Abstract

An airbag system has a curtain airbag, a first airbag and an airbag guiding member. The curtain airbag is installed along an A-pillar or a roof structure within a passenger compartment and deploys covering at least a window section of a door and a portion of the A-pillar. The first airbag is installed to a forward structure within the passenger compartment and deploys to an inflated orientation covering at least a portion of the forward structure. The airbag guiding member is installed to a side area of the forward structure adjacent to the door, a forward area of the door adjacent to the A-pillar or the A-pillar. The airbag guiding member moves to a position in which the airbag guiding member urges the curtain airbag and the first airbag into contact with one another as the curtain airbag and the first airbag move to their respective inflated orientations.

First claim

What is claimed is:

1. A vehicle airbag system, comprising:
a vehicle body structure that defines a passenger compartment and includes an A-pillar, a roof structure, a forward structure of the passenger compartment and a door that moves between an open orientation exposing the passenger compartment and a closed orientation that conceals at least a portion of the passenger compartment;
a curtain airbag installed to the vehicle body structure within the passenger compartment along at least one of the A-pillar and the roof structure, the curtain airbag being configured to move from a stowed orientation concealed along the at least one of the A-pillar and the roof structure, to an inflated orientation covering at least a window section of the door and a portion of the A-pillar;
a first airbag installed to the forward structure within the passenger compartment, the first airbag being configured to move from a stowed orientation concealed within the forward structure, to an inflated orientation covering at least a portion of the forward structure; and
a trim panel installed to one of a side area of the forward structure adjacent to the door, a forward area of the door adjacent to the A-pillar and the A-pillar, the trim panel being configured to move from a stowed orientation along one of the side area of the forward structure, the forward area of the door and the A-pillar, to a deployed orientation in which the trim panel is positioned to guide the curtain airbag and the first airbag into contact with one another as the curtain airbag and the first airbag move to their respective inflated orientations upon deployment.

2. The vehicle airbag system according to claim 1 , wherein
the forward structure is defined by one of the following:
an instrument panel that extends along a forward area of the passenger compartment, and
a steering column assembly that extends rearward from the forward area of the passenger compartment and/or the instrument panel, the steering column assembly having a steering wheel assembly supported at a rearward end thereof.

3. The vehicle airbag system according to claim 2 , wherein
the trim panel is installed to a side area of the instrument panel adjacent to the door and configured such that in the stowed orientation the trim panel is flush with adjacent surfaces of the instrument panel and in the deployed orientation the trim panel is moved rearward away from the adjacent surfaces of the instrument panel.

4. The vehicle airbag system according to claim 2 , wherein
the trim panel is installed to the door adjacent to the A-pillar and configured such that in the stowed orientation the trim panel is flush with adjacent surfaces of the door and in the deployed orientation the trim panel is moved inboard and upward away from the adjacent surfaces of the door.

5. The vehicle airbag system according to claim 2 , wherein
the trim panel is installed to the A-pillar between the door and the instrument panel and configured such that in the stowed orientation the trim panel is flush with adjacent surfaces of the A-pillar and in the deployed orientation the trim panel is moved rearward away from the adjacent surfaces of the A-pillar.

6. A vehicle airbag system, comprising:
a vehicle body structure that defines a passenger compartment and includes an A-pillar, a roof structure, a forward structure of the passenger compartment and a door that moves between an open orientation exposing the passenger compartment and a closed orientation that conceals at least a portion of the passenger compartment;
a curtain airbag installed to the vehicle body structure within the passenger compartment along at least one of the A-pillar and the roof structure, the curtain airbag being configured to move from a stowed orientation concealed within the one of the A-pillar and the roof structure, to an inflated orientation covering at least a window section of the door and a portion of the A-pillar;
a first airbag installed to the forward structure within the passenger compartment, the first airbag being configured to move from a stowed orientation concealed within the forward structure, to an inflated orientation covering at least a portion of the forward structure; and
a supplemental airbag installed to one of a side area of the forward structure adjacent to the door, a forward area of the door adjacent to the A-pillar and the A-pillar, the supplemental airbag being configured to move from a stowed orientation concealed within one of the side area of the forward structure, the forward area of the door and the A-pillar, to an inflated orientation in which the supplemental airbag is positioned to guide the curtain airbag and the first airbag into contact with one another as the curtain airbag and the first airbag move to their respective inflated orientations, the supplemental airbag being spaced apart from and separate from the curtain airbag, and, spaced apart from and separate from the first airbag in the stowed orientation.

7. The vehicle airbag system according to claim 6 , wherein
the forward structure is defined by one of the following:
an instrument panel that extends along the forward area of the passenger compartment, and
a steering column assembly that extends rearward from the forward area of the passenger compartment and/or the instrument panel, the steering column having a steering wheel assembly supported at a rearward end thereof.

8. The vehicle airbag system according to claim 7 , wherein
the supplemental airbag is installed to a side area of the instrument panel adjacent to the A-pillar and is inflated upon deployment.

9. The vehicle airbag system according to claim 7 , wherein
the supplemental airbag is installed to a lower section of the A-pillar adjacent to a side area of the instrument panel and is inflated upon deployment.

10. The vehicle airbag system according to claim 7 , wherein
the supplemental airbag is installed to an upper forward section of the door adjacent to the A-pillar and a side area of the instrument panel and is concealed by a trim panel that is movable upon deployment of the supplemental airbag.

11. The vehicle airbag system according to claim 6 , wherein
the supplemental airbag is configured and dimensioned to inflate upon deployment filling a space along the A-pillar adjacent to a side area of the forward structure thereby preventing the curtain airbag and the first airbag from inflating into the space along the A-pillar.
