A retractor of a seat belt apparatus includes a spool that is configured to wind the seat belt while allowing the seat belt to be pulled out, a motor that includes a shaft coupled to the spool and generates a rotational resistance force against the spool rotating in a direction to pull out the seat belt, the rotational resistance force corresponding to the rotation of the spool and the shaft caused by pulling out of the seat belt, a rotational resistance member that is coupled to the spool and generates a rotational resistance force against the spool rotating in the direction to pull out the seat belt when the seat belt is pulled out in the event of vehicle collision, and a reducing mechanism that reduces the rotation of the spool and transmits a reduced rotation to the shaft.

Vehicle seat belt apparatus

A development restricting member is configured to include a fixing section attachable to a body of a vehicle above the pillar garnish, a holding section opposing to the fixing section, and a middle connecting section connecting a lower end part of the fixing section and a lower end part of the holding section, wherein an upstanding section is provided in a middle part of a base end part and a top end part of the holding section to extend toward the fixing section, so that a folded curtain airbag is housed so as to be surrounded by the fixing section, the holding section, and the upstanding section.

Member for restricting expansion of curtain airbag and structure of portion where curtain airbag is mounted

The operation efficiency is improved by enabling a gas rectifying member of an airbag device to be easily disposed in a folded airbag. An airbag in a folded state is accommodated around an inflator of an airbag device, and a gas rectifying member () for guiding gas is disposed between the airbag and the inflator surrounded by the airbag. The gas rectifying member () includes a retained portion (A) retained, together with the airbag, around the inflator and a free-standing tubular gas-flow guide portion (B) standing upright from the retained portion (A), which are formed as a single part from a base fabric. The airbag is folded in a state in which the retained portion (A) is retained inside the airbag. At this time, the gas-flow guide portion (B) is less likely to be sandwiched between the airbag, because it is standing in the airbag.

Airbag device

There are provided an airbag folding device, and an airbag folding method, for mechanically folding an airbag to form a doughnut-shaped airbag. The airbag folding device is characterized in comprising a support member () columnar in shape, rising while supporting a tubular tether belt (), an outer cylinder () coaxial with the support member (), for containing the airbag body () on the outside of the support member (), by rising, a work table () having the support member (), and the outer cylinder (), and a clamping member () positioned straight above the support member (), for clamping the tubular tether belt () between the clamping member () and the support member (), wherein a pair of plates () in such a state as to cover an upper end of the outer cylinder (), and to be fitted to a lower end of the clamping member () cause the support member (), the outer cylinder () and the clamping member () to concurrently descend.

Airbag folding device and airbag folding method

There is provided an airbag device being excellent in performance of protection of an occupant wherein a folded airbag () undergoes sequential and orderly expansion starting from a region where the expansion ought to be started. It is characterized in that a gas rectification member () for rectifying and guiding a gas generated from an inflator () up to the vicinity of a part of the airbag (), inflating in the initial stage of the expansion thereof, is provided substantially at the central part of the airbag ().

There is provided an airbag device for allowing a holding member to firmly hold an outer circumference part and a peripheral edge part of an airbag during the airbag assembling work and to reduce the assembling work time. The airbag device comprising a holding member () for holding an airbag () in a state as folded and contained therein, and pressing down a side face of the airbag () on the outer circumference thereof. The holding member () is made of a woven cloth, and an anticipated rupture part () to be ruptured by a gas generated from an inflator () is formed at the position corresponding to the part of the airbag (), inflating in the initial stage of the expansion thereof.

It is characterized in that a gas rectification member () for rectifying and guiding a gas generated from an inflator () up to the vicinity of a part of the airbag (), inflating in the initial expansion thereof, is provided substantially at the central part of the airbag ().

The invention improves efficiency in a work for assembling an airbag device () with an airbag cover (). A peripheral edge of the inflator attachment opening of the airbag () is secured to a cushion ring (), the airbag () integrally connected to the tip and a rear end of the tubular tether belt () is extended to its full and then pulled back thereby folding back the airbag () around the tubular tether belt () and folding the tubular tether belt () and the airbag () while being pulled back. Then, the tip of the tubular folded tether belt () is secured to a central part of the back side of the airbag cover () for containing the airbag () therein.

Method of assembling airbag device and airbag device

There is provided an airbag device comprising electrical equipment disposed at the central part of a steering wheel, capable of connecting a harness to the electrical equipment while using the steering shaft, the inflator, and so forth, commonly in use, thereby alleviating work for manufacturing intricate components, and achieving reduction in component cost. The airbag device comprises an airbag cover () for housing an airbag () folded substantially at the central part of a steering wheel (R), and electrical equipment (M) disposed at a recessed part () of the airbag cover (), wherein a backside of the recessed part () of the airbag cover () is covered with a fixed end portion of a tubular tether belt () for constraining a distance up to which the airbag undergoes inflation and expansion, and a harness () is inserted into a harness insertion hole () provided at the fixed end portion, the harness being connected to an electrode member of the electrical equipment (M).
