  • Vehicle sensitive seat belt retractor control with suppressed Z-axis sensitivity
    Patent number: 7568649
    Abstract: A vehicle sensitive retractor control system having reduced sensitivity to Z-axis acceleration experienced during normal driving. The retractor control system incorporates a rolling mass and a locking lever which, in a resting position, are arranged such that the locking lever does not engage a ratchet wheel of a seat belt retractor spool. In response to accelerations in the horizontal plane, the rolling ball mass becomes unseated from its resting position and engages the locking lever, causing it to pivot and lock the retractor. In response to Z-axis acceleration, the rolling mass is prevented from contacting the locking lever by a mass restrictor. A soft damping spring is also provided to bias the locking lever against a lever rest. The spring is sized to overcome the inertia of the locking lever and prevent it from “bouncing up” and engaging the ratchet wheel in response to Z-axis accelerations.

  • Inflator device having modular construction and radial inflation gas flow
    Patent number: 7568728
    Abstract: A modular inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device has an elongated cylindrical configuration and includes a supply of gas generant material to produce inflation gas upon reaction initiation. The inflator device includes a reaction housing defining a reaction chamber containing the supply of gas generant material. An initiator device is connected to the reaction housing and in reaction initiating communication with the supply of gas generant material. The reaction housing includes a plurality of radially oriented chamber discharge openings. Upon reaction initiation of the supply of gas generant material, the inflation gas discharges from the reaction chamber through the discharge openings. An initiator diffuser is disposed between the initiator device and the supply of gas generant material.

  • Locking mechanism for a cinch tube of an airbag cushion
    Patent number: 7568729
    Abstract: An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a tube that may be restricted to prevent gas venting. A cord having a plurality of stoppers is coupled to the tube. Upon airbag deployment, the cord extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the cord incrementally tightens the tube and restricts gas venting. If the cushion encounters an obstruction, the cord remains lax and the tube is able to vent gas.

  • Hybrid inflator with extended filling capability
    Patent number: 7533900
    Abstract: A “hybrid” inflator having an extended filling capacity is disclosed. This inflator is designed to deploy an inflatable curtain airbag. The inflator will have an inner chamber that is connected to an outer chamber by a bleed hole. The inner chamber has a first supply of gas and a pyrotechnic material. This first supply of gas is sufficient to inflate an inflatable curtain after ignition of the pyrotechnic material. The outer chamber has a second supply of gas. The second supply of gas bleeds out of the outer chamber through the inner chamber and into the inflatable curtain. The inflatable curtain may be initially filled by the first supply of gas in the inner chamber while the second supply of gas slowly bleeds out of the inflator into the curtain to maintain the curtain at a desired pressure sufficient to provide impact protection to the vehicle occupant.

  • Airbag inflation with sliding baffle
    Patent number: 7527291
    Abstract: A new type of airbag inflator is described. The airbag inflator includes a chamber that houses a quantity of inflation gas. The inflation gas is capable of filling and deploying an airbag. The inflator also includes a membrane that seals the chamber. A sliding baffle is also added to the inflator. The sliding baffle is positioned proximate the membrane. The sliding baffle has a membrane rupture mechanism and a plurality of gas flow holes. Upon initiation of the inflator, the sliding baffle slides to cause the rupture mechanism to fail the membrane. The rupture mechanism fails the membrane by detaching a single piece from the membrane. The single piece is sufficiently large such that it remains within the inflator (or within the sliding baffle) and does not pass through one of the gas flow holes.
