Description

The The invention relates to a window channel strip for leadership and for sealing the window pane of the door of a motor vehicle of Outside according to the generic term of claim 1.

As is known, the window shafts of motor vehicle doors are to be sealed against external atmospheric influences, the seal simultaneously serving to guide the window pane as it moves out of and into the window shaft. According to the DE 197 11 487 For this purpose, suitable sealing profiles made of elastomeric material have become known, which comprise a sealing area and an integral fastening area. The fastening region consists of a U-shaped base body with an outer leg and an inner leg with intermediate web element and has a reinforcing element, which is formed only in the outer leg and in a portion of the web element, so that the inner leg with bias is charged. Finally, the base body has at least one sealing lip, which is arranged via a connecting web on the outer leg.

A generic window channel strip for guiding and sealing a window of a door of a motor vehicle is in the JP 02 175 323 A disclosed. The window channel strip has a formed as a sealing profile body with a voltage applied to the window glass sealing lip. By means of its essentially U-shaped region, which has a clamp-like reinforcing element, the main body encloses the facing door flange of the motor vehicle door in a sealing manner and has a web formed in a T-shaped manner at its lower end.

From the DE 42 24 486 C2 is a side door for motor vehicles with a retractable disc and arranged between the door body and the outside of the disc seal known. The disc opposite end portion of the seal is in this case held in a form-fitting manner in a seal carrier.

Though is the sealing effect of such a prior art training a Window slot trim satisfactory, however, is how the experience has shown, the theft protection inadequate, since the relatively simple Installation of such a window slot bar brings with it that this is also relatively easy to remove from unauthorized persons from the outside, what the unauthorized access to the door closing unit and thus facilitates the vehicle interior. this is also valid for others known window slot strips of this type.

The Invention is therefore based on the object to remedy this situation by a new design of such a window channel strip.

These Task is in accordance with the invention by the features of claim 1 solved.

Further Features of the invention will become apparent from the dependent claims.

By the two-part design according to the invention the window channel strip in base body and plastic molding can These can be optimally adapted to the respective tasks more easily than before with significant material savings as a result of reduced material usage. This is especially true for the high quality EPDM rubbers and for the necessary to achieve the required spring property metal inserts for the metallic reinforcing member at the base body. The plastic molding to be joined is without metallic reinforcement and can be enough with one long bridge for the purpose of firm connection with a sheet metal part of the force vehicle door - z. B. through clips - provided become. In particular, however, the attachment of the window slot strip as a result of the entanglement between body and molding deeper than usual laid and opposite the plane of the door flange are arranged offset inwards, so that a disassembly of the Window slot molding from the outside considerably more difficult. This is the access to the door closing unit the motor vehicle door better than hitherto, which has the effect of increasing theft protection.

One embodiment The invention is described below with reference to a single figure in the Drawing illustrated embodiment described.

From a motor vehicle door 10 a motor vehicle, not shown, in the single figure, only an outer panel 11 and an inner panel 12 represented, which are interconnected at one end by a flat flange and there extending over the width of the door so-called. Türflansch 14 form. A made of EPDM rubber, trained as a profile strip body 16 and a plastic molding 17 , are by means of a locking connection 18 non-positively and positively connected with each other and together form a window channel strip 20 ,

The main body 16 has an approximately U-shaped area with a sealing finger 22 having outer thighs 23 and also a sealing finger 24 having inner thighs 26 , Both legs define a downwardly open slot 28 ,

The inner surface of the thigh 23 wearing sealing fingers 29 and the inner surface of the thigh 26 wears sealing knobs 31 , The slot 28 is the door flange 14 assigned and surrounds this springy. For this purpose, the base body in this area has a U-shaped resilient clip-like metal reinforcement element 34 on, extending to the T-shaped bridge 35 of the basic body 16 extends. Once the main body 16 with his slot 28 on the door flange 14 is deferred, this is held by the spring force inherent in this leg, sealing the window slot in the deferred position.

This deferred position of the main body is due to the positive connection of the latching connection 18 between the main body 16 and on the inner panel 12 the motor vehicle door attached plastic molding 17 fixed. For this purpose, the plastic molding 17 a clamp 38 and 39 carrying, the T-shaped web 35 of the basic body 16 facing clamp-shaped area; the clamp arms 38 and 39 form an opening 40 that is the T-shaped bridge 35 encloses positively. Here, the clamping arms grip behind the abutment surfaces 42 and 43 of the T-shaped bridge 35 , so that a positive and non-positive locking connection between the base body 16 and plastic molding 17 is ensured. The area facing away from the latching connection 44 of the plastic molding 17 is formed tab-shaped and serves the said attachment of the plastic molded part 17 on the inner panel 12 the vehicle door by means of clips 45 in a known manner.

For receiving the locking connection 18 on the inner panel 12 the motor vehicle door 10 this is in the area of the clamping arm 39 opposite the plane of the door flange 14 offset inwardly and forms in this area a form-fitting subsequent to the locking connection indentation 46 , In this way, the window slot bar is held immovable and secure in its plugged and locked position and can not be brought out of the occupied position by unauthorized persons from the outside. An access from the outside to the door closing unit by removing the window slot bar has therefore become almost impossible.
