Abstract
An air belt device includes a shoulder belt section that is worn from a shoulder on one side in a seat width direction to a lumbar on another side in the seat width direction of a passenger, who is seated on a seat. The shoulder belt section includes an inflation section that is inflated by a supply of gas and in which a portion on a head side of the passenger with respect to a center section in a width direction of the shoulder belt section is deployed to be larger than a portion on an opposite side from the head side.
Claims13
An air belt device comprising:
- a shoulder belt section that is worn from a shoulder on one side in a seat width direction of a passenger who is seated on a seat to a lumbar on another side in the seat width direction, wherein
- the shoulder belt section includes an inflation section that is inflated by a supply of gas and in which a portion on a head side of the passenger with respect to a center section in a width direction of the shoulder belt section is deployed to be larger than a portion on an opposite side from the head side,
- the inflation section includes a tether that restricts an inflation thickness more on the opposite side from the head side than on the head side, and
- the tether is provided on the head opposite side with respect to a center line in a folded state of a bag and connects between base clothes that face each other.
An air belt device comprising:
- a shoulder belt section that is worn from a shoulder on one side in a seat width direction of a passenger who is seated on a seat to a lumbar on another side in the seat width direction, wherein
- the shoulder belt section includes an inflation section that is inflated by a supply of gas and in which a portion on a head side of the passenger with respect to a center section in a width direction of the shoulder belt section is deployed to be larger than a portion on an opposite side from the head side,
- the inflation section includes a bag that is inflated from a folded state by the supply of the gas and a tether that restricts an inflation thickness on the opposite side from the head side,
- a peripheral length of a portion of the bag that is deployed on the head side with respect to the tether in the width direction of the shoulder belt section is longer than a peripheral length of a portion thereof that is deployed on the opposite side from the head side with respect to the tether in the width direction of the shoulder belt section in a cross-sectional view that is orthogonal to a longitudinal direction of the shoulder belt section in the folded state,
- the bag has a middle folded section that is folded inward to a center side in the width direction of the shoulder belt section from the head side, and
- an end on the head side that includes the middle folded section is sewn at a tear seam that is torn by inflation pressure of the bag.
An air belt device comprising:
- a shoulder belt section that is worn from a shoulder on one side in a seat width direction of a passenger who is seated on a seat to a lumbar on another side in the seat width direction, wherein
- the shoulder belt section includes an inflation section that is inflated by a supply of gas and in which a portion on a head side of the passenger with respect to a center section in a width direction of the shoulder belt section is deployed to be larger than a portion on an opposite side from the head side,
- the inflation section includes the bag that is inflated from the folded state by the supply of the gas,
- a peripheral length of a portion of the bag that is deployed on the head side with respect to the center section in the width direction of the shoulder belt section is longer than a peripheral length of a portion thereof that is deployed on the opposite side from the head side with respect to the center section in the width direction of the shoulder belt section in a cross-sectional view that is orthogonal to a longitudinal direction of the shoulder belt section in the folded state,
- the bag has a folded back section that is folded back to the center section in the width direction of the shoulder belt section from the head side,
- the inflation section includes a cover member that covers the bag and has a torn section in which a portion in a peripheral direction is torn by inflation pressure of the bag,
- a tether is provided entirely on the opposite side from the head side with respect to a center line in a folded state of a bag and connects between base clothes that face each other, and
- the inflation section is provided on a webbing that constitutes the shoulder belt section.
An air belt device comprising:
- a shoulder belt section that is worn from a shoulder on one side in a seat width direction of a passenger who is seated on a seat to a lumbar on another side in the seat width direction, wherein
