VEHICLE OCCUPANT PROTECTION DEVICE

摘要

A vehicle occupant protection device includes a frontal collision airbag that is provided in front of a front seat, and inflates and deploys by gas being supplied into the airbag, and in which vent holes are provided in both a right side and a left side thereof; a frontal collision inflator that supplies the gas into the airbag by being activated; a discharge limiting portion capable of limiting a discharge of the gas from at least one vent hole, from among the left vent hole and the right vent hole; and a controller that activates the frontal collision inflator when a frontal collision is detected or predicted, and that controls the discharge limiting portion such that the discharge limiting portion limits the discharge of the gas from the one vent hole when a configuration of the frontal collision is an asymmetric collision on a side with the one vent hole.
