Title: Vehicle safety belt having low stretch plastics coating - which cracks when belt has undergone plastic deformation
Inventor: BERGER JOHANN
IPC: A62B35/00
Filed: 1974-10-01
Abstract: A strap, intended for making a safety belt for automobiles, aircraft or the like has a coating bonded to its surface either all over or locally, of a material which is capable of accepting considerably less strain than the fabric of the belt itself. This coating material may also be a different colour. It may be smoother than the belt fabric and its pref. thickness is 2-150 mu. Since the energy absorption of a safety belt resides in its capacity for deforming considerably but irreversibly, it is important that a belt once used in a crash shall not be used again. By coating it with a matl. which ruptures by cracking or tearing when the belt has been permanently deformed in this way, the belt is readily identifiable as unsuitable for use again. Pref. coating matls. are thermoplastics, esp. polyamide or PVC; duroplastics, esp. epoxy resin, latex mixt. applied as a liq., synthetic paint applied as a liq.
