Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Further features and details of the invention will be better understood from the following specification which is provided by way of a non-restricting example as well as from the annexed drawing, wherein:

[0025] FIG. 1 is a schematic side view of a sitting structure for children, fixed to a bicycle, according to a first embodiment of the invention;

[0026] FIG. 2 is a schematic side view of a sitting structure, according to a second embodiment of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] With reference to the annexed FIG. 1, reference number 10 denotes a sitting structure with a child seat fixed to a bicycle B for adults.

[0028] The sitting structure 10 includes a frame 12 and a child seat 14, fixed to the frame 12 rigidly.

[0029] In particular, the frame 12 includes a base structure 16 to which the child seat 14 is fixed and is facing the back of the bicycle, as it appears from FIG. 1.

[0030] A bracket 18 is fixed below the base structure 16 and develops perpendicularly to the base structure 16.

[0031] Besides, the bracket 18 has a lower end which is fixed by means of a connection device to the frame of the bicycle B in correspondence of the rear hub M.

[0032] The coupling of the bracket 18 to the base structure 16 is ensured also by an oblique bar 20, the ends of the bar being welded to the bracket 18 and the base structure 16, respectively.

[0033] A first hinge 22 is fixed to the front end of the base structure 16 and connects the base structure to an arm 24 so that it is possible to vary the inclination of it.

[0034] The same arm 24 is fixed in a removable way to the crosspiece T of the bicycle B. The crosspiece T extends from the rear hub M to the saddle. The releasable fixing of the arm 24 to the crosspiece T is obtained by means of a clamping system 26.

[0035] A second hinge 28 is fixed to the rear end of the base structure 16, the arm 24 being fixable, in case, to said second hinge.

[0036] In fact, as shown in FIG. 1, the child sitting on the child seat 14 is facing the rear part of the bicycle and, therefore, can see all around without having any obstacle in front of him.

[0037] In case the child needs to perceive the presence of the adult who is driving the bicycle, the sitting structure 10 can be removed from the bicycle B by releasing the connecting device of the bracket 18 from the hub M and releasing the clamping system 26 from the crosspiece T of the bicycle B.

[0038] Once the arm 24 has been removed from the first hinge 22, the arm 24 is fixed to the second hinge 28 and then, the entire sitting structure 10 is rotated 180 degrees and is mounted on the bicycle B by means of the connecting device and the clamping system 26.

[0039] In this way, the child seat 14 is now turned toward the front part of the bicycle and the child is in contact, even visually, with the adult who is driving the bicycle B.

[0040] Besides, the possibility of rotating the arm 24 with respect to the base structure 16 allows to fix the sitting structure 10 to every bicycle for adults, regardless of the size of the bicycle B and the inclination of the crosspiece T.

[0041] According to a variant of the invention as shown in FIG. 2, a sitting structure 110 for children, fixable to a bicycle for adults, comprises a child seat 114, fixed to a frame 112, which corresponds to the frame 12 previously described for the sitting structure 10, and includes corresponding elements denoted by the same reference numbers increased by a hundred.

[0042] However, unlike that, in addition to feet supports 130 and side walls 132 preventing the legs of the child from inserting dangerously among the spokes of the rear wheel of the bicycle, the child seat 114 comprises also a particularly shaped back.

[0043] In fact, the back of the child seat 114 includes a first lower cavity 134 on which the back of the child can comfortably rest, as well as a second upper cavity 136 on which the back of the adult, who drives the bicycle on which the sitting structure 110 is fixed, can rest.

[0044] A technician of this sector can make changes or variants that are to be considered as included in the scope of protection of the present invention.

[0045] For example, the bracket for fixing the base structure to the wheel hub of the bicycle can be double so as to form a kind of fork astride of the rear wheel.

[0046] Besides, the arm that connects the base structure 16 to the crosspiece T of the bicycle B can be telescopic.
