Vehicle curtain airbag
First Claim
1. A post-deployment position-stabilized curtain airbag for installation in a vehicle to protect an occupant in case of side impact or rollover, the airbag comprising:
- (a) an inflatable passenger safety cushion supportable at a top edge thereof interior of the vehicle for deployment into the passenger compartment of the vehicle between the occupant and the occupant enclosure, the safety cushion has a rear portion with a cushion chamber deploying toward the rear of the passenger compartment and a forward portion remote therefrom;
(b) a fill chamber secured to the top edge of the safety cushion in fluid communication therewith, the fill chamber directing pressurized gas from an inflator into the safety cushion to effect deployment thereof; and
(c) an inflatable structural member mechanically connected to the safety cushion, the structural member being disposable upon installation in the vehicle for deployment into the passenger compartment between the deployed safety cushion and the occupant enclosure using pressurized gas directed from the fill chamber through the cushion chamber and enters the structural member through an auxiliary passageway communicating with the cushion chamber of the safety cushion, the deployed structural member serving to limit outboard displacement of the deployed safety cushion.

Abstract
A post-deployment, position-stabilized curtain airbag has a top edge from which an inflatable safety cushion is supported by a vehicle for deployment into a vehicle passenger compartment between occupant and occupant enclosure. A fill chamber is secured to the top edge of the safety cushion. An inflatable structural member is mechanically connected to the safety cushion. The fill chamber directs pressurized gas into the safety cushion and the structural member. The structural member deploys into the passenger compartment between the safety cushion and occupant enclosure limiting outboard displacement of the safety cushion. The structural member fully deploys after the safety cushion. Another structural member deploys along the top edge of the safety cushion limiting pivoting of the safety cushion there relative to the fill chamber. Pressurized gas enters each structural member through auxiliary passageways having oppositely directed entrances and outlets.

-
(a) an inflatable passenger safety cushion supportable at a top edge thereof interior of the vehicle for deployment into the passenger compartment of the vehicle between the occupant and the occupant enclosure, the safety cushion having a rear portion with a rearmost cushion chamber deploying toward the rear of the passenger compartment and a forward portion remote therefrom; (b) a fill chamber secured to the top edge of the safety cushion in fluid communication therewith, the fill chamber directing pressurized gas from an inflator into the safety cushion to effect deployment thereof; (c) an inflatable structural member mechanically connected to the rear portion of the safety cushion, the structural member being disposable upon installation in the vehicle for deployment into the passenger compartment between the deployed safety cushion and the occupant enclosure using pressurized gas directed from the fill chamber through the safety cushion, the deployed structural member serving to limit outboard displacement of the rear portion of the deployed safety cushion, and (d) an auxiliary passageway communicating between the rearmost cushion chamber of the safety cushion and the structural member, and pressurized gas from the safety cushion enters the structural member from the rearmost cushion chamber through the auxiliary passageway. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
