Abstract

The detection is carried out by coding using a special seat belt lock (5) in the vehicle and a snap-in plug integrated in the child seat. Independent claims are included for the following: (1) a length adjustable seat belt; (2) a seat belt lock with integrated magneto-electric detection system for the snap-in plug of the child seat and for coupling to the control electronic of the passenger airbag; (3) child seat with integrated seat belt lock and snap-in plug with integrated trip magnet.

Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft einen Sicherheitsgurtmechanismus auf dem Gebiet des Fahrzeug- sowie des Kindersitzbaus, der den Beifahrerairbag in einem Fahrzeug, bei mitgeführtem Kindersitz auf dem Platz des Beifahrers, vorübergehend außer Funktion setzt.The invention relates to a seat belt mechanism in the field of Vehicle and child seat construction, which the passenger airbag in a vehicle carried child seat on the passenger seat, temporarily inoperative puts.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

In der DE 195 18 410 wird eine Einrichtung zum Erkennen eines Kindersitzes in einem Kraftfahrzeug, zum vorübergehenden Immobilisieren eines Beifahrerairbags beschrieben, wobei der Airbag des Beifahrers mittels eines Transponders, der sowohl in den Kindersitz, als auch in die Rückenlehne des Beifahrersitzes eingebaut wurde, außer Funktion gesetzt wird. Die beschriebene technische Lösung hat den Nachteil, daß das Transpondersignal durch verändern der Position des Kindersitzes (verrutschen infolge Bremsmanöver) gestört werden kann, so das der Beifahrerairbag trotzdem ausgelöst wird. Andererseits könnte die Auslösung des Beifahrerairbags gerade dann verhindert werden, wenn sich der Kindersitz auf dem Rücksitz des Fahrzeuges befindet und die Signalübertragung zwischen dem Transponder im Kindersitz und dem Empfanger in der Rückenlehne des Beifahrersitzes aber aufrecht erhalten wird. Ein Beifahrer wäre dann im Fall eines Unfalls durch den Ausfall des Airbags einer erhöhten Gefahr ausgesetzt.DE 195 18 410 describes a device for recognizing a child seat a motor vehicle for the temporary immobilization of a passenger airbag described, the passenger's airbag using a transponder that both in the child seat, as well as in the backrest of the front passenger seat, is disabled. The technical solution described has the disadvantage that the transponder signal by shifting the position of the child seat (slip due to braking maneuvers), so that the front passenger airbag nevertheless is triggered. On the other hand, the passenger airbag could be deployed just then be prevented if the child seat is in the back seat of the vehicle located and the signal transmission between the transponder in the child seat and the receiver in the backrest of the passenger seat is maintained. A passenger would then be one in the event of an accident due to the failure of the airbag exposed to increased danger.

Wesen der ErfindungEssence of the invention

Die Erfindung dient dem Ziel, die Gefahr zu beseitigen, die von einem sich entfaltenden Airbag im Fall eines Unfalls ausgeht, da dieser infolge des hohen Explosionsdruckes, für ein auf dem Platz des Beifahrers im Kindersitz befindliches Kind, ein hohes zusätzliches Verletzungsrisiko darstellt.The aim of the invention is to eliminate the danger posed by one deploying airbag in the event of an accident, because this is due to the high Explosion pressure, for one in the seat of the passenger in the child seat Child, which represents a high additional risk of injury.

Durch einen längenverstellbaren kombinierten Sicherheitsgurt (1), (2), (3) und (4) (siehe Seite 4 Fig. 2) bestehend aus Gurtschloß (1) und speziellem Raststecker (2), der gleichzeitig als Geber für ein in das Gurtschloß (5) des Beifahrersitzes (9) (siehe Seite 3 Fig. 1) integriertes magnetoelektronisches, auf dem Hallgeberprinzip beruhendem Erkennungssystem (6) dient, wird das Steuergerät (7) welches für das Auslösen des Beifahrerairbags verantwortlich ist, außer Betrieb gesetzt.With a length-adjustable combined seat belt ( 1 ), ( 2 ), ( 3 ) and ( 4 ) (see page 4 Fig. 2) consisting of a belt buckle ( 1 ) and a special latching plug ( 2 ), which also acts as an encoder for a seat belt buckle ( 5 ) of the front passenger seat ( 9 ) (see page 3 Fig. 1) integrated magnetoelectronic, based on the Hall sensor principle detection system ( 6 ), the control unit ( 7 ) which is responsible for triggering the front passenger airbag is put out of operation.

Dieser kombinierte Sicherheitsgurt (1), (2), (3) und (4) (siehe Seite 4 Fig. 2) wird durch den Hersteller unlösbar unter Verwendung von Gurtlaschen (10) (siehe Seite 3 Fig. 1), die ein Durchrutschen des kombinierten Sicherheitsgurtes verhindern, am Kindersitz (8) derart angebracht, das der Sicherheitsgurt des Beifahrers in das Gurtschloß (1) des Kindersitzes (8) eingerastet und der Gurt am Kindersitz (8) mit dem als Signalgeber in Form eines Auslösemagneten (4) ausgebildeten Raststeckers (2) wiederum in das mit dem Hallgeber (6) ausgestatteten Gurtschloß (5) des Beifahrersitzes (9) eingerastet wird. Durch das Integrieren des kombinierten Sicherheitsgurtes (Raststeckergeber, Gurtschloß und verstellbarer Gurt) in den Kindersitz wird gleichzeitig der zweckentfremdete Gebrauch dieses Gurtsystems verhindert. Bedienfehler durch herkömmliches Angurten des Kindersitzes mit dem normalen Gurt des Beifahrers werden dadurch ausgeschlossen, daß am Kindersitz nur noch eine Gurtführungslasche an der Rückenlehne des Kindersitzes benutzt werden kann, da der kombinierte Sicherheitsgurt zusätzlich vom Hersteller durch die zweite Gurtführungslasche eingezogen wird.This combined seat belt ( 1 ), ( 2 ), ( 3 ) and ( 4 ) (see page 4 Fig. 2) is made unsolvable by the manufacturer using belt tabs ( 10 ) (see page 3 Fig. 1) which prevent slipping prevent the combined seat belt from being attached to the child seat ( 8 ) in such a way that the seat belt of the front passenger engages in the buckle ( 1 ) of the child seat ( 8 ) and the belt on the child seat ( 8 ) is designed with a signaling device in the form of a release magnet ( 4 ) The locking plug ( 2 ) is in turn engaged in the belt buckle ( 5 ) of the front passenger seat ( 9 ) equipped with the Hall sender ( 6 ). By integrating the combined seat belt (snap connector, belt buckle and adjustable belt) into the child seat, the misuse of this belt system is also prevented. Operating errors due to conventional belting of the child seat with the normal belt of the front passenger are excluded by the fact that only one belt guide strap on the backrest of the child seat can be used on the child seat, since the combined seat belt is also retracted by the manufacturer through the second belt guide strap.

Der Vorteil dieser Lösung ist der sowohl mechanisch als auch elektronisch einfache Systemaufbau, der komplett im Fahrzeug verbleibt und nicht durch den Kindersitzhersteller realisiert werden muß. Außerdem eignet sich diese Erfindung auch zum Nachrüsten schon vorhandener Kindersitze und Airbagsysteme durch den Fahrzeug- bzw. Kindersitzhersteller. Dabei ist der Kostenaufwand für den Kindersitz sehr gering (Standardgurtschloß mit leicht modifiziertem Raststecker).The advantage of this solution is that it is both mechanically and electronically simple System structure that remains completely in the vehicle and not through the Child seat manufacturer must be realized. This invention is also useful also for retrofitting existing child seats and airbag systems with the Vehicle or child seat manufacturer. Here is the cost of the child seat very low (standard belt buckle with slightly modified snap-in connector).

Die Betriebssicherheit der Airbagauslösung bei normalem Angurten bzw. auch nicht Angurten bleibt erhalten. Der Kindersitz kann auch auf dem Rücksitz angegurtet werden ohne die Airbagauslösung für einen Beifahrer zu gefährden.The operational safety of the airbag deployment with normal belting or not Belting is retained. The child seat can also be strapped in the back seat are without endangering the airbag for a passenger.

Die Systemstabilität der Erfindung wird durch eine umgebungsunabhängige Signalübertragung des magnetoelektronischen Systems gewährleistet.The system stability of the invention is due to an environment independent Signal transmission of the magnetoelectronic system guaranteed.
