Child seat fixing device
View Patent ↗A device is provided for fixing a child seat to a support structure of a motor vehicle, including a plastically deformable holding device, which is fixed to the support structure and has a holding element to which a fixing element, which is attached to the child seat, can be fixed. In order to permit a defined movement of the holding element during deformation of the holding device, the holding device has at least one bending axis along which the holding device can be deformed when a force, such as a tensile force, acts on the holding element.

at least one bending axis along which the holding device is deformable when a tensile force acts on the holding element; wherein
the holding device is configured to be attachable to the support structure,
the holding device has a plurality of bending axes arranged transversely with respect to the vehicle longitudinal direction, and
the holding device is configured to be successively deformed in a defined bending sequence along a particular bending axis when the tensile force acts on the holding element.
2. The device as claimed in claim 1 , wherein the bending axis is arranged transversely with respect to the vehicle longitudinal direction.
3. The device as claimed in claim 2 , wherein:
the holding device includes a plurality of bending axes arranged transversely with respect to the vehicle longitudinal direction, and
the holding device is configured to be successively deformed in a defined bending sequence along a particular bending axis when the tensile force acts on the holding element.
4. The device as claimed in claim 3 , wherein the holding device comprises:
a first bending axis which, both in an undeformed state and in a deformed state of the holding device, is arranged below an upper edge of the support structure; and
a second bending axis which, in the undeformed state of the holding device, is arranged below the upper edge of the support structure and below the first bending axis, and, in the deformed state, is arranged above the upper edge of the support structure.
5. The device as claimed in claim 4 , wherein the holding device further comprises:
a fixing portion delimited by the first bending axis; and
a lever portion arranged between the first and second bending axes;
wherein the holding element is delimited by the second bending axis.
6. The device as claimed in claim 2 , wherein:
the holding device includes a first bending axis delimiting a fixing portion, a second bending axis, and a third bending axis delimiting a holding portion, and
a respective lever portion is formed between the first and second bending axes and between the second and third bending axes.
7. The device as claimed in claim 2 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
8. The device as claimed in claim 1 , wherein the holding device comprises:
a first bending axis which, both in an undeformed state and in a deformed state of the holding device, is arranged below an upper edge of the support structure; and
a second bending axis which, in the undeformed state of the holding device, is arranged below the upper edge of the support structure and below the first bending axis, and, in the deformed state, is arranged above the upper edge of the support structure.
9. The device as claimed in claim 8 , wherein the holding device further comprises:
a fixing portion delimited by the first bending axis; and
a lever portion arranged between the first and second bending axes;
wherein the holding element is delimited by the second bending axis.
10. The device as claimed in claim 9 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
11. The device as claimed in claim 8 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
12. The device as claimed in claim 1 , wherein:
the holding device includes a first bending axis delimiting a fixing portion, a second bending axis, and a third bending axis delimiting a holding portion, and
a respective lever portion is formed between the first and second bending axes and between the second and third bending axes.
13. The device as claimed in claim 1 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
14. The device as claimed in claim 12 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
15. The device as claimed in claim 3 , wherein the holding device is formed from a piece of plastically deformable sheet metal.
16. A plastically deformable holding device for fixing a child seat to a support structure of a motor vehicle, comprising:
a first means for attaching the holding device to the support structure;
a second means for attaching the holding device to a fixing element attached to the child seat; and
a lever portion, disposed between the first and second means, including at least one bending axis along which the holding device is deformable when a tensile force acts on the second means, wherein
the holding device has a plurality of bending axes arranged transversely with respect to the vehicle longitudinal direction, and
the holding device is configured to be successively deformed in a defined bending sequence along a particular bending axis when the tensile force acts on the second means.
17. A plastically deformable holding device for fixing a child seat to a support structure of a motor vehicle, comprising:
a fixing portion attachable to the support structure;
a holding portion attachable to a fixing element of the child seat; and
a lever portion, disposed between the fixing portion and the holding portion, including at least one bending axis along which the holding device is deformable when a tensile force acts on the holding portion, wherein
the holding device has a plurality of bending axes arranged transversely with respect to the vehicle longitudinal direction, and
the holding device is configured to be successively deformed in a defined bending sequence along a particular bending axis when the tensile force acts on the holding portion.
