System for controlling movements of doors of a heating ventilation and air-conditioning module

A system for controlling movements of doors of a heating, ventilation and air-conditioning module, the system comprising:

• an actuation gear;
• a main door comprising a first portion and a second portion having a first guide, wherein the first portion is configured to engage with the actuation gear to enable linear movement of the main door between a first position and a second position;
• a slave door comprising a second engagement element and configured to angularly move between a blocking position and an unblocking position based on movement of the main door;
• and
• an intermediate cam configured to angularly move, comprising a first engagement element and a second guide configured thereon, the intermediate cam being directly connected to the main door and the slave door,
• wherein the first engagement element is configured to interact with the first guide, and the second guide is configured to interact with the second engagement element to facilitate angular movement of the slave door in response to movement of the main door,
• wherein the first guide is configured with a bend so positioned to enable angular movement of the slave door after the main door has moved a pre-determined, non-zero, distance.
