Description

Title of the invention: MOTOR VEHICLE COMPRISING AN AUTOMATIC FOOTREST FOR A VEHICLE PASSENGER

[0001] The invention relates to comfort equipment for occupants of motor vehicles.

[0002] Prior art patent application KR20080002381 is known, describing a footrest for a motor vehicle. The footrest is positioned at the driver's seat, near the brake pedal, accelerator pedal, and / or clutch pedal. The footrest comprises a base and a support plate. Furthermore, the footrest includes a return spring positioned under the base and under the support plate. The footrest also includes a vibrator positioned towards the bottom of the support plate. However, a drawback remains. The footrest is manually operated. The driver must manually press down on the support plate to activate the footrest's vibrator. This can distract the driver while driving and increase the risk of a traffic accident.

[0003] The objective of the present invention is to remedy these drawbacks and to reduce the risks of insufficient blood circulation in passengers automatically.

[0004] To achieve this objective, the invention proposes a motor vehicle comprising at least one passenger seat, the vehicle comprising a footrest configured to activate the blood circulation of a passenger, said footrest being positioned opposite the passenger seat, notable in that the vehicle comprises a controller configured to communicate with the footrest, said controller also being configured to communicate with a health data collection means itself configured to measure the passenger's blood pressure, heart rate, perspiration rate and / or body temperature, said health data collection means being internal or external to the vehicle, said footrest comprising a vibrator and / or a sliding device configured to raise the passenger's feet,said vibrator and / or said sliding device being capable of activating when blood pressure is below a first predetermined threshold value, when heart rate is below a second predetermined threshold value, when the perspiration rate is below a third predetermined threshold value, and / or when body temperature is below a fourth predetermined threshold value.

[0005] Automatic activation of the vibrator and / or the footrest sliding device when insufficient blood circulation in the passenger is detected allows immediately relieve the passenger before insufficient blood circulation causes further symptoms.

[0006] Preferably, the means for collecting health data is internal to the vehicle, said means for collecting health data being a camera comprising at least one blood pressure sensor, one heart rate sensor, one perspiration sensor and / or one passenger body temperature sensor.

[0007] Such a device makes it possible to measure the passenger's health data in a non-invasive manner and without direct contact with the passenger's skin, which improves passenger comfort.

[0008] Alternatively, the health data collection means is internal to the vehicle, said health data collection means being positioned in the passenger seat, said health data collection means being a blood pressure sensor, a heart rate sensor, a sweat sensor and / or a passenger body temperature sensor.

[0009] The sensors included in the passenger seat are reliable because the passenger's position does not affect the measurement of health data.

[0010] Alternatively, the means of collecting health data is a smart watch comprising at least one blood pressure sensor, one heart rate sensor, one perspiration sensor and / or one passenger body temperature sensor.

[0011] The watch is in direct contact with the passenger's skin, which improves the accuracy of health data measurements by the sensors.

[0012] Preferably, the controller is configured to communicate with a mobile terminal, the vibrator and / or sliding device being activatable by touch or voice command from the passenger from the mobile terminal.

[0013] The passenger can thus activate the vibrator and / or the footrest sliding mechanism for their comfort, even before insufficient blood circulation is detected. Furthermore, they can manage the different footrest modes, for example, activating or deactivating the vibrator, according to their preferences.

[0014] Preferably, said vehicle includes a passenger event planning tool, the vibrator and / or sliding device being activated automatically after an event when the vehicle is in an operating state.

[0015] In this way, the vibrator and / or the footrest sliding device activates automatically after an event likely to cause insufficient blood circulation, in order to prevent it.

[0016] Furthermore, the invention relates to a method for activating a vibrator and / or a sliding device for a footrest in a motor vehicle, described previously, notable in that the method comprises the following steps: - a step of collecting at least one health data point by means of health data collection, the health data being chosen from blood pressure, heart rate, sweat rate and / or body temperature of the passenger, the health data being transmitted to the controller; - a step of activating the vibrator and / or the sliding device when blood pressure is below a first predetermined threshold value, when heart rate is below a second predetermined threshold value, when the perspiration rate is below a third predetermined threshold value, and / or when body temperature is below a fourth predetermined threshold value.

[0017] The invention will be further detailed by describing a non-limiting embodiment, and based on the attached figure illustrating an embodiment of the invention, in which [Fig. 1] schematically illustrates, in the form of a flowchart, the interactions between a footrest, a motor vehicle controller, and a means for collecting health data to implement a method for activating a vibrator and / or a sliding device of a footrest in a motor vehicle.

[0018] The invention relates to a motor vehicle comprising at least one passenger seat and a footrest RP. The footrest RP is positioned at the level of the passenger seat, opposite it. The role of the footrest RP is to activate blood circulation for a passenger when the passenger is seated in said passenger seat. The footrest RP includes a vibrator and / or a sliding device. The vibrator stimulates muscle tissue and blood vessels to facilitate blood circulation. Elevating the passenger's feet reduces venous pressure, thus preventing dilation of the passenger's veins and, consequently, insufficient blood circulation. The sliding device is designed to cause the passenger's foot(s) to slide upwards, thereby elevating them to promote blood circulation.Furthermore, the vehicle includes a controller C configured to interact with said footrest RP, but also to interact with a health data collection means MC, internal or external to the vehicle, as illustrated in [Fig. 1]. The health data collection means MC is configured to measure a health data selected from blood pressure, heart rate, perspiration rate, and / or the passenger's body temperature. In a first embodiment, said vehicle includes the health data collection means MC. In other words, said health data collection means MC is internal to the vehicle. In this case, said health data collection means MC is a camera comprising a blood pressure sensor, a heart rate sensor, a perspiration sensor, and / or a passenger body temperature sensor. It may be a multifunction camera. For example, . Advantageously, the camera is configured to monitor the driver and / or passengers, in particular to detect signs of drowsiness in the driver. Alternatively, the health data collection device is located in the passenger seat of the vehicle. In this case, the health data collection device is a blood pressure sensor, a heart rate sensor, a perspiration sensor, a passenger body temperature sensor, or a combination of these sensors. In a second embodiment, the health data collection device is external to the vehicle. For example, the health data collection device is a smartwatch that includes at least one blood pressure sensor, a heart rate sensor, a perspiration sensor, a passenger body temperature sensor, or a combination of these sensors.Thanks to these sensors, it is possible to determine whether or not the passenger is suffering from insufficient blood circulation, and to activate the vibrator and / or the sliding device to improve the passenger's blood circulation. Indeed, the vibrator and / or the sliding device activates automatically when blood pressure is below a first predetermined threshold value, when heart rate is below a second predetermined threshold value, when the perspiration rate is below a third predetermined threshold value, and / or when body temperature is below a fourth predetermined threshold value.

[0019] Indeed, the invention also relates to a method for activating the vibrator and / or the sliding device of the footrest RP in the motor vehicle described above. The method includes a step of collecting at least one health data point chosen from among the passenger's blood pressure, heart rate, perspiration rate, and / or body temperature. The controller C is capable of communicating with the health data collection means MC; the collected health data point(s) are then transmitted to the controller C, as illustrated in [Fig. 1].During a detection phase, insufficient blood circulation is detected in the passenger when blood pressure is below a predetermined threshold value, when heart rate is above a predetermined threshold value, when perspiration rate is above a predetermined threshold value, and / or when body temperature is below a predetermined threshold value. Indeed, poor blood circulation leads to a decrease in blood pressure, heart rate, perspiration rate, and body temperature due to impaired venous return in the legs. The RP footrest aims to promote this venous return and thus correct these changes. During an activation phase, the vibrator and / or sliding mechanism is activated when blood pressure... is below a first predetermined threshold value, when the heart rate is below a second predetermined threshold value, when the sweat rate is below a third predetermined threshold value and / or when the body temperature is below a fourth predetermined threshold value.

[0020] Furthermore, the controller C is preferably capable of communicating with a mobile terminal T. This interaction between the mobile terminal T and the controller C is illustrated in [Fig. 1]. The mobile terminal T is, for example, a mobile phone. Thus, the passenger can activate the vibrator and / or the sliding mechanism of the footrest RP from their mobile terminal T, for example, by touch or voice command. Preferably, when the footrest RP includes both the vibrator and the sliding mechanism, the passenger can activate said vibrator and / or sliding mechanism, either alternately or simultaneously. Optionally, the mobile terminal T includes an event scheduling tool, which may be in the form of a calendar, for example. The vibrator and / or sliding mechanism then activates automatically after an event and when the vehicle is in operation.For example, when a passenger plans a hike, they can create an event in the event scheduling tool by specifying the date and time the hike should end. Then, at the end of the hike, the passenger enters the vehicle and sits in the passenger seat. The driver's activation of the vehicle triggers the automatic activation of the vibrator and / or the sliding mechanism.

[0021] Preferably, the vehicle itself includes a passenger-operated event planning tool. The vibrator and / or sliding device activates automatically after an event when the vehicle is in operation, as previously described.
