Figure 1 shows an example of a seat module 2 according to the invention. Such a seat module 2 may for example be installed in a passenger transport vehicle. Typically, such a seat transport module may be installed in a first class or business class area of a passenger transport aircraft.
This seat module 2 comprises a seat 4, a shell 6, comfort equipment 8 and a control device 10 capable of controlling this comfort equipment.
The seat 4 comprises a seat bottom 12, a seat back 14, a head rest 16 and a leg rest 18.
In the example shown, the shell 6 surrounds the back and the sides of the seat 4. It is prolonged at the side of the seat by a vertical wall 20 truncated at mid-height to for a work table 22.
In the example shown on figure 2, the comfort equipment 8 comprises a seat bottom height actuator 24, a seat bottom depth actuator 26, a seat back pivot actuator 28 and a leg rest pivot actuator 30 formed in the shell 6.
The seat bottom height actuator 24 is capable of moving the seat bottom vertically to modify its height H. The seat bottom depth actuator 26 is capable of moving the seat bottom horizontally, in the front-back direction, to modify the depth P of the seat bottom.
The seat back pivot actuator 28 is adapted to pivot the seat back 14 relative to the seat bottom 12 by an angle a about an axis extending along the y direction relative to the orthogonal coordinate system (x, y, z) represented on figure 1. The leg rest pivot actuator 30 can pivot the leg rest 18 about an axis extending along the y direction.
The comfort equipment 8 also comprises a lighting device 32, loud speakers 34 and loud speaker movement actuators 36.
In the example shown, the lighting device 32 comprises three light sources that may for example be composed of light emitting diodes. Preferably, these light emitting diodes have an adjustable light intensity. The lighting device 32 is formed on the vertical wall 20 of the shell 6 at a height corresponding to the height of the head rest 16.
The loud speakers 34 are mounted on the walls of the shell 6 extending on each side of the head rest 16.
In the example embodiment illustrated on figure 1, the loud speakers 34 are mounted on vertical slides 38 and the loud speaker movement actuators 36 are capable of moving them vertically.
According to one variant not shown, the loud speakers 34 are mounted on horizontal slides and the loud speaker movement actuators 36 are capable of moving them horizontally to move them closer to or further away from the head rest 16.
According to another variant not shown, the loud speakers 34 are arranged to pivot about an axis extending along the y direction, parallel to the seat back pivot axis.
For example, the loud speakers 34 form part of an active noise control device 40. In this case, a microphone is positioned close to each loud speaker. These microphones are then also moved by movement actuators 36.
The loud speakers 34 can also be used to broadcast musical or voice recordings related to a displayed video or to transmit announcements broadcast by the airline.
The control device 10 for this comfort equipment is shown diagrammatically on figure 2. It comprises a tablet 41 or a remote control for the manual commands for comfort equipment 8; a first imager 42; a second imager 44 and a control unit 46 communicating with the first imager 42 and the second imager 44; for example through wire communication links.
The tablet 41 or the remote control are capable of receiving adjustment commands generated by the passenger for comfort devices 8. These adjustment commands include, for example; commands to raise the seat bottom, pivot the seat back 14 or the leg rest 18.
The images 42, 44 are for example, composed of a camera or cyber camera (webcam).
In the example embodiment represented on figure 1, the first imager 42 is arranged in the shell 6 on a part of the vertical wall 20 that extends to the height of the head rest. It is capable of acquiring at least one image representing the upper part of the passenger's body. In particular, the first imager 42 is capable of imaging the passenger's thighs and face and more particularly his or her eyes and eyelids.
Preferably, the light sources 32 and the imagers 42 and 44 are flush with the surface of the vertical wall. Advantageously, this arrangement is aesthetic.
The second imager 44 is arranged in the shell 6 on a part of the vertical wall that extends to the height of the leg rest 18. It is capable of acquiring at least one image representing the lower part of the passenger's body. In particular, the second imager 44 is capable of imaging the passenger's legs.
As a variant, the control device 10 comprises a single imager capable of imaging the passenger as a whole.
As a variant, the control device 10 comprises more than two imagers.
With reference to figure 2, the control unit 46 comprises a memory 48 and a calculation unit 50 connected to the memory 48. For example, it consists of a processor.
The memory 48 includes instructions to execute the command process according to the invention and predetermined parameters.
The predetermined parameters are parameters used by the control unit to determine the length of some parts of the body, starting from the acquired image.
For example, these parameters include predefined average length measurements between each imager and parts of the body that the control unit is required to detect or measurements of the length of seat elements that are also displayed on the images. These length measurements are used to determine the length of some parts of the body starting from the acquired image and applying a proportionality calculation.
The control unit 46 is capable of receiving images acquired by the first imager 42 and the second imager 44.
The control unit 46 is capable of applying a segmentation and contour detection type image processing to detect an object representative of at least part of the passenger's body in the image. The control unit 46 is capable of generating at least one adjustment command to be sent to a piece of comfort equipment 8 as a function of said detected part of the passenger's body.
Thus, the control unit 46 may for example be capable of detecting an object in the image representative of at least one of the passenger's legs and determining the length of this leg from predetermined parameters. The control unit 46 is then capable of generating at least one seat bottom height H adjustment command as a function of the determined length and transmitting this command to the seat bottom height actuator 24.
The control unit 46 is capable of detecting an object in the image representative of a passenger's thigh and determining the length of this thigh from predetermined parameters. The control unit 46 is capable of generating a seat bottom depth P adjustment command as a function of the determined thigh length and transmitting this command to the seat bottom depth actuator 26.
The control unit 46 is capable of locating the position of at least one of the ears of a passenger sitting on the seat by detection of an object in the image representative of the passenger's ear. The control unit 46 is capable of generating a loud speaker movement command as a function of the determined ear location and transmitting this command to the loud speaker movement actuator 36.
The control unit 46 is capable of detecting an object in the image representative of at least one closed eyelid of the passenger sitting on the seat. The control unit is capable of generating a command to pivot the seat back when the passenger's eyelid is closed, and sending it to the seat back pivot actuator 28.
When the passenger's eyelid is closed, the control unit 46 can also generate a command to pivot the leg rest and transmit this command to the leg rest pivot actuator 30.
Finally, when the passenger's eyelid is closed, the control unit can also generate a command to dim the lighting or a command to switch the lighting device off and send this command to the lighting device 32.
The calculation unit 50 is capable of executing the instructions in the command process recorded in the memory.
With reference to figure 3, the command process according to this invention begins with a step 52 for the acquisition of one or several image(s) representing a passenger resting on the seat.
During a step 54, the control unit 46 detects an object in the image representative of at least one part of the passenger's body.
During a step 56, the control unit 46 determines the bodily characteristics of the passenger from the detected object. These bodily characteristics are for example the length of a thigh or the presence of a closed eyelid.
During a step 58, the control unit 46 generates a command to adjust a piece of comfort equipment as a function of the determined bodily characteristics and predetermined parameters.
During a step 60, the control unit controls a timeout. The control unit 46 does this after waiting for a predetermined duration before sending the command generated during step 58.
During a step 62, the piece of comfort equipment 8 receives the command sent by the command unit. This command actuates the control equipment or puts it into operation.
Advantageously, the timeout makes the command smoother, without surprising the passenger.
According to one advantageous embodiment, the seat module comprises a retractable table used particularly to support meal trays. This table is free to move between a position in which it is housed in a housing of the vertical wall 20 and a position in which it is extracted from this housing. The first imager 42 is capable of imaging this table when it is in an extended position. The control unit 46 is capable of detecting the presence of the retractable table at the passenger's thighs by processing of the image acquired by the first imager. When the extracted position of the retractable table is detected, the control unit is capable of blocking displacement of the seat bottom 12 towards the table to avoid trapping the passenger's thighs.
According to one advantageous variant, the first imager 42 is capable of imaging the head rest 16. The control unit 46 is capable of detecting the position of the head rest 16 by processing of the image acquired by the first imager 42. The control unit 46 is capable of moving one of the loud speakers 34 and/or the active noise control device 40 as a function of the position of the head rest. In particular, the loud speaker(s) 34 and/or the active noise control device 40 are moved so that they are positioned at a height corresponding to the mid-height of the head rest.
