Abstract: A supplemental restraint sub-module configured for integral use with a vehicle steering wheel comprising an air bag and an inflator enclosed in a fabric envelope. The sub-module is designed to be incorporated into a well in the central hub section of a steering wheel and is configured to use the well walls and steering wheel mounting plate as reaction surfaces during air bag deployment. The sub-module design eliminates the need for a module housing and thus is smaller and lighter than traditional modules. A membrane horn switch and backing plate can also be incorporated into the sub-module design. The reduced number of parts needed to manufacture the sub-module of the present invention allows the sub-module to be manufactured at a cost reduction. The reduced size and weight of the sub-module allows room for turn signal, light controls, wiper controls and redundant accessory switches to be attached by allowing extra room for the electronics needed to operate these functions.

Abstract: An occupant restraint system composed of a compact air cushion module containing a rotating vent ring which creates a variable venting system for inflation of an air cushion. The rotating vent ring moves to open one or more vents of different flow areas which allows inflation gas to vent to the atmosphere thereby controlling the pressure with which the inflatable air cushion fills. The rotating vent ring has a neutral or non-rotated position wherein the venting is minimized such that the inflatable air cushion fills with a maximum pressure. The rotating vent ring is rotated to a variety of positions in response to one or more changing environmental conditions within the vehicle. Such conditions may include occupant position, seat belt usage, occupant weight, ambient temperature or any other relevant environmental factor.

Abstract: An inflatable restraint system having a head/thorax air bag cushion configured to protect the head and thorax regions of a motor vehicle occupant during a side impact collision. The air bag is configured to be kidney shaped when inflated to optimize the protection area while eliminating excess volume. The air bag is inflated from the bottom up, thus inflating the region adjacent the thorax area of the occupant first. As the thorax area is loaded by the occupant, gas is forced into the head area of the air bag. As the head area is loaded by the occupant, gas is vented to atmosphere through vents located in the head area of the air bag.

Abstract: An air bag module with adjustable cushion inflation is provided by including a valve member in the module which is movable to change the size of an inflation outlet through which inflation fluid flows into an air cushion while simultaneously changing the size of a vent outlet which enables inflation fluid to be vented to the ambient atmosphere. The valve member is positioned by a control unit which receives input from various sensors within the vehicle regarding such factors as ambient temperature, occupant position, occupant weight, seat belt usage, etc to produce an optimum cushion inflation based upon these factors.

Abstract: An easy-to-use seat belt mechanism is provided for use with a child seat and includes a seat belt retractor having a reel with a seat belt wound thereon which can be extended about a child in the child seat. A pawl and ratchet form a retractor mechanism for blocking rotation of the reel and seat belt protraction to restrain the child in the seat. A manually rotatable shaft is connected to the reel to wind the reel in a rewind direction to tighten the seat belt about the child and provide an accurate sensation of increasing belt tension on the child. A manually operable release is operable to disable the pawl and ratchet mechanism to allow protraction of the belt with rotation of the reel and thereby allowing removal of the child from the child seat. The release also allows the belting to be readily readjusted if the belt is not properly tightened about the child.

Abstract: A vehicle side impact restraint system especially adapted for providing head impact protection. The system employs a deployable restraint curtain which is maintained stowed in an undeployed condition within a slot along the upper edge of a vehicle side door window. A track assembly is vertically mounted along the rear edge of the window and includes a gas generator, a track, and a sliding projectile. The upper edge of the triangularly shaped curtain is attached to the vehicle whereas the rear end of the lower edge is mounted to the projectile. Upon deployment, the sliding projectile pulls the curtain to a downward position in response to a deployment signal sent to the gas generator. The projectile reaches the lower end of the track where it is locked in position thus stretching the curtain across a portion of the window area, thus providing a surface for impact energy absorption.
