DETAILED DESCRIPTION OF THE DRAWINGS

[0028] FIG. 1 shows a sample embodiment of the inventive vehicle pedal as an example.

[0029] The vehicle pedal 2 takes the form of what is known as a vertical pedal and features a first part 4 in the form of a pedal lever and a second part 5 in the form of a coupling element, where the second part 5 is only shown in part in FIG. 4. In its assembled state shown in FIG. 1, the first part 4 is connected in a force-transferring and articulated manner to the second part 5 of the vehicle pedal 2 by means of a connection element 6.

[0030] The connection element 6 takes the form of a single-piece plastic part and comprises an essentially rigid central section 8, a first connecting section 10 for connecting the connection element 6 with the first part 4 and a second connecting section 12 for connecting the connection element 6 with the second part 5, where the two connecting sections 10, 12 are formed at free ends of the central section 8 opposite to each other. The first connecting section 10 features four first latching elements 14, 16, 18 and 20 that are formed on the central section 8 to act as a spring and, when the connection element 6 is in the assembled state shown in FIGS. 1 and 4, form a latching connection together with the latching elements 22 and 24 of the first part 4 formed corresponding to the first latching elements 14, 16, 18 and 20. The first latching elements 14, 16, 18 and 20 of the connection element 6 are shown in FIGS. 3a, 3b and 4. The corresponding latching elements 22 and 24 of the first part 4 can be seen from FIG. 4.

[0031] The total of four first latching elements 14, 16, 18 and 20 of the connection element 6 form, in the assembled state of the connection element 6 shown in FIGS. 1 and 4, a latching connection as pairs in each case, namely firstly the first latching elements 14 and 16 and secondly the first latching elements 18 and 20, with a latching element 22, 24 of the first part 4 corresponding to each pair of first latching elements 14, 16 and 18, 20, where the latching element 22 with the first latching elements 14, 16 and the latching element 24 with the first latching element 18, 20 each interacts in a latching manner. See FIG. 4.

[0032] As can be seen from FIGS. 2, 3a, 3b and 4, the first latching elements 14, 16, 18 and 20 are formed opposite each other by each pair of first latching elements 14, 16 and 18, 20 on different latching arms 26, 28, 30 and 32 of the fist connecting section 10, where the first latching element 14 is formed on the latching arm 26, the first latching element 16 on latching arm 28, the fist latching element 18 on the latching arm 30 and the first latching element 20 on the latching arm 32, namely at the free end in each case.

[0033] Each pair of first latching elements 14, 16 and 18, 20 features an exterior latching element 14 and 20 and an interior first latching element 16 and 18, where the latching arms 28 and 30 of the two interior first latching elements 16 and 18 of the two pairs 14, 16 and 18, 20 are connected to each other to transmit force in the present sample embodiment. In this context, see FIGS. 2, 3a, 3b and 4.

[0034] Furthermore, the first latching elements 14, 16, 18 and 20 take the form of a barb. In this context, see in particular FIGS. 3a and 3b. Furthermore, the first latching elements 14, 16, 18 and 20 are designed to be hollow so that during the manufacture of the connection element 6 formed as a single-piece plastic part, for example as am injection molded plastic part no unwanted material accumulation occurs in the area of the latching elements 14, 16, 18 and 20. In this context, see in particular FIGS. 2 and 4.

[0035] The latching arms 26, 28, 30 and 32 of the first connecting section 10 are, in the disassembled state of the connection element 6 shown in FIGS. 2, 3a and 3b, essentially parallel to each other. In this context, see in particular FIGS. 3a and 3b.

[0036] Furthermore, each of the latching arms 26, 28, 30 and 32 extend from a base plate 34 of the central section 8 of the connection element 6, where the force-transferring connection of the base plate 34 is formed with the individual latching arms 26, 28, 30 and 32 depending on a previously specified latching property of the latching connection. In this context, see in particular FIGS. 2 and 3b from which it can be seen that the base plate 34 of the central section 8 is slotted, in the area of the two exterior latching arms 26 and 32 allocated to the first latching elements 14 and 20, in such a way that the two latching arms 26 and 32 each feature longer free lengths in comparison to the two interior latching arms 28 and 30 allocated to the first latching elements 16 and 18.

[0037] Correspondingly, the exterior latching arms 26 and 32 are stiffened to a lesser degree in comparison to the two interior latching arms 28 and 30 by the base plate 34 and are thus more flexible that the interior latching arms 28 and 30, that feature only a short free length. Nevertheless, it is also conceivable that the force-transferring connection of the base plate to the individual latching arms are formed depending on a previously specified latching property of the latching connection. Depending on the requirements in each individual case, a specialist will determine the force-transferring connection of the base plate with the individual latching arms.

[0038] To achieve a latching connection with the second part 5 of the vehicle pedal 2, the connection element 6 features in its second connecting section 12 a latching bracket 36, the interior contour of which takes the form of an arc. The latching bracket 36 forms, together with a latching element 37 of the second part 5 designed to correspond to it, namely a latching bolt 37, a latching connection in the assembled state of the connection element 6. The latching bolt 37 is shown only in FIG. 4.

[0039] In the following, the functioning of the inventive vehicle pedal and the inventive connection element according to the present sample embodiments are explained on the basis of FIGS. 1, 2, 3a, 3b, 4, 5a and 5b.

[0040] The connection element 6 is initially in its disassembled state as show in FIGS. 2, 3a and 3b in which the connection element 6 is not connected in a latching manner with the first part 4 and the second part 5 of the vehicle pedal 2.

[0041] When converting the connection element 6 from its disassembled state into its assembled state shown in FIGS. 1 and 4 in which the connection element 6 is connected in a latching manner with the first part 4 and the second part 5 of the vehicle pedal 2, the connection element 6 is initially latched using the latching bracket 36 of the second connecting section 12 to the corresponding latching bolt 37 and the second part 5 and, in the image plane of FIG. 1, and inserted from bottom to top through an aperture (not shown) in a housing 38 of the vehicle pedal 2.

[0042] The first part 4 of the vehicle pedal 2 in the form of a pedal lever is connected to the housing 38 in a pivotable manner using, for example, a film hinge 42 formed on the pedal lever 4 and inserted in a groove 40 of the housing 38. The pedal lever 4, i.e. the first part 4, is swiveled around the film hinge 42 in the direction of the connection element 6 that protrudes with its first connecting section 10 from the aperture of the housing 38, such that the first latching elements 14, 16, 18 and 20 of the connection element 6 likewise form a latching connection together with the corresponding latching elements 22 and 24 of the first part 4. See also FIG. 4. Such conversion of the connection element 6 from its disassembled state into its assembled state is simplified by the fact that the first latching elements 14, 16, 18 and 20 each take the form of a barb. The first part 4 is now connected with the second part 5 of the vehicle pedal 2 such as to transmit force by means of the connection element 6.

[0043] An additional simplification for converting the inventive connection element from its disassembled state into its assembled state is, for example, made possible by the fact that corresponding lead-in chamfers are formed or arranged at the first part of the inventive vehicle pedal to the first connecting section of the connection element in order to guide in this way the first connecting section of the connection element when converting the connection element from its disassembled state into its assembled state. This makes blind mounting of the connection element possible when making the latching connection between the connection element on the one hand and the first part on the other hand.

[0044] As can be seen from FIG. 4, the two pairs of first latching elements 14, 16 and 18, 20 each encompass one of the two latching elements 22 and 24 of the first part 4, namely the two first latching elements 14, 16 encompass in the assembled state the latching element 22 and the two first latching elements 18, 20 encompass, in the assembled state, the latching element 24. Correspondingly, a secure force transmission connection is ensured between the connection element 6 on the one hand and the first part 4 on the other hand, even under adverse ambient conditions, such as with ambient temperatures in the temperature range at which the plastic from which the connection element 6 is manufactured starts to soften.

[0045] Due to the latching arms 28 and 30 connected to each other to transmit force of the two interior latching elements 16 and 18, it is possible to create a very rigid and thus very dimensionally stable latching connection between connection element 6 on the one hand and the first part 4 on the other hand. Such dimensional stability is increased in the present sample embodiment by the fact that force-transferring connections between the base plate 34 of the central section 8 and the two interior latching arms 28 and 30 extending into the range of the first latching elements 16 and 18 to such an extent that the latching arms 28 and 30 merely feature a short free length. In this context, see in particular FIG. 2.

[0046] FIGS. 5a and 5b show a sample embodiment of the inventive connection element as an example. Components that are identical or have the same effect have been given the same reference numbers in the Figures. Furthermore, the second sample embodiment is explained merely to the extent of the differences to the first sample embodiment of the inventive connection element. In all other respects, reference is made to the embodiments above.

[0047] In contrast to the first sample embodiment of the inventive connection element 6 explained above, the two interior latching arms 28 and 30 with the two interior first latching elements 16 and 18 are not connected to each other to transmit force. See FIGS. 5a and 5b. Instead, the two latching arms 28 and 30 are not connected to each other in the range of the two first latching elements 16 and 18. Correspondingly, the latching arms 28 and 30 with the first latching elements 16 and 18 feature a greater degree of flexibility in comparison to the first sample embodiment of the connection element 6, such that this embodiment of the connection element 6 fulfills other demands on the latching properties of the latching connection between the connection element 6 of the second sample embodiment and the first part 4 of the vehicle pedal 2.

[0048] In all other respects, the connection element 6 of the second sample embodiment corresponds to the connection element 6 of the first sample embodiment. The same is true for the way in which it functions. Correspondingly, the connection element 6 according to the second sample embodiment can be used in a similar manner to the above explanations on the first sample embodiment regarding the vehicle pedal 2 according to the above sample embodiment.

[0049] The invention is not limited to the present sample embodiments. This means that the invention can also be deployed advantageously in other kinds of vehicle pedals. For example, use with vehicle pedals designed as what are known as hanging pedals is also conceivable.

[0050] Furthermore, it would be possible with other embodiments of the invention that the second connecting section is designed in line with the first connecting section. Correspondingly, the second connecting section could be designed identically to the first connecting section, for example according to the sample embodiments explained above. It is also conceivable that the latching connection formed by the first connecting section and the first part is designed as an articulated connection.
