Inductive power transfer pad

1. An inductive power transfer pad for a system for inductive power transfer to a vehicle, the inductive power transfer pad comprising:

a stationary part; and

a movable part which, in a resting position, rests on the stationary part and which is upwardly movable in a Z-direction relative to the stationary part in order to reach a higher position,

wherein:

the stationary part comprises a frame surrounding the stationary part on at least three sides, the frame having at an upper edge which is oriented towards the movable part,

the upper edge has at least one first supporting surface on which the movable part rests when it is in the resting position,

the at least one first supporting surface on the upper edge is an inclined surface,

the movable part comprises at least one first contacting surface which directly and/or indirectly rests on the at least one first supporting surface when the movable part is in the resting position,

the first contacting surface fits to the first supporting surface, and

wherein the first contacting surface directly contacts the first supporting surface in the resting position or wherein one or more further elements are located between the first contacting surface and the first supporting surface in the resting position.

2. The inductive power transfer pad according to claim 1 , wherein two or more first contacting surfaces are present which are inclined in different directions.

3. The inductive power transfer pad according to claim 1 , wherein the movable part comprises a base, wherein the base comprises the first contacting surface.

4. The inductive power transfer pad according to claim 1 , wherein the stationary part comprises one or more protrusions in the Z-direction, each of the one or more protrusions comprising a second supporting surface, and

wherein the movable part comprises at its bottom side a second contacting surface which rests on the second supporting surface when the movable part is in the resting position.

5. The inductive power transfer pad according to claim 1 , wherein the movable part comprises an outer edge on an upper side which is a rounded edge or which comprises an inclining part.

6. The inductive power transfer pad according to claim 1 , wherein the movable part comprises at its bottom side a protrusion having a first lateral surface, wherein, in the resting position, the first lateral surface rests on a second lateral surface which is formed at the stationary part.

7. The inductive power transfer pad according to claim 1 , wherein one of the movable part and the stationary part comprises a protrusion which is placed in a recess of the stationary part or of the movable part when the movable part is in the resting position.

8. The inductive power transfer pad according to claim 1 , further comprising an electronic housing, and a receiving section for the movable part, wherein the electronic housing comprises, on its outside, a third supporting surface which is an inclined surface, wherein a third contacting surface, which is formed at the movable part, rests on the third supporting surface when the movable part is in the resting position, and wherein the third contacting surface fits to the third supporting surface.
