Child safety seat for attaching to a motor vehicle seat

Abstract

A child seat for mounting on a motor vehicle seat is comprised of at least one contact surface device for a child accommodated in the child seat, the contact surface device having at least a first section and a second section, the second section being transferable relative to the first section from a first position to a second position by the action of an at least partially outwardly directed force acting on the second section to damp deceleration of the child in the case of a displacement of the child towards the second section.

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

(21) FIG. 1 shows an oblique view of a child seat according to the invention, in which the contact surface device according to the invention cannot be seen in detail. An area suitable for the formation of the second section (effective area) is marked by a dashed line 9.

(22) FIGS. 2 and 3 show schematically a detail of a wall (shell) of an inventive child seat according to a first embodiment. This embodiment has an inner wall 10 and an outer wall 11. The inner wall 10 in turn has a second section 13 (effective area) and a first section 12. The second section 13 can be moved or pivoted in relation to the first section 12 (see FIG. 3) when an outwardly directing force is applied (in the direction of the outer wall 1). The first section 12 and second section 13 are structurally separated from each other by a delimiting section 14 (not defining a fixed connection) and a transition section 15 (preferably defining a fixed, in this case articulated, connection). In FIG. 2 the second section 13 is in the first position (without force load), in FIG. 3 the second section is in the second position in the state of (maximum) deflection.

(23) The embodiment according to FIGS. 4 and 5 essentially corresponds to the embodiment according to FIGS. 2 and 3, wherein a blocking device (stop) 16 is provided in addition. The blocking device prevents the second section 13 from swiveling inwards if, for example, an object from outside deforms or breaks through the outer wall. If necessary, the blocking device may also enable the second section 13 to have a pre-tension inwards (in the position according to FIG. 4).

(24) The embodiment according to FIGS. 6 and 7 corresponds to the embodiment according to FIGS. 4 and 5 with the difference that the wall here is only doubled in sections, i.e. the outer wall 11 does not extend over the entire inner wall 10. However, according to the embodiment the second section 13 is arranged in the area that is double-walled.

(25) In contrast to FIGS. 2 to 7, FIGS. 8 and 9 show a single-walled wall with only one wall 17, but with a blocking device 16 as in FIGS. 4 and 5.

(26) FIGS. 10 and 11 again show a double-walled embodiment, basically in accordance with FIGS. 4 and 5. However, in contrast to FIGS. 4 and 5, the second section 13 is not pivotable in relation to the first section 12, but is movable translationary and mounted via a spring element 18. The spring element 18 is located between an outer surface 19 of the second section 13 and an inner surface 20 of the outer wall 11. There is a delimiting section 14, but no transition section (cf. transition section 15 according to FIG. 2).

(27) FIG. 12 shows a side view of the inventive child seat (with hidden hood) including the second section 13 (or the effective area). This second section 13 has a trapezoidal geometry and tapers towards the rear. The second section 13 is shown again enlarged in FIG. 13.

(28) FIG. 14 shows a section through the child seat according to FIGS. 12 and 13, viewing to an inner side of the second section 13. A corresponding enlargement of the detail around the second section 13 is shown in FIG. 15.

(29) FIG. 16 shows an oblique view of the inventive child seat according to FIG. 12, now with a hood, with a view to the inside of the second section 13.

(30) FIG. 17 shows an oblique view of the seat with the second section 13 superimposed (at least to a large extent) by the top 21.

(31) FIG. 18 shows a section through the child seat (with hood 21) so that the position of the second section 13 in relation to hood 21 can be seen. Specifically, FIG. 18 shows that the second section 13 (upwards, to the front and rear) is bordered by a delimiting section 14 and (downwards) by a transition section 15 as a transition to the first section 12. The edge surfaces extending upwards or downwards (essentially vertically) are movable or pivotable, respectively, in relation to the remaining wall of the child seat (in particular the first section 12), just like the (upper) delimiting section 14.

(32) In FIGS. 12-18 (see, for example, FIG. 12), a side impact protection element 22 is also shown, which can be moved (swiveled) outwards (from an outer wall of the wall of the child seat) to improve side impact protection against an external impact. In contrast to the second section 13 (the effective area), the side impact protection element 22 is arranged and configured in such a way that it is movable (at least not to a considerable extent) by the fact that the child can be moved in the direction of the contact surface (inner wall side) upon its displacement or impact. Rather, preferably a separate actuating means is provided or a separate actuation is required for its movement, which allows the child seat (for example after its mounting on the vehicle seat) to be adjusted in such a way that the side impact protection 22 is displaced outwards, for example swiveled outwards.

(33) A fundamental conceptual difference between the side impact protection and the configuration of the second section 13 (or the damping area element) is therefore that the side impact protection 22 is already (sensibly) displaced or pivoted outwards before an impact situation (accident situation) and the third section 13 is only displaced accordingly by the impact of the child against an inner wall side of the child seat in order to damp this impact.

(34) Second section 13 and/or side impact protection element 22 may be provided in multiple, in particular double, construction (for example, a second section 13 or a side impact protection element 22, respectively, on one side at a time).

(35) It should be noted at this point that all parts described above, taken individually and in any combination, in particular the details shown in the drawings, are claimed to be essentially inventive. Modifications of this are familiar to the skilled person.
