  • Patent number: 11920629
    Abstract: A method is provided for fitting a snap fit arrangement, as well as a fitting arrangement for fitting the snap fit arrangement for joining a first part with a second part. The snap fit arrangement comprises an engagement hook which is arranged at the first part. The snap fit arrangement comprises a latch element which is arranged at the second part. When the snap fit arrangement closes, the engagement hook deforms elastically and engages into the latch element. In the method, an auxiliary tool is provided. The elastic deformation is caused in the engagement hook by means of the auxiliary tool. The first part is joined to the second part and retracting the auxiliary tool. Retracting causes a spring-back of the elastic deformation in the engagement hook.

  • Patent number: 5055983
    Abstract: A rear-light assembly for a motor vehicle is positioned at a transition from a rear surface (11) to a side surface (12) of the motor vehicle. A light diffuser thereof (1,2) has an exterior surface which extends relatively smoothly into the rear and side surfaces of the rest of the body of the motor vehicle. Light-diffuser portions (17, 18 and 19) for a brake-light reflector (6), a taillight reflector (7), and a fog taillight reflector (8) are provided with linearly arranged exterior-light reflecting rear-beam prisms (20). In a flat area (18, 19) of the light diffuser, which extends over the fog taillight and taillight, the rear-beam prisms are optically effective while at an adjacent area they are made to be optically ineffective. A light-diffuser portion (15) for a backing light reflector (4) is provided with an opaque lattice, or grill, (21, 22) which includes linearly shaped strips (21). This light-diffuser portion is also in an area of the light diffuser which extends substantially planar, or flat.

  • Patent number: 4727458
    Abstract: The invention refers to a motor vehicle projection headlight, where the projection lens is in part covered by a light transmitting plate. The light transmitting plate has edge regions which are of a wider diameter than the lens. An annular light impermeable cover, which surrounds the lens immediately and at a small distance, is disposed at a distance to the edge region of the light permeable plate. The surface of the cover toward the light transmitting plate is of high reflectivity.

  • Patent number: 4586402
    Abstract: A drive for a two-worm extruder has a housing, an electric motor secured to the housing and having a motor output rotatable about a motor axis therein, and a planetary gear transmission in the housing including a sun gear, a ring gear coaxially surrounding the sun gear, and a driven planet gear in mesh between the sun and ring gear. A first output shaft extends axially through the planetary transmission within the ring gear and has an outer end adapted to be secured to one of the worms of the extruder. A second output shaft carried on the sun gear has an outer end adjacent that of the first output shaft and is adapted to be secured to the other worm of the extruder. A force-splitter includes a continuous-mesh gear train connected to the first shaft, to the planet gear, and to the motor output for driving the first shaft and the planet gear from the motor output. At least two further idling planet gears are journaled in the housing and each in mesh between the sun gear and the ring gear.
