Provided is an airbag and an airbag apparatus that are easy to manufacture and in which the amount of gas to be released from the inside of the airbag when a passenger in proximity is restrained can be increased. An airbag includes a first panel member provided on an instrument-panel side, and a second panel member provided on a passenger side. The first panel member includes a deploying part that is deployable into a tapered cylindrical shape whose diameter increases toward the distal side thereof. The second panel member has on the proximal side thereof a fitting port whose diameter is smaller than the maximum diameter of the deploying part. In a state where the airbag has been inflated, the fitting port is anchored to the deploying part. If a passenger in proximity is restrained, gas is releasable from a clearance.

Provided are a pretensioner, a retractor, and a seat belt device in which strength and slidability of a rod-shaped power transmission member may both be achieved. A pretensioner 3 includes a ring gear 31 on which the spool 2 is rotatably disposed, and power transmission units 32 for transmitting power to the ring gear 31 in an emergency. The power transmission units 32 includes a rod-shaped power transmission member 32a for transmitting power to the ring gear 31 while being plastically deformed, a tip reinforcing member 32b disposed on a tip side of the power transmission member 32a, a pipe 32c for containing the power transmission member 32a, and a gas generator 32d disposed at an end of the pipe 32c. The tip reinforcing member 32b has higher strength than the power transmission member 32a.

A buckle includes a pair of power terminals; an occupant detection unit to detect an occupant on a seat of a vehicle; and a switch to permit supplying power from the power terminals to the occupant detection unit in an unfastened state of a seat belt. The occupant detection unit changes a value of a current flowing in the power terminals, between a detected state in which the occupant is detected in the unfastened state, and a non-detected state in which the occupant is not detected in the unfastened state. The switch inhibits supplying power from the power terminals to the occupant detection unit in a fastened state of the seat belt, to make the current value in the fastened state lower than the current value in the detected state, and lower than the current value in the non-detected state.

Provided are a seat belt retractor and a seat belt device with which it is possible to improve energy absorption characteristics and a restraining property. The seat belt retractor includes a spool 2 that performs winding of a webbing W for restraining an occupant, a shaft 3 inserted through an axial center of the spool 2, and a locking base 4 connected to the shaft 3 and capable of switching between a rotating state and a non-rotating state. The seat belt retractor further includes a load adjustment member 5 disposed between the shaft 3 and the locking base 4 and that blocks or reduces load transmission in a case where a load equal to or greater than a threshold is applied to the shaft 3, and an energy absorption device 6 disposed between the spool 2 and the locking base 4 and capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the locking base 4. The energy absorption device 6 is connected in parallel with the load adjustment member 5.

Provided are a seat belt retractor and a seat belt device with which it is possible to improve an occupant-restraining property and energy absorption characteristics. A seat belt retractor 1 including a spool 2 that winds up a webbing W for restraining an occupant, a shaft 3 inserted through an axial center of the spool 2, and a locking base 4 connected to the shaft 3 and capable of switching between a rotating state and a non-rotating state, further includes an energy absorption device 5 capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the shaft 3, and a load adjustment member 6 that blocks or reduces load transmission when a load equal to or greater than a threshold is applied to the shaft 3 or the spool 2. The spool 2, the shaft 3, the locking base 4, the energy absorption device 5, and the load adjustment member 6 are serially connected.

Provided is a vehicle occupant restraint device including an airbag (20) that is provided in a shoulder belt position of a seat belt while being folded in a belt-like shape to be capable of inflating upon receiving a predetermined actuating signal, the seat belt being wound by a single winding device. The airbag (20) is folded to surround a slide guide (30) including a hard member (31) having seat-belt passing portions arranged at predetermined intervals in an insertion direction of webbing (W) and a soft member (32) supporting the hard member (31). The airbag (20) smoothly slides along the webbing (W) through the slide guide (30) when the seat belt is pulled out.

Provided is a side air-bag device in which a large quantity of gas can be supplied to the upper part of an air-bag without modifying the position and direction of mounting of an inflator to a seat-back frame. The side air-bag device includes an air-bag 20, a partition panel 24 that partitions an interior of the air-bag 20 into at least two chambers, an upper chamber and a lower chamber, a cylindrical guide cloth 30 disposed in a vertical direction in the air-bag20, and an inflator 1 disposed in the guide cloth 30 and having a gas ejection opening 1a at a lower end. The guide cloth 30 is open at a top, closed at a bottom, and has a gas outlet 30a at a side near a lower part.
