Abstract
A belt retractor has a locking pawl actuated by an electromagnet. The electromagnet is operated with a holding power that is reduced in comparison to its actuation power. The holding power may be provided by a series device in the current supply of the electromagnet. The series device may generate a holding voltage that is limited to a predefined value, or it may provide a pulse duration modulated d.c. supply voltage.
