Abstract
Dichtung zwischen einer Fahrzeugaußenverkleidung (3, 5) oder einem Träger (2) für eine Fahrzeugaußenverkleidung (3, 5) und einer Fronthaube (1), mittels welcher der Spalt zwischen Fronthaube (1) und Fahrzeugaußenverkleidung (3, 5) für Flüssigkeiten und Windkräfte verschlossen wird, wenn die Fronthaube geschlossen ist, wobei die Fronthaube aufgrund einer auf die Fronthaube einwirkenden Druckkraft in der Höhe verstellbar ist, gekennzeichnet dadurch, dass die Dichtung (4) als Folge der Einwirkung der Druckkraft derart unter Vergrößerung ihres Volumens verformbar ist, dass die Fronthaube (1) angehoben wird.poetry between a vehicle outer fairing (3, 5) or a carrier (2) for a vehicle exterior trim (3, 5) and a front hood (1), by means of which the gap between Front hood (1) and vehicle outer paneling (3, 5) for liquids and wind forces is closed when the front hood is closed, the Front hood due to a compressive force acting on the front hood in height is adjustable, characterized in that the seal (4) as Consequence of the action of the pressure force under magnification of their Volume is deformable, that the front cover (1) is raised.
Description
Die Erfindung betrifft eine multifunktionale Dichtung insbesondere für den Frontbereich eines Fahrzeugs. Zwischen Motorhaube und Frontendträger wird eine Dichtung gegen den Fahrtwind, eine sogenannte cw-Dichtung, angeordnet, welche in ihrem Volumen derart veränderbar ist, dass sie zur Aufstellung der Motorhaube verwendet werden kann.The The invention relates to a multifunctional seal, in particular for the front area of a vehicle. Between bonnet and front end carrier is a seal against the wind, a so-called cw-seal, arranged, which is variable in their volume so that they are for installation the bonnet can be used.

Somit ist es Aufgabe der Erfindung, in ein vorhandenes Bauelement, in diesem Fall in eine Dichtung, eine Betätigungsvorrichtung zum Anheben einer Motorhaube oder Frontklappe zu integrieren.Consequently It is an object of the invention, in an existing device, in this case in a seal, an actuator for lifting a To integrate bonnet or front door.
Die Dichtung ist derart gestaltet, dass sie sich unter Druckbeaufschlagung so verformt, dass durch deren Verformung die Frontklappe oder Haube angehoben wird.The Seal is designed so that they are pressurized deformed so that lifted by the deformation of the front flap or hood becomes.
Es ist eine weitere Aufgabe der Erfindung, den bei der Haubenaufstellung entstehenden Spalt weitestgehend auszufüllen. Somit füllt die Dichtung durch die Verformung den Spalt aus, wodurch die Kopfbelastung deutlich vermindert wird, insbesondere die Kinderkopfbelastung.It is another object of the invention, in the hood installation to be completed as far as possible. Thus fills the Seal by deforming the gap, reducing the head load is significantly reduced, especially the child's head load.
Es
ist eine weitere Aufgabe der Erfindung, eine Verringerung der Hubbewegung
des hinteren Teils der Frontklappe oder Motorhaube zu erzielen, um
eine z.B. in
Dadurch, dass die Hubbewegung über die verformbare Dichtung ausgeführt wird, wird die Hubbewegung des hinteren Teils der Frontklappe oder Motorhaube bereits durch die Dichtung eingebettet, wodurch ein zusätzlicher Aktuator, wie ein Airbag, obsolet wird, und statt dessen reversible Hebemechanismen zum Einsatz kommen können.Thereby, that the lifting movement over executed the deformable seal is, the lifting movement of the rear part of the front door or hood already embedded by the seal, creating an additional Actuator, like an airbag, becomes obsolete, and instead reversible Lifting mechanisms can be used.
