Abstract

A switch ( 60 ) is provided for disabling an airbag assembly ( 20 ) in an automotive vehicle when a sun visor ( 30 ) in the vehicle is positioned within a defined deployment area of the airbag assembly. The sun visor is movable in and out of the deployment area during regular use. A switch is adapted for signaling the presence or absence of the sun visor in the deployment area, and accordingly disables or enables the airbag assembly, respectively.

Claims (15)

1. An airbag disable system for an automotive vehicle having a roof, windshield, and windows, said airbag disable system comprising:

an airbag assembly for inflating and discharging an inflatable airbag into a deployment area in response to an impact upon the vehicle;

a visor assembly pivotally attached to the vehicle and movable between a plurality of positions in and out of said deployment area; and

a switch operatively coupled between said airbag assembly and said visor assembly for disabling said airbag assembly when said visor assembly is positioned within said deployment area.

2. An airbag disable system as set forth in claim 1 , wherein said visor assembly includes a bracket fixedly secured to the roof, and a substantially L-shaped arm having a generally horizontal cantilevered portion terminating at a distal end and a generally vertical portion, said bracket adapted to rotatably receive said vertical portion, thereby attaching said arm to the vehicle and allowing said cantilevered portion to swing through a plurality of positions.

3. An airbag disable system as set forth in claim 2 , wherein said visor assembly further includes a visor flap rotatably supported by said cantilevered portion of said arm for allowing rotation of said visor flap between a generally horizontal position aligned with the roof of the vehicle and a generally vertical position suited for shielding eyes of the occupant from light entering through one of the windshield and windows.

4. An airbag disable system as set forth in claim 3 , wherein said visor assembly further includes a support fixedly secured to the vehicle for supporting said distal end of said arm, said support including fingers adapted for surrounding and holding said distal end thereby allowing said arm to be releasably held in a stored generally horizontal position aligned with the roof.

5. An airbag disable system as set forth in claim 4 , wherein said switch is mounted on said support for cooperating with said distal end of said arm and sending a signal to control deployment of said airbag assembly.

6. An airbag disable system as set forth in claim 5 , wherein said switch includes a push button projecting between said fingers of said support such that when said distal end engages said push button said switch sends a signal to prevent deployment of said airbag assembly.

7. An airbag disable system as set forth in claim 5 , wherein said distal end of said arm includes a magnetic core embedded within and said switch includes a magnetic sensor for sensing the proximity of said distal end to control deployment of said airbag assembly.

8. An airbag disable system as set forth in claim 5 , wherein said switch includes a sensor for sensing the angular position of said vertical portion of said arm relative to said bracket to determine the proximity of said distal end of said arm from said support and therefrom controlling deployment of said airbag assembly.

9. An airbag disable system as set forth in claim 1 , further including a controller operatively coupled between said airbag assembly and said switch for receiving signals and operatively controlling the deployment of said airbag assembly therefrom.

10. An airbag disable system as set forth in claim 9 , further including a collision sensor operatively connected to said controller for sending a signal to said controller upon a vehicle collision.

11. An airbag disable system as set forth in claim 10 , wherein said controller receives signals from said collision sensor and said switch to control deployment of said airbag assembly.

12. An airbag disable system as set forth in claim 11 , further including an inflating device operatively coupled between said controller and said airbag assembly for receiving a signal from said controller and triggering the inflation of said airbag assembly.
