Abstract
Abstract A backlite assembly for an automotive vehicle with a signaling system includes a backlite panel, an illumination system positioned at one edge of the panel for selectively introducing light into the interior of the panel whenever the signaling system is energized, and a refractive surface integrated with the panel for refracting the light emitted by the illumination system so that light will be emitted from the backlite in a pattern recognizable as a signal. The backlite assembly may include turn signaling capability and brakelight function, as well as a hazard warning signal function.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
71 words
A backlite for an automotive vehicle with a signaling system, said backlite comprising: at least one backlite panel; illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel whenever said signaling system is energized; and refraction means integrated with said panel for refracting said light so that said light will be emitted from said backlite in a pattern recognizable as a signal.
Claim 2
Dependent Claim
71 words
A backlite for an automotive vehicle with a signaling system, said backlite comprising: at least one backlite panel; illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel whenever said signaling system is energized; and refraction means integrated with said panel for refracting said light so that said light will be emitted from said backlite in a pattern recognizable as a signal.
Claim 3
Dependent Claim
47 words
A backlite according to claim 1 further comprising reflective means applied about the edges of said panel, whereby light introduced into the interior of said panel by said illuminating means will be reflected away from said edges, so as to intensify the light emitted from said panel.
Claim 4
Dependent Claim
52 words
A backlite according to claim 1 wherein said illumination means comprises an electric light assembly including a bulb and a receptacle for said bulb, with said bulb extending from said receptacle in such a location that said bulb will emit light edgewise into said backlite panel whenever said signaling system is energized.
Claim 5
Dependent Claim
23 words
A backlite according to claim 1 wherein said refraction means comprises a scarified surface integrated into a localized area of said backlite panel.
Claim 6
Dependent Claim
14 words
A backlite according to claim 1 wherein said signaling system comprises a brakelight system.
Claim 7
Dependent Claim
15 words
A backlite according to claim 1 wherein said signaling system comprises a turn signaling system.
Claim 8
Dependent Claim
16 words
A backlite according to claim 1 wherein said signaling system comprises a hazard warning signal system.
Claim 9
Dependent Claim
106 words
A brakelight system for an automotive vehicle with a backlite and a braking system, said brakelight system comprising: a refracting surface integrated into a localized area of said backlite panel; illumination means comprising an electric light assembly including a bulb and a receptacle for said bulb, with said bulb extending from said receptacle in such a location that said bulb will emit light edgewise into said backlite panel; and means for lighting said bulb when said braking system of said automotive vehicle is energized, whereby said light will be refracted by said refracting surface and emitted from said backlite in a pattern recognizable as a brakelight.
Claim 10
Dependent Claim
106 words
A brakelight system for an automotive vehicle with a backlite and a braking system, said brakelight system comprising: a refracting surface integrated into a localized area of said backlite panel; illumination means comprising an electric light assembly including a bulb and a receptacle for said bulb, with said bulb extending from said receptacle in such a location that said bulb will emit light edgewise into said backlite panel; and means for lighting said bulb when said braking system of said automotive vehicle is energized, whereby said light will be refracted by said refracting surface and emitted from said backlite in a pattern recognizable as a brakelight.
Claim 11
Dependent Claim
215 words
A multi-section backlite for an automotive vehicle with braking and turn signaling systems, said backlite comprising: a first backlite panel, constituting the center section of said backlite, comprising: illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel whenever said braking system is energized; and refraction means associated with said panel for refracting said light so that said light will be emitted from said panel in a pattern recognizable as a brakelight whenever said braking system is energized; second and third backlite panels adjoining said center section and constituting the outboard sections of said backlight, with each of said panels comprising: illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel when said turn signaling system is energized; and refraction means associated with said panel for refracting light so that said light will be emitted from one of said panels in a pattern recognizable as a turn signal whenever said turn signaling system is energized; and means for isolating each of said panels from the remaining panels so that light introduced into the interior of any one of said panels by the illuminating means associated with said panels will not enter the interior of the remaining panels.
Claim 12
Dependent Claim
215 words
A multi-section backlite for an automotive vehicle with braking and turn signaling systems, said backlite comprising: a first backlite panel, constituting the center section of said backlite, comprising: illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel whenever said braking system is energized; and refraction means associated with said panel for refracting said light so that said light will be emitted from said panel in a pattern recognizable as a brakelight whenever said braking system is energized; second and third backlite panels adjoining said center section and constituting the outboard sections of said backlight, with each of said panels comprising: illumination means positioned at one edge of said panel for selectively introducing light into the interior of said panel when said turn signaling system is energized; and refraction means associated with said panel for refracting light so that said light will be emitted from one of said panels in a pattern recognizable as a turn signal whenever said turn signaling system is energized; and means for isolating each of said panels from the remaining panels so that light introduced into the interior of any one of said panels by the illuminating means associated with said panels will not enter the interior of the remaining panels.
Claim 13
Dependent Claim
49 words
A multi-section backlite according to claim further comprising reflective means applied about the edges of each of said panels, whereby light introduced into the interior of said panels by said illuminating means will be reflected away from said edges, so as to intensify the light emitted from said panels.
