Abstract
An airbag comprises a bag which is bent in the shape of an arrow ′<′ in a deployed state, and a connection member which is arranged on a side of the bag, facing a vehicle body, and connects the upper and lower ends of the bag with each other. A longitudinal intermediate portion of the bag projects toward a vehicle occupant. A space is defined between the projecting intermediate portion and the connection member. The head of the vehicle occupant initially comes into contact with the intermediate portion and then presses the bag toward the vehicle body. Upper and lower parts of the bag which extend upward and downward from the intermediate portion cooperate with the connection member to define a triangular space.
Claims23
An airbag device comprising:
- a side airbag having first and second side surfaces, upper and lower ends and an intermediate portion, the side airbag being configured to deploy downwardly toward a vehicle occupant;
- and
- a member connecting the upper and lower ends of the side airbag,
- wherein the side airbag is configured to inflate into a position wherein an enveloped space is defined by the first side surface and a plane containing the member,
- wherein, after inflation of the side airbag, the member is configured to increase in length if a predetermined level of force is applied to the member, and
- wherein the member comprises a loop part adjacent a tearable portion of the member configured to rupture when the predetermined level of force is applied to the member.

An airbag device comprising:
- a side airbag having first and second side surfaces, upper and lower ends and an intermediate portion, the side airbag being configured to deploy downwardly toward a vehicle occupant;
- and
- a member connecting the upper and lower ends of the side airbag,
- wherein the side airbag is configured to inflate into a position wherein an enveloped space is defined by the first side surface and a plane containing the member,
- wherein, after inflation of the side airbag, the member is configured to increase in length if a predetermined level of force is applied to the member,
- wherein the member has a slit configured to open to a larger area when the predetermined level of force is applied to the member, and
- wherein the slit is initially closed by a tear seam upon inflation of the airbag before application of the predetermined level of force.
