Seat module and transportation device

A transportation device comprising:

• a frame;
• and
• a seat module comprising a seat body, a calf rest and an operating member, the seat body being pivotally connected to the frame, the seat body having a first engaging portion, the calf rest being pivotally connected to the seat body at a first pivotal portion, the operating member having a press portion, an elastic portion, a second pivotal portion and a second engaging portion, the operating member being pivotally connected to the calf rest by the second pivotal portion, the elastic portion abutting against the calf rest;
• wherein
• the second engaging portion engages with the first engaging portion and the calf rest, such that the calf rest is kept at a predetermined position,
• responsive to the press portion being pressed, the elastic portion is compressed to deform elastically and the second engaging portion disengages from the first engaging portion, such that the calf rest is able to rotate with respect to the seat body to adjust an angle of the calf rest,
• responsive to the press portion being released, the elastic portion returns the operating member, and
• the second pivotal portion is between the first pivotal portion and the elastic portion.
