Abstract
An inductive power transfer pad for a system for inductive power transfer to a vehicle includes 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. The stationary part has 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, wherein the at least one supporting surface on the upper edge is an inclined surface. The movable part includes at least one first contacting surface which contacts the at least one first supporting surface when the movable part is in the resting position, with the first contacting surface fitting to the first supporting surface.
