Use of Wires in Restraining Test Cushions

• Chapter 7 Supplement (7.3.5) discusses the use of
  one wire in securing the vertical seat cushion to
  the specimen frame.
• The survey of labs above shows that multiple
  wires are being used not only on the vertical
  cushion, but the horizontal cushion as well.
• Full-scale testing of both restrained and
  unrestrained leather seats is being considered at
  the Tech Center.
