  • Patent number: 6704674
    Abstract: A control system for a seatbelt retractor for a seatbelt retractor is to perform the operating performance test of the retractor mounted on a holder structure with at least one sensor and a locking device cooperating therewith throughout a wider range of tilt angle using a PLC, in which the control system includes a motor control portion connected to the PLC to control the rotation of motors at a tilt angle to be inputted in advance; a rotary cylinder control portion for controlling the rotating of a rotary cylinder in order to rotate a spool of the retractor; a stamping control portion for controlling the operating timing of a stamping portion; a memory for enabling various control operations of the PLC; a data register for storing digital data code values corresponding to a plurality of tilt angles; and a multi-axle motion controller for computing the digital data values, therefore enabling the tilt angle of the retractor to be tested with the holder structure being slanted.
