Leg support collapse mechanism for seat and reset method thereof

The invention discloses a leg support collapse mechanism for a seat and a reset method thereof. The mechanism comprises a fixing bracket provided with a fixing slider; A sliding groove for relative sliding of the fixed slider is arranged on the motor bracket; A first locking piece rotatably connected to the first side of the chute; A second locking piece rotatably connected to the second side of the chute; The first direction pressure and the second direction pressure are a pair of equilibrium forces before the motor support reaches the failure load; The first directional pressure and the second directional pressure generate a pressure difference after the motor support reaches a failure load to release the relative fixation of the fixed slider and the sliding groove. The first directionalpressure and the second directional pressure generate a pressure difference after the motor support reaches a failure load to release the relative fixation of the fixed slider and the sliding groove.By providing a sliding gr
