According to one embodiment of the invention, a method is devised for tailoring downloaded content to the requesting device by receiving attribute parameters associated with a device that initiates a request for downloaded content. The screwing operation of the screw rod with respect to the adjusting unit will adjust an elevation of the handle. The fluid pump also provides fluid outflow when the rotational direction of the input drive is reversed. The air guiding slats are positioned so that part of the radiator outlet air is guided to the vehicle outside and a further part of the radiator outlet air can be supplied to the vehicle inside and via a deflecting blade to a wheel brake for cooling. The outer guard portion is pivotally connected with the inner guard portion about a pivotal axis which is substantially parallel to each side of the blade. The resilient piece is deformed when the housings are connected and the slider is propelled by the springs to the deformation preventing position.
