Z-shaped folded webbing for safety belt of vehicle, has tear tapes exhibiting different seam thickness in edge areas such that portions are formed with tear seam with different seam thickness at edge regions

摘要

The webbing (1) has folding layers formed at edge areas (1.5, 1.6) and connected by tear tapes (2). The tear tapes exhibit different seam thickness in the edge areas such that portions (A1-A3) are formed with a tear seam (2.1) with different seam thickness at edge regions, where bandwidth of the webbing is divided into two exterior portions (1.2, 1.4) and a middle portion (1.3). A belt inner space (1.1) is filled with fluid by a gas generator or a hose when collision is detected by a collision sensor system of a vehicle. The gas generator or the hose is connected with the inner space.
