Abstract: A motor vehicle has an actuator device for raising a bonnet in an accident to minimize injury to a pedestrian. The actuator device has at least two actuators for raising the bonnet. A control unit activates actuators with a time delay. Alternatively, the actuators differ in power. The time delay between activating the actuators or the differing power of the actuators reduces vibration while raising the bonnet, thereby ensuring proper raising of the bonnet and enhancing protection to the pedestrian.

Abstract: The invention relates to a novel family of oligomeric and polymeric s-triazine and s-heptazine derivatives and to their use as an intermediate, e.g. as precursors for producing Si/(M)/C/N/(O) ceramics, as mesoporous materials such as, e.g., catalyst carriers for storing gas or as a stationary phase for chromatography, as flameproofing agents, plastic additives or for other organic/inorganic functional materials.

Abstract: In accordance with the invention, a laminate of two or more layers and the method of making it is provided. The laminate includes at least one organic synthetic filament non-woven layer, and at least one woven web or scrim of glass fibers pre-consolidated by a binding agent. The polyester non-wovens and the woven webs or scrims are bound by needling such that a part of the (e.g., polyester) filaments penetrate through the laminate and emerge at the lower surface of the laminate and lie adjacent thereto The formed laminate is subjected to a final consolidation by an acrylate or a styrene binder.

Abstract: A compound having a space spinel structure and the formula Si3-x Cx N4 wherein 0<x?1. An example of the compound is spinel silicon carbonitride. The compound of the invention may be made by providing a silicon carbo-diimide compound and subjecting the compound to elevated temperature and pressure conditions.

Abstract: A cushioning for the seat part and/or the backrest of a vehicle seat has a cushioning layer, a ventilation layer which is arranged above the cushioning layer and through which air can flow a cushioning cover which spans the cushioning surface and in which quilt seams for forming cushioning contours are made which penetrate the ventilation layer, and at least one electric fan for actively ventilating the cushioning which is accommodated in an air duct penetrating the cushioning layer. For the purpose of a constructively simplified design of the cushioning for lowering the manufacturing costs, the at least one air duct with the integrated fan is arranged in an area of a quilt seam such that the air flowing out of the air duct flows on both sides of the quilt seam into the ventilation layer. A low-cost vibration damping is achieved in that the fan is embedded in a rubberized-hair layer which is positioned in the ventilation-layer-side mouth area of the air duct in the cushioning layer.

Abstract: A backrest for vehicle seats, has a backrest frame, a backrest cushion which is fastened thereto and consists of a cushion layer and of a ventilation layer which covers the cushion layer and through which air can flow. A fan is provided for the active ventilation of the backrest cushion. For the purpose of improving the sitting comfort, the vehicle seat is equipped with a lordosis support, the fan being fastened largely centrally in the cushion area on the lordosis support at low vibrations. The fan is situated inside an air duct constructed in the cushion layer, the clear cross-section of the air duct being dimensioned such that the fan remains inside the air duct during its movement going along with the lordosis adjustment.
