Abstract

A buckle tensioner for pre-tensioning a safety belt band comprises a traction transmission device engaging on a belt buckle, a motor and a pressure storing device which is able to be compressed by means of the motor. The traction transmission device is coupled in a force-fitting manner to the pressure storing device and the pressure storing device is arranged such that an expansion of the pressure storing device brings about a pulling away of the belt buckle for tensioning the safety belt band.
