    Abstract: To provide a vehicle seat safety device capable of preventing distortion of a seat back in the width direction when a vehicle collision occurs, thereby appropriately restraining an occupant. RESOLUTION MEANS
    The present invention relates to a vehicle seat safety device that is provided with a reclining mechanism enabling adjustment of the angle of a seat back and protects an occupant seated in the vehicle seat. The seat belt extends diagonally from an upper end part of a first side in the width direction of the seat back to a lower end of a second side on an opposite side of the first side. A rotation shaft part, which serves as an axis when the seat back is reclined, is provided with an adjustment means for varying the amount of rotation of the first side and the second side of the seat back in the event of a vehicle collision.

    Abstract: PROBLEM
    To provide an airbag device that enables restraining the head of an occupant riding in a passenger seat of a vehicle.
    RESOLUTION
    The present invention is an airbag device that is stowed in the instrument panel of a vehicle in order to protect an occupant in a passenger seat and includes an inflator for generating expansion gas along with an airbag that inflates and deploys toward the occupant side via gas released from the inflator. The airbag is connected to the inflator and includes a main chamber positioned in front of the occupant properly seated during deployment and a sub chamber connected to at least one side of the main chamber. An inner vent through which gas flows, is formed at a boundary portion of the main chamber and the sub chamber. Furthermore, a check valve for opening and closing the inner vent is provided.
