Triggering arrangement for at least one safety device - contains pyrotechnical charge acted upon by mechanical acceleration sensor e.g. for belt tightener in motor vehicle

摘要

An arrangement for triggering at least one safety device contains a device which can be acted upon by a pyrotechnical charge connected to the safety device and a sensor for igniting the charge when an acceleration occurs which exceeds a defined limit. The mechanical sensor (51) contains an acceleration element (53) and an energy storage element (54) which triggers the ignition of the charge (3) when the acceleration indicates the presence of an acceleration above the limit value. ADVANTAGE - Low space requirement and ensures sufficient mechanical force is exerted.
