  • Publication number: 20110095575
    Abstract: A roof member comprises a front roof and a rear roof which are connected to each other, at least one of which is made of a board-shaped hard roof member. A grip (i.e., an operational member) to be gripped by a passenger is provided at a specified position of the front roof so as to transmit an opening-operational force or closing-operation force by the passenger to the roof member. A guide shaft (i.e., a moving mechanism) is provided to position the grip such that the grip is movable relatively to the roof member. Accordingly, a movable roof structure of a vehicle which can properly improve the operation and handling and decrease the operational force with a simple and light mechanism can be provided.

  • Patent number: 7931332
    Abstract: Disclosed is a rear-seat occupant protection apparatus, which is designed to protect, during a frontal collision of a vehicle, a rear-seat occupant (B) seated in a rear seat (5) located behind a front seat (3) equipped with a seat belt (7) having a load limiter function. The rear-seat occupant protection apparatus comprises a collision detection device (25) adapted to detect the frontal collision of the vehicle, and a seat-back displacing mechanism adapted, when the frontal collision of the vehicle is detected by the collision detection device, to permit a seat back (12) of the front seat (3) to be displaced frontwardly at a given timing consecutive with a frontward displacement of a front-seat occupant (A) seated in the front seat (3). The rear-seat occupant protection apparatus of the present invention can adequately protect a head of the rear-seat occupant during the frontal collision of the vehicle.
