  • VEHICLE SEAT SYSTEM
    Publication number: 20200101874
    Abstract: 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.
