Description

The Invention relates to a hinge fitting for the front flap of a passenger car, which front flap einendseitig on the hinge fitting and other end attached to a closure of the body, wherein the hinge fitting has a console attached to the body, which console carries a lifting member, which Lifting member in its stroke displacement of a normal use position in a stroke position a hinge support, on which the front door hinged, displaced in a distance position to the console, wherein the hinge-side attachment point is located on a substantially circular path moved around the shutter-side attachment point.

In order to achieve a pedestrian protection system, it is known in passenger cars, abruptly raise the front door or hood in an accident after previous sensory release by the passers in a distance position to the body, see. DE 101 11 146 A1 ( 9 and 10 ). The there carrying the front door hinge is designed in the form of a four-bar hinge. The hinge carrier is formed by two links, wherein the handlebar, the console side arranged lifting member engages.

the The invention is based on the object, the structure a generic hinge fitting simpler to exclude from the trouble-free Impairing function Constraining forces.

These Task is first and essentially a hinge fitting with the features of claim 1, with the fact that the hinged carrier is inserted on the lifting member hinged compensation handlebar, with the front door a Einelenkscharnier forms, with the position of the compensation link in the normal use position by a captive means assigned to the console is fixed, which captive means when leaving the normal use position such except Effect occurs that the position of the compensation driver only by the Trajectory of lifting member and hinge-side front flap attachment point is determined.

The objects the further claims are but explained below with reference to the subject-matter of claim 1 even in their independent Be meaningful.

According to such a design, a generic hinge fitting simple, reliable working structure is created. The hinge carrier now forms an articulated on the lifting link compensation arm. In conjunction with the front flap of the compensation handlebar is a single-pivot hinge, so that the front door hinge is a cost-effective component to be manufactured. In addition, there is still a weight saving. Then it is prevented that in a sudden start-up of the front door in the hinge area constraining forces are avoided, since the hinge point between compensation handlebar and front door can move on a circular path of movement about the shutter-side attachment point. In the normal use position, however, the compensation link is stabilized in its position. This is done by means of the shackle associated with the console. In this normal use position, the front door can be opened and closed in the usual manner. Only when leaving the normal use position occurs the compensation link from the operative connection to the captive. This is done in such a way that afterwards the position of the compensation link is determined only by the movement path of the lifting member and the hinge-side front flap attachment point. This excludes the aforementioned compulsory forces. To a simple structure contributes to the fact that the front flap, the hinged thereto compensation handlebar and articulated with the balance arm and the console link member form a Dreilenkerket te. According to the invention, it is further provided that the lifting member is a pivoted on the console pivot lever to which a lifting force, in particular a biased spring accumulator or a pyrotechnic charge attack. Due to this configuration, the pivot member forming the lifting member may be abruptly displaced about its pivot point and thereby displace the hinge carrier in a stroke position taking along the front flap in the hinge side area. The captive is also very simple in its construction. The essential components of the restraining means are a pocket and a protrusion entering it. The latter is the case in the normal use position. In detail, the procedure is such that the pocket is assigned to the console and the projection is a hinge point of adjacent pins of the compensation link. In order for the normal use position to always be able to be brought out of the stroke position in accordance with the regulations, a control strip arranged adjacently to the pocket is provided, which cooperates with a control pin assigned to the compensation link. Therefore, care must always be taken that the pin of the compensation handlebar dips as intended into the pocket. For the purpose of limiting the stroke by simple means takes the particular double-arm compensating handlebar in the stroke position with the lift lever designed as a lifting member on strike position. To ensure that after the use of the pedestrian protection system back to normal use position is reached, an attacking on the lifting member, stretched in the lifting operation return spring is provided for the delayed return of the lifting member after a loss of effect of the lifting force. The damping function in the event of a collision with the front flap is not eliminated by this return spring, so that the pedestrian protection system works as intended in the event of an accident.

Farther The invention relates to a holding arrangement in a spring-biased Discharge standby position held actuator, wherein the holding assembly by shifting a trigger member from her Hal setting in a release position for the actuator is spent, with the trigger member is driven by a rotary motion of an electric motor.

Such a holding arrangement is the subject of a non-prepublished patent application ( DE 103 05 330.1 ). The holding arrangement includes two links and a rotatably driven by an electric motor trigger member. By driving the same handlebars are controlled so that they release the actuator from the spring-biased discharge ready position. Such a system or such a holding arrangement is primarily used in pedestrian protection systems of motor vehicles. In an accident with a passerby z. B. then sensor-controlled, the front flap abruptly raised in a distance position before the passerby strikes the front door with a body part. Thus, the front flap placed in the spaced position provides a compliant component which helps to reduce injuries.

Of the Invention is based on the object, a generic holding arrangement from always reliable specify the working function.

to solution This object is inventively proposed that the drive via a intermediate freewheel gear is done so that the electric motor for test purposes in reverse direction without actuation of the tripping member can turn. Due to this configuration can always for testing purposes the functionality the holding arrangement will be checked without this being required, the spring biased discharge ready position of the actuator repealed. The test takes place where the low tripping forces are present. There must be reliability always guaranteed be. It is for this purpose the electric motor initiated, however so that it rotates in reverse direction. Since then the drive via an interposed Freewheeling member, the trigger member is not taken. It remains in its inactive position without affecting the holding arrangement. That means that also the actuator can not take effect, for example, to act on a hood, be it an associated closure or a hinge. in the Detail, the holding arrangement is constructed so that it is an immediate on the actuator engaging holding element and having a supportive support element, on which the latter the trigger member attacks. So that the actuator can be effective, must first the trigger member of the initiated electric motor to be moved. By the trigger member becomes the support element shifted, which shift to that on the actuator engaging retaining element transmits. hereby the spring-loaded actuator is released for rotation. Control technology favorable it turns out that the trigger element one against his triggering direction spring-loaded plunger is. A rotary displacement of the electric motor is therefore in a longitudinal movement of the trigger member implemented. The longitudinal displacement of the trigger member or the plunger happens doing so by a plunger shifting cam in the form of a rotary wedge. This means that when in reverse direction driven electric motor due to the free-wheeling a stoppage of Control curve is accompanied and thus no displacement of the plunger takes place. Drive technology is favorable it, when the freewheel gear between a cam forming the Cam carrier and motor shaft sits. The freewheel gear is preferably the cam carrier incorporated, so that the design can be very crowded. In order to always a defined starting position of the cam carrier in Reference to the trigger member or Plunger is present, the control cam carrier running on block is shifted back spring-controlled. A optimal functional solution results from the fact that the electric motor at each engine start for one short time is turned in the opposite direction. Thus, there is a constant monitoring the holding arrangement instead. If there is a fault, this will the driver displayed.

thereupon the invention relates to a hinge fitting for the front flap of a passenger car, with a console attached to the body, one of the console associated lifting member, which lifting member with a trigger-controlled in effect lifting force a hinge support from a normal use position shifted in a stroke position, on which hinge carrier the Front flap is hinged.

Such known hinge fittings are used to implement a pedestrian protection system to abruptly shift the front door in a distance position in an accident before the passers encounter the motor vehicle. After tripping then remains the hinge fitting in the stroke position and must be subsequently returned to the normal use position.

Of the Invention is based on the object, a generic hinge fitting to design use-advantageous.

to solution this invention task proposes the invention before, a reset device to provide the hinge fitting, which the hinge carrier automatically in the Normal use position shifted back. The reset device is designed to provide the security function of the hinge fitting not affected in the stroke position. After exercise the backup function transfers the Reset device the hinge carrier automatic in the normal use position. That means that then the front door opened in the usual manner and can be closed again. It does not take the disadvantage on that for some reason the front door in the stroke position remains. In detail, the procedure was such that the backsliding delayed after Reaching the stroke position takes place. So always with previous Lifting the front flap in the stroke position the necessary force for returning the Front door is in normal use position is one used in the stroke displacement tensioned return spring. to Achieving a crowded Construction is provided according to the invention, that the return spring a coil spring is. One end of the same is on the body side set while the other end cooperates with the lifting member. Along with the same pivoting in the stroke position is also the Return spring tense or charged. So that the return device is not against the lifting force needs to work, namely at the provision occurs the reset device after a loss of effect of the lifting force in effect. Especially it is advantageous according to the invention when the lifting force applied by a pyrotechnic charge is, with the combustion gases retarded from the discharge chamber escape and thereby released the effect of the restoring device becomes. It may accordingly the reset device continuously working by expelling the combustion gases from the Discharge chamber through a correspondingly sized opening. An alternative solution is characterized in that the hinge carrier in the stroke position in a easily overcome Rest is held, taking over this rest the restoring device brings into effect. This increases the safety value of the hinge fitting. Once a certain Force acts on the front flap, is accompanied by the easily overcome catch canceled. Only then does the return device come into action and bring the hinge bearer from the stroke position back to the normal use position. Then The front door can be opened and closed in the usual manner. It is according to the invention here Such a structure that the lifting member is a Hubschwenkhebel forms, which tied in the non-use position by a locking member is, wherein this locking member displaced by a transmission lever being, with the transmission lever transmits its torque to the Hubschwenkhebel. Accordingly, the transmission lever fulfills another Function, in addition to the displacement of the Hubschwenkhebels this fixing Locking member triggers. It is also envisaged that the transmission lever in the course of the release of the locking member an idle rotation relative to the Hubschwenkhebel performs, at the one between transmission lever and Hubschwenkhebel arranged spring is tensioned. This strives to the transmission lever always in a starting position relative to the Hubschwenkhebel too relocate. About that Be delayed beyond from the transmission lever a locking lever entrained, which in the lifting position with a locked on the console side latch and on which the return spring attacks. However, the latter can only take effect if the Locking pawl is acted upon in their release position. this happens in an advantageous manner according to the invention in that the locking lever in the detent holding latch in the course of a downward displacement of the hinge carrier unlatched. The displacement of the hinge carrier leads to a take along the Hubschwenkhebels. So that its pivoting on with transferred to him interacting components can, the Hubschwenkhebel forms a control edge for unlatching the pawl off. The locking lever associated with the return spring can now take effect. In the course of the rotary displacement of the locking lever This can be active with this associated drive jack, with the the locking lever on its return displacement engages the Hubschwenkhebel and this transferred to its initial position, which the normal use position of the front door corresponds. accompanying will over the Hubschwenkhebel and transmission lever connecting spring of the transmission lever returned to its original position, whereupon the locking member can secure the Hubschwenkhebel.

Farther the invention relates to a hinge fitting for the front flap of a passenger car, with a attachable to the body console and on the Front flap hinged hinge carrier, which by means of a Actuator controlled trigger by the action of a lifting force from a normal use position is displaced into a stroke position and by opening or closing operation of the Front flap with the help of an auxiliary link again zurückverlagerbar is.

The non-prepublished patent application 103 310 47.9 suggests that in the hub position brought hinge support by pivoting operation of the front door is returned to its normal position of use. In the case of the opening movement of the front flap which takes place in the process, the auxiliary link designed in the form of a tension member forms a pivot about which the front flap pivots when it is opened. This results in that the hinge carrier reaches the starting position or normal use position.

Of the Invention is based on the object, the return of the hinge carrier against the force of the discharged energy storage with little effort to achieve.

These Task is first and essentially a hinge fitting with the features of claim 29, with it being pointed out, one according to a first, the lifting member assigned and a second, the auxiliary link associated Freilaufgesperres enabling recoverability provided by repeated, short-term pivoting of the front door.

according to Such a design is a generic hinge fitting of high Use value created. After an accident-related effective date the lifting force is through this the lifting member and thus the hinge carrier in the upward direction shifted, with the front door within a few milliseconds abruptly in their stroke position, so a distance to the body arrives. Since the lifting force of a power storage in the form of a relaxed spring is applied, this must be in the return shift of the hinge carrier recharged from the stroke position to the normal use position become. The applied force is facilitated by repeated, kurzwegiges pivoting of the front door, which means of the auxiliary link member associated Freilaufgesperres is feasible. It does not have to be complete the front door is moved to an open position. When relocating prevents one of the two freewheel mechanism that the lifting power brings the lifting member back into a lifting position. In detail is the hinge fitting designed so that the freewheel lock in the normal use position are out of action and in the Final phase of Hubverlagerung be controlled in effect. you take accordingly a ready position a, so when subsequently opening and Shut down the front flap the downward displacement of the hinge carrier he follows. It is according to the invention care worn that the Freilaufgesperre in the final phase of the return movement except Effect be brought and the lifting member of a holding member in the normal use position is maintained. Regarding the construction and manufacture of the hinge fitting, it proves to be advantageous that at least one of the Freilaufgesperre is a ratchet. For a trouble-free function The facts ensures that the ratchet teeth of the at least one ratchet mechanism lying on a circular arc. Then, it is an effective advantage that the auxiliary joint member is a one of the ratchet teeth exhibiting toothed segment and the hinge bearer or the front flap connecting rope, chain or a pull rod is. It is achieved by opening the front door Displacement of the lifting member takes place, whose backward displacement by the one Ratchet lock is prevented. So that the pawl in her each end position remains pawl of the ratchet mechanism by means of an over-center spring either in the operative position or in the non-operative position charged. The control of the pawl takes place in that the at least a pawl has a control projection, with which they of two countersteering projections is controlled in the respective operating position. According to the invention, it is provided that the counter tax projections, which are associated with the lifting member designed as a pivot lever, controlling the pawl associated with the lifting member. Furthermore, the the pawl associated with the auxiliary link is controlled by counter projections; one of which the lifting member and another the hinge carrier or associated with the flap. The front flap associated counter projection then has the task, after complete relocation of the lifting member bring the pawl in question to the non-operative position. After all There is an advantageous feature is that the toothed segment the Hubgelenkgliedes about the same axis as the lifting member forming Hubschwenkhebel pivots and in the freewheeling direction of the associated freewheel gear is spring-loaded. With raised hinge carrier and while the shift back the same can be used in the closing direction pivoting front flap the relevant tooth segment ratchet-like run over the assigned pawl, after that in a support position during the opening movement the front door to kick, which is a subsequent downward movement of the hinge carrier conditionally.

Of Furthermore, the invention also relates to a hinge fitting for the front door a passenger car, with a fastened to the bodywork Console and hinged to the front flap hinge carrier, which trigger-controlled by means of a lifting member by the action of a lifting force from a normal use position is displaced into a stroke position and by opening or closing operation of the Front flap with the help of an auxiliary link again zurückverlagerbar is.

The invention has for its object to make the structure of such a hinge fitting simple at high reliability of the same.

to solution This object is inventively proposed that the auxiliary joint member a is provided with a slot pull or push rod. The slot allowed after previous release, which, for example, in an accident of the passenger car with a passerby occurs that the lifting power the hinge carrier disability-free and thus the front flap in the distance position can lift to the body. This happens very fast, so that before hitting body areas the passers on the front flap already this already their distance position holds. Has the front flap its shock absorbing after an accident Function exercised, The front flap closure can be opened. At the then taking place opening swing displacement the front flap, the auxiliary link provides the hinge point for the front door so that the short lever arm extending beyond it serves to the hinge carrier to shift to its original position against the lifting force. by virtue of the relatively long lever arm of the front flap, on which, for example. the driver attacks, lets This process can easily be done. A double function Fulfills the pull or push rod characterized in that the length of the elongated hole the Aufschwenkweg corresponds to the front flap in the hinge area. In the usual manner the front flap can be pivoted about its hinge point, for the purpose of opening and closing the front flap. In addition to Joint formation when swinging the front flap for the purpose of provision of the hinge carrier becomes then through the slot of the pull or push rod, the stroke displacement the front flap in the hinge area is limited after release. For the purpose of realization a simple design is an engaging in the slot console side Provided pin. The lifting gear, which acts on the hinge carrier, can be designed differently. So there is the possibility that the lifting gear is a single or multi-link gearbox.

Of Furthermore, the invention also relates to a hinge fitting for the front door a passenger car, with a bang on the body Console and hinged to the front flap hinge carrier, which by means of a hinge support and hinged to the console lifting member by the discharge effect a force acting on the lifting member force memory, in particular in the form a pyrotechnic element from a normal use position is displaceable in a stroke position.

Of the Invention here is also the object of a generic hinge fitting nutzsvorteilhafter weiterzugestalten.

Is solved this task also here of each individual claim alone as well as any combination of any claim with each any other claim.

Of the Claim 44 looks first and, in essence, that by a the hinge carrier in the Normal use position fixed to the console captivating holding device, which by the discharge effect of the energy storage before Attack on the lifting member of the bondage position in a release position is relocatable.

Such a hinge fitting is preferably designed such that it forms a holding device on a console. The holding device is formed by a pawl which is rotatably mounted against the restoring force of a spring. The pawl engages over a locking shoulder of a handlebar with a pawl. The locking shoulder is acted upon by means of a handlebar acting on the handle retaining spring against the locking hook. The pawl is associated with a trigger arm, against which acts one end of the force accumulator. After the displacement of the holding device in the release position, the end of the force accumulator immersed in a niche of the lifting member. The energy accumulator dives into the niche of the lifting member to pivot it in the lifting position. The hinge fitting forms a control lever, which is hinged to the console and the hinge support, so that the console, the control lever, the lifting member and the hinge support form a four-bar linkage. The control lever forms a stop which defines the stroke position together with a counter-stop of the console. In the stroke position, the control lever locks with a detent spring. From a second arm of the control lever, a stopper is formed, which forms a latching lug. The locking lug cooperates with a locking spring associated with the console. By an opening operation, the front door is moved back into the normal use position with the help of an exciting in the displacement in the lifting position cable. It is also possible to use an articulated lever or a lever instead of a rope. When opening the front flap in the stroke position acting on the control lever catch is overcome and the energy storage by a control member shifted back. The control element is formed by a control cam of a hinged on the front flap hinge carrier to which the rope is attached. The energy storage device is in the normal use position with the hinge closed between the hinge carrier attached to the front flap and the console. The energy storage is encapsulated laterally between levers of the lifting gear. The energy storage is connected to the hinge fitting so that it is easily replaceable. By laterally projecting axle extensions, which are formed by the energy storage, the Kraftspei bayonet be associated with a Lagerhöhlung the console. One end of the energy accumulator engages the control arm of the holding device. The end of the energy storage is formed by a tee. After the release of the holding device, the T-piece enters a niche of the lifting member and in the normal use position, this has a movement distance to the bottom of the niche of the lifting member. For displacement of the lifting member in the stroke position, the bottom of the T-shaped end is acted upon. The energy accumulator can also be moved back by means of a push-back slide, wherein the push-back slider is hinged to the hinged on the front flap hinge carrier. The return pusher is a cam-controlled pusher.

below will be first an embodiment of the invention explained with reference to the drawings. It shows:

1 the front end of a passenger car, in which, under schematic illustration, the front flap is raised from its normal use position drawn with full lines into a stroke position shown by dash-dotted lines,

2 in an individual view the hinge fitting in its normal use position,

3 one of the 2 corresponding representation, but during an intermediate position of the hinge fitting in the stroke displacement of the lifting member and

4 the hinge fitting in the lifting position engaging front flap.

With the numeral 1 is referred to as a bonnet serving front flap. By means of an in 1 schematically illustrated hinge fitting 2 can the front door 1 be moved abruptly in a dot-dashed illustrated distance to the body from her drawn with full lines closure position. In this displacement in the distance position moves the front flap-side hinge point 3 on a substantially circular path around one of a front flap closure 4 formed attachment point. This sudden lifting of the front door 1 takes place in particular in an accident with a passerby, in consequence of one or more sensors arranged in the front region of the passenger car 5 ,

The front flap 1 There is a hinge fitting on each side 2 assigned. In detail, each has hinge fitting 2 a fixed to the bodywork of Perso motor vehicle console 6 , It is about a triangular shape of the console 6 in front. In the area of the vertex closer to the front of the passenger car is the hinge axis 7 for a trained as a pivot lever lifting member 8th , Incidentally, the lifting member 8th designed as a one-armed lever. The hinge axis 7 and the lifting member 8th represent an interconnected unit. At the pivot pin 7 take that one end 9 ' a wound to a coil spring return spring 9 at. The other end 9 '' the return spring 9 relies on a console-side projection 10 from. The lifting member 8th by the way invites towards the rear edge of the front flap 1 out. In the normal use position closes the slightly sloping lifting member 8th to the horizontal an angle of about 10 °. At its free end is the lifting member 8th with a pivot pin 11 provided, which a hinge carrier 12 articulated with the lifting member 8th combines. The hinge carrier 12 forms a double-arm compensation handlebar. The shorter, downward-pointing handlebar arm 12 ' is one with a stop 13 forming bending. The latter extends in the plane of the lifting member 8th , The longer handlebar arm 12 " carries at its free end the pin-like hinge point 3 on which the front flap 1 hinged. It can be seen that the lifting member 8th , with this articulated balance handlebar 12 and the hinged front flap 1 form a three-link chain.

In the normal use position, cf. especially 2 , is the location of the compensation handlebar 12 through one of the console 6 associated bondage agent 14 fixed. The latter is such that when leaving the normal use position so out of action, that the position of the compensation driver 12 only by the movement path of the lifting member 8th and the hinge-side front flap attachment point 3 is determined. The trajectory is characterized by a surface F, which is circular to the closure-side attachment point 4 runs.

The the lifting member 8th forming pivot lever is under the action of a prestressed spring accumulator or a pyrotechnic charge. The corresponding spring force is indicated by an arrow 15 characterized. This spring force 15 occurs sensor-controlled abruptly in action.

That at the console 6 fixed captive means 14 has a U-shaped, open at the top pocket 16 , in which in normal use position a projection 17 of the equalizer 12 dips. Regarding the lead 17 it is a pin, the form-fitting between the two U-thighs 16 ' the pocket 16 rests. At its free end, the U-legs widen 16 ' funnel-shaped. The orientation of the U-legs 16 ' runs approximately parallel to the path of movement of the hinge point 3 ,

Adjacent to the bag 16 is a control bar 18 arranged. Their orientation is also adapted to the trajectory F. The control bar 18 surmounts the bag with its upper end 16 , The bottom of the control bar 18 is about such a measure on the bag 16 before, which measure corresponds approximately to the length of the bag. With this control bar 18 acts on the compensation handlebar 12 attached control pin 19 together. Due to this configuration is a defined normal use position of the compensation handlebar 12 in front. With respect to the normal use position is that in which the front flap in the usual manner around the hinge point 3 swings.

The following mode of action occurs:
For example, in an accident with a pedestrian occurs sensor-controlled on the lifting member 8th attacking spring force 15 in action. This leads to a pivoting of the lifting member 8th counterclockwise connected with a driving of the compensation handlebar 12 or hinge carrier in the upward direction. This leaves the lead 17 the pocket 16 , The control pin 19 moves in the intermediate position according to 3 still along the control bar 18 , During this pivotal displacement of the lifting member 8th counterclockwise, the return spring 9 curious; excited. The stroke position of the front flap 1 is reached when the bend 13 stop limiting against the lifting member 8th occurs, cf. 4 , Also from this it can be seen that the hinge point 3 has moved on the circular path F. This distance position of the front flap 1 serves to alleviate a possible impact in an accident. After a loss of effect of the lifting force acting on the lifting member 15 done by the return spring 9 a delayed return of the lifting member 8th in the starting position, which in the dash-dotted lines in 4 is indicated. This is done via the control bar 18 and bag 16 the compensation handlebar 12 or hinge carrier shifted back to the normal use position.

In the 5 and 6 an embodiment of a holding arrangement according to the invention is illustrated. It shows:

5 a held by a holding device in a spring-loaded Endladebereitschaftsstellung actuator supported by a lifting module, and

6 in a separate representation of the electric motor with removed housing shell, indicating the trigger member and cooperating with this control cam.

In 5 is with the numeral 30 as a whole a lifting module called. This can be used, for example, after painting a passenger car in the hinge area of a front flap to lift, for example, in an accident, the hinge-side end of the front flap in a distance position. This must happen abruptly within a few milliseconds.

The lifting module 30 has a screw-on console 31 , This stores around an axis 32 a firmly connected with her, one-armed designed actuator 33 , An unillustrated spring force loads the actuator 33 in the clockwise direction. On the axis 32 also sits on the opposite side of the console a fork trap 34 for cooperation with associated, not illustrated hinge components.

For fixing the actuator 33 in the spring-biased position serves a holding arrangement 35 , The latter is due to relocation of a trigger member 36 from its holding position into a release position for the actuator 33 brought.

For controlling the triggering element 36 is an electric motor 37 used. The drive of the same on the trigger member 36 takes place via an intermediary, in 6 dot-dashed freewheeling link 38 , The latter makes it possible for the electric motor 37 for test purposes in reverse direction without actuation of the tripping member 36 can turn.

In detail, the holding arrangement has 35 a directly on the actuator 33 engaging holding element 39 in the form of a double-armed lever. The longer lever arm 39 ' makes a mouth 40 out, in which the free end of the actuator 33 protrudes. The shorter lever arm 39 '' of a pivot pin 41 the screw-on console 31 pivoting holding element 39 is from a support element 42 supported. The support element 42 stores around a screw-on console-side joint 43 , An attack 44 limited by the lever arm 39 '' forced rotary displacement. With one arm 45 protrudes the support element 42 in the trajectory of the trigger member 36 ,

The electric motor 37 is in a double shell housing 46 accommodated. 6 shows the position with a housing half is omitted. It can be seen that the trigger member 36 one at the front end of the housing 46 guided, opposite its triggering direction spring loaded ram is. The spring in question is as a compression spring 47 designed, which endeavors, the plunger-like trigger member 36 to move in the housing inward direction. The inward end 36 ' of the trigger member 36 acts with a control curve 48 in the form of a rotary wedge together. Trained is the control curve 48 on a cam carrier 49 , This takes in its interior, the freewheel gear 38 on. In this way, the freewheel gear 38 between the cam 48 training helm carrier 49 and the motor shaft 50 arranged. On the motor shaft 50 also sits a torsion spring 51 , which endeavors to block running on the cam track 49 spring-loaded relocate. To control on block forms the cam carrier 49 in the area of the highest point of the control curve 48 a stop shoulder 52 off to interact with the inbound end 36 ' the plunger-like trigger member 36 ,

The triggering of the holding arrangement 35 happens within a few milliseconds. For triggering receives the electric motor 37 the impulse to rotate in one direction of rotation, the inner end 36 ' of the trigger member 36 from the control curve 48 in the dash-dot position according to 6 is relocated. In this forward displacement, the support element 42 around the joint 43 rotated counterclockwise, wherein the support element 42 from the support position to the holding element 39 occurs. It is thereby the actuating arm 33 , which is under considerable spring action, released for rotation.

Preferably, the electric motor 37 included in the starter circuit of a passenger car. That means the electric motor 37 can be turned in the opposite direction at each machine start for a short time. As a result of the freewheel gear 38 is accordingly the cam carrier 49 not taken, so that the trigger member 36 remains in its zurückverlagerten position and accordingly the holding arrangement 35 not activated. Due to this configuration, a secure functioning of the holding arrangement is always ensured. If this is not the case, this can be visually and / or acoustically displayed at a machine start.

According to the embodiment according to 7 and 8th finds the hinge fitting 60 Use on a passenger car and serves, for example, in a passers-by accident, the hinge-side region of the front door 1 abruptly to move in a distance to the body. This happens within a few milliseconds, so on the front door 1 impinging body areas of a passerby force an evasive displacement of the front flap while reducing a risk of injury.

The hinge fitting 60 has a to be fastened to the body, dash-dotted illustrated console 61 , This stores around a pivot pin 62 a multi-arm designed lifting member 63 , By means of a lifting force is an articulated the lifting member 63 associated hinge carrier 64 from the normal use position according to 7 in the stroke position according to 8th relocated. This hinge carrier 64 carries at its upper end the hinge pin 3 so that the hinge is a single pivot hinge.

The lifting member 63 engages at the lower end of the hinge carrier 64 by means of a pivot pin 65 at. In the middle area of the hinge carrier 64 is another pivot 66 provided for coupling an approximately parallel to the lifting member 63 extending handlebar 67 , which by means of a hinge pin 68 at the console 61 hinged.

The lifting member 63 is a reset device 69 assigned. The latter includes one on the pivot pin 62 arranged, designed as a spiral spring return spring 70 , The outer end of the same is supported on a console-side pin 71 while the inner end is fixed to the pivot pin 62 connected is. This rotatably carries the lifting member 63 , By the return spring 70 becomes the lifting member 63 strained in the clockwise direction. In normal use position, the lifting member is supported 63 at a stop 72 the console 61 from, cf. 7 , This position is secured by a locking member 73 , wel ches around a cone 74 the console 61 stores and counterclockwise direction is acted upon by a non-illustrated locking member spring. The locking member 73 engages behind a locking arm in the locked position 75 designed as Hubschwenkhebel lifting member 63 , On the locking member 73 is then a driving pin 76 established.

To the pivot pin 62 stores a transmission lever 77 , At this the pestle grips 78 a pyrotechnic working, on the console 61 fixed device 79 at. The transmission lever 77 forms a control curve 80 out to interact with the driving pin 76 of the locking member 73 ,

Angle of rotation offset to the control curve 80 is the transmission lever 77 an attack 81 formed. This extends with a small angular distance in front of a driving arm 82 the Hubschwenkhebels 63 , Between the stop 81 and the Hubschwenkhebel 63 is a tension spring 83 strained, causing the transmission lever 77 in the normal use position in a defined position to the Hubschwenkhebel 63 is held.

The pyrotechnic device 79 is constructed so that the combustion gases escape from the discharge chamber delayed, whereby the effect of the restoring device is released.

The above-described embodiment of the hinge fitting 60 works as follows:
Receives, for example, in an accident with a passerby the device 79 sensor-controlled the ignition pulse, so suddenly drives the plunger 78 driven by the pyrotechnic charge, and tows the transmission lever coupled with it 77 With. In the initial phase of the rotary displacement of the transmission lever 77 acts on the control cam 80 the driving pin 76 of the locking member 73 and lifts this from the locking connection to the latching arm 75 the lifting member 63 out. In the course of the rotary displacement of the transmission lever 77 attacks its attack 81 after a slight idle rotation on the driving arm 82 the Hubschwenkhebels 63 and pivots it counterclockwise while simultaneously lifting the hinge carrier 64 and thus the front flap 1 in the stroke position according to 8th , In this process, the return spring 70 curious; excited. Due to the delayed escaping from the discharge chamber combustion gases, the return spring 70 not immediately effective. The stroke position of the front flap in the range of milliseconds 1 leads to a muffled impact in an accident with a passerby. Thereafter, the front door is delayed by means of the return device 69 returned to the normal use position, the combustion gases continuously leave the discharge chamber. The return spring 70 converts the Hubschwenkhebel 63 in the stop position, ie in the normal use position. This shift is via the Mitnehmerarm 82 on the transmission lever 77 transfer. In cooperation with the tension spring 83 then the starting position according to 7 brought about again.

The embodiment according to 9 to 14 is similar in structure to the previous embodiment. The same components are therefore provided with the same reference numerals.

Divergent is now the hinge carrier 64 held in the stroke position by an easily overcome catch. Only after overcoming this rest occurs in this version existing, not shown restoring device 69 in effect. Deviating stores on the pivot pin 62 in addition a locking lever 84 , At this now engages the inner end of the return spring 70 and loads the locking lever 84 in the clockwise direction. The locking lever 84 has a driving shoulder 85 , which delays after acting on the Mitnehmerarmes 82 is charged. Angular offset to the driving shoulder 85 Stores the locking lever 84 a take-along jack 86 , which in the normal use position in a recess 87 of Mitnehmerarmes 82 intervenes. The driving jack 86 then carries a control pin 88 which is in the path of movement of a control arm 89 the transmission lever 77 lies.

Then is deviating in this embodiment, the driving arm 82 designed to be longer in the radial direction. This forms a control edge 90 out. Its task is a latch 91 to control which is a console-side journal 92 is stored and which a driver projection 93 formed. This latch 91 acts together with a recess 94 of the detent lever 84 ,

All pawls 73 . 86 and 91 are spring loaded and have the desire to step into their rest position.

The hinge fitting according to 9 to 14 works in the following way:
To bring about the distance position of the front door 1 the initiation of the pyrotechnic device takes place 79 , The transmission lever will be connected 77 pivoted counterclockwise, which by means of its control cam 80 the locking member 73 disengages, cf. 10 , The attack occurs concurrently 81 in front of the driving arm 82 , Furthermore, the control arm acts 89 the control pin 88 the takeaway latch 86 and lifts them out of the recess 87 of the Rasthe bels 84 out.

In the course of the rotary displacement of the transmission lever 77 becomes after a further lifting displacement of the front flap 1 the position according to 11 reached. This indicates that now the attack 81 the transmission lever 77 before the entrainment shoulder 85 of the detent lever 84 has entered and leads to entrainment thereof associated with a tensioning of the return spring 70 , In the course of the drive displacement, the stroke position is in accordance 12 realized. About the hinge carrier 64 is accordingly the front flap 1 has been raised completely in the hinge position in the distance position. Furthermore, the locking lever 84 the return spring 70 completely curious. However, this can not be effective because the latch 91 in the recess 94 of the detent lever 84 has fallen. Then, in this position, the tension spring 83 curious; excited. The hinge carrier 64 is held in this stroke position in an easily surmountable rest. When loading the front flap 1 becomes on its downward displacement over the hinge carrier 64 the Hubschwenkhebel 63 shifted in the clockwise direction, with its control edge 90 the driver lead 93 the latch 91 charged, cf. 13 , and later this one picks up what's out 14 can be seen. Due to the pivotal displacement of the lifting member 63 in the clockwise direction, the driving latch 86 in the recess 87 the lifting member or Hubschwenkhebels 63 come to mind. About the locking lever 84 in the clockwise direction restoring spring 70 becomes the Hubschwenkhebel 63 according to its original position 9 turned back. Then this is the transmission lever 77 taken with the pestle 78 expels the combustion gases located in the combustion chamber. After the transmission lever 77 resumes its initial position, the locking member 73 come in while the spring 83 the transmission lever 77 and the Hubschwenkhebel 63 holds in the starting position, in which the free travel between transmission lever 77 and lifting lever 63 is available.

21 a view of the hinge fitting with console shown.

The with the numeral 1 designated front flap is by means of a hinge fitting 2 assigned to a passenger car. It is a Einelenkscharnier, in which the front door 1 around a hinge point 3 is displaceable, which at the upper end of a hinge carrier 101 located.

Worn is the hinge carrier 101 from a four-bar hinge. The upper handlebar 102 the same is on the one hand by means of a pivot pin 103 on a console 104 hinged. The other end of this handlebar 102 engages in the middle region of the hinge carrier 101 by means of another pivot pin 105 at. The further link is formed by a lifting member 106 , This pivots about a console-side pivot axis 107 and engages with its free end in the lower part of the hinge carrier 101 by means of a pivot pin 108 at.

In the normal use position of the hinge carrier 101 is the lifting member 106 by means of an arrow 109 illustrated holding member fixed. Furthermore, engages the lifting member 106 one by arrow 110 indicated power storage on. Its task is, in an accident of the passenger car with a passerby the lifting member 106 within a few milliseconds to pivot while driving the hinge carrier 101 and relocation of the front door 1 in a distance to the body.

The lifting member 106 is a first Freilaufgesperre 111 assigned. Furthermore, a second Freilaufgesperre 112 used, which is designed as a traction rope auxiliary link 113 assigned. Both freewheeling mechanism 111 and 112 are in the normal use position, cf. 15 , except Effect and are controlled only in the final phase of Hubverlagerung in effect.

Every freewheeling lock 111 . 112 is designed in the embodiment as a ratchet mechanism. The ratchet teeth 114 of the first freewheeling lock 111 be from the lifting member 106 formed and lie on one around the pivot pin 107 laid circular arc. The ratchet teeth 114 work together with a pawl 115 which are around a console-side pin 116 is stored and end the ratchet teeth 117 formed. By means of a pin 116 assigned, schematically indicated Übertotpunktfeder 118 can the pawl 115 take two end positions. Near the articulation point of the pawl 115 the pawl forms a control projection 119 out, with which they of two countersteering projections 120 . 121 the lifting member 106 is controlled in the respective operating position.

Also the second freewheeling lock 112 is with a pawl 122 fitted. This is also by means of an over-center spring 123 held in the respective operating position. To control the pawl 122 is this with rotational angle offset from each other control projections 124 . 125 equipped with counter-projections 126 . 127 interact. The counterproposal 126 is located on the lifting member 106 while the other counter-projection 127 the flap 1 assigned.

On the pivot axis 107 sits a ratchet teeth 128 having toothed segment 129 , The latter is loaded by an unillustrated spring in the clockwise direction. At the end pointing in the direction of rotation of the toothed segment 129 grips one end of the rope-like auxiliary link 113 which, after partially looping around the toothed segment on a boom 130 the front flap 1 is fixed.

By triggering the holding member 109 can the energy storage 110 become effective while the lifting member 106 around the pivot axis 107 pivot. It first turns the intermediate position accordingly 16 one. From this it can be seen that the opposing projections 121 and 126 their associated tax advances 119 . 124 the pawls 115 . 122 achieved. Furthermore, via the auxiliary joint member 113 the toothed segment 129 turned. The meshing is not yet brought about.

In the further course of the pivotal displacement of the lifting member 106 is the stroke position according to 17 reached. Then the hinge carrier has 101 moved completely upwards and thus the front door 1 transferred to the required From stand position. Then has the counter tax advantage 121 the lifting member 106 the pawl 115 by applying the control projection 119 brought into the operative position, which position by the Übertotpunktfeder 118 is maintained. Also the pawl 122 of the second freewheeling lock 112 then takes its active position by the counter-projection 126 the tax advantage 124 has acted upon.

After a shock absorbing function of the front flap 1 can the normal use position of the hinge carrier 101 be brought back again, by repeated, kurzwegiges pivoting the front door 1 , According to the position 17 is the toothed segment against displacement in the counterclockwise direction by a schematically indicated, console-side stop 131 secured. Now follows after opening the front flap closure, the opening shift of the front flap 1 , so the position according to 18 one. The lower end of the Zugseilartigen Hilfgelenkgeliedes 113 does not change his position. The upper end of the auxiliary link 113 which is there on the boom 130 is fixed, forms at this front flap opening a hinge point, wherein the lying beyond this hinge point end of the front door 1 the hinge carrier 101 displaced in the downward direction and thus the lifting member 106 while charging the energy storage 110 pivoted. Here the ratchet teeth overflow 117 the pawl 115 the ratchet teeth 114 the lifting member 106 to then intervene in the corresponding tooth gaps. The other pawl 122 remains ineffective.

Now, after the short opening shift of the front door 1 this again in an intermediate position according to 19 getting closed. The lifting member 106 is secured against pivoting counterclockwise, as the ratchet teeth 117 in conjunction with the ratchet teeth 114 prevent this. During the closing movement there is a downward displacement of the boom 130 instead of. The the toothed segment 129 loading spring can only a partial rotation of the toothed segment 129 cause, with its ratchet teeth 128 ratchet-like on the ratchet tooth 132 the pawl 122 walk by, then engage. It can now be made again an opening shift of the front door, wherein the position according to 20 established. The hinge carrier 101 has been completely relocated to the normal use position. Then also has the lifting member 106 moved to this position. So that it is not accidentally shifted back, occurs in this position, the holding member 109 in function and captivates the lifting member. In this opening operation is of the Gegensteuervorsprung 120 the tax advantage 119 the pawl 115 and transferred them to the ineffective position. The other pawl 122 on the other hand, it will not be until the next closing of the front door of the counter-projection 127 the front flap 1 at the tax tab 125 charged and placed in the non-operative position, which position by the Übertotpunktfeder 123 is secured.

The 22 to 25 show two further embodiments of a hinge fitting according to the invention. Show it:

22 the one embodiment of this schematically illustrated hinge fitting with befindlichem in the normal use position hinge support,

23 one of the 22 corresponding representation, wherein the front flap has moved due to accident in a distance position,

24 the following presentation of the 23 , after previous opening of the front flap-side closure and lifting the front flap for the purpose of resetting the lifting gear, and

25 a further embodiment of the hinge fitting, in which the lifting gear is a multi-link gear.

According to the embodiment according to 22 to 24 is the one with the numeral 1 designated front flap by means of a hinge fitting 2 arranged on a passenger car. The hinge fitting 2 includes a Einelenkscharnier, in which the front door 1 around a hinge point 3 is relocatable. The latter connects a carrier 140 the front flap and a screw jack. This includes a lifting member 141 , which by means of a pivot pin 142 on a chassis-side console 143 is articulated. The other end of the lifting member 141 engages by means of the hinge point 3 at the front flap 1 at.

With the arrow 144 a lifting force is indicated, which has the tendency, the lifting member 141 around its pivot 142 to pivot. But this can only happen due to the trigger, engages the lifting member 141 one with an arrow 145 schematically illustrated holding arrangement on. In an accident of the passenger car with a pedestrian sensor-controlled triggering of the holding arrangement 145 , so that then formed in the form of a charged spring force accumulator lifting force 144 abruptly the front flap 1 from the normal use position according to 22 can lift in a distance position. The front flap pivots about a closure-side attachment point.

Another component of the hinge fitting 2 is an auxiliary link 146 , The latter is a lifting member 141 cruising pull or push rod. It is over a journal 147 on the carrier 140 near the hinge point 3 hinged. The lower end of the pull or push rod 146 forms a slot 148 out. In this engages a console-side pin 149 one. According to the normal use position, the pin extends 149 at the upper end of the slot 148 , The slot 148 is so long that it is in the normal use position 22 opening the front door 1 around the hinge point 3 allowed.

23 illustrates the hinge fitting in the position, which after triggering the holding arrangement 145 results. This allows the lifting power 144 become effective, which the lifting member 141 pivots and thus the hinge point 3 with carrier 140 and front flap 1 pivoted about the fastener-side attachment point. This position occurs before the body or areas thereof of a passerby accidentally hit the front door. From the lifting position of the front flap 1 this can be returned to its normal use position. This happens after releasing the front flap closure. During the subsequent opening shift of the same thing, what 24 shows, forms the auxiliary link 146 with its axle journal 147 the hinge point for the front flap 1 , so that the short lever arm lying beyond it, pivoting of the lifting member 141 enforces against its spring load. In this case, the starting position of the lifting member 141 brought about which position by the holding arrangement 145 is secured. In this effect of the auxiliary joint member 146 supports the lower end of the slot 148 on the pin 149 from. After that, the front flap 1 closed again, the position is according to 22 one.

The second embodiment of the hinge fitting 2 ' according to 25 is similar in structure to the first embodiment. The same components bear the same reference numbers. Notwithstanding, the lifting gear is now a multi-joint transmission, namely a four-bar linkage. It contains two superimposed handlebars 150 . 151 , where the lower handlebar 150 the lifting member 150 forms. This is at the console 143 around a hinge axis 152 arranged pivotally. At the lifting member 150 or handlebars picks up the lifting power 144 at. This can be applied by means of a force storage spring, which may have different shape, such as one on the hinge axis 152 arranged spiral spring.

That of the hinge axis 152 opposite end of the lifting member 150 engages by means of a pivot pin 153 on a hinge carrier 154 at. Its upper end is by means of the hinge point 3 with the console 1 hinge-linked. On this hinge carrier 154 the holding arrangement now works 145 , which after triggering the immediately afterwards following pivoting of the lifting member 150 According to the charged energy storage or lifting power 144 allowed.

In the middle region of the almost vertical position engaging hinge carrier 154 is the hinge point 155 between handlebars 151 and hinge carrier 154 , The other end of the handlebar 151 is by means of a pivot pin 156 with the console 143 hinge-linked. Also in this version crossed in the form of a pull or push rod designed auxiliary link 146 the handlebars of the lifting gear. The lower end of the auxiliary link 146 also forms a slot 148 out, in which the console-side pin 149 dips. The operation of this second hinge fitting corresponds to that of the previous embodiment.

40 a plan view according to the viewing direction XXXX 35 , without hinged support and push-pull slide.

According to the 26 to 34 the first embodiment will be explained in more detail. Essentially, the hinge fitting exists 170 from a hinge carrier 171 , a lifting member 172 a handlebar 173 , a control lever 174 and a console 175 , wherein the four last mentioned parts together form a four-bar linkage. At the console 175 is a power storage 176 and a holding device 177 arranged.

On the hinge carrier 171 the front flap of a passenger car, not shown here, is attached. The console 175 is struck on the body.

The hinge carrier 171 has a pivot point on its underside 178 for an end of a rope 179 on. The other end of the rope 179 is at a point of articulation 180 who is at the console 175 located, fastened. At the right in the figures part of the hinge carrier 171 this one has a fulcrum 181 on. Below the pivot 181 (please refer 31 ) forms the hinge carrier 171 a controlling body 182 out. The controlling body 182 is designed like a finger and forms on its underside a control curve 183 out.

The driver 173 has an elongated shape. The one end of the handlebar 173 is at the common fulcrum 181 with the hinge carrier 171 drehbe weglich connected. Approximately in the middle of its longitudinal extent forms the handlebars 173 a fulcrum 184 out. At the common fulcrum 184 this is one end of the lifting member 172 hinged. At the other end of the handlebar forms another pivot point 185 from where the control lever 174 is articulated. The driver 173 forms laterally, above the fulcrum 184 , a locking shoulder 186 out. The lock shoulder 186 is from an angled tongue of the handlebar 173 educated. In 26 you can see that the handlebars 173 at its lower end, at which also the common fulcrum 185 lies, a small extension 187 formed.

The lifting member 172 is at the common fulcrum 184 with the handlebar 173 and at another pivot 188 at the console 175 hinged. As in 31 can be seen forms the lifting member 172 one side to the hinge carrier 171 open recess 189 out. The recess 189 forms a semicircular niche 190 with a floor 191 out.

The control lever 174 is with its one end at the common fulcrum 185 with the handlebar 173 connected. The control lever 174 forms a fulcrum 192 together with the console 175 out. With the fulcrum 192 is the control lever 174 articulated with the console 175 connected. Starting from the pivot 192 forms the control lever 174 a first long arm 196 and a second short arm 193 out. At his second arm 193 forms the control lever 174 a stop 194 out. The stop 194 is formed by an angularly bent portion. End of the second arm 193 forms the control lever 174 a catch 195 out. The first arm 196 of the control lever 147 is at an obtuse angle to the second arm 193 ,

The console 175 also forms the fulcrum 188 for the lifting member 172 and the pivot point 192 for the control lever 174 out. As in the 26 and 31 can be seen forms the console 175 on the left a counter-attack 197 out.

The counter-attack 197 is formed for example by a plastic element that on the console 175 with a detent spring 198 is fixed together. The counter-attack 197 lies in a fixation section 199 the detent spring 198 one. Between the pivot points 180 . 192 forms the console 175 a storage cavity 200 out. The storage cavity 200 has an opening to the right 201 on, which has a smaller width than the diameter of the storage cavity 200 has.

At the right side of the console 175 is the holding device 177 arranged. The holding device 177 is from a pawl 202 educated. The pawl 202 is about a pivot 203 stored. It forms a pawl 204 out. The pawl 202 also forms a trigger arm 205 and forms together with this approximately the contour of the capital letter "V". The pawl 202 forms an extension 206 out. At the extension 206 grab a thigh 207 ' a leg turn spring 207 at. The other thigh 207 '' grabs the console 175 at. The thigh torsion spring 207 is around the pivot 203 the console 175 arranged. This acts on the holding device 177 counterclockwise, that is in the reverse direction.

As in 26 is visible below the small appendage 187 of the handlebar 173 a retaining spring 208 arranged. The retaining spring 208 is formed by a resilient element, which is made for example of rubber. By the retaining spring 208 becomes the handlebar 173 with the lock shoulder 186 against the pawl 204 applied. She seems dangling and holding.

The energy storage 176 is designed here in the form of a pyrotechnic element. This forms laterally at its lower end projecting axle extensions 209 out. The axle processes 209 have an almost cylindrical shape. As in 27 good to see is part of the axle process 209 For example, have been milled. He receives thereby a nearly crescent shape. This sectional reduction tion of the cross section of the axle extensions 209 is necessary, so that the axle processes 209 bayonet-like through the opening 201 in the storage cave 200 can be introduced. The other end of the energy store 176 has a tee 210 on. The tee 210 lies in the recess 189 and is the shape of the niche 190 customized. At the bottom of the energy storage 176 protrude two connection cables 211 from. The connection cables 211 can through an opening 212 that are in the console 175 is to be connected.

The following mode of action of the first of the two exemplary embodiments described last occurs:
The 26 sets the normal use position of the hinge fitting 170 how it is installed in the passenger car and then painted with this. By installing the hinge fitting 170 Before the painting process it is ensured that the front flap can be opened and closed. After the painting process has finished, as in 27 illustrates the energy storage 176 in the storage lair 200 used. Only in the 27 illustrated position of the axle extensions 209 is it possible this through the opening 201 in the storage lair 200 use. In a slightly pivoted position of the energy storage 176 it is no longer possible that the axle extensions 209 from the storage cavity 200 can step out. The connection between the console 175 and the energy storage 176 is a kind of bayonet catch. After the energy storage 176 so far has been pivoted that the tee 210 in the recess 189 then, as in 29 the front hood and hinge carrier 171 getting closed.

Now the hinge fitting is located 170 in normal use position. This is the T-piece 210 on the trigger arm 205 the pawl 202 at. But he has a distance to the ground 191 the niche 190 , The pawl 204 the pawl 202 overrides the blocking shoulder 186 of the handlebar 173 , The pawl 202 is due to the force of the torsion spring 207 held in the locked position. As in 26 can be seen, presses the small extension 178 of the handlebar 173 on the retaining spring 208 , This ensures that the locking shoulder 186 against the pawl 204 is charged.

Through an accident with a passerby, the sensors become the energy storage 176 trigger. By triggering the energy storage 176 will, as in 30 Illustrates, first, the tee 210 against the trigger arm 205 the pawl 202 relocated. It first shifts the trigger arm 205 until it reaches the bottom 191 the niche 190 has reached. Against the return spring 207 becomes the pawl 202 relocated.

In 30 is the energy storage 176 extended so far that the pawl 204 the lock shoulder 186 releases. This is done against the force of the leg torsion spring 207 , After the holding device 177 is in its release position, the energy storage 176 completely the hinge fitting 170 shift to the stroke position. For this purpose, the T-piece of the energy storage shifts 176 into the niche 190 into it and impinge on the ground 191 , By the acceleration of the energy storage 176 the hinge carrier shifts 171 very fast upwards. Due to inertia, he moves a little further up after the energy storage 176 has reached its end position, up to the position that in 31 is shown.

In 31 lies the tee 210 at the bottom of the recess 189 at. The stroke end position is from striking the stop 194 who is at the joystick 174 is located, against the counter-attack 197 limited. The hinge fitting 170 is in the stroke end position by the detent spring 198 held. The detent spring 198 oversees the catch nose 195 of the second arm 193 of the control lever 174 ( 31 ).

To the hinge fitting 170 to relocate back to the starting position, the front flap, attached to the hinge carrier 171 is attached, open. By pivoting the hinge carrier 171 becomes the catch between the detent spring 198 and the control lever 174 canceled. The hinge carrier 171 becomes the pivot point 181 pivoted. Because the hinge carrier 171 with the console 175 through a rope 179 is connected by pivoting the hinge carrier 171 the fulcrum 181 around the point of articulation 178 turned clockwise. As a result, the other hinge parts shift in the direction of the starting position.

As in 33 can be seen occurs during pivoting of the hinge carrier 171 the control curve 183 of the controller 182 against the tee 210 of the energy store 76 to return the energy storage to its original position. The position between the hinge carrier 171 and the console 175 gets through the rope 179 maintained. This also makes it possible to use the hinge carrier 171 around the point of articulation 178 to turn.

As in 34 can be seen became the hinge bearer 171 pivoted so far that the energy storage 176 has been completely shifted back to its original position. He's moved back so far that the pawl 204 the lock shoulder 186 can overflow.

By emergence of the Sperrschulter 186 on the tax slope 213 the pawl 202 becomes the pawl 202 against the force of the torsion spring 207 moved back. After complete oversteer of the control slope 213 shifts the leg turn spring 207 the pawl 202 back to its original position and thus locks the hinge fitting 170 , Now it is possible the hinge fitting 170 to reuse. It only needs the energy storage 176 be replaced because the pyrotechnic charge has been used up.

Based on 35 to 38 the second embodiment will be explained in more detail. The reference numerals of the first embodiment will continue to be used for like parts.

Essentially, the hinge fitting exists 170 from the same parts as in the embodiment before. In this embodiment, the control member 182 from a push-pull valve 214 educated. The backpressure slider 214 is below the pivot point 181 at a pivot point 215 hinged. The push-back slider 214 forms at the fulcrum 215 Far end of a curved slot 216 out. Through the arcuate slot 216 sticks out the blocking shoulder 186 therethrough. In this area must be the blocking shoulder 186 have a cylindrical portion.

The energy storage 176 is not as in the first embodiment bayonet with the console 175 connected. This one is with an axis 217 at the console 175 attached. In this embodiment is not illustrated how the handlebar 173 is spring-loaded in its normal use position. It is of course conceivable that this can be done as in the embodiment described above. Here, the fixation of the hinge fitting in the lifting position is not shown. It is conceivable to make this as in the embodiment described above. It is also conceivable here, the energy storage 176 with a kind of quick release at its lower end to verse hen.

In the second embodiment, the following mode of action arises:
In 35 is the hinge fitting 170 in normal use position. As in the embodiment described above, first the trigger arm 205 from the tee 210 of the energy store 176 applied. Because of the pawl 202 against the force of the torsion spring 207 shifts and gives the lock shoulder 186 free. Now apply the tee 210 the ground 191 the niche 190 and shifts the hinge fitting 170 in the stroke end position; this one is in 36 to see.

By pivoting the hinge carrier 171 around the fulcrum 181 becomes the hinge fitting 170 moved back to its starting position. Here too this is done by a rope 179 reached. When shifting back the hinge fitting 170 pushes, as in 37 you can see the push-pull valve 214 cam controlled against the tee 210 of the energy store 176 , By further pivoting the hinge carrier 171 becomes the energy storage 176 completely shifted back to its original position and the locking shoulder 186 gets back from the pawl 204 the pawl 202 flashed. Here are the lock shoulder 186 assigned to two tasks, on the one hand, the hinge fitting 170 in its initial position on the holding device 177 to tie and on the other hand the Rückdrückschieber 214 to control.

It is also provided here, a quick release for the energy storage 176 because it is then possible to easily exchange it. It is also advantageous if, as in the first embodiment, a retaining spring 208 in normal use position on the handlebar 173 acts. This measure ensures that there is vibration of the hinge fitting 170 to no noise comes. This is a rattle lock. It is also advantageous, as in the first embodiment, the hinge fitting 170 in the stroke end position by a detent spring 198 to fix.
