  • Patent number: 10526426
    Abstract: Disclosed are photoinitiators that are ultra violet (UV) reactive. The photoinitiators can be polymerized into polymeric backbones for use in UV curable hot melt pressure sensitive adhesives. The preferred polymeric backbones are acrylic-based polymers. The photoinitiators are very UVC sensitive and have excellent hot melt viscosity stability that is many fold higher than existing photoinitiators. The subject photoinitiators feature aryl ketones linked through an ether linkage to a variety of connector sequences that allow for polymerization of the photoinitiators.

  • Publication number: 20070096451
    Abstract: A gas generator usable in a vehicle occupant protection system. The gas generator includes an initiator holder and an initiator secured within the holder, the initiator including a housing enclosing an initiator charge. A bore seal is molded into the initiator holder, and a casing is attached to the bore seal along an exterior surface of the bore seal. A gas generant material is positioned within the casing so as to enable fluid communication between the gas generant and combustion products formed by combustion of the initiator charge, thereby enabling ignition of the gas generant. In one embodiment, an edge portion of the casing is pre-formed so as to snap-fit over a shoulder formed along the bore seal. In another embodiment, an edge portion of the casing is crimped onto outer surfaces of the bore seal. In yet another embodiment, the casing is welded to the bore seal.

  • Publication number: 20070085318
    Abstract: An in-line seat belt pretensioner is provided that includes a frame containing a first guide member and a second guide member for tensioning of seat belt webbing upon pretensioner activation. As the pretensioner is activated, the seat belt is tensioned by activation of an actuator operably coupled to the second guide. The second guide is then routed over a vertically stationary first guide that is slidably engaged within a slot within the frame, thereby contributing to reducing the load on the occupant. A low-friction material employed in the manufacture of the guide member(s), contributes to a smoother and less abrupt tensioning of the seat belt upon activation of the pretensioner.

  • Publication number: 20060217711
    Abstract: Disclosed is a bone fracture fixation system, such as for reducing and compressing fractures in the proximal femur. The fixation system includes a plurality of elongated bodies with a helical cancellous bone anchor on a distal end of each of the bodies. An axially moveable plate with a plurality of openings is carried by the proximal end of the elongated bodies. The elongated bodies are rotated into position across the fracture or separation between adjacent bones and into the adjacent bone or bone fragment, and the plate is distally advanced to apply secondary compression and lock the device into place. The device may also be used for soft tissue attachments.

  • Publication number: 20060163864
    Abstract: A gas generating system (24) is provided including a gas generant container (34) and an initiator (28). The initiator (28) is positioned exterior of the gas generant container (34) so as to enable fluid communication with the container (34) upon activation of the initiator (28). A gas generant composition (32) is positioned within the container (34). The gas generant container (34) may have sufficient rigidity to maintain a predetermined shape prior to positioning of the gas generant (32) therein, and is penetrable by combustion products resulting from activation of the initiator (28). A seatbelt device (150) and a vehicle occupant restraint system (180) incorporating a gas generating system as described herein are also disclosed.

  • Publication number: 20060097506
    Abstract: A gas generator (10) is provided, comprising an initiator (48) including an initiator charge, a gas generant insert (52) spaced apart from the initiator (48), and a fluid-impermeable blast director (42) interposed between the initiator (48) and the gas generant insert (52). The blast director (42) provides a barrier between the gas generant insert (52) and a blast resulting from ignition of the initiator charge when the initiator charge is ignited. The blast director (42), when used with particular gas generant configurations, reduces the effects of the initiator blast and reduces the amount of gas generant exposed to the blast, enabling the structural integrity of the gas generant (52) to be maintained.

  • Publication number: 20060033317
    Abstract: A push-on retainer (16, 116) is provided for securing together an initiator (14) and another element of a gas generating system. The retainer (16, 116) includes a first portion (16a, 116a) for engaging a surface of the other element of the system, and a second portion (16b, 116b) coupled to the first portion for engaging a surface of the initiator (14) to secure the initiator to the other element of the gas generating system. A vehicle occupant protection system (180) is also provided which includes a gas generating system utilizing a push-on retainer (16, 116) for securing the initiator (14) to the other element of the gas generating system.

  • Publication number: 20060022443
    Abstract: Flame suppressants or catalysts, independent of the gas generant composition, reduce the flame front and carbon monoxide produced by combustion of gas generating compositions employed within gas generating systems such as vehicle occupant restraint systems, for example. Heterogeneous distribution of the flash suppressant and the gas generant within the gas generant bed facilitates, upon gas generator activation, a reduction in flame front of any known gas generant without reformulating the gas generating composition.

  • Publication number: 20050235863
    Abstract: The present invention generally relates to auto-ignition/booster compositions for inflators of occupant restraint systems, for example. An auto-ignition/booster composition in accordance with the present invention includes an auto-ignition composition combined with silicone. When uncured silicone is added to a mixture of the dry granulated constituents of both the auto-ignition and booster components, an extrudable or thixotropic mixture is produced. The uncured mixture may then be applied to any desired surface within an associated gas generator within a vehicle occupant protection system, for example, thereby simplifying gas generator manufacture. A gas generating system incorporating the present composition is also contemplated.

  • Publication number: 20050200103
    Abstract: An inflator (10) for use in an inflatable vehicle occupant protection system. In one aspect of the invention, the inflator (10) includes a longitudinal enclosure (22) having a substantially uniform cross-sectional area along at least a portion of the enclosure, and a gas generant composition (24) positioned along the portion of the enclosure (22). The gas generant composition (24) is distributed substantially uniformly along the portion of the enclosure (22). A plurality of gas exit apertures (40) is formed along the portion of the enclosure (22) to enable fluid communication between the enclosure (22) and an exterior of the enclosure. The apertures (40) are spaced apart a distance proportional to a desired rate of propagation of a combustion reaction of gas generant positioned between the apertures (40).
