CONNECTING ELEMENT FOR SNAP CONNECTIONS
Pairs of corresponding connecting elements for connecting two components at a predefined joining direction by a catch connection fixedly attached to the components to be joined, such that one of the connecting elements has a structure suitable for engaging behind the catch face and the catch face behind which the structure is to engage is situated on the other element of the corresponding connecting elements. At least one of the two connecting elements has a ramp-shaped structure with which the respective other connecting element is in contact during the joining movement and which ensures an elastic deformation as the deflection in preparation for the locking engagement of at least one of the connecting elements during the joining movement, such that the catch face behind which the structure is to engage is situated behind the ramp-shaped structure in the joining direction.
1 . A catch connection for connecting a first component to a second component in a predefined joining direction comprising:

a second connecting element fixedly attached to the second component, the second connecting element including a ramp-shaped structure and a catch face, the ramp-shaped structure deforming the first connecting element during a joining movement in a joining direction between the first component and the second component, wherein the engaging structure of the first connecting element engages the catch face of the second connecting element to connect the first component to the second component; and wherein the catch face is inclined in respect of the joining direction.
2 . The catch connection according to claim 1 , wherein the first connecting element is elastically deflectable.
3 . The catch connection according to claim 1 , wherein the catch face is inclined at an angle which does not exceed an angle of friction between the catch face and the engaging structure.
4 . The catch connection according to claim 1 , wherein the catch face has a convex surface.
5 . The catch connection according to claim 1 , wherein a burr is formed on the catch face parallel to the joining direction.
6 . The catch connection according to claim 1 , wherein the first connecting element is a snap strap and the second connecting element is a catch nose, wherein the snap strap is adapted to receive the catch nose therein.
7 . The catch connection according to claim 1 , further comprising positioning aids arranged on the first component and the second component.
8 . The catch connection according to claim 1 , wherein the first connecting element is a hook.
9 . A catch connection for connecting a first component to a second component in a predefined joining direction comprising:
a first connecting element fixedly attached to the first component, the first connecting element including an engaging structure formed thereon, wherein the first connecting element is elastically deflectable in a deflection direction; and
a second connecting element fixedly attached to the second component, the second connecting element including a ramp-shaped structure and a catch face, the ramp-shaped structure deflecting the first connecting element in the deflection direction during a joining movement in a joining direction between the first component and the second component, wherein the engaging structure of the first connecting element lockingly engages the catch face of the second connecting element to connect the first component to the second component; and wherein the catch face is inclined in respect of the ramp-shaped structure and the joining direction.
10 . The catch connection according to claim 9 , wherein the catch face is inclined at an angle which does not exceed an angle of friction between the catch face and the engaging structure.
11 . The catch connection according to claim 9 , wherein the catch face has a convex surface.
12 . The catch connection according to claim 9 , wherein a burr is formed on the catch face parallel to the joining direction.
13 . The catch connection according to claim 9 , wherein the first connecting element is a snap strap and the second connecting element is a catch nose, wherein the snap strap is adapted to receive the catch nose therein.
14 . The catch connection according to claim 9 , further comprising positioning aids arranged on the first component and the second component.
15 . The catch connection according to claim 9 , wherein the first connecting element is a hook.
16 . A catch connection for connecting a first component to a second component in a predefined joining direction comprising:
a first connecting element fixedly attached to the first component, the first connecting element including an engaging structure formed thereon, wherein the first connecting element is elastically deflectable in a deflection direction; and
a second connecting element fixedly attached to the second component, the second connecting element including a ramp-shaped structure and a catch face, the ramp-shaped structure deflecting the first connecting element in the deflection direction during a joining movement in a joining direction between the first component and the second component, wherein the engaging structure of the first connecting element lockingly engages the catch face of the second connecting element to connect the first component to the second component; and wherein the ramp-shaped structure is disposed at an angle α in respect of the joining direction and the catch face is disposed at an angle β in respect of the joining direction.
