Problems solved by technology

[0010] In order to prevent such a phenomenon, it is also considered to use a high-output inflator to accelerate the inflation of the airbag, but the use of a high-output inflator leads to an increase in the size and cost of the airbag device.

Embodiment Construction

[0024] The airbag according to the first embodiment has a vent hole and a restricting unit that restricts the flow of gas from the vent hole, wherein the vent hole is provided on the side opposite to the passenger of the airbag in the inflated state or on the side opposite to the passenger of the airbag. On the side, the restricting unit includes a cover member covering the vent hole and a connecting member connecting the cover member to the occupant-opposite side through the interior of the airbag, wherein the occupant of the airbag is on the side closer to the center of the airbag than the vent hole. The opposite surface and the side opposite to the occupant are connected in a releasable manner by a coupling unit, and the midway portion in the extending direction of the connecting member is sandwiched between the portion facing the occupant and the side opposite to the occupant and is coupled by the coupling unit. When the internal pressure of the airbag changes When it is mo...

Abstract

An airbag and an airbag device, in which a vent hole is closed or has a small opening until the internal pressure of the airbag is above a predetermined level, and the vent hole is opened or has a large opening when the internal pressure of the airbag is above the predetermined level and, simultaneously, an occupant is in contact with the airbag. A vent hole (18) is provided in the rear panel (14) of the airbag (10) and covered with a lid member (60) from the inside of the airbag (10). A suspension belt (80), which connects, in the airbag (10), a front panel (12) and a rear panel (14) together, and the lid member (60) are connected by a tether (70). At a portion closer to the center of the airbag (10) than the vent hole, the tether (70) is held between the front panel (12) and the rear panel (14) and they are releasably joined together by linear bonding portions (22, 24).

Description

[0001] technology area [0002] The present invention relates to an airbag device including: a vent hole for softly blocking an occupant with an airbag by allowing gas to flow out from the inside of the airbag to the outside of the airbag; and a restricting unit that restricts the flow of gas from the vent hole. In addition, the present invention relates to an airbag device including the airbag. Background technique [0003] As is well known, an airbag is provided with a vent hole, and when a vehicle occupant falls into the inflated airbag, gas flows out from the inside of the airbag through the vent hole, and the airbag softly blocks the vehicle occupant and the like. [0004] Japanese Patent Laying-Open No. 6-127330 discloses an airbag of the following configuration: before the occupant-facing surface of the inflated airbag comes into contact with the occupant, the vent hole is always closed, and when the occupant contacts the occupant-facing surface of the inflated airbag, ...
