Description
Die Erfindung betrifft eine Schutzvorrichtung für ein Kraftfahrzeug mit einer als Hohlprofil ausgebildeten Rollowelle sowie mit einem flexiblen Flächengebilde, das an der Rollowelle fixiert ist. Die Erfindung betrifft zudem eine Rollowelle für eine derartige Schutzvorrichtung.The invention relates to a protective device for a motor vehicle having a hollow shaft designed as a hollow shaft and with a flexible sheet, which is fixed to the roller blind shaft. The invention also relates to a roller blind shaft for such a protective device.
Eine derartige Schutzvorrichtung ist aus der
Aufgabe der Erfindung ist es, eine Schutzvorrichtung und eine Rollowelle der eingangs genannten Art zu schaffen, die eine einfache und sichere Fixierung des Flächengebildes an der Rollowelle ermöglichen. The object of the invention is to provide a protective device and a roller blind shaft of the type mentioned, which allow a simple and secure fixation of the fabric to the roller blind shaft.
Diese Aufgabe wird dadurch gelöst, dass das Flächengebilde stirnseitig einen T-förmig umgefalzten Stirnrand aufweist, der formschlüssig in einer korrespondierenden, längs der Rollowelle verlaufenden Aussparung der Rollowelle aufgenommen ist. Das Flächengebilde gemäß der Erfindung verzichtet auf Einschnitte im Stirnendbereich und schafft vielmehr eine T-förmige Umfalzung des Stirnrands. Kerbwirkungen am Stirnendbereich des Flächengebildes, die beim Stand der Technik aufgrund der Einschnitte auftreten können, werden bei dem Flächengebilde gemäß der Erfindung vermieden. Der T-förmig umgefalzte Stirnrand erstreckt sich über eine gesamte Breite des Flächengebildes und ist einstückiger Teilbereich des Flächengebildes. Entsprechend komplementär hierzu weist die Rollowelle lediglich eine einzelne, über die gesamte Länge der Rollowelle durchgängig erstreckte Aussparung auf, in der der T-förmig umgefalzte Stirnrand des Flächengebildes formschlüssig aufgenommen ist. Die Aussparung umfasst vorzugsweise einen geradlinig und durchgängig über die Länge der Rollowelle erstreckten Längsschlitz. This object is achieved in that the sheet has frontally a T-shaped folded end edge, which is positively received in a corresponding, extending along the roller blind recess of the roller shaft. The fabric according to the invention dispenses with cuts in the front end region and rather creates a T-shaped Umfalzung the front edge. Notch effects on the front end region of the fabric, which can occur in the prior art due to the incisions, are avoided in the fabric according to the invention. The T-shaped folded end edge extends over an entire width of the sheet and is integral part of the sheet. Correspondingly complementary thereto, the roller shaft only a single, over the entire length of the roller shaft continuously extending recess in which the T-shaped folded end edge of the sheet is positively received. The recess preferably comprises a straight slot which extends in a straight line and continuously over the length of the roller shaft.
In Ausgestaltung der Erfindung umfasst die Aussparung einen zur Innenseite der Rollowelle geschlossenen Hohlraum. Der Hohlraum weist eine in Umfangsrichtung gesehene Breitenerstreckung auf, die um ein Vielfaches größer ist als eine radial gesehene Höhenerstreckung des Hohlraums. In an embodiment of the invention, the recess comprises a closed to the inside of the roller blind cavity. The cavity has a circumferential width seen in the circumferential direction, which is greater by a multiple than a radially viewed height extent of the cavity.
In weiterer Ausgestaltung der Erfindung ist eine Innenwandung des Hohlraums radial zu einem Außenmantel der Rollowelle hin gewölbt. Die Innenwandung des Hohlraums ist – im Querschnitt gesehen – konkav von einer Mittellängsachse der Rollowelle weg nach außen gewölbt. Hierdurch verbleibt radial innerhalb der Innenwandung zur Mitte der Rollowelle hin ein relativ großer freier Innenraum, der von einer als Wickelfeder dienenden Torsionsfeder ausgefüllt werden kann. Ein entsprechender Bauraum innerhalb der Rollowelle wird durch den flachgehaltenen Hohlraum für die Aufnahme des T-förmig umgefalzten Stirnrands des Flächengebildes daher nur unwesentlich beeinträchtigt. In a further embodiment of the invention, an inner wall of the cavity is arched radially to an outer shell of the roller shaft. The inner wall of the cavity is - seen in cross section - concavely curved away from a central longitudinal axis of the roller shaft to the outside. This leaves radially inside the inner wall towards the center of the roller blind shaft towards a relatively large free space, which can be filled by a torsion spring serving as a clock spring. A corresponding space within the roller blind shaft is therefore only slightly affected by the shallow cavity for receiving the T-shaped folded end edge of the fabric.
In vorteilhafter Weise ist die Innenwandung im Wesentlichen koaxial zu einer Mittellängsachse der Rollowelle konkav gewölbt. Da auch eine entsprechende, vorzugsweise als Schraubenfeder ausgebildete Torsionsfeder koaxial zu einer Mittellängsachse der Rollowelle innerhalb der Rollowelle angeordnet ist, ist mit einer solchen Ausführungsform eine besonders gute Ausnutzbarkeit des verbleibenden Bauraums innerhalb der Rollowelle erzielbar. Advantageously, the inner wall is curved substantially concave coaxially to a central longitudinal axis of the roller shaft. Since a corresponding, preferably designed as a helical spring torsion spring is arranged coaxially to a central longitudinal axis of the roller shaft within the roller blind, a particularly good exploitation of the remaining space within the roller shaft is achieved with such an embodiment.
In weiterer Ausgestaltung der Erfindung ist die Rollowelle einteilig aus einem rollierten Metallblech hergestellt. Dies ist eine besonders einfache, kostengünstige und dennoch funktionssichere Ausgestaltung. In a further embodiment of the invention, the roller blind is made in one piece from a rolled sheet metal. This is a particularly simple, inexpensive and yet reliable design.
In weiterer Ausgestaltung der Erfindung ist die Rollowelle als Metallstrangpresshohlprofil gestaltet. Das Metallstrangpresshohlprofil kann als Endlosprofil mittels eines Strangpressverfahrens und eines entsprechenden Extruders hergestellt werden. Zur Erzielung entsprechender Rollowellen wird das Metallstrangpresshohlprofil in einfacher Weise entsprechend abgelängt. In a further embodiment of the invention, the roller shaft is designed as a metal extruded hollow profile. The metal extruded hollow profile can be produced as an endless profile by means of an extrusion process and a corresponding extruder. To achieve appropriate roller blinds the metal extruded hollow profile is cut to length in a simple manner.
In weiterer Ausgestaltung der Erfindung ist der T-förmig umgefalzte Stirnrand durch eine 90°-Umfalzung sowie durch eine zu der 90°-Umfalzung parallel beabstandete 180°-Umfalzung gebildet. In vorteilhafter Weise ist eine Fixierung für wenigstens eine der beiden Umfalzungen vorgesehen. Als Fixierung kann eine linien- oder punktförmige Verschweißung oder auch eine entsprechende Vernähung vorgesehen sein. Der T-förmig umgefalzte Stirnrand ist hierdurch fixiert.In a further embodiment of the invention, the T-shaped folded end edge is formed by a 90 ° Ummung and by a parallel to the 90 ° Ummalzung 180 ° Ummalzung. In Advantageously, a fixation is provided for at least one of the two Umfalzungen. As a fixation can be provided a line or punctiform weld or a corresponding stitching. The T-shaped folded end edge is thereby fixed.
Die erfindungsgemäße Rollowelle ist als Hohlprofil gestaltet und durch Umformung, insbesondere durch Rollierung, hergestellt. Die Umformung umfasst sowohl Kalt- als auch Warmumformungen eines entsprechenden Metallblechs. Die Rollowelle bildet demzufolge eine einteilige Metallblechkonstruktion, die vorzugsweise durch Rollieren geschaffen ist. The roller blind shaft according to the invention is designed as a hollow profile and produced by deformation, in particular by rolling. The forming includes both cold and hot forming a corresponding metal sheet. The roller blind thus forms a one-piece sheet metal construction, which is preferably created by rolling.
Falls die Rollowelle aus einem Metallblech durch Rollieren hergestellt ist, sind aneinander liegende Profilabschnitte des Hohlprofils der Rollowelle durch Punktschweißung gegeneinander fixiert. Die Punktschweißung erfolgt vorzugsweise durch zueinander beabstandete Laserschweißpunkte, die demzufolge gesteppt vorgesehen sind. If the roller shaft is made of a metal sheet by rolling, adjacent profile sections of the hollow profile of the roller blind shaft are fixed by spot welding against each other. The spot welding is preferably carried out by mutually spaced laser welding points, which are therefore provided quilted.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen sowie aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung, das anhand der Zeichnungen dargestellt ist. Further advantages and features of the invention will become apparent from the claims and from the following description of a preferred embodiment of the invention, which is illustrated by the drawings.
