Abstract: A device for protecting a person standing in a motor vehicle comprises numerous airbags installed in a motor vehicle, a scanner for determining where there is empty space adjacent to the person, and a control unit that is configured to only deploy those airbags that inflate into the empty space that has been determined.

Abstract: A roof air bag apparatus for a vehicle includes a roof air bag cushion protecting a passenger, and the roof air bag cushion can be separated into a front air bag cushion and a rear air bag cushion. In particular, the front air bag cushion and the rear air bag cushion are unfolded into a space between a front passenger and a rear passenger in a face-to-face mode at the time of occurrence of a car accident, such that the unfolded front air bag cushion protects the front passenger by absorbing an impact force, and the unfolded rear air bag cushion protects the rear passenger by absorbing an impact force.

Abstract: A roof mounted airbag is proposed. The roof mounted airbag includes: a fixed chamber having an upper portion fixed to a roof of a vehicle and configured to be expanded downward when gas is supplied into the fixed chamber; a first separated chamber connected to the fixed chamber, having an inside that communicates with an inside of the fixed chamber to be supplied with the gas from the fixed chamber, and configured to be expanded downward when the gas is supplied into the first separated chamber; and a second separated chamber connected to the fixed chamber while being spaced apart from the first separated chamber, having an inside that communicates with the inside of the fixed chamber to be supplied with the gas from the fixed chamber, and configured to be expanded downward when the gas is supplied into second separated chamber.
