Various systems are used in applications, such as sports, motor vehicle operation, and the like, to help reduce injuries. For example, football players typically wear a football helmet and shoulder pads to minimize the risk of injury (e.g., due to collisions with other players, the ground, etc.) while playing. Similarly, motor vehicle operators such as motorcyclists often wear helmets to minimize the risk of injury (e.g., due to collisions with other motor vehicles, etc.) while driving.

The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
In the following detailed description, reference is made to the accompanying drawings, which form a part thereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
Referring to the figures generally, various embodiments disclosed herein relate to airbag deployment systems for users such as athletes, motor vehicle operators, and the like. The airbag deployment system generally includes a helmet (e.g., a head protection assembly such as a football helmet, hockey helmet, motorcycle helmet, etc.) and a torso protection assembly (e.g., football shoulder pads, a torso or shoulder member, etc.). Upon occurrence of a triggering event, such as detection of a potential or actual impact, an airbag is inflated and couples the helmet to the torso protection assembly. In some embodiments, deployment and inflation of an airbag occur together (e.g., the act of inflation deploys the airbag from the structure to which it is mounted or attached). In other embodiments, deployment occurs independently from inflation (e.g., a cover is first removed from the airbag, after which it is later inflated). In some embodiments, the airbag prevents or resists relative movement between the helmet and the torso protection assembly to, among other things, minimize accelerations experienced by the head and neck portions of the user and reduce the risk of the user experiencing a concussion or other undesirable injuries.

For example, in some embodiments, airbag connector 23 and torso protection assembly connector 18 both include one or more magnets configured to secure helmet 12 and torso protection assembly 14 together by way of a magnetic force. A series of magnets may extend partially or entirely around a circumference of a lower portion of airbag 25, and a corresponding number of magnets may extend partially or entirely around an upper portion of torso protection assembly 14. Upon contact, the magnets actively couple helmet 12 and torso protection assembly 14 in relative positions (e.g., the relative positions of the helmet and torso protection assembly at the time of (or just prior to) impact) to resist further relative movement.
In another embodiment, airbag connector 23 and torso protection assembly connector 18 both include one or more hook and loop fasteners configured to secure helmet 12 and torso protection assembly 14 together by way of a mechanical connection. Typically, the opposing surfaces to be fastened have differing connection strips, either hook connectors or loop connectors. When the two components are actively connected, the hooks catch in the loops and fasten the components together. A series of hook and loop fasteners may extend partially or entirely around a circumference of a lower portion of airbag 25, and a corresponding series of hook and loop fasteners may extend partially or entirely around an upper portion of torso protection assembly 14. Upon contact, the hook and loop fasteners actively couple helmet 12 and torso protection assembly 14 in relative positions to resist further relative movement.
In further embodiments, airbag connector 23 and torso protection assembly connector 18 may combine to secure helmet 12 and torso protection assembly 14 together by way of a connection through quick drying adhesives. When airbag 25 is deployed or inflated, adhesive components may be extruded from the surface, or may be exposed (e.g., by removing a protective covering) and extend partially or entirely around a circumference of a lower portion of airbag 25. The adhesive components may also be extruded from one or both components. Upon contact, the adhesive components actively couple helmet 12 and torso protection assembly 14 in relative positions to resist further relative movement. In some embodiments, the adhesive may be formed at the time of contact by the reaction of two separate components, one of which is disposed on connector 18 and the other on connector 23. In some embodiments, adhesives having varying strengths may be used about one or both of helmet 12 and torso protection assembly 14 to provide multiple joints of varying strength.
In some embodiments, one or both of connectors 18 and 23 may be configured to have one or more portions fail at predetermined threshold levels, thereby absorbing a portion of the energy involved in an impact. For example, one or both of connectors 18 and 23 may include components configured to fail (e.g., break, rupture, tear, etc.) at a predetermined torque level, a predetermined force level (e.g., a tensile force, a shear force, etc.), etc. In embodiments where multiple connector components are utilized, individual portions of connector 18 and/or 23 may be configured with varying failure strengths, such that the portions fail at varying threshold levels of torque, force, etc.
For example, in some embodiments connectors 18 and 23 include magnets configured to form a coupling joint capable of withstanding a certain predetermined force or torque. Once the predetermined force or torque is reached or exceeded, the coupling joint fails, such that the parts are decoupled. As noted above, multiple magnetic coupling joints may be formed, with varying degrees of force or torque being required to decouple each of the joints. Other types of connector components (e.g., adhesives, mechanical couplings, hook and loop fasteners, etc.) may be configured in a similar fashion to provide for joint failure and energy absorption during and after impact.

Processing circuit 74 is configured to control operation of airbag system 76. In one embodiment, processing circuit 74 controls operation of airbag system 76 based on sensor data from sensor system 72 and/or other inputs and data. For example, in some embodiments, stored data in memory 38 and measured data from sensor 40 may be compared to determine an impact parameter threshold (e.g., a user defined threshold) has been reached. If so, processor 36 inflates helmet airbag assembly 16. Processor 36 controls the inflation of the airbag assembly through inflation device 19, leading to the connection of helmet 12 and torso protection assembly 14.
In one embodiment, processing circuit 74 includes processor 36 and memory 38. Processor 36 may be implemented as a general-purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a digital-signal-processor (DSP), a group of processing components, or other suitable electronic processing components. Memory 38 is one or more devices (e.g., RAM, ROM, Flash Memory, hard disk storage, etc.) for storing data and/or computer code for facilitating the various processes described herein. Memory 38 may be or include non-transient volatile memory or non-volatile memory. Memory 38 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described herein. Memory 38 may be communicably connected to processor 36 and provide computer code or instructions to processor 36 for executing the processes described herein.
In one embodiment, helmet airbag assembly 16 may be triggered based on at least one of sensor data from sensor system 72 and a manual user input (i.e., self-triggered). The sensor data may indicate at least one of a potential impact and an actual impact. Helmet airbag assembly 16 may be triggered (i.e., inflating airbag 25) by processor 36 through the activation of inflation device 19 based on sensor data exceeding a predetermined threshold (e.g., threshold data stored in memory 38). The predetermined threshold may be set by a user and/or based on or set using other factors (e.g., known player size, etc.). Airbag 25 may be deployed from the underside of helmet 12 toward torso protection assembly 14. Airbag 25 may also be deployed about a portion of the user's neck including about the side of the user's neck and/or about the posterior portions of the user's neck. In another embodiment, an airbag may also be deployed from face mask 13 about the front portion of the user's neck. In one embodiment, processing circuit 74 is configured to inflate the airbag assembly prior to impact based on expected impact data such as time to impact, relative velocity, predicted impact strength or location, etc. In other embodiments, processing circuit 74 is configured to inflate the airbag assembly after impact based on actual impact data. As noted elsewhere herein, processing circuit 74 may further base inflation of the airbag assembly on other factors, such as player characteristics (e.g., height, weight, current speed or direction, etc.), pre-defined parameters (e.g., location on a playing field, location on street etc.), and the like.

In yet another embodiment, as shown in
After coupling helmet 12 and torso protection assembly 14, additional data is analyzed regarding user defined thresholds (57). For example, the user may store data in memory 38 which processor 36 may access to determine if the impact is of sufficient magnitude to require the decoupling of the joint(s). The coupling between two connectors may form a single coupling joint configured to fail upon application of a predetermined load to the coupling joint to aid in the dissipation of impact energy. The connectors may however form a plurality of coupling joints where each coupling joint is configured to fail upon application of a different load to its respective coupling joint. If a threshold is not exceeded, the coupling may remain intact (58). If a threshold is in fact exceeded, all or individual joints may be allowed to fail (59) in order to better dissipate impact energy. For example, if the active coupling of a joint is provided through the implementation of magnets, an individual joint may be designed to withstand a certain impact. This impact threshold may be different for the various locations around the user's neck. Thus, different strength magnets (or, similarly, fasteners, adhesives, etc.) may be implemented for the various joints to allow for the decoupling of an individual joint which encounters an impact exceeding its respective design strength.
