  • Patent number: 7040685
    Abstract: A third row seat of a vehicle includes a seat back which can be folded down onto a seat cushion, and a headrest which can be pivoted rearward with respect to the seat back. The seat cushion is mounted on the vehicle floor so as to be pivotable rearward. A recess is formed in the floor of the vehicle behind the third row seat. The recess stores the third row seat, with the seat back being folded down, the headrest being pivoted rearward, and the third row seat being pivoted rearward. The headrest is located within a path of the pivotal motion of the seat back and the seat cushion, without increasing the path of the pivotal motion.

  • Patent number: 6698795
    Abstract: A seat belt system for a vehicle, for restraining an occupant in a seat disposed in a compartment of the vehicle. The vehicle comprises an opening formed on at least one side of the vehicular body, and a first door moving between a first state where the first door closes at least a part of the opening and a second state where the first door opens the opening. The seat belt system includes a belt webbing, a retractor disposed in the first door for retracting the proximal end of the belt webbing, and a sliding device fixed on a lower edge of the opening, to which the distal end of the belt webbing is attached. The sliding device permits the distal end of the belt webbing to slide along the lower edge of the opening between a forward position and a rearward position. The distal end of the belt webbing is located at the rearward position when the first door is in the second state.

  • Patent number: 4956943
    Abstract: A side door assembly in an automobile body structure for selectively opening and closing an access opening includes a generally rectangular double-walled door panel structure having a windowpane chamber and a windowpane slot both defined therein. A windowpane is supported for movement between elevated and lowered positions through the windowpane slot such that the windowpane in the lowered position can be substantially concealed within the windowpane chamber. The side door assembly also comprises a window sash mounted on the door panel structure so as to extend above the windowpane slot. This window sash has a front sash portion, a generally horizontally extending sash portion continued from the front sash portion and a generally upright rear sash portion continued from the horizontally extending sash portion. There is also provided a bezel mounted on the door panel structure at a location rearwardly of the upright sash portion and at a level above the waist level of an individual.
