ABSTRACT:
When a tensile force of at least a predetermined value is applied to a webbing, a webbing retractor allows the webbing to extend over a length increased beyond that available from mere tightening of the webbing wound on a take-up spindle by the tensile force. The retractor includes a base; the take-up spindle carrying the webbing fastened at one end thereof to the take-up spindle; a lock device for locking rotation of the take-up spindle in a webbing-releasing direction; and a webbing-extension increasing member capable of undergoing a deformation or collapse in a transmission route of the tensile force from the take-up spindle to the base upon application of the tensile force subsequent to locking of the take-up spindle by the lock device.
