Title: VEHICLE DRIVER SEAT AIRBAG DEVICE
Abstract:
A vehicle driver seat airbag device comprises a main airbag, a sub airbag, and a restriction device. The main airbag is mounted on a steering wheel of a vehicle so as to be inflated, due to a vehicle collision, between the steering wheel and a driver sitting in a driver seat of the vehicle. The sub airbag is additionally inflated toward the driver from the rear of the main airbag. The restriction device selectively inflates the sub airbag according to a vehicle collision mode or a driver condition. Therefore, the sub airbag is selectively inflated according to the body size of the driver or the vehicle collision mode such that an effect of protecting the driver, specifically reducing brain damage to the driver, is increased.
