Abstract: A seat angle adjustment device includes a ratchet wheel, a stop plate, a locking slipper and a pawl, wherein a first stop position limiting part and a second stop position limiting part are arranged on the stop plate, when the first stop position limiting part is subjected to a rotating torque in a rotational direction, the locking slipper in a locking position circumferentially abuts against the first stop position limiting part; when the rotating torque is higher than a first preset torque value, the pawl in an extended state is driven by the ratchet wheel to rotate until the tooth part on one side of the pawl is completely engaged with the ratchet wheel; and when the rotating torque is higher than a second preset torque value, the second stop position limiting part abuts against the pawl. A seat having the seat angle adjustment device is also provided.
