  • Publication number: 20240300432
    Abstract: An airbag chute-integrated crash pad assembly includes: a main core that includes a door portion expanding when an airbag expands, and a cover portion mounted on a dash board. In particular, the main core is formed with a reinforcement portion extending downward from a lower surface of the cover portion, and the door portion and the cover portion are separated by a hinge groove that is formed in a lower surface of the main core and forms an expansion line. The reinforcement portion is combined with an airbag accommodation body that accommodates a passenger airbag (PAB). Thus, process optimization can be realized by omitting a process of machining a score and fusing a PAB chute, and also a problem of damage to the PAB chute can be solved.
