Abstract
An automotive seatbelt take-up device has a primary spiral spring biasing a take-up shaft in a seatbelt take-up direction. A spring clutch transfers rotation of the take-up shaft in a seatbelt drawing-out direction to a ring. A secondary spiral spring is capable of generating rotational biasing force on the take-up shaft in a direction opposite that of the primary spiral spring. Thus, the present invention provides an automotive seatbelt take-up device that can reduce both the drawing-out force and the take-up force of a seatbelt when the seatbelt is being worn.
