Inflatable restraint deployment ramp
First Claim
1. An inflatable restraint assembly, comprising:
- a vehicle pillar;
a pillar trim component that is attached to the vehicle pillar, the pillar trim component having an upper end;
a curtain airbag module having an inflatable curtain portion that is disposed in a stowed configuration prior to deployment and moves to a deployed configuration subsequent to deployment;
a guide ramp that is disposed between the inflatable curtain portion of the curtain airbag module and the upper end of the pillar trim component; and
a headliner having an outboard portion that is sandwiched between the guide ramp and the upper end of the pillar trim component prior to deployment of the inflatable curtain portion of the curtain airbag module, wherein a body portion of the headliner is connected to the outboard portion of the headliner by a frangible portion, such that the outboard portion of the headliner separates from the body portion of the headliner at the frangible portion during deployment of the inflatable curtain portion of the curtain airbag module.

4. An inflatable restraint assembly, comprising:
-
a vehicle pillar; a pillar trim component that is attached to the vehicle pillar, the pillar trim component having an upper end; a curtain airbag module that is located adjacent to the upper end of the pillar trim component, the curtain airbag module having an inflatable curtain portion that is disposed in a stowed configuration prior to deployment and moves to a deployed configuration subsequent to deployment; a guide ramp that is positioned adjacent to the vehicle pillar and is disposed between the inflatable curtain portion of the curtain airbag module and the upper end of the pillar trim component; and a headliner that conceals the inflatable curtain portion of the curtain airbag module when the inflatable curtain portion is in the stowed configuration and is separated from the upper end of the pillar trim component when the inflatable curtain portion of the curtain airbag module is in the deployed configuration, wherein the headliner includes an outboard portion that is disposed between and in engagement with the guide ramp and the upper end of the pillar trim component such that the guide ramp and the upper end of the pillar trim component cooperate to restrain movement of the outboard portion of the headliner prior to deployment of the inflatable curtain portion of the curtain airbag module, wherein a body portion of the headliner is connected to the outboard portion of the headliner by a frangible portion, such that the outboard portion of the headliner separates from the body portion of the headliner at the frangible portion during deployment of the inflatable curtain portion of the curtain airbag module. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. An inflatable restraint assembly, comprising:
-
a vehicle pillar having an upper portion and a lower portion; a pillar trim component that is attached to the vehicle pillar and conceals the lower portion of the vehicle pillar, the pillar trim component having an upper end with an upper surface; a curtain airbag module that is located adjacent to the upper end of the pillar trim component, the curtain airbag module having an inflatable curtain portion that is disposed in a stowed configuration prior to deployment and moves to a deployed configuration subsequent to deployment; a guide ramp that is disposed between the inflatable curtain portion of the curtain airbag module and the upper end of the pillar trim component, the guide ramp having an outboard end that is connected to the vehicle pillar, an inboard end, and a lower surface extending from the outboard end to the inboard end with a cavity defined between the lower surface of the guide ramp and the upper surface of the upper end of the pillar trim component, wherein at least a portion of the inflatable curtain portion of the curtain airbag module extends along the guide ramp when the inflatable curtain portion is in the deployed configuration; and a headliner that conceals the inflatable curtain portion of the curtain airbag module when the inflatable curtain portion is in the stowed configuration and is separated from the upper end of the pillar trim component when the inflatable curtain portion of the curtain airbag module is in the deployed configuration, wherein the headliner includes an outboard portion that is disposed within the cavity with a distal end of the outboard portion positioned outboard of the inboard end of the guide ramp, the outboard portion being in engagement with the inboard end of the guide ramp and the upper end of the vehicle pillar prior to deployment of the inflatable curtain portion of the curtain airbag module, and a body portion of the headliner is connected to the outboard portion of the headliner by a frangible portion, such that the outboard portion of the headliner separates from the body portion of the headliner at the frangible portion during deployment of the inflatable curtain portion of the curtain airbag module. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
