Seat belt retractor has second deformable energy-absorbing element which after predetermined rotational angle of belt spool relative to locking wheel is connected into force flux path between belt spool and locking wheel

摘要

The seat belt retractor has a belt spool (10) and locking wheel (16) which starting from an initial position are rotatable relative to one another, and has a first energy-absorbing element (14) installed between the belt spool and locking wheel. A second deformable energy-absorbing element (20) in the form of a pretensioned spring element after a predetermined rotational angle of the belt spool relative to the locking wheel is connected into the force flux path between the belt spool and locking wheel.
