Occupant safety restraint system

An occupant safety restraint system, comprising:

• a seat structure defining a seat back and a seat bottom;
• the seat back including one or more belt slots, each belt slot of the one or more belt slots receiving a restraining belt passing through the belt slot to a forward side of the seat back;
• each belt slot of the one or more belt slots associated with a deformation member over which the restraining belt passes as the restraining belt passes through each of the pair of belt slots;
• and
• each deformation member having a leading end projected from a respective belt slot and a trailing end connected to the seat back at a respective belt slot, wherein when a force is applied to the deformation member by the restraining belt during a movement of the seat structure, the leading end of the deformation member deforms toward the trailing end of the deformation member to absorb energy being applied to the deformation member by the restraining belt.
