With vehicles which do not have a back panel behind the seats the metal structure is free and in the event of a crash loads can shoot through the seat and injure the passengers.
The mission is to find a special arrester for loads:
- It must be very light and slim
- It must be possible to incorporate it into the metal structure
- It must withstand a very great force without tearing (UTS > 900 N) and it must not damage the fabric.
The very robust fabric tape is cut to length, perforated, affixed with a metal bracket, which is then sewn into the turned over flap of the tape.
- Vehicle seats
- Protection from loads
