Abstract: A knee airbag device includes an airbag module and an airbag door. The airbag module, which is provided inside a column cover that covers the rear end portion of a steering column, includes gas generation device that generates gas when a collision occurs, and a knee airbag that is inflated and deployed from a folded state when the knee airbag receives the gas from the gas generation device. The airbag door, which is provided in the lower portion of the column cover, is opened when the inflation pressure of the knee airbag is equal to or higher than a predetermined value. When the knee airbag is deployed, at least a portion of the airbag door is positioned between an interfering object that is positioned in an area on the side of the column cover, and at leaser a portion of the knee airbag.

Abstract: An arrangement and construction of a crew protective device for an automobile are capable of preventing pillar garnish from scattering when an air bag received in a front pillar portion expands. Received in a front pillar portion (20) is an air bag (16) in a space formed by a front pillar body (38) and a pillar garnish (40). When the air bag (16) expands, the pillar garnish (40) is pushed by an expansion pressure of the air bag (16) to form an opening between the front pillar body (38) and the pillar garnish (40), which opening permits expansion of the air bag (16), and through which the air bag (16) expands into a room. The air bag (16) is formed with a non-expansion portion, and the pillar garnish (40) is formed with a hinge portion (46), whereby an expansion pressure acting on the pillar garnish (40) upon expansion of the air bag (16) is small and the pillar garnish (40) is easily opened through the hinge portion (46).

Abstract translation: 当前端部分收纳的气囊膨胀时，用于汽车的机组保护装置的布置和结构能够防止支柱装饰散开。 在前柱部（20）中收纳有由前柱体（38）和柱装饰（40）形成的空间中的气囊（16）。 当安全气囊（16）膨胀时，支柱装饰件（40）被气囊（16）的膨胀压力推动，以形成前柱体（38）和支柱装饰件（40）之间的开口，该开口 允许气囊（16）的膨胀，并且气囊（16）通过该膨胀进入房间。 气囊（16）形成有非膨胀部分，并且柱装饰件（40）形成有铰链部分（46），由此在气囊膨胀时作用在支柱装饰件（40）上的膨胀压力 （16）很小，并且支柱装饰件（40）通过铰链部分（46）容易地打开。
