Abstract

The present invention provides a side airbag device capable of further suppressing the amount of movement of an occupant and improving protection performance. The side airbag device (100) is providedwith an airbag cushion (106) and an inflator (108). The airbag cushion (106) is provided with: a connection section (120) that connects a prescribed range in the center of an occupant-side inner panel(106a) and a prescribed range in the center of an opposite-side outer panel (106b) to each other; and a tether (114) that spans the connection section (120) in the inner panel (106a) and the place below the connection section (120). The inflator (108) is connected below the connection portion (120) in the airbag cushion (106). The connection portion (120) of the airbag cushion (106) includes: a U-shaped region (122) having a U-shape with an upper opening; and a protruding region (132) protruding from the U-shaped region (122) toward a leading edge (134) of the airbag cushion (106). The airbagcushion (106) is inflated in a curved state toward the occupant side starting from the protruding region (132) due to the tension of the tether (114).

Description

technical field [0001] The present invention relates to a side airbag device for laterally restraining a vehicle occupant. Background technique [0002] In recent years, almost all vehicles are equipped with airbag devices as standard. The airbag device is a safety device that works in emergency situations such as a vehicle collision. The airbag cushion is inflated and deployed under air pressure to support the occupant for protection. [0003] There are various types of airbag devices depending on the installation location and usage. For example, in order to protect occupants from collisions from the front and rear directions, a front airbag device is provided in the center of the steering device. In addition, in order to protect occupants from impacts such as side collisions from the vehicle width direction, curtain airbag devices are installed near the ceiling above the side windows, and side airbag devices are installed on the side of the seats. [0004] Today's airba...
