Abstract
Abstract A headlamp assembly includes a headlamp mounted to tilt in a vertical plane. An adjustment mechanism for varying the angle of tilt consists of a pivoted lever connected to the headlamp through a push/pull rod, a Bowden cable mechanism one end of the cable of which is connected to the lever and a linearly slidable block to which the other end of the cable is connected. The block is adjusted by a screw threaded rod mounted for rotational adjustment which engages in a threaded bore in the block.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
220 words
An adjustable headlamp assembly for a motor vehicle comprising a headlamp, means for mounting the headlamp for tilting movement about a first axis extending normally to the direction in which the headlamp is focussed, resilient means for biassing the headlamp in one direction of tilt about said axis and a Bowden cable mechanism for pulling the headlamp in the opposite direction, said Bowden cable mechanism having an outer sheath with opposite ends, and an inner cable with opposite ends, means for anchoring the ends of the sheath against movement, one end of the inner cable being connected to the headlamp at a location spaced from the axis about which the headlamp tilts and the other end of the inner cable being connected to an adjustment device disposed remote from the headlamp and adapted to be operated from the interior of the motor vehicle for adjusting the position of the inner cable with respect to the outer sheath, the adjustment device comprising an anchorage fixed on the cable, a mounting for the anchorage for supporting the anchorage for linear sliding movement so as to move the cable linearly and screw means engaged with the anchorage for adjusting the position of the anchorage with respect to the mounting with the headlamp being adjusted in relation to the rotation of the screw means.
Claim 2
Dependent Claim

An adjustable headlamp assembly for a motor vehicle comprising a headlamp, means for mounting the headlamp for tilting movement about a first axis extending normally to the direction in which the headlamp is focussed, resilient means for biassing the headlamp in one direction of tilt about said axis and a Bowden cable mechanism for pulling the headlamp in the opposite direction, said Bowden cable mechanism having an outer sheath with opposite ends, and an inner cable with opposite ends, means for anchoring the ends of the sheath against movement, one end of the inner cable being connected to the headlamp at a location spaced from the axis about which the headlamp tilts and the other end of the inner cable being connected to an adjustment device disposed remote from the headlamp and adapted to be operated from the interior of the motor vehicle for adjusting the position of the inner cable with respect to the outer sheath, the adjustment device comprising an anchorage fixed on the cable, a mounting for the anchorage for supporting the anchorage for linear sliding movement so as to move the cable linearly and screw means engaged with the anchorage for adjusting the position of the anchorage with respect to the mounting with the headlamp being adjusted in relation to the rotation of the screw means.
Claim 3
Dependent Claim
60 words
An assembly as claimed in claim 1, wherein the screw means for adjusting the position of the cable anchorage comprise a threaded rod rotatably supported on the mounting for rotation but against axial movement, the rod engaging in a threaded aperture in the cable anchorage so that rotation of the rod adjusts the cable anchorage with respect to the mounting.
Claim 4
Dependent Claim
31 words
An assembly as claimed in claim 1 wherein the adjustment device includes an adjustable stop for limiting the extent of axial movement of the cable anchorage with respect to the rod.
Claim 5
Dependent Claim
19 words
An assembly as claimed in claim 3 wherein the adjustable stop comprises a lock nut mounted on the rod.
Claim 6
Dependent Claim
25 words
An assembly as claimed in claim 3 wherein the adjustment stop comprises a lock nut or a pair of lock nuts mounted on the rod.
Claim 7
Dependent Claim
22 words
An assembly as claimed in claim 2 wherein a knob is provided on the threaded rod for rotational adjustment of the rod.
Claim 8
Dependent Claim
33 words
An assembly as claimed in claim 1 wherein said one end of the cable is connected to a lever mechanism having a push/pull rod which is in turn pivotally connecting to the headlamp.
Claim 9
Dependent Claim
31 words
An assembly as claimed in claim 7 wherein the push/pull rod is connected to the headlamp by a ball formed on the rod engaging in a socket on the headlamp assembly.
Claim 10
Dependent Claim
31 words
An assembly as claimed in claim 1 comprising a plurality of headlamps each having a Bowden cable mechanism as aforesaid connected to a single adjustment device for adjusting the headlamps simultaneously.
Claim 11
Dependent Claim
50 words
An assembly as claimed in claim 1 comprising two pairs of headlamps, the headlamps of each pair being connected to tilt together and a Bowden cable mechanism being connected to each pair of headlamps, the two Bowden cable mechanisms being connected to a single adjustment device for adjusting the headlamps.
