[0054] The two plastic halves illustrated in FIG. 3 are assembled to form the cargo bike transport carrier illustrated in FIG. 2. For fixing and/or connecting the two halves, a connecting bracket made up of two bracket elements 78 is provided in an upper region. The two bracket elements are connected to corresponding connecting elements in the region of the parting plane. The parting plane is the front side of half the rear wall 56 and/or half the front wall 58 as well as half the bottom element 52 illustrated in FIG. 3. The two bracket elements 78 are fixedly connected and/or braced to each other such that they form a clamp in the upper region of the cargo bike transport carrier.

[0055] Further, for connecting the two plastic halves two connecting bars 80, 82 (FIG. 4) are provided. A connecting bar, which is a rear connecting bar as seen in the direction of travel 34, is arranged in a recess 84 (FIG. 3). The recess 84 is provided in an inwardly extending rib-shaped boss 86. On the opposite side, i.e. in the other half of the injection molded part, the arrangement is the same. The front connecting bar 80 is arranged in a recess 88 (FIG. 3). For bracing the two halves of the cargo bike transport carrier, the connecting bars 80, 82 comprise a boss configured as a head on one side, for example, wherein on the other side of the bars a nut is screwed on. Likewise, the two connecting bars can have an internal thread such that fixing can be effected from the outside in particular by fixing elements 90 in particular configured as screws (FIG. 2).

[0056] Inside the cargo bike transport carrier 50 not only cargo can be provided but also, according to the disclosure, seats 104 for children. Instead of a seat element 104 arranged in the front as seen in the direction of travel 34, a storage compartment can be inserted into the transport carrier 50. The storage container can be easily adjusted and/or suspended to the inside of the transport carrier between accommodation units.

[0057] According to the disclosure, in particular a plurality of seat elements 104, three in the illustrated embodiment, for example, are arranged in the cargo bike transport carrier. The seat elements 104 comprise a back portion 108 and a seat portion 110, as can in particular be seen in FIGS. 4 and 5. Further, a head portion 112 is provided. The seat portion 110 comprises connecting and/or fastening elements 114. They have loop-shaped or tubular ends through which the connecting bars 80, 82 pass. Thereby, a stable connection between the seat portions 110 and the connecting bars 80, 82 is realized, which connection is in particular suitable for good load transmission. The seat element 110 can be folded about the connecting bar 80, 82 in the direction indicated by an arrow 116. When the seat is folded up (FIG. 4), the interior of the cargo bike transport carrier can be used for accommodating other cargo.

[0058] The back portion 108 is fastened to the connecting bracket 78 via fastening elements 118 corresponding to the fastening elements 114. The connecting bracket 78 extends through the tubular bosses. In addition, the back portion 108 can also be fastened to the connecting bars 80, 82 via corresponding connecting elements.

[0059] The head portion 112 comprises a bracket 120 supporting the head portion 112. The head portion 112 is adapted to be displaced along the bracket 120 in the direction indicated by an arrow 122 for height adjustment. At its ends directed downwards in FIG. 6, the bracket comprises tubular or annular bosses. The connecting bracket 78 passes through them. The head portion 112 is adapted to be pivoted downwards about the connecting bracket, as indicated by an arrow 124.

[0060] In addition, in the illustrated exemplary embodiment of the seat elements 104, a safety belt is provided. This is a safety belt comprising two safety straps 126. The safety straps 126 are fixedly connected to the connecting bracket 78 on the one hand, and to the connecting bars 80, 82 on the other hand. Via a belt buckle 128 the two safety straps 126 are connected to each other, and via another belt 130 they are connected to the seat portion 110. Such an arrangement of the safety belt realizes a load transmission to the connecting bracket 78 and the connecting bars 80, 82.

[0061] In another embodiment of a seat element schematically illustrated in FIG. 7, similar or identical components are designated by the same reference numerals.

[0062] Here, too, the seat element 110 is of a foldable configuration, wherein a corresponding folding or pivoting of the seat element 110 is effected about a pivoting axis 132 in the back portion 108.

[0063] The essential difference of the seat element illustrated in FIG. 7 is the manner of fastening the seat element in the cargo bike transport carrier. For fastening purposes, two upper fastening elements 136 and a lower fastening element 138 are provided on a rear side 134 of the back portion 108. The two upper fastening elements 136 comprise screws. They are inserted in horizontal bores provided at the connecting brackets 78. Thereby, a fixed connection between the seat element 104 and the connecting brackets 78 is realized.

[0064] The lower connecting element is configured as a hook and comprises a downwardly directed opening 140. With the aid of the opening 140 it is possible to fit the lower fastening element 138 to a connecting bar 80, 82 from above. Thus, loads acting in the horizontal direction are transmitted via the lower fastening element 138.
