Abstract

The present invention is directed to a device for at least partially covering a vehicle floor pan of a motor vehicle, comprises a carrier element made at least by a hard foam material, a vibration decoupling element made at least by a soft foam material, a surface layer to visually cover the device from the top, wherein the device has a shield element, which is made at least by a plastic material and is configured for accepting, absorbing and distributing the energy of a localized impact stress, which is applied on the device from above against the shield element. The present invention is also directed to a method for producing the device.

First claim

The invention claimed is:

1. A device adapted for at least partially covering a vehicle floor pan of a motor vehicle, comprising:
a carrier element made of at least a hard foam material;
a vibration decoupling element made of at least a soft foam material;
a surface layer to visually cover the device from the top;
a shield element made of at least a plastic material and configured for accepting, absorbing, and distributing the energy of a localized impact stress applied on the device from above and against the shield element; and
wherein the shield element has at least one passage section configured for allowing the soft foam material to pass through at least a part of the shield element during production of the device.

2. The device according to claim 1 , wherein at least the carrier element and the shield element are connected by the soft foam material of the vibration decoupling element.

3. The device according to claim 1 , wherein the shield element is placed above an upper side of the carrier element and supported by the same.

4. The device according to claim 1 , wherein the shield element has a border section supported by at least one support region of the carrier element.

5. The device according to claim 1 , wherein the carrier element has at least one passage section that is vertically aligned with the at least one passage section of the shield element.

6. The device according to claim 1 , wherein the carrier element has at least one empty compartment configured to receive the soft foam material during production of the device.

7. The device according to claim 6 , wherein the shield element is at least in part covering the at least one empty compartment.

8. The device according to claim 6 , wherein the at least one passage section of the shield element includes a second passage, and wherein the at least on passage section of the shield element and the at least one empty compartment are configured to allow the soft foam material pass the second passage section to at least partially enter the empty compartment during production of the device, and wherein the empty compartment serves as a degassing space for the soft foam material.

9. The device according to claim 1 , wherein the at least one passage section of the carrier element, the at least one passage section of the shield element, and the at least one empty compartment are configured to allow the soft foam material to subsequently pass at least one passage section of the carrier element, at least one passage section of the shield element, then a channel section of the shield element, then at least one second passage section of the shield element, and to at least partially enter the empty compartment during production of the device, and wherein the empty compartment serves as a degassing space for the soft foam material.

10. The device according to claim 1 , wherein the shield element comprises at least two passage sections, which extend substantially vertical through the shield element, and at least one channel section, which extends substantially non-vertically along the shield element, and which connects the at least two passage sections.

11. The device according to claim 1 , wherein the shield element is configured to serve as a support and impact zone for the support bar of a child seat in a motor vehicle.

12. A method of using the device according to claim 1 for supporting the stand of a child seat in a motor vehicle.

13. A method for producing a device for at least partially covering a vehicle floor pan of a motor vehicle, comprising:
providing a carrier element made at least by a hard foam material;
providing a vibration decoupling element made at least by a soft foam material;
providing a surface layer to visually cover the device from the top;
providing a shield element, which is made at least by a plastic material and is configured for accepting, absorbing, and distributing the energy of a localized impact stress applied on the device from above against the shield element, wherein the shield element has at least one passage section configured for allowing the soft foam material to pass through at least a part of the shield element during production of the device; and
assembling said components for providing the device.

14. The method according to claim 13 , including the step of applying a reaction injection molding process to provide the vibration decoupling element, and to connect at least two or all of the components of the device.
