Abstract

The present application obtains, at a low price, a roof airbag system capable of protecting an occupant regardless of the position of a vehicle seat and the posture of the occupant, and a vehicle. A lifting mechanism for lifting the thighs of an occupant is provided at the cushion side of the vehicle seat, and when a collision of the vehicle is detected by a collision sensor for detecting a collision of the vehicle, the thighs of the occupant are lifted by a seat control unit, and an inflator is operated by a gas control unit to generate gas. Therefore, the roof safety air bag is expanded and expanded. In this manner, the space between the thighs of the occupant and the upper body is reduced by raising the thighs of the occupant via the seat cushion, thereby reducing the volume at which the roof airbag is deployed, and reducing the amount of deployment of the roof airbag. This makes it possible to reduce costs by suppressing the amount of deployment of the roof airbag.

Description

technical field [0001] The present disclosure relates to a roof airbag system and a vehicle. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 2016-030546 discloses a technique related to an airbag device for a rear seat that can be inflated from a roof in a vehicle compartment. In this prior art, the airbag device is provided with: a first airbag part deployed from the roof of the vehicle toward the lower side in the vertical direction of the vehicle and the front side of the rear seat; The upper part and the front surface of the first airbag part in the deployed state abut against the inflation and deployment of the airbag. In addition, when the rear seat occupant absorbs the impact, the first airbag portion abuts against the second airbag portion, thereby suppressing the swinging of the first airbag portion toward the vehicle front side. [0003] In addition, JP-A-2020-063004 discloses a technique related to an occupant protection devi...
