Abstract
A passenger sitting in a car expends continuous effort to stabilize the knees and feet. To alleviate that instability, a leg side support that is useful for various statures and footwear is proposed. Low walls for supporting the leg sides are installed on the seat front floor in the following conditions: they are 74 mm high, 776 – 962 mm from the seat hinge point, with distance of separating walls of 145 (near end) – 169 (far end) mm. The walls can be flattened to accommodate a tall person and passengers' entry and exit from the car. The seat has a concave front part. The 491-mm-long seat sides support the thighs of a passenger sitting with legs apart. The middle part is 439 mm long to prevent pressing the thighs of a passenger sitting with legs together. The seat gradually bows upward, with higher sides that deter passengers from sitting with thighs widened. The proposed design allows passengers of 5 – 95 percentile of women's height (wearing high heels of up to 60 mm) to maintain a sitting posture with extended legs.
