Description

[0001] Child seat with foam element

[0002] Description

[0003] The invention relates to a child seat for mounting on a motor vehicle seat.

[0004] Child seats, for example, can have injection-molded elements, such as a seat body. For comfort and / or safety reasons, foam elements are often attached to these injection-molded elements for cushioning (e.g., to absorb impact energy). Such foam elements must be attached so that they are in a defined location to exert their full effect. Form-fitting connections and gluing are possible methods for this. Gluing can be achieved, for example, using liquid adhesive and / or adhesive tape. When foam elements touch other elements, particularly injection-molded elements or other foam elements, annoying squeaking noises can occur. This can occur particularly with particle foams, and especially with EPS (expanded polystyrene).For this reason, the state of the art usually involves full-surface bonding, as for example in CN 204 605 583 U.

[0005] The object of the invention is to provide a cost-effective and safe child seat with a foam element, which is also particularly comfortable to use.

[0006] This problem is solved in particular by the features of claim 1.

[0007] In particular, the object is achieved by a child seat for attachment to a motor vehicle seat, comprising at least one seat body and at least one foam element, preferably a particle foam element, which is attached to the seat body by means of an adhesive, wherein the foam element covers a seat body overlay section with a foam element overlay section, wherein the foam element preferably has an outer side which is opposite the foam element overlay section, wherein the foam element overlay section has at least one foam element adhesive surface and at least one foam element support surface, and the seat body overlay section has at least one seat body adhesive surface and at least one seat body support surface, wherein the foam element adhesive surface and the seat body adhesive surface are fastened to one another by the adhesive,while the foam element support surface and the seat body support surface (in the absence of external forces) are spaced apart.

[0008] One idea of ​​the invention is to divide the foam element and the seat body in their respective overlapping section in such a way that at least one adhesive surface is present in each case and at least one support surface is present in each case, which is spaced from a complementary support surface. The foam element support surface and the seat body support surface are thus coordinated with one another and with the foam element adhesive surface and the seat body adhesive surface in such a way that they are spaced from one another in the absence of external forces. This makes it possible to achieve secure fastening which is also pleasant to use. In particular, squeaking noises are reduced or prevented, since these do not (cannot) arise in the area of ​​the adhesive joints or in the area where there is a space. Nevertheless, secure fastening can be achieved with comparatively little adhesive.

[0009] The seat body preferably forms a basic structure (supporting structure / supporting skeleton) of a seat section and / or a back section of the child seat, in particular a side wing of the seat section and / or the back section, wherein the back section can include a (possibly height-adjustable) headrest with its own side wings. The seat body can further include an impact shield.

[0010] The seat body can be made (at least 50 wt.%, preferably at least 80 wt.% or at least 95 wt.%) of plastic, preferably polymer and / or a thermoplastic, in particular by injection molding. The plastic is preferably at least substantially non-porous and / or has a density of at least 0.1 g / cm 3 or at least 0.5 g / cm 3 or 0.8 g / cm 3 and / or a maximum of 5.0 g / cm 3 or a maximum of 2.0 g / cm 3 aufThe plastic may comprise (at least 50% by weight, at least 80% by weight, or at least 95% by weight) polyethylene and / or polypropylene.

[0011] The seat body may have a seat body overlay portion covered by the foam element (so that the foam element overlays the seat body in its overlay portion). The foam element overlay portion is particularly designed to cover or overlap the seat body overlay portion, with the foam element overlay portion and the seat body overlay portion abutting one another at least in sections.

[0012] The outer side of the foam element is located, in particular, at least partially opposite the foam element overlay section. According to the embodiment, the entire outer surface of the foam element that is not designed as a foam element overlay section can form the outer side. The outer side can be substantially continuous and / or configured such that the foam element is at least substantially non-concave in the region of the outer side. It is possible for the outer side to be perforated and / or have a surface structure.

[0013] The seat body overlay section is preferably a section of the seat body intended to support (a part of) the body of a child seated in the child seat. In particular, this can be the inside or outside of a section that supports the child in the event of a side impact. Particularly preferably, the seat body overlay section is a section of a (possibly height-adjustable) headrest, in particular an inside or outside thereof, preferably an inside thereof. In a specific, particularly preferred embodiment, the respective seat body overlay section is arranged on an inside of a (respective) side wing of the headrest (and / or on the outside of this wing).

Preferred areas for foam elements according to the invention or corresponding sections of the seat body are: an inner side 18 of a side bolster 19 of a headrest 20, an outer side 21 of the side bolster 19 of the headrest 20, and an inner side 22 of a side bolster 23 of a seat shell (in particular an upper section thereof, which is located in the region of an adjustable height of the headrest). A central section of the headrest (intended to support the back of a child's head) and / or the side of an impact shield facing a child (not shown) can also be suitable areas.

[0068] Fig. 4 shows another view of the foam element 10 shown in Fig. 1.

[0069] Fig. 5 shows a sectional view of the foam element 10 together with a portion of the associated seat body (more precisely: the associated headrest). The foam element adhesive surface 12 rests against the seat element adhesive surface 25 (adhesive not shown), while the foam element support surface 13 is spaced apart from the seat body support surface 24.

[0070] Fig. 6 shows a headrest 20 without the corresponding foam elements 10. Therefore, ribs 27 can be seen in the seat body overlay section 26, which are provided for engaging in the channels 15 of the foam element 10.

[0073] Furthermore, it is pointed out that the broadest possible scope of protection is sought. In this respect, the disclosure contained in the claims can also be clarified by features that are described with further features (even without these further features being mandatory). It is explicitly pointed out that parentheses and the term "in particular" are intended to emphasize the optionality of features in the respective context (which does not mean, conversely, that without such identification, a feature is to be considered mandatory in the corresponding context). The term "element / elements" should preferably characterize a coherent structure, which in turn can be connected to at least one other structure (to form a possibly integral and / or inherently immobile overall structure) or can be delimited from all other structures.
