[0043] FIG. 9 shows a side view of a seat in a seating position with erected leg support; and

[0044] FIG. 10 shows the seat according to FIG. 9 in a perspective view.

[0045] The seat 1, which comprises a backrest 2, a seat element 3 and a leg support 4, is shown in FIG. 1. The backrest 2 is illustrated here in seating position, thus in upright position. The backrest is constructed to be pivotable about a first pivot axis X, wherein advantageously during pivotation in arrow direction P the seat element 3 remains at rest and is not deflected therewith. Advantageously, the seat element 3 remains in an unchanged, conveniently horizontal, position as illustrated in FIG. 1 regardless of the position of the backrest 2 or leg support 4.

[0046] The leg support 4 is shown here in an inclined seating position. This inclination is particularly comfortable for the seated child. The leg support 4 comprises a frame structure 11 as well as a foot support 12 arranged thereat to be displaceable. The free end of the foot support 12 is of bowl-shaped construction. Pivotation of the leg support 4 in arrow direction R takes place about the pivot axis S.

[0047] A projection 6 is fixedly arranged at the backrest 2 and extends downwardly along the backrest 2 in the longitudinal direction thereof. The projection 6 is formed to be longer than the backrest 2 and extends downwardly beyond the end thereof. The free end 8 of the projection 6 is illustrated to be projecting. As a result, an extension of the backrest 2 and thus also an extended lever action arises.

[0048] The telescopic connecting element 10 of multi-part construction is advantageously rotatably arranged at this free end 8 of the projection 6.

[0049] The backrest 2 additionally comprises a frame element 13, the limbs 14 of which are oriented to be inclined downwardly in the direction of the seat element 3. The ends of the limbs 14 are pivotably mounted on a bearing slide 21, which can be displaced in a gate guide 15 having the form of a segment of a circle. The ends of the limbs 14 are guided in a recess 16 of the boundary element 17. In addition, the ends of the limbs 14 advantageously have at least one nose-like projection 18 which is mechanically positively and/or frictionally coupled with the stepped profile 20 of the recess 16. In this example, the stepped profile 20 is of triple-stepped construction so that the backrest 2 apart from the seating position illustrated here can be brought via an intermediate position (FIG. 4) into the lying position (FIG. 6). Through use of the bearing slide 21 with the frame element 13 it is possible for the backrest 2 to be adjusted in angle of inclination by displacement of the bearing slide in the gate 15. The backrest in that case bears against the inner side of the frame element 13. Instead of this solution, a backrest can also be mounted in classic manner, i.e. pivotably attached to the seat element 3 by way of a detent bearing. Then a bracket of a roof or sunshade can also be fastened to the bearing slide 21.

[0050] If the backrest 2 in the seating position is subjected to application of a pressure force downwardly in arrow direction P, for example by raising the limb ends 14 and releasing the locking between projection 18 and stepped profile 20, then several movement sequences advantageously take place synchronously, thus simultaneously. Initially, the limb ends 18 describe at least partly an arc K within the recess 16. The backrest 2 is thereby pivoted about the pivot axis X thereof and the lever axis H upstream of the pivot axis X is guided in the direction of the seat element 3.

[0051] By virtue of this displacement of the lever axis H the telescopic connecting element 10 is guided towards the leg support 4 so that this is deflected upwardly in arrow direction R about the pivot axis S thereof. During this movement sequence the connecting element 10 remains unchanged in its length, but is guided in the direction of the seat element 3 so that the region B or the spacing between seat element 3 and connecting element 10 reduces. The seat element 3 remains unchanged in its original position.

[0052] A perspective illustration of the seat already described in FIG. 1 is shown in FIG. 2, so that the same components have the same reference numerals and for the sake of simplicity are not explained again here.

[0053] The perspective illustration shows that advantageously two projections 6 are arranged at the backrest 2 and extend downwardly, advantageously parallel to one another, at the outwardly disposed rear side of the backrest 2. The two projections 6 project beyond the backrest 2 so that free ends 8 of the projections 6 are formed.

[0054] In addition, it is advantageous to construct the telescopic connecting elements 10 to be detachable at the leg support 4, for example by means of hook-in openings, eyes or other snap mechanisms. This is obviously to be understood as non-limiting, so that it is also conceivable for the telescopic connecting elements 10 to be fixedly connected with, for example glued or welded to, the leg support 4.

[0055] The arrangement of two parallel telescopic connecting elements 10 additionally increases stability during the movement transformation and in the end settings of backrest and leg support, in which case the base 28 of the U-shaped connecting part of the connecting element increases the stability of the connecting elements. The two limbs 29 and 30 extend parallel to one another in the direction of the free ends 8 of the projections 6. Through this U-shaped arrangement the force at the time of the movement transformation is better distributed during pivotation of the backrest 2 and thus also facilitates deflection of the leg support 4 by a lower level of force. The lever axis H extends between the free ends 8 of the projections 6.

[0056] An intermediate position of the seat 1 is shown in FIG. 3. Here, as well, identical reference numerals correspond with identical components as in the previous figures. In this illustration the backrest 2 is deflected from the substantially vertical seating position shown in FIG. 1, so that the limb ends 14 are guided along the arc K in the recess 16 and the projection 18 forms, together with the second step of the stepped profile 20, a connection by mechanically positive and/or frictional couple.

[0057] At the same time, the deflection of the backrest 2 has the consequence that the free ends 8 of the projections 6 are similarly tilted, so that the telescopic connecting elements 10 transfer the prevailing pressure force to the leg support and this is deflected upwardly in arrow direction R about the pivot axis S. At the same time, deflection of the upstream lever axis H in the direction of the seat element 3 also takes place so that the region B below the seat element 3 and the connecting element 10 reduces.

[0058] A corresponding three-dimensional illustration is shown in FIG. 4, where, in particular, the circular movement along the recesses 16 of the respective element 17 is illustrated. The bearing slide 21 is displaceable by way of the gate guide 15 until it travels against the abutment 19 at the side wall of the seat element 3. The pivot bearing for the roof bracket lies outside the segment path of the side part.

[0059] The seat 1 is shown in the lying position in FIG. 5 and FIG. 7, wherein the leg support 4 is advantageously pivoted horizontally (FIG. 5) or at an inclination beyond the horizontal (FIG. 7) about the pivot axis S. The telescopic connecting elements 10 are in that case similarly arranged at an inclination and together with the seat element 3 and the free end 8 span a triangular area.

[0060] The backrest 2 is guided substantially planarly in rearward direction and thus offers a comfortable sleeping position for the child (not shown) present in the carriage.

[0061] The lever axis H is displaced far below the seat element 3. The projection 18 is locked at the last step so that further pivotation of the backrest 2 is prevented.

[0062] The corresponding seat 1 of FIG. 5 is shown in FIG. 6 in a perspective illustration, in which case it is evident here that, in particular, the frame element 13 or the limb ends 14 thereof is or are arranged in an end position at the stepped profile 20, where they act as a limitation for the pivotation.

[0063] The corresponding seat 1 of FIG. 7 is shown in a perspective illustration in FIG. 8, wherein it is evident here, in particular, that the frame element 13 or the limb ends 14 thereof is or are disposed in an end position at the stepped profile 20, where they act as a limitation for the pivotation.

[0064] FIG. 8 additionally shows the displaceable bowl-shaped foot support 12, which is displaceable in the direction of the arrow A relative to the leg support 4.

[0065] Finally, in FIG. 9 there is shown yet a further schematic side view of the seat 1, in which here the backrest 2 and the leg support 4 are illustrated in the decoupled state. In this case, the backrest 2 is arranged in the seating position and not deflected. By contrast thereto, the leg support 4 is disposed—pivoted about the pivot axis S—in the lying position.

[0066] This is advantageously made possible by provision of the telescopic connecting elements 10 on the one hand, since these are drawn out and extended in the length thereof, so that pivotation is made possible, in the case of application of tension force which accompanies pivotation of the backrest 2 into the seating position. For additional security the projection 18 engages the steps of the stepped profile in appropriate operative connection.

[0067] In addition, a detent element 24 is arranged on the pivot axis S. Advantageously, detent elements 32 of that kind are arranged on either side of the leg support 4. If pressure is now applied to the detent element 32, which in the simplest case is constructed as a pushbutton or as a rocker switch, then the deflection of the leg support into the lying position is released and causes free movement of the leg support 4, which is then returnable to the actual seating position.

[0068] During this return to the actual seating position the telescopic connecting elements 10 are loaded with pressure force and are reduced in the length L thereof so that the original initial seating position shown in FIG. 1 is achievable again at any time.

[0069] FIG. 10 shows the schematic side view, which is illustrated in FIG. 9, again in perspective, wherein here additionally a sunshade 34 and/or a carrying yoke is or are provided. Advantageously, the two are arranged to be pivotable about a further pivot axis Z.

[0070] All features disclosed in the application documents are claimed as significant to the invention insofar as they are new and inventive individually or in combination relative to the prior art.
