Child seat for attaching to a motor vehicle seeat

Abstract

The invention relates to a child seat for attaching to a motor vehicle seat, comprising a seat element as well as at least one support leg for supporting the child seat on a ground surface, in particular the footwell of the motor vehicle, wherein a display device is provided that is designed to display a ground contact of the support leg with the ground surface, in particular footwell, wherein the support leg has at least one upper telescopic section and a lower telescopic section, which can be moved against one another for lengthening and shortening the support leg, wherein an operative connection is present between the lower telescopic section and the display device, which is designed such that a shifting of the lower section in relation to the upper section leads to a releasing of the display device due to a ground contact of a support leg end.

20. The child seat of claim 19, further comprising: an operative connection including the locking device located between the lower section and the display device, wherein the operative connection causes the display device to be released by a shifting of the lower section in relation to the upper section; wherein the lower section and the upper section are securable in a selectable fixed relative position with the locking device.

Description

(1) The invention will be described below with reference to an embodiment which is explained in more detail with reference to the figures, wherein:

(2) FIG. 1 shows a section of the support leg in a schematic sectional view, in a locked state;

(3) FIG. 2 shows a sectional view according to FIG. 1 after ground contact;

(4) FIG. 3 shows a child seat according to the invention in a side view.

(5) In the following description, the same reference numerals are used for identical and equivalent parts.

(6) FIG. 1 shows a section of a support leg with an upper section 10 and a lower section 11. The upper section 10 is closer to a seat surface (not shown) of the child seat. The lower section 11 is closer to a foot (not shown) of the support leg.

(7) The telescopic support leg comprises in the present case exactly the two sections 10, 11 which are telescopically displaceable against each other. However, it is not excluded that further (possibly telescopically displaceable) sections are provided.

(8) The lower section 11 is guided within the upper section 10 (in an overlapping area).

(9) A locking device 12 comprises a base part 14 and a locking pin 13. In the locked state of the support leg shown in FIGS. 1 and 2 (but also in principle in the unlocked state), the locking device 12 can move relative to the upper section 10, namely by a distance 15, which is defined by a recess (slot) 16. In the locked state in FIGS. 1 and 2, the locking pin 13 engages positively in a recess 17 (a plurality of recesses 17) of the lower section, so that the lower section 11 cannot move relative to the locking device. A spring 18 causes that in an unloaded state of the support leg (as shown in FIG. 1), the locking device 12 is urged in the downward direction together with the lower section 11. In this context, it should be noted that the spring 18 shown in FIGS. 1 and 2 is shown purely schematically and in particular the (in FIGS. 1 and 2) upper end of the spring 18 is positioned equal to a stop 19. In other words, the spring 18 acts between the stop 19 fixedly attached to the upper section 10 and the locking means 12. An upper end of the spring may abut, for example, (inside) an upper end 25 of the stop 19 (both in FIG. 1 as well as in FIG. 2). The stop 19 is fixedly connected to the upper section.

(10) Now, when a ground contact of the support leg takes place, it results in a (pressure) force which presses the lower section or the locking device 12 against the spring force in the upward direction, so that the position in FIG. 2 is reached.

(11) The locking device 12 is connected to a rod 20, whose upper end (not shown in FIGS. 1 and 2) is in turn connected to a display device (indirectly or directly) or itself forms a display device. For example, it is conceivable that an upper end of the rod 20 protrudes from an opening (when the position shown in FIG. 2 is present) or disappears within an opening (when the position shown in FIG. 1 is present). Alternatively, it is also possible for an upper end of the rod 20 to transfer a mechanical display device to a first position when the position shown in FIG. 2 is present and to a second position when the position shown in FIG. 1 is present. For example, the display device could then make a green area visible if there is ground contact according to FIG. 2 or a red area if such ground contact is not present.

(12) Guide parts 21 allow efficient guidance of the lower section 11 within the upper section 10. In this case, the wide distance between these guide parts is exploited from each other, on the one hand to allow reliable adjustment of the leg length and on the other hand to be able to reliably indicate a ground contact. Wobbling or tilting is thereby avoided (or at least minimized) when the display device is triggered.

(13) The locking pin 13 is displaceable so that it is either engaged only with the recess 16 (unlocked position) or (as shown in FIGS. 1 and 2) is both in connection with the recess 16 of the upper section 10 and is introduced into one of the recesses 17 of the lower section 11. For the corresponding displacement of the locking pin 13, customary devices may be provided for this purpose (which devices are not recognizable in detail in the present case). For example, a (possibly spring-loaded) operating knob 22 and/or a pulling device can contribute to this, which is indicated by the reference numeral 23 and optionally brings the locking pin by pulling, for example, to the unlocked position as a result of a displacement (e.g. carried out by the operating knob), and/or a geometry of the locking pin 13, e.g. an inclined surface 24.

(14) In FIG. 3, the entire child seat, comprising a seat element 1 (having a base and a seat pan) and a support leg 2, is shown. A possible display device is indicated schematically by the reference numeral 3. Additionally or alternatively, the display device may also be located at reference numeral 4.

(15) It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
