ABSTRACT:
A retractor for restraining webbings wherein two webbings, i.e., a lap restraining webbing and a shoulder restraining webbing are wound round a single take-up shaft one over the other, and tension detecting means is provided for detecting the tension of the remaining wound-up portion of at least one of said two restraining webbings. Said tension detecting means has such a construction that when the tension of said one of the restraining webbings is lower than a predetermined value, it prevents the wind-off rotation of said take-up shaft, whereby said one of the restraining webbings, which is wound off as accompanied with the wind-out of the other restraining webbing, is prevented from being slackened and blocking up the interior of retractor.
