Each screen (1) of a group of screens is configured by a method in which a function is approximated, the function giving the instantaneous axial position (H(t)) of the load bar (2) thereof along an axis (Z) of translation in the form of a function having, as a variable, the instantaneous angular position (y(t)) of a winding device (4). The load bars of the screens are sequentially moved into a plurality of positions in which the load bars are aligned, and then the angular position (y(t)) of the winding device is determined. Next, the coefficients defining the approximation function of each screen are determined. The movement of the load bar of each screen is controlled by an instantaneous angular-position set value (θ(t)), which is in turn predetermined from a representative profile using the one-to-one approximation function.

This electric actuator for driving a home-automation screen is provided with a spring brake (105) comprising a helical spring (130), a friction part (140) having a friction surface (141) against which the helical spring (130) bears radially. Said brake further comprises an inlet part (110) suitable for driving the spring in rotation in a direction reducing the contact force between the spring (130) and the friction part (140), and an outlet part (120) connected to the screen.While the screen is being lowered, the inlet part (110; 210) drives the spring (130; 230) in rotation with the contact force being decreased to the extent that the outlet part (120; 220) is released in rotation, without direct contact between the inlet part and the outlet part. The inlet part (110; 210) has at least two contact surfaces (113a, 113d; 213b, 217c) suitable for transmitting drive torque (CM) for raising the screen (2), by direct contact, to at least two corresponding contact surfaces (123a, 123d; 223b, 227a) of the outlet part (120; 220).

A screen (1) includes a load bar (2), a flexible element (3) supporting the load bar, and a controlled member (4) for winding the flexible member, wherein the member is controlled according to a method that includes controlling the angular movement of the winding member (4) with a temporal set value (θ(t)) of the instantaneous angular position of the winding member, the temporal set value being predetermined from a profile representative of the desired instantaneous axial position for the load bar upon a movement between the first and second positions, using a polynomial function of a degree higher than or equal to 2, which approximates the relation between a value of the instantaneous axial position (H(t)) of the load bar and an instantaneous angular position (γ(t)) of the winding member (4).

This driving carriage for a sliding curtain comprises a body that can move along a rail by virtue of two pairs of carrier wheels supported by the carriage, this body being provided, between the two pairs of carrier wheels along the longitudinal axis of the carriage, with at least one opening designed to receive a part of an inner curved edge of the rail without the rail striking the carriage. This eliminates or greatly limits the risks of the carriage becoming jammed along the rail.
