**5.1 New restraint concepts**

First of all, design guidelines for new restraint devices were defined specifically for the side-facing occupant. The requirements for the restraints' performances are such that: 1) the pelvis lateral movement should be restrained earlier and properly; 2) the head/torso lateral displacements should be minimized to prevent the head/torso contact to any laterally nearby objects; 3) the lower legs/foot lateral failing motion and impact to the 2nd row LHS seat should be minimized.

Four new restraint concept designs highlighted below were developed:
