Abstract
Description
Die Erfindung betrifft einen Sitz, bestehend aus einer Rückenlehne und einer Sitzfläche mit einem Federelement zur Verwendung im Rallyesport.The The invention relates to a seat consisting of a backrest and a seat with a spring element for use in rallying.
Es ist bekannt, dass im Rallyesport Hartschalensitze zum Einsatz kommen, die über kein Federelement verfügen. Große Stoßbelastungen können dadurch nicht aufgenommen werden.It is known that hard-shell seats are used in rallying, the above have no spring element. Size shocks can not be included.
Aus der WO 02/060299 A1 ist ein selbstregulierender Allzweckstuhl bekannt, bei dem die Sitzfläche als eine einseitig eingespannte Blattfeder ausgebildet ist, wobei das freie Ende der Blattfeder in Richtung Rückenlehne weist. Entsprechend einer aufgebrachten Körpermasse einer Person und der Federkonstante stellt sich eine Durchbiegung der Blattfeder ein. Eine so ausgebildete Sitzfläche ist für das Aufnehmen von Stoßbelastungen ungeeignet, da die beim Stoß wirkende Kraft fast ausschließlich über die Wirbelsäule aufgenommen wird, was zu Verletzungen der Wirbelsäule führen kann.Out WO 02/060299 A1 discloses a self-regulating general purpose chair, where the seat is formed as a cantilevered leaf spring, wherein the free end of the leaf spring points in the direction of the backrest. Corresponding an applied body mass a person and the spring constant turns a bend the leaf spring. Such a trained seat is for absorbing shock loads unsuitable, since the impact acting Strength absorbed almost exclusively via the spine which can lead to injuries to the spine.
Aufgabe der Erfindung ist es, einen Sitz, bestehend aus einer Rückenlehne und einer Sitzfläche mit einem Federelement, wobei das Federelement eine Blattfeder ist, zu entwickeln, der für Stoßbelastungen ausgelegt ist.task The invention is a seat consisting of a backrest and a seat with a spring element, wherein the spring element is a leaf spring, to develop for shocks is designed.
Erfindungsgemäß wird die Aufgabe durch einen Sitz gelöst, bestehend aus einer Rückenlehne und einer Sitzfläche mit einem Federelement, wobei das Federelement eine Blattfeder ist, die nacheinander in die Bereiche Federeinspannung, biegeweicher Federbereich und biegesteifer Federbereich aufgeteilt ist und wobei die Blattfeder mit der Federeinspannung auf der Sitzfläche befestigt ist, der sich anschließende biegeweiche Federbereich über eine in der Sitzfläche befindliche Lagerkrümmung abrollbar angeordnet ist und der sich daran anschließende biegesteife Bereich in Richtung der Rückenlehne zeigt. Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.According to the invention Task solved by a seat, consisting of a backrest and a seat with a spring element, wherein the spring element is a leaf spring, the successive in the areas Federeinspannung, bending soft spring range and rigid spring area is divided and where the leaf spring is attached to the seat with the Federeinspannung on itself subsequent pliable feathered area over one in the seat located bearing curvature is arranged unrollable and the subsequent bending resistant Area towards the backrest shows. Embodiments of the invention are shown in the subclaims.
Der Vorteil der Erfindung besteht darin, dass körperschädliche Vertikalbeschleunigungen, hervorgerufen durch hohe Stoßbelastungen, stark vermindert werden, was auch zu erhöhter Fahrsicherheit führt. Stauchungen der Wirbelsäule und Rückenverletzungen werden somit wesentlich gemindert.Of the Advantage of the invention is that body-damaging vertical accelerations, caused by high impact loads, be greatly reduced, which also leads to increased driving safety. compressions The spine and back injuries are thus significantly reduced.
Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles näher erläutert. Die dazugehörige Zeichnung zeigt:following the invention will be explained in more detail with reference to an embodiment. The associated Drawing shows:
