SEAT CUSHION AIRBAG APPARATUS

摘要

A seat cushion airbag apparatus is applied to a vehicle seat including a seat unit having a seat cushion supported, from a lower side thereof, by a supporting portion of a seat frame, and an air blowing duct having a blow-out port below the seat cushion, wherein a conditioning air flowing through the air blowing duct is blown out upward from the blow-out port. An inflator is disposed at a location, which is spaced from the blow-out port in a front and rear direction of a vehicle, and an airbag, is inflated between the supporting portion and the seat cushion by an inflation gas supplied from the inflator so that a seat face of the seat unit is raised to prevent a subject to be restrained on the seat unit from being moved forward.

1. A seat cushion airbag apparatus adapted to be applied to a vehicle seat including a seat unit having a seat cushion supported, from a lower side thereof, by a supporting portion of a seat frame, and an air blowing duct having a blow-out port below the seat cushion, wherein a conditioning air flowing through the air blowing duct is blown out upward from the blow-out port,
wherein an inflator is disposed at a location, which is spaced from the blow-out port in a front and rear direction of a vehicle, and an airbag is inflated between the supporting portion and the seat cushion by an inflation gas supplied from the inflator so that a seat face of the seat unit is raised to prevent a subject to be restrained on the seat unit from being moved forward, and wherein a section of the airbag, which is located more toward the blow-out port than the inflator, becomes a folded portion, wherein the folded portion before being inflated by the inflation gas is accordion-folded in a front and rear direction of the vehicle seat and is disposed at a location, which is located more toward the inflator than the blow-out port, and, the folded portion when being inflated by the inflation gas is deployed between the inflator and a location, which is located more remote from the inflator than the blow-out port.
