摘要： A partition provided between a pair of vehicle seats arranged to face each other in a vehicle cabin is provided to extend from an upper part to a lower part of the vehicle cabin in a partitioning state. Therefore, the partition in the partitioning state can block respective visual lines of occupants seated in the pair of vehicle seats. Since the partition in the non-partitioning state is accommodated in a predetermined position, by setting the partition to the non-partitioning state when the occupant is seated on only one side of the pair of vehicle seats or the like, the occupant can obtain a feeling of openness. The partition can be selectively switched between the partitioning state and the non-partitioning state by an operation switch. Accordingly, it is possible to secure a private space for allowing the occupant to have a comfortable state or a relaxed state inside the vehicle cabin.

摘要： A vehicle side structure includes a window, which has a window opening defined in a side wall of a vehicle and a window glass for covering the window opening, a curtain air bag device attached to a position above the window, and a bar-shaped member configured to partition the window opening into upper and lower sections when viewed along a lateral direction of the vehicle. In the vehicle side structure, the bar-shaped member is placed inside the window opening or at a position located, in a vehicle width direction, on an inner side of the window opening and also on an outer side of a fully inflated curtain air bag, and at least a part of the fully inflated curtain air bag expands to a region below the bar-shaped member.

摘要： In a vehicle seat system, lowering of a seat cushion further toward a vehicle lower side than a lowerable limit value corresponding to a recline angle of a seatback is restricted by a control device in cases in which the physical build of an occupant is smaller than a predetermined value. This enables a reduction in the ability to restrain the body of the occupant using a webbing to be suppressed.

摘要： A vehicle occupant protection device includes a seat belt device having a variable force limiter mechanism that can change a force limiter load that an occupant who is sitting on a vehicle seat receives from a seat belt at a time of a frontal collision of a vehicle, an airbag device that deploys an airbag toward the front of the occupant at the time of the frontal collision, a seating position detection unit that detects a seating position at which the occupant is seated, and a control unit that reduces the force limiter load if, compared to a case in which the occupant is positioned within a standard seating region, the seating position of the occupant detected by the seating position detection unit is further toward a vehicle rear than the standard seating region and is within an airbag protection region in which the occupant is protected by the airbag.
