IMAGE ACQUISITION ARRANGEMENT OF A MOTOR VEHICLE

Abstract

An arrangement for capturing an image of a space in front of or behind a motor vehicle, the motor vehicle having a motor vehicle windowpane which has an inner surface. The arrangement includes an image acquisition unit and a transparent heating film. The image acquisition unit is mounted on an inside of the motor vehicle windowpane. The image acquisition unit has a field of vision. The transparent heating film is arranged in the field of vision of the image acquisition unit and is attached to the inner surface of the motor vehicle windowpane.

Claims

1. An arrangement for capturing an image of a space in front of or behind a motor vehicle, the motor vehicle comprising a motor vehicle windowpane which comprises an inner surface, the arrangement comprising: an image acquisition unit which is mounted on an inside of the motor vehicle windowpane, the image acquisition unit comprising a field of vision; and a transparent heating film which is arranged in the field of vision of the image acquisition unit and which is attached to the inner surface of the motor vehicle windowpane.

2. The arrangement as recited in claim 1, wherein the transparent heating film is attached to the inner surface of the motor vehicle window pane via a transparent adhesive.

3. The arrangement as recited in claim 1, wherein the transparent heating film comprises a substrate film on which heating conductors are arranged.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention is described in greater detail below on the basis of embodiments and of the drawing in which:

[0009] The FIGURE shows an embodiment of the image acquisition arrangement having a heating film of the present invention.

DETAILED DESCRIPTION

[0010] The present invention provides that a transparent heating film is attached on the inner surface of the motor vehicle windowpane, the transparent heating film being located in the field of vision of the image acquisition unit.

[0011] Such an arrangement for the image acquisition comprises a lens shade having a technically simple construction because it is not used for heating. The motor vehicle windowpane is heated exactly in that area where it tends to fog or ice up so that no heating of other areas of the image acquisition arrangement occurs. Energy is thereby saved.

[0012] A simple and safe attachment is achieved when the heating film is attached to the inner surface of the motor vehicle windowpane with a likewise transparent adhesive.

[0013] An embodiment of the present invention is shown schematically in the drawing which is described in greater detail below.

[0014] The FIGURE shows that an image acquisition arrangement 2 comprising an image acquisition unit 3 is attached on the inner surface or back of a motor vehicle window pane 1, in particular a windshield or a rear window pane. The image acquisition arrangement 2 is closed on its bottom side by a covering 4 which forms a lens shade 5 on its upper side.

[0015] The motor vehicle windowpane 1 has a see-through area 6 through which the field of vision 7 of the image acquisition unit 3 extends. The motor vehicle window pane 1 is covered on its inside in the area of the see-through area 6 by a radiolucent, transparent heating film 8, the heating of which safely prevents fogging, icing and/or the formation of hoar frost on the motor vehicle window pane 1.

[0016] The heating film 8 is attached to the inner surface of the motor vehicle windowpane 1 via a full surface application of a transparent adhesive.

[0017] The present invention is not limited to embodiments described herein; reference should be had to the appended claims.
