Abstract
Abstract An automatic locking and releasing arrangement for vehicular seat belt including a guide rail provided with first and second guide passages, a driving cable adapted to slide through the first guide passage, a connector and a cam both fixed to the cable at a predetermined spacing from each other, a slider adapted to slide through the second guide passage and engage the connector and the cam, a seat belt attached to the slider through a buckle, and an anchor device for retaining the slider in a locking seat belt position. A ring-like slide member is fixed to the cable portion positioned between the connector and the cam, the ring-like slide member comprising plurality of slide portions having a sectional shape a little smaller than that of the first guide passage and arranged through a flexible portion formed between adjacent slide portions. The cable is slid through the first guide passage of the guide rail by the slide portions of the ring-like slide member.
