摘要： A plurality of tubes are connected in a bundle that is bent to follow a curved tortuous path. The method includes providing a plurality of individual tubes and then encapsulating the tubes within a molded or extruded encapsulating material so that the tubes are joined and supported together in a tube assembly. Connectors are provided on the ends of the tubes, either before or after the encapsulating of the tubes. The tube assembly is then bent to the desired bent tortuous shape.

摘要： An air duct for a vehicle includes a housing and a ductile member. The housing is formed from a first extrudable material having a first elastic modulus, and a second extrudable material having a second elastic modulus that is different from the first. The housing has a central longitudinal axis, defines a cavity therethrough along the axis, and is transitionable from a preform configuration in which the axis is substantially straight, to an installation configuration in which the axis is tortuous. The ductile member is embedded within the housing and is formed from a third extrudable material having a third elastic modulus that is greater than each of the first and second. The ductile member is bendable to transition the housing from the preform configuration to the installation configuration and is configured for retaining the housing in the installation configuration. A vehicle includes the air duct.
摘要翻译： 用于车辆的风道包括壳体和延性构件。 壳体由具有第一弹性模量的第一可挤压材料和具有与第一弹性模量不同的第二弹性模量的第二可挤压材料形成。 壳体具有中心纵向轴线，沿着轴线限定穿过其中的空腔，并且可从轴线基本上直线的预制件构型转变为轴线曲折的安装构型。 所述延性构件嵌入在所述壳体内并且由第三可挤压材料形成，所述第三可挤压材料具有大于所述第一和第二弹性模量的第三弹性模量。 延性构件是可弯曲的，以将壳体从预成型件构型转变到安装构造，并且被构造成将壳体保持在安装构型中。 车辆包括风道。
