  • Patent number: 9630539
    Abstract: A tiltable vehicle seat has a seat frame, a pad formed in a mold associated with the seat frame and a bracket attaching a seatback to the seat frame. The pad is formed through foaming to expand and engulf the seat frame and is integrated with the seat frame. The bracket allows for the seat frame and the pad contained therein to be tilted relative to the seatback to provide multiple vehicle seat modes. The bracket is formed separately from the seat frame and attached to the seat frame thus allowing for the pad to be formed from a relatively compact mold.

  • Patent number: 8123272
    Abstract: A vehicle seat is taught that preferably include a seat cushion (10), a seat back (20) rotatably connected to the seat cushion via a reclining mechanism (30), front (40) and rear (46) legs removably connecting the seat cushion to a vehicle floor (66), a retracting link (50), an operating member capable of removing the front and rear legs from the floor, and a coupling link (54). The seat back can be rotated forwardly by unlocking the reclining mechanism, so as to be superimposed on the seat cushion. When the front and rear legs are removed from the floor, the seat can be moved from a use condition to a retracted condition depending on the motion of the retracting link. When the seat is moved from the use condition to the retracted condition, the coupling link rotates the front leg based on a displacement of the retracting link, thereby unlocking the reclining mechanism.

  • Patent number: 8038206
    Abstract: An operating lever is provided at one of a front face, an upper face, and a back face of a seat including a seat cushion and a seat back. The operating lever may include a first lever having a first end and a second end, and a second lever having a first end and a second end. The second end of the first lever and the first end of the second lever may be pivotably connected to each other, and the first end of the first lever may be pivotably connected to the seat such that the first lever is configured to change an attitude of the seat. In addition, the second end of the second lever may be formed as an operating portion, and when the operating portion is operated in a direction away from the seat, the first lever and the second lever pivot may away from the seat and the attitude of the seat is adjusted.

  • Publication number: 20100207417
    Abstract: One aspect of the present invention can include an operating lever of a vehicular seat provided at a front face, an upper face, or a back face of a seat, including a seat cushion and a seat back, and a first lever and a second lever. The first lever and the second lever are axially supported pivotably to each other on one end sides in length directions. An other end side in the length direction of the first lever is axially supported pivotably to the seat and is connected to a lock mechanism capable of changing a state of an attitude of the seat. The other end side in the length direction of the second lever is formed as an operating portion. The attitude of the seat can be operated while bending the first lever in two stages around axial shafts on sides of both ends in the length direction of the first lever by operating an operating portion of the second lever in a direction of being remote from the seat.

  • Publication number: 20080169668
    Abstract: A vehicle trunk internal storage compartment structure including a floor portion formed with a storage recess open toward the vehicle top; a lid body covering the storage recess opening; and a link member connecting the lid body with the storage recess inside. First and second end portions of the link member are connected to the lid body and the storage recess inside, respectively, so as to be relatively rotatably and relatively moveable with respect thereto. A first end portion guide member is provided to the lid body enabling guiding of the first end portion of the link member in a direction orthogonal to the link member relative rotation axis with respect to the lid body. When stowing the vehicle seat, a coupling mechanism couples the lid body to the movement of the vehicle seat and opens the lid body by the seat stowing operation alone.
