AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively protect the safety of occupants in adjacent seats during a vehicle collision, especially to prevent contact between occupants in adjacent seats.

Method used

A side airbag device for vehicles is designed, comprising a main chamber and a secondary chamber. The main chamber expands and extends from above the center armrest to the side of the first seat, and the secondary chamber protrudes and expands from the main chamber toward the side of the second seat, clamping the center armrest to restrain the waist of the second seat occupant and change their head trajectory to avoid contact between them.

Benefits of technology

Through the coordinated action of the main chamber and the auxiliary chamber, the occupants of the first and second seats can be effectively restrained, preventing them from coming into contact with each other and improving the occupant protection effect.

Abstract

Provided is a vehicle side airbag device capable of efficiently protecting adjacent occupants from each other. A vehicle side airbag device (100) includes an inflator (116) fixed to a first seat (102) and an airbag cushion (114) that receives gas from the inflator (116) and expands and deploys. The airbag cushion (114) has a main chamber (120) that expands and deploys at least from a range above a center console (130) to a range on a side of the first seat (102) of the center console (130), and a sub chamber (122) that protrudes from a portion of the main chamber (120) located above the center console (130) toward a second seat (128) side and expands and deploys to a range on a side of the second seat (128) of the center console (130).
