  • (1) The holder holding the inflator is fixed to an opposing portion at the edge of the opening of the first housing in the chamber.
  • the chamber is opened, that is, when the second housing is removed from the first housing, the opening of the first housing is opened. Therefore, the holder fixed to the edge of the opening is also opened to the outside.
  • the inflator can be easily and quickly attached to and detached from the holder opened to the outside in this way.
  • a configuration is adopted in which the holder is fixed to the edge of the opening of the first housing. As a result, the inflator is substantially directly supported by the housing via the holder. Since the housing, including the edge of the opening, has essentially higher mechanical rigidity than a shelf or the like that is retrofitted to the housing, it is easy to ensure durability.
  • the chamber includes the first and second housings, and takes a state in which both are closed and a state in which both are open. When both are closed, the inflator explodes in it. Install and remove the inflator with both open.
  • the opening / closing mechanism between the first housing and the second housing is not particularly limited, and in the embodiment, one edge of both is hinged.

  • a third housing may be included in the components thereof.
  • the opening of the first housing to which the holder is fixed is open upward. This is because the work of installing and removing the inflator becomes easy. It is not unavoidable that the open portion of the first housing is opened laterally or downward. Since the edge of the opening of the first housing supports the holder, it is preferable to form a material having high strength and mechanically having high strength in the structure. With the holder fixed to the edge of the opening of the first housing, the edge of the opening of the second housing can be airtightly overlapped with respect to the holder.

  • the holder can be arbitrarily designed according to the type of inflator.
  • the inflator can sometimes explode abnormally, which can cause the holder to deform. Therefore, the holder is detachably fixed to the edge of the opening and the flange.

  • the third aspect of the present invention is defined as follows. That is, the chamber in a state where the first and second housings are sealed is a covered cylinder. According to such a configuration, by adopting the tubular shape, a large number of inflators can be set so as to cross the shaft of the cylinder. Further, by making it cylindrical, the portion facing the inflator becomes arcuate in the axial direction of the inflator. Therefore, the pressure of the gas injected from the inflator is evenly applied to the portion. Also, the applied force is not dispersed and concentrated on the arcuate peripheral wall. Therefore, its durability is improved.
  • the fourth aspect of the present invention is defined as follows. That is, in the inflator processing apparatus specified in the first to third aspects, the holder releases the gas outlet of the inflator held by the holder. According to such a configuration, there is no element in the holder facing the gas ejected from the gas outlet of the inflator during the inflator treatment. Therefore, the gas ejected from the inflator is diffused in the chamber without being blocked by the holder. As a result, even when the inflator explodes abnormally, the explosive pressure does not directly act on the holder.

According to such a configuration, since a plurality of holders are provided side by side and a separator is provided between the holders adjacent to each other, the gas ejected from the inflator when the inflator held in one holder is processed is adjacent to each other. It is possible to prevent a situation in which the inflator held in the holder is linearly and carelessly interfered with. In particular, when an inflator explodes abnormally, it is possible to prevent the influence from affecting the inflator installed next to it.
