Description
"Schiebedach fÜr Kraftwagen" Die Erfindung bezieht sich auf Schiebedächer für Kraftwagen. Es ist bekanntg daß bei Kraftwagen mit nach oben offenem Fahrgastraum häufig ein starkes Schwingen des im Innenraum des Fahrzeugs vorhandenen Luftvolumens eintritt, was zu erheblicher Belästigung der Insassen führen kann. Besonders unangenehm können sich derartige Schwingungen, die von der Fahrgeschwindigkeit des Kraftwagens und der Öffnungsweite des Schiebedaches abhängig sind, dann auswirken, wenn sie in Resonanz, d.h. mit der Eigenfrequenz des im Fahrgastraum vorhandenen Luftvolumens erfolgen."Sunroof for motor vehicles" The invention relates to sliding roofs for motor vehicles. It is known that in motor vehicles with an upwardly open passenger compartment often strong fluctuations in the volume of air present in the interior of the vehicle occurs, which can lead to considerable nuisance for the occupants. Particularly uncomfortable Such vibrations can be caused by the driving speed of the vehicle and the opening width of the sunroof are dependent, then have an effect if they in resonance, i.e. with the natural frequency of the air volume in the passenger compartment take place.
Um solche Resonanzschwingungen zu vermeiden, ist es also für den Fahrer eines Kraftwagens erforderlich, die Öffnungsweite des Schiebedaches der jeweiligen Fahrgeschwindigkeit anzupassen. Er muß also bei stark wechselnder Fahrgeschwindigkeit häufig von Hand das Schiebedach bewegen bzw. bei einem durch eine Hilfskraft bewegten Schiebedach die Steuervorrichtung im Öffnungs- oder Schließsinne betätigen oder aber das Selii-ebedach nur so weit öffnen, daß auch bei der höchsten möglichen Fahrgeschwindigkeit keine störendEnSchwingungen der Luft im Fahrgastraum auftreten können. Bei der zuerst angeführten Möglichkeit ist es nachteilig, daß die Konzentrat-ior. des Fahrers ur.-dnstig be24-nflußt werden kann und bei der z",;eitc;n vilirde bei niedrigen Q> scliviindiC.-,'-Zeiteii der Vorteil eines Schiebedaches nicht voll ,::-enutzt werden -'z--j.,cLnen. Mur Verweidun,#, dieser -rach#eile wird deshalb genEß vorlie-Z #i U Co# Gender xirfindun-- ein Schietedach für Kraftw":#igen mit einer von der FahrLeschwindigkeit des Kraftwagens abhEngigen automatischen Bet.Etigung ini Sinne zunehmenden Schließens des offenen Schiebedaches bei zunehmender Fahrgeschviir-digxl-.eit und umgekehrt zunehmender# Öffnens bei abnelu-ender Fahrr-aschwindigkeit vorgeschlagen. Uri bei laufend wecI-#selnder Fahrgesclrjiir.dig'#ieit eino di#.uernde Beviegung cles Sclhiebedaches zu vermeiden. wird weiter vorjeschla,7en, dai.'i das Üffnen und Schließen des ;3c.-L--iebedaches stu--12envie-Ä.se in vor. verscIllieder.en digkeits-*#.',ere--!c-',-en erf olgt. Ilach einei. weiteren vorteilhaften Ausführun-sforn# der ErtD findung ist eine Sperre vorgesehen, die das Schiebedach auch bei der höchsten riö,2#lichen einen Spalt weit offen hält. Schließlich i--t es vort-z;--;lhaft., vienn individuellen Einstellen der öffnungsweite des Schiebedaches die automatische DetL*#»tigunr- absc-haltbar bzw. von Hand übersteuerbar ist. Die Steusrung der automatischen Betätigung kann z.B. elektrisch oder hydraulisch erfolgen2 indem in an sich bek"-nn-'Uer Weise ein elektriScher Generator oder eine Hydraulikpumpe so ' am Pahrzeug angeordnet ist, daß ihre Drehzahl proportional der jeweiligen Fahrgeschwindigkeit ist und die von dem Generator bzw. der Hydraulikpumpe ausgehenden Impulse zur Steuerung herangezogen werden.In order to avoid such resonance vibrations, it is therefore necessary for the driver of a motor vehicle to adapt the opening width of the sliding roof to the respective driving speed. He must therefore often move the sunroof by hand when the driving speed changes significantly, or actuate the control device in the opening or closing direction when the sunroof is moved by an auxiliary force, or only open the sliding roof so far that even at the highest possible driving speed, there are no disruptive vibrations the air in the passenger compartment. In the case of the first option, it is disadvantageous that the concentrate ior. of the driver can be badly influenced and with the z ",;eitc; n vilirde at low Q> scliviindiC .-, '- the advantage of a sunroof not fully, :: - are used -'z-- j., cLnen. Mur Verweidun, #, this -rach # haste will therefore be enjoyed-Z #i U Co # Gender xirfindun-- a sloping roof for motor vehicles with an automatic activation depending on the vehicle speed in the sense of increasing closing of the open sunroof with increasing speed and, conversely, increasing opening with decreasing speed. Uri with constantly changing driving gear. it is further vorjeschla, 7en, dai.'i the opening and closing of the; 3c.-L - iebedach stu - 12envie-Ä.se in vor. verscIllieder.en digkeits - * #.

Finally, it is possible to adjust the opening width of the sunroof individually so that the automatic DetL * # »tigunr-absc-hold or can be overridden by hand. The Steusrung the automatic actuation may, for example electrically or hydraulically erfolgen2 by an electric generator or a hydraulic pump is disposed 'at the Pahrzeug in a bek "-nn-'Uer manner that its rotational speed is proportional to the respective travel speed and or of the generator . the impulses emanating from the hydraulic pump are used for control purposes.
