Abstract
Abstract Two-piece assembly fixed to inner forward margin of driver's door of vehicle so as to position a horizontal support arm generally parallel to and spaced from auto dashboard, with a terminal abutment arm carried normally overlying the face of the pull knob of headlight pull-push switch-rod when retracted to its (OFF) position. Abutment arm is pivoted or spring-loaded for manual retraction to disengaged position which is automatically restored upon door opening, so that subsequent closing of door will cause abutment arm to axially contact outdrawn switch-rod and press it back to light-off position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A motor vehicle automatic headlight turnoff switch assembly comprising: a support arm having means at one end for attachment to an inner upstanding surface of a horizontally swingable vehicle door in position to locate the unattached end of said arm adjacent the operator's end of a headlight switch-rod which is longitudinally reciprocable between IN and OUT positions, the latter position serving to keep the headlights on, an abutment member carried by the unattached end of said support arm, being movable between alternate positions, (a) axially adjacent the end of the switch-rod when the latter is at IN position, so as to block the switch-rod being drawn to OUT position, and (b) laterally retracted therefrom so as to permit the switch-rod to be drawn to OUT position, said member being biased to normally occupy position (a) and thus automatically to assume such position upon the vehicle door being opened, whereby closing the door causes the abutment member to frictionally abut the switch-rod when OUT positioned and push it to IN position, thereby extinguishing the headlights operated by the switch-rod.
Claim 2
Dependent Claim
178 words
A motor vehicle automatic headlight turnoff switch assembly comprising: a support arm having means at one end for attachment to an inner upstanding surface of a horizontally swingable vehicle door in position to locate the unattached end of said arm adjacent the operator's end of a headlight switch-rod which is longitudinally reciprocable between IN and OUT positions, the latter position serving to keep the headlights on, an abutment member carried by the unattached end of said support arm, being movable between alternate positions, (a) axially adjacent the end of the switch-rod when the latter is at IN position, so as to block the switch-rod being drawn to OUT position, and (b) laterally retracted therefrom so as to permit the switch-rod to be drawn to OUT position, said member being biased to normally occupy position (a) and thus automatically to assume such position upon the vehicle door being opened, whereby closing the door causes the abutment member to frictionally abut the switch-rod when OUT positioned and push it to IN position, thereby extinguishing the headlights operated by the switch-rod.
Claim 3
Dependent Claim
33 words
The switch assembly of claim 1 in combination with a motor vehicle having said switch assembly mounted on a vehicle door in position to operatively contact a longitudinally-reciprocable headlight-connected switch-rod of the vehicle.
Claim 4
Dependent Claim
29 words
A switch assembly according to claim 1 wherein said abutment member is pivotally secured to the support arm for generally vertical movement and is gravity-biased to assume position (a).
Claim 5
Dependent Claim
26 words
A switch assembly according to claim 1 wherein said abutment member is lengthwise displaceable along the support arm and is spring tensioned to assume position (a).
Claim 6
Dependent Claim
49 words
A switch assembly according to claim 3 wherein said abutment member is formed with a transverse offset length and coupling means whereby it may be pivotally secured to the support arm with the offset length alternately toward and away from the axis of the switch-rod when in position (a).
Claim 7
Dependent Claim
20 words
A switch assembly according to claim 4 wherein both said support arm and the displacement abutment arm are concentrically tubular
Claim 8
Dependent Claim
63 words
A switch assembly according to claim 6 wherein said tubular members are mutually telescopically engaged and disposed concentric with a compression spring and are restrained from further longitudinal separation beyond position (a) by an oppositely oriented pair of semi-rigid, elongated loops carried within the telescopic tubes, which loops are medially overlapped and each terminally fastened adjacent an opposite end of the respective tubes.
