Abstract

A child seat which can be fastened to a vehicle seat of a vehicle by means of a fastening system comprises a child belt system for securing a child sitting on the child seat apparatus for coupling a vehicle seat belt system, which has a belt strap and a belt strap tensioning device, to the belt system of the child seat. The coupling apparatus is designed such that, when the belt strap tensioning device is activated, the child seat belt system is also tensioned. The coupling apparatus has a holder into which the belt strap provided on the vehicle can be hooked. holder is designed and arranged in such a manner that it serves to receive the lap belt section of the vehicle'"'"'s belt strap.

Claims

1-12. -12. (canceled)

13. A child seat having a fastening system for fastening the child seat to a vehicle seat, said child seat comprising:

a child belt system for securing a child sitting on the child seat;

means for coupling the child belt system to a vehicle seat belt system having a belt strap and a belt strap tensioning device;

wherein,

the coupling means has a configuration such that, when the belt strap tensioning device is activated, the child belt system is also tensioned;

the coupling means has a holder into which the belt strap provided on the vehicle can be hooked; and

the holder is configured and arranged in such a manner that it serves to receive a lap belt section of the vehicle'"'"'s belt strap.

14. The child seat as claimed in claim 13, wherein the holder is configured such that, when the vehicle'"'"'s belt strap tensioning device is activated, said holder is pulled downward, relative to a vertical direction, by the lap belt section hooked into it.

15. The child seat as claimed in claim 13, wherein the holder has a hook into which the lap belt section can be hooked.

16. The child seat as claimed in claim 15, wherein the hook is configured such that, when the belt strap tensioning device is activated in the longitudinal extent of the belt strap, the lap belt section can be pulled through.

17. The child seat as claimed in claim 13, wherein at least one of a shoulder belt and a tightening strap of the child belt system is coupled to the holder.

18. The child seat as claimed in claim 13, wherein the child seat has belt force limiting means which permit the maximum belt force to be matched to the height or weight of a child sitting in the child seat.

19. The child seat as claimed in claim 18, wherein:

the belt force limiting means includes a first belt force limiting device are formed by a deformation region of the holder;

the holder can be deformed, increasing its length in response to application of a certain threshold value of a tensioning force to the holder by means of the belt strap tensioning device.

20. The child seat as claimed in claim 18, wherein the belt force limiting means includes a second belt force limiting device formed such that the at least one of a shoulder belt and the tightening strap of the child belt system is provided with at least one loop fastened with at least one tear seam.

21. The child seat as claimed in claim 17, wherein:

the belt force limiting means includes a third belt force limiting device formed by the connecting holder to the at least one child seat shoulder belt via at least one coupling strap; and

the coupling strap is fastened to the child seat shoulder belt by at least one tear seam.

22. The child seat as claimed in claim 21, wherein the coupling strap is guided via at least one deflecting element.

23. The child seat as claimed in claim 13, wherein the holder is formed as a single piece.

24. The child seat as claimed in claim 13, wherein the holder is fitted to the child seat such that it can be interchanged.

25. The child seat as claimed in claim 19, wherein the deformation region comprises a deformable corrugated portion.

26. The child seat as claimed in claim 23, wherein the single piece comprises a sheet metal part.
