In particular, since a collision accident at a high speed travel is not only high in mortality but also has a high possibility of serious injury, An airbag is installed to protect passengers aboard the passenger seat more safely. In the case of a luxury automobile, an airbag capable of protecting the occupant of the driver's seat and the passenger seat as well as the passenger in the rear seat may be installed.

The airbag is equipped with an ultra-precision collision sensor capable of detecting a collision accident and a sudden stop during a high-speed running. In response to a signal of a collision sensor in case of an accident, gas is instantly sprayed to rapidly inflate the collapsed airbag to protect the passenger A front airbag, a knee airbag, a side airbag, and the like, which are mounted on the seat to protect passengers from the side glass portion.

In recent years, a high-output-type airbag is applied to improve the performance of the airbag, thereby increasing the size of the airbag and increasing the deployment speed.

However, in order to improve the livability of the passenger in the rear seat, the seatback is formed in a slim shape, so that the side and rear pads constituting the seatback are configured to be relatively thin.

Accordingly, when the airbag is deployed, the pad is broken from the thinnest portion of the pad by the developing pressure, and the broken pieces of the pad and the cover paper are scattered to injure the passenger's body.

In other words, when the pad is thinned, the stiffness is lowered, so that the airbag is not developed in the initial designed development direction, and the pad is broken and the passenger is wounded and the airbag is not developed in the designed direction. There is a problem that can not be protected.
