Definitions
- the invention relates to a sensor circuit, which is particularly suitable for motor vehicles, preferably for seat occupancy detection and / or child seat detection, and to a circuit carrier designed for this purpose.
- a sensor circuit for seat occupancy detection for a motor vehicle seat which has a sensor mat designed as a film. If the seat is occupied, the internal electrical resistance of the sensor mat changes due to the load, which is recognized by an external circuit.
- DE 44 09 971 C2 discloses a sensor circuit for recognizing a seat occupancy by means of a child seat, in which the sensor mat arranged in the seat has a base antenna for recognizing the presence of a child seat on the basis of a characteristic influence on the measurement field generated by the base antenna.
- the output signal emitted by the sensor circuit and representing the seat occupancy state is sent to a control device which controls the airbag trigger in an emergency.
- Sensor information enables controlled inflation of the front passenger airbag depending on the position of the occupant or child seat.
- the evaluation and control electronics are also integrated in the vehicle seat and are, for example, electrically connected via a cable harness to a control device for airbag triggering which is arranged at another point in the vehicle.
- the electronics in the vehicle seat are designed as a circuit on a conventional, rigid printed circuit board is encapsulated with plastic and has soldered-in connecting pins for the connector and sensor connection.
- the mating connector of the wiring harness must be inserted into the connector of the electronic circuit installed in the vehicle seat. This insertion process takes place due to the arrangement of the connector on the electronic circuit in the lower area of the vehicle seat and is therefore not only bulky, but also time-consuming and error-prone.
- the invention has for its object to provide a sensor circuit that is characterized by simple design and manageability.
- Circuit carrier created, which is suitable for use in such a sensor circuit.
- the circuit carrier is thus implemented using film technology and forms a flexible or rigid-flexible (semi-flexible) printed circuit board, which can be formed, for example, from polyimide or polyester with conductor track structures made from copper tracks or silver conducting towers.
- the circuit carrier is in particular designed in such a way that it is provided with an integrated, that is to say integrally formed, cable tail.
- the distance between the connector plug attached to the end of the cable tail to the electronic control unit, for example for airbag control, and the electronic circuit located on the circuit carrier is greatly increased, so that, for example, the cable tail is mounted despite the inaccessible or only cumbersome electronic circuit (circuit carrier) can be positioned in a more accessible place, for example under the vehicle seat. This will make the Much easier to insert.
- the cable tail is formed directly by part of the flexible circuit carrier, it forms an integrated extension piece which, due to its integral design, does not make any separate electrical contact with the circuit carrier.
- the cable tail can be formed by an essentially U-shaped extension of the printed circuit board. Due to the flexibility, the free leg of the U-shaped section can be brought to the desired location. Preferably, the cable tail can also be folded, so that the total length of the cable tail compared to the individual
- Leg length of the U-shaped section can be substantially doubled.
- a recess with a particularly circular design can be provided in the transition area between the two legs of the U-shaped section.
- the circuit carrier and the cable tail can be integrated on this film sensor, that is to say the film sensor itself is simultaneously used as the circuit carrier and the cable tail.
- the film sensor thus has a dual function as a sensor mat and circuit carrier and at the same time also forms the cable tail. stucco. This means that the sensor connection by means of plugged or soldered contact connections can be dispensed with, so that fewer interfaces result and higher contact reliability is achieved. Fewer mechanical components are also required because, for example, crimp connectors are partially or completely eliminated and a separate cable is also replaced by the cable tail.
- the solution according to the invention is thus also more cost-effective than previous solutions.
- the electronics that is to say the electronic circuit located on the circuit carrier, can be folded before being embedded in a potting material, so that the resulting circuit has a very small size.
- a very high level of integration of the circuit on the circuit carrier can also be achieved, so that compact dimensions are achieved.
- the SMD components can also be applied by gluing using conductive adhesive, so that simultaneous mechanical and electrical contacting is ensured. This enables the circuit carrier to be constructed quickly and inexpensively.
- the entire electronics unit is preferably surrounded by a potting material, for example overmoulded by means of an overmould material such as macromelt. This eliminates the risk of undesirable damage to the electronic components. No additional manipulation protection is required because of this encapsulation, and a high protection class can be achieved.
- the cable tail is preferably surrounded by a flexible material, for example encapsulated by means of a thermoplastic material, so that it is mechanically protected and still maintains sufficient flexibility.
- the circuit carrier is not designed to be integrated on the film sensor, that is to say is connected to it in one piece, it is necessary to connect the circuit carrier to the film sensor, which in this case may not have to contain a cable tail arranged in one piece, which is the case, for example can be achieved by foil-foil crimp connection or by heat-seal connector.
- the present invention preferably also offers a simple possibility of connecting different film sensors, which differ in different contact assignment, to the same electronic circuit located on the circuit carrier without the use of adapters being necessary.
- the electrical contact connecting piece of the circuit carrier used for contacting the film sensor is not formed in one piece, but is designed in the form of at least two tongues which carry the electrical connecting contacts and are movable independently of one another.
- the tongues are separated, for example, by incisions or material punchings between them. Due to the flexibility of the circuit carrier, this enables a separate folding and / or folding over of individual tongues in such a way that the spatial arrangement of the electrical connection lines in the connection field achieved after the folding or folding over of the tongues is brought into line with that of the film sensor to be contacted.
- the connection area of the circuit carrier can thus be easily adapted to the respective pin assignment of different film sensors without the need for separate adapters. This drastically reduces the effort required for wiring with different film sensors.
- the invention also creates a flexible circuit carrier which has the features explained above individually or in combination, that is to say in particular is provided with an integrally formed cable tail and preferably additionally has tongue-shaped connection areas for contacting an electrical component, for Example with the sensor mat or with a differently constructed sensor element or other electrical component contains.
- the sensor circuit according to the invention is designed in particular for use in a vehicle seat for seat occupancy detection, the sensor signals preferably being used to control an airbag (smart airbag), but also for other purposes, for example for automatically extending head restraints when seat occupancy is detected . It is also possible to use the sensor circuit to record other parameters.
- FSR force sensing resistor
- the invention consequently creates the possibility of an integrated interface electronics for a seat occupancy detection or a child seat detection with a direct connection to a film pressure sensor film and connection to an electronic control unit ECU, that is to say is preferably a component of such a passenger protection system and is preferably in the motor vehicle seat built-in.

- a circuit carrier section 1 which is encircled all around in the manner shown by a potting material, for example “macromelt”, and is thereby protected against damage, contact, moisture influence, etc.
- the protective cover 3 can, as shown in FIG. 1, contain lateral transverse recesses 4 and top and bottom recesses 5, as shown in the drawing. This ensures high flexibility of the cable tail 2 and still ensures adequate protective function.
- the recesses 4 and cutouts 5 lead to a reduction in the protective sheath weight, so that the weight-related deflection of the cable tail 2 is reduced.
- the free end of the cable tail 2, which is not connected to the circuit carrier section 1, is connected to a plug 6 completed, which enables connection to an electronic control unit located in the vehicle by means of a correspondingly designed mating connector.
- the circuit carrier section 1 is provided by soldering, crimping, fusion bonding or preferably also in one piece with a connection 7 in the form of a film connection which is led out on a side face of the casting block surrounding the circuit carrier section 1.
- This connection 7 enables connection to a film sensor (sensor mat), not shown, which is to be installed in the vehicle seat.
- the components, not shown, attached to the circuit carrier section 1 can be represented as SMD components which generate the driver signals for controlling the film sensor and / or convert and / or evaluate the sensor signals emitted / influenced by the sensor film.
- the signals are then forwarded via the cable tail 2 to the control unit located in the motor vehicle.
- circuit carrier 8 is shown without potting material, protective cover 3, connector 6 and connector 7, that is, shown in the state that it after cutting the flexible circuit board and before the assembly with the
- the circuit carrier 8 is designed in film technology as a flexible or rigid-flexible printed circuit board and consists, for example, of polyimide or polyester with a conductor track structure which is formed by copper tracks or silver conductive ink.
- the circuit carrier section 1 is equipped by means of soldered or glued SMD components.
- the cable tail 2 is formed in one piece with the circuit carrier section 1, that is consists of the same flexible printed circuit board as section 1.
- the U-shaped shape of the cable tail 2 leads to a relatively large overall length of the cable tail 2 with a small amount of waste of the printed circuit board used to manufacture the circuit carrier. All parts of the cable tail 2 are consequently in the same plane as the circuit carrier section 1, but can be bent out of this plane due to the flexibility of the cable tail and brought into a desired position. Since the connector 1 shown in FIG. 1 is attached directly to the end of the cable tail, it is directly via the conductor tracks of the cable tail 2, without further interface, with the conductor tracks on the circuit carrier section 1 and the components attached to it m electrical contact.
- FIG. 3 shows a further exemplary embodiment of a circuit carrier 9, which has a circuit carrier section 10 for receiving the electronic circuit components and a cable tail 11 formed in one piece with it.
- the cable tail 11 consists of two U-shaped arrangement
- Legs 12, 14, which are integrally connected to one another via a crosspiece, which is provided on the side of the leg facing away from the circuit carrier section 10 and which connects the electrical connection lines present on or in the cable tail 11 without interruption from the circuit carrier section 10 to the free end of the leg 14.
- the legs 12, 14 are provided in their mutual connection area with a circular recess 13, which is formed when the flexible printed circuit board is punched and prevents the cable tail 11 from tearing when it is deformed, for example when the leg 14 is folded over.
- the circuit carrier section 10 is provided with a connection area 15, to which the electrical contacts for contacting are arranged with the sensor mat.
- the attachment area 15 is divided into at least two, preferably three tongues 16, 17, 18, which are separated from one another by incisions 19 and can thus be bent / folded independently of one another.
- the incisions 19 are cut sufficiently deep and extend, for example, to the extension of that side edge of the circuit carrier section 10 from which the tongues 16 to 18 extend.
- the contacts formed on the tongues 16 to 18 are connected without interruption via continuous conductor tracks to the corresponding mounting points of the electrical components to be applied to the circuit carrier section 10.
- FIG. 4 shows the circuit carrier shown in FIG. 3 with an integrated cable tail upside down, the leg 14 being folded outwards.
- the axial length of the cable tail 11 is almost doubled.
- the kink of the folding of the cable tail lies in the region of the recess 13.
- FIG. 5 shows the circuit carrier 9 shown in FIG. 4 after the leg 14 has been folded over again, now about the longitudinal axis, in such a way that the axial course of the leg 14 is aligned with that of the leg 12.
- Fig. 5 it can also be seen that the tongues 16, 17, 18 are folded over such that the position of the connecting pins of the tongues 16 and 17 are reversed.
- the folding of the tongues is carried out such that the order the sequence of the individual connection contacts (pins) in the individual tongues 16 and 17 is unchanged, that is, the tongues 16 and 17 are not turned.
- the tongue 16 is first folded up about a folding axis running at an angle of 45 ° to the longitudinal axis and this folded part is then folded outwards again about an axis lying parallel to the first folding axis.
- the tongue 17 is folded down in a similar manner.
- the tongue 18 is folded only twice transversely to its longitudinal axis, so that the connection pins in the tongue 18 maintain their spatial position and only the distance to the circuit carrier section 10 is shortened in the same way as that of the tongues 16 and 17.
- the terminal end faces of the tongues 16, 17 and 18 are therefore at the same height, that is to say they are aligned with one another.
- This folding technique makes it possible to change the spatial sequence of the contacts of the tongues 16, 17 and 18 in the desired manner and to adapt them to different contact assignments from different sensor mats, for example from different manufacturers. A simple interchanging of connections can thus be achieved.
- One or more line connections can be provided for each tongue.
- a crossing of the connecting lines which may be necessary depending on the arrangement of the electronics relative to the sensor film or depending on the pin assignment of the sensor film, can thus be achieved by simple folding, without any other electrical measures or the need for an adapter.
- FIG. 6 shows the circuit carrier 9 shown in FIG. 5 with an additional, flexible sheathing 20 of the cable Tail 11 and at its free end attached plug 21.
- the casing 20 may correspond to the protective cover 3 shown in FIG. 1 in terms of material and shape. The same also applies to the plug 21, which corresponds to the plug 6 shown in FIG. 1.
- the circuit carrier is shown here in the not yet populated and encapsulated state.
- FIG. 7 the circuit carrier according to FIG. 6 is shown in an inverted representation with an additional casting block 22 and sensor connection 23.
- the casting block 22 encloses the
- Circuit carrier section 10 on all sides, only the cable tail 11 with sheathing 20 and the sensor connection 23 protruding laterally from it on two adjacent sides.
- the potting block 22 can also enclose a small part of the U-jacket 20 so that it is firmly embedded in the potting block.
- the sensor connection 23, which serves for connection to the sensor mat, is electrically conductively connected within the casting block 22 to the line connections of the folded tongues 16, 17 and 18, e.g. by soldering or fusing (heat seal connection), these contact points being protected by the casting block 22 as well as the electrical components located on the circuit carrier section 10.
- the folding area of the cable tail 11 is symbolized by a circle 24.
- This folding area is additionally mechanically fixed and protected by the thermoplastic sheathing 20, so that the electrical reliability of the cable tail is not impaired by the cable tail folding.
- FIG. 8 an enlarged view of the not yet encapsulated circuit carrier section 10 with folded-over connecting tongues 16, 17 and 18 is shown in a top view (FIG. 8) and m view from below (FIG. 9).
- the tongue 16 is hatched. It can be seen that the connecting tongues are folded to the same length.
- the height offset, which arises due to the different folding direction of the tongues 16, 17 and 18, is extremely small and can be easily compensated for by the flexibility of the circuit carrier.
