Abstract
A vehicle safety restraint arrangement includes a retractable and extractable belt, a belt reel on which the belt is windable, a retraction mechanism adapted to retract the belt from an extracted position, and a belt retraction brake adapted to limit the retraction speed of the belt during retraction of the belt by imparting a braking force to the belt reel during retraction of the belt via inductance. The present disclosure also relates to a method for limiting the retraction speed of a belt arranged on a belt reel.
Claims15
A vehicle safety restraint arrangement comprising:
- a retractable and extractable belt;
- a belt reel on which the belt is windable;
- a retraction mechanism adapted to retract the belt from an extracted position;
- and
- a belt retraction brake adapted to limit the retraction speed of the belt by imparting a braking force to the belt reel during retraction of the belt, the braking force of the belt retraction brake being impartable to the belt reel via inductance.
A method for limiting retraction speed of a belt arranged on a belt reel, the belt reel being adapted for a vehicle safety restraint arrangement, the method comprising:
- retracting the belt onto the belt reel using a retraction mechanism;
- and
- limiting maximum speed during the retraction by imparting a braking force to the belt reel using induction.
