Disclosed is a seatbelt webbing including an auxetic portion. The seatbelt webbing includes an auxetic portion elongated along an axis. The auxetic portion includes a plurality of segments rotatably connected to each other at hinges. The hinges are spaced along the axis and are transverse to the axis. The auxetic portion includes a plurality of strands. Each strand is embedded in at least two of the hinges. When tensile force above a predetermined level is applied to the auxetic portion by a vehicle occupant, e.g., the chest of the vehicle occupant, the auxetic portion both stretches along the axis and widens transverse to the axis, i.e., has a negative Poisson ratio.
本公开提供了“包括拉胀部分的安全带织带”。一种安全带织带,包括沿轴线伸长的拉胀部分。所述拉胀部分包括多个区段,所述多个区段在铰接件处可旋转地彼此连接。所述铰接件沿所述轴线间隔开,并且横向于所述轴线。所述拉胀部分包括多根线绳。每根线绳嵌入至少两个所述铰接件中。当高于预定水平的拉力由车辆乘员(例如车辆乘员的胸部)施加到所述拉胀部分时,所述拉胀部分既沿所述轴线拉伸又横向于所述轴线变宽,即具有负泊松比。
