Abstract

A component position detector for determining if a first component is properly attached to a second component. The component position detector can be a steering wheel airbag position detector that provides for a convenient and cost-effective apparatus and/or process for determining whether or not a steering wheel airbag is properly attached to a steering wheel. Such a steering wheel airbag position detector can include a jig that has a scan position, the scan position located on a front side of a steering wheel. In addition, the position detector can include a sensor rigidly attached to the jig, the sensor operable to perform a two-dimensional scan across a gap between the steering wheel and a steering wheel airbag and/or horn pad attached to the steering wheel.

Claims

1. A steering wheel airbag position detector comprising:

a jig located on a front side of a steering wheel, said jig having;

a first bar with a first flange dimensioned to extend over a circumferential portion of the steering wheel;

a second bar extending at an angle relative to said first bar, said second bar having a pair of spaced apart flanges with each flange dimensioned to rest on a planar support of the steering wheel;

a sensor rigidly attached to said jig, said sensor operable to detect and measure a gap between the steering wheel and a steering wheel airbag attached to the steering wheel;

a processor in communication with said sensor, said processor operable to analyze the measurement of the gap and provide a pass signal and a no-pass signal as a function of the analyzed measurement of the gap.

2. The steering wheel airbag position detector of claim 1, wherein said sensor is selected from a group consisting of a laser, a camera and an ultrasonic transducer.

3. The steering wheel airbag position detector of claim 2, wherein said sensor is a laser operable to perform a two dimensional (2D) laser scan across said gap between the steering wheel and the steering wheel airbag attached to the steering wheel and said processor analyzes said 2D laser scan and provides a pass signal and a no-pass signal as a function of the analyzed 2D laser scan.

4. The steering wheel airbag position detector of claim 3, wherein said processor determines a lateral distance between the steering wheel and the steering wheel airbag from the 2D laser scan.

5. The steering wheel airbag position detector of claim 3, wherein said processor determines an elevation distance between the steering wheel and the steering wheel airbag from the 2D laser scan.

6. The steering wheel airbag position detector of claim 1, wherein said pass signal indicates that the gap is within a tolerance defined by a user and said no-pass signal indicates that the gap is not within the tolerance defined by the user.

7. The steering wheel airbag position detector of claim 3, further comprising a memory operable to store data selected from the group consisting of data in the form of a plurality of 2D laser scans, data in the form of a plurality of pass signals, data in the form of a plurality of no-pass signals and combinations thereof.

14. The steering wheel airbag position detector of claim 1, wherein said first flange is an L-shaped flange.

15. The steering wheel airbag position detector of claim 1, wherein said first flange is a U-shaped flange.

8. A process for determining whether or not a steering wheel airbag has been properly attached to a steering wheel, the process comprising:

providing a steering wheel, a steering wheel airbag and a horn pad on the steering wheel airbag;

attaching the steering wheel airbag to a front side of the steering wheel, the steering wheel airbag and the front side of the steering wheel having a gap therebetween;

providing a steering wheel airbag position detector having;

a jig located on a front side of a steering wheel;

a laser rigidly attached to the jig, the laser operable to perform a two-dimensional (2D) laser scan and positioned to scan across a gap between the steering wheel and the horn pad on the steering wheel airbag;

a processor in communication with the laser, the processor operable to analyze the 2D laser scan of the gap, determine a lateral distance or an elevation distance between the horn pad and the steering wheel from the 2D laser scan and provide a pass signal and a no-pass signal as a function of the analyzed 2D laser scan;

analyzing the 2D laser scan using the processor and determining if the gap between the steering wheel and the horn pad is within a tolerance defined by a user, for the purpose of determining whether or not the steering wheel airbag has been properly attached to the steering wheel.

9. The process of claim 8, wherein the processor determines the lateral distance between the horn pad and the steering wheel from the 2D laser scan.

10. The process of claim 8, wherein the processor determines the elevation distance between the horn pad and the steering wheel from the 2D laser scan.

11. The process of claim 8, wherein the processor provides a pass signal if the gap between the steering wheel and the horn pad is within the tolerance defined by the user and a no-pass signal if the gap between the steering wheel and the horn pad is not within the tolerance defined by the user.

12. The process of claim 11, further including an assembly line and a motor vehicle with the steering wheel and steering wheel airbag being assembled on the assembly line, wherein the processor stops the assembly line if a no-pass signal is provided.

13. The process of claim 8, further including a data storage device, the data storage device storing data selected from the group consisting of data in the form of a plurality of 2D laser scans, data in the form of a plurality of pass signals, data in the form of a plurality of no-pass signals and combinations thereof.
