Abstract
Abstract An installation actuated by pressure medium for adjusting the inclination of a headlight in relation to the road plane, especially in a motorcycle, with an adjusting cylinder mounted at the frame or the like and operatively connected with the headlight, which pivots the headlight about a cross-axis upon actuation by the pressure medium of the hydraulic brake system, to which the adjusting piston is connected.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
An installation actuated by a fluid pressure medium for adjusting the inclination of a vehicle headlight in relation to the road plane, comprising adjusting cylinder means, on the one hand, arranged at a relatively fixed part of the vehicle and, on the other, operatively connected with the headlight, said adjusting cylinder means being operable to pivot the headlight about a cross axis during actuation of said adjusting cylinder means by the fluid pressure medium, characterized in that the adjusting cylinder means is operatively connected with a hydraulic brake system of the vehicle such that hydraulic fluid of said hydraulic brake system actuates said adjusting cylinder means to pivot the headlight about said cross axis.
Claim 2
Dependent Claim
114 words
An installation actuated by a fluid pressure medium for adjusting the inclination of a vehicle headlight in relation to the road plane, comprising adjusting cylinder means, on the one hand, arranged at a relatively fixed part of the vehicle and, on the other, operatively connected with the headlight, said adjusting cylinder means being operable to pivot the headlight about a cross axis during actuation of said adjusting cylinder means by the fluid pressure medium, characterized in that the adjusting cylinder means is operatively connected with a hydraulic brake system of the vehicle such that hydraulic fluid of said hydraulic brake system actuates said adjusting cylinder means to pivot the headlight about said cross axis.
Claim 3
Dependent Claim
14 words
An installation according to claim 1, characterized in that the vehicle is a motorcycle.
Claim 4
Dependent Claim
21 words
An installation according to claim 1 or 2, characterized in that the relatively fixed part is formed by the vehicle frame.
Claim 5
Dependent Claim
32 words
An installation according to claim 1 or 2, characterized by a line means leading to the adjusting cylinder means which is operatively connected with the hydraulic brake system for the front wheel.
Claim 6
Dependent Claim
21 words
An installation according to claim 4, characterized in that the adjusting cylinder includes piston rod means constructed changeable in its length.
Claim 7
Dependent Claim
23 words
An installation according to claim 5, characterized in that the adjusting cylinder means is held in its normal position by a compression spring.
Claim 8
Dependent Claim
38 words
An installation according to claim 6, characterized in that a valve means is provided which is operable to interrupt the pressure medium connection between the hydraulic brake system and the adjusting cylinder means when the vehicle stands still.
Claim 9
Dependent Claim
24 words
An installation according to claim 1 or 2, characterized in that the adjusting cylinder means includes piston rod means constructed changeable in its length.
Claim 10
Dependent Claim
