The present disclosure relates generally to the field of automotive protection. More specifically, the present disclosure relates to automotive protective device tracking, including trackable automotive protective devices and systems and methods of manufacturing the same, for quality control, safety control, manufacture process data collection, and/or other tracking applications.
Inflatable airbags are examples of automotive protective devices that may be mounted within a vehicle and deploy during a collision event. The deployed airbag may cushion an occupant and prevent detrimental impact with other vehicular structures. Some airbags suffer from one or more drawbacks or may perform less than optimally in one or more respects. Safety belts are also examples of automotive protective devices that provide restraint of an occupant of a vehicle during a collision event. Some safety belts suffer from one or more drawbacks or may perform less than optimally in one or more respects. Certain embodiments disclosed herein can address one or more of these issues.
The present embodiments will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that the accompanying drawings depict only typical embodiments, and are, therefore, not to be considered limiting of the scope of the disclosure, the embodiments will be described and explained with specificity and detail in reference to the accompanying drawings.
As can be readily understood, the components of the embodiments as generally described and illustrated in the figures herein could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the disclosure, as claimed, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
Automotive protective devices may be used to prevent or mitigate injury to an automotive vehicle occupant in the event of a crash. Automotive protective devices may include seatbelts, airbags, nets, cushions, and other devices. Automotive protective devices may mitigate injuries caused by rapid deceleration of the vehicle occupant in the event of a crash. Automotive protective devices may prevent collision of the vehicle occupant with vehicle structures such as a beam, a dashboard, or other structures.
Inflatable airbag systems are widely used to reduce or minimize occupant injury during a collision event. Airbag modules have been installed at various locations within a vehicle, including, but not limited to, in the steering wheel, in the dashboard and/or instrument panel, within the side doors or side seats, adjacent to a roof rail of the vehicle, in an overhead position, or at the knee or leg position.
During installation, the disclosed airbags are typically disposed at an interior of a housing in a packaged state (e.g., are rolled, folded, and/or otherwise compressed) or a compact configuration and may be retained in the packaged state behind a cover. During a collision event, an inflator is triggered, which rapidly fills the airbag with inflation gas. The airbag can rapidly transition from the packaged state of the compact configuration to an expanded state of a deployed configuration. For example, the expanding airbag can open an airbag cover (e.g., by tearing through a burst seam or opening a door-like structure) to exit the housing. The inflator may be triggered by any suitable device or system, and the triggering may be in response to and/or influenced by one or more vehicle sensors.
An airbag assembly, or airbag system, can mitigate injury to an occupant of a vehicle during a collision event by reducing the effect of impact of the occupant against structures (body-structure impact) within the vehicle (such as, e.g., a dashboard, or door column).
Seat belts, or restraining devices have been used to restrain passengers and mitigate injuries due to vehicle collisions. Seat belts may include a lap belt and a shoulder belt. Seat belts may buckle to secure a vehicle occupant in a vehicle occupant seating position. Seat belts may extend from a spooled configuration to extend over an occupant. Seat belts may include mechanisms which prevent them from extending during a collision. Some seat belts may include mechanisms which prevent seat belts from extending at speeds exceeding a threshold.
To successfully protect vehicle occupants in the event of a collision, automotive protective devices must be reliable. Some automotive protective devices do not function correctly after being used. For example, some airbags can only be used once. Thus, quality controls are an important part of manufacturing automotive protective devices. Batch testing of automotive protective devices, along with other manufacturing controls, may ensure reliability of automotive protective devices. In some instances, recalls are required to ensure that automotive protective devices will function properly. In the case of recall, it is important to know which automotive protective devices are affected by the recall. Recalling too few devices may result in some unreliable devices remaining in vehicles while recalling too many devices may result in waste.
Conventional systems for tracking automotive protective devices during manufacture often rely on scanning bar code labels attached to automotive protective device components. These systems require workers to locate and correctly scan the bar code labels on the automotive protective device components, delaying the manufacturing process. Additionally, some bar code labels cannot be scanned once the automotive protective devices are assembled. For example, internal components of the automotive protective devices may have bar code labels which are not visible and which cannot be scanned when the automotive protective devices are assembled.
In some embodiments, the RFID thread 200 may be incorporated in a seam tape. In some embodiments, the RFID thread 200 may be incorporated in the seam tape as the seam tape is produced. The RFID thread 200 may be integral to the seam tape. The seam tape may be used to join seams of an airbag cushion during sewing of the airbag cushion. In some embodiments, the plurality of RFID chips 220 may each emit the same signal or identifier. During sewing of the airbag cushion, a subset of the plurality of RFID chips 220 may be destroyed and a second subset of the plurality of RFID chips 220 may survive. During deployment of the airbag cushion, a third subset of the second subset of the plurality of RFID chips 220 may be lost and a fourth subset of the second subset of the plurality of RFID chips 220 may remain on the airbag cushion such that the airbag cushion may be identified using the signal or identifier of the plurality of RFID chips 220.
In some embodiments, the stitching 640 may include metal thread or metal-coated thread and may cross the antenna, allowing the stitching 640 to function as an additional antenna. In some embodiments, the RFID ribbon 610 may not include an antenna and the stitching 640 may contact a lead of the RFID chip to function as the antenna. In some embodiments, the stitching may cross the RFID chip area 615 to contact the antenna and/or the lead of the RFID chip.
The assembly station 1020 may be a location for assembling the automotive protective device 1010. The textile component 1012 and/or the non-textile component 1014 may be added to the automotive protective device 1010 at the assembly station 1020 at an assembly time, or coupling time. The assembly time may be a time when the textile component 1012 and/or the non-textile component 1014 are added or coupled to the automotive protective device 1010. In an example, the non-textile component 1014 is coupled to the textile component 1012 at the assembly time. In some embodiments, multiple assembly stations may be used in assembling the automotive protective device 1010. The scanner 1022 may scan the RFID chip 1013 and identify an identifier of the RFID chip 1013. Scanning the RFID chip 1013 may include emitting electromagnetic radiation which stimulates the RFID chip 1013 to emit a signal containing the identifier, and parsing the signal emitted by the RFID chip 1013 to identify the identifier. The assembly station may transmit the identifier to the database 1030. The identifier may be associated with the automotive protective device 1010 in the database 1030. In some embodiments, the identifier may be associated with the automotive protective device 1010 in the database 1030 at the assembly time. The textile component 1012 may be associated with the identifier in the database 1030. The non-textile component 1014 may be associated with the identifier in the database 1030. In some embodiments, the non-textile component 1014 may be associated with the identifier in the database 1030 at the assembly time. In an example, the non-textile component 1014 is identified and then associated with the identifier in the database 1030 when the non-textile component 1014 is coupled to the textile component 1012 at the assembly time. In some embodiments, the assembly station 1020 may associate the automotive protective device 1010, the textile component 1012, and/or the non-textile component 1014 with the identifier in the database 1030. In other embodiments, the database 1030 may associate the automotive protective device 1010, the textile component 1012, and/or the non-textile component 1014 with the identifier based on an identity of the assembly station 1020. The assembly station 1020 may receive information associated with the non-textile component 1014 and transmit that information to the database 1030.
In some embodiments, the automotive protective device 1010 includes multiple RFID chips. In some embodiments, the automotive protective device 1010 includes multiple textile components each including an RFID chip, as well as multiple non-textile components, as discussed herein. Each textile component of the multiple textile components may be associated in the database 1030 with the identifier of the RFID chip in each textile component. As the multiple textile components are added to the automotive protective device 1010, the automotive protective device 1010 can be associated in the database 1030 with the identifier of each RFID chip in each textile component. In some embodiments, the multiple textile components include a first textile component of the automotive protective device and additional textile components. As the additional textile components are added to the automotive protective device 1010, the additional textile components are associated with the identifier of the RFID chip of the first textile component. In some embodiments, the multiple non-textile components are associated with different identifiers. For example, an inflator of the automotive protective device 1010 is associated with a first identifier of a first RFID chip incorporated in an airbag panel based on the inflator being installed subsequent to the airbag panel and a mounting hardware of the automotive protective device 1010 is associated with a second identifier of a second RFID chip incorporated in a tether based on the mounting hardware being installed subsequent to the tether.
In some embodiments, the scanner 1022 scans the RFID chip 1013 before the textile component 1012 is added to the automotive protective device 1010. In other embodiments, the scanner 1022 scans the RFID chip 1013 after the textile component 1012 is added to the automotive protective device 1010.
In some embodiments, the quality assurance station 1040 may organize the automotive protective devices into batches. The quality assurance station 1040 may organize the textile components of the automotive protective devices into batches. The quality assurance station 1040 may organize the non-textile components of the automotive protective devices into batches. Based on an automotive protective device, a textile component, or a non-textile component of a batch having an issue, the other devices or components in the batch may also be associated with the issue in the database. The quality assurance station 1040 may issue a recall alert on all of the devices and/or components associated with the issue.
The method may include associating 1110, in a database, an identifier of an RFID chip of a textile component of an automotive protective device with the textile component. The RFID chip may be incorporated in an RFID chip or RFID ribbon in or attached to the textile component, as discussed herein. The identifier of the RFID chip may be identified by scanning the RFID chip and capturing a signal containing the identifier emitted by the RFID chip in response to scanning. The identifier of the RFID chip may be identified by additional scanners, allowing the identifier of the RFID chip and, using the database, the textile component and/or the automotive protective device, to be identified.
The method may include incorporating 1120 a non-textile component into the automotive protective device. Incorporating 1120 the non-textile component into the automotive protective device may include assembling the automotive protective device including the non-textile component.
The method may include associating 1130, in the database, the non-textile component with the identifier of the RFID chip. The non-textile component may be identified using the identifier of the RFID chip such that scanning the RFID chip allows for identifying the non-textile component.
For example, the textile component may be an airbag cushion of an airbag assembly and the airbag cushion and/or airbag assembly may be identified by scanning an RFID chip incorporated into an RFID thread in the airbag cushion. In this example, the non-textile component may be an inflator of an airbag assembly and incorporating the inflator into the airbag assembly may include attaching the inflator to the airbag cushion of the airbag assembly. In this example, the inflator of the airbag assembly may be associated, in the database, with the identifier of the of the RFID chip such that scanning the RFID chip in the textile component allows for identifying the non-textile component.
Throughout this specification, the phrases “coupled to” and “in communication with” refer to any form of interaction between two or more entities, including mechanical, electrical, magnetic, electromagnetic, fluid, and thermal interaction. Two components may be coupled to each other even though they are not in direct contact with each other. The terms “abut” and “abutting” refer to items that are in direct physical contact with each other, although the items may not necessarily be attached together.
As used herein, inboard refers to a direction toward a centerline of a vehicle and outboard refers to a direction out of the vehicle and away from a centerline of the vehicle.
The phrases “attached to” or “attached directly to” refer to interaction between two or more entities which are in direct contact with each other and/or are separated from each other only by a fastener of any suitable variety (e.g., mounting hardware or an adhesive).
The phrase “fluid communication” is used in its ordinary sense, and is broad enough to refer to arrangements in which a fluid (e.g., a gas or a liquid) can flow from one element to another element when the elements are in fluid communication with each other.
The terms “a” and “an” can be described as one, but not limited to one. For example, although the disclosure may recite an airbag having “a chamber,” the disclosure also contemplates that the airbag can have two or more chambers.
The terms “longitudinal” and “longitudinally” refer to a direction or orientation extending or spanning between a front of a vehicle and a rear of the vehicle.
As used herein, the terms “forward” and “rearward” are used with reference to the front and back of the relevant vehicle. For example, an airbag cushion that deploys in a rearward direction deploys toward the back of a vehicle. Furthermore, other reference terms, such as horizontal, are used relative to a vehicle in which an airbag assembly is installed, unless it is clear from context that a different reference frame is intended. Thus, a term such as “horizontal” is used relative to the vehicle, whether or not the vehicle itself is oriented horizontally (e.g., is positioned upright on level ground) or angled relative to true horizontal (e.g., is positioned on a hill).
Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints.
The phrase “vehicle seating position” refers to the position in which an occupant is generally positioned when seated in a seat of a vehicle. The term “occupant” refers to a person or crash test dummy within a vehicle.
Reference throughout this specification to “an embodiment” or “the embodiment” means that a particular feature, structure or characteristic described in connection with that embodiment is included in at least one embodiment. Thus, the quoted phrases, or variations thereof, as recited throughout this specification are not necessarily all referring to the same embodiment.
Similarly, it should be appreciated that in the above description of embodiments, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure. This method of disclosure, however, is not to be interpreted as reflecting an intention that any claim require more features than those expressly recited in that claim. Rather, as the following claims reflect, inventive aspects lie in a combination of fewer than all features of any single foregoing disclosed embodiment. Thus, the claims following this Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment. This disclosure includes all permutations of the independent claims with their dependent claims.
Recitation in the claims of the term “first” with respect to a feature or element does not necessarily imply the existence of a second or additional such feature or element. Elements recited in means-plus-function format are intended to be construed in accordance with 35 U.S.C. § 112 ¶6. It will be apparent to those having skill in the art that changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention. Embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows.
