Seat Belt Webbing Elongation Testing

Polyester seat belt webbing elongation tests were performed at the University of California, Santa Barbara. A constant webbing grip separation rate of 2.0in/min was maintained by a Material Test System 810 tension-compression machine. A 5,000lb rated load cell was used. Webbing elongation was measured by an EIR laser extensometer.

Parameters Measured:

  • Webbing pre-load force
  • Webbing tension force
  • Webbing grip separation
