has passed the latching element 334 , the articulation element 322 is held securely in the bearing region 328 of the bearing recess 326 and is mounted rotatably in the bearing recess 326 ( FIG. 4 c ).

The bearing recess 426 has a partially circular contour in the bearing region 428 . The bearing recess 426 has a C-shaped contour in the bearing region 428 . In the insertion region 462 the bearing recess 426 has a bevel 464 which runs from the open region 460 of the bearing region 428 straight to the edge 474 of the body 416 . The bevel 464 encloses an angle between 30° and 60° with the main direction of extension of the body 416 .

The carrier element 424 also includes a detent element 434 which is designed to be elastically deformable. The detent element 434 is arranged on the side of the open region 460 of the bearing recess 426 which is arranged opposite the bevel 464 of the insertion region 462 . The detent element 434 is formed in one piece with the body 416 . The detent element 434 is arranged in the region of the edge 474 of the body 416 and is designed to be elastically displaceable relative to the edge 474 of the body 416 . The latching element 434 includes a latching lug. The detent nose projects into the open region 460 of the bearing recess 426 , so that the width of the open region 460 is smaller than the width of the articulation element 422 in the radial direction 432 .

In this case, the articulation element 422 is guided at a bevel 464 of the insertion region 462 straight toward the open region 460 of the bearing recess 426 . Due to the reduced configuration of the bearing recess 426 in the insertion region 462 , the detent element 434 is deflected (during the movement of the articulation element 422 toward the region 460 which is configured to be open). In this case, the material of the body 416 deforms elastically when the locking element 434 is deflected straight towards the edge 474 of the body 416 . After the joint element 422 has passed the locking element 434 , the locking element 434 is locked back and the joint element 422 is held against loss in the bearing region 428 of the bearing recess 426 and is rotatably mounted in the bearing recess 426 ( Figures 5d and 5e).

The connecting element 518 and the body 516 are moved towards each other, so that the articulation element 522 is inserted into the bearing recess 526 via the insertion region 562 . In this case, the articulation element 522 is first guided along the slope 564 of the insertion region 562 and then after a change in direction along the guide surface 568 directly towards the open region 560 of the bearing recess 526 . Due to the reduced configuration of the bearing recess 526 in the insertion region 562 , the detent element 534 is deflected (during the movement of the articulation element 522 toward the region 560 which is configured to be open). In this case, the material of the body 516 deforms elastically when the latching element 534 is deflected straight towards the edge 574 of the body 516 .

The insertion direction of the securing recess 778 , along which the articulation element 722 is introduced into the securing recess 778 during installation, extends perpendicularly to the pivot axis 754 of the bearing unit 720 in the installed state and parallel to the securing recess 778 . Element 736 extends along movement direction 782 of wiper blade 12 . Movement direction 782 of securing element 736 runs parallel to spring rail longitudinal direction 50 of wiper blade 12 in the installed state of wiper blade adapter 710 . The securing element 736 includes at least one latching element 792 which is at least partially designed to be elastically deformable. The securing element 736 includes a detent element 792 . Detent elements 792 (viewed perpendicular to the insertion direction and perpendicular to the pivot axis 754 ) are arranged on the sides of the securing recess 778 . Detent element 792 is formed in one piece with securing element 736 . The detent element 792 has a detent nose which protrudes into the securing recess 778 so that the width of the securing recess 778 in the region of the detent element 792 is slightly smaller than the width of the articulation element 722 in the radial direction 732 .

The body 716 has at least one guide element 784 on its underside facing the wiper blade 12 in the installed state, which is provided for guiding the securing element 736 during a translational movement of the securing element 736 relative to the body 716 ( Figure 8b). The body 716 has two guide elements 784 . The securing element 736 has at least one guide element 786 which is provided to correspond to the guide element 784 of the body 716 . The securing element 736 has two guide elements 786 . Guide element 786 of securing element 736 and guide element 784 of body 716 engage each other in a form-fitting manner in the installed state and guide a translational movement of securing element 736 relative to body 716 in displacement direction 782 .

When connecting element 718 is mounted on body 716 , connecting element 718 is positioned above body 716 in such a way that joint element 722 of connecting element 718 is arranged above bearing recess 726 of body 716 . The connecting element 718 and the body 716 are moved towards each other, so that the articulation element 722 is inserted into the bearing recess 726 ( FIG. 8 c ). As soon as the articulation element 722 is positioned in the bearing recess 726 , the securing element 736 is displaced in the direction of movement 782 directly towards the body 716 of the wiper adapter 710 . In this case, the securing recess 778 is moved past the articulation element 722 ( FIG. 8 d ). The detent element 792 is deflected by a relatively straight further translational movement of the securing element 736 towards the body 716 . In this case, the material of the securing element 736 deforms elastically when the latching element 792 is deflected outwards. After the articulation element 722 has passed the detent element 792 , the detent element 792 snaps back and the articulation element 722 is held against loss and mounted rotatably in the bearing recess 726 and in the securing recess 778 ( FIG. 8 g ).

In the mounted state of the wiper adapter 710 , the body 716 forms a first stop surface 788 on the side facing away from the wiper 12 , against which the connecting element 718 abuts in the first stop position. Blocking. The first stop surface 788 encloses an angle of approximately 5° with the spring rail longitudinal direction 50 of the wiper blade 12 ( FIG. 81 ). In the installed state of the wiper adapter 710 , the securing element 736 forms a further stop surface 790 on the side facing away from the wiper 12 , against which the connecting element 718 rests in a further stop position. surface (Fig. 8e). The further stop surface 790 encloses an angle of approximately 12° with the spring rail longitudinal direction 50 of the wiper blade 12 . The first stop surface 788 of the body 716 and the further stop surface 790 of the securing element 736 form an obtuse angle in the mounted state of the wiper adapter 710 .
