Abstract: A side airbag apparatus is mounted on a vehicle having a body and a seat on which an occupant is seated. The seat includes a seat section and a backrest section. A passenger compartment is defined in the body. The apparatus includes a first side airbag and a second side airbag. The first side airbag is deployed and inflated between the occupant and a sidewall of the passenger compartment to correspond to a body part of the occupant that includes a lumbar region. The second side airbag is deployed and inflated between the first side airbag and the sidewall of the passenger compartment to correspond to the lumbar region. Thus, when the airbags are deployed and inflated, the lumbar region of the occupant is pushed so that the entire body of the occupant is moved toward the center of the passenger compartment.

Abstract: In a head protection air bag device, a folded air bag receives inflation gas, and when its inflating operation is completed, inflation parts of front and rear inflatable protective shielding parts as partitioned by partitioning parts generate tensions in the longitudinal direction in the front and rear inflatable protective shielding parts per se. The front and rear inflatable protective shielding parts are interconnected to each other by inflation communicating part under a plate-like portion which blocks the inflow of the inflation gas, at the lower fringe side of the air bag. The inflation communication parts are longitudinally disposed along the lower fringe side of the air bag. Therefore, the front and rear inflatable protective shielding parts are interconnected without reducing the tensions in those parts. As a result, a high tension having the longitudinal direction is generated in the entire lower fringe of the air bag.
