The present invention provides a module for stacking thin panels and a method of stacking thin panels when a plurality of thin panels are vertically stacked in a state of being supported by the modules capable of securing an adequate load transfer area for transferring a load of the thin panels. The module for stacking the thin panels includes drop-off preventing means for regulating horizontal movement of the thin panel including a protrusion portion protruding downward from a lower portion of the module. When an upper module is stacked on a lower module such that a load releasing surface of an upper module is placed on a load receiving surface of a lower module, an outer surface of the protrusion portion of the upper module abuts on an upper inner surface of the lower module from an inner side thereof.

An improved occupant restraint system is provided which includes a torso support unit that provides external support to an upper torso of an individual, who may be the occupant of a vehicle exposed to upward acceleration events. The torso support system provides support to the occupant's upper torso including rib cage, arm pit, upper arm and/or shoulder region. This support can be accomplished by one or more straps, one or more bars, one or more hooks or any other support device(s) that are connected to structure of the vehicle, such as a seat or standing platform, and in turn connected to the upper torso of the occupant to transfer upward vehicle forces to various parts of the upper torso independently of the forces transferred to the lower body such as the feet, legs and seat through other vehicle structure. With such a torso support system, when an upward acceleration event occurs, the compressive forces impinging on the occupant's spinal column are reduced wherein the likelihood of occupant paralysis or death due to spinal and other acceleration-induced injuries are significantly reduced.
