Abstract
Abstract A headlamp suitable for a motor vehicle comprises a first component part composed of a reflector and a second component part composed of a lens and a rearwardly projecting spacer, the two component parts being connected together by interleaved peripheral webs and channels which form a labyrinth seal preventing ingress of water, but allowing ventilation. Pivot axes are formed by interengaging partly cylindrical formations along the edges of the webs and channels.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A headlamp having a first component part comprising a lens and a rearwardly projecting spacer, and a second component part comprising a reflector, characterized in that the two component parts each include peripherally corresponding upper, lower and side peripheral edges and labyrinth seal means are interposed between the component parts at the corresponding peripheral edges to provide a ventilating seal thereacross, the labyrinth seal means comprising interleaved webs and channels formed on the corresponding peripheral edges of the component parts such that the labyrinth seal means webs are formed on the peripheral edges of the spacer and the labyrinth seal means channels are formed on the peripheral edges of the reflector, and wherein one of the labyrinth seal means webs includes a partly cylindrical edge and one of the labyrinth seal means channels with which the one web is interleaved includes a partly cylindrical recess engaging the partly cylindrical edge to define a pivot axis.
Claim 2
Dependent Claim
155 words
A headlamp having a first component part comprising a lens and a rearwardly projecting spacer, and a second component part comprising a reflector, characterized in that the two component parts each include peripherally corresponding upper, lower and side peripheral edges and labyrinth seal means are interposed between the component parts at the corresponding peripheral edges to provide a ventilating seal thereacross, the labyrinth seal means comprising interleaved webs and channels formed on the corresponding peripheral edges of the component parts such that the labyrinth seal means webs are formed on the peripheral edges of the spacer and the labyrinth seal means channels are formed on the peripheral edges of the reflector, and wherein one of the labyrinth seal means webs includes a partly cylindrical edge and one of the labyrinth seal means channels with which the one web is interleaved includes a partly cylindrical recess engaging the partly cylindrical edge to define a pivot axis.
Claim 3
Dependent Claim
26 words
A headlamp according to claim 1, wherein the partly cylindrical edge is retained in engagement with the partly cylindrical recess by means of a spring clip.
Claim 4
Dependent Claim
25 words
A headlamp according to claim 1, wherein the spacer is formed as a one-piece component part with a front end panel of a motor vehicle.
Claim 5
Dependent Claim
22 words
A headlamp according to claim 3, wherein the front end panel of the motor vehicle includes a bumper and slats or blinds.
Claim 6
Dependent Claim
226 words
A headlamp having a first component part comprising a lens and a rearwardly projecting spacer and a second component part comprising a reflector characterized in that the two component parts each include peripherally corresponding upper, lower and side peripheral edges and labyrinth seal means are interposed between the component parts at the corresponding peripheral edges to provide a ventilating seal thereacross, the labyrinth seal means comprising interleaved webs and channels formed on the corresponding peripheral edges of the component parts, and wherein some of the labyrinth seal means webs are formed on the upper and lower peripheral edges of the spacer which interleave with some of the labyrinth seal means channels formed on the corresponding upper and lower peripheral edges of the reflector and the remainder of the labyrinth seal means channels are formed on the side edges of the spacer which interleave with the remainder of the labyrinth seal means webs formed on the corresponding side edges of the reflector, one of the labyrinth seal means webs along the upper peripheral edge of the spacer having in its center an arcuate nose and the corresponding labyrinth seal means channel on the reflector having an arcuate cavity in which the nose is received, the nose and the cavity forming a pivotal axis for adjustment of the headlamp and held against one another by a spring clip.
