Abstract
A system includes a seatbelt retractor having a spool and a braking claw selectively engageable with the spool. The system includes an actuator designed to inhibit engagement of the braking claw with the spool. The system includes a processor and a memory storing program instructions executable by the processor to actuate the actuator to inhibit engagement of the braking claw with the spool for a threshold amount of time after detecting an impact of a vehicle.
Claims15
A system comprising, a processor and a memory storing program instructions executable by the processor to:
- actuate an actuator to inhibit rotational restriction of a spool relative to a housing of a seatbelt retractor for a threshold amount of time after detecting an impact of a vehicle;
- and
- actuate the actuator to permit rotational restriction of the spool relative to the housing after the threshold amount of time has lapsed.
A method comprising:
- inhibiting rotational restriction of a spool relative to a housing of a seatbelt retractor for a threshold amount of time after detecting an impact of a vehicle;
- and
- permitting rotational restriction of the spool relative to the housing after the threshold amount of time has lapsed.
A system comprising, a processor and a memory storing program instructions executable by the processor to:
- actuate an actuator to inhibit rotational restriction of a spool relative to a housing of a seatbelt retractor for a threshold amount of time after detecting an impact of a vehicle;
- and
- actuate the actuator to permit rotational restriction of the spool relative to the housing after the threshold amount of time has lapsed;
- wherein the memory further stores instructions to actuate a seatbelt pretensioner before actuating the actuator to inhibit rotational restriction of the spool relative to the housing.
