With reference to the Figures, wherein like numerals indicate like parts throughout the several views, an apparatus 10 for a vehicle 12 includes a stowage bin 14 defining a compartment 16 and an airbag 18 mounted to the stowage bin 14. The airbag 18 is deployable to an inflated position. When the airbag 18 is in the inflated position, the airbag 18 at least partially encloses the compartment 16.
The compartment 16 is easily accessible by occupants of the vehicle 12 to place and retrieve items, such as luggage, bags, entertainment devices, vehicle-maintenance devices, etc. In the event of a sudden deceleration of a vehicle, e.g. a vehicle impact, roll over, hard braking, pre-collision activation, etc., the airbag 18 is inflatable to at least partially enclose the compartment 16 of the stowage bin 14 to retain any items, such as luggage, baggage, travel items, vehicle maintenance items, etc., in the compartment 16.
With reference to
The vehicle 12 includes a body 20. The body 20 defines a passenger compartment 22 to house occupants, if any, and other components of the apparatus 10. The body 20 includes a floor 24 disposed at the bottom of the passenger compartment 22.
The vehicle 12 may include one or more seats 26 in the passenger compartment 22. The vehicle 12 may include any suitable number of seats 26 in any suitable position, e.g., front seats, back seats, left side, right side, etc. The position and orientation of the seats 26 and components thereof may be adjustable.
With continued reference to
As shown in
The apparatus 10 may include a pressure sensor that detects the presence of items in the compartment 16 of the stowage bin 14. Specifically, the pressure sensor may be configured to be triggered by the weight of the items, in which case the pressure sensor generates a signal indicating items are present in the compartment 16. The pressure sensor may be below the compartment 16. The pressure sensor may be supported by the stowage bin 14 and/or the floor 24. For example, the pressure sensor may be fixed to the stowage bin 14, e.g., at the bottom 32. In another example, the pressure sensor may be fixed to the floor 24 with the compartment 16 of the stowage bin 14 above the pressure sensor, i.e., the pressure sensor is between the compartment 16 of the stowage bin 14 and the floor 24.
The apparatus 10 includes an airbag assembly 34 that includes the airbag 18 and an inflator 36. The airbag assembly 34 may be mounted to one of the walls 30 of the stowage bin 14. The airbag assembly 34 may be mounted to the upper lip 28 of the stowage bin 14. In such an example, the airbag 18 may inflate over the compartment 16, i.e., the entire compartment 16 may be below the airbag 18 when inflated. In another example, the airbag assembly 34 may be mounted to the wall 30 at a position spaced from the upper lip 28, i.e., below the upper lip 28.
The airbag assembly 34 may be mounted to the stowage bin 14 between the seats 26 and the compartment 16 of the stowage bin 14. For example, the airbag assembly 34 may be mounted to one of the walls 30 disposed between the compartment 16 and the seat 26. In the example where the stowage bin 14 is vehicle-forward of the seat 26 (e.g., a front seat), the airbag assembly 34 may be mounted to the wall 30 that is vehicle-rearward of the compartment 16.
As shown in
The airbag 18 inflates away from the wall 30 of the stowage bin 14 to which the airbag 18 assembly is mounted. In the example shown in
As shown in
The airbag 18 may be a woven polymer or any other material. As one example, the airbag 18 may be woven nylon yarn, for example, nylon 6-6. Other examples include polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyester, etc. The woven polymer may include a coating, such as silicone, neoprene, urethane, etc. For example, the coating may be polyorgano siloxane.
The inflator 36 is in fluid communication with the airbag 18. Upon receiving a signal, the inflator 36 may inflate the airbag 18 with an inflatable medium. As one example, the inflator 36 may be a pyrotechnic inflator. Upon receiving a signal from, e.g., the vehicle computer, the inflator 36 may inflate the airbag 18 with an inflatable medium, such as a gas. In examples where the inflator 36 is a pyrotechnic inflator, the inflator 36 uses a chemical reaction to drive inflation medium to the airbag 18. The pyrotechnic inflator may be of any suitable type, for example, a cold-gas inflator. As another example, the inflator 36 may include, for example, a canister of pressurized fluid. In such an example, the inflator 36 may include a releasable valve for selectively releasing the pressurized fluid from the canister to the inflation chamber 38. The releasable valve may be electronically releasable, pyrotechnically releasable, etc. Upon receiving a signal from, e.g., the vehicle computer, the valve may open to inflate the inflation chamber 38 of the airbag 18. The pressurized fluid may be any suitable fluid and may be in a gaseous state when inflating the inflation chamber 38 of the airbag 18.
At least part of the airbag assembly 34 may be removably mounted to the stowage bin 14. Specifically, inflator 36 may be removably mounted to the stowage bin 14. In other words, the inflator 36 may be removed from the stowage bin 14 and replaced while maintaining the integrity of the stowage bin 14, i.e., so the storage bin is reusable. The inflator 36 may be removably mounted to the stowage bin 14 with, for example, threaded fasteners. The inflator 36 may be removable and replaceable by, for example, a service technician.
In the example where the inflator 36 is a pyrotechnic inflator, the inflator 36 and the airbag 18 may be removable from the storage bin as a unit. In other words, the inflator 36 may be disconnected from the stowage bin 14 to remove both the inflator 36 and the airbag 18 from the stowage bin 14 for replacement. As another example, the inflator 36 may be removable from the rest of the airbag assembly 34 for replacement or recharge. In examples in which the inflator 36 includes a canister of pressurized fluid, the canister may be disconnected from the rest of the airbag assembly 34 for replacement or discharge, i.e., a new or recharged canister may be re-connected to the rest of the airbag assembly 34. In such examples, the canister is removably connected to the rest of the airbag assembly 34, e.g., by threaded connection.
The airbag assembly 34 may include an inflator cover 42 removably connected to the stowage bin 14 for service or replacement of the inflator 36. The inflator cover 42 may have a class-A surface, i.e., a surface specifically manufactured to have a high-quality, finished aesthetic appearance free of blemishes.
In examples where the inflator 36 is removable from the rest of the airbag assembly 34, the airbag 18 may be reusable. In such examples, the airbag 18 may be re-folded, rolled, etc., for reuse. For example, the airbag assembly 34 may include a cover 60 that removably attaches to the stowage bin 14 to conceal the airbag 18. In the event of an sudden deceleration, the cover 60 detaches from the stowage bin 14, i.e., under forces from the inflation of the airbag 18, to allow the airbag 18 to inflate across compartment 16. The cover 60 may be re-usable, i.e., reconnected to the stowage bin 14 after release. For example, the cover 60 and/or the stowage bin 14 may include clips or other releasable fasteners that releasably connect the cover 60 to the stowage bin 14 for reconnecting the cover 60 to the stowage bin 14. The cover 60 may have a class-A surface, i.e., a surface specifically manufactured to have a high-quality, finished aesthetic appearance free of blemishes.
The vehicle 12 may include a sensor. In the event of an sudden deceleration, the sensor may detect the sudden deceleration and transmit a signal through a communications network to the computer. The computer may transmit a signal through the communications network to the inflator 36. The sensor may be an impact sensor, accelerometer, etc.
The apparatus 10 includes an external tether 44 extending from the airbag 18 to the stowage bin 14. When the airbag 18 is in the inflated position, the external tether 44 positions the airbag 18 to enclose the compartment 16 of the storage bin, i.e., to retain items in the bin in the event of a sudden deceleration. When the airbag 18 is in the inflated position, the external tether 44 will exert a force on the airbag 18, retaining any items in the bin. As the airbag 18 deploys from the uninflated position to the inflated position, the airbag 18 may deploy upwardly from the compartment 16 with the external tethers 44 pulling the airbag 18 downwardly to retain any items in the stowage bin 14, e.g., the airbag 18 may move in an arced pattern to the inflated position to increase the likelihood of going over the items in the compartment 16 to retain the items in the compartment 16. The apparatus 10 may include any suitable number of external tethers 44. In the examples shown in
