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 in a along a longitudinal extent of one of a cushion or a sock covering the cushion of a side cushion airbag assembly, each marking including at least one indicium defined by a plurality of polygonal shaped pixels;
a detector configured to capture digital images of the at least one indicium of the plurality of markings; and
a controller configured to process the digital images captured by the detector and determine presence of the at least one indicium of the plurality of markings to access an installed condition of the cushion or sock 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.

13. A side curtain airbag assembly comprising:
-
an inflatable cushion; and a sock for housing the cushion in a folded state, wherein at least one of the cushion and sock includes a plurality of spaced markings arrayed along its respective longitudinal extent, each marking is defined by at least two indicia including a first indicium and a second indicium, each of the first indicium and second indicium is formed from a plurality of similarly shaped and sized interconnected pixels which together provide for first and second indicia having a predetermined height and width. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of accessing an installed condition of a side curtain airbag assembly comprising:
-
providing a plurality of spaced markings along a length of a cushion or sock of the side curtain airbag assembly; defining each marking by at least two indicia including a first indicium and a second indicium having a shape differing from a shape of the first indicium, each of the first indicium and second indicium being formed from a plurality of similarly shaped and sized interconnected pixels; capturing images with a detector of the first and second indicia of the plurality of markings; and comparing the captured images of the first and second indicia of the plurality of marking with master images of the first and second indicia of the plurality of markings with a controller in communication with the detector to determine presence of each of the plurality of markings. - View Dependent Claims (20)
