    • A longitudinally adjustable vehicle seat, including a seat cushion and a seatback, is supported on a bi-level seat frame for movement from an occupant in-use position to a compact fold-flat stowed position. The bi-level seat frame includes a front lower portion slidably supported on front track assemblies and a rear elevated portion slidably supported on rear track assemblies. A pair of forward upright links each has a lower end pivoted on the seat frame front portion for rotation about a first transverse axis and upper ends pivoted to associated front underlying portions of the seat cushion for rotation about a second transverse axis. A pair of upstanding laterally spaced arms each has a lower end fixed to an aft end of the seat cushion and an upper end pivoted to an intermediate portion of the seatback for rotation about a third transverse axis. The seatback has its lower portion pivoted to a pair of pivot mounts on the seat frame elevated portion for rotation about a fourth transverse pivot axis. Upon the seatback being unlatched and pivoted forwardly about the pivot mounts, the seat cushion undergoes conjoint parallelogram movement, about the four pivot axes to a stowed position adjacent the floor of the vehicle, wherein the seatback is stowed in an overlying manner relative to the seat cushion. The rear surface of the stowed seatback is disposed flush with the surface of the vehicle elevated rear cargo load floor.
    • 包括座垫和座椅靠背的纵向可调整的车辆座椅被支撑在双层座椅框架上,用于从乘员在使用位置移动到紧凑的折叠平放位置。 双层座椅框架包括可滑动地支撑在前轨道组件上的前下部分和可滑动地支撑在后轨道组件上的后升高部分。 一对前直立连杆各自具有枢转在座椅框架前部上的下端,用于围绕第一横向轴线旋转,上端枢转到座垫的相关联的前部下部,以绕第二横向轴线旋转。 一对直立的横向间隔的臂各自具有固定到座垫的后端的下端,并且上端枢转到座椅靠背的中间部分,以绕第三横向轴线旋转。 座椅靠背具有其下部枢转到座椅框架提升部分上的一对枢转安装件,用于围绕第四横向枢转轴线旋转。 当座椅靠背解锁并绕枢轴安装座向前枢转时,座垫经历围绕四个枢转轴线的相互平行四边形移动到靠近车辆地板的收起位置,其中座椅靠背以相对于座椅的上方方式收起 坐垫。 收起的座椅靠背的后表面与车辆升高的后货物地板的表面齐平地设置。
