Embodiment Construction

[0041] Hereinafter, one embodiment of the present invention will be described based on the drawings. Such as figure 1 As shown, in the embodiment, the knee protection airbag device S disposed in front of the passenger seat is taken as an example for description.

[0042] The knee protection airbag device S according to the embodiment is arranged below the glove box 1 arranged in front of the passenger seat. In addition, the up-down, left-right, and front-rear directions in this specification correspond to the up-down, front-back, and left-right directions of a vehicle equipped with the knee protection airbag device S unless otherwise specified.

[0043] Such as figure 1 , figure 2 As shown, the knee protection airbag device S has the following components, namely: a folded airbag 28; an inflator 19 that supplies inflation gas to the airbag 28; a housing 7 that accommodates the folded airbag. The airbag 28 and the inflator 19 ; and the airbag cover 15 covering the opening 7...

Abstract

An airbag of a knee-protecting airbag device is mounted on a case together with an inflator with the aid of mounting means of the inflator. The airbag includes a vehicle body side panel, an occupant side panel, a mounting inflatable region which is located in a lower end region of the airbag as deployed and is secured to the case, and a knee-protecting region. The airbag further includes a tether which is joined to the occupant side panel in the mounting inflatable region of the airbag by the lower end inside the airbag for preventing a sagging movement of the vehicle body side panel in a region of the mounting inflatable region distant from the inflator in a left and right direction at airbag deployment.

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...
