Abstract

An arrangement is provided for opening and closing an opening in a covering surface of an interior trim piece in a vehicle via an adjustable cover element. The cover element has two parallel, spaced-apart racks which extend in the adjusting direction of the cover element and each mesh with an associated toothed wheel. The toothed wheels are rotatably mounted on a frame element connected to the interior trim piece and are interlinked by a rotatingly driven shaft; at least one toothed wheel is connected to the shaft for conjoint rotation therewith. The cover element is adjustable relative to the frame element and thus to the opening as a result of a rotation of the toothed wheels that mesh with the racks. Preferably, the cover element slides under the covering surface of the interior trim piece, delimiting the opening, when the opening is opened.

Claims

1. An arrangement for opening and closing an opening provided in a covering surface of an interior trim piece in a vehicle, in particular a motor vehicle, the arrangement comprising:

an adjustable cover element formed by a flat element and being movable from a closed position, in which the cover element covers the opening, to an open position, in which the cover element opens the opening by movement of the same in reverse; and

two parallel, spaced-apart racks arranged on the adjustable cover element that extend in an adjusting direction of the cover element and each mesh with an associated toothed wheel,

wherein the toothed wheels are rotatably mounted on a frame element, connected to an interior trim piece and are interlinked by a rotatingly driven shaft,

wherein at least one toothed wheel is connected to the shaft for conjoint rotation therewith, and

wherein the cover element is adjustable relative to the frame element and thus to the opening as a result of a rotation of the toothed wheels that mesh with the racks.

2. The arrangement according to claim 1, wherein the cover element slides under the covering surface delimiting the opening of the interior trim piece when the opening is opened.

3. The arrangement according to claim 1, wherein the racks have a congruent rolling contour, rolling on toothed wheels, and wherein the rolling contour either:

is formed by a first straight rack section, which changes into a second curved rack section formed by a sector of an internally toothed spur wheel, or

is formed by a first curved rack section, which is formed by a sector of an internally toothed spur wheel and changes into a second curved rack section, formed by a sector of an internally toothed spur wheel, wherein a pitch circle diameter of the first rack section is selected to be greater than a pitch circle diameter of the second rack section.

4. The arrangement according to claim 3, wherein the rack sections are arranged on the cover element such that in the closed position of the cover element the second rack section is engaged with the toothed wheel, whereas in the open position of the cover element the first rack section is engaged with the toothed wheel.

5. The arrangement according to claim 1, wherein a front and rear guide pin each, when viewed in the adjusting direction of the cover element, are arranged bilaterally on the same, which guide pins are positively guided slidably in a guide groove of the frame element.

6. The arrangement according to claim 5, wherein the guide groove is formed by a front and rear guide groove section.

7. The arrangement according to claim 6, wherein the guide groove sections are formed on each side separated from one another.

8. The arrangement according to claim 7, wherein the guide groove sections on each side have such a course that proceeding from the closed position of the cover element, during the opening process it is first tilted on the toothed wheel side by a specific angle “

α

”

toward the toothed wheel and guided obliquely in a direction of toothed wheel and lastly taken along a straight line or a substantially straight line.

9. The arrangement according to claim 8, wherein on each side the guide groove sections have such a course that the end of the cover element, the end now facing the toothed wheel in the open position of the cover element, is inclined by a specific angle “

β

”

to the straight line.

10. The arrangement according to claim 1, wherein the interior trim piece is an instrument panel of the vehicle.

11. The arrangement according to claim 1, wherein the arrangement is adapted to cover a head-up display.
