An airbag is provided which securely prevents gas leakage through seams between panels and has excellent productivity. The airbaghas panels. Peripheral portions of the panelsare bonded with silicone adhesiveand also sewn together by sewing yarnsA,B. Seams of the sewing yarnsA,B may be coated by silicone sealant. The sewing yarnA composing an inner seam is thinner than the sewing yarnB composing an outer seam so that the sewing yarnA is broken during the inflation of the airbag, thereby absorbing energy.

A tongue assembly for a seat belt device has a tongue body formed in a plate shape having a first slit through which a belt webbing extends, and a locking plate having a second slit through which the belt webbing extends. The tongue body has a front end portion thereof as an insertion portion to be inserted into a buckle. The first slit is formed in a rear portion of the tongue body and extends in the lateral direction perpendicular to the longitudinal direction of the tongue body. The locking plate is disposed to face a surface of the tongue body rearwardly away from the first slit, further extends rearwardly away from a rear edge of the tongue body, and has a front end supported to the tongue body to allow pivotal movement of the locking plate in a direction that a rear end portion thereof freely leaves from or approaches the tongue body. The second slit is formed in a rear portion of the locking plate and extends in the lateral direction. The locking plate is provided with a cutout connecting the second slit with the rear edge of the locking plate.

Tongue assembly for seat belt device

A seat belt retractor for an automobile comprises a reel for retracting a seat belt around the same, a frame for holding the reel in a rotatable manner, and a spring for biasing the reel in the direction of retracting the belt. The spring is consisted of a main spring for normally biasing the reel in the direction of retracting the belt and an auxiliary spring for producing, in the direction of retracting the belt, biasing force that is applied to the reel in an off-and-on way by an off-and-on unit, the main spring and the auxiliary spring being disposed in parallel. The device includes a unit for detecting an open/closed state of a door at the side of a seat on which the seat belt is fastened, and the off-and-on unit interrupts transmission of the biasing force in the direction of retracting the belt from the auxiliary spring to the reel when the door open/closed state detecting unit detects the closed state of the door.
