The present disclosure is generally concerned with safety systems for use by snow sports participants and others. More specifically, at least some of the disclosed embodiments are concerned with a backpack-integrated whole-body airbag system, including wearable inflatable lower body/lower extremity garments to provide whole-body flotation during avalanche incidents and/or potentially catastrophic high-impact crashes.
Many outdoor activities, sports, recreations and pastimes pose inherent risks and dangers, especially while participating in such activities in avalanche-prone areas. In particular, snow sports enthusiasts and those engaged in mountaineering, that is, endeavors such as mountain hiking and climbing, face the real dangers of becoming involved in an avalanche incident and/or high-impact crashes.
In the more recent past, there has been a significant increase in participation in sports and recreational activities in avalanche-prone areas as well as other venues where high-impact crashes can occur. In an attempt to attenuate the inherent risks of such activities, participants dedicate considerable efforts to minimize such risks and avail themselves of various risk-mitigating avalanche protective equipment, including: mechanical gear such as avalanche shovels, portable collapsible probes; avalanche transceivers such as beacons; Avalung air filtration systems; and, RECCO® rescue system reflectors.
In addition to these items, back-pack avalanche airbag systems have become increasingly prominent. These airbag systems use either compressed air released from cartridges contained in the backpack apparatus, or are inflated with ambient air by an electric fan, to inflate an airbag which is released from the backpack apparatus and surround the upper portion of the body of the wearer.
The deployed airbag provides 2 functions: it may help the wearer to stay afloat atop the cascading avalanche debris by utilizing the buoyancy factor of the airbag (see
Usage of airbags, particularly in the backcountry and on off-piste terrain, has increased dramatically primarily because of perceived effectiveness. Industry reports tout extraordinary initial survival rates upwards of 97%. However, the ultimate long-term survival rates are much lower, around 50%. Among the most likely reasons for this disparity is that victims who survive the initial avalanche or other traumatic event may later succumb to an immense degree of polytrauma to the lower abdominal/pelvic region, lower torso and lower extremities, including osseous and soft-tissue trauma (i.e., ligaments, tendons, muscles, internal hemorrhaging) from which the victims cannot recover. However, little to no emphasis has been placed on protection of the lower body of a user, or on systems for providing such protection.
It should be noted that the embodiments disclosed herein do not constitute an exhaustive summary of all possible embodiments, nor does this brief summary constitute an exhaustive list of all aspects of any particular embodiment(s). Rather, this brief summary simply presents selected aspects of some example embodiments. It should further be noted that nothing herein should be construed as constituting an essential or indispensable element of any invention or embodiment. Rather, various aspects of the disclosed embodiments may be combined in a variety of ways so as to define yet further embodiments. Such further embodiments are considered as being within the scope of this disclosure. As well, none of the embodiments embraced within the scope of this disclosure should be construed as resolving, or being limited to the resolution of, any particular problem(s). Nor should such embodiments be construed to implement, or be limited to implementation of, any particular technical effect(s) or solution(s).
In general, disclosed embodiments are concerned with a whole-body airbag system that may provide consistent protection not just to the caput, shoulders and upper torso, but comprehensive protection to the entire body, including the lower torso, pelvic region and lower extremities. This is accomplished by way of a selectively inflatable lower body garment that, depending upon the embodiment, may or may not, be integrated together with an upper body protection/flotation system. Such embodiments may optimize short and long-term survivability in avalanche situations, high-impact falls, or other traumatic events.
Example embodiments of the invention may provide any one or more of the various features and elements disclosed herein. Such features and elements include, but are not limited, those discussed immediately below.
The disclosed whole-body airbag system may be configured in a variety of ways and configurations (as disclosed in
1. airbag deployment system contained in an internal compartment within a dedicated backpack;
2. airbag inflating system configured to provide sufficient simultaneous deployment of the main airbag for the caput, neck, shoulders and upper torso, as well as internal bifurcated tubing that would exit the bottom/lateral aspects of the backpack;
3. lower body garment made from any one or more of a variety of textiles and materials, with separate airbag compartments on the lateral and/or medial aspects of the lower extremities above and below the knee;
4. integrated tubing within the lower-body garment to deliver air simultaneously to each separate compartment, with such tubing connecting to the backpack tubing using any type of quick connect/disconnect connections such as, for example, quick-connect hose fittings;
5. manual deployment system utilizing a mechanical draw cord approach or comparable system/device, such as an actuating push button, positioned within the whole-body inflatable airbag system for easy access by the wearer;
6. automatic deployment system utilizing appropriate accident detection/sensing technologies (e.g., motion sensors, spatial orientation sensors, directional velocity sensors, angular velocity sensors (i.e., gyrometer sensors), rotation sensors, shock sensors, collision sensors, accelerometers, etc.);
7. threshold parameters for automatic deployment of the airbag system will be determined and programmed into a processor that is integrated in the airbag system;
8. automatic deployment of the airbag system can also be effected by rapid separation of the rider from the vehicle upon which the user is riding (e.g., skis, snowboard or snowmobile), with such a tethering mechanism automatically signaling the actuator to deploy the airbag system;
9. all, or any of the above, accident detection/sensing or any other technologies known by one of skill in the art may be housed in the sensory unit housed within any portion of the backpack;
10. the airbag-containing garments will allow deployment of each separate airbag through a lateral window or slit secured via a common hook-and-loop fastener (e.g., Velcro®), such that each deployed airbag can be subsequently refitted for future use;
11. manual or automatic deployment of the whole-body airbag system may be integrated with a manual or automatic emergency alerting system (e.g., AvR Alert System™) to communicate with avalanche search and rescue teams, ski patrol and/or other emergency responders the precise location of the victim using a current global positioning system (GPS) or similar technologies;
12. embodiments of the invention may include a wireless activation feature—for example, a wearable activation device may be attached to clothing, gloves, a helmet or independently to the wearer, for example, that is operable to wirelessly activate the airbag deployment system, such as by a communication system conforming to the Bluetooth or other short range communication protocols, the whole-body airbag system;
13. one or more inflating systems operable to inflate some or all compartments of the airbag system by a fan, compressed gas, or both, or any other mechanism(s) of comparable functionality—where a fan or fans are used, the whole-body airbag system may be deployed repeatedly during a single outing;
14. one or more of the airbags may be configured in a modular fashion so that they can be readily removed and replaced, on an individual basis, if/when needed;
15. embodiments may provide a degree of protection against hypothermia—particularly, because one or more portions of the whole-body airbag system may be configured and arranged so that the system may prevent or reduce, when deployed, direct contact between a portion of the body of the user and the snow, heat transfer from the user to the snow/environment may be relatively less than would be the case if the user were in direct contact with the snow to illustrate, an inflated bag such as those disclosed herein is a poor conductor of heat, so that placement of such an inflated bag between the user and the snow will tend to reduce the rate of heat transfer from the user to the surrounding environment which may comprise snow and/or exposure to the atmosphere;
16. the airbag(s) of the lower body garment, in combination with an inflatable air bag in a backpack or similar configuration, provides additional flotation capability, in the event of an avalanche, beyond what a backpack airbag might solely provide; and
17. separately from, or in addition to, the lower-body garment, one or more additional airbags and associated compartments may be provided that may be connected, releasably or permanently, to a bottom portion within, or external to, a backpack, which may or may not include its own airbag(s), so that the additional airbags may provide protection to the rear and lateral aspects of the lower body and lower extremities portions of the user such additional airbags may extend down as far as the inferior-most portions of the lower extremities of the user and up to the middle portion of the back of the user. The additional airbags may be contained within and released from the backpack or attached to the backpack with straps, buckles, clips, or other suitable devices. The additional airbags would be released, activated and inflated simultaneously by the airbag deployment system.
The appended drawings contain figures of some example embodiments to further explain various aspects of the present disclosure. It will be appreciated that these drawings depict only some embodiments of the disclosure and are not intended to limit its scope in any way. The disclosure will be described and explained with additional specificity and detail through the use of the accompanying drawings.
The present disclosure is generally concerned with systems and devices designed to enhance long-term survivability while participating in activities in avalanche-prone venues (for example, alpine downhill skiing, snowboarding, snowmobiling, and mountaineering), and in activities posing a risk for high-impact crashes.
As noted, current technologies intended to provide protection for avalanche/high-impact crash survival, including current versions of the avalanche airbag systems, do not offer genuine long-term survivability.
Accordingly, in order to provide enthusiasts engaged in outdoor activities in avalanche-prone venues (where such activities may include, but are not limited to, downhill skiing, snowboarding, snowmobiling, and mountaineering) with greater potential for true long-term survival beyond the immediate period of avalanche involvement or high-impact fall, embodiments of the invention embrace, among other things, an apparatus comprising a specialized wearable pneumatic lower body garment (which may be referred to herein as ‘avypants’) integrated with an upper-body avalanche airbag flotation system to provide whole-body protection during avalanche involvement, increase whole-body buoyancy and flotation above the careening avalanche, thereby decreasing whole-body injuries, and thus increasing long-term avalanche/crash survivability and maximizing recovery of pre-incident quality of life.
Various materials can be used in the construction of the disclosed embodiments. For soft and flexible elements of such embodiments, such as the airbags, clothing pieces, backpacks, and other garments, materials that can be used include, but are not limited to, any combination of textiles, plastic in sheet or other forms, and rubber. Tubing, such as that used to convey gas to an inflatable bladder or bag, can made of rubber, plastic, silicone, and/or other suitable materials. In some embodiments at least, the tubing is crush-resistant. Where metal is employed in an embodiment, such metal may be a metal or metals, including alloys, that is relatively light and strong, such as, but not limited to, titanium or aluminum, for example. As well, some embodiments may employ composite materials including, but not limited to, carbon-based composites or fiberglass composites, wherever relatively light weight, strength, and some degree of stiffness, are needed in a component of an embodiment.
It should be noted that while example embodiments are referred to as including “airbags” and using “air” (which refers to atmospheric air), the scope of the invention is not so limited. Rather, and more broadly, any non-explosive and non-toxic gas(es) or combinations of gases, including inert gases such as nitrogen for example, may be used in various embodiments of the invention for the purpose of inflating one or more airbags.
As indicated in
With reference now to
It is noted that any of the avybag airbag compartments included in garments or backpacks disclosed herein may be closed with a suitable closure that is adequate to retain the airbag in the compartment, but which will not impede a deployment of the airbag. One example of such a closure is a hook-and-loop type of closure, but any other closure, such as snaps for example, that will perform the aforementioned functionalities may alternatively be employed. The closure may, or may not, run a majority of a length of the opening to the compartment. Also, the disclosed airbags may be made of any suitable material, examples of which include, nylon, nylon coated with plastic or rubber, plastic, rubber, composite materials, mylar, as well as any flexible reinforced materials, where such reinforcing may take the form of rip-stop or other fabrics, or any combination of the foregoing. In general, the airbag material may be sufficiently strong and flexible to withstand inflation forces, while also maintaining an inflated state when deployed. The airbag material may be water-resistant, or waterproof.

It is noted that while the discussion thus far has primarily been directed to lower-body garments, such as pants for example, such garments are presented only by way of example, and the scope of the invention embraces other garments as well. By way of illustration, some embodiments additionally, or alternatively, include an upper-body garment, such as a jacket for example, that includes one or more inflatable airbags connected, and/or connectible, to an airbag inflation system such as the airbag inflation system 104. In still other embodiments, the garment that includes one or more airbags is a single-piece suit that includes an upper-body garment and lower-body garment that are integrated together with each other. More generally, embodiments of the invention can include any garment or other wearable item within which one or more airbags can be included.

One mode of operation that can be employed to trigger airbag inflation is a manual mode. As used herein, a manual actuation is any actuation that requires some type of affirmative input by the user. One example of manual actuation system and operation is a handle attached to a cable or other device that is in turn connected to a gas cylinder for example. In operation, a user can pull the handle, which may be located on the front of the torso of the user, causing the release of compressed gas from the gas cylinder to one or more airbags. Another example of a manual actuation system and operation is a voice-actuated device which, upon detecting the voice of the user, can cause, in conjunction with a control circuit, the release of compressed gas from the gas cylinder to one or more airbags. Still another example of a manual actuation system is a pushbutton that a user can squeeze or depress to cause, either in conjunction with a control circuit or not, the release of compressed gas from the gas cylinder to one or more airbags.
Another mode of operation that can be employed to trigger airbag inflation is an automatic mode. As used herein, an automatic actuation of the airbag inflating system is any actuation that is performed without affirmative action or input by the user. The automatic inflation of one or more airbags can be performed based on input received by one or more sensors of a control system. The control system can be configured to initiate inflation in a variety of scenarios, such as a falling scenario, burial scenario, and sudden acceleration/deceleration scenarios.
In the falling scenario for example, one or more accelerometers and/or position-sensing devices can be provided that predict an impending high-impact crash by sensing speed and/or multi-axis movement of the person wearing the airbag inflating system. In an avalanche burial scenario, for example, one or more pressure sensors, examples of which are disclosed in one or more of the Related Applications, detect gradual and/or sudden increases in pressure on the body of a user. Such sensors (which may be zeroed at atmospheric pressure, or any other pressure or range of pressures) can thus detect situations in which snow and/or debris are being piled on top of and/or around a user. These pressure sensors, and any other sensors disclosed herein, can be integrated into clothing and/or equipment so as to be distributed at various locations on the body of the user. In one particular example, multiple pressure sensors are centripetally arranged on the body of the user.
As another example, an audio sensor can be used as a basis to trigger inflation of one or more airbags when ambient noise begins to quickly decrease, as could occur in a burial scenario when the user is buried under snow and debris. Further, these, or other audio sensors can also be configured to trigger inflation when ambient noise begins to rapidly increase, as can occur when an avalanche has started.
It will be appreciated that various other scenarios can be addressed, through the use of appropriate sensors and combinations of sensors in embodiments of the invention. As well, any given embodiment can be configured with a variety of different sensors that individually and/or collectively are configured to address one or more scenarios that may potentially be experienced by a user.
