Laminated vehicle airbag cover, for protecting vehicle occupants during collisions

摘要: The cover comprises a main component of laminated layers (10,12) made from material selected elastomeric alloys thermoplastic polymer with non, partially or fully crosslinked EPDM (ethylene propylenediene rubber) terpolymer, block copolymers alternating polyester and polyether blocks PS(polystyrene) polyolefins. has deliberate weak failure line(18) which tapers the inner towards outer side wall leaves remaining thickness 0.3-1mm between line tip wall. In process for manufacture is created on by laser whose focussed beam higher energy density in centre.
