Abstract

In order to provide an airbag (10) that is constructed such that a gas-discharging amount from a venthole (18) becomes largest when an occupant (P) comes in contact with a center portion, in the left and right direction, of an occupant-facing surface of the expanded airbag (10), and an airbag apparatus provided with the airbag, a hanging strap (80) that couples a center portion of a front panel (12) and a rear panel (14) is provided in the airbag (10). A lid body (60) that covers the open-and-close type venthole (18) from outside the airbag (10), and the hanging strap (80) is coupled by means of a tether (70). In a case that the airbag (10) is expanded, the hanging strap (80) and the tether (70) are tensed, and the lid body (60) is brought to a state to close the open-and-close type venthole (18). A loosening amount of the hanging strap (80) and the tether (70) becomes largest when the occupant (P) comes in contact with the center portion of the front panel (12) of the expanded airbag (10) and causes the center portion to retreat, and an opening amount of the open-and-close type venthole (18) also becomes largest.

Description

technical field [0001] The present invention relates to an airbag comprising a vent hole for absorbing shock by flowing gas from the inside of the airbag to the outside of the airbag, and a restricting member that restricts the outflow of gas from the vent hole, and particularly relates to a structure configured until an object comes into contact with an occupant's facing surface of an inflated airbag An airbag that closes a vent hole and opens the vent hole when an object comes into contact with the occupant-facing surface of the inflated airbag that causes the occupant-facing surface to recede. Furthermore, the present invention relates to an airbag device including the airbag. [0002] However, in the following description, up, down, left, and right correspond to up, down, left, and right for a person facing the occupant-facing surface of the inflated airbag. [0003] In addition, in the present invention, an "object" refers to a human body seated on a seat, a child seat p...
