The device comprises a rotatable winding body for unwinding and winding the one or more lines, in that the line(s) is/are guided from the first fixed connection point in a first sub-portion from a stationary first position coaxial with the winding body to a second position opposite the first position and from said second position to a third position which is substantially in one plane with the first position but is rotatable with the winding body, the line(s) in the first sub-portion being guided helically at least in portions.

Abstract: In a pretensioner mechanism of a webbing take-up device, a sealing member seals a communicating hole of a piston. When a force limiter mechanism is operated and rotating of a spool in a pull-out direction is allowed, the piston is moved to an upper side in a state in which the sealing member is pressed and contacted against a cylinder. As a result, the sealing member is turned and the sealing of the communicating hole by the sealing member is released. In consequence, a number of components may be reduced and assembly characteristics of the pretensioner mechanism may be improved.
