Patent Application
20160000158
The subject matter of this application is directed to a modular airbag system for personal protection, such as for increasing survival chances for skiers and snowboarders during an avalanche.
Personal airbag systems may deploy airbags near or next to a user's body, to provide buoyancy for the user in an avalanche, such that the user's body may be kept above the snow in an avalanche or near the top of the snow.
Personal airbag designs may traditionally be in the form of a single piece backpack. For instance, an exemplary personal airbag design is described in U.S. Patent Publication 2012/0060267 to Blenkarn et al., which is assigned on its face to Arc′Teryx Equipment Inc.
However, such airbags are very cumbersome and inflexible. For example, the user cannot strap on his/her own backpack while wearing the airbag backpack, because (1) strapping on two backpacks may be mechanically difficult or impossible to do and (2) strapping on a backpack on the airbag backpack may interfere with the normal function of the airbag, preventing the airbag from deploying the airbags properly.
Accordingly, there is a need for a modular airbag that can be used normally with a user's other equipment without sacrificing the airbag functions.
So that features of the present invention can be understood, a number of drawings are described below, It is to be noted, however, that the appended drawings illustrate only particular embodiments of the disclosure and are therefore not to be considered limiting of its scope, for the invention may encompass other equally effective embodiments.
Embodiments of the present invention may provide for a modular airbag.
In one embodiment as illustrated in
The side airbag compartments 120 may each contain one or more deflated airbags (not shown). The modular airbag 100 may contain one or more gas canisters (not shown) for inflating and deploying the airbags, in one or both of the side airbag compartments 120. The gas canisters may contain pressurized air or other gases, or may include chemicals that react upon trigger to produce gases, or may include mechanisms that pump gas into the airbags. The modular airbag 100 may further include a trigger for triggering the deployment of the airbags. The trigger may be manual and/or automatic, mechanical, chemical, and/or electrical.
The backpack straps 130 may be configurable in lengths, such that the modular airbag 100 can accommodate various different size backpacks, or even use without a backpack for the user.
In this configuration, the modular airbag 100 may be attached to a backpack, and the user may strap on the backpack as he/she would do normally. The modular airbag 100 may deploy the airbags on either side of the backpack, without interference from the backpack.
The modular airbag 100 may include one or more straps for attaching the modular airbag 100 to the user's body, for example, here a leg loop 140 is used to attach the lower portion of the modular airbag 100 to the user's leg. This allows the modular airbag 100 to be attached to the user's body, even if the backpack itself became detached from the user,
The modular airbag 100 may include additional straps to attach to the user's body, for example waist straps and/or shoulder straps (not shown).
For this configuration, the user may strap the modular airbag 200 onto his/her body, such that the main airbag compartment 220 is draped on his/her back. And then optionally, a backpack may be draped directly over the main airbag compartment 220 of the modular airbag 200. In this configuration, the main airbag compartment 220 may need to include a hardened frame to prevent the main airbag compartment 220 from collapsing under the weight of a backpack, which may interfere with the normal deployment of the side airbags 225 shown in
The modular airbag 200 may include airbag release trigger 210. The airbag release trigger 210 may be located on a shoulder strap 235, such that a user may conveniently reach it to trigger the airbag deployment.
The main airbag compartment 220 may have airbag release seams 250 on either side, such that when the side airbags 225 are released as shown in
As illustrated in
For this configuration, the user may strap the modular airbag 200 onto his/her body, such that the main airbag compartment 220 is draped on his/her back. And then optionally, a backpack may be draped directly over the main airbag compartment 220 of the modular airbag 200.
A modular airbag system 300 may include an airbag compartment, and at least one inflatable airbag 325 housed within the airbag compartment 320.
The inflatable airbag 325 may be configured to deploy (e.g., upward from a top side and/or outward from a vertical side) from a side of the airbag compartment 320. One or more straps may be connected to the airbag compartment 320 and configured to strap the airbag compartment 320 securely to an object (for example a backpack) on an outer surface of the object, and configured to release the airbag compartment 320 from the object.
A modular airbag system 400 may include an airbag compartment, and at least two inflatable airbags 425 housed within the airbag compartment 420.
The inflatable airbags 425 may be configured to deploy outward on either side of the airbag compartment 420, in two opposite horizontal directions. One or more straps may be connected to the airbag compartment 420 and configured to strap the airbag compartment 420 securely to an object (for example a backpack) on an outer surface of the object, and configured to release the airbag compartment 420 from the object.
Although the invention has been described above with reference to specific embodiments, the invention is not limited to the above embodiments and the specific configurations shown in the drawings. For example, some components shown may be combined with each other as one embodiment, or a component may be divided into several subcomponents, or any other known or available component may be added. Those skilled in the art will appreciate that the invention may be implemented in other ways without departing from the spirit and substantive features of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
