Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A headlight for a power vehicle, comprising a housing mountable on a body of a vehicle; a frame provided to support a reflector with a lamp and arranged in said housing, said frame being turnable in a horizontal and a vertical direction; means for turning said frame in the horizontal and the vertical direction and including a rotary part axially secured in said housing, a turning part articulately connectable with said frame, and a deflecting mechanism which couples said parts with one another, said deflecting mechanism including a cable shaft and an angular transmission.
Claim 2
Dependent Claim
94 words
A headlight for a power vehicle, comprising a housing mountable on a body of a vehicle; a frame provided to support a reflector with a lamp and arranged in said housing, said frame being turnable in a horizontal and a vertical direction; means for turning said frame in the horizontal and the vertical direction and including a rotary part axially secured in said housing, a turning part articulately connectable with said frame, and a deflecting mechanism which couples said parts with one another, said deflecting mechanism including a cable shaft and an angular transmission.
Claim 3
Dependent Claim
33 words
A headlight as defined in claim 1, wherein said angular transmission is formed as a bevel gear transmission and includes a driving bevel gear and a driven bevel gear both having straight teeth.
Claim 4
Dependent Claim
39 words
A headlight as defined in claim 2, wherein said driving bevel gear has an axis, said driven bevel gear having also an axis, said axes of said bevel gears intersecting one another and enclosing a right angle there between.
Claim 5
Dependent Claim
54 words
A headlight as defined in claim 2, wherein said housing has an inner wall provided with a sleeve which serves as a pivot bearing, said turning part has a nut, said driving bevel gear having a pin which is pivotally supported in said sleeve and also a threaded pin which cooperates with said nut.
Claim 6
Dependent Claim
57 words
A headlight as defined in claim 2, wherein said housing has an inner wall; and further comprising a bearing cover, said inner wall and said bearing cover together forming a ring groove, said driving bevel gear having a collar, said bending shaft also having a collar, said collars being supported and axially secured in said ring groove.
Claim 7
Dependent Claim
59 words
A headlight as defined in claim 2; and further comprising a bearing cover having an opening, said driving bevel gear having a bearing pin with an end shoulder, said bearing pin cooperating with said opening of said bearing cover so that said end shoulder provides a predetermined arrangement of said driving and driven bevel gears relative to one another.
Claim 8
Dependent Claim
30 words
A headlight as defined in claim 2; and further comprising means for form-locking plug connection of said bending shaft with said driving bevel gear and also with said rotary part.
Claim 9
Dependent Claim
42 words
A headlight as defined in claim 7, said rotary part having a pin, said means for plug coupling including a bush with an inner profiled opening surrounding said bending shaft and also including a profiled pin which extends into said inner opening.
Claim 10
Dependent Claim
32 words
A headlight as defined in claim 1, wherein said driving bevel gear has an inner profiled opening, said profiled pin being introduced into said inner profiled opening of said driving bevel gear.
Claim 11
Dependent Claim
