A vehicle system includes a seat of a vehicle, and a vibration generation device provided in the seat. The vibration generation device includes a housing, a diaphragm supported on the housing, an actuator attached to at least one of the housing and the diaphragm, and a sensor, including a detection electrode, and configured to detect a user approaching the detection electrode. The diaphragm and the detection electrode are famed by a common member.

A driving assistance device includes a vibration-imparting unit to impart vibration to at least one of a seat and a seat belt on the side of a driver of a vehicle, and a control unit to, after the vehicle is transitioned to a movable state by start of driving assistance of the vehicle, notify the driver that it is ready to accept an operation by controlling the vibration-imparting unit to impart vibration to at least one of the seat and the seat belt.

A housing for a vibration unit which can be arranged on a seat cushion of a vehicle seat and is intended to generate a haptically detectable signal at the vehicle seat. In order to enhance the driving experience of an occupant, in particular a driver, of a vehicle, the housing has an edge-free surface and at least one housing opening, which is permeable to sound waves.

Disclosed is a child safety system for a vehicle that can alert a driver of the vehicle about the presence of a child in the vehicle when the door of the vehicle is opened. The disclosed child safety system includes a plurality of weight sensor pads that can connect with different seats of the vehicle. The plurality of sensor pads can connect to a central unit through a splitter. The central unit includes an audio alarm, a light source, and a battery. The disclosed system further includes a magnetic door switch that can be installed on the driver's side door for detecting the opening of the door. The magnetic door switch can also be electrically connected to the central unit.

A car seat includes an actuator capable of changing an orientation of a rest surface of a seat back laterally by turning and moving at least a side portion frame that is part of the car seat frontward and rearward, and a controller configured to exercise control over the actuator. The controller includes a run-time posture support unit configured to execute a run-time posture support control under which when a car makes a turn, the actuator is regulated to cause the rest surface of the seat back to be oriented in a direction of the turn. The run-time posture support unit is configured to regulate the actuator in accordance with a placement of the seat in the car, when the run-time posture support unit executes the run-time posture support control.

The present disclosure provides a chair in which attachment strength of a holding member and the chair is enhanced and an attachment state can be stably maintained. A legged chair includes a leg member, a support post connected to the leg member, a metal frame integrated with the support post, the metal frame forming a seated portion, an awakening device configured to awaken a seated person, a battery configured to supply electric power to the awakening device, an ECU that controls the awakening device, and a holding cover configured to hold the battery and the ECU. The holding cover is attached to the highly rigid metal frame.

A safety device for a motor vehicle seat comprising: a seat, an electric motor for moving the seat or a part of the seat, and a control device configured for measuring/detecting at least one operating parameter of the motor among the voltage and/or the current of the motor and/or the speed of the motor, when the seat or the part of the seat is moving along a movement path when actuated by the motor, the control device being configured for ensuring that the motor is stopped when the at least one parameter of the current measurement crosses at least one threshold.

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.

Systems and methods for enhanced vehicle audio seat vibration with individual passenger controls. An example system includes a controller configured to obtain an input audio signal. The controller filters the input audio signal via one or more filters, with the one or more filters including a low-pass filter. The controller is in communication with a multitude of intensity controllers usable by respective persons within a vehicle, with the intensity controllers specifying respective intensities. The controller configures an amplifier based on the respective intensities, and the amplifier causes output from seat exciters configured for mounting on seats of the persons.

The present disclosure provides a chair in which attachment strength of a holding member and the chair is enhanced and an attachment state can be stably maintained. A legged chair includes a leg member, a support post connected to the leg member, a metal frame integrated with the support post, the metal frame forming a seated portion, an awakening device configured to awaken a seated person, a battery configured to supply electric power to the awakening device, an ECU that controls the awakening device, and a holding cover configured to hold the battery and the ECU. The holding cover is attached to the highly rigid metal frame.
