AUTOMATED VISION INSPECTION OF A SIDE CURTAIN AIRBAG ASSEMBLY
First Claim
1. An automated vision inspection system for detecting whether a cushion of a side curtain airbag assembly system is in a properly installed or twisted state, the system comprising:
- a plurality of markings arrayed along a longitudinal extent of one of a cushion or a sleeve covering the cushion of a side cushion airbag assembly, each marking being defined by a pair of stacked indicia, each indicium of the pair of stacked indicia defined by a plurality of polygonal shaped pixels;
a detector configured to capture digital images of the plurality of markings; and
a controller configured to process the digital images captured by the detector and to determine presence of the indicia of the plurality of markings to assess an installed condition of the cushion or sleeve by comparison of the digital images to master images.

Abstract
An automated vision inspection system detects whether a cushion of a side curtain airbag assembly system is twisted. The cushion is provided a plurality of markings arrayed along a longitudinal extent of the cushion. Each marking can be defined by a group of four distinct characters or indicia. Each indicium can be defined by polygonal shaped pixels which allow the inspection system to find clear edges of the marking and thereby determine marking orientation. By determining orientation, the inspection system can compare the inspected marking to a master image of the marking to determine if the cushion is in a twisted state or non-twisted state.

16. A vehicle part for installation on a vehicle body comprising:
a part body including a plurality of spaced markings arrayed along a longitudinal extent of the part body, each marking is defined by a first upper row of indicia and a second lower row of indicia, each indicium of the first row of indicia is uniquely shaped compared to a shape of the other indicia provided in the first row of indicia, the first row and second row of indicia being formed from a plurality of similarly shaped and sized interconnected pixels, the plurality of markings allowing for determination of an installed state of the vehicle part. - View Dependent Claims (17, 18)

19. A method of accessing an installed condition of a vehicle part on a vehicle body comprising:
-
providing a vehicle part having a plurality of spaced marking along a length the vehicle part; defining each marking by a first upper row of indicia and a second lower row of indicia, each indicium of the first row of indicia and the second row of indicia being formed from a plurality of similarly shaped and sized interconnected pixels; capturing images with a detector of the plurality of markings; and comparing the captured images of the plurality of marking with master images with a controller in communication with the detector to determine presence of the plurality of markings along the length of the vehicle part. - View Dependent Claims (20)

21. A part for installation on an associated body comprising:
a part body including a plurality of spaced markings arrayed along a longitudinal extent of the part body, each marking is defined by at least two indicia including a first indicium and a second indicium, the first indicium being uniquely shaped compared to a shape of the second indicium, each of the first indicium and second indicium is formed from a plurality of similarly shaped and sized interconnected polygonal shaped pixels, the plurality of markings allowing for determination of an installed state of the part. - View Dependent Claims (22, 23, 24)
