    • Lightweight, thermoplastic, vehicle headliners each having at least one integrally-formed, energy-absorbing, head-impact mechanism and injection molding methods for making same are provided. Each headliner includes a stiff, self-supporting, thermoplastic sheet adapted to be mounted adjacent a roof of the vehicle so as to underlie the roof and shield the roof from view. The sheet has an upper surface and a lower surface. Each energy-absorbing, head-impact mechanism absorbs energy of an impact with its associated headliner by a passenger of the vehicle. In one embodiment, the at least one head-impact mechanism includes a plurality of spaced-apart, energy-absorbing, thermoplastic structures, such as ribs, which are connected to and extend upwardly from the upper surface of its thermoplastic sheet. In another embodiment, the at least one head-impact mechanism includes a fabric or other material having a foam backing bonded to the lower surface of the thermoplastic sheet to create a cosmetically-acceptable appearance for the headliner and which is compressed by a passenger of the vehicle to absorb energy of the impact. In yet another embodiment, the at least one head-impact mechanism includes a series of tubular voids formed in the thermoplastic sheet and which are compressible for absorbing energy of the impact. Each headliner also preferably includes at least one attachment mechanism such as a hollow, plastic grab handle integrally formed with its thermoplastic sheet.
    • 提供了各自具有至少一个整体形成的能量吸收头冲击机构和用于制造其的注射成型方法的轻质,热塑性,车顶头饰。 每个顶篷包括一个刚性的自支撑的热塑性片材,其适于安装在车辆的屋顶附近,以便在屋顶下方并且遮蔽屋顶。 片材具有上表面和下表面。 每个能量吸收头部冲击机构由车辆的乘客吸收与其相关联的顶篷的冲击能量。 在一个实施例中,所述至少一个头部冲击机构包括多个间隔开的能量吸收的热塑性结构,例如肋条,其连接到其热塑性片材的上表面并向上延伸。 在另一个实施例中,所述至少一个头部冲击机构包括具有泡沫背衬的织物或其它材料,所述泡沫背衬接合到所述热塑性片材的下表面,以产生所述顶篷的美容上可接受的外观,并且被所述乘客压缩 车辆吸收能量的影响。 在另一个实施例中,至少一个头部冲击机构包括形成在热塑性片材中并且可压缩以吸收冲击能量的一系列管状空隙。 每个顶篷还优选地包括至少一个附接机构,例如与其热塑性片材一体形成的中空塑料抓斗。
