Side airbag arrangement has tensioning belt tensioning device in form of rewinding device for tensioning belt with motor-driven shaft for rewinding belt with associated blocking device to prevent unwinding and controller

摘要

The arrangement has an airbag extending over at least part of the length of the vehicle that is arranged in a folded state on the roof frame before triggering and unfolds downward when triggered and a tensioning belt attached to the lower end of the airbag and leading to an activatable tensioning device. The tensioning device is a rewinding device for the tensioning belt with a motor-driven shaft (25) for rewinding the belt with an associated blocking device to prevent unwinding and a controller (40,42).
