Abstract: A plastic housing with a sleeve-shaped metal insert has a mounting side for attachment to a mounting side of a metal carrier body by a connector element. The plastic housing has a mounting flange defining an opening and a top edge of the flange. The sleeve-shaped metal insert is arranged in the opening of the mounting flange, and has a top edge extending over the top edge of the mounting flange and an opening therethrough. The plastic housing has projecting plastic material on the mounting side of the mounting flange which provides a spacing between the sleeve-shaped metal insert and the metal carrier body by enclosing in the shape of a ring the lower edge of the opening in the mounting flange. The projecting plastic material insulates the sleeve-shaped metal insert from the metal carrier body and provides a seal against the effects of moisture.

Abstract: The invention relates to a device for sealing pressure compensation openings in components in particular of a motor vehicle control unit. Previously, pressure compensation openings were sealed in the interior of the housing by a watertight and gas-permeable material affixed by adhesion. In accordance with the invention, the opening is sealed from the outside with a two-layered material where a wide-area first layer consists of a material that can be inscribed and a second layer, which can also be provided over just a part of the total area, is a watertight and gas-permeable membrane. At those places where pressure compensation occurs, the first layer is removed so that only the membrane acts. The first layer can be used here as a label. Advantages offered by this device are that the housing and the membrane are joined over a much larger area, the process can be monitored, and one process step is saved.

Abstract: A process and a mechanism for the direction-selective triggering of a passive safety device in a vehicle, with at least two acceleration transducers, where the acceleration transducers have directional sensitive axes and these have actual instantaneous orientations and are aligned in different, preferably specified reference orientations and there is an angle tolerance between the reference and the instantaneous orientations of the sensitive axes. An evaluation device is provided to correct the angle tolerance, comprising an electronic circuit which converts the signals (am 1, am 2, . . . am n) coming from the acceleration transducers to corrected output signals (a(I), a(II), . . . a(n)), which are linear combinations of the incoming signals with adjustable factors c.sub.ij : ##EQU1## This can lessen the expense of production compared to familiar mechanisms, without simultaneously reducing the measuring accuracy of the mechanism.

Abstract: For electrically and mechanically connecting a printed circuit board bonding pad to a metallic housing part, in particular for connecting to ground, friction-type connections such as screw fastenings or rivets are usually provided for connecting the printed circuit board directly to the housing part. However, since the printed circuit boards are mostly made of plastic material and the forces at the friction-type connections diminish, the electrical connection may become loose, especially in the aging process. To prevent this a connecting element comprising a base surface having a hole for inserting the friction-type connection to the housing part and at least one contact finger on the base surface are provided, whereby the contact finger provides connection to the printed circuit board bonding pad. The base surface is insensitive to mechanical loads at the friction-type connection and can distribute these evenly. Electrical connection is guaranteed and fabrication simplified.
