    • An energy-absorbing hood assembly for a vehicle includes an upper layer having a plurality of polyhedral protuberances extending outward therefrom, and preferably a lower layer. The protuberances are disposed between the upper and lower layers, and preferably arranged in longitudinal and transverse rows. The polyhedral protuberances are adapted to absorb and attenuate crush loads imparted to the hood assembly and resultant forces imparted to an object resulting from an impact between the object and the hood assembly. The polyhedral protuberances define various structural and material characteristics along different regions of the hood assembly that are selectively configured to provide different levels of absorption and attenuation of the crush loads and resultant forces. The lower layer is preferably configured to controllably fail at a first predetermined threshold crush load and the polyhedral protuberances are each configured to controllably deform at a second predetermined threshold crush load.
    • 用于车辆的能量吸收罩组件包括具有从其向外延伸的多个多面体突起的上层,优选为下层。 突起设置在上层和下层之间,并且优选地布置在纵向和横向行中。 多面体突起适于吸收和减弱施加到罩组件的挤压载荷以及由物体和罩组件之间的冲击所产生的对物体的合力。 多面体突起限定沿着罩组件的不同区域的各种结构和材料特性,其选择性地构造成提供不同程度的挤压载荷和合力的吸收和衰减。 优选地,下层被配置为在第一预定阈值压碎载荷下可控地失效,并且多面体突起各自构造成在第二预定阈值压碎载荷下可控地变形。

    • An energy-absorbing hood assembly for a vehicle includes an inner layer operatively secured to an upper layer having a first interface surface. The inner layer has opposing first and second surfaces defining a sinusoidal profile that is oriented to extend from the forward end of the vehicle towards the rearward end of the vehicle. The sinusoidal profile includes varying amplitudes and wavelengths along different regions of the hood assembly. The amplitudes and wavelengths are individually configured to provide regionally distinct predetermined levels of absorption and attenuation of kinetic energy imparted to the hood assembly by an object upon impact therebetween. Preferably, the hood assembly also includes a lower layer having a second interface surface; wherein the inner layer has a plurality of bonding surfaces attached to the first and second interface surfaces to thereby define a plurality of laterally oriented channels.
    • 用于车辆的能量吸收罩组件包括可操作地固定到具有第一界面表面的上层的内层。 内层具有相对的第一和第二表面,其限定正弦曲线,其被定向成从车辆的前端朝向车辆的后端延伸。 正弦曲线包括沿着罩组件的不同区域的变化的幅度和波长。 幅度和波长被单独地构造成提供区域上不同的预定水平的吸收和衰减由物体在其间碰撞时赋予罩组件的动能。 优选地,罩组件还包括具有第二界面表面的下层; 其中所述内层具有附接到所述第一和第二界面表面的多个粘合表面,从而限定多个横向定向的通道。
