Abstract: A seat belt assembly for use in a seat belt system of a motor vehicle to restrain a vehicle occupant. The assembly includes a belt webbing extending from a first end to a second end and includes tubular webbing extending from the first end and configured to open at a tear seam. An airbag is disposed within the tubular webbing and configured to inflate and deploy through the tear seam. A gas generator is fluidly coupled to the airbag and configured to provide an expanding gas to inflate and deploy the airbag in response to a control signal. A first part of the airbag is configured to inflate above the tubular webbing such that the first part of the airbag is disposed between a side or door of the vehicle and the thorax of the vehicle occupant.

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.

Abstract: A vehicle sensitive retractor locking system which may have reduced sensitivity to Z-axis accelerations experienced during driving conditions. The locking system incorporates a ball mass which is maintained within a nest surface of a ball cage. A locking lever is provided having a pair of arms, including an upper and lower arm. The lower arm forms a support post which directly engages with the ball mass in the normal condition of the locking system. The upper arm forms an actuation rim which encircles the upper portion of the ball mass. When the ball mass is displaced within the nest surface in response to inertial forces, two locking modes are provided. First, by relieving pressure exerted by the ball against the post support as the ball is displaced, the locking lever is free to rotate into a locking condition. A secondary locking mode is provided through direct contact between the ball mass and the actuation rim of the locking lever upper arm.
