    • An airbag (14) has a knee cushion portion (18) and a neck portion (22). The airbag (14) and inflator (50) are stored in a module housing (94) until deployment. The neck portion (22) extends to the knee cushion portion (18) and is sized so that upon inflation of the neck portion the knee cushion is advanced horizontally far enough away from the housing to cover a face of the instrument panel (16) as the knee cushion portion (18) inflates. The knee cushion portion (18) of the inflation chamber contains a tether (54) that guides the knee cushion portion in an upward direction. The tether (54) zigzags between a front panel (30) and a back panel (34) of the knee cushion (18). This design assists in the upward deployment of the knee cushion from the neck of the airbag. The knee cushion (18) has a passageway (46) spaced between a sidewall (38, 42) of the knee cushion portion (18) and the tether (54). This passageway (42) also serves to direct the knee cushion (18) upward. In this way, the inventive airbag module creates a quickly deploying surface that covers a portion of the vehicle instrument panel that could otherwise lead to injuries of the vehicle occupant's lower extremities.
    • 安全气囊(14)具有膝部缓冲部分(18)和颈部部分(22)。 安全气囊(14)和充气机(50)被储存在模块壳体(94)中直到展开。 颈部(22)延伸到膝部缓冲部分(18)并且其尺寸设定成使得在颈部部分膨胀时,膝垫缓冲器水平地远离壳体前进远足以将仪表板(16)的表面覆盖为 膝部缓冲部分(18)膨胀。 充气室的膝部缓冲部分(18)包含一个在向上方向上引导膝垫部分的系绳(54)。 绳索(54)在膝盖垫(18)的前面板(30)和后面板(34)之间曲折。 该设计有助于从气囊的颈部向上部署膝垫。 膝垫(18)具有在膝垫部分(18)的侧壁(38,42)和系绳(54)之间分隔的通道(46)。 该通道(42)还用于将膝垫(18)向上引导。 以这种方式,本发明的安全气囊模块创建了一个快速展开的表面,该表面覆盖了车辆仪表板的一部分,否则可能导致车辆乘员的下肢受伤。
