Description

Technical field of the invention

The Invention belongs to the field of automotive engineering. It is about a device for detecting Kfz.-doors in any position between minimum and maximum opening.

State of the art this area

Car doors are from the motor vehicle manufacturers as standard a door arrester ("Tether") equipped, the only two latching positions, in an intermediate position and in an end position, owns. The vehicle door is characterized in a first opening area with an undefined opening force to open, until the first latching position is reached. Will by renewed or increased use of force overcome this first detent position, can the door further open become; their opening way is limited and terminated by the second detent position.

Shortcomings of the technique on this area

Shortcomings of standard door retainers are, that on the one hand the first detent position can be unintentionally overcome, which in parking situations u. U. damage to the adjacent car. leads, and that on the other hand if the first stop position is not reached, the motor vehicle door returns can accidentally fall, what u. U. to injuries of the descending Vehicle occupants leads. At the same time leads the Fact that the Door with a force is opened, which is not exactly defined, to the door, the second detent position Overuse with too much force can, causing damage at the A-pillar and at the attachment point of the tether on the door. can lead. A fourth shortcoming finally is that at Parking the vehicle on a slope (with the opening open the door the hangseitse) the door not sure enough latches to the door even against the slope to keep pulling power, which is also an unintentional Closing the door with a corresponding risk of injury.

Representation of the technical problem

• – Rastungspositionen nur an vorgegebenen Stellen festlegt und keine stufenlose Arretierung ermöglicht
• – dem Benutzer keine genaue definierte Kraft bei der Öffnung der Tür abverlangt
• – dem Benutzer kein Feedback über die Relation von eingesetzter Kraft und erreichter Türposition gibt
• – bei Erreichen der Endposition bei der Öffnung der Tür durch die konstruktive Auslegung der Endarretierung die Tür eine zusätzliche Beschleunigungskraft erfährt, welche unmittelbar danach durch den Endanschlag wieder aufgefangen werden muß, was wiederum zu Beschädigungen an den Anlenkpunkten führen kann.

The shortcomings of the technology in the standard door locks resulting from the technical design, the

• - Sets detent positions only at predetermined locations and no continuous lock allows
• - Required the user no precise defined force in the opening of the door
• - gives the user no feedback about the relation of inserted force and reached door position
• - Upon reaching the end position in the opening of the door through the structural design of the Endarretierung the door experiences an additional acceleration force, which must be recovered immediately thereafter by the end stop again, which in turn can lead to damage to the articulation points.

• – eine stufenlose Feststellung der Tür auf ihrem Öffnungsweg auf einer frei wählbaren Position nicht möglich ist
• – eine Einstellung der Öffnungskraft nach grundsätzlichen konstruktiven Parametern und nach individuellen Benutzerbedürfnissen nicht möglich ist
• – ein wirkungsvolle Endlagendämpfung nicht vorhanden ist.

The technical problem is thus obviously that

• - A stepless determination of the door on its opening path on a freely selectable position is not possible
• - An adjustment of the opening force according to basic design parameters and individual user needs is not possible
• - An effective cushioning is not available.

Means of solving the technical problem

• – eine sichere, in jeder Position wählbare Türfeststellung ermöglicht
• – durch die konstruktive Auslegung des Schiebers die notwendige Öffnungskraft auf verschiedenen Öffnungswegen erhöht und so dem Benutzer eine genaues Feedback der eingesetzten Kraft gibt
• – durch die konstruktive Auslegung des Brems- und Feststellmechanismus zusätzlich eine individuelle Einstellung der Öffnungskraft ermöglicht
• – dadurch für den Benutzer ausreichend leichtgängig zu bedienen ist, gleichzeitig aber eine sichere Feststellung in jeder Position gewährleistet
• – im Gegensatz zur herkömmlichen Auslegung nicht nur eine Endlagenfederung, sondern eine wirkungsvolle Endlagendämpfung erreicht.

The invention solves this technical problem by providing a slider and brake mechanism design

• - Provides a secure, in each position selectable door lock
• - Increased by the constructive design of the slide the necessary opening force on different opening paths and so gives the user an accurate feedback of the force used
• - Due to the structural design of the brake and locking mechanism additionally allows an individual adjustment of the opening force
• - This is sufficiently easy for the user to use, but at the same time ensures a secure statement in any position
• - In contrast to the conventional design not only an end position suspension, but achieved an effective cushioning.

These objects are inventively achieved in that the door detection is not done by a latching mechanism, but by a combination of slide and brake or locking mechanism that allows a door detection in any desired position (claim 1). The slider has different cross sections, the connections are made in the direction of increasing opening by ramps rising transitions. By means of this different cross-sectional selection for different sections, different braking or locking values can be achieved (claim 2). By correspondingly sharp increase in the slide cross-section shortly before reaching the end position, a strongly increasing opening force is achieved, the damaging peak load of the end stop of the door at Errei makes the end position impossible and thereby leads to an effective end attenuation (claim 3). The braking or locking mechanism consists of a tube with an opening through which the slider is guided, and by a sliding inside the tube pressure mechanism which presses the slider against the friction lining and thereby achieves the desired braking and locking forces (claim 4). This mechanism is adjustable by an adjustment to individually desired pressure values (claim 5).

embodiment

The invention consists of a slide ( 3 ), which at one end ( 3a ) with the A-pillar of the vehicle. is connected, and a brake and locking device (consisting of the components 14 . 2 . 4 . 5 . 6 . 7 . 11 . 12 . 13 ), with the car door at the standard attachment point of the tether ( 4a ), and that via the slider from the position 3a (Closing the door) up to the position 3b (maximum opening of the door) is running. So that different braking or locking values can be achieved, the slide has different cross sections: at the beginning of the opening of the door to the user the least possible resistance to be countered, then should be opposed over the following opening area, a constant resistance, which is also for fixing the Door is sufficient, and towards the end of the opening path of the cross section increases according to the required Enddämpfungskraft, so that the opening force must also rise accordingly. At the end of the opening stroke, the gate valve is still with a conventional stop ( 9 ) Mistake.

The actual braking or locking mechanism consists of the following parts. In a tube ( 14 ), which is provided with an opening through which the slider is guided, is a roller or a rolling bearing ( 4 ), which in a piston located in the piston-like sliding piece ( 5 ) is supported by a spring ( 6 ) pressed against the slide. This pressure causes the slider to move against a friction lining ( 2 ) pressed and braked or determined in this way. By a running in the pipe in a thread counterpart ( 7 ), the spring preload and thus the friction pressure can be varied continuously; when the friction pressure is set, the counterpart ( 7 ) through the locking screw ( 13 ) fixed. The piston-like sliding piece ( 5 ) is turned against rotation by the guide pin ( 11 ), which is guided in an axial groove of the piston-like sliding piece.

By the design of the slide with different cross sections are the areas of the opening path the door in which a) a possible low resistance (beginning of opening) b) constant resistance (main opening path) c) further or strongly increasing resistance (Endweg) brought shall be. With the constructive design of the slide, the according to vehicle type and user need can vary, the fundamental forces to be added the opening the door established.

By the possibilities of change the braking or locking mechanism can the friction values of the door arrester within the constructive design to the needs of the user (high vs. low locking force).
