Rotary seatbelt pretensioner

  • 30-Aug-2013 06:39 EDT

TRW Automotive’s new anchor seatbelt pretensioner in a rotary configuration features a lightweight design and compact packaging for easy integration in vehicle interiors. With TRW’s APR1, there is no linkage element necessary and only the normal seatbelt webbing will be visible in the vehicle cabin. The device is designed to deliver pretensioning forces of more than 3 kN (674 lb), which can help to remove seatbelt slack within milliseconds of a crash being detected. The APR1 device helps form the basis of TRW’s advanced adaptive occupant technologies designed to help manage occupant energy in an unavoidable crash scenario. For example, it can be combined with the supplier’s active control retractor system or active buckle lifter.
