Curtain air bag system

摘要

A curtain air bag system includes a curtain air bag that is housed folded up in an upper edge portion of a door opening, and that includes a first deployment portion that deploys when a vehicle is collided with in a side collision as well as when the vehicle rolls over, and a second deployment portion that deploys at least when the vehicle rolls over, by receiving a supply of gas. The first deployment portion deploys in a cylindrical shape extending in a vehicle longitudinal direction, above a belt line such that a rear end side of the first deployment portion overlaps with a center pillar when viewed from a side of the vehicle, and the second deployment portion deploys such that a lower end extends below the belt line, in a position not overlapping with the first deployment portion when viewed from the side.

主权项

1. A curtain air bag system comprising a curtain air bag that is housed folded up in an upper edge portion of an opening for getting into and out of a vehicle in a side of a vehicle body, and that includes a first deployment portion, a gas flow path, and a second deployment portion,
wherein the first deployment portion inflates by receiving a supply of gas when the vehicle is collided with in a side collision as well as when the vehicle rolls over, and deploys in a cylindrical shape having a longitudinal axis extending in a vehicle longitudinal direction, such that an entirety of the first deployment portion deploys above a belt line such that a rear most end of the first deployment portion overlaps with a center pillar when viewed from the side of the vehicle body, the gas flow path supplies gas to the first deployment portion from a gas passage located adjacent the first deployment portion, the gas passage is spaced apart from the center pillar when viewed from the side of the vehicle body, and the second deployment portion, in response to receiving a supply of gas, deploys such that a lower end extends below the belt line, in a position not overlapping with the first deployment portion when viewed from the side, at least when the vehicle rolls over.
