Description

The present invention relates to a carrier part for fastening lines and / or a head airbag module to a column of a vehicle body according to the preamble of claim 1 and to a vehicle according to claim 13.

Such a carrier part is from DE 199 45 370 B4 known. It is used to fasten electrical cables, a water drainage hose and a head airbag module to an A-pillar of the body of motor vehicles in the roof connection area. The carrier part consists of a base body which can be fastened to the inner sheet metal of the column by means of a clip connection and which accommodates the electrical lines, the water drainage hose and the head airbag module in separate receptacles. Finally, an inner cladding covering the carrier part can be connected to the base body in the manner of a clip.

In the EP 987167 A2 describes an A-pillar of a motor vehicle which contains a functional channel for receiving lines between a rigid support and a panel. The functional channel forms a pre-assembly unit with the lines, is attached to the carrier via a sliding connection and in turn serves to attach the cladding.

From the DE 199 32 800 A1 a carrier arrangement for a vehicle body is known which has a rigid hollow profile which is used to guide a fluid line and to which a panel is fastened by fastening clips. The object of the invention is to provide a carrier part which is further improved in terms of function, production technology and with regard to an even simpler assembly.

The object is achieved by the features of claims 1 and 13. Advantageous and particularly expedient developments of the invention can be found in the subclaims.

According to claim 1, the base body of the carrier part can be fastened to the shell of the column by means of at least one fastening element formed as a separate component.

The fastening element can thus be connected as an exchangeable part to the base body of the carrier part. Depending on the required number and / or geometry, different fastening elements can therefore be provided for different installation situations, with which the base body can be fastened to the inner sheet of the column. The fastening element can be inserted detachably, in particular detachably without tools, into a recess in the base body and / or in the inner panel of the column.

As an alternative or in addition to this, the base body can be connected to an interior trim part via a further fastening element, which is formed as a separate component and which covers the carrier part. Here, too, the separate fastening element can each be inserted into a recess in the base body and / or in the interior trim part.

The base body of the carrier part can therefore be fastened to the inner panel of the column with a first clip connection, for example. At the same time, the head airbag module and the inner lining can be attached to the base body via a second clip connection. In addition to a simpler design of the base body in terms of manufacturing technology, this results in two assembly units that interact functionally.

A carrier part designed in this way can be mounted on the vehicle using the following assembly method: First, the base body can be clipped onto the inner panel of the pillar, for example the A pillar, of the body; then said lines are assembled; then the inner lining with the head airbag module is clipped on as an assembly unit. Should the airbag module have been activated in the event of a crash, the inner lining being torn open in a known manner, a new inner lining with a new airbag module as an assembly unit can be installed in a simple manner during a repair.

The second clip connection can preferably be formed by clips inserted in a form-fitting manner in retaining brackets of the interior lining, which extend through recesses in a retaining plate of the head airbag module and which are clipped into recesses in the base body. The holding plate of the airbag module is thus clamped or reliably held between the holding brackets of the interior lining and the base body in a structurally particularly simple manner.

Furthermore, the base body can be formed by three easy-to-manufacture carrier elements which are arranged on a carrier rail and which each have a fastening clip that interacts with the inner sheet of the column. The fastening clips can be inserted into recesses in the carrier elements or injected directly into them.

To adapt to possibly different vehicle types and / or to To compensate for manufacturing tolerances, the carrier elements can be arranged displaceably on the carrier rail and can carry means for positioning the carrier elements on the column on their support surface facing the inner sheet of the column. In particular, positioning mandrels can be formed on the support surfaces of the support elements, which protrude into corresponding bores in the inner panel of the column.

Furthermore, the recesses for the clips of the second clip connection can be provided in the two outer carrier elements of the base body, whereby a sufficiently stable mounting of the airbag module and the inner lining is achieved with little manufacturing effort.

In addition, retaining tabs, approximately in alignment, for at least one line running on the inner panel of the column can be molded onto the carrier elements. The line can be, for example, a cable harness with electrical leads to the airbag module and possibly other functional parts (interior lighting, sunroof actuation, etc.).

Preferably, the retaining tabs are each formed by two clip-like, resiliently resilient brackets, which ensure a reliable, vibration-eliminating retention of the line.

Furthermore, receptacles can be provided on the support elements opposite the retaining tabs, in which a water drainage line is guided running along the inner sheet of the column.

Finally, in a structurally and technically simple manner, the receptacles can be formed by indentations which are open towards the inner lining and which adjoin a flange section of the inner sheet of the column and, together with this, form the guidance of the water drainage line.
