Abstract

An arrangement for selectively disconnecting an airbag fitted within a passenger compartment of a motor vehicle. The arrangement includes a visible warning means retractable within a component and adapted to be withdrawn to extend over at least a predetermined region of the component. The warning means cooperates with airbag deployment means such that when the warning means is in its retracted position, the airbag deployment means is armed and when the warning means is in its withdrawn position, the airbag deployment means is disarmed.

Claims

1. An arrangement for selectively disconnecting an airbag fitted within a passenger compartment of a motor vehicle, said airbag being provided with an airbag deployment device, said arrangement comprising a visible warning member retractable within a component inside the passenger compartment and adapted to be withdrawn to extend over at least a predetermined region of said component, said warning member cooperating with said airbag deployment device

such that when said warning member is in a retracted position within said component, said airbag deployment device is armed and when said warning member is in a withdrawn position, said airbag deployment device is disarmed.

2. The arrangement as claimed in claim 1, wherein said visible warning member is a ribbon.

3. The arrangement as claimed in claim 1, wherein said warning member cooperates with a switch to electrically disarm said airbag deployment device when said warning member is in said withdrawn position.

4. The arrangement as claimed in claim 1, wherein said warning member cooperates with a shutter to mechanically disarm said airbag deployment device when said warning member is in said withdrawn position.

5. The arrangement as claimed in claim 4, wherein said shutter is arranged to pass between a squib and a gas generator precharge of the airbag deployment device.

6. The arrangement as claimed in claim 4, wherein said shutter is arranged to block an inflation valve for said airbag.

7. The arrangement as claimed in claim 1, wherein said visible warning member is a strip.

8. The arrangement as claimed in claim 1, wherein said visible warning member is of a highly visible color.
