Abstract
A first and a second spring are connected in series to a take-up shaft of a seatbelt so as to generate wind-up force; when the seatbelt is put on by an occupant, a pawl is engaged with a latch gear provided at a connecting portion between said springs, whereby the biasing force of only one of said springs is imparted to the take-up shaft, thereby decreasing the wind-up force of the take-up shaft; after the seatbelt is released from the occupant, the pawl is disengaged from the latch gear by a camplate means, whereby the wind-up forces of both springs are imparted to the take-up shaft, thereby increasing the wind-up force of the take-up shaft; and further, frictional means for engaging the latch gear with the pawl is brought into frictional contact with the take-up shaft by means of a pair of projecting resilient means oscillatingly movable, thereby securing the engagement between the latch gear and the pawl.
