Problems solved by technology

However, when the side air belt device or the air curtain device is installed outside the air belt device, not only the cost is greatly increased, but also it is difficult to secure a space for installing the side air belt device or the air curtain device in a small vehicle.

Abstract

The invention discloses a vehicle occupant protection device. The protection device is a vehicle occupant protection device in which a seat belt expands to restrain the occupant, and can effectively restrain the occupant's chest, head and neck. Since the upper part of the inflatable part 43 of the safety belt 30 of the air belt device 25 is in a position and shape that can protect the side of the occupant's head H and neck N, the inflatable part 43 can not only restrain the occupant softly in the event of a frontal collision. The chest B can also softly restrain the occupant's head H and neck N with the inflatable part 43 when a side collision occurs, so that the air belt device 25 can have both the functions of a side air bag device and an air curtain device. Furthermore, since the thickness of the inflatable part 43 when inflated becomes thinner from the upper part toward the lower part, the required capacity of the inflator 28 can be reduced by reducing the volume of the lower part of the inflatable part 43 which is thin but easily obtains the necessary binding force.

Description

technical field [0001] The present invention relates to an occupant protection device that inflates a webbing that binds an occupant to a vehicle seat by high-pressure gas supplied from an inflator at the time of a vehicle collision. Background technique [0002] An air belt device for an automobile that accommodates an air bag inside a webbing of a seat belt and inflates the air bag to softly restrain an occupant during a collision is known from Japanese Patent Application Laid-Open No. 11-348720. In this air belt device, the thickness of the shoulder belt restraining the occupant when inflated is set to be thick at the middle portion in contact with the front of the occupant's chest, and thin at the upper and lower ends in contact with the neck and rib abdomen, thereby The volume when the airbag is inflated is suppressed to the minimum, and the required capacity of the inflator is reduced. [0003] However, the above-mentioned existing air belt device is mainly aimed at r...
