Abstract: An anchoring arrangement of an end point or deflection point of a safety belt, especially in motor vehicles, under interposition of a spring at a fixed vehicle part; the spring is installed prestressed in the sense of a tightening of the belt band and is blocked in the normal driving operation in this position while the blocking is released by a force peak exceeding the prestress force of the spring which occurs at the beginning of an accident at the belt band.

Abstract: A pneumatic spring for vehicles which spring includes two supports as well as at least one closed spring volume and two differently sized spring areas which are subjected to a pressure acting in opposite directions. The two spring surfaces are separated from one another and are variable in size as a function of the travel of the pneumatic spring, two roll bellows are arranged in a casing of the pneumatic spring with opposite spring surfaces of the bellows being supported upon connected spring pistons. The supports are formed, on the one hand, by the spring pistons and, on the other hand, by a casing associated with the walls of the roll bellows. Partial volumes are defined by the roll bellows with the partial volumes being separated from one another so as to maintain the respective volumes essentially independent of the travel of the pneumatic spring.

Abstract: A thermostatic control valve for maintaining an essentially constant set value of an operating temperature of a liquid coolant which is conductible through a cooling jacket of an internal combustion engine. The thermostatic control valve includes a warm-up valve for suppressing a coolant flow at least in a partial area of the cooling jacket, a radiator valve for supplying coolant emerging from a coolant outlet of the cooling jacket to a radiator, and a bypass valve for returning the liquid coolant emerging from the cooling jacket bypassing the radiator to a coolant inlet of the cooling jacket. A single thermostatic regulating element, responsive to temperature changes and adapted to execute regulating movements is provided for actuating the radiator valve, bypass valve, and additionally actuating the warm-up valve.

Abstract: A bearer, especially a longitudinal bearer of a motor vehicle frame, which is constructed as hollow profile and includes a deformable section dissipating impact energy; the walls of the longitudinal bearer have different strength characteristics as a result of a treatment of these areas changing the strength of the wall material compared to non-treated areas; a greater strength thereby exists in the treated wall areas than in the untreated areas.

Abstract: A truck with a driver cab that includes two separate structural units, of which one is equipped as independently spring-supported operating cell essentially only with seating elements or seating and berthing elements as well as with control and operating elements while the other unit forms as covering and/or support unit a mounting unit for the operating cell and shields the operating cell on the rear side or on the rear and bottom side thereof.

Abstract: A door guide for a rear door or tailgate of a station wagon with the guide including a first member, fixed to a body portion of the station wagon, having at least one wedge-shaped recess which is adapted to receive a projection of a second fitting member, fixed to the door or tailgate, when the door or tailgate is closed. The second member includes a metallic base body with the projections thereof having, in run-in zones, two opposed recesses. An elastic abrasion-resistant material is applied by an extrusion coating on the base body with a projecting bead-like elevation of material being provided at the projections. The bead-like material is adapted to be at least partly forced into extrusion-coated recesses in the process of closing the door or tailgate.

Abstract: A servo brake system with at least two circuits, equipped with a tandem master cylinder, in which two working pistons are arranged coaxially one behind the other; a transmission shifting device thereby automatically shifts in case of failure of the servo installation to a larger pedal travel with a mechanically applied brake pressure that is reduced within permissive limits; the working piston of the actuating side thereby includes a bore coaxial to the other working piston, in which a plunger piston is guided which is actuatable by the input piston.
