This invention provides a gas generation agent composition shape formation body used for the air bags. It makes the air bag's initial inflation speed slower than that of the prior art, and thus the initial force of the air bag's inflation will not be harmful to the passenger. And meanwhile, after 35 to 50 milli seconds, it can maintain sufficient energy to restrict the passenger. The shape formation body, which is made of the non-azido gas generation agent composition. It is of porous shape. The length of the porous shape formation body is L(mm), the inner diameter (d) of the holes of the shape formation body is d(mm), the value of d is 0.2-1.5 (mm), and the value of L/d is above 1.5. |
