Description

The The invention relates to a device for holding an attachment in a vehicle, such as a light housing or a fuse box, on a vehicle seat, wherein the Holding device on the one hand a captive for fastening on the attachment and on the other hand latching means for holding on the vehicle seat having.

such Holding devices, by means of which attachments to a vehicle fast and reliable on a suitable receptacle on the vehicle can be mounted or clicked, in particular Well known in the field of vehicle construction, and have varied in everyday use proven.

A generic fastening device is for example from the patent DE 30 44 313 C2 in which a fastening device is described for components received in depressions of body parts. The fastening device disclosed therein comprises, in particular, a spring region which can deflect into a suitable body opening in order to be able to support and fasten the component to the body part or to the body recess there. The fastening device takes on pressure forces between the body part and the component, so that the component can be securely arranged on the body molding. In order for the fastening device itself to be securely attached to the component, it has barbs at an end lying opposite the spring region, which barbs can hook into the component when the fastening device is inserted into a suitable opening of the component. By means of the barbs fastening device is permanently connected to the component, that is, that the fastening device can be removed from the component only by destroying this opening.

It Object of the present invention, such fastening devices structurally to develop, in particular assembly work of attaching parts to a vehicle or parts thereof faster and easier to do.

The The object of the invention is a device for holding a Attachment of a vehicle, such as a light housing or a fuse box, solved at a vehicle seat, wherein the holding device on the one hand a captive to Attach to the attachment and on the other hand locking means to hold at the vehicle seat, and wherein the holding device characterized by a pressure arm on which the captive is arranged.

Of the Term "pressure arm" herein describes any facilities by means of which compressive forces and thereby especially also bending forces can be absorbed, so that by means of the pressure arm in the field of captive also a bending spring can be realized, by means of which the holding device can be secured captive on an attachment. insofar The pressure arm can also be a bending arm or a pressure-bending arm the holding device act.

Consequently the holding device is simple on the one hand, in particular also automated, attachable to the attachment and on the other hand can attachment side structurally simple a suitable Druckarmaufnahme be designed in which the pressure arm is clamped quickly and easily accessible can be. The holding device according to the invention has the advantage that a release of the bracket also at great vibrations, such as in a vehicle occur, is excluded. In addition, you can According to the invention unterschliedlich designed Holding devices are used.

Of the Term "attachment" covers any components, component groups or body parts of a vehicle, which to a for Provided location permanently attached to the vehicle and reliable shall be. In particular, these may be luminaire housings, such as a headlight housing of a motor vehicle, act quickly and reliably without much effort should be mounted or dismantled.

at the "captive" described here is to a device by means of which the holding device such attachable to an attachment that the holding device is not can get lost.

A preferred embodiment provides that the holding device includes a detachable captive. This can be a attached to an attachment holding device advantageously be detached from the attachment destructive. This is for example advantageous if a defective attachment must be replaced. In such a case, the holding device easily and quickly removed from the defective attachment and just as easily and quickly mounted to the replacement component and thus used advantageously again. Also, an existing one Holding device by a stronger or different Replaced fixture without much work become.

A captive, in particular a detachable captive, can be made structurally simple and particularly cost-effective, if the captive, in particular the detachable captive, a tensionable spiral spring, in particular a leaf spring comprises. Advantageously, a suitable bending or leaf spring can be provided by means of the pressure arm explained above, since these compressive forces and advantageously also can absorb bending forces.

Around the latching means spaced from the captive securing the holding device to be able to provide at a designated rest stop, It is also advantageous if the holding device is a support arm has, on which the locking means are arranged.

The Locking means can engage particularly easily at the latching point, if the support arm is another tensionable spiral spring, in particular a leaf spring, the holding device comprises. This can be a Preload of the bending spring a reliable locking of the locking means increase.

includes the holding device both a captive and a Support arm for locking means, which designed as a spiral spring are, it succeeds in an advantageous manner, the holding device structurally very compact design.

Also if the support arm in the present case can be designed as a bending spring, the arm is not intended to all Bearing pressure forces between the attachment and for example to pick up a vehicle body and transfer it between you. A mechanical support is done in the present Not only about the spring-loaded design described here Retaining spring, but on other connector devices between the attachment and a related attachment recording.

Of the Support arm of the holding device is accordingly in the first place intended for unintentional release, for example to prevent one or more connectors, so that the Attachment reliable on the intended attachment mounting remains and a mechanical support of the attachment is permanently ensured by means of the connectors.

insofar For example, the support arm or at least a portion thereof may be used this last described function as a pulling arm of the holding device to be discribed. The term "pulling arm" describes one Area of the holding device, which essentially only tensile forces absorbs and transmits. In particular, it succeeds thereby being able to build the holding device more filigree.

It It is understood that the locking means performed manifold could be. For example, locking means Include push-in lugs, in which suitable latching hooks engage can. With regard to the mounting of an attachment to a For this purpose provided vehicle seat, an assembly particularly easy and fast if the locking means include a latch.

A Such locking lug is particularly easy to produce, if, for example is formed by a curved support arm.

Especially if the holding device is made of metal, it is advantageous when the support arm is double-walled in the region of the latching means is to bring more stability in the holding device. For example, a leaf spring is bent such that the leaf spring Double-walled in the region of the locking lug. It It should be mentioned at this point that the holding device may also consist of plastic or a mixture, for. B. could also a glass fiber reinforced plastic are used.

has the support arm beyond an actuator on, can a once latched locking lug of the holding device Easier unloaded and an attachment from a vehicle seat be removed. This can be, for example Shorten service times.

One attached to a suitable vehicle mount attachment can on the vehicle seat are held particularly well when the arm a Butt area, in particular a plug connection, of the attachment and the vehicle receiving overhangs. This means that the arm of the attachment over the joint area, on which the attachment and for example a vehicle body abut each other until it extends to the vehicle seat.

A Particularly preferred embodiment provides that the holding device has a positioning web, which is the Attachment, in particular an attachment housing, pass through can. By means of the positioning web of the holding device succeeds it in a structurally particularly simple way, the holding device a designated place on an attachment safely and thus to place quickly, especially if the positioning bar can penetrate the component.

It is also conceivable to equip the positioning web with locking means, for example with resilient projections, which cooperate with counter-locking means of the attachment housing, for example in the form of defined breakthroughs, positively and / or non-positively. Thus, the locking means and Counter-locking means for the positioning web z. B. form a clip connection.

optional the positioning web can be L-shaped, wherein in this case at least a part of a positioning web Anbauteilgehäuses structurally simple can be embraced.

at an arrangement of the positioning web between the pressure arm and the support arm, the holding device is particularly simple, because of the positioning web a separation between captive area and Rastmittelbereich the holding device structurally advantageous succeed.

If at a first end of the support arm, the locking means and at another End of the support arm of the positioning web are arranged, the holding device structurally simple with their support arm even bigger easily overtop trained impact areas.

Around Such a shock region, in particular a plug connection, between the attachment and the vehicle seat particularly well mechanically To hold together, it is advantageous if the Support arm is bent, so that the support arm the impact area or the connector between the attachment and the vehicle seat excluded. Hereby can also in a simple way Manufacturing tolerances are compensated.

So provides a further advantageous embodiment, that the support arm together with the locking means and the positioning web a bracket of the holding device is formed, by means of which a joint area or a connector advantageously held together or together can be stapled.

The Holding device can be structurally kept very slim, when the support arm and the pressure arm so on the holding device are provided that they are arranged opposite to each other. In this case, the support arm, starting from the positioning web, and the pressure arm, also starting from the Positioniersteg, contrary set to be aligned with the holding device and run.

Around Druckarmseitig a previously described bending spring of the captive To be able to realize it is advantageous if the pressure arm the holding device at its free end or at its the support arm curved away from the opposite end. By the curvature can, with appropriate clamping of the pressure arm, within the pressure arm structurally very easy to build a voltage. This is For example, the case when the positioning bar on the attachment stored and the arm facing away from the end of the pressure arm also is stored on the attachment, and a distance between the two Bearing points is less than the length of the placed there Pressure arm.

The present holding device only needs little holding or Securing forces, in particular in the region of the support arm, can accommodate when the holding device spaced is arranged by fixing pins, which on the attachment, in particular are molded onto the attachment housing. The fixing pins serve to maintain main forces between the attachment and to receive a vehicle seat, so that the present holding device to absorb only slight holding or securing forces has, as already described above.

It is understood that the present holding device diverse can be designed. In particular, for the realization the holding device different materials are used. A particularly robust embodiment, however, provides that the holding device is a retaining spring made of metal. Such Metal retaining spring can be as cost-effective bending part about made of a strip material and / or a wire material become. Especially with metal retaining springs remains a spring force largely constant in terms of time and in terms of occurring Temperature differences. When a metal retaining spring with a vehicle-side Rastbereich interacts, it is advantageous if the metal retaining spring a coated surface or made of stainless steel is to prevent premature corrosion can.

The The object of the invention is also of an attachment, in particular a luminaire housing, with pins for fixing the attachment solved on a receptacle of a vehicle, wherein the attachment, in particular the attachment housing, through a holding device characterized according to one of the features explained above. Is an attachment equipped with such a holding device, It may advantageously be final assembled faster because, for example an attachment of the holding device to the attachment already at Manufacturer of the attachment can be made, and so equipped Attachment during final assembly, for example by an automaker, can simply be clicked into the intended vehicle seat. The Final assembly may also be due to the retaining spring described herein be automated, for example by means of a mounting robot, so that the assembly of the attachment can be done even faster.

Based In the accompanying drawings, the invention will be described below explained in more detail.

there shows:

1 schematically a side view of a holding device, which is designed as a metal holding spring,

2 schematically a view of a motor vehicle headlamp with a housing on which the holding device of the 1 is arranged captive,

3 schematically a detailed view of the connector from the 2 .

5 schematically an assembly process of the holding device to the housing from the 2 to 4 , and

6 schematically an assembly process of the housing equipped with the holding device of the 2 to 5 to a vehicle body.

The in the 1 shown holding device 1 is exemplary as a metal retaining spring 2 with a captive 3 and detent means 4 educated. In essence, the holding device 1 in a support arm 5 that the catch means 4 includes, and in a pressure arm 6 that's the captive 3 includes, be subdivided. The subdivision into a support arm 5 and in a pressure arm 6 takes place in this embodiment in a separation area 7 a positioning bar 8th which is L-shaped.

While an upper thigh 9 of the positioning bar 8th essentially perpendicular to the pressure arm 6 is arranged, runs a lower leg 10 of the positioning bar 8th essentially parallel to the pressure arm 6 and is on the catch means 4 directed substantially perpendicular to the upper leg 9 of the positioning bar 8th arranged. The positioning bar 8th forms with his two thighs 9 . 10 a positioning area 11 who is to the locking means 4 is open.

The pressure arm 6 is at his the carrying arm 5 opposite free end 12 downwards, so to the positioning bar 8th towards, slightly curved, leaving the free end 12 better in a sink explained below 32 (please refer 2 and 3 ) can intervene. The pressure arm 6 is between the positioning bar 8th and the valley 32 trapped. This can be within the pressure arm 6 a bias voltage can be generated. In this respect, the pressure arm forms 6 a spiral spring 6A the captive 3 ,

The pressure arm 6 in interaction with the positioning bar 8th can thus in a structurally simple way the detachable captive 3 in the holding device 1 represent.

While the pressure arm 6 , starting from the separation area 7 , essentially in a first direction 13 extends, the support arm extends 5 , starting from the separation area 7 , essentially in one of the first directions 13 opposite second direction 14 , The support arm 5 starts from the separation area 7 straight line and then forms a bulbous area 15 until he almost bent in opposite directions into a catch 16 then goes over with an opposite curve in an actuator 17 to end up running into it.

So formed, designed the arm 5 between the positioning bar 8th and the latch 16 a bracket area 18 in which two components can be held together.

So that the catch 16 can snap into place with a bias in a designated resting point advantageous, is the support arm 5 with its described shape as another spiral spring 5A the holding device 1 educated.

The metal retaining spring 2 can be designed as a wire construction. In this embodiment, however, it is made of a strip material, so that the two bending springs 5A and 6A are designed as leaf springs.

In a first embodiment (see 2 ) are two fixtures 1 (only exemplified here) in connection with a motor vehicle headlight 20 shown in a concrete application example.

The motor vehicle headlight 20 includes a luminaire housing 21 , which is front with a cover 22 and behind with a cover 23 is provided. Inside the vehicle headlight 20 you can see a reflector 23 with a light bulb attached to it 24 ,

The luminaire housing 21 points in the area of its cover 22 a circumferential housing collar 26 on, the circumferentially distributed fixing pins 27 (numbered here only by way of example). These fixing pins 27 can in later described in more detail Fixiernuten 35 (see in particular 3 ) of a vehicle body 28 be plugged in, so that the motor vehicle headlight 20 on the vehicle body 28 is securely fixed. About the fixing pins 27 there is a main support of the motor vehicle headlight 20 on the vehicle body 28 such that main forces occurring are mechanically supported by the Fi xierzapfen 27 in the vehicle body 28 be initiated.

The example of the connector 29 in the upper area 30 of the luminaire housing 21 should now be the use of the holding device 1 be explained in more detail. To the holding device 1 captive on the luminaire housing 21 To be able to attach, comprises the circumferential housing collar 26 material recesses 31 into which the positioning bar 8th engage and the luminaire housing 21 can partially embrace. At the same time the pressure arm 6 with its curved end 12 in a valley 32 of the luminaire housing 21 pressed so that the pressure arm 6 between the valley 32 and the material recess 31 , here with the help of the positioning bar 8th , clamped and thus the holding device 1 captive on the luminaire housing 21 is attached.

The support arm 5 overhangs the plug connection 29 , especially in a joint area 33 in which the luminaire housing 21 to the vehicle body 28 abuts, embraces with the support arm 5 worn locking means 4 the suitably formed vehicle body 28 so that the latch 16 the vehicle body 28 can engage.

So assembled, the luminaire housing 21 always to the vehicle body 28 pulled up. In this connection one can with the support arm 5 also by a pulling arm of the holding device 1 speak, because by means of the support arm 5 essentially no or only negligible support forces between the lamp housing 21 and the vehicle body 28 be transmitted. Such support forces are exclusively on the fixing pins 27 of the luminaire housing 21 and the vehicle body 28 transfer.

To the plug connection 29 be able to solve again later, a gripping the actuator suffices 17 , by means of which the spiral spring 5A and the locking means 4 can be bent so that the latch 16 over the vehicle body 28 can be relocated.

The function of the connector described here 29 is on the other connectors 34 between the luminaire housing 21 and the vehicle body 28 transferable.

The plug connection 29 is in the 3 and 4 shown again in detail. Next to the holding device 1 on the one hand recognizes the encircling housing collar 26 with its fixing pin 27 , with its material recess 31 and its sink 32 as essential features for realizing the connector 29 , So that the fixing pin 27 not unlimited in the fixing groove 35 on the vehicle body 28 is plugged in, behind the fixing pin 27 a fixing stop 36 on the surrounding housing collar 26 molded.

So that the catch 16 the holding device well on the vehicle body 28 can engage, includes the vehicle body 28 a locking edge 37 , which of the catch 16 the holding device 1 , in particular as regards the 2 shown, can embrace.

Like now the holding device 1 captive on the luminaire housing 21 is attached is schematically in an assembly sequence shown 40 of the 5 shown.

In a first assembly step 41 the holding device 1 , for example, as a metal spring 2 is shown, the top from the arrow direction 42 on the surrounding housing collar 26 introduced. Of course, the described assembly of the holding device 1 not from the material of the fixture 1 dependent.

In a second assembly step 43 the positioning bar emerges 8th in the material recess 31 on, while the pressure arm 6 with his free end 12 on a sink heel 45 the valley 32 rests.

In a third assembly step 44 becomes the holding device 1 in the direction of the arrow 42 down to a circumferential housing collar 26 pressed, with the L-shaped positioning web 8th completely in the material recess 31 protrudes and with the lower leg 10 from below from the material recess 31 protrudes.

The metal retaining spring 2 is then in a final assembly step 46 in the direction 47 on the fixing pin 27 too moved, leaving part of the encircling housing collar 26 in the positioning area 11 of the positioning bar 8th passes and the pressure arm 6 himself with his curved free end 12 with a lowering movement 48 into the valley 32 moved into it. At the same time, the holding device 1 with the L-shaped positioning bar 8th , in particular with its upper and lower legs 9 . 10 , positive fit in the positioning area 11 held on the attachment housing, whereby a total of the claimed captive 3 is realized.

Subsequently, the luminaire housing 21 according to the in 6 Luminaire housing assembly process shown in more detail 50 to the vehicle body 28 assembled.

For this purpose, the luminaire housing 21 with the metal holding spring attached to it now captive 2 with an assembly movement 51 on the vehicle body 28 too moved, with the luminaire housing 21 so opposite the vehicle body 28 aligned, which is the fixing pin 27 and the fixing groove 35 are opposite.

In the course of the assembly movement 51 pushes the metal retaining spring 2 first with their actuator 17 to the vehicle body 28 and is here according to a lifting movement 52 opposite the vehicle body 28 raised so that the fixing pin 27 until the fixing stop 36 into the fixation groove 35 can be inserted, with the latch 16 the metal retaining spring 2 with a downward movement 53 the locking edge 37 the vehicle body 28 behind grips and the metal retaining spring 2 thus on the vehicle body 28 is engaged.

Locked in such a way, the luminaire housing 21 unintentionally from the vehicle body 28 not deducted.

Good to see is that the main supporting forces between the fixing pin 27 , the fixing groove 35 and the fixing stopper 36 be transferred so that the metal retaining spring 2 in the area of its support arm 5 essentially only with tension forces 54 is loaded from the outside.
