The first and second switches are respectively coupled operatively to the first and second restraining device, and are respectively closed when the first restraining device is in the deployed position and the second restraining device in the idle position. The alert device is thereby activable to emit an alert signal when the first restraining device is in the deployed position and the second restraining device in the idle position.

A seat includes a seating portion, a backrest, two pairs of vibrators and a vibration absorbing member, and constitutes a driver's seat of a vehicle. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the seating portion, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the backrest, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region.

A posture detection system for detecting a user's posture according to the embodiments includes a pressure sensor unit, a controller, a feedback mechanism, and a display unit. The pressure sensor unit has a sheet shape or a padded shape and includes plurality of sensors. Each of the sensors is configured to detect a pressure applied from the user. The controller is configured to classify the user's posture based on detection data detected by the pressure sensor unit. The feedback mechanism is configured to provide feedback to the user by vibrating based on a result of the classification. The display unit is configured to perform a display according to the result of the classification.

A child safety seat includes a restraining device, and an alert device and a switch serially connected in a series circuit. The restraining device includes a strap and a tether connector provided at a free end of the strap, the restraining device having an idle position and a deployed position, the restraining device being arranged in the deployed position to engage with a corresponding structure provided in a vehicle for restraining the child safety seat. The switch is operatively coupled to the restraining device and has an open state and a closed state, each of the open state and the closed state of the switch uniquely corresponding to one of the idle position and the deployed position of the restraining device. The alert device is activable to emit an alert signal when the series circuit is closed.

A child safety seat includes a base, a seat body and a notifying system. The seat body is disposed on the base and movable relative to the base between a front facing position and a rear facing position. The notifying system includes an actuated device disposed on one of the base and the seat body, an actuating component and a notifying device. The actuating component is disposed on another one of the base and the seat body and configured to actuate the actuated device when the seat body reaches at least one of the front facing position and the rear facing position. The notifying device is electrically connected to the actuated device and configured to generate a notifying signal when the actuated device is actuated by the actuating component, so as to indicate information to facilitate a caregiver to determine whether the child safety seat is installed properly.

A vehicle control system according to an embodiment of the present disclosure may include a detection unit, a control unit and a plurality of devices. The detection unit may detect an object around a vehicle to output detection information provided from the object. The control unit may provide a mode signal and a control signal corresponding to a plurality of operation modes, based on the detection information. The plurality of devices may be driven based on the mode signal and the control signal.

The vehicle control system according to the present disclosure may prevent drowsy driving on a road by allowing the plurality of devices to be driven based on the detection information provided by detecting the object around the vehicle.

A backrest of a vehicle seat comprises a backrest frame, a support plate fixed to the backrest frame, and at least one vibrating device. Each vibrating device is fixed to the support plate by means of at least one damping element. Preferably, each vibrating device is fixed on a face of the support plate opposite to the face intended to be oriented towards an occupant of the seat, at least a portion of each vibrating device being received in a respective through-hole in the support plate.

A vehicle seat element lining comprises a cushioning comprising at least one first face intended to be oriented towards an occupant of the vehicle seat and a second face, opposite the first face, the cushioning having at least one hole opening on the first and/or the second face of the cushioning; at least one vibrating device disposed in a hole, each vibrating device comprising at least two first snap-fit reliefs; a plurality of distinct vibrating device brackets, each comprising a base, overmolded by the cushioning, and a second snap-fit relief, each vibrating device being fastened to at least two respective brackets, by snap-fitting the first and second snap-fit reliefs.

In a configuration in which a holder holding a controller is mounted on a seat part with a plate-shaped member, the exposure of the mounting part of the plate-shaped member on which the holder is mounted is eliminated. A seat device includes a pressure sensor measuring a value relating to the seated person's state, a vibration imparting device a vibration imparting operation, an ECU controlling the vibration imparting device corresponding to the measurement result of the pressure sensor, a holder holding the ECU, and a mounting bracket fixed to a lower frame such that the holder is mounted on the lower frame of a seat part. The mounting bracket includes a mounting projection on which a side wall of the holder is mounted in a predetermined mounting direction. When the side wall is mounted on the mounting projection, the mounting projection is covered with the side wall.

Fatigue driving monitoring, reminding and early-warning method and system based on computer vision are provided. The system includes: a fatigue real-time monitoring system for identifying fatigue characteristic postures of a driver and obtaining a fatigue level according to frequencies of the fatigue characteristic postures and a driving time; a fatigue automatic reminding system for receiving the fatigue level, obtaining a vehicle real-time position information and providing the driver with a corresponding grade of reminder according to the fatigue level; and a fatigue information early-warning system for receiving the fatigue level and the vehicle real-time position information to obtain a fatigue safety index, so that a cloud map of fatigue road conditions is obtained according to the fatigue safety index and shared with traffic management departments and drivers for early-warning. It reduces the situation of fatigue driving on freeway and the hazard of traffic safety accidents caused by fatigue driving.
