Abstract

The invention relates to a belt for reducing the impact of a fall. Said belt is used for reducing the catching forces in a fall. The belt consists of a belt band (10) which is interlaced in an area (14, 15) which extends from the ends (12, 13) of the belt. The belt band (10) is provided with means (24) which can be connected to the catching belt and means (20, 21) at each end which can be fixed at a stopping point or at a connecting means in such a way that the interlaced area is unravelled in a fall. The belt band (10) is interlaced in such a way that it forms a ring (16), whereby the areas (14, 15) extending from the ends (12, 13) overlap on parts of the ring circumference. Said areas (14, 15) are connected within the overlapping (18) due to the interlacing.

Description

Band-Falldämpfer Band shock absorber
Beschreibungdescription
Die Erfindung betrifft einen Band-Falldämpfer zur Reduzierung der Auffangkräfte bei einem Absturz einer Person von einer Leiter, einem Steigweg, einem Podest oder dergleichen. Der Falldämpfer weist ein Gurtband auf, das in einem von seinen Enden ausgehenden Bereich durch Ineinanderweben verbunden ist und das am ersten Ende des Falldämpfers Mittel, z.B. einen Karabinerhaken, zum Verbinden mit einem Auffang- gurt und am zweiten Ende des Falldämpfers Mittel, z.B. Ösen, zum Befestigen an einem Anschlagpunkt oder einem Verbindungsmittel aufweist. Bei einem Absturz wird der ineinan- dergewebte Bereich aufgerissen, wodurch die Auffangkräfte des Absturzes reduziert werden.The invention relates to a band energy absorber to reduce the fall forces in the event of a person falling from a ladder, a climbing path, a platform or the like. The shock absorber has a belt webbing which is connected by interweaving in an area starting from its ends and which has means at the first end of the shock absorber, e.g. a snap hook, for connection to a harness and means at the second end of the fall damper, e.g. Has eyelets, for attachment to a lifting point or a connecting means. In the event of a fall, the interwoven area is torn open, reducing the fall arrest forces.
Ein solcher Band-Falldämpfer ist aus DE-U-295 02 632 bekannt. Beim Besteigen eines Gittermasten muß der Anschlagpunkt entsprechend dem Höhengewinn ständig neu gewählt werden. Bei jedem Wechsel des Anschlagpunktes, d.h. wenn das zweite Ende des Falldämpfers an einem höher gelegenen Punkt angeschlagen wird, ist die Person kurzzeitig ungesichert.Such a band energy absorber is known from DE-U-295 02 632. When climbing a lattice mast, the anchor point must be constantly re-selected according to the height gain. Every time the anchor point changes, i.e. if the second end of the fall arrester is struck at a higher point, the person is temporarily unsecured.
Der Erfindung liegt die Aufgabe zugrunde, eine lückenlose Sicherung einer Person auf einem Steigweg zu ermöglichen, bei dem der Anschlagpunkt fortschreitend neu gesetzt werden muß.The invention has for its object to enable a complete backup of a person on a climb, in which the anchor point must be progressively reset.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Gurt durch die Ineinanderwebung zu einem Ring genäht ist, wobei die sich die von den Enden ausgehenden Bereiche auf einem Teil des Ringumfangs überlappen und sie innerhalb dieser Überlappung durch die Ineinanderwebung verbunden sind, daß das Mittel zum Verbinden mit einem Auffanggurt innerhalb des Teils des Ringes angeordnet ist, der zwischen den Enden des Überlappungsbereichs liegt und in dem selbst keine Überlappung besteht, und - daß an jedem Ende des Gurtes ein Mittel zum Befestigen an einem Anschlagpunkt oder einem Verbindungsmittel vorgesehen ist.According to the invention, this object is achieved in that the belt is sewn into a ring through the interweaving, the regions starting from the ends overlapping on part of the ring circumference and being connected within this overlap by the interweaving, that the means for connecting to a harness is located within the portion of the ring which is between the ends of the overlap area and in which there is no overlap itself, and - that means are provided at each end of the belt for attachment to an anchor point or a connecting means is.
Dadurch, daß zwei Verbindungsmittel vorhanden sind, kann sich der Benutzer abwechselnd mit dem einen und dem anderen Verbindungsmittel anschlagen, so daß er jederzeit gesichert ist .The fact that there are two connecting means allows the user to strike alternately with one and the other connecting means, so that he is secured at all times.
Vorzugsweise sind die von den Enden ausgehenden Bereiche des Gurtes auf mehr als dem halben Umfang des Ringes miteinander durch Ineinanderweben verbunden.The regions of the belt extending from the ends are preferably connected to one another by interweaving on more than half the circumference of the ring.
Vorzugsweise erstreckt sich der zwischen den beiden Enden liegende Überlappungsbereich über etwa 2/3 des Umfanges des Ringes.The overlap region lying between the two ends preferably extends over approximately 2/3 of the circumference of the ring.
Vorzugsweise besteht das Gurtband aus zwei Stücken, die an der Stelle, an der sich das Mittel zum Verbinden mit einem Auffanggurt befindet, durch eine Naht verbunden sind. Vor- zugsweise überlappen sich die beiden Stücke im Bereich des Mittels zum Verbinden mit einem Auffanggurt und sind sie zu beiden Seiten dieses Mittels miteinander vernäht.The belt strap preferably consists of two pieces which are connected by a seam at the point at which the means for connecting to a safety belt is located. The two pieces preferably overlap in the area of the means for connecting to a safety harness and are sewn together on both sides of this means.
Vorzugsweise ist der zu dem Ring genähte Gurt so gefaltet und in einer Schlauchhülle verpackt, daß an einem Ende derPreferably, the belt sewn to the ring is folded and packaged in a tubular sleeve that at one end of the

The method of weaving a webbing into one another, which tears apart in the event of a fall with a defined force, is known and is therefore not described in more detail here.

Fig. 5 und 6 das Zusammenfalten des Band-Falldämpfers nach Fig.4.5 and 6 the folding of the band-type shock absorber according to Fig. 4.
Gemäß Fig. 1 weist der Band-Falldämpfer ein Gurtband 10 mit zwei Enden 12, 13 auf. Die von den Enden 12, 13 ausgehenden Bereiche 14, 15 des Gurtbandes 10 sind so übereinanderge- legt, daß sich ein Ring 16 ergibt. Die Bereiche 14, 15 über- läppen sich etwa auf 2/3 des Umfangs des Ringes 16. Innerhalb des Überlappungsbereichs 18 sind die beiden Bereiche durch Ineinanderweben 19 miteinander verbunden. Die Ineinanderwebung 19 ist in der Zeichnung durch eine Zickzacklinie angedeutet .1, the belt fall damper has a belt strap 10 with two ends 12, 13. The areas 14, 15 of the webbing 10 starting from the ends 12, 13 are superimposed in such a way that a ring 16 is obtained. The regions 14, 15 overlap approximately on 2/3 of the circumference of the ring 16. Within the overlap region 18, the two regions are connected to one another by interweaving 19. The interweaving 19 is indicated in the drawing by a zigzag line.
Beim Ineinanderweben werden kurze Faserbündel des einen Bereichs 14 in den anderen Bereich 15 und umgekehrt eingewebt. Durch die Länge der eingewebten Faserbündel läßt sich die Kraft steuern, die zum Herausziehen der Faserbündel und damit zum Auseinanderreißen der Bereiche 14, 15 notwendig ist. Innerhalb des Überlappungsbereichs 18 ist der Ring 16 einmal um 180° tordiert, so daß beide Enden 12, 13 auf der Außenseite des Ringes 16 liegen. Als Mittel zum Befestigen an einem Anschlagpunkt oder einem Verbindungsmittel sind an beiden Enden 12, 13 Laschen oder Ösen 20, 21 genäht. In dem Bereich 22 des Ringes 16, in dem der Ring 16 nur aus einer Lage des Gurtbandes 10 besteht, ist ein Karabinerhaken 24 angeordnet, wobei das Gurtband 10 durch dessen Verbindungsöse 26 gezogen ist. Der Karabinerhaken 24 dient als Mittel zum Verbinden mit einem Auffanggurt. Das Gurtband 10 hat eine Breite von etwa 50 mm und muß seitlich zusammengedrückt durch die Ringöse mit 25 mm Durchmesser des Karabinerhakens 24 gezogen werden. Der Karabinerhaken 24 ist dadurch innerhalb des von der Ineinanderwebung freien Bereiches 22 fest- gelegt und nicht verschiebbar.When weaving one into the other, short fiber bundles from one region 14 are woven into the other region 15 and vice versa. The length of the woven-in fiber bundle can be used to control the force required to pull the fiber bundle out and thus tear apart the regions 14, 15. Within the overlap area 18, the ring 16 is twisted once through 180 °, so that both ends 12, 13 lie on the outside of the ring 16. 12, 13 tabs or eyelets 20, 21 are sewn at both ends as means for fastening to an attachment point or a connecting means. In the area 22 of the ring 16, in which the ring 16 consists only of one layer of the webbing 10, a snap hook 24 is arranged, the webbing 10 being pulled through its connecting eye 26. The snap hook 24 serves as a means of connecting to a harness. The webbing 10 has a width of about 50 mm and must be pulled laterally compressed through the eyelet with a 25 mm diameter of the snap hook 24. The snap hook 24 is thereby fixed within the area 22 which is free of interweaving and cannot be moved.
Der Ring 16 wird, wie in Fig. 2 und 3 gezeigt, zu einem länglichen geraden Element gefaltet. Dazu wird der Ring 16 zunächst diametral gerade gezogen, so daß sich die Öse 20 am einen Ende befindet. Man hat dann drei Abschnitte, nämlich den in Fig. 2 linken Abschnitt 31 zwischen der einen Öse 20 und dem Karabinerhaken 24, wobei sich hier der Karabinerhaken 24 in der Mitte des von der Ineinanderwebung freien Bereiches 22 befindet, den mittleren Abschnitt 32 zwischen dem Karabinerhaken 24 und der anderen Öse 21 und den rechten Abschnitt 33 der sich über die Öse 21 hinaus erstreckt. Der rechte Abschnitt 33 wird auf den mittleren Abschnitt 32 gefaltet (Pfeil I) , so daß sich die Öse 21 auf der Außenseite befindet und der linke Abschnitt 31 wird dann auf den mittleren Abschnitt gelegt (Pfeil II) . Der rechte Abschnitt 33 liegt dann zwischen dem mittleren Abschnitt 32 und dem linken Abschnitt 33. Bei dem so gefalteten Gurtband 10 liegt am einen Ende der Karabinerhaken 24 und befinden sich am anderen Ende die beiden Ösen 20, 21. So zusammengefaltet wird der Ring 16 in eine Schlauchhülle 36 geschoben (Fig. 3) oder durch Bändchen zusammengehalten. Damit ist der Bandfalldämpfer fertig. Für die Verwendung des Bandfalldämpfers wird der Karabinerhaken 24 an der vorderen oder hinteren Fangöse eines Standard-Auffanggurtes der zu sichernden Person befestigt . Mittels Karabinerhaken werden an den Ösen 20, 21 jeweils Verbindungsmittel 26, 27 angehängt, an deren freien Enden sich ebenfalls Karabinerhaken 28, 29 befinden, mit denen sich der Benutzer abwechseln anschlagen kann. Klettert der Benutzer auf einen Gittermast, so sichert er sich durch abwechselndes Anschlagen der beiden Verbindungsmittel 26, 27 mittels der Karabinerhaken 28, 29, so daß er zu jedem Zeitpunkt gegen einen Absturz gesichert ist.The ring 16, as shown in Figs. 2 and 3, is folded into an elongated straight element. For this purpose, the ring 16 is first drawn straight, so that the eyelet 20 is at one end. There are then three sections, namely the section 31 on the left in FIG. 2 between the one eyelet 20 and the snap hook 24, here the snap hook 24 being located in the middle of the area 22 free from interweaving, the middle section 32 between the snap hook 24 and the other eyelet 21 and the right section 33 which extends beyond the eyelet 21. The right section 33 is folded onto the middle section 32 (arrow I) so that the eyelet 21 is on the outside and the left section 31 is then placed on the middle section (arrow II). The right section 33 then lies between the middle section 32 and the left section 33. In the webbing 10 folded in this way, the snap hooks 24 lie at one end and the two eyelets 20, 21 are located at the other end a tubular sleeve 36 pushed (Fig. 3) or held together by tapes. The belt shock absorber is now finished. To use the fall arrester, the snap hook 24 is attached to the front or rear safety eye of a standard safety harness of the person to be secured. By means of carabiner hooks 26, 27 are attached to the eyelets 20, 21, at the free ends of which there are also carabiner hooks 28, 29 with which the user can alternately strike. If the user climbs on a lattice mast, he secures himself by alternately striking the two connecting means 26, 27 by means of the snap hooks 28, 29, so that he is secured against falling at any time.
Verliert der Benutzer den Halt und fällt in den Band-Falldämpfer, so wirkt der Fangstoß auf die Ineinanderwebung 19 des Gurtbandes 10 und reißt diese von dem Ende her auf, an dem sich die betreffende Öse 20, 21 befindet, mit der das Verbindungsmittel 26, 27 verbunden ist, das in diesem Moment gerade angeschlagen ist. Der Band-Falldämpfer wird aus der Schlauchhülle 36 herausgezogen und je nach der Stärke des Fangstoßes wird die Ineinanderwebung 19 ein größeres oder kleineres Stück weit auseinandergerissen. Durch das Auseinanderreißen der Ineinanderwebung 19 wird Fallenergie absorbiert und die maximale auf den Benutzer einwirkende Kraft verringert .If the user loses his grip and falls into the strap energy absorber, the impact impact acts on the interweaving 19 of the belt strap 10 and tears it open from the end at which the eyelet 20, 21 in question, with which the connecting means 26, 27 is connected, which is just struck at this moment. The band energy absorber is pulled out of the hose cover 36 and, depending on the strength of the impact force, the interweaving 19 is torn apart a larger or smaller piece. By tearing apart the weave 19, fall energy is absorbed and the maximum force acting on the user is reduced.
Ein besonderer Vorteil des erfindungsgemäßen Band-Falldämpfers ist, daß er auch dann einen Fall noch ausreichend dämpft, wenn er falsch eingesetzt wird, indem der Benutzer die Fangöse des Auffanggurtes nicht an dem Karabinerhaken 24, der sich innerhalb des einfachen Bereichs des Ringes 16 befindet, sondern an einem der beiden Karabinerhaken 28, 29 der Verbindungsmittel 26, 27 einhängt und nur den anderen Karabinerhaken 29 bzw. 28 zur Sicherung verwendet. Fällt der Benutzer so gesichert in den Falldämpfer, so wird die Inein- anderwebung 19 ebenfalls aufgerissen und der Fall abgebremst . Das in Fig. 4 gezeigte Ausführungsbeispiel des Band-Falldämpfers unterscheidet sich von dem nach Fig. 1 dadurch, daß das Gurtband 10 aus zwei Stücken besteht, die im Bereich des Karabinerhakens 24 zusammengenäht sind. Die beiden Stücke überlappen sich an dieser Stelle und sind links und rechts von dem Karabinerhaken 24 mit einer Naht 40 verbunden. Diese beiden Nähte 40 sind außerdem noch unter Bildung einer Schlaufe 42 miteinander vernäht, so daß der Karabinerhaken 24 an dem Gurtband 10 fixiert ist.A particular advantage of the band fall damper according to the invention is that it also sufficiently damps a case if it is used incorrectly by the user not attaching the safety eye of the safety harness to the snap hook 24, which is located within the simple area of the ring 16, but hooks onto one of the two snap hooks 28, 29 of the connecting means 26, 27 and only uses the other snap hooks 29 and 28 for securing. If the user falls into the fall damper in such a secure manner, the interweaving 19 is also torn open and the case is slowed down. 4 differs from that of FIG. 1 in that the webbing 10 consists of two pieces which are sewn together in the region of the snap hook 24. The two pieces overlap at this point and are connected to the left and right of the snap hook 24 with a seam 40. These two seams 40 are also sewn together to form a loop 42, so that the snap hook 24 is fixed to the webbing 10.
Das Gurtband 10 ist bei diesem Ausführungsbeispiel außerdem nicht tordiert und die ein Öse 20 befindet sich deshalb innerhalb des Ringes 16 und die andere Öse 21 außerhalb des Ringes 16. An die Ösen 20, 21 schließt sich jeweils ein kurzes Stück des Gurtbandes 10 ohne Ineinanderwebung an.The webbing 10 is also not twisted in this embodiment and the one eyelet 20 is therefore inside the ring 16 and the other eyelet 21 outside the ring 16. Each of the eyelets 20, 21 is followed by a short piece of the webbing 10 without interweaving .
Zum Zusammenfalten wird die sich innerhalb des Ringes 16 befindende Öse 20 über das Gurtband 10 nach außen gelegt und werden beide Ösen 20, 21 so gerichtet, daß sie von dem Karabinerhaken 24 weg zeigen (Fig. 5) .For folding, the eyelet 20 located within the ring 16 is placed outwards over the webbing 10 and both eyelets 20, 21 are directed so that they point away from the snap hook 24 (FIG. 5).
Die von dem Karabinerhaken 24 abgewandte Hälfte des Ringes 16 wird dann in Richtung des Pfeiles III verlagert, so daß sie in der gleichen Richtung gekrümmt ist wie die Hälfte des Ringes 16 mit dem Karabinerhaken 24. Die von der Innenseite des Ringes 16 abhängende Öse 20 wird nun auf der von dem gefalteten Ring 16 abgewandten, äußeren Seite parallel zu der anderen Öse 21 gelegt (Fig. 6) . Das so gefaltete Gurtband 10 wird seitlich zusammengedrückt und in die Schlauch- hülle 36 geschoben. Am eine Ende der Schlauchhülle 36 schaut dabei wieder der Karabinerhaken 24 und am anderen Ende die beiden Ösen 20, 21 heraus.The half of the ring 16 facing away from the snap hook 24 is then displaced in the direction of the arrow III, so that it is curved in the same direction as half of the ring 16 with the snap hook 24. The eyelet 20 depending on the inside of the ring 16 becomes now placed parallel to the other eyelet 21 on the outer side facing away from the folded ring 16 (FIG. 6). The webbing 10 folded in this way is compressed laterally and pushed into the tubular sleeve 36. The snap hook 24 looks out again at one end of the tubular casing 36 and the two eyelets 20, 21 at the other end.
Bei dieser Ausführungsform ist die Dämpfungscharakteristik weitgehend unabhängig davon, welche der beiden Ösen 20, 21 gerade zum Anschlagen verwendet wurde . Auch bei einer falschen Verwendung des Falldämpfers, wenn sich der Benutzer mit seinem Auffanggurt also an einer der Ösen 20, 21 festmacht, ist die Dämpfungscharakteristik sehr gut. In this embodiment, the damping characteristic is largely independent of which of the two eyelets 20, 21 was just used for striking. Even if the shock absorber is used incorrectly, if the user with its safety harness attached to one of the eyelets 20, 21, the damping characteristics are very good.
