Rear-light assembly for motor vehicle

Claim 1

In a built-in type rear-light assembly at a transition from a rear surface to a side surface, said rear-light assembly being of a type having: a light-diffuser, which in a built-in position when viewed in a driving direction from the rear of a motor vehicle, projects substantially a trapezoidal shape and when viewed from a side of the motor vehicle projects substantially a rectangular shape, with the light-diffuser extending in a curve at the transition from the rear surface into the side surface; a light-assembly housing including respectively a reflector for each of a blink light, brake light, taillight, fog taillight, and reverse-drive light with light from the blink light exiting through an upper light-diffuser portion and light from the brake light, taillight and fog taillight exiting through adjacent light-diffuser portions at a common lower height level, with taillight and a fog taillight light-diffuser portions extending in a substantially planar surface while the brake-light light-diffuser portion at least partially lies in the curve at the transition from the rear surface to the side surface, with the taillight light-diffuser portion having a rearward beamer comprised of foreign-light-reflecting rear-beam prisms arranged in lines which alternate with lines which are occupied by vertically extending cylindrical lenses; with areas of the light diffuser extending to the sidewall of the motor vehicle being covered by an approximately uniformly-spaced edge portion of the housing bowed back at a substantially obtuse angle which is light reflective; the improvement wherein: a) the blink-light extends over an entire width of the rear-light assembly; b) the reflector for the blink light extends over the entire width of the rear surface of the light diffuser portion for the blink light and substantially into a side surface area of this light-diffuser portion; c) the linear rear-beam prisms and the cylinder lenses therebetween in the lower region of the light-diffuser extend from edge to edge substantially over the entire width of the light-diffuser; d) the linear rear-beam prisms in those portions of the light diffuser extending sidewardly from the reflectors for the taillight and rear fog light being made to be optically ineffective; e) a rear-light assembly includes a middle portion for creating a backing light creating portion located between an upper blink-light creating portion and lower brake-, tail-, and fog-light creating portion; f) a reflector for creating the backing light extends from an inner side edge of the rear-light assembly to a beginning of the curved shaped transition of the light diffuser from its rear surface to its side surface; g) a portion of the light diffuser covering a reflector for backing light, and being of a size corresponding to light exiting from this reflector, is provided with linear opaque strips; h) lines lying between the opaque strips are occupied by vertically-extending cylindrical lenses; i) the opaque strips have approximately the same color as the diffuser portions for the brakelight, taillight, and fog taillight; j) the light-diffuser portion lying to the side of, but near, the backing light creating portion has an optical structure corresponding to the brake-light light-diffuser portion positioned thereunder; and k) a portion of the light diffuser lying to a side of the backing light-diffuser portion and above the brake-light light-diffuser portion is backed up by a sidewardly enclosed reflector.
