ATASA 5 th Restraint Systems Officially called SPR4 (Snake Pretensioner Retractor), the system comprises a plastic piston instead of conventional metal components to transfer tensioning torque, this meaning in turn that a simpler and lighter weight design has been achieved.
"The pyrotechnical seat belt pretensioner has been an established product for nearly 30 years, but TRW has taken this concept to a new level,” said Harold Lutz, director engineering, TRW seat belt systems.
