Abstract

A card-shaped data carrier includes an electronic chip module having at least one chip and a contact structure; and a card body having an arrangement region for receiving the chip module. The chip module is arranged in the arrangement region of the card body. The card-shaped data carrier has at least a first wood layer and at least a second wood layer. The card-shaped data carrier can be bent out of a rest position into a bent position by the application of an external force; at least one restoring element for increasing the restoring force of the card-shaped data carrier is arranged between the first wood layer and the second wood layer. The restoring element is designed such that the card-shaped data carrier can be automatically returned from the bent position to the rest position when the external force is no longer applied.

First claim

The invention claimed is:

1 . A card-shaped data carrier comprising an electronic chip module with at least one chip and a contact structure, and a card body with an arrangement region for receiving the chip module,
wherein the chip module is arranged in the arrangement region of the card body, wherein the card-shaped data carrier has at least one first wood layer and at least one second wood layer, wherein the card-shaped data carrier can be bent from a neutral position by an external action of force into a bent position, wherein at least one restoring element for increasing the restoring force of the card-shaped data carrier is arranged between the first wood layer and the second wood layer, wherein the restoring element is configured in such a way that the card-shaped data carrier can be restored automatically from the bent position into the neutral position when the external action of force is relaxed, wherein a core layer is arranged between the first wood layer and the second wood layer, wherein the at least one restoring element comprises one restoring element arranged at a surface of the core layer and a further restoring element arranged at an opposite lower face of the core layer.

2 . The card-shaped data carrier according to claim 1 , wherein the restoring element has a modulus of elasticity in the range of at least 100 kN/mm2.

3 . The card-shaped data carrier according to claim 1 , wherein the restoring element is formed from spring steel.

4 . The card-shaped data carrier according to claim 1 , wherein the restoring element is configured in the form of a strip, the restoring element being arranged in a longitudinal or transverse direction with respect to the lengthwise axis of the card body.

5 . The card-shaped data carrier according to claim 1 , wherein the restoring element is arranged homogeneously between the first wood layer and the second wood layer.

6 . The card-shaped data carrier according to claim 1 , wherein the core layer is formed from paper, nonwoven, fabric, wood or plastic.

7 . The card-shaped data carrier according to claim 1 , wherein the restoring element is embedded into the core layer or is arranged on a surface of the core layer.

8 . The card-shaped data carrier according to claim 1 , wherein the core layer has at least one antenna for contactless data transmission.

9 . The card-shaped data carrier according to claim 1 , wherein two restoring elements, configured in the form of strips, are provided, each of which is arranged in a longitudinal or transverse direction with respect to the lengthwise axis of the card body.

10 . The card-shaped data carrier according to claim 1 , wherein two restoring elements, configured in the form of strips, are provided, which are arranged crosswise with respect to one another.

11 . The card-shaped data carrier according to claim 1 , wherein four restoring elements, configured in the form of strips, are provided, two restoring elements being arranged in a longitudinal direction with respect to the lengthwise axis of the card body and two restoring elements being arranged in a transverse direction with respect to the lengthwise axis of the card body.

12 . The card-shaped data carrier according to claim 1 , wherein the one restoring element arranged at the surface of the core layer has a different shape than the further restoring element arranged at the opposite lower face of the core layer.
