Abstract: This locking device for an electromechanical actuator comprises a rod that is movable relative to a cylinder under the action of a motor actuating the rod, an assembly of at least one hook that can be moved between a locked position in which said hooks engage in an indentation and an unlocked position in which said set of hooks is released from the indentation, one of said set of hooks and the indentation being provided on the cylinder and the other on the rod. It comprises a sliding lock that can slide relative to said hooks and to the indentation between a holding position in which said hooks are held in the locked position a released position in which said hooks are released under the action of the motor actuating the rod.

Abstract: The present invention relates to an electromagnetic assembly of polyphase structure, said assembly including: a yoke comprising an electromagnetic body; a plurality of spaced-apart blocks that protrude with respect to one of the carrier faces of the yoke and that are arranged, consecutively, along the periphery of the carrier face of the yoke; and at least one winding that is associated with the blocks, wherein there is only one yoke, the plurality of blocks is arranged in at least two groups of blocks (A, B, C) in which two consecutive blocks of a given group of blocks (A, B, C) are spaced apart by an inter-block distance (E), and each group of blocks (A, B, C) is separated from the adjacent group of blocks (A, B, C) by an inter-group distance (D) that is different from the inter-block distance (E).

Abstract: This actuator comprises a frame, a motor, an output shaft, and a drive train for driving the output shaft via the motor. The drive train comprises an upstream element, a downstream element, and a device for coupling the upstream element to the downstream element. Said coupling device has a first configuration for transmitting all of the torque exerted by one of the upstream and downstream elements on the coupling device to the other of the upstream and downstream elements when said torque is below a threshold torque, and a second configuration for diverting at least part of said torque exerted by one of the upstream and downstream elements on the coupling device to the frame when said torque is at least equal to the threshold torque.

Abstract: A control device for the comfort equipment of a passenger transport vehicle seat module includes a casing having a control unit and an USB port, a transmitter/receiver having an electrical plug to be plugged into the USB port, the transmitter/receiver to receive an adjusting command and to transmit the received adjusting command to the control unit, the control unit to transmit the received adjusting command to the one piece of comfort equipment. The control device further includes a locking device having a maneuvering member. When the maneuvering member is actuated, the locking device prevents the transmission of the adjusting command from the transmitter/receiver to the piece of comfort equipment.

Abstract: Disclosed is a seat intended in particular for a passenger transport vehicle, the seat including a seating part, a backrest that pivots relative to the seating part, a headrest, and an active noise control device including: at least one error sensor capable of sensing a minimization acoustic field and generating a reference signal; a reference sensor able to capture an undesirable acoustic field; a processing unit able to generate a cancellation signal from the reference signal and from a signal representative of the undesirable acoustic field; and at least one speaker able to emit a cancellation acoustic field from the cancellation signal. The headrest includes a support and a first deformable casing carried by the support. The at least one error sensor is arranged on the first deformable casing.

Abstract: A vehicle seat is provided including at least first and second movable seat elements relatively to each other and at least one actuator ensuring a relative movement between both elements. The actuator includes a sensor for measuring a piece of representative information of the position of a first seat element relatively to a second seat element. The sensor includes an inclinometer secured to the first seat element. The piece of representative information of the position of the first seat element is an inclination of the first seat element.

Abstract: The present invention relates to equipment (80, 80A, 80B, 80C, 80D, 80E) for an airplane seat (36A) having at least two states comprising a first antenna (150A) able to transmit a state signal (158A) relative to the state of the equipment (80, 80A, 80B, 80C, 80D, 80E) and a second antenna (154A) able to receive a control signal (182) to change the state of the equipment (80A).
