Description

[0001] The present invention relates to a fastening device for securing components, particularly airbags, to carrier components.

[0002] DE 10 201 0034 006 A1 discloses a fastening clip having a spring clip and a locking bolt, the spring clip being configured to lock into a carrier, and the locking bolt being configured to lock the spring clip into the carrier. The spring clip has at least one locking element that is elastically movable between an initial position, an intermediate assembled position, and an assembled position. The locking bolt has at least one safety element that works in conjunction with the locking element such that the locking bolt can only be displaced from the initial position to the locked position when the locking element is in the assembled position. When the spring clip is in the unassembled state, the locking element of the spring clip is in an unloaded position, which is defined here as the initial position. During the insertion of the spring clip into the carrier, the spring elements are pushed open by the opening edge, thereby displacing these spring elements to the loaded intermediate assembled position. When the spring clip is fully inserted, the locking element is locked onto the carrier in the assembled position. Depending on the shape of the carrier, this assembled position may also coincide with the initial position. In the assembled position, the bolt secures the locking element of the spring clip after the fastening clip has been installed, resulting in a very large pull-out force required to remove the fastening clip (if necessary). To prevent the bolt from being inserted into the spring clip before assembly, the bolt has a safety element that works in conjunction with the locking element to prevent the bolt from being inserted into the spring clip in the initial and intermediate assembled positions. The bolt is only released when the spring clip is fully assembled and the locking element is locked in the assembled position, allowing the bolt to be inserted into the locked position. This reliably prevents premature bolt insertion. Alternatively, the full assembly of the fastening clip can be visually checked, as the bolt cannot be inserted if the fastening clip is not properly assembled, resulting in the bolt protruding from the spring clip.

[0003] DE 102 018 006 297 A1 discloses a multi-piece clamp for fastening one component to another. The clamp includes a first member and a fixing mechanism, wherein the first member has a head and a rod extending away from the head along a rod axis, the rod having an end, wherein the rod has a base and a locking element, wherein the locking element has a contact surface facing away from the end, and the head has a contact surface facing the end, wherein the locking element is movable between a first position and a second position, wherein in the first position a portion of the locking element protrudes from the base of the rod, and in the second position the locking element either protrudes less from the base than in the first position or not at all, wherein an inspection area is provided in the base of the rod, wherein when the locking element is in the first position, no part of the locking element is located in the inspection area, and when the locking element is in the second position, a portion of the locking element is located in the inspection area, wherein the fixing mechanism… The device has an outer portion configured to remain outside the component and an inner portion that can be inserted into the base in an insertion direction until a final position is reached. The inner portion has a retaining pin having a portion that reaches an inspection area when the inner portion is inserted to the final position. The retaining pin also has a lug extending at an angle to the insertion direction. In an intermediate position where the inner portion is partially inserted into the base but has not yet reached the final position, the lug engages with an opening in the base of the rod and contacts the edge of the opening, thereby preventing further insertion beyond the intermediate position. The lug can be squeezed in a direction toward the interior of the base until the retaining mechanism can be inserted further beyond the intermediate position. The device is characterized in that, in the intermediate position, the retaining pin does not contact a locking element in a first position.

[0004] Such fastening devices are also known from US 2015 / 0300388 A1, DE 601 26 229 T2, or DE 102 55 902 A1. These fastening devices are used to secure components in vehicles.

[0005] The purpose of this invention is to provide a fastening device that is safe and reliable during operation.

[0006] Another object of the present invention is to provide an integrated, simple assembly verification device that does not require auxiliary tools for operation.

[0007] One or more of these objectives are achieved by a fastening device as defined in independent patent claim 1. Advantageous embodiments are given in the dependent claims relating to claim 1.

[0008] According to the present invention, a fastening device for fastening a component to a carrier component is provided. The fastening device includes: a housing device having a receiving recess, at least one actuating element, and at least one locking element for locking in the carrier component; and a pin device disposed in the receiving recess of the housing device in a manner displaceable along an assembly direction, the pin device having at least one movable pin arm having a pin locking mechanism for transmitting an assembly force acting along the assembly direction to a rigid housing locking mechanism integrally formed on the housing device, preferably arranging the fastening device in an intermediate assembly position, wherein the housing locking mechanism is designed to correspond to the pin locking mechanism, and wherein the actuating element is designed to actuate the at least one pin arm.

[0009] The present invention preferably relates to a fastening device that can be used to secure airbags in a vehicle.

[0010] To this end, the housing assembly of the fastening device is inserted through the opening of the airbag and subsequently into the component opening of the carrier component. Then, a force acting in the assembly direction is applied to the pin assembly.

[0011] According to a first aspect, the invention is characterized in that at least one movable locking arm of the pin device directly transmits the assembly force acting in the assembly direction to a rigid housing locking mechanism integrally formed on the housing device via a pin locking mechanism, and thus to the housing device. Since the assembly force initially acts only on the housing locking mechanism formed on the housing device and not on movable or flexible components (e.g., locking elements), these components are not continuously subjected to assembly force, which could lead to unintentional jamming of the locking elements or jamming in component openings, especially locking of the locking elements. Therefore, components can generally be assembled smoothly and reliably by means of the fastening device. Furthermore, the assembly force thus does not affect the verification function of the fastening device.

[0012] Furthermore, according to the second aspect, the fastening device is characterized in that the actuating element is configured to actuate at least one pin arm. In this way, the pin arm is not directly actuated by the edge of the component opening, but rather achieves indirect contact, because the movable pin arm is actuated by means of the actuating element. This indirect contact is more process-reliable because the (surface) characteristics and (manufacturing) quality of the edge of the component opening do not directly affect the function and mobility of the pin arm. Therefore, this essentially closed system is independent of external factors that may adversely affect the assembly.

[0013] According to the fixture disclosed in DE 102 018 006 297 A1, the retaining pin does not contact the locking element in the first position in the intermediate position. Thus, the retaining pin is disengaged from the locking element in the first position in the intermediate position. This should have the advantage that when the locking element moves from the first position to the second position, it cannot displace the retaining pin. Therefore, the locking element also cannot eliminate the contact between the lug of the retaining pin and the edge of the opening in the base. In this case, the fixing mechanism should be securely held in the intermediate position independently of the movement of the locking element. This should be advantageous in the pre-assembly stage, where the locking element is pressed in while the fixing mechanism remains in the intermediate position. Until final assembly (where the retaining pin is in the final position in the case of final assembly), it should be ensured that the retaining pin does not undesirably fall out of the component. Another advantage of this fixture is that the locking element is in the second position in the pre-assembly state, while the retaining pin is securely held in the intermediate position until it is subsequently brought to the final position in a subsequent assembly step. There is no interaction between the locking element and the retaining pin in the intermediate position, so new applications in assembly, such as staged assembly, should be possible.

[0014] The problem with such fastening devices is that coordinating the timing of swinging the locking element out behind the carrier member and releasing the movable arm (e.g., the lug of the retaining pin) more or less simultaneously from the force-transmitting connection with the housing used to transmit assembly forces is crucial to prevent the fastening device, especially its locking element, from becoming stuck in the opening of the carrier member. For the fixture disclosed in DE 102 018 006 297 A1, these two processes must be coordinated very precisely in time. In the worst case, the lug of the retaining pin may prematurely detach from the housing and thus slide downwards before the locking element is reliably locked into the carrier member.

[0015] If this cannot be done precisely in time, the component must be further pressed along the assembly direction. Then, the locking element swings out, and the retaining pin is only engaged by the lugs via the edge of the component opening when the component is further pressed along the assembly direction. This results in compression of the component to be fastened (e.g., an airbag module) and may lead to increased assembly forces. In other words, to actuate the lugs of the retaining pin via the edge of the component opening, the clamp must continue to move along the assembly direction after the locking element swings out behind the metal plate of the carrier component in its final assembly position.

[0016] In the fastening device according to the invention, there is a direct connection and thus a dependency between the pin arm of the pin device and the locking element. That is, the pin element of the pin device can transition from an intermediate assembly position to the final assembly position without slippage because the pin element is blocked by the locking element, and the pin element or pin device immediately moves into the final assembly position after being locked by the locking element. Therefore, the device according to the invention is highly reliable and avoids assembly problems.

[0017] According to another aspect, the pin device may have a rigid pin element having a frontal face in the assembly direction, which is designed to transmit forces acting in the assembly direction to at least one locking element of the housing device, so as to preferably arrange the fastening device in the final assembly position.

[0018] If the pin arm has already swung inward due to the actuating element after reaching the intermediate assembly position, the assembly force is transmitted via the pin element to the inwardly swung locking element. The assembly force transmitted via the pin arm continues to act primarily on the locking arms along the assembly direction (downward), however, these locking arms are held in place by the edge of the component opening and thus exert a reaction force on the rigid pin element. However, a certain component of the assembly force acts outward at a predetermined angle, so that the main force has acted along the assembly direction to reach the final assembly position. At the same time, however, upon reaching the final assembly position, the outward force component of the assembly force also ensures the deployment of the locking element (locking arm), and therefore additionally ensures reliable assembly. Thus, the secure and reliable swing deployment and locking of the locking element is ensured. Furthermore, the assembly is thus simplified.

[0019] According to another aspect of the invention, two corresponding actuating elements and two locking elements may be formed on the housing device, the two corresponding actuating elements and the two locking elements being arranged on adjacent sidewalls of the housing device such that the two corresponding actuating elements are arranged opposite each other and offset from each other in the assembly direction, such that the locking elements are arranged in front in the assembly direction and the actuating elements are arranged behind in the assembly direction.

[0020] Because the actuating elements are offset by 90° or arranged on different sidewalls of the housing assembly, and because the assembly force is first applied to the rigid housing and then immediately to the locking element, the force is safely and reliably transmitted to the locking element along the assembly direction, which swings inward due to the edge of the component opening. The advantages shown above apply similarly here.

[0021] According to another aspect of the fastening device of the invention, in the final assembly position, the pin element is arranged between these locking elements such that movement of these locking elements is prevented in the final assembly position, thereby fixing the fastening device in the final assembly position.

[0022] Therefore, upon reaching the final assembly position, the pin elements are positioned in the area between the locking elements to prevent them from swinging inward. The fastening device secures the device firmly and reliably in the final assembly position.

[0023] Furthermore, a verification portion extending laterally to the assembly direction may be provided at the end of the pin device opposite to the assembly direction. This verification portion may be arranged completely, preferably flush with the surface, in the recess of the housing device at the final assembly position.

[0024] The verification part of the pin device, together with the corresponding notch of the housing device, constitutes a verification device, by means of which it is easy to visually and tactilely determine whether the fastening device is correctly arranged or assembled in the final assembly position.

[0025] In particular, locking wings may be provided on this verification section, having at least one and preferably two pre-assembly locking mechanisms and / or at least one and preferably two final assembly locking mechanisms, wherein the pre-assembly locking mechanisms secure the housing device and the pin device relative to each other in the pre-assembly position, and / or the final assembly locking mechanisms secure the housing device and the pin device relative to each other in the final assembly position.

[0026] By providing at least one, and preferably two, pre-assembled locking mechanisms to the locking wing, the pin device and the housing device are fixed relative to each other in the transport / pre-assembled position. In this way, the pin device is subjected to a force acting in the assembly direction and is fixed to prevent displacement in the opposite direction of the assembly direction.

[0027] Furthermore, the transport fixing device for the pin device can be composed of the aforementioned pin locking mechanism and housing locking mechanism. In this way, the pin device is applied with a force opposite to the assembly direction and is fixed to prevent displacement along the assembly direction.

[0028] This forms a transport fixing device, and the fastening device according to the invention can be delivered as a prefabricated unit, allowing it to be assembled onto the carrier component as a unit. Furthermore, it prevents the pin device and housing device of the fastening device from becoming loose from each other or the pin device from falling off the housing device.

[0029] The cause of the fall could be, for example, forces acting during the transport of the pre-assembled fastening equipment, causing the pin to dislodge from the housing assembly. Another cause could be, for example, the weight of the pin.

[0030] Furthermore, a locking wing with at least one, and preferably two, final assembly locking mechanisms can be provided, which secure the pin assembly and the housing assembly relative to each other in their final assembly positions. This ensures that the fastening device cannot detach from the carrier component, and in particular, that the airbag can be securely and reliably assembled.

[0031] Furthermore, a stop element may be formed on the pin device, the stop element having a stop surface for limiting the displacement of the pin device in the receiving recess of the housing device along the assembly direction, wherein a corresponding mating stop surface is formed on the housing device.

[0032] By means of a stop surface for limiting displacement of the pin device in the receiving recess of the housing device and a corresponding mating stop surface formed on the housing device, the pin device is prevented from being over-introduced into the housing device. In addition, the user receives tactile feedback indicating that the pin device no longer needs to be subjected to a force acting in the assembly direction, thereby allowing the locking element to swing out and the fastening device to be locked in the carrier member.

[0033] Preferably, the housing assembly and the pin assembly can be made of one and the same plastic or of two different plastics. The plastic can be a thermoplastic material, such as polyamide (PA) or polyoxymethylene (POM).

[0034] Because the fastening device is made entirely of plastic, it can be manufactured simply and cost-effectively.

[0035] In addition, the housing device may have a fastening surface extending transversely to the assembly direction to fix the fastening portion of the component to be fastened, preferably the fastening portion of the airbag, between the fastening surface and the surface of the carrier component extending parallel to the fastening surface.

[0036] At least one spring element may be provided in the area of ​​the fastening surface to apply a spring force acting in the assembly direction to the component to be fastened at the final assembly position.

[0037] Applying a spring force acting in the assembly direction to the component to be fastened ensures the precise positioning of the component.

[0038] Furthermore, according to the present invention, a method is proposed for introducing fastening equipment into a component opening of a carrier component or for transferring from a transport position / pre-assembly position through an intermediate assembly position to a final assembly position.

[0039] This method will now be described in detail with the aid of exemplary embodiments.

[0040] The advantages of the invention described above, achieved by means of fastening devices, also apply to the method according to the invention.

[0041] The invention will now be described in more detail with the aid of exemplary embodiments shown in the accompanying drawings. In the drawings:

[0055] According to the invention, the fastening device 1 for fastening a component, preferably an airbag, to a carrier component 4 includes a housing device 2 and a pin device 3. Figures 1 to 13 ).

[0056] The fastening device 1 is designed to fasten a component (not shown) to a carrier component 4. The carrier component 4 has a corresponding component cutout 5 in which the fastening device 1 can be fixed. The fastening device 1 can be introduced into the component opening in an assembly direction 6 extending transversely to the component surface of the carrier component 4.

[0057] In the side view, the housing 2 of the fastening device 1 is designed to be generally T-shaped, wherein the housing 2 includes a verification part 7 and a fastening part 8.

[0058] The verification section 7 is designed to be generally box-shaped and includes four side walls 9, 10, 11, 12 and a bottom wall 13. These four side walls 9, 10, 11, 12 and the bottom wall 13 are part of the receiving recess 35 of the verification section 7.

[0059] A receiving opening 14 for receiving the pin device 3 is formed in the bottom wall 13.

[0060] On the two opposite sidewalls 9, 10, 11, and 12 of the fastening area, locking cutouts 15 and 16 are designed as through openings, and these locking cutouts have locking edges 17 and 18 extending in the horizontal direction.

[0061] The bottom wall 13 of the box-shaped verification area 7, facing away from the assembly direction 6, forms a mating stop surface 19. The bottom wall 13, facing the assembly direction 6, forms a fastening surface 20 for securing the component to be fastened.

[0062] Four spring elements 21 are integrally formed in the corner area of ​​the fastening surface 20 to apply the spring force acting in the assembly direction 6 to the component to be fastened.

[0063] The fastening part 8 is designed to be generally rectangular and transforms into the verification part 7 in the area of ​​the receiving opening 14 and extends in the assembly direction 6.

[0064] The fastening part 8 has four side walls 22, 23, 24, 25 and a bottom wall 26 located in front in the assembly direction.

[0065] In the locking region 27 of the fastening part 8, which is located in front in the assembly direction 6, locking elements 28 and 29, which are designed to be approximately wedge-shaped, are arranged in two opposite sidewalls 22 and 23.

[0066] The wedge-shaped locking elements 28 and 29 are hinged to the corresponding sidewalls 22, 23, 24, and 25 of the housing device 2 via their edges (which are forward in the assembly direction and extend transversely to the assembly direction 6), such that these wedge-shaped locking elements are designed to pivot substantially transversely to the assembly direction 6. Furthermore, the locking elements 28 and 29 have locking surfaces / force transmission surfaces 30 and 31 extending substantially transversely to the assembly direction.

[0067] In the area between the locking area 27 and the verification part 7, the actuation area 32 is provided on the fastening part 8.

[0068] In the actuation region 32, actuation elements 33 and 34 are disposed in two opposite sidewall regions 24 and 25 and are adjacent to locking elements 28 and 29.

[0069] Actuating elements 33 and 34 are designed to be generally wedge-shaped and are hinged to the corresponding sidewalls 24 and 25 of the fastening portion 8 by means of their forward edges in the assembly direction 6. Similar to locking elements 28 and 29, actuating elements 33 and 34 can be displaced or tilted generally laterally in the assembly direction 6.

[0070] The side walls 22, 23, 24, and 25 of the fastening section 8 and the bottom wall 6 define the receiving recess 35 of the housing device 2.

[0071] In the region of the receiving recess 35 opposite to the assembly direction 6, stepped housing locking mechanisms 36 and 37 are formed in the region of the actuating elements 33 and 34.

[0072] The pin device 3, which can be displaced in the receiving recess 35 and in the assembly direction 6, will be described in more detail below.

[0073] The pin device 3 is also designed to be generally T-shaped and has a plate-shaped verification element 38 that extends generally laterally to the assembly direction. In the final assembly position 39, the verification element 38 can be arranged flush with the box-shaped verification portion 7 of the housing device 2, such that the verification surface 40 opposite to the assembly direction terminates at a position flush with the edges of the side walls 9, 10, 11, 12 of the verification portion 7 opposite to the assembly direction.

[0074] Furthermore, locking wings 41 are integrally formed on two opposite edges of the verification element, each having a pre-assembly locking mechanism 42 and a final assembly locking mechanism 43.

[0075] A rectangular stop element 44 is integrally formed on the front surface of the verification element 38 in the assembly direction 6.

[0076] The front surface of the stop element 44 in the assembly direction 6 forms a stop surface 45, which is designed to limit the displacement of the pin device 3 in the assembly direction. The stop surface 45 is configured to abut against the mating stop surface 19 of the housing device 2.

[0077] The stop element 4 is provided with pin arms 46 and 47 that can be displaced laterally to the assembly direction 6 and extend substantially in the assembly direction 6. Pin locking mechanisms 48 and 49 that extend substantially laterally to the assembly direction 6 are formed on the pin arms 46 and 47.

[0078] The pin locking mechanisms 48 and 49 are configured to transmit the force acting on the pin device 3 along the assembly direction 6 to the housing device 2 via the housing locking mechanisms 36 and 37. In this way, the fastening device 1 can be displaced in the assembly direction until it reaches the intermediate assembly position 52.

[0079] Pin arms 46 and 47 can be moved laterally in the assembly direction 6 by means of the actuating elements 33 and 34 of the housing device 2.

[0080] In the region between pin arms 46 and 47, a pin element 53 extending in the assembly direction is disposed on a stop element 44.

[0081] The pin element extends beyond the free ends of the pin arms 46, 47 in the assembly direction 6 and has a force transmission surface 54 located forward in the assembly direction 6. The surface 54 is curved or bent in the direction toward the locking elements 28, 29.

[0082] Surface 54 is configured to apply forces acting in the assembly direction to locking elements 28, 29 or force transmission surfaces 30, 31 of the locking elements, so as to transition the pin device 3 from intermediate assembly position 52 to final assembly position 39.

[0083] The following describes a method for introducing fastening equipment into the component opening 5 of the carrier component 4 or for transitioning from the transport position / pre-assembly position 55 to the final assembly position 39 via the intermediate assembly position 52. Figures 5 to 10 ).

[0084] First, the fastening device 1 is introduced into the component opening 5 of the carrier component 4 along the assembly direction 6, so that the fastening part 8 of the housing device 2 is arranged in the component opening 5.

[0085] The force is transferred from the user to the fastening device 1 by applying a force acting in the assembly direction 6 to the pin device 3, especially the verification element 38 of the pin device 3.

[0086] In the transport / pre-assembly position 55, the pin device 3 is generally arranged in the receiving recess 35 of the housing device 2, wherein the pre-assembly locking mechanism 42 of the verification element 38 engages from the rear the locking edges 17, 18 of the locking cutouts 15, 16 of the verification part 7. In this way, the pin device 3 is securely and reliably held in the housing device 2, thereby ensuring that the pin device 3 and the housing device 2 are securely and reliably connected to each other during transport and that the same initial position is always ensured before the assembly fastening device 1 is assembled.

[0087] The force acting on the pin device 3 is transmitted through the pin arms 46, 47 and the corresponding pin locking mechanisms 48, 49 to the corresponding housing locking mechanisms 36, 37, until it reaches the intermediate assembly position 52.

[0088] When the fastening device 1 reaches the intermediate assembly position by shifting along the assembly direction 6, the actuating elements 33 and 34 contact the edge of the component opening 5 and further shift in the direction toward the receiving recess 35, and doing so also causes the pin arms 46 and 47 to shift further toward each other.

[0089] After reaching the intermediate assembly position 52, the pin arms 46 and 47 are displaced laterally in the assembly direction and toward each other by means of the actuating elements 33 and 34, so that the pin locking mechanisms 48 and 49 are no longer engaged with the housing locking mechanisms 36 and 37.

[0090] After the pin locking mechanisms 48 and 49 no longer engage with the housing locking mechanisms 36 and 37, the equipment 1 is no longer in the intermediate assembly position 52.

[0091] Then, the force acting in the assembly direction 6 to introduce the fastening device into the carrier member 4 is no longer applied via the pin arm and the rigid part of the housing device 2 located in the receiving recess (on which the housing locking mechanism 36, 37 is integrally formed), but the surface 54 of the pin element 53 transmits the force to the force transmission surfaces 30, 31 of the locking element, and these force transmission surfaces also contact the edge of the member opening 5 and are thus arranged almost entirely in the receiving recess 35.

[0092] Force transmission continues from the surface 54 of the pin element 53 to the force transmission surfaces 30 and 31 of the locking element until the final assembly position 39 is reached.

[0093] When the fastening device 1 is fully introduced into the component opening 5 of the carrier component 4 along the assembly direction, the locking elements 28 and 29 are no longer held by the edge of the component opening of the carrier component or pressed inward. Instead, they swing outward in the assembly direction by the outward force component of the assembly force, so that the locking elements 28 and 29 engage the component opening 5 from the rear or lock behind the component opening.

[0094] In order to restrict the movement of the pin element 53 along the assembly direction 6, the stop surface 45 of the stop element 44 of the pin device stops on the mating stop surface 19 of the housing device 2 in the area of ​​the verification part 7.

[0095] At this time, the locking wing 41 or its pre-assembled locking mechanism 42 also disengages from the locking notches 15, 16, and the final assembly locking mechanism 43 of the locking wing 41 engages from the rear the locking edges 17, 18 of the locking notches 15, 16 to secure the pin device 3 in the housing device 2 in the final assembly position 39. Upon reaching the final assembly position, when the locking wing is locked and the stop surface 45 abuts against the mating stop surface 19, the verification surface 40 of the verification element is arranged in a receiving recess in the area of ​​the verification portion 7, such that the edges of the sidewalls 9, 10, 11, 12 opposite to the assembly direction terminate at a position flush with the verification surface 40, thereby ensuring that the verification surface is fully received in the verification portion 7 of the housing device 2.
