Each symmetric foldable seat mounting supports comprises: an upper mounting base (110), a lower mounting base (120), a pinion (140), a locking lever (170), a main connecting plate (130), a first and a second auxiliary connecting plates (150,160). The main connecting plate (130) is pivoted on both upper and lower mounting bases (110,120). The pinion (140) is pivoted at a middle portion on an inner side of the main connecting plate (130). Side surfaces at one end of both auxiliary connecting plates (150,160) are formed with racks engaging with the pinion (140). The first auxiliary connecting plate (150) is pivoted on the lower mounting base (120) and the second auxiliary connecting plate (160) is pivoted on the upper mounting base (110). One end of the locking lever (170) is pivoted on the upper end of the main connecting plate (130), and the other end presses against the pinion (140).
