Definitions
- the invention relates to a remotely operable setting system for an aperture Vehicle headlights with an electrical adjustment device through which the aperture arranged between a reflector and a lens of one Low beam is adjustable into a high beam position, with a Actuating device which for inactive electrical adjustment device automatic adjustment of the aperture in the low beam position, and with a Holding device that serves to hold the aperture in the low beam position.
- the Vehicle headlights have a headlight housing in which at least one optical system is used.
- the optical system consists of one ellipsoidal reflector, a lens and an adjustable aperture.
- a light source is arranged inside the focal point of the ellipsoidal reflector, while the outer focal point of the ellipsoidal reflector and the adjustable aperture between the reflector and the lens.
- the lens and the adjustable screen are attached to a frame-like support element, which is attached to the front edge of the reflector.
- the aperture is arranged below the optical axis of the reflector and on the Support element around a horizontal and transverse to the optical axis Swivel axis.
- One at the back of the ellipsoidal Reflector arranged electrical adjustment device is from one electromagnetic actuator formed.
- the electromagnetic actuator has one Solenoids on, through which the panel can be pivoted about the axis.
- the electrical adjustment device is via a rod-shaped lifting element, which runs underneath the reflector, articulated with a swivel arm connected.
- the aperture is opposed by the electrical adjustment device By virtue of an automatic control device into a high beam position pivotable.
- the adjusting device is below the frame-like Carrier element arranged and by a helical tension spring formed with an end portion at the front edge portion of the Carrier element and with the other end portion at the hinge point is attached, which is between the lifting element and the swivel arm.
- the adjustable cover is plate-shaped and stands in hers Low beam position vertically, while the aperture in its high beam position Lens is pivoted out and from the light rays reflected by the reflector the light source is pivoted out.
- inactive or defective electrical Adjustment device ensures that the aperture by the force of the tension spring automatically swivels from its high beam to the low beam position and is automatically held in the low beam position.
- the aperture is in operation from its low beam position only held vibration-free when the Tension spring strong because of a sufficiently large tensile force is dimensioned.
- the higher the tractive force the greater the electromagnetic actuator of the electrical adjustment device be dimensioned.
- To securely hold the cover in the low or high beam position to get the electromagnetic actuator with an additional Permanent magnets can be equipped.
- the electromagnetic actuator at Swiveling the aperture counteract the force of the permanent magnet and must therefore be appropriately large.

- a holding spring in the low beam position of the aperture a holding surface rests automatically on a contact surface of the diaphragm. After adjusting the aperture from the high beam to the low beam position the retaining spring automatically holds the cover against the stop of the assembly. Due to the holding force of the retaining spring, the cover is secure against vertical Vibrations held, which occur when the vehicle is driving, held.
- the swiveling diaphragm which starting from its axis, towards the optical axis a long arm and into the other direction has a short arm at the free end portion of the long arm can be held by the holding device on the carrier element, wherein the retaining spring with the holding surface on a horizontal central plane of the reflector sloping and downward contact surface of the Aperture can be applied resiliently and one to the horizontal central plane of the reflector has inclined and upward sliding surface on which the Aperture when adjusting from the high beam to the low beam position with the free end portion of her long arm slides along until the retaining spring with the Holding surface rests resiliently on the contact surface of the panel.
- the low beam position is adjustable and is still safe in the low beam position held.
- the size of the force is due to the position of the contact surface of the panel determinable which is necessary to the aperture from the low beam position swing away. It is also the location of the sliding surface of the retaining spring depending on the force to swing the aperture from the high beam to the Low beam position is necessary.
