Description

The invention relates to a cover fitting for pivotally attaching a cover to a furniture body. The cover fitting has a base element for mounting the cover fitting on a side wall of the furniture body, the base element having a contact surface for contacting a side surface of the side wall. Furthermore, the cover fitting has a front connection element for mounting a cover element on the cover fitting, as well as a swivel arm which is fastened to the base element about a first body axis and to the front connection element about a first cover axis.

Such a cover fitting is for example from the DE 92 05 039 U1 known, which shows a support for holding a lid with respect to a body, the lid being movably connected to the body by a hinge. A fastening element is attached to the body, as well as to the lid, which are connected to one another via a connecting strut. The connecting strut is articulated in each case about an axis running parallel to the pivot axis of the hinge. The fastening element with which the support is fastened to the body has a fastening plate which has two fastening bores, through which a fastening screw is passed in each case. The mounting plate is connected to a side wall of the body using the mounting screws.
