Integrated side air curtain and inflator overhead system
First Claim
1. An integrated passive occupant restraint system comprising:
- a headliner mounted inside a vehicle and across the interior roof of the vehicle, the headliner including a plurality of separate layers with edges of said layers being overlaid along an outer periphery of the headliner, the headliner operative to insulate the vehicle from outside sound and outside temperature;
an inflatable restraint curtain compression molded to a compressed position within the plurality of layers, the inflatable restraint curtain operative to cushion a vehicle occupant'"'"'s head and torso during a side impact collision;
a plurality of sensors located at different points of the vehicle, the plurality of sensors operative to detect a collision and to generate a corresponding signal; and
a gas generator in fluid communication with the inflatable restraint curtain, the gas generator generating gas in response to the signal generated by the plurality of sensors, such that the generated gas inflates the curtain causing the curtain to separate said edges for deployment therebetween to cover the window of the vehicle.

Abstract
An integrated headliner and passive occupant restraint system and a method of manufacturing the integrated headliner and passive occupant restraint system and headliner is provided. The system includes a headliner, an inflatable restraint air curtain and a gas generator. The headliner is mounted inside a vehicle and across the interior roof of the vehicle. The headliner may include a plurality of layers comprised of PET Batt material or the like. The headliner insulates the vehicle from outside sound and outside temperature. The inflatable restraint curtain is disposed within the plurality of headliner layers, the inflatable restraint curtain operative to cushion a vehicle occupant'"'"'s head and torso during a side impact collision. Furthermore, a gas generator is in fluid communication with the inflatable restraint curtain. The gas generator generates gas in response to the signal generated by the plurality of sensors. The generated gas inflates the curtain causing the curtain to expand and tear the seam between the layers of the headliner and to cover the window of the vehicle.

9. A method of manufacturing an integrated vehicle headliner and air curtain assembly comprising:
-
providing a plurality of separately overlaid headliner layers arranged with terraced edges proximate a side portion of the interior of the vehicle;
positioning an inflatable air curtain between said plurality of layers; and
compression molding the plurality of layers to form a headliner assembly with the air curtain tightly compressed between said layers proximate the terraced edges to minimize packaging requirements. - View Dependent Claims (10)
