    • The present invention relates to a knee protection device for protecting the knees of an occupant when a vehicle collides. The protection device includes a knee protecting member which has a hollow cross-section outer frame composed of a front plate, a load-bearing plate, an upper plate and a lower plate, and a hollow cross-section inner frame integrally formed within the outer frame. The inner frame is integrally formed with the outer frame by connecting adjacent middle portions of the front plate, upper plate, load-bearing plate and lower plate, using plate-shaped ribs. Even if an action point on the load-bearing plate varies according to variation in height of the occupant's knee due to individual difference, impact energy is directly transmitted to the upper and lower plates as well as being dispersed and transmitted through the inner frame to the middle points of the upper, lower and front plates, efficiently received by the four plates constituting the outer frame, and thus the outer frame plastically deforms in a steady manner.
    • 膝盖保护装置技术领域本发明涉及一种用于在车辆碰撞时保护乘员膝盖的膝盖保护装置。 该保护装置包括一个具有由前板,承载板,上板和下板构成的中空横截面外框的膝盖保护构件,以及一体地形成在外侧的中空横截面内框架 帧。 通过使用板状肋连接前板,上板,承载板和下板的相邻中间部分,内框架与外框架一体形成。 即使承载板上的作用点由于个体差异而根据乘员膝盖的高度变化而变化,冲击能量直接传递到上板和下板,并且通过内框架分散和传递到 上,下板和前板的中点由构成外框的四个板有效地接收,从而外框稳定地塑性变形。
