ABSTRACT:
A rotational tensioning device for a safety belt of a motor vehicle has a reeling device with reeling shaft and a drive wheel connected to the reeling shaft. The drive wheel has a circumference with semi-spherical recesses. A channel, having a first and a second end, is positioned in a plane parallel to the drive wheel. It extends at least over a portion of the circumference of the drive wheel. Spherical mass bodies are contained in the channel. A gas generator is connected to the first end of the channel, wherein, upon activation of the gas generator, a gas is released into the channel for accelerating the spherical mass bodies in the channel and driving the spherical mass bodies through the channel into the semi-spherical recesses to thereby drive the drive wheel and the reeling shaft in a direction of winding of the safety belt. A drive piston, for driving the spherical mass bodies, consists of two of the spherical mass bodies fixedly connected to one another to form a twin ball. The drive piston is positioned within the first end of the channel.
