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.

An arrangement structure for a biological sensor includes a biological sensor of a non-contact type provided in a seat on which a human is seated. The biological sensor detecting biological information of the human with electromagnetic waves. The biological sensor is arranged at a position in the seat avoiding a member that constitutes the seat and interferes with passage of the electromagnetic waves.

An occupant protection device, for a vehicle which protects an occupant seated on a seating surface of a seat, includes: a first push-up mechanism which pushes up a waist portion of the occupant by raising a rear portion of the seating surface; a second push-up mechanism which pushes up a thigh portion of the occupant by raising a front portion of the seating surface; and a control unit which controls operations of the first push-up mechanism and the second push-up mechanism. The control unit operates the first push-up mechanism and then operates the second push-up mechanism when an impact applied to the vehicle from the front of the seat is detected or predicted.

In a vehicle seat, a back pad outer skin covering a surface of a back pad includes a first portion covering a surface of one part, including a side face, of a bolster pad part, and second portions covering a surface of another part that is different from the one part of the bolster pad part. A bound part is formed by binding to each other mutually adjacent end parts of the first portion and the second portions and extremity parts of expansive force transmission webbings having base portions fixed to a frame, the bound part being capable of breaking when an airbag is made to expand. A non-stretchable cloth member is disposed on a reverse side of specific outer skin portions, covering a front face of the bolster pad part, of the second portions.

A cushioned device configured to prevent an occupant of a vehicle from being left unattended. The device includes a cushioned pad with a pressure sensor, a dongle, and an optimal application for receiving a pressure signal detected by the cushioned device. The application and dongle capable of generating an audible noise and associated notifications when a predetermined distance between the cushioned portion and the dongle and/or application is too great indicating that the object on the cushioned pad is now unattended. Accordingly, this system utilizes the proximity of companion devices and detected pressure signal to determine unattended occupancy in a confined space.

To improve the seated feeling of an occupant in a seat having partially different hardness, a vehicle seat includes a seat frame, an S spring which is installed on the seat frame and receives a load of an occupant, and a seat back pad which has a plurality of regions respectively formed of different materials and is disposed between a skin material of the seat and the S spring. The S spring is disposed at a position facing a boundary portion which is provided in the seat back pad and is the plurality of regions respectively formed of different materials.
