Abstract
A vehicle occupant restraining device, comprising: a pair of air bags; an inner bag housed in at least one of the pair of air bags, is in communication with the at least one of the air bags, and is inflated and deployed inside the at least one of the air bags, on the sides of the body of a vehicle occu-pant; and a pair of pieces of tension cloth housed so as to extend along the respective sides of a housed pair of air bags, which are located on the opposite sides of the vehicle occupant, and then through the inside of the seat back of a seat into a seat cushion, wherein the inner bag completes inflation and deployment before the at least one of the air bags does, and the pair of pieces of tension cloth is deployed on the sides of the seat.
Claims12
An occupant restraining device for restraining an occupant sitting on a seat of a vehicle, comprising:
- first and second airbags stowed in opposite sides of a seatback of the seat that inflate and deploy respectively from both lateral sides of the seatback;
- an inner bag that is stowed inside the first airbag and is connected to the first airbag, the inner bag configured to expand and deploy inside the first airbag;
- and
- first and second tensile cloths stowed from within the seatback of the seat to within a seat cushion of the seat along an outer facing side of the first and second airbags, respectively;
- wherein
- wherein the inner bag completes expansion and deployment prior to the first airbag,
- wherein the first and second tensile cloths are deployed along the outer facing sides of the first and second airbags, respectively by expansion and deployment of the first and second airbags, and are stretched from the seatback to the seat cushion to retain a surface of both of the first and second airbags, and
- wherein a front end of the inner bag is arranged at or behind a position overlapping the first tensile cloth in a side view and the first tensile cloth downwardly extends across the first airbag along an arcuate path in the side view when the first airbag is expanded and deployed.
An occupant restraining device that restrains an occupant sitting on a seat of a vehicle, the occupant restraining device comprising:
- first and second airbags stowed in opposite sides of a seatback of the seat that inflate and deploy respectively from both lateral sides of the seatback;
- a partition wall arranged inside the first airbag and separating the first airbag into front and rear portions;
- a connecting hole formed in the partition wall;
- and
- first and second tensile cloths stowed from within the seatback of the seat to within a seat cushion of the seat along the side of the pair of airbags
- wherein
- the first airbag completes expansion and deployment of a first space behind the partition wall before a second space in front of the partition wall, and
- wherein the first and second tensile cloths are deployed along lateral sides the seat on outwardly facing sides of the first and second airbags, respectively, and are stretched from the seatback to the seat cushion to retain a surface of the each of the first and second airbags, and
- wherein the partition wall is arranged at or behind a position overlapping the first tensile cloth in a side view and the first tensile cloth downwardly extends across the first airbag along an arcuate path in the side view when the first airbag is expanded and deployed.
