The Linear Side-impact Protection (L.S.P. System) provides extra safety in the event of a side-impact collision. The Linear Side-impact Protection System (L.S.P. System) systematically absorbs the force of a side-impact collision in a linear series of reactions through the use of the shoulder and head protectors. At the same time, the body’s kinetic energy caused by the impact is absorbed at a very early stage and the head is actively led into a safe position.
