Abstract

A fold-out component body (1), in particular an armrest of a vehicle seat, can be rotated about an axis of rotation (4) from a stowage position (9) into a usage position (10). In the event of an accident, the fold-out component (1) can be secured in the stowage position thereof by a locking element (2).

First claim

The invention claimed is:

1. A vehicle seat fold-out component, the fold out component comprising:
a component or an armrest rotatable about an axis of rotation from a stowage position into a use position;
a locking element, the component or the armrest being securable in the stowage position by the locking element in the event of an accident, wherein, in the event of an accident, the locking element rotates about an axis of rotation from an actuating position into a locking position, the locking element being provided in the form of a locking element cam disk
a component or armrest cam disk provided on the component or the armrest.

2. The fold-out component as claimed in claim 1 , wherein the axis of rotation of the component or the armrest coincides with an axis of rotation of the component or armrest cam disk.

3. The fold-out component as claimed in claim 2 , wherein the component or armrest cam disk and/or the component or the armrest has a locking contour comprising a recess, on a circumference of the component or armrest cam disk and/or the component or the armrest.

4. The fold-out component as claimed in claim 2 , wherein the component or armrest cam disk and/or the component or the armrest has a stop comprising a stop notch.

5. The fold-out component as claimed in claim 1 , wherein the second cam disk and/or the component or the armrest has a locking contour comprising a recess, on a circumference of the component or armrest cam disk and/or the component or the armrest.

6. The fold-out component as claimed in claim 1 , wherein the component or armrest cam disk and/or the component or the armrest has a stop comprising a stop notch.

7. The fold-out component as claimed in claim 1 , wherein the locking element has a circular cross section.

8. The fold-out component as claimed in claim 7 , wherein the locking element cam disk has a recess on a locking element circumference.

9. The fold-out component as claimed in claim 1 , wherein the locking element has a recess on a locking element circumference.

10. A vehicle seat fold-out component, the fold out component comprising:
a component or an armrest rotatable about an axis of rotation from a stowage position into a use position;
a first cam disk, the component or the armrest being securable in the stowage position by the first cam disk in the event of an accident; and
a second cam disk provided on the component or the armrest, wherein, in the event of an accident, the first cam disk rotates about an axis of rotation from an actuating position into a locking position, wherein the first cam is rotatable independent of movement of the second cam disk.

11. The fold-out component as claimed in claim 1 , wherein the first cam disk has a circular cross section.

12. The fold-out component as claimed in claim 11 , wherein the first cam disk has a recess on a locking element circumference.

13. The fold-out component as claimed in claim 10 , wherein the first cam disk element has a recess on a locking element circumference.

14. The fold-out component as claimed in claim 10 , wherein the first cam disk element has a recess on a locking element circumference, at least a portion of the second cam disk being arranged in the recess when the first cam disk is in the use position.

15. The fold-out component as claimed in claim 10 , wherein the first cam disk comprises a first cam disk circumferential portion extending in a circumferential direction with respect to the axis of rotation of the first cam disk, the first cam disk circumferential portion being in contact with the second cam disk when the first cam disk is in at least the locking position.

16. A vehicle seat fold-out component, the fold out component comprising:
a component or an armrest rotatable about an axis of rotation from a stowage position into a use position;
a first cam disk, the component or the armrest being securable in the stowage position by the first cam disk in the event of an accident; and
a second cam disk provided on the component or the armrest, wherein, in the event of an accident, the first cam disk rotates about an axis of rotation from an actuating position into a locking position.

17. The fold-out component as claimed in claim 16 , wherein the first cam disk element has a recess on a locking element circumference.

18. The fold-out component as claimed in claim 16 , wherein the first cam disk element has a recess on a locking element circumference, at least a portion of the second cam disk being arranged in the recess when the first cam disk is in the actuating position.

19. The fold-out component as claimed in claim 16 , wherein the first cam disk comprises a first cam disk circumferential portion extending in a circumferential direction with respect to the axis of rotation of the first cam disk, the first cam disk circumferential portion being in contact with the second cam disk when the first cam disk is in the locking position.

20. The fold-out component as claimed in claim 16 , wherein the first cam disk has a circular cross section, the first cam disk having a recess on a locking element circumference.
