Abstract

A flap arrangement for a motor vehicle is disclosed which includes a flap, and more specifically a tank flap, a plunger on which the flap is rotatably mounted, and a base, and more particularly a tank trough on which the plunger is shiftably mounted in a projection direction (A).

First claim

What is claimed is:

1. A flap arrangement for a motor vehicle comprising:
a base having a flap border defining an opening formed in the base;
a plunger operably coupled to the base and slidably positionable between a retracted position and an extended position; and
a flap rotatably supported on the plunger such that the flap translates from a closed position away from the flap border to a pivot start position as the plunger moves from the retracted position to the extended position, and rotates from the pivot start position to an open position;
wherein the flap is flush with the flap border to conceal the opening when in the closed position and projects away from the flap border to reveal the opening when in the open position.

2. The flap arrangement according to claim 1 wherein the flap is a fuel filler flap and the flap arrangement further comprises a filler neck disposed within the opening.

3. The flap assembly according to claim 1 wherein the plunder comprises a link member operably coupled to the flap in an articulated manner and coupled to the plunger is guided in a form-fitting manner.

4. The flap arrangement according to claim 1 wherein the plunger comprises a gear for pivoting the flap due to a displacement of the plunger toward the extended position.

5. The flap arrangement according to claim 1 , further comprising a transmission coupling the plunger and the flap such that there is no idle travel for displacing the plunger in a disengaged position toward the extended position without pivoting of the flap.

6. The flap arrangement according to 5 , wherein the transmission comprises a link guide and/or at least one gear wheel.

7. The flap assembly according to claim 6 , wherein the transmission comprises a rack having a toothing and at least one rotatably mounted gear wheel meshing with the rack.

8. The flap assembly according to claim 7 , wherein the gear wheel is rotatably mounted to the base and the rack is fixed to the plunger.

9. The flap assembly according to claim 5 , further comprising a spring mechanism for biasing the plunger in the extended position, the spring mechanism coupled to the transmission for pivoting the flap.

10. The flap arrangement according to claim 1 further comprising a stop for limiting at least one of an input, pivoting out of the flap, and a displacement of the plunger in the extended position.

11. The flap arrangement according to claim 1 , further comprising a spring mechanism for biasing the plunger in the extended position.

12. The flap assembly according to claim 10 , wherein the spring mechanism is arranged in a guide of the plunger to the base.

13. The flap arrangement according to claim 1 , wherein the open position is at least substantially perpendicular to an axis of rotation about which the flap is mounted rotatably on the ram.

14. A flap arrangement for a motor vehicle comprising:
a base having a flap border defining an opening formed in the base;
a plunger operably coupled to the base and slidably positionable between a retracted position and an extended position;
a push-push kinematic mechanism for locking and unlocking the plunger by successively engaging the push-pull mechanism in the retracted position; and
a flap rotatably supported on the plunger such that the flap translates from a closed position away from the flap border to a pivot start position as the plunger moves from the retracted position to the extended position, and rotates from the pivot start position to an open position;
wherein the flap is flush with the flap border to conceal the opening when in the closed position and projects away from the flap border to reveal the opening when in the open position.

15. The flap assembly according to claim 14 , wherein the push-push kinematic mechanism comprises a sliding member and an engaging member.
