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.

Actuator and cabin seat comprising such an actuator

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.

Seat particularly for a passenger transport vehicle

The present invention relates to a lighting device for lighting the cabin of a motor vehicle, the device comprising an elongate light source disposed inside a housing. According to the invention, the lighting device further comprises: two windows transparent to the light flux emitted by the source, the windows being spaced apart from each other and comprising a top window through which light radiation is emitted in a generally horizontal direction, and a bottom window through which light radiation is emitted generally downwards; a first directional light reflector disposed between two respective first edges of the windows; and a second directional light reflector disposed between the two respective other edges of the windows; the directional light reflectors having shapes that combine to guide the light flux emitted by the source towards the transparent windows.
