ABSTRACT:
A safety belt wind-up device includes a rotatable belt wind-up shaft, wind-up force lock device capable of assuming interlocked and uninterlocked positions with the wind-up shaft including a first member rotatively driven by the wind-up shaft when the wind-up force lock device is in the interlocked position, a first cam rotating together with the first member, a second member rotatively driven by the first member engaging the second member, and a second cam rotating together with the second member, and a device for bringing the lock device into the interlocked and uninterlocked positions depending upon engagement and disengagement of a buckle of the device. The device permits a safety belt to be drawn out of the device to a length required for a user's action from the equipped position and completely delete the wind-up force acting upon the belt at the equipped position, whereby the user is not subjected to a belt wind-up force.
