TRW rolls rotary seat belt pretensioner
There is no linkage element necessary and only the normal seat belt webbing will be visible in the vehicle cabin. It is designed to deliver pretensioning forces of more than 3 kN, which can help to remove some seat belt slack within milliseconds of a crash being detected.
When combined with TRW’s spectrum of occupant protection seat belt and airbag options, the APR1 helps form the basis of advanced adaptive occupant technologies designed to help manage occupant energy in an unavoidable crash scenario. For example it can be combined with TRW’s Active Control Retractor system or Active Buckle lifter, that help to remove some seatbelt slack before a crash occurs if a potential crash is detected by active vehicle sensors.
The APR1 will launch on several European vehicle platforms in 2015.
