A webbing pull-in device has a take-up shaft at which a webbing can be pulled in due to the take-up shaft being operated, a first pulley that is rotated at a time of an emergency of a vehicle, and a second pulley that, by being rotated, operates the take-up shaft. Further, the webbing pull-in device has a connecting wire that connects the first pulley and the second pulley, and that, by being taken up onto the first pulley at a time when the first pulley is rotated, transmits rotational force of the first pulley to the second pulley.

Webbing pull-in device

An air belt device is provided with a webbing that is fitted around a vehicle occupant who is sitting in a vehicle seat, and an airbag portion that is provided in parallel with the webbing and is inflated and deployed when gas is supplied to an interior thereof. The airbag is provided with a reference portion that forms a portion of the airbag and is formed as a result of the airbag being folded. The airbag is also provided with a slack portion that forms another portion of the airbag and is formed as a result of the airbag being folded, and that extends in parallel with the reference portion and whose dimension in the transverse direction of the webbing is set longer than a dimension in the transverse direction of the webbing of the reference portion.

Air belt device

In a seatbelt device, at a time of an emergency of a vehicle, gas is supplied via a tube interior into a chest bag, and the chest bag is inflated and expanded. Here, the tube is disposed at a thickness direction one side of a webbing at positions at which a lap webbing, at a thickness direction other side thereof, is interfered with by a seat cushion and a passenger. Therefore, the tube being crushed by the seat cushion and the passenger, and the lap webbing, can be suppressed, and supplying of gas via the tube interior into the chest bag being limited can be suppressed.

Webbing device

In a seatbelt device, at a time of an emergency of a vehicle, gas is supplied into a tube, and gas within the tube is supplied into a chest bag of a bag, and the chest bag is inflated and expanded. Here, at a time when gas is supplied into the tube, due to the tube being inflated between a webbing and a lower side peripheral surface of an insert-through hole of a tongue, a transverse direction other side portion of the bag is crushed by the tube, and gas that is within the chest bag passing via the transverse direction other side portion of the bag into a waist bag of the bag is limited. Therefore, the chest bag can be inflated and expanded at an early stage.

A seatbelt device is provided with a webbing and a bag body. The webbing is applied to the body of a vehicle occupant. The bag body includes a first layer at a webbing side and a second layer at an opposite side from the webbing, with the first layer disposed therebetween. The bag body is provided along a length direction of the webbing, fixed to one side of a thickness direction of the webbing and supported by the webbing, and disposed between the webbing and the body of the vehicle occupant in a state in which the webbing is applied to the body of the vehicle occupant. The bag body is inflated by fluid being supplied thereinside. A joined portion at which the first layer and second layer are locally joined together is formed in the bag body. The inflation of the bag body is controlled by the joined portion.

Seatbelt device

A seatbelt device comprises a webbing, a bag body and an anchor member. The webbing is applied to the body of a vehicle occupant sitting on a seat. The bag body is provided along a length direction of the webbing, and the bag body is disposed at one side of the webbing and can be inflated by pressure of a fluid supplied from a length direction one side of the bag body. A deployment portion through which the fluid can pass is provided in the bag body, being disposed at width direction outer sides and a thickness direction another side of the webbing. An insertion hole is formed in the anchor member, through which the webbing and the bag body are inserted. The webbing is folded at the thickness direction one side when applied to the body of the sitting vehicle occupant, and the deployment portion of the bag body is disposed in the insertion hole.
