Claims

[Scope of utility model registration request]

(1) A take-up shaft for winding the occupant restraint webbing, an elastic body that urges the take-up shaft in the webbing winding direction, a connecting shaft to which the rotation of the take-up shaft is transmitted, and the connecting shaft Wrapping around the connecting shaft includes a wire whose length changes as the connecting shaft rotates, and a webbing draw-out amount detection means that detects the change in length and detects the webbing pull-out amount. and a holding mechanism that receives the output from the webbing pull-out amount detection means and suppresses the biasing force of the elastic body while an occupant is driving.

(2) The holding mechanism stores the webbing maximum unwinding position within a predetermined time after the webbing is pulled out when the occupant wears the webbing, and at the webbing pulling out position exceeding the webbing maximum unwinding position after the predetermined time, the elastic body The first scope of claims for utility model registration that suppresses the urging force of
The webbing take-up force suppressing device described in 2.
