Vehicle roof cover having a frame part

Abstract

A cover for closing a vehicle surface opening is provided which has a frame part secured to the underside of the cover on one side at a frame part securing section by an application of plastic foam on the cover, and which contacts the underside of the cover on the other side at a free section of the frame part via at least one spacer. The frame part may also include at least one filling opening on the free section thereof for introducing a reactive plastic material forming the spacer, and the plastic material introduced through the filling opening into a gap between the free section of the frame part secured to the cover and the underside of the cover retains the free section of the frame on the underside of the cover in a positioned and/or fixed manner as a spacer after reacting or curing.

14. The cover of claim 1, wherein the spacer is formed by plastic material which fills only a region closely surrounding the filling opening.

Description

BRIEF DESCRIPTIONS OF THE DRAWINGS

(1) The invention is explained in more detail below on the basis of one exemplary embodiment of a cover according to the invention with reference to the drawing, in which:

(2) FIG. 1 shows a lateral portion of a cover of a vehicle roof with a frame part attached to the cover bottom side in a cross-sectional view;

(3) FIG. 2 shows a portion of the frame part in an isometric view;

(4) FIG. 3 shows a view from below of a cover frame of the cover which has a frame part on each of its two lateral longitudinal frame portions in an isometric view,

(5) FIG. 4 shows a lateral portion of a cover of a vehicle roof with a frame part attached to the cover bottom side in a cross-sectional view having a spacer formed from a plurality of layers.

DETAILED DESCRIPTION

(6) A cover 1 of an openable vehicle roof of a vehicle, such as e.g. a passenger car, is provided for example for closing a roof opening and can be raised out of a closed position, which closes the roof opening, and can be adjusted or pivoted out e.g. at least into a ventilation position. The cover 1 is for example a cover of a tilt-and-slide roof, a spoiler roof or an externally guided sliding roof and is in particular a glass cover or produced from a transparent plastic.

(7) On the edge side, the cover 1 has a foamed-on structure 2 as a plastic frame or plastic enclosure, which foamed-on structure is formed in particular from polyurethane (PU), is formed preferably in an encircling manner on the cover 1 and is expediently formed with a downwardly projecting screen 4 at each of the two longitudinally running side edges 3 of the cover 1.

(8) An elongate frame part 5 is arranged on the cover inner side or cover bottom side 6 so as to run inwardly from the lateral cover edge 3 and along the cover edge 3. A frame part fixing portion 7, which is on the outside, of the frame part 5 is embedded in the foamed-on structure 2 and fixed to the cover bottom side 6 by means of the foamed-on structure 2. A contact portion 8 of the frame part 5 adjoins the frame part fixing portion 7 inwardly in a transverse direction and bears against the cover bottom side 6 with a seal 9, such as e.g. a microcellular rubber layer, in between. In the foaming tool, during the foaming of the foamed-on structure 2, the seal 9 seals off a narrow gap 10 between the contact portion 8 and the cover bottom side 6 and thus prevents foam of the foamed-on structure 2 from escaping through this gap 10.

(9) Furthermore, adjoining the contact portion 8, the frame part 5 has a frame part free portion 11 which is expediently spaced apart from the cover inner side 6 and which preferably ends in a web 12, which extends in a manner directed away from the cover 1 and on which is formed a receptacle 13, such as for example an opening, for a mounting or actuating device of the cover 1, such as e.g. a deployment mechanism.

(10) Provided on the frame part 5 is at least one spacer 14, which holds the frame part free portion 11 of the frame part 5 at a spacing from the cover bottom side 6. On one side, the spacer 14 is arranged in the region of a filling opening 15 of the frame part 5, which filling opening is preferably arranged close to the inner edge 16 of the frame part 5 in a spacer frame portion 17 which is spaced apart from the cover bottom side 6. The filling opening 15 is formed e.g. as round or elongate in the longitudinal direction of the frame part 5 and is arranged e.g. in a round or elongate depression 18 of the frame part 5 or of the spacer frame portion 17, which depression is formed as a bulge remote from the cover bottom side 6. The spacer 14 is a plastic part which is foamed or injection molded from a plastic material, such as e.g. from polyurethane or an adhesive. The spacer 14 is formed by introducing or injecting a plastic compound or adhesive through the filling opening 15 in a gap 19 between the frame part 5 and the cover bottom side 6. The introduced reactive plastic material comes to lie against the cover inner side 6 and the spacer frame portion 17 and partially, largely or completely fills the depression 18. The depression 18 thus delimits the expansion of the introduced plastic material. Depending on the plastic material used, after the plastic material has been fully reacted or cured, the spacer 14 is held in a form-fitting manner at the filling opening 15 and can additionally adhere or be adhesively bonded to the cover inner side 6 and the spacer frame portion 17 if the plastic material has a corresponding adhesive property. The spacer 14 damps vibrations of the frame part free portion 11 in relation to the cover 1 or prevents such vibrations from occurring.

(11) FIG. 3 shows the foamed-on structure 2 configured as a plastic frame 20 which is molded in an encircling manner on the cover inner side or cover bottom side 6 of the cover 1 (the cover is not illustrated) and to the two longitudinal portions 21 of which respectively the frame part 5 is fixed. In this exemplary embodiment, each frame part 5 has two filling openings 15 in associated depressions 18. The frame parts 5 which are produced in particular from a metallic material can be integrated separately in the plastic frame 20 or are parts or portions of an encircling reinforcing frame.

(12) The individual features of the invention which are disclosed in the description and with reference to the exemplary embodiment as well as in the figures can be combined in any desired technically expedient arrangements and configurations with the subject matter of the invention in its general form.
