Abstract: A system is disclosed for the absorption of an impact, that system comprises a blow molded thermoplastic energy absorbing member. The blow molded thermoplastic energy absorbing member provides opposing first and second walls defining a hollow space; according to one embodiment, a plurality of fused and unfused recessed ribs integrally molded between the first and second walls. The fused recessed ribs have a fused recessed rib end. The fused recessed rib ends are integrally fused to either opposite recessed rib ends or the facing opposite wall at a welded surface such that the height of the recessed ribs from the first wall to the welded surface is about approximately 15.0 to 45.0 mm. The recessed ribs are, according to one embodiment, connected by a plurality of straight interlocking ribs.

Abstract: A system is provided for absorbing energy from impacts to a vehicle, the system comprising: a blow molded energy absorbing member. The member including first and second opposing walls, at least one rib or a pair of ribs disposed between said first and second opposing walls, the rib(s) comprising the first and second opposing walls dented toward other wall with top end part either welded or separated with specified interval. In one embodiment, the energy absorbing member is formed of thermoplastics composed of a polyolefin based resin and 50 to 75% weight of an amorphous resin.

Abstract: A system is disclosed for absorbing impact energy to a vehicle. The system provides first and second blow molded thermoplastic energy absorbing members, each of the energy absorbing member having opposing first wall and a second walls, at least one rib disposed within each energy absorbing member, that rib being integrally molded from at least the first wall. Also provided is a joint whereby the rib attaches to the second wall such that the first and second energy absorbing members absorb an impact energy. The first and second energy absorbing members are aligned such that the impact energy is distributed between the energy absorbing members and is absorbed by the energy absorbing members.
