摘要：
A method and system (10) for controlling the tensioning of a vehicle seat belt utilizes a control processor (20) and a motor (12) to provide initial tensioning of the seat belt. After initial tensioning, the control processor (20) removes substantially all tension on the seat belt while continuously monitoring seat belt pay out via an encoder (18). The system provides out-of-position warnings, and is responsive to vehicle acceleration information from a crash discrimination system (22) and/or an object detecting radar system (26) to control tensioning of the seat belt. The system further provides for earlier seat belt tensioning activation by utilizing a pyrotechnic pretensioner (32) having a replaceable pyrotechnic cartridge (38).
