Abstract
A latch device for a runner member used in a passive seat belt system includes a longitudinally extending guide member, a runner member movably mounted on the guide member and having an engaging portion and webbing attached thereto, a driving member for moving the runner member between a passenger restraining position and a passenger releasing position, and a latch member movably mounted on a base member between an engaging position in which the latch member is engageable with the engaging portion of the runner member and a non-engaging position. The latch member is biased toward the engaging position. A cam member is fixed to the driving member, and a slide member, which connects the runner member with the driving member, is slidable relative to the driving member within a predetermined range. The cam member moves the latch member into the non-engaging position when the runner member is about to leave the passenger restraining position together with the driving member.
