[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0027] To address the technical problem that existing car seats cannot achieve dynamic rocking and thus cannot meet the diverse needs of drivers and passengers, this application provides a seat, a seat control method, an electronic device, and a vehicle that enables the seat to gently rock back and forth dynamically, effectively improving the comfort of drivers and passengers and fully adapting to various scenarios such as resting, relaxing, and aiding sleep in the car.

[0028] In a first aspect, embodiments of this application provide a seat disposed in a vehicle, comprising: Base 100; A seat body 200 is disposed on the base 100. The seat body 200 is rotatably connected to the base 100. The seat body 200 can rotate around the first axis 210. The seat body 200 is provided with a sliding groove 240. The swing mechanism 300 includes: The driving component 310 is fixedly connected to the base 100; The drive link 320 has a first end and a second end. The first end is connected to the output end of the drive member 310 so that the second end rotates around the second axis 330 under the action of the drive member 310. The second axis 330 is parallel to the first axis 210, and the second end is slidably engaged with the sliding groove 240.

[0029] In the embodiments disclosed in this application, the front-to-back direction of the vehicle body is taken as the first direction, the left-to-right direction of the vehicle body is taken as the second direction, and the height orientation of the vehicle body is taken as the third direction.

[0030] like Figures 1 to 3As shown in the embodiments disclosed in this application, the seat is a single seat used inside a vehicle. The seat includes a base 100, a seat body 200, and a rocking mechanism 300. The base 100 serves as the mounting and support base for the seat body 200 and is fixedly installed on the vehicle floor inside the vehicle. The seat body 200 is entirely mounted on the base 100. The seat body 200 and the base 100 are rotatably connected. Specifically, a first shaft 210 is provided between the seat body 200 and the base 100. The first shaft 210 extends along a second direction, allowing the seat body 200 to rotate around the first shaft 210. The seat body 200 also has a sliding groove 240.

[0031] The rocking mechanism 300 drives the seat body 200 to rotate around the first axis 210. It is positioned between the base 100 and the seat body 200. The rocking mechanism 300 includes a drive component 310 and a drive link 320. In the embodiments disclosed in this application, the drive component 310 is a motor, which is fixedly mounted on the base 100 to ensure the stability of the driving force output. For example, a Hall effect brushless motor can be used. Hall effect brushless motors have the characteristics of real-time position detection and high-precision power output. They can detect and record the real-time position information of the drive link 320. Combined with the mechanical transmission relationship, the position data information of the drive link 320 can be accurately calculated, effectively improving the accuracy of the seat rocking motion.

[0032] The drive linkage 320 has a first end and a second end. A second shaft 330 is provided between the first end and the output end of the motor. The second shaft 330 is parallel to the first shaft 210, that is, the second shaft 330 also extends along the second direction, and the second end is slidably engaged with the sliding groove 240. In the embodiments disclosed in this application, the second shaft 330 can be a star-shaped linkage. Under the drive of the motor, the drive linkage 320 can rotate around the second shaft 330. At the same time, relying on the sliding engagement relationship between the second end and the sliding groove 240, the rotation of the drive linkage 320 can be converted into linear reciprocating sliding, thereby driving the seat body 200 to complete the rocking motion.

[0033] The specific rocking motion of the seat is as follows: After receiving the start command, the motor continuously outputs power, driving the drive linkage 320 to rotate around the second shaft 330. The second end of the drive linkage 320 is limited by the sliding groove 240, converting the rotation of the drive linkage 320 into reciprocating sliding along the extension direction of the sliding groove 240. When the drive linkage 320 reciprocates, it generates periodic pushing and pulling forces on the seat body 200. Since the seat body 200 is rotatably connected to the base 100 through the first shaft 210, the first shaft 210 becomes the rotation fulcrum of the seat body 200. The seat body 200 reciprocates around this rotation fulcrum in a regular manner, thus realizing the overall rocking motion of the seat. When the motor receives the stop command, its output stops outputting power, the drive linkage stops, and no longer exerts force on the seat body 200. The seat body 200 stops rocking and returns to stillness.

[0034] This application, by setting up a rocking mechanism 300, realizes the gentle dynamic reciprocating rocking of the seat, which can effectively improve the riding comfort of drivers and passengers and can fully adapt to various usage scenarios such as resting, relaxing, and aiding sleep in the car.

[0035] In some embodiments, the sliding groove 240 extends in a direction perpendicular to the first axis 210.

[0036] like Figures 1 to 3 As shown, to further optimize the rocking effect of the seat, in the embodiments disclosed in this application, the sliding groove 240 extends in a direction perpendicular to the first axis 210, that is, it extends along the first direction. Specifically, the seat body 200 is arranged along the first direction, the sliding groove 240 is formed at the bottom of the seat body 200 near the rear side, the front end of the seat body 200 is rotatably connected to the base 100 through the first axis 210, and the rocking mechanism 300 is correspondingly arranged in the area near the rear side of the seat body 200.

[0037] By using a front-mounted rotating fulcrum and a rear-mounted rocking mechanism 300, the force distribution on the seat body 200 can be more even, and the rocking process can be more stable and gentle, effectively improving the riding experience of drivers and passengers.

[0038] For example, the sliding groove 240 is an elongated through groove extending along the first direction. The width of the groove is matched with the sliding head of the second section of the drive link 320. This not only ensures the flexibility of the sliding process, but also effectively limits the sliding range of the drive link 320 and improves the transmission accuracy.

[0039] In some embodiments, the seat body 200 includes: A first support 220 and a second support 230 are provided at intervals along a direction parallel to the first axis 210, and the first support 220 and the second support 230 are respectively provided with the sliding groove 240. A first crossbar 250, one end of which is rotatably connected to the first bracket 220, allowing the first crossbar 250 to rotate around a third axis 251; the other end of which is rotatably connected to the second bracket 230, allowing the first crossbar 250 to rotate around a fourth axis 252; wherein the third axis 251 and the fourth axis 252 are parallel and both are perpendicular to the first axis 210; The swing mechanism 300 is provided in two sets. The second end of the driving link 320 of one set of swing mechanism 300 is slidably engaged with the sliding groove 240 on the first bracket 220, and the second end of the driving link 320 of the other set of swing mechanism 300 is slidably engaged with the sliding groove 240 on the second bracket 230.

[0040] like Figures 1 to 3 As shown, the seat body 200 includes a first bracket 220 and a second bracket 230 spaced apart along a first direction, with sliding grooves 240 respectively provided on the first bracket 220 and the second bracket 230. A first crossbar 250 is provided between the first bracket 220 and the second bracket 230, extending along a second direction. One end of the first crossbar 250 is rotatably connected to the first bracket 220. Specifically, a third shaft 251 is provided between one end of the first crossbar 250 and the first bracket 220, extending along the first direction, allowing the first crossbar 250 to rotate around the third shaft 251. The other end of the first crossbar 250 is rotatably connected to the second bracket 230. Specifically, a fourth shaft 252 is provided between the other end of the first crossbar 250 and the second bracket 230, also extending along the first direction.

[0041] Accordingly, two sets of rocking mechanisms 300 are provided. In the embodiments disclosed in this application, the two sets of rocking mechanisms 300 are symmetrically arranged. The second end of the drive connecting rod 320 of one set of rocking mechanisms 300 is slidably engaged with the sliding groove 240 on the first bracket 220, and the second end of the drive connecting rod of the other set of rocking mechanisms 300 is slidably engaged with the sliding groove 240 on the second bracket 230. By using two sets of symmetrically arranged rocking mechanisms 300, this application can achieve synchronous and asynchronous driving of the first bracket 220 and the second bracket 230, while effectively balancing the left and right force states of the seat during the rocking process.

[0042] The symmetrically arranged left and right sets of rocking mechanisms 300 can achieve both synchronous and asynchronous drive modes. In synchronous drive mode, the left and right sets of rocking mechanisms 300 output driving force synchronously, which can achieve completely symmetrical and even distribution of force on the left and right sides of the seat body 200, effectively improving the stability of the seat body 200 during reciprocating rocking and further optimizing the driving experience. In asynchronous drive mode, the left and right sets of rocking mechanisms 300 output driving force asynchronously, causing the left and right sides of the seat body 200 to swing differently, which can realize various postures such as unilateral rocking and lateral fine adjustment of the seat, and can further expand the applicable scenarios of the seat.

[0043] The first crossbar 250, positioned between the first support 220 and the second support 230, forms a bidirectional independent hinge structure via a third shaft 251 and a fourth shaft 252. This allows it to adapt to the asynchronous drive of the two sets of rocking mechanisms 300, enabling independent unilateral rocking of the seat body 200. Specifically, when the seat body 200 is in asynchronous drive mode, each support independently completes the rocking motion. For example, when only the first support 220 rocks, the first crossbar 250 can rotate relative to the second support 230 via the fourth shaft 252. Similarly, when only the second support 230 rocks, the first crossbar 250 can rotate relative to the first support 220 via the third shaft 251. The hinge structure at both ends of the first crossbar 250 allows for independent rocking of the first support 220 and the second support 230 during asynchronous drive, avoiding problems such as motion jamming caused by inconsistent movement postures on both sides.

[0044] Furthermore, in the embodiments disclosed in this application, the seat body 200 further includes a second crossbar 260. The second crossbar 260 extends along a second direction, with one end connected to the first bracket 220 and the other end connected to the second bracket 230. The second crossbar 260 and the first crossbar 250 are corresponding to each other and cooperate to form the frame of the seat body 200. The front-to-back arrangement of the second crossbar 260 and the first crossbar 250 can further enhance the overall structural rigidity and strength of the seat body 200, improve the load-bearing capacity of the seat, and extend the service life of the seat.

[0045] In some embodiments, the base 100 includes two substrates 110, one substrate 110 being rotatably connected to the first support 220 and the other substrate 110 being rotatably connected to the second support 230.

[0046] like Figures 1 to 3As shown in the embodiments disclosed in this application, the base 100 includes two substrates 110, one of which is rotatably connected to the first support 220, and the other substrate 110 is rotatably connected to the second support 230. Specifically, the substrate 110 has an overall L-shaped structure, including an integrally formed horizontal plate 111 and a vertical plate 112. The horizontal plate 111 of the substrate 110 is fitted and fixed to a preset installation position of the base 100, and a stable assembly with the base 100 is achieved by bolt connection. The vertical plate 112 of the base 100 extends vertically upward, and a rotation assembly hole is reserved on the vertical plate 112. Rotation assembly holes are also reserved at the front ends of the first support 220 and the second support 230 at positions corresponding to the vertical plate 112. A hinge shaft passes through the two mating rotation assembly holes to realize the rotational connection between the first support 220 and the substrate 110, and the rotational connection between the second support 230 and the substrate 110.

[0047] This application sets the base plate 110 as an intermediate adapter, so that the first bracket 220 and the second bracket 230 do not need to be directly connected to the base 100. They can be rotated and connected to the base 100 with the help of the base plate 110. This effectively optimizes the assembly structure of the seat body 200 and the base 100, with a higher assembly error tolerance and more convenient disassembly and maintenance.

[0048] The base 100 can be fixed in close contact with the horizontal plate 111 over a large area, providing strong stability and solid rotational support for the rocking motion of the seat body 200. During the reciprocating rocking motion of the seat body 200, the base plate 110 can continuously bear and distribute the dynamic load transmitted by the seat body 200, avoiding stress concentration, effectively reducing the risk of wear and deformation at the hinge points, and effectively extending the overall service life of the seat.

[0049] In some embodiments, the base 100 further includes two linear guide rails 120, each linear guide rail 120 including a track 121 and a slider 122 that cooperate with each other; In this configuration, the slider 122 of one linear guide rail 120 is connected to one substrate 110 and the drive member 310 of the set of swing mechanisms 300, and the slider 122 of the other linear guide rail 120 is connected to the other substrate 110 and the drive member 310 of the other set of swing mechanisms 300.

[0050] like Figures 1 to 3 As shown, in the embodiments disclosed in this application, the base 100 further includes two linear guide rails 120, which are spaced apart along a second direction. Each linear guide rail 120 includes a track 121 and a slider 122 that cooperate with each other. The track 121 extends along a first direction, and the slider 122 can slide along the extension direction of the track 121.

[0051] The slider 122 of one linear guide rail 120 is connected to a substrate 110 and a drive member 310 of a set of swing mechanisms 300. The slider 122 of the other linear guide rail 120 is connected to another substrate 110 and a drive member 310 of another set of swing mechanisms. That is, each set of swing mechanisms 300 and its cooperating substrate 110 are assembled together on the slider 122 of the corresponding linear guide rail 120. The slider 122 can drive the swing mechanism 300 and the substrate 110 as a whole to move back and forth along the track 121.

[0052] Figure 4 This is a schematic flowchart illustrating a seat control method provided in an embodiment of this application. This seat control method is applied to, for example... Figure 1-3 In any of the seats described above, the seat is provided with two sliding grooves, and each sliding groove is provided with a corresponding rocking mechanism.

[0053] In this embodiment of the application, the vehicle seat control method may include the following steps.

[0054] S101, Obtain the physiological parameter information of the object on the seat.

[0055] In this embodiment, the seat is installed in a vehicle, such as a car. Sensors such as cameras or millimeter-wave radar can be installed in the vehicle to collect physiological parameter information of the occupants. This physiological parameter information includes respiratory rate, heart rate, and / or limb movement amplitude. A person's respiratory rate, heart rate, and limb movement amplitude differ in different states. This physiological parameter information can reveal the current state of the occupants in the vehicle, such as sleep state, awake state, fatigue state, and tension state.

[0056] S102, Determine the target control strategy based on the physiological parameter information.

[0057] In this embodiment, various control strategies can be pre-set based on the situation of the occupants. These strategies may include rest control strategies, wake-up control strategies, reminder control strategies, and dynamic control strategies. Specifically, a sleep state can correspond to a rest control strategy, a woke-up state to a wake-up control strategy, a fatigued state to a refresher control strategy, and a tense state to a dynamic control strategy. This allows the seat to be adjusted to better suit the occupants' needs.

[0058] S103, Generate a corresponding drive signal according to the target control strategy. The drive signal is used to control the motion direction and speed of the drive component in the two swing mechanisms.

[0059] Because the aforementioned seat is equipped with a rocking mechanism 300, it achieves gentle dynamic reciprocating rocking, which can effectively improve the riding comfort of drivers and passengers and can fully adapt to various usage scenarios such as resting, relaxing, and aiding sleep in the car.

[0060] Therefore, in this embodiment, a corresponding drive signal is generated according to different control strategies. The drive signal is used to control the movement direction and speed of the drive components in the two swing mechanisms so that the seat movement matches the current state of the occupants in the vehicle.

[0061] S104, the drive signal is used to control the movement direction and speed of the drive components in the two rocking mechanisms of the seat, so that the second end of the drive linkage corresponding to the drive component rotates around the second axis.

[0062] The driving components in the two rocking mechanisms can move in the same or different directions. For example, when they rotate synchronously and at the same speed, the seat will remain stable in the first axis direction and will not tilt. However, when they rotate asynchronously and at the same speed, the heights of the two driving mechanisms will be different, resulting in tilting. When they rotate synchronously but at different speeds, the heights of the two driving mechanisms will be different.

[0063] In another embodiment of this application, the aforementioned seat control strategy can affect the driver's operation when controlling seat movement. To ensure driving safety when controlling the seat, this embodiment of the application... like Figure 5 As shown, the method may include the following steps before step S101.

[0064] S201, Obtain the motion state of the vehicle related to the seat; S202, determine that the motion state of the vehicle related to the seat is stationary.

[0065] If so, proceed with the step of obtaining the physiological parameter information of the object on the seat; otherwise, return to step S201 to continue acquiring the motion state.

[0066] In this embodiment of the application, by limiting the seat control method to be activated only when the vehicle is parked, the seat control can be avoided while the vehicle is in motion. Since the tilting or bumping of the seat affects the driver's operation, the safety of the seat control method can be improved.

[0067] like Figure 6 As shown in this embodiment, determining the target control strategy based on the physiological parameter information in step S102 may include the following steps: S1021, Obtain the threshold range of at least one preset state of the object.

[0068] The physiological parameters include respiratory rate, heart rate, and / or limb movement amplitude. There can be multiple preset states, such as: sleep state, awake state, fatigue state, and tension state. The sleep state corresponds to a rest control strategy, the awake state to a wake-up control strategy, the fatigue state to a refresh control strategy, and the tension state to a motion control strategy.

[0069] Taking respiratory rate as an example, the respiratory rate of a normal person can be 12-20 breaths per minute. It can be divided into the following categories: 12-13 breaths per minute is the sleep state; 13-15 breaths per minute is the awake state; 15-16 breaths per minute is the fatigue state; and 16-17 breaths per minute is the tension state. In other embodiments of this application, the threshold range of respiratory rate corresponding to each state can also be set separately according to the driver's situation.

[0070] Taking heart rate as an example: the breathing rate of a normal person can be 60-100 times / minute. It can be divided into the following categories: 60-65 times / minute is the sleep state; 65-70 times / minute is the awake state; 70-75 times / minute is the fatigue state; and 75-80 times / minute is the tension state. In other embodiments of this application, the threshold range of heart rate corresponding to each state can also be set separately according to the driver's situation.

[0071] Taking the range of motion as an example, the typical range of motion for a driver's limbs is 0-50 cm. In this embodiment, the range of motion can be an average value, such as the average value within 1 minute. It can be defined as follows: 0-5 cm for a sleeping state (immobile); 30-50 cm for a waking state (stretching); 10-30 cm for a tired state (drowsy); and 5-10 cm for a tense state (tense). S1022, determine the target threshold range for each physiological parameter.

[0072] By comparing the physiological parameters with the range of the same type of physiological parameters corresponding to each preset state in the aforementioned step S1021, the corresponding target threshold range can be obtained.

[0073] For example, if the parameter for the range of motion of a limb is 35cm, then the corresponding target threshold range is 30-50cm.

[0074] S1023, determine the target state corresponding to each physiological parameter based on the target threshold range of each physiological parameter.

[0075] In practical applications, when all physiological parameters fall within the same range, the target state can be determined without question. However, different physiological parameters may fall within different ranges. In such cases, weights can be assigned to different physiological parameters. For example, the weight of limb movement amplitude can be 60%, respiration 25%, and heart rate 15%. When there are only two parameters, if the limb movement amplitude is 5-10cm, corresponding to a state of tension, but the heart rate is 70-75 beats / minute, corresponding to a state of fatigue, then the state of tension is prioritized due to the higher weight of limb movement amplitude. When there are three parameters, if two physiological parameters have the same state, the state corresponding to these two parameters is taken as the target state. If the states corresponding to the three physiological parameters are different, the state corresponding to the physiological parameter with the highest weight value is taken as the target state.

[0076] S1024, find the target control strategy corresponding to the target state.

[0077] In this embodiment, different control measures can be set according to the control intensity of the seat. For example, the control strategy may include: sleep control strategy, wake-up control strategy, alertness control strategy, and motion control strategy. Here, the control strategy of the seat is gradually strengthened according to the order of sleep control strategy, wake-up control strategy, alertness control strategy, and motion control strategy to match the physiological parameters of the current occupants in the vehicle.

[0078] Control strategies may include controlling different parameters such as seat tilt, angle, and sway amplitude.

[0079] In the embodiments of this application, a correspondence between different preset states and different control strategies can be established in advance. For example, the sleep state corresponds to the rest control strategy, the awakened state corresponds to the wake-up control strategy, the fatigued state corresponds to the energizing control strategy, and the tense state corresponds to the dynamic control strategy.

[0080] Therefore, after determining the target state based on physiological parameters, the corresponding target control strategy can be determined by looking up a table, and then the seat can be controlled according to the target control strategy.

[0081] In this embodiment of the application, taking the control strategy as including: rest control strategy, wake-up control strategy and refresh control strategy as an example, when the target control strategy is a rest control strategy, the aforementioned step S104 may include the following steps: The driving components of the two swing mechanisms are determined to run in the same direction and synchronously, and the running speed of each driving component is a first speed.

[0082] The same and synchronized operation direction means that the two drive components start simultaneously and move in unison, allowing the seat to maintain balance and prevent tilting in the first axis direction. In this embodiment, the first speed can be 30 revolutions per minute. In other embodiments, the first speed can be freely set as needed.

[0083] The seat includes a seat back that is rotatably connected to the seat body. When the target control strategy is a rest control strategy, the method may further include any of the following control methods: The movement duration of the driving component in the two swing mechanisms is determined as a third duration; the angle between the seat back and the seat body is controlled to the maximum angle; within the first duration, the vehicle is controlled to play music, and the volume of the music is within a first preset decibel range; and / or, the temperature of the vehicle is controlled to a preset temperature range and / or the humidity is controlled to a preset humidity range; and / or, the circulation mode of the vehicle is controlled to external circulation; and / or, the vehicle is controlled to activate the light-blocking mode; and / or, the outlet of the aromatherapy device of the vehicle is activated.

[0084] The third duration can be 20 minutes, meaning the seat controls will stop after 20 minutes. The first preset decibel range can be 30-35 dB.

[0085] In a specific embodiment of this application, these control methods can be combined with seat motion control to make the occupants of the vehicle more comfortable.

[0086] In this embodiment of the application, taking the control strategy as including: rest control strategy, wake-up control strategy and energization control strategy as an example, when the target control strategy is the wake-up control strategy, the aforementioned step S104 may include the following steps: The driving components of the two swing mechanisms are determined to have the same and asynchronous running direction. The speed of each driving component within the first time period after starting is the first speed, and the speed after the first time period is the second speed, which is greater than the first speed.

[0087] Asynchronous means that the start times of the two drive components are different. For example, after one drive component starts, it runs for 0.5 seconds, and then the other drive component starts to move. In this way, even if the two drive components move at the same high speed, their pace is not consistent, which allows the seat to tilt and change its angle in the first axis direction.

[0088] In this embodiment, the second movement speed can be 60 revolutions per minute. The first duration can be 2 seconds.

[0089] The seat includes a seat back that is rotatably connected to the seat body. When the target control strategy is a wake-up control strategy, the method may further include any of the following control methods: The angle between the seat angle and the seat body is controlled within a preset angle range. In the embodiments disclosed in this application, the preset angle range is 40 degrees to 60 degrees, preferably 45 degrees; the vehicle is controlled to play music, and the volume of the music is in a second preset decibel range; and / or, the air conditioning duct of the vehicle is controlled to be at its maximum windshield; and / or, the vehicle is controlled to turn off the shading mode; the first preset decibel range is greater than the first preset decibel range.

[0090] In this embodiment of the application, the first preset decibel range can be 30-35 dB, and the second preset decibel range can be above 35 dB.

[0091] In a specific embodiment of this application, these control methods can be combined with seat motion control to make the occupants of the vehicle more comfortable.

[0092] In this embodiment of the application, taking the control strategy as including: rest control strategy, wake-up control strategy and refresh control strategy as an example, when the target control strategy is a reminder mode, the aforementioned step S104 may include the following steps: The driving components of the two swing mechanisms are determined to run in opposite directions and synchronously, and the speed of each driving component is a second speed.

[0093] When the directions of operation are opposite and synchronized, the seat will exhibit a wavy effect in the direction of the first axis, meaning that the left and right heights are not synchronized and change periodically with rotation.

[0094] When the target control strategy is an alert control strategy, the method may further include the following control methods: The motion duration of the driving component in the two swing mechanisms is determined to be the fourth duration; after the fourth duration, the vehicle is controlled to play a preset prompt sound, which lasts for a fifth duration.

[0095] In this embodiment of the application, the prompt sound can be a "beep beep" sound, and the duration of the fifth prompt can be 10 seconds.

[0096] In a specific embodiment of this application, these control methods can be combined with seat motion control to make the occupants of the vehicle more comfortable.

[0097] In other embodiments of this application, taking the motion control strategy as an example, the aforementioned seat control method may further include the following steps.

[0098] Obtain the music beat of the environment in which the seat is located; The corresponding drive signal is generated according to the target control strategy; It is determined that the driving components of the two swing mechanisms run in the same direction and are synchronized. The running speed of each driving component is determined as a third speed according to the music beat. The third speed is equal to a preset multiple of the music beat multiplied by the second speed.

[0099] In this embodiment, the second speed can be 30 revolutions per minute. Taking a music beat of 120 BPM as an example, this is equivalent to twice per second. Therefore, by multiplying the preset multiple of the music beat by 30 revolutions per minute, the third speed can be obtained. The seat moves at the third speed, which is more in line with the beat.

[0100] Thirdly, embodiments of this application provide an electronic device, the electronic device including a processor. The processor is configured to perform any of the preceding seat control methods.

[0101] Fourthly, this application provides a vehicle, which includes a seat as described in any of the preceding claims, and electronic equipment as described in the preceding claims. The electronic equipment controls the drive mechanism in the seat.
