Occupant protection apparatus
View Patent ↗An occupant protection apparatus protects an occupant sitting on a seat adjacent to a side door of a vehicle when a side collision or a rollover occurs. The occupant protection apparatus includes a push-up device for pushing up a part of a hip portion of the occupant adjacent to the side door when the side collision or the rollover occurs. In the occupant protection apparatus, when the side collision of the vehicle occurs, the push-up device pushes up the part of the occupant's hip to tilt an upper body of the occupant away from the side door. It is preferable that the push-up device includes an inflatable bag and a gas generator for inflating the bag.
1. An occupant protection apparatus for protecting an occupant, comprising:
a seat situated adjacent to a side door of a vehicle,
push-up means disposed inside the seat and including an inflatable bag situated at a door side of the seat and a gas generator attached to the inflatable bag for inflating the same, said inflatable bag being provided less than a half of the seat in a width direction of the seat to be inflated by the gas generator for pushing up a part of a hip portion of the occupant adjacent to the side door, said seat being inclined upon inflation of the inflatable bag such that the door side is located higher than an opposite side thereof in the width direction to form a greater space between the side door and the occupant when a side collision or a rollover occurs, and
an airbag disposed inside the vehicle for expanding in the greater space between the side door and the occupant created by the push-up means when the side collision or the rollover occurs.
2. An occupant protection apparatus for protecting an occupant, comprising:

an airbag disposed inside the vehicle for expanding in the greater space between the side door and the occupant created by the push-up means when the side collision or the rollover occurs.
3. An occupant protection apparatus according to claim 2 , wherein said airbag is at least a side bag or a curtain bag.
