Abstract: The invention is related to an articulated joint fitting preferably for automotive vehicles with a wobble gearing to create a swivelling motion of the joint parts. As a development of the articulated joint fitting, a reduction of costs is achieved in that the spur gear wheel is composed of a plurality of elements and a simplified adjustment of the eccentric with respect to one of the articulated joint fittings is attained.

Abstract: A spindle drive for a vehicle seat connected with an upper rail. According to this invention, an upper rail slides on the surface of a drive nut preferably made of plastic whose internal thread is engaged by the spindle. Advantageous further developments deal with improving the longitudinal guidance of the upper rail on the drive nut as well as with preventing the upper rail from radially moving away from the drive nut.

Abstract: A retaining system for passengers of an automotive vehicle in which an impact element, which is movable toward the part of the body to be retained in case of a crash, is fixed to the vehicle in front of the passenger of the vehicle and is moved into position to block the space in front of the seat on which the passenger is seated only in a crash situation. This retaining system is intended to prevent the so-called "submerging" effect, by which a passenger slides into the space in front of the seat upon which the passenger is seated in a crash situation. The retaining system includes an impact element which is swingable toward the passenger about an axis which extends transversely to the longitudinal axis of the vehicle. If the interior design of the vehicle requires, the impact element can be arranged to undergo translatory movement in the direction of the passenger in addition to the swinging movement.

Abstract: A bumper system including an extendable bumper resiliently disposed in the direction of impact. The system is compact and, even at elevated impact speeds, protects the automotive vehicle against damage. The bumper is extended by an adequate amount before or during the situation of danger. A progressive damping characteristic and a suitable drive to quickly extend and to safely return the bumper are provided.

Abstract: A convertible motor vehicle is provided with two rollover bars which can be swivelled out of a lowered inoperative position into an upwardly directed supporting position and back around a swivel axis fixed at the vehicle and extending essentially in the longitudinal direction of the vehicle. The rollover protection system can be integrated into conventional vehicle concepts in a particularly space-saving and advantageous manner and reduces the risk of injury in the case of a fast, sensor-controlling swinging-up of the rollover bars.

Abstract: An inductive pulse generator for converting a rotary movement into a frequency proportional therewith. The pulse generator includes a measuring wheel (1) provided with poles (3) of magnetic material evenly distributed over the circumference of the measuring wheel. The pulse generator further includes a stator (4) provided with a magnetic core (6) with plate-shaped pole shoes (10) in a coil carrier (8) out of which end portions (12) of the pole shoes (10) project. The end portions (12) face the measuring wheel (1). A coil (7) surrounds the magnet core (6), at which coil (7) a pulsating voltage can be picked off with a frequency proportional to the number of revolutions of the measuring wheel (1), outside the area of the pole shoe (10) end portions (12) facing the measuring wheel (1). The thickness of the pole shoes (10) is increased by additional magnetic material (11) so as to increase the pulsating voltage which can be picked off at the coil (7).
