Definitions
- the present invention relates to a vehicle restraint system which comprises an airbag into which an inflator can assembly may be placed.
- the inventive airbag preferably comprises two body panels, attached by one substantially straight seam, and a separator panel which, upon folding and attaching of the two body panel sections of the airbag produces a mouth (looped pocket) for holding of the above-mentioned inflator can assembly.
- Such an article allows for quick and complete inflation upon release of propellant and facilitates packing in a standard restraint system enclosure.
- the invention thus encompasses both the restraint system and the airbag itself.
- Inflatable protective cushions used in passenger vehicles are a component of relatively complex passive restraint systems.
- the main elements of these systems are: an impact sensing system, an ignition system, a propellant material, an attachment device, a system enclosure, and an inflatable protective cushion.
- the propellant Upon sensing an impact, the propellant is ignited causing an explosive release of gases filing the cushion to a deployed state which can absorb the impact of the forward movement of a body and dissipate its energy by means of rapid venting of the gas.
- the entire sequence of events occurs within about 30 milliseconds.
- the cushion In the undeployed state, the cushion is stored in or near the steering column, the dashboard, in a door, or in the back of a front seat placing the cushion in close proximity to the person or object it is to protect.
- Inflatable cushion systems commonly referred to as air bag systems have been used in the past to protect both the operator of the vehicle and passengers.
- Systems for the protection of the vehicle operator have typically been mounted in the steering column of the vehicle and have utilized cushion constructions directly deployable towards the driver.
- These driver-side cushions are typically of a relatively simple configuration in that they function over a fairly small well-defined area between the driver and the steering column.
- One such configuration is disclosed in U.S. Patent
- Inflatable cushions for use in the protection of passengers against frontal or side impacts must generally have a more complex configuration since the position of a vehicle passenger may not be well defined and greater distance may exist between the passenger and the surface of the vehicle against which that passenger might be thrown in the event of a collision.
- Prior cushions for use in such environments are disclosed in U.S. Patent 5,520,416 to Bishop, issued May 28, 1996; U. S. Patent 5,454,594 to Krickl issued October 3, 1995; U.S. Patent 5,423,273 to Hawthorn et al. issued June 13, 1995; U.S. Patent 5,316,337 to Yamaji et al. issued May 31, 1994; U.S. Patent 5,310,216 to Wehner et al. issued May 10, 1994; U.S.
- the permeability of the cushion structure is an important factor in determining the rate of inflation and subsequent rapid deflation following the impact event.
- the use of several fabric panels in construction of the cushion may prove to be a useful design feature .
- the use of multiple fabric panels in the cushion structure also permits the development of relatively complex three dimensional geometries which may be of benefit in the formation of cushions for passenger side applications wherein a full bodied cushion is desired. While the use of multiple fabric panels provides several advantages in terms of permeability manipulation and geometric design, the use of multiple fabric panels for use in passenger side restraint cushions has historically required the assembly of panels having multiple different geometries involving multiple curved seams. As will be appreciated, an important consideration in cutting panel structures from a base material is the ability to maximize the number of panels which can be cut from a fixed area through close-packed nesting of the panels.
- current vehicle restraint systems comprise an airbag which is attached, through a fastening or adhesive means, to an inflator can.
- the standard vehicle restraint system itself generally comprises an inflator can retainer, an inflator can, a housing (in the inflator can is disposed), a folded airbag attached, as noted above, to the housing, an airbag retainer to prevent release of the airbag, and an airbag door.
- the components parts, the manpower needed to assemble the system, and the extra parts required to properly store the airbag all add up to substantial cost for the consumer.
- the present invention provides a vehicle restraint system which comprises an airbag and an inflator can assembly, whereby the inflator can of such an assembly is disposed within the airbag itself, rather than attached by adhesives, staples, and the like.
- the particularly preferred airbag configuration may be constructed from two mirror-image body panel sections and one rectilinear center panel section. Upon folding and contacting of the corresponding areas of each of the body panel sections, the sections are connected to one another and to the center panel section by a series of flat, straight seams.
- the airbag configuration formed according to the present invention results in highly efficient utilization of materials and may be constructed substantially without the need for complex curved seaming operations. As such, the present invention constitutes a useful advancement over the present art.
- the rectilinear panel thus forms a looped pocket into which the inflator can, comprising the inflator itself, is disposed.
- the housing of the system surround the looped pocket of the airbag while the inflator can and inflator fit inside both the airbag and the housing simultaneously.
- vehicle restraint system is intended to mean both inflatable occupant restraining cushion and the mechanical and chemical components (such as the inflation means, ignition means, propellant, and the like). It is a more particular object of the present invention to provide a vehicle restraint system wherein the inflator can is disposed within the airbag. It is a further object of the present invention to provide an airbag manufactured from mirror-image panel sections separated by a rectilinear section which, upon folding and contacting of the corresponding mirror-image areas of the two sections, the sections are connected to one another by a series of substantially straight, flat seams.
- the present invention provides an airbag cushion for use in a vehicle restraint system, which comprises a looped pocket for introduction of the inflator can of an inflator assembly.
- a looped pocket for introduction of the inflator can of an inflator assembly.
- the most preferred embodiment includes two mirror-image body panel sections two substantially straight seams along corresponding lateral boundary edges.
- the boundary segments of the body panels which are not joined to one another are joined around the perimeter of a rectilinear center panel by a series of substantially straight seams thereby forming a looped pocket in the airbag as well as an overall inflatable cushion structure.
- the airbag itself need not be created from two mirror- image body panel sections as any configuration of fabric panels will function properly in this invention as long as a three- dimensional inflatable cushion is formed and a looped pocket is created in the airbag in which the at least the inflator can of an inflator assembly is disposed. Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice for the invention. It is to be understood that both the foregoing general description and the following detailed description of preferred embodiments are exemplary and explanatory only, and are not to be viewed as in any way restricting the scope of the invention as set forth in the claims.
- FIG. 1 illustrates an aerial perspective view of the airbag of the present invention prior to folding and seaming
- FIG. 2 is a front perspective view of the folded and seamed inventive airbag after inflation
- the term "front' is intended to mean that portion of the airbag which is intended to be impacted by a person or object to be protected;
- FIG. 3 illustrates an aerial perspective of one body panel section of a multi- piece airbag of the present invention prior to folding and seaming;
- FIG. 4 illustrates an aerial perspective of a center panel section of a multi-piece airbag of the present invention prior to seaming
- FIG. 5 illustrates a front perspective view of the folded and seamed inventive airbag comprising the sections of FIGs. 3 and 4 after inflation
- FIG. 6 illustrates one embodiment of the inventive vehicle restraint system including the disposition of the inflator assembly within the inflated airbag.
- FIG. 1 there is shown an unfolded and unseamed inflatable restraint cushion (airbag) 2.
- this unfolded and unseamed inflatable restraint cushion 2 includes a first body panel section 10 and a second body panel section 12 which are mirror images of each other.
- these body panel sections 10, 12 are not required to be of the same shape and configuration. However, it has proven more cost effective to cut the body panel sections 10, 12 as two separate pieces and attaching them to each other through the use of a substantially straight seam.
- the body panel sections 10, 12 (or the larger panel section in the alternative embodiments) are altered to fit the entire width of the fabric in order to provide the most efficient use of the fabric itself.
- Attached to the end of these body panel sections 10, 12 are two end panels 14, 16, which are also mirror images of each other. As with the body panel sections 10, 12, these end panels 14, 16 may be of any configuration or shape in alternative embodiments. Furthermore, the end panels 14, 16 may also be omitted in order for a one-piece airbag (such as in FIG. 6) to be utilized. Separating the two body panel sections 10, 12 is a rectilinear separator panel section 18.
- this rectilinear panel 18 will form a looped pocket 42 of FIG. 3 to permit disposition of the inflator can assembly 44, 46, 48 of FIG. 3.
- This separator panel 18 may be of any shape which ultimately provides a looped pocket configuration in the airbag 2 upon folding and seaming of at least the two body panel sections 10, 12.
- this separator panel 18 preferably, though not necessarily, comprises a means for permitting inflator can of differing sizes to be placed therein.
- rectilinear slits 23 are cut into the separator panel at a position equidistant from the body panel sections 10, 12 which run parallel to the short sides of the separator panel 18.
- FIG. 2 there is illustrated a potentially preferred singular seaming arrangement for use in establishing the connective relationship between the body panel section 10 and the other 12 as well as the end panel 14 to the other 16.
- the body panel sections 10, 12 as well as the end panels 14, 16 are connected to one another by means of a substantially straight body seam 24.
- Such a single seam 24 provides a simplified manner of producing such airbags, particularly in large-scale sewing operations. While only one such body seam 26 is illustrated in FIG. 2 it is to be understood that in the preferred embodiment an identical seam is likewise disposed along the length of the body panel sections 10, 12 on the opposite side of the airbag 2.
- Alternative embodiments include those which utilize any number of seams to connect the panel sections 10, 12 to one another.
- seams or seaming operations include not only traditional sewn seams but also by way of example only and not limitation, interwoven seams, adhesive seams, melt bonded seams, ultrasonic seams, and other suitable attachment methods as may be known to those of skill in the art.
- interwoven seams such as interwoven seams, adhesive seams, melt bonded seams, ultrasonic seams, and other suitable attachment methods as may be known to those of skill in the art.
- adhesive seams such as may be known to those of skill in the art.
- melt bonded seams such as may be known to those of skill in the art.
- ultrasonic seams such as may be known to those of skill in the art.
- FIGs. 3 and 4 illustrate a preferred multi-piece airbag configuration for the inventive restraint system.
- FIG. 3 is a depiction of one body panel section 26 (at least two of such panel sections are needed to form an airbag) which includes a centrally disposed section 27 which, upon attachment to its corresponding section on a second body panel section forms a looped pocket for introduction and storage of an inflator can assembly (not illustrated).
- Lines 29 show the folding and seaming points for this first body panel section 26 to a second mirror-image body panel section (not illustrated).
- a center panel section 28 (FIG. 4) is utilized in combination with the two body panel sections 26 to form the airbag 3 (FIG. 5).
- FIG. 5 depicts the airbag 3 after seaming and inflation.
- the center panel 28 is attached by substantially straight seams 25 to the two body panel sections 26.
- the two body panel sections are also attached to each other by substantially straight seams 29.
- FIG. 6 there is illustrated a preferred configuration for the inventive vehicle restraint system 4.
- the system 4 comprises an airbag 6 having a looped pocket 42, an inflator can 44, an diffuser 46, including an ignition wire 48, and a housing 50.
- the inflator can 44 and diffuser 46 are disposed within both the airbag 6, particularly within the looped pocket 42, and within the housing 50.
- a restraint cover and/or door (neither illustrated) is generally placed over the undeployed airbag 6 when it is within the inflation module and stored either within the steering column or the dashboard of a vehicle.
- the airbag 6 comprises two body panel sections 30, 32 which are connected by a single substantially straight seam 34. Again, however, a single seam and single piece airbag is merely a preferred embodiment of the inventive system and airbag.
- the most important component of the invention is the pocket into which the inflator can assembly is disposed within both the folded and inflated airbag.
- the materials of construction from which the individual body panel sections 10, 12, end panels 14, 16, and rectilinear separator panel 18 are formed may be either similar or dissimilar from one another.
- Each of these panels may be formed from a number of materials including by way of example only and not limitation woven fabrics, knitted fabrics, non-woven fabrics, films and combinations thereof.
- Woven fabrics may be preferred with woven fabrics formed of tightly woven construction such as plain or panama weave constructions being particularly preferred.
- Such woven fabrics may be formed from yarns of polyester, polyamides such as nylon 6 and nylon- 6,6 or other suitable material as may be known to those in the skill in the art.
- Multifilament yarns having a relatively low denier per filament rating of not greater than about 1-4 denier per filament may be desirable for bags requiring particular good foldability.
- woven fabrics formed from synthetic yarns having linear densities of about 40 denier to about 1200 denier are believed to be useful in the formation of the airbag 2 according to the present invention.
- Fabrics formed from yarns having linear densities of about 315 to about 840 are believed to be particularly useful, and fabrics formed from yarns having linear densities in the range of about 400 to about 650 are believed to be most useful.
- each of the panels 10, 12, 14, 16, 18 may be formed of the same material, the panels may also be formed from differing materials and or constructions.
- one or both of the body panel sections 10, 12 and the end panels 14, 16 may be formed from an uncoated relatively high permeability fabric having an air permeability of about 5 CFM per square foot or higher while the separator panel 18 is formed from a coated or uncoated fabric having an air -Impermeability of about 3 CFM per square foot or less when measured at a differential pressure of 0.5 inches of water across the fabric.
- Fabrics having permeabilities of about 1-3 CFM per square foot may be desirable in either the body panels or center panel section.
- Fabrics having permeabilities below 2 CFM and preferably below 1 CFM in the uncoated state may be preferred. Such fabrics which have permeabilities below 2 CFM which permeability does not substantially increase by more than a factor of about 2 when the fabric is subjected to biaxial stresses in the range of up to about
- neoprene, silicone urethanes or disperse polyamides may be preferred.
- Coatings such as dispersed polyamides having dry add on weights of about 0.6 ounces per square yard or less and more preferably about 0.4 ounces per square yard or less and most preferably about 0.3 per square yard or less may be particularly preferred so as to minimize fabric weight and enhance foldability. It is, of course, to be understood that aside from the use of coatings, different characteristics in various panels may also be achieved through the use of fabrics incorporating differing weave densities and/or finishing treatments such as calendaring as may be known to those in the skill of the art.
- airbag 2 has been illustrated and is described herein in terms of the principal panel sections 10, 12, 18, it is to be understood that such airbag 2 may also include additional components such as shape defining tethers, gas vents, and the like as may be known to those in the skill of the art. While specific embodiments of the invention have been illustrated and described, it is to be understood that the invention is not limited thereto, since modifications may certainly be made and other embodiments of the principals of this invention will no doubt occur to those skilled in the art. Therefore, it is contemplated by the appended claims to cover any such modifications and other embodiments as incorporate the features of this invention which in the true spirit and scope of the claims hereto.
