摘要:
An occupant protection device includes an airbag 10 that is inflated with gas from an inflator 20 at a side of an occupant B to protect the body of the occupant B from the shoulder Ba to the lumbar Bd, the airbag 10 having substantially the same vertical dimension as that of a seat back Aa. In this occupant protection device, uninflatable sections 12 and 13 are formed in a vertical center portion 10c of the airbag 10, that is, at a position corresponding to the chest Bb and the abdomen Bc of the occupant B. Accordingly, a region which is thinner than an upper portion 10a and a lower portion 10b of the airbag 10 in a vehicle width direction when the airbag 10 is inflated and that extends substantially parallel to the seat back Aa is formed substantially at the center of the airbag 10.

A flange is formed at an upper edge of a lower arm, and the strength of an upper portion of the lower arm is set to be greater than the strength of a lower portion thereof. A fragile portion is formed in a longitudinally intermediate portion of the lower arm, and when an impact of a predetermined value or greater is applied in the rearward direction of the vehicle during a rear collision of the vehicle, the lower arm is adapted to absorb the impact by undergoing deformation beginning at the fragile portion. In addition, with respect to the load applied to the seat back from the rear by luggage or the like during a front collision of the vehicle, the deformation of the lower arm can be effectively suppressed by the flange.

An objective is to inflate an inflation portion to an upward position, corresponding with a temple area of an occupant, at the time of a side impact. At a shoulder portion of a seatback 26 of a vehicle seat 12, there is an inflation-time cross-sectional shape regulation component 22, through which an occupant restraint webbing 16 passes. The occupant restraint webbing 16 has an inflation portion 18 that corresponds with a cephalic region 14H of an occupant 14 at the time of inflation. At the time of inflation of the inflation portion 18, the inflation-time cross-sectional shape regulation component 22 regulates such that a cross-sectional shape of the inflation portion 18 is an oblong shape which is long in a vertical direction. Therefore, an inflated shape of the inflation portion 18 is regulated by the inflation-time cross-sectional shape regulation component 22 at the time of the side impact, and the inflation portion 18 can be caused to inflate up to a position corresponding with a temple portion 14S of the occupant 14. Thus, inertial force in a vehicle lateral direction of the cephalic region 14H of the occupant 14 can be absorbed by the inflation portion 18.

A rollover determining apparatus and methods for determining whether a vehicle is about to roll over distinguishes a type of rollover that is likely to occur to the vehicle based on the lateral acceleration of the vehicle and the roll angle of the vehicle. Moreover, a determination is made whether the state of the vehicle indicated by a first quantity corresponding to the distinguished type of rollover is in a rollover region determined by a predetermined threshold line. The apparatus and methods can also change the threshold line in accordance with the magnitude of second quantity that is different from the first quantity and that corresponds to the distinguished type of rollover.

In a vehicle front structure 12, when there is a frontal collision of a vehicle, an air bag 32 is inflated and deployed to the outside of a column cover 22, and thereby, the knees of a driver are restrained and protected by the air bag 32. A right side wall 28C and a left side wall 28D of a second lower column cover 28 are opened by the air bag 32 inflating and deploying. Consequently, the air bag 32 can be inflated and deployed with certainty to the vehicle right and left sides of the column cover 22.

摘要:
An airbag device for a vehicle includes a gas supply portion, an airbag body, and a low-pressure portion. When a vehicle collision occurs, the gas supply portion injects gas into an airbag body. The airbag body has a single-chamber structure. When the airbag body receives the gas from the gas supply portion, the airbag body is inflated and deployed toward an occupant to restrain the shoulders of the occupant. The low-pressure portion is provided in the same area of the airbag body, which faces the occupant when the airbag body is inflated and deployed, to protect the occupant's head. When the airbag body is inflated and deployed, the low-pressure portion is inflated such that the pressure in the low-pressure portion is lower than the pressure in the airbag body.
