Abstract: A sun protection apparatus includes a shading device, including an upper bar, a lower bar and a screen disposed between the upper and lower bars. The apparatus also includes a motorized drive device, designed to deploy and fold away the screen, including a first electromechanical actuator, configured to move the upper bar, a second electromechanical actuator, configured to move the lower bar, and a control unit, configured to control the first and second actuators. The control unit controls the first actuator so as to move the upper bar then the second actuator so as to move the lower bar depending on the position and/or movement of the upper bar, or vice versa.

Abstract: A method for detecting an obstacle opposing the movement of a screen in a home automation closure or sun protection system includes an electromechanical actuator driving movement of the screen. The electromechanical actuator includes a torque support, a housing, an output shaft, and an electric motor including a stator and a rotor. The system includes a winding shaft rotating the screen and a connecting accessory between the electromechanical actuator's output shaft and the winding shaft. The method includes: determining an angular displacement value of the rotor with respect to the stator; determining angular displacement of the winding shaft relative to the housing or torque support of the electromechanical actuator; determining angular deformation of the kinematic chain between the electric motor and the winding shaft by comparing these two angular displacements; and determining the presence of an obstacle to screen movement from an angular deformation exceeding a predefined value.

Abstract: A screening device includes a rail, a drive shaft, a motorized drive device, including an electromechanical actuator, and an autonomous electrical power supply device, including a battery module. The battery module includes first and second mounting brackets, each arranged inside the rail and configured to hold the battery module inside the rail. The actuator includes third and fourth mounting brackets, each arranged inside the rail and configured to hold the actuator inside the rail. The brackets are identical. Furthermore, each of the brackets includes an opening, configured to accommodate the drive shaft.
