## Title
Modular airbag system for personal protection

## Abstract

A modular airbag system may include at least one inflatable airbag configured to deploy outward on a side(s) of the airbag system, for example, in two opposite substantially horizontal directions, at least one airbag compartment, and one or more straps configured to strap the modular airbag system securely to one of a user's body and/or an object, and configured to release the modular airbag system from one of the user's body and/or the object.

## Background
BACKGROUND
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.

DETAILED DESCRIPTION
Embodiments of the present invention may provide for a modular airbag.
In one embodiment as illustrated in FIG. 1, a modular airbag 100 may include two side airbag compartments 120 with a plurality of backpack straps 130. The backpack straps 130 may be configured to allow the side airbag compartments 120 to be securely attached to a backpack and may be configured to allow the side airbag compartments 120 to be released or detached from the backpack. The side airbag compartments 120 may be configured to be attached on the two sides of the backpack.
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).
FIGS. 2A and 2B illustrate an exemplary airbag according to an embodiment of the present invention.
FIG. 2A illustrates an exemplary airbag 200 according to an embodiment. The modular airbag 200 may include a single main airbag compartment 220 and one or more body straps 230, for attaching the modular airbag 200 to the user's body. Here, body strap 230 is shown as a waist strap. There may also be shoulder straps 235 and chest 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 FIG. 2B.
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 FIG. 2B, the side airbags emerge and deploy from the opening created along the airbag release seams 250. The shapes of the side airbags 225 are not necessarily limited to any specific shape. However, some shapes of the side airbags 225 may be more optimal for deployment and/or buoyancy.
FIG. 3 illustrates a see-through view of the exemplary modular airbag 200 according to an embodiment of the present invention.
As illustrated in FIG. 3, the modular airbag 200 may contain (within the main airbag compartment 220) a gas canister 227, which can be triggered the airbag release trigger 210. Shoulder straps 235 may be draped over the user's shoulders. Shoulder straps 235 may include additional straps to attach the shoulder straps 235 to the shoulder straps of a backpack. Body straps 230 may further securely attach the modular airbag 200 to the user's body. The main airbag compartment 220 may include two or more side airbags, configured to deploy outward on the either sides of the main airbag compartment 220, in the two opposite horizontal directions.
FIG. 4 illustrates a side view of an user fitted with an exemplary modular airbag 200 and a backpack, according to an embodiment of the present invention.
