Abstract

The airbag is mounted on the housing together with the inflator using the mounting unit of the inflator. The airbag includes a vehicle body side wall portion and a passenger side wall portion, and includes an attachment-side inflatable portion and a knee protector. The attachment-side inflatable portion is disposed on the lower end side when inflation is completed and is attached to the housing. The tether connects the lower end side of the airbag to the passenger side wall portion at the site where the side inflation portion is attached, and the tether is used to connect the vehicle in the area separated from the inflator in the left-right direction at the attachment side inflation portion when the inflation is completed. The downward displacement movement of the body side wall portion is restricted.

Description

technical field [0001] The present invention relates to a knee-protecting airbag device configured by accommodating a folded airbag and an inflator for supplying inflation gas to the airbag in a substantially box-shaped casing. A protrusion opening for allowing the airbag to protrude is arranged on the lower end side of the housing. Background technique [0002] At present, as an airbag device for knee protection, as shown in Japanese Patent Application Laid-Open No. 2013-119327, there is a structure in which an airbag accommodated in a housing having an opening for protruding is disposed on the lower end side and is inflated by The machine is installed on the mounting screws of the casing, and the inflator is installed on the casing together. [0003] In this conventional airbag device for knee protection, the airbag uses an inflator to attach the portion of the installation-side inflatable portion attached to the casing to the casing, and the casing has a structure in whi...
