Pedestrian protection airbag device

Abstract

The present disclosure provides a pedestrian protection airbag device including an airbag cushion that expands during a vehicle collision and deploys from a boundary part between a hood and a windshield of the vehicle to protect pedestrians and the like. The pedestrian protection airbag device includes: a temporary fastening part that temporarily fastens a part of the airbag cushion so as to divide a chamber that forms an internal space of the airbag cushion into a front expansion part that deploys on an upper part of a hood in the initial stage of expansion and deployment of the airbag cushion, and a rear expansion part that deploys near a lower end part of a windshield; and an inflator that discharges gas toward the front expansion part so as to deploy the front expansion part earlier than the rear expansion part.

Dependencies are inferred from the claim text.
