Vorrichtung zum Aufwickeln eines Sicherheitsgurtes

摘要

The arrangement has a spring whose first end engages a belt spool and whose second end engages a point outside the spool and an actuator motor with which at least one end can be adjusted. The second end position and the spool rotary motion can be detected and a signal can be formed from corresponding signals, depending on which at least one end can be adjusted so the spring force of the spring corresponds to a defined spring force characteristic. The arrangement has a belt spool (10), a spring (16) whose first end (11) engages the spool and whose second end (12) engages a point outside the spool and an actuator motor (17) with which at least one end can be adjusted. The position of the second end and the rotary motion of the spool can be detected and a signal can be formed from corresponding signals, depending on which at least one end can be adjusted so the spring force of the spring corresponds to a defined spring force characteristic. AN Independent claim is also included for the following: (a) a method of regulating a spring force of a spring in a safety belt arrangement.
