Actuator 28 and stretch sensor 30 can be sandwiched between two stretch fabric layers 32, 34. The number of stretch fabric layers is not limited to two layers. It is understood that the two stretch fabric layers 32, 34 need not be identical. Actuator 28 may be sandwiched between two stretch fabric layers that are different from the two stretch fabric layers that sandwich stretch sensor 30 . Actuator 28 can be sandwiched between two layers of stretch fabric, and stretch sensor 30 can be sandwiched between two layers of stretch fabric, with one stretch fabric layer common to both actuator 28 and sensor 30.

As a non-limiting example, as shown in FIG. 4, some areas 40 of a seat covered with stretchable fabric 12 can include actuators 28 and stretch sensors 30.

The method of interaction between motor vehicle 100 and a user may include various steps.

The information received from the stretch sensor 30 causes the control unit 36 to persistently detect the presence of at least one user 38 on the seat 10, 24, 26 of the motor vehicle 100 by means of the stretch sensor 30 and to persistently define the contact zone. allows determining the contact zone between the user and the seat by mapping the The control unit 36 may be configured to be able to determine the posture of the user.

The control unit 36 then determines the stimulation zone based on the contact zone and determines the stimulation delivered to the user depending on the driving condition. The determination of the stimulation zone and the type of stimulation delivered to the user takes into account the user's morphology and that some parts of the body contain more nerve endings and may therefore be more sensitive to stimulation. , may depend on which part of the user's body is in contact with the seat.

The information sent to actuator 28 enables control unit 36 to deliver stimulation to the user via the stimulation zone.

As a non-limiting example, when control unit 36 determines that the user is not in contact with a portion of area 40 that includes actuator 28 and stretch sensor 30, as shown in FIG. The stimulation zone can be determined taking into account only the area 40 where the stimulation occurs.

As a non-limiting example, as shown in FIG. 13, from the determined stimulation zone, the control unit 36 can determine that the user stimulation should be delivered in the neck/shoulder area 56 of the seat 10.

As a non-limiting example, as shown in FIG. 14, control unit 36 may determine to send user haptic feedback (such as vibrations) in neck/shoulder area 56.

As a non-limiting example, as shown in FIG. 36 may determine to send active vibrations 64 in the lumbar area 58. The vibrations 64 move from one side of the waist area 58 to the other.

As a non-limiting example, as shown in FIG. 16, control unit 36 may determine that one area 60 of the cushion is a stimulation zone and that the stimulation is a deformation of area 60 of cushion 14 illustrated by arrow 66. .

As a non-limiting example, the vibration intensity, frequency and pattern can be based on motion sensing of the motor vehicle 100. As a non-limiting example, control unit 36 may include motion sensing equipment to measure inertia, illustrated by traction circle 42 in FIG.

In FIG. 11, arrows with the letter A represent acceleration, arrows with D represent deceleration, arrows with L represent counterclockwise rotation, and arrows with R represent clockwise rotation.

The traction circle 42 has an area 44 in which no stimulation is delivered to the user, and above a threshold, e.g. an area 46, the control unit 36 determines that the stimulation is not delivered to the user for anticipatory purposes and/or to avoid motion sickness. You can decide to send it to

By way of non-limiting example, as shown in FIGS. 17 and 18, the control unit 36 can control the stimulation zones to be located on the right side 68 of the backrest 16 of the seat 10, on the left side 70 of the backrest 16 of the seat 10, and on the right side of the cushion 14 of the seat 10. 72 and the left side 74 of the cushion 14 of the seat 10.

As non-limiting examples, these stimulation zones may be selected for anticipatory purposes and/or to avoid motion sickness.

Depending on the driving situation, i.e. depending on the traction circle 42 and the contact zone, the control unit 36 controls the right side 68 of the backrest 16 of the seat 10, the left side 70 of the backrest 16 of the seat 10, the right side 72 of the cushion 14 of the seat 10. and one of the left sides 74 of the cushion 14 of the seat 10 should be stimulated.

As a non-limiting example, as shown in FIG. 18, control unit 36 may determine that the vibrations are active vibrations as indicated by arrows 76 and 78. Active vibrations can induce muscle stimulation in the user's body for anticipatory purposes.

As a non-limiting example, if the control unit 36 determines that cornering anticipation is requested, the control unit 36 may cause the vibration to move from the right side 68 of the backrest 16 of the seat 10 to the backrest 16 of the seat 10 as indicated by arrow 78. and/or from the right side 72 of the cushion 14 of the seat 10 to the left side 74 of the cushion 14 of the seat 10.

As a non-limiting example, if the control unit 36 determines that cornering anticipation is requested, the control unit 36 may cause the stimulus to move from the left side 70 of the backrest 16 of the seat 10 to the backrest of the seat 10 as shown by arrow 78. 16 and/or from the left side 74 of the cushion 14 of the seat 10 to the right side 72 of the cushion 14 of the seat 10.

As a non-limiting example, if the control unit 36 determines that a speed change anticipation is requested, the control unit 36 may cause the stimulus to move from the right side 68 of the backrest 16 of the seat 10 to the cushion of the seat 10 as indicated by the arrow 76. 14 and from the left side 70 of the backrest 16 of the seat 10 to the left side 74 of the cushion 14 of the seat 10.

As a non-limiting example, if the control unit 36 determines that a speed change anticipation is requested, the control unit 36 may cause the stimulus to move from the right side 72 of the cushion 14 of the seat 10 to the backrest of the seat 10 as indicated by the arrow 76. 16 and from the left side 74 of the cushion 14 of the seat 10 to the left side 70 of the backrest 16 of the seat 10.

The stimulation can vary depending on the orientation of the seats 10, 24, 26 relative to the motion of the motor vehicle 100. As a non-limiting example, cornering anticipation, acceleration anticipation, and deceleration anticipation are different when the seat is rear-facing, i.e., the user is looking at the rear of the motor vehicle; This is the opposite of cornering anticipation, acceleration anticipation, and deceleration anticipation. As a non-limiting example, when the seat is sideways, i.e. when the user is looking at the side of the motor vehicle, the cornering anticipation is a stimulus according to arrow 76 and the acceleration or deceleration anticipation is a stimulus according to arrow 78 in FIG. It can be used as a stimulus.

Control unit 36 may include safety sensor systems that may include pre-collision systems, motion sensing systems, and/or brake assist systems.

As a non-limiting example, the stimulus may be a deformation of a portion of the seat based on safety sensing of the motor vehicle 100. As a non-limiting example, control unit 36 may include a safety sensor system that measures inertia, as illustrated by traction circle 48 shown in FIG.

In FIG. 12, arrows with the letter A represent acceleration, arrows with D represent deceleration, arrows with L represent counterclockwise rotation, and arrows with R represent clockwise rotation.

The traction circle 48 may have an area 50 in which no stimulation is delivered to the user, and above a threshold, for example in areas 52 or 54, the control unit 36 may have an area 50 in which stimulation is not delivered to the user for safety and to protect the user. Can be determined to be sent to the user. Depending on the driving conditions, ie depending on the traction circle 42 and the contact zone, the control unit 36 can decide that a given stimulation zone is to be stimulated.

As a non-limiting example, the control unit 36 may determine that based on driving conditions, i.e. when extreme deceleration is perceived, the stimulation zone is at the front of the cushion 14 and the stimulation has an anti-submarine effect, i.e. under the user's seat belt. It can be determined that there is an upward deformation of the front part of the cushion 14 so as to enhance the slip-off avoidance. Once this feature is deemed no longer needed, the control unit 36 can stop the stimulation and the seat 10 can return to the initial shape of the cushion 14.

By way of non-limiting example, the control unit 36 may determine that based on the driving conditions, i.e. when extreme cornering is perceived, the stimulation zone is the side support 20 and the stimulation is a deformation of the side support 20 towards the user. , can be determined. The lateral supports can absorb the inertia of the user's body applied to the seat 10 and help maintain body posture. If this feature is deemed no longer necessary, the control unit 36 can stop the stimulation and the seat 10 can return to the initial shape of the side supports 20.

By way of non-limiting example, the control unit 36 may determine that depending on the driving condition, i.e. when a side impact is expected, the stimulation zone is the shoulder and head protection 22 and the stimulation is directed towards the user of the shoulder and head protection 22. It can be determined that it is a deformation. The shoulder and head protector 22 can be deformed to wrap around the user's head and shoulders to prevent neck injury and/or protect the user from debris protrusions when a side impact is detected.
