Vehicle occupants protection system

A vehicle occupants protection system comprising:

• a pillar garnish mounted on a passenger compartment side of a pillar which supports a roof to define a predetermined amount of a space portion between said pillar and said pillar garnish;
• a roof side airbag accommodated in said space portion, said roof side airbag being inflated by gas generated when an impact of a predetermined magnitude or more is applied to a side of a vehicle so as to expand into a passenger compartment of said vehicle while forcibly opening one end portion of said pillar garnish;
• and
• a small impact absorbing member joined to said pillar garnish at a bottom surface thereof so as to be accommodated in said space portion, said small impact absorbing member absorbing an impact of such a small magnitude that said roof side airbag remains unopened,
• wherein a joining force at a portion of said bottom surface of said small impact absorbing member which is located closer to said roof side airbag is set smaller than a joining force at a portion of said bottom surface of said small impact absorbing member which is located farther away from said roof side airbag, said joining force so set smaller being a force which is so weak that said pillar garnish is allowed to separate from said bottom surface of said small impact absorbing member when said pillar garnish is deformed.
