The invention relates to a folding ramp for vehicles comprising a ramp plate and a ramp tray, which ramp tray has at least one inductive sensor integrated into the ramp tray. The sensor has a covering cap, which extends beyond an opening in the ramp tray for accommodating the sensor, by means of a supporting edge. The covering cap is mechanically decoupled from a sensor element in the interior of the housing. The covering cap is preferably composed of a glass-fiber-reinforced plastic and thus can absorb high compressive forces without the sensor element being loaded.
