Abstract
An air bag including a first panel, a second panel opposed to the first panel, and a third panel cooperating with the first and second panels to define an opening in the vicinity of one end portion of the air bag that serves as a starting point for deployment. The first and third panels are connected with each other along entire outer peripheries thereof except around the opening of the air bag. The second and third panels are connected with each other along entire outer peripheries thereof except around the opening. The air bag is disposed at a folded state behind a back of an occupant and deployable between the occupant and an inside surface of a side of a vehicle compartment so as to cover a side of the occupant.
Claims20
An air bag for a vehicle, the air bag being deployable from one end portion thereof as a starting point for deployment along an occupant of the vehicle, the air bag comprising:
- a first panel adapted to be opposed to the occupant;
- a second panel opposed to the first panel;
- and
- a third panel cooperating with the first and second panels to define an opening in the vicinity of the starting point for deployment,
- wherein the first and third panels are connected with each other along entire outer peripheries thereof except around the opening of the air bag, and the second and third panels are connected with each other along entire outer peripheries thereof except around the opening.
An air bag apparatus for a vehicle, the air bag apparatus being useable within a compartment of the vehicle, the air bag apparatus comprising:
- an air bag deployable from one end portion thereof as a starting point for deployment along an occupant of the vehicle, the air bag including a first panel adapted to be opposed to the occupant, a second panel opposed to the first panel, and a third panel cooperating with the first and second panels to define an opening in the vicinity of the starting point for deployment, the first and third panels being connected with each other along entire outer peripheries thereof except around the opening, the second and third panels being connected with each other along entire outer peripheries thereof except around the opening;
- and
- an inflator that supplies gas to the air bag,
- wherein the air bag is disposed at a folded state behind a back of the occupant and deployable between the occupant and an inside surface of a side of the compartment so as to cover a side of the occupant when the gas is supplied to the air bag.
An air bag apparatus for a vehicle, comprising:
- an air bag deployable from one end portion thereof into a flat box-shape along a side of an occupant of the vehicle, the air bag being formed by a first panel, a second panel opposed to the first panel and a third panel interposed between the first and second panels and cooperating with the first and second panels to define an opening, the first and third panels being connected with each other along entire outer peripheries thereof except around the opening, the second and third panels being connected with each other along entire outer peripheries thereof except around the opening;
- an inflator disposed inside the one end portion of the air bag, the inflator supplying gas to the air bag;
- and
- fixing means for fixing the air bag with the inflator to a vehicle body,
- wherein the air bag includes a fold-fixed portion that is folded to block fluid communication between an inside of the air bag and an outside thereof through the opening and fixed to the vehicle body by the fixing means.
