Abstract
Official abstract text for this publication.
A seat cushion airbag apparatus is applied to a vehicle seat in which a seat cushion includes a cushion part and a support portion. An airbag, including an inflatable portion, is disposed between the support portion and the cushion part. The inflatable portion includes: a rear inflatable portion that inflates on a lower side of buttocks of an occupant; a front inflatable portion that inflates on a lower side of a femur of the occupant; and a connection portion that connects the rear inflatable portion and the front inflatable portion. A tilting plate is disposed between the support portion and the cushion part and is supported to be tiltable in an upper-lower direction by a shaft provided rearward of the front inflatable portion, the tilting plate including a flat pressure receiving portion that receives pressure of inflation gas from a lower side through at least the front inflatable portion.
