A shock mitigation seat 10 includes a plurality of individual shock absorbing members 16 resilient to compression from a shock impact. The shock absorbing members 16 are positioned one adjacent another and such that at a certain stage of compression an individual shock absorbing member 16 resiliently deforms and comes into contact with one or more adjacent individual shock absorbing members 16 which thereby increases resistance to further compression. The seat may be incorporated in a shock mitigation system 50 which has at least one sensor operable to detect a force and to provide a feedback signal indicative of the nature of the force and a memory record the incidence and severity of these forces and provides an indication of cumulative forces absorbed.

A seat with an alertness-maintaining device that can efficiently secure a drive source (for example, a motor) when the drive source is internally housed and a vibratory stimulus is imparted to the occupant. The present disclosure relates to a seat with an alertness-maintaining device, the seat being provided with an alertness-maintaining device for imparting physical force to the occupant to promote alertness. A load-supporting portion for supporting the load on the back of the occupant is installed, and a device drive unit for imparting physical force to the occupant, the device drive unit that forms the alertness-maintaining device, is attached to the load-supporting portion. The device drive unit is provided with a drive source and a support member. The support member is attached to the load-supporting portion while grasping a part of the load-supporting portion by a drive source attachment surface portion and a load-supporting portion-clamping piece.

An awakening inducing device induces a vibration device disposed in a seat at a position where the vibration device opposes at least one of a muscle belly portion or an insertion portion of a hamstring of a user sitting on the seat; and a control device that, by controlling the vibration device, causes the vibration device to given vibration stimulation to at least one of the muscle belly portion or the insertion portion.

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 performing 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 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.

A vehicle passenger detection device, a system including the same, and a method thereof are provided. The vehicle passenger detection device includes a processor configured to determine a location of a passenger per at least one or more seats based on strength of radar signals reflected from the at least one or more seats including medium with different reflection characteristics and a storage storing information associated with strength of a radar signal for each distance and information associated with strength of a radar signal according to the reflection characteristics of the medium.

An embodiment vibration motor assembly of a seat includes a vibration motor and an upper housing disposed around the vibration motor to hold and fix the vibration motor, the upper housing configured to be fixed to a pad of the seat, and the upper housing including a holding part disposed at a circumference of a front surface of the upper housing to hold a circumference of the vibration motor and a fixing part protruding from a rear surface of the upper housing to cover and fix a rear surface of the vibration motor.

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.

A vehicle seat comprises at least one vibration device comprising an electroacoustic transducer, the vibration device having a mass less than or equal to 130 g.

A vehicle seat includes: a pressure sensor capable of measuring a pressure distribution on a surface of the vehicle seat; a plurality of actuators provided in the vehicle seat; and a controller that controls vibrations generated by the plurality of actuators based on the pressure distribution output by the pressure sensor.

The present disclosure relates to a vibration generating apparatus for a vehicle including a state analysis device that generates analysis information based on the state information, a vibration signal modeling information generation device that generates vibration signal modeling information for the vibration of the vehicle based on the generated analysis information, and a vibration signal generation device that generates a vibration signal based on the generated vibration signal modeling information and driving information of the vehicle.
