Abstract: A change-speed transmission which includes an input shaft and an output shaft which are drivingly connected by a forward and rearward planetary gear system. The forward planetary gear system includes two planetary gears one of which meshes merely with a sun gear with the other planetary gear meshing with a further sun gear as well as with a ring gear. The planetary gears are carried by a double carrier which is drivingly connected with one transmission member of the rearward planetary gear system with the ring gear being drivingly connected with another member of the rearward planetary gear system by way of respective torque transmitting coupling trains. A change-speed clutch for producing a direct transmission of the rearward planetary gear system is operatively connected with the double carrier which is also drivable through a gear shifting clutch by way of the input shaft.

Abstract: A bumper for motor vehicles which is displaced in the vehicle longitudinal direction in case of an impact and which is provided with end portions laterally drawn about the vehicle, rigidly connected with the bumper center portion and extending approximately parallel to the vehicle outer surfaces. For purposes of longitudinally guiding the end portions at a distance from the vehicle outer surface, mounting brackets are rigidly connected to each end portion and have free which engage guide members projecting from the vehicle outer surface. A support part of each end portion terminates at a distance from an associated wheel casing cutout and includes on its top side a cover member rigidly connected to the end portion and the remaining area of the end portion is covered by a downwardly projecting apron. In case of a unilateral yielding of the bumper, the apron at first engages a deflection edge of the guide member and then is guided along the same past the wheel while being bent.

Abstract: A reel arrangment for automatic safety belts of motor vehicles which include a roller rotatably mounted in a housing with the roller being subjected to the action of a spring in such a manner that the spring counteracts a withdrawal of the belt. A locking device is provided for locking the roller at high belt forces with a drag disk being mounted eccentrically with respect to a gear nonrotatably connected to the roller. The drag disk includes an engagement arrangement on a bearing surface thereof which cooperates with the gear in a belt take-up direction and is subject to the action of an additional spring in the belt extraction direction. A stop is provided on the reel housing for delimiting the rotational movement of the drag disk with the stop cooperating with two matching stops on the spring-loaded drag disk. The reel housing includes a curved control and guide track or surface which cooperates with a guide pin on the drag disk.

Abstract: A motor vehicle encompassing a chassis which includes a front and rear axle and a vehicle body which is supported upon the chassis by at least two connecting parts in such manner that the body may move in a translatory manner with respect to the chassis while being capable of pivoting about an axis located in the driving direction. Additionally, the support of at least one of each wheels springs is coordinated between the corresponding axle and the vehicle body. The connecting part includes a support column which, at its upper end, is elastically connected to the vehicle body by a substantially central bearing support and, at its lower end, is supported upon the chassis by several bearing supports.
