Abstract
Abstract A motor vehicle has a pair of vertically tiltable headlamps mounted on the vehicle body. An elongate rod extends horizontally between the two headlamps and is slidable in bushes fixed to the motor vehicle body. The elongate rod is connected at its respective ends to the headlamps by way of respective pairs of links disposed on opposite sides of the rod. One link of each pair is pivotally connected between the rod and the respective headlamp whilst the other rod of each pair is pivotally connected between the rod and the body. Movement of the rod effects simultaneous movement of the headlamps and is effected by a mechanical/hydraulic system linked to a rear axle housing and an engine of the motor vehicle so that headlamp tilting occurs to compensate for tilting of the body under changing conditions of load, acceleration and braking.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A motor vehicle including a vehicle body, a pair of headlamps mounted on said vehicle body for pivotal movement about a horizontal axis, said headlamps being spaced apart transversely of the longitudinal axis of said vehicle body, and means for effecting pivotal movement of said headlamps, said means including an elongate element extending between said headlamps, said elongate elements being slidable transversely relative to said longitudinal axis of said vehicle body and along its own longitudinal axis, said means further including a linkage attached to each end of said elongate element and to an adjacent one of said pair of headlamps, said linkages being arranged so that longitudinal movement of said element causes simultaneous pivotal movement of said headlamps.
Claim 2
Dependent Claim
119 words
A motor vehicle including a vehicle body, a pair of headlamps mounted on said vehicle body for pivotal movement about a horizontal axis, said headlamps being spaced apart transversely of the longitudinal axis of said vehicle body, and means for effecting pivotal movement of said headlamps, said means including an elongate element extending between said headlamps, said elongate elements being slidable transversely relative to said longitudinal axis of said vehicle body and along its own longitudinal axis, said means further including a linkage attached to each end of said elongate element and to an adjacent one of said pair of headlamps, said linkages being arranged so that longitudinal movement of said element causes simultaneous pivotal movement of said headlamps.
Claim 3
Dependent Claim
35 words
The motor vehicle according to claim 1, wherein said means for effecting pivotal movement of said headlamps includes a transducer having a mechanical output operably connected with said element, said transducer having a hydraulic input.
Claim 4
Dependent Claim
54 words
The motor vehicle according to claim 2, wherein said transducer includes a housing within which is disposed a reservoir having a flexible wall, an inlet to said reservoir defining said hydraulic input, and said output comprises a rod extending into said housing and slidable relative thereto in response to flexure of said flexible wall.
Claim 5
Dependent Claim
28 words
The motor vehicle according to claim 1, wherein said elongate element is in the form of a rod which is slidable in bushes relative to said vehicle body.
Claim 6
Dependent Claim
31 words
The motor vehicle according to claim 4, wherein said rod is split intermediate said headlamps and the split ends are connected to a common operating member by means of respective joints.
Claim 7
Dependent Claim
87 words
The motor vehicle according to claim 1, wherein each linkage comprises a pair of links disposed on opposite sides of said elongate element, one of said links being pivotally attached at one of its ends to the respective headlamp and at the other of its ends to the respective end of said elongate element, and the other of said links being pivotally attached at one of its ends to said vehicle body and at the other of its ends to said respective end of said elongate element.
