A riser assembly extends between a seat cushion and a floor of an automotive vehicle. The riser assembly includes a floor bracket that is fixedly secured to the floor. A rod extends laterally within the vehicle and is fixedly secured to the floor bracket. A front leg extends between upper and lower ends. The upper end is pivotally coupled to the seat cushion for movement of the seat cushion between a generally horizontal seating position and an upright position. The lower end is slidably coupled to the rod for lateral sliding movement of the seat cushion between primary and secondary positions. A pulley wheel is pivotally coupled to the front leg between the upper and lower ends. A cable includes an intermediate portion that extends between a first end fixedly secured to the seat cushion and a second end fixedly secured to the floor bracket. The intermediate portion is wrapped around the pulley wheel for effecting automatic lateral movement of the seat cushion between said primary and secondary positions in response to pivotal movement of the seat cushion between seating and upright positions, respectively. A biasing member extends between the front leg and the floor bracket for laterally biasing the seat cushion toward the primary position. |
