An arrangement for receiving a suitcase on a vehicle hood, particularly a rear opening hood of a motor vehicle, comprises at least three fastening elements arranged on a hood surface which are connected by way of fastening devices with support parts of the rear opening hood. Two of the fastening elements are arranged in a transverse plane and&mdash;relative to the driving direction&mdash;close to a forward hood edge, and another fastening element is arranged close to a rearward hood edge in a longitudinal center plane of the vehicle.

Tire pressure sensor for motor vehicles

A pressure switch for monitoring a tire pressure of a motor vehicle tire is fastened to a wheel rim and is actuated by the inflating pressure in the tire. The pressure switch comprises a reference pressure chamber which is sealed off by an electrically conductive switching diaphragm in the direction of the tire, and carries a contact pin interacting with this diaphragm. The switching diaphragm has a mass which is controlled as a function of centrifugal force in response to tire rotation such that the switching point of the pressure switch can be changed automatically as a function of vehicle speed.
