Abstract: A nitrogen injection assembly for use in coloring and curing optical fibers is disclosed. The nitrogen injection assembly includes a cover section and a distribution seal. An optical fiber coated with ink passes from a coating die to a curing chamber via a passageway defined by the cover section and the distribution seal. The distribution seal injects nitrogen into the passageway to keep the coated fiber and the curing chamber substantially free of oxygen. With the distribution seal positioned closer to the curing chamber than the cover section, the apparatus minimizes the risk of leaks in the passageway and the number of required seals.

Abstract: A tamper-resistant cover for an air bag and an apparatus and method for controlling the deployment of an air bag is disclosed. The tamper-resistant cover includes one or more regions in a surface of the tamper-resistant cover that is/are less tear-resistant than the material which is used throughout the remaining portions of the cover. This tearable portion or portions readily rips upon deployment of the air bag when pressurized gas rapidly fills the underlying air bag thereby allowing rapid deployment of the air bag as desired. Selective locations for the tearable region or regions on the cover desirably may be used to assist in altering the way in which the air bag deploys during a crash or other impact. The tearable regions on the bag cover may be formed in a variety of different ways. For example, the tearable regions maybe formed by providing mechanical wear to the desired region on the cover.

Abstract: The present invention relates to a buckle assembly for use in a restraint system for protecting a vehicle passenger during a crash event. The buckle assembly includes a connector, an airbag buckle and a means for ensuring that the connector may only be inserted into an airbag buckle and that the connector may only be inserted into an airbag buckle in a single orientation. The connector includes a mechanical stop with an offset edge. This offset edge must engage within a clearing slot located within the airbag buckle in order for the connector to latch into the airbag buckle. Latching of the connecting element with other non-airbag buckles or with the air bag buckle when the connector is not in the proper orientation is thus prevented.

Abstract: The disclosed invention relates to self-centering airbags, restraint systems that use them and the methods for manufacturing and tuning them. Sculpturing, which includes forming at least one cutout in the airbag, is used to form an airbag that when deployed, has a centerline that is not necessarily centered about the point at which the airbag is fixed to a structure (the fixation point). The self-centering airbag can be used as part of a restraint system, wherein the self-centering airbag is embedded within a structure such as a safety belt. Because the centerline of the self-centering airbag can be adjusted, the self-centering airbag does not need to be embedded in the safety belt in a location that, when worn by a passenger, is central with respect to the relevant part of the passenger's body.
