PASSIVE COLLAPSE MOUNTING STRUCTURE FOR SHOULDER MASSAGE MODULE

A passive collapse mounting structure for a shoulder massage module may have a seat back and a shoulder support rotatably mounted at a shoulder position of the seat back. An elastic element may be provided between the shoulder support and the seat back. The elastic element may apply a thrust to flip the shoulder support forward relative to the seat back. A driving mechanism may be provided between the shoulder support and the seat back. The driving mechanism may be configured to actively control the shoulder support to rotate and fold backward against the resistance of the elastic element. When the shoulder support is in a forward-unfolded state, a thrust from an occupant's shoulder may be able to force the shoulder support to passively rotate and fold backward against the resistance of the elastic element.
