AIRBAG CUSHION AND AIRBAG APPARATUS FOR PASSENGER SEAT INCLUDING THE SAME

An airbag cushion and an airbag apparatus for a passenger seat including the same. A side panel portion of the airbag cushion is divided into a first panel portion, which is disposed at an upper position, and a second panel portion, which is disposed at a lower position, an open gap communicating with the outside is formed in an overlap region between the first panel portion and the second panel portion, and a low-risk deployment (LRD) vent for the airbag cushion is formed using the open gap. Accordingly, the configuration for forming the LRD vent is simplified.
