Abstract

A system for monitoring the deployment of an airbag. The system includes a sensor adapted to generate a signal and a flexible member having an indicator portion. The indicator portion inhibits at least a portion of the signal from transmitting through the flexible member.

Claims

1. An airbag deployment monitoring system comprising:

an airbag module adapted to deploy an airbag;

a dispenser disposed proximate the airbag module;

a flexible member including;

a first end disposed proximate the dispenser,

a second end disposed opposite the first end and proximate the airbag, and

an indicator portion disposed at the second end and having a predetermined length, the indicator portion having first and second shading elements having first and second linear sides that extend at an angle from the second end; and

a sensor disposed near the flexible member, the sensor having a transmitter adapted to project a beam toward the flexible member and a receiver adapted to detect the beam;

wherein the indicator portion is shaded along the predetermined length to inhibit at least a portion of the beam from transmitting through the flexible member along the predetermined length.

2. The system of claim 1 wherein the indicator portion is shaded along the predetermined length such that the indicator portion is darker than a portion of the flexible member disposed adjacent to the indicator portion.

3. The system of claim 1 wherein the indicator portion includes a point of intersection disposed along the second end.

4. The deployment monitoring system of claim 1 wherein the indicator portion includes a first shaded section having first, second, and third sides.

5. The deployment monitoring system of claim 4 wherein at least one side is disposed parallel to the second end.

6. The deployment monitoring system of claim 5 further comprising a second shaded section having first, second, and third sides.

7. The deployment monitoring system of claim 6 wherein at least one side of the first shaded section is disposed adjacent to the second shaded section.

8. The deployment monitoring system of claim 1 wherein the indicator portion is shaded such that a first shaded area is contiguous with a second shaded area.

9. An airbag deployment monitoring system comprising:

an airbag module adapted to deploy an airbag;

a dispenser disposed proximate the airbag module;

a flexible member including;

a first end disposed proximate the dispenser,

a second end disposed opposite the first end and proximate the airbag, and

an indicator portion disposed near the second end, the indicator portion having a plurality of tinted sections including first and second shaded sections each having at least three sides and each having at least one side disposed at an angle relative to the second end; and

a sensor disposed near the flexible member, the sensor having a transmitter adapted to project a light beam toward the flexible member and a receiver adapted to detect the light beam;

wherein the plurality of tinted sections are configured to inhibit a portion of the light beam from transmitting through the flexible member.

10. The deployment monitoring system of claim 9 wherein the first and second shaded sections intersect.

11. The deployment monitoring system of claim 9 wherein the indicator portion has a predetermined length and the plurality of tinted sections are spaced apart from each other such that at least a portion of the light beam is reflected by at least one tinted section along the predetermined length.

12. The deployment monitoring system of claim 9 wherein at least one side of the first shaded section is disposed parallel to the second end.

13. The deployment monitoring system of claim 9 wherein at least one side of the second shaded section is disposed parallel to the second end.

14. The deployment monitoring system of claim 9 wherein at least one side of the first shaded section is disposed adjacent to the second shaded section.

15. The deployment monitoring system of claim 9 wherein the first shaded section is contiguous with a second shaded section.
