    [0001] The present invention relates to a horn for a steering wheel according to the preamble of claim 1. The invention relates to a horn for a steering wheel according to the preamble of claim 1. The invention relates to a horn for a steering wheel according to the preamble of claim 1. The invention relates to a horn for a steering wheel according to the preamble of claim 1. The invention relates to also a steering wheel equipped with a sounding device of this type, as well as a suitable manufacturing process. A warning device of the type mentioned in the introduction is known for example from patent document EP 0 975 058 B1. The known sounding device comprises a first and a second contact element, said contact elements being made in the form of wires which are held in a cage. The cage comprises zones in which the contact elements are maintained at a defined distance. One of the other and further includes areas in which the first contact element can be elastically deflected in zones and in contact with the second contact element in the deflected position. It is thus possible to close an electric circuit of the buzzer. The known horn device is disposed in an airbag module or is integrated in the airbag module. The airbag module generally comprises a housing for housing an airbag, which is closed by a cover. Said cover is movable relative to the housing, in particular slidably movable, and forms in this sense a control device for deflecting the first contact element. In other words, the known audible warning device is disposed between an airbag housing and the cover. Integrating the horn into the airbag module increases the complexity of the airbag module and reduces the flexibility of configuration thereof. In addition, the audible warning device integrated in the air bag module increases maintenance costs, since to replace the audible warning device, for example as a result of a malfunction, it is also necessary to completely disassemble the cushion module. inflatable. Finally, the audible warning device limits the interior volume of the airbag housing. The object of the invention is to provide a sound horn device for a steering wheel, which can be set up independently of an airbag module. The object of the invention is also to propose a steering wheel equipped with a sounding device of this type, as well as a manufacturing method. This object is solved according to the invention, in terms of the audible warning device by the object of claim 1, in the plane of the steering wheel by the subject of claim 7, and in terms of the manufacturing process The invention is based on the idea of providing an audible warning device for a steering wheel, comprising a first contact element and a second contact element, which are arranged at a distance from each other. from one another in a cage. The first contact element is elastically deformable at least in zones so that the first contact element comes into contact with the second contact element for closing an electric circuit of the buzzer. According to the invention, the cage comprises at least one anchor pin for fixing the audible warning device in a foam padding of the steering wheel. Unlike the known audible warning device, the invention provides for attaching the horn to the steering wheel, specifically in the foam padding of the steering wheel. The audible warning device is thus separated from the airbag module and forms a separate room. This increases the configuration flexibility of the airbag modules and in particular reduces their complexity. It is thus possible, for example, to give up moving parts relative to each other on the airbag module. Since it is possible to integrate the audible warning device into the steering wheel, it is possible to enlarge the airbag module. In this way, it is possible in particular to provide a larger interior volume for the airbag housing, since it is unnecessary to have additional guide elements on the airbag module for the mobile mounting of a lid.
    [0002] In a preferred embodiment of the audible warning device according to the invention, the anchor pin has a hook-shaped tip. As a general rule, the anchor pin can be structured similarly to a hook. In this way, a particularly good fixation is obtained in the foam packing of the steering wheel. In a preferred embodiment of the audible warning device according to the invention, the contact elements are each formed by an electroconductive wire, in particular an electroconductive spring wire, the two contact elements having a three-dimensional bending structure and preferably , being made substantially identically. Therefore, it is possible to follow the contour line or contact line (three-dimensional), projecting on a plane, between the module and the steering wheel, and to arrange the contacts of the buzzer along this line or between the module and the steering wheel, and at the same time arrange the horn module so that it or elements of its cage can be used as a guide element for the module. The control section of the cage may be further disposed between at least two attachment sections. The contact elements are separated from each other in the attachment section, preferably by an electrically insulating separation spacer. The electrically insulating separation spacer prevents undesirable contact between the contact elements and therefore undesired triggering of a buzzer signal. This is usually generated when the electrical circuit of the buzzer is closed. The electric circuit of the buzzer may include a sound generator which transmits an audible signal, in particular a buzzer signal, to a loudspeaker. The cage of the audible warning device according to the invention may comprise, in addition, at least one guide pin, which extends in the opposite direction of the anchor pin. The guide pin can receive guide bushes which are arranged for example on an airbag module. As a result, the guide lugs induce guided relative movement between a control device, for example an airbag module, and the foam lining of the steering wheel. In this sense, the horn can form a positioning device for adjusting an airbag module or a cover of the airbag module with respect to the steering wheel foam lining. Since the audible warning device can be incorporated directly into the foam padding of the steering wheel, it is possible to compensate tolerances of the foam padding, so that a horn slot is uniformly made between, for example, a lid of an airbag module and the foam lining of the steering wheel. In this way, the audible warning device decreases in particular the chain of tolerances which influences in particular the slot of the buzzer. In a preferred embodiment of the audible warning device according to the invention, it is provided that the cage, in the mounted position, extends in a ring along a receiving opening, provided in a steering wheel, for an airbag module, activation projections being provided on the inflatable cushion module such that by lowering the airbag module toward the steering wheel, the first contact element contacts the second element to close the electrical circuit of the buzzer. In another preferred embodiment of the audible warning device according to the invention, it is possible to provide that the contact elements are each formed by an electroconductive wire, in particular an electroconductive spring wire. By the use of a wire, more specifically a spring wire, it is ensured that the first contact element is sufficiently elastic to contact the second contact element. The first contact element is deformable, preferably transversely to its longitudinal extension, so that the deformed portion of the first contact element removes the distance between the first contact element and the second contact element and thus makes an electrical contact. between the two contact elements. On the other hand, spring wires or wires have the advantageous property for the invention of returning substantially automatically to their initial position. The deformation or deflection of the first contact element decreases with the decline of the applied external force, so that the first contact element 35 returns to its rest position.
    [0003] In particular, the first contact element may have a restoring force, so that the first contact element automatically returns to a position remote from the second contact element. This facilitates the use of the audible warning device, since active activation is necessary to establish an electrical connection between the first contact element and the second contact element and, consequently, to generate a buzzer signal. The buzzer signal terminates as soon as the activation force bends and the restoring force becomes active, so that the two contact elements are brought apart from each other. A coordinated aspect of the invention is a steering wheel having a foam liner and a previously described buzzer which is secured in the foam liner. As already mentioned above, the arrangement of the audible warning device directly in the steering wheel makes it possible in particular to reduce the necessary space. As a result, it is possible to use airbag modules that have a relatively large interior volume. Finally, the maintenance expenses are reduced with the steering wheel according to the invention, since in the event of a malfunction of the audible warning device, it is unnecessary to dismantle the airbag module. Preferably, the anchoring lugs of the buzzer are firmly incorporated in the foam liner. The anchoring lugs may be configured to provide secure fixation of the horn in the foam liner. The position of the buzzer can be adjusted before curing the foam liner. With the steering wheel according to the invention, it is possible to provide for the deflection of the first contact element a control device which comprises at least one protrusion advancing toward the control section of the cage. In the activation position, the protrusion may engage inside the control section and deform the first contact element in the control section so that the first contact element comes into contact with the second element of the control element. contact. To form the control device, it is possible to provide an airbag module on which the projection is made. The projection may be carried out in particular on a lid of the airbag module. It is possible to provide that the cover protrudes laterally beyond a casing for the airbag, the projection being made on the protruding part of the lid. This also contributes to a better use of the space available on the steering wheel. The projection may further include a groove, which receives the first contact element. This makes it possible to prevent the first contact element from slipping off when the control device exerts an activation force on the first contact element in order to deform it. Overall, this increases the operational safety of the steering wheel according to the invention.
    [0004] The control device, in particular the airbag module, may comprise at least one guide sleeve, in which the guide pin of the cage slidably engages. The guide sleeve and the guide pin can be coupled in particular with a clearance, so that on the one hand, a positioning of the control device with respect to the steering wheel or the foam lining results. steering wheel and that it is possible, on the other hand, to make a relative movement between the control device and the foam lining of the steering wheel.
    [0005] The cage may further comprise an abutment which mechanically restricts movement of the control device, in particular of the airbag module, to actuate the horn. This thus makes it possible to prevent damage to the audible warning device as a result of the influence of an excessively high force. Finally, the invention is based on the idea of proposing a method for manufacturing a steering wheel described above, the method comprising the following steps: providing a steering wheel frame; - embedding the steering wheel frame with synthetic foam; - Provision of a warning device described above; - Depressing the anchoring lugs of a cage of the audible warning device in the foam lining; and curing the foam liner for attachment of the horn. The manufacturing method according to the invention can be implemented with low tolerances. In particular, because of the direct arrangement of the audible warning device in the foam padding of the steering wheel and the use of the audible warning device as a guide means and means for positioning a control device, in particular an airbag module, it is possible to suppress the long adjustment processes of the different steering wheels. This makes it possible to accelerate the production process, which has economic advantages. The invention is also based on the idea of proposing a method for manufacturing a steering wheel described above, the method comprising the following steps: providing a steering wheel frame; - embedding the steering wheel frame with synthetic foam to form the foam packing; - Fixing a warning device described above on the steering wheel, in particular on the foam lining thereof; coupling and positioning of an inflatable cushion module, in particular first guiding devices thereof, with respect to the audible warning device, in particular on second guiding devices carried out thereon. The manufacturing process according to the invention can be carried out with low tolerances. In particular, by providing guiding devices on the audible warning device and the airbag module, the audible warning device can serve as guiding means and positioning means for the airbag module 20, which makes it possible to reduce the tolerance range between the module and the parts of the steering wheel surrounding the module and, consequently, increase the manufacturing quality of the final product. This makes it possible to speed up the production process, which also has economic advantages. The invention will now be explained in more detail with reference to an exemplary embodiment with reference to the accompanying diagrammatic drawings, in which: FIG. 1 is a perspective view of a warning horn according to FIG. invention according to a preferred embodiment; Figure 2 is a detailed view of the audible warning device according to Figure 1; Figure 3 is a detailed profile view of the audible warning device according to Figure 1, in the mounted position in the steering wheel; Figure 4 is a bottom view of a cover for an airbag module; Figure 5 is a detailed perspective view of a steering wheel with the audible warning device according to Figure 1 integrated; Fig. 6 is an exploded view of the horn device according to Fig. 1; Figure 7 is a side view of the audible warning device according to Figure 1; and FIG. 8 is an elevational view of the audible warning device according to FIG. 1. The accompanying drawings show a horn 10 for a steering wheel 20. The horn 10 comprises a first contact element 11 and a second contact element 12, the two contact elements 11, 12 being arranged in a cage 13. The first and second contact elements 12, 12 are spaced apart from one another inside the cage 13. The cage 13 comprises in particular several activation sections 14 and several attachment sections 15. In each of the attachment sections 15 inside the cage 13 is disposed a separation spacer 16 or said separation spacer is made of in one piece with the cage 13. The spacer spacer 16 extends between the first contact member 11 and the second contact member 12. The separation spacer 16 comprises a mat 30 electrically insulating material, so as to avoid electrical contact between the first contact element 11 and the second contact element 12 in the area of the fixing section 15. The contact elements 11, 12 are freely spaced from one another. the other in the activation sections 14 of the cage 13. In other words, no additional element is arranged between the contact elements 11, 12. Under the effect of the application of a force, the two contact elements 11, 12 can be brought closer to one another inside the control section 14 of the cage 13, in order to establish an electrical contact. At the moment when the first contact element 11 comes into contact with the second contact element 12, it induces the closure of an electric circuit of the buzzer, which comprises a control module 19. Said control module 19 generates a sound signal, which is emitted as an acoustic buzzer signal via a loudspeaker. The two contact elements 11, 12 are connected to the control module 19 by cords 19a. The contact elements 11, 12 are preferably formed by wires which are arranged one above the other in the cage 13. The wires are fixed, preferably, by locking in the cage 13 and each comprise an end which is coupled respectively to a cord 19a. In the rest position, ie without activating a control device to trigger the buzzer function, no electrical contact is established between the contact elements 11, 12. In principle, the contact elements 11, 12 are each made of an electroconductive material, such as a metal wire. The activation of the buzzer function is preferably effected by the deformation of the first contact element 11 in the zone of the activation sections 14. As can be clearly seen in FIG. 1, the buzzer device 10 in FIG. the exemplary embodiment shown comprises altogether six activation sections 14, which are arranged at different locations of the annular cage 13. The activation sections 14 each comprise a recess 14a, in which a protrusion 32 of a control device can engage, in order to push the first contact element 11 against the second contact element 12. FIG. a detailed view of the audible warning device 10. It particularly represents a control section 14, in which the two son-shaped contact elements 11, 12 extend freely at a distance from one another. It will be seen that the second contact element 12 has a larger cross-sectional diameter than the first contact element 11. The second contact element 12, in this sense, forms a relatively rigid contact element, whereas the first contact element 12 contact element 11 is relatively flexible. The first contact element 11 is thus easily deformable to form a bulge towards the second contact element 12, until the first contact element 11 comes into contact with the second contact element 12 and thus closes the circuit electric horn. In FIG. 2, it is also clearly visible that the contact elements 11, 12 are arranged substantially parallel to each other inside the cage 13. In FIG. 2, it appears that an anchoring pin 17 is disposed in the area of each of the attachment sections 15, which are separated from each other by the control section 14. The anchor pin 17 is disposed laterally 25 on the cage 13 or is made of a The anchoring pin 17 extends substantially parallel to an activation plane, in which the deflection of the first contact element 11 is made to make contact with the second contact element 12. The anchor pin 17 has a tip 17a which is substantially hook-shaped. The tip 17a comprises at least one widening to obtain a good secure anchoring in a foam lining 24 of a steering wheel 20. In addition, in the anchor lug 17 is provided a longitudinal notch 17b which extends along the anchoring pin 17. The longitudinal notch 17b extends particularly from the tip 17a to a base 17c of the anchoring pin 17. The longitudinal notch 17b narrows from the tip 17a to the base 17c. The longitudinal notch 17b provides additional anti-rotation security for the cage 13 or the audible warning device 10 and thus improves the anchoring in the foam padding 24. From FIG. 1, it is visible that the audible warning device 10 comprises several anchoring lugs 1 7. The anchoring lugs 17 are preferably arranged on an outer face of the audible warning device 10. On the inside of the audible warning device 10, on the other hand, several lugs are provided. guidance 18 which extend in the opposite direction to the anchoring lugs 17. In addition, the guide lugs 18 may be arranged at the height of the anchoring lugs 17 or offset with respect thereto. The guide lugs 18 preferably comprise a transverse section with a T-shaped profile and are cut obliquely or trapezium-shaped at their free end 18a. This facilitates the insertion of the guide lugs 18 into complementary guide bushes 31. Additional guide bushes 31 may be arranged, for example, on a cover 30 of an airbag module or airbag module. A lid 30 of this type is shown by way of example in FIG. 4. It appears in FIG. 4 that the lid 30 has latching orifices 33 which allow the lid 30 to be assembled by engagement with an airbag casing. or an airbag module. The cover 30 may further comprise lines intended for breaking to allow the release of an airbag or airbag deploying explosively.
    [0006] The cover comprises a plurality of guide bushes 31, which are arranged in space in analogy to the guide lugs 18 of the audible warning device 10. The guide bushes 31 are made in one piece with the cover 30 and are dimensioned such that so that the guide pins 18 can engage with a play in the guide bushes. The guide pins 18 provide, in cooperation with the guide bushes 31, a positioning function for the cover 30. At the same time, the guide pins 18 are movable in the longitudinal axial direction in the guide bushes 31, such as so that the cover 30 can be used as a control device for triggering the horn function. For this purpose, the cover 30 further includes projections 32 which are made with a cross-shaped cross-section in FIG.
    [0007] The projections 32 are arranged in space complementary to the activation sections 14 of the audible warning device 10. The operating mode of the projections 32 in connection with the audible warning device 10 is clearly visible in FIG.
    [0008] FIG. 3 is a side view of a fragment of the audible warning device 10 in the position mounted in a steering wheel 20. The audible warning device 10 is fixed in a foam padding 24 of the steering wheel and is connected to the cover 30 through the guide lugs 18. The guide lugs 18 engage in particular in the corresponding guide bushes 31 of the cover 30. On the fragment according to Figure 3, a projection 32 is disposed between the guide bushes 31 which acts on the first contact element 11 in the region of the control section 14 of the cage 13. The projection 32 preferably has a height greater than the height of the guide bushes 31. In the rest position, the cover 30 is kept at a distance from the audible warning device 10.
    [0009] This results from the elastic return force of the first contact element 11 which acts against the projection 32 of the cover 30. Under the effect of an activation force, defined previously, applied to the cover 30, the projection 32 is pushed against the first contact element 11 so that the first contact element 11 deforms elastically. Therefore, the first contact element 11 forms, inside the control section 14, a bulge towards the second contact element 12. In the case of application of a minimum force, which has been defined in advance and can be defined in support of a corresponding material choice for the first contact element 11, the distance between the first contact element 11 and the second contact element 12 is suppressed, so that the first element of contact 11 is pushed against the second contact element 2. This results in the closure of the electric circuit of the buzzer and the control module 19 delivers a corresponding signal which is retransmitted as an acoustic signal via a loud speaker. Under the effect of the deformation of the first contact element 11 and the subsequent contact with the second contact element 12, it is possible, in addition, to deform, at least slightly, the second contact element 12. Where appropriate, it is provided that the first contact element 11 and the second contact element 12 slide over each other upon contact, so that the first contact element 11 and the second contact element 12 clean themselves in the control section 14. The electrical contacts of the audible warning device 10 are self-cleaning. The cage 13, which surrounds the contact elements 11, 12, further comprises, in the control section 14 a stop 13a, which limits the activation movement of the projection 32. The stop 13a is arranged, preferably below the second contact element 12. The mechanical stop 13a makes it possible to prevent the contact elements 11, 12 from being damaged, in particular severed, under the effect of an excessive load. In this context, it should be emphasized that a mechanical stop 13a may not be provided only in the control section 14. Another mechanical stop 13a may form the guide sleeve 31 which, after a sliding movement over a defined distance previously, rests on the cage 13 and, in this sense, abuts against the cage 13. The first contact element 11 has a return force which is sufficient to automatically return the control device, in this case the cover 30, in the rest position. In other words, the first contact element 11 automatically disposes parallel to the second contact element, as long as no activation force acts on the first contact element 11. FIG. 5 represents the audible warning device 10 in the position mounted inside a steering wheel 20. The steering wheel 20 may comprise, in principle, a frame 25 which comprises a central body 21 and connecting arms 22. The connecting arms 22 connect the central body 21 to a steering wheel crown not shown here. In the central body 21 is preferably a module housing 23. The module housing 23 serves to incorporate an airbag module.
    [0010] The control module 19 of the audible warning device 10 is preferably disposed in the central body 21 of the frame 25 of the steering wheel. The frame 25 of the steering wheel is enveloped by a foam padding 24. The foam padding of the steering wheel is tainted with relatively high tolerances and affects in particular the size of the slot of the horn, it is ie the distance between the steering wheel and the lid 30 of the airbag module. For discrepancies of the slot of the horn to be as small as possible between different steering wheels, it is generally necessary to make tedious adjustments of the cover 30 relative to the steering wheel 20. Greater accuracy is obtained with the present invention, wherein the horn device 10 is incorporated directly into the foam lining 24. In particular, the horn device 10 is fixed in the foam lining 24 by the anchoring lugs 17. The buzzer 10 can therefore be adjusted before driving into the foam lining 24 previously produced, so that after the cover 30 has been inserted by means of the guide lugs 18, a relatively precise positioning of the cover 30 is already obtained with respect to 20. FIG. 6 shows the audible warning device 10 in an exploded view. The first contact element 11 and the second contact element 12 which are in the form of wires each having open ends are clearly visible. In addition, the audible warning device 10 comprises the cage 13 and a control module 19. Furthermore, two cords 19a and two retractable ducts 19b are provided for connecting the control module 19 with the contact elements 11, 12. As a whole, it appears in FIG. 6 that the audible warning device comprises a relatively small amount of parts, which has advantages in terms of assembly and maintenance expenses as well as manufacturing costs. The audible warning device 10 is shown in a side view and an elevational view respectively in FIGS. 7 and 8. In FIG. 7, it can be seen that the cage 13 has a bend 136 in an upper part in FIG. The bend 136 is adapted to properly adjust the cage 13 to the shape of the steering wheel 20. In Fig. 8, it will be seen that the annular cage 13 substantially has a square outline with rounded corners. Other shapes are possible and will be chosen accordingly by those skilled in the art in support of the desired design for the steering wheel 20 to be manufactured.
