Abstract
To provide a seatbelt retractor in which wiring of lead wires in a cover is not required. Instead, a circuit board and the like can be positioned accurately, and the circuit board is sufficiently protected during the mounting of mechanical components. A circuit board is anchored to a groove of an inner cover mounted on a retainer so that the inner cover covers the circuit board at the periphery of the inner cover with rotation axles and pivot mating with mating holes, respectively, at ends thereof.
Claims11
A seatbelt retractor comprising:
- a spool for spooling a webbing;
- a motor for driving the spool to rotate in a direction to spool the webbing;
- a power transmission structure for transmitting the rotational driving force of the motor to the spool;
- a circuit board provided with a circuit for controlling the rotation of the motor and connectors for feeding current;
- a rotational direction determining unit for determining the rotational direction of the spool;
- and
- a retainer for mounting the motor, the power transmission structure, the circuit board, and the rotational direction determining unit on a surface thereof;
- and,
- an outer cover mounted on the retainer to cover the surface of the retainer including the power transmission structure, the circuit board, and the rotational direction determining unit;
- and
- wherein the rotational direction determining unit comprises a limit switch mounted on the circuit board via a resilient member.
