Abstract: A seat for a passenger comprises reinforcing structure bodies reinforcing seatbacks, connection support portions connecting the reinforcing structure bodies to a vehicle-body wall portion so as to support the reinforcing structure bodies at the vehicle-body wall portion, pressure-receiving portions provided in the seatbacks and supported so as to move rearwardly by being pressed by passengers in a vehicle rear collision, the pressure-receiving portions being arranged at a specified height position which is a distance upwardly away from lower end portions of the seatbacks, and headrest moving-mechanism portions moving headrests forwardly or upwardly in accordance with a rearward move of the pressure-receiving portions. Accordingly, a passenger's head portion can be protected effectively with a simple structure.

Abstract: A seat is arranged in front of a back door. An airbag is configured to inflate into a space between the seat and the back door in a rear collision of a vehicle. Herein, when a lower frame portion of a headrest support structure body receives a rearward load in the rear collision of the vehicle, an upper frame portion of the headrest support structure body is moved forwardly around a rotational point of connecting members which pivotally connect an upper portion of the headrest support structure body to the vehicle-body side wall. Accordingly, a headrest attached to the upper frame portion is moved forwardly so that the space between the headrest and the back door can be expanded longitudinally and the passenger's head portion can be supported securely.

Abstract: A seat device for a vehicle comprises a seat for a passenger including seatbacks to support a passenger's back portion, reinforcing structure bodies provided inside the seatbacks along an outer periphery of the seatbacks, headrests provided at upper portions of the reinforcing structure bodies to support a passenger's head portion, connection support portions provided beside the reinforcing structure bodies to connect the reinforcing structure bodies to a vehicle-body member, and move-allowance portions to allow lower portions of the reinforcing structure bodies to move rearwardly in a vehicle rear collision so that the headrests move forwardly or upwardly. Accordingly, a passenger's head portion can be protected effectively with a simple structure.

Abstract: There are provided a seatback supporting backs of plural passengers seated on a bench type of seat cushion, a headrest provided at an upper portion of a first portion of the seatback and supporting a head of the passenger seated in front of the first portion, a pressure-receiving portion provided at a second portion of the seatback which is arranged beside the first portion so as to move rearwardly when being pressed by a rearward move of the passenger seated in front of the second portion, and a headrest moving mechanism provided to connect the pressure-receiving portion to the headrest so that the headrest is moved forwardly or upwardly in accordance with a rearward move of the pressure-receiving portion. Accordingly, the passenger's head can be protected with a simple structure.

Abstract: A tilt mechanism portion is connected to an front downward-extending portion of a side frame (cushion side fame) of a seat cushion so as to move vertically the seat cushion. A rear downward-extending portion of the cushion side frame is supported at a support pin of a base side frame. Thereby, the rear end of the seat cushion changes little longitudinally despite the vertical movement (tilt) of the front portion of the seat cushion. Accordingly, any conformability deterioration that may be caused by a large forward movement of the seat cushion at a seat back taking a large reclining position can be prevented properly.

Abstract: When a seat back in a forwardly folded state is raised to a predetermined raised state by activating an electric motor by turning on a switch, the electric motor is immediately stopped even if the switch is still turned on, and the seat back is retained in the raised state. There are provided a locking member which operates to retain the seat back in the raised state when the seat back is in the predetermined raised state and a lever which turns in association with the operation of the locking member. The lever turns on another switch to open a drive circuit for the electric motor.

Abstract: In an armrest structure for a vehicle seat, an armrest is mounted at a mounting portion on the outboard side of a seat back and is arranged close to a door trim panel. The armrest is capable of moving inboard upon receipt of an inboard load.

Abstract: A seat for a vehicle comprises a seat cushion, a seat back, a headrest having a neck-support portion, a headrest pole member to support the headrest, and a rotational support device. The rotational support device supports the headrest in such a manner that the neck-support portion of the headrest is rotated around a rotational axis that extends in substantially a width direction of the seat back and held at a specified angle relative to the seat back, wherein the headrest is its lowest position, the neck-support portion of the headrest is configured to be allowed to be rotated forward from its rearmost stored position by the rotational support device. Accordingly, a neck portion of a passenger can be supported by the neck-support portion of the headrest properly.

Abstract: A headrest-attached vehicle seat is provided in which a headrest is provided over a seat back. In the headrest-attached vehicle seat: the headrest includes a headrest body, and a neck-support portion which is provided under the headrest body; and the neck-support portion turns around a pivot which extends in the seat-width directions inside of the headrest body and moves in the front-and-rear directions, and the neck-support portion is positioned at a predetermined turning angle.

Abstract: A second row seat is guided by a vehicle-longitudinal-direction sliding mechanism and a vehicle-width-direction siding mechanism supported on the vehicle-longitudinal-direction sliding mechanism. The vehicle-width-direction sliding mechanism is configured such that a length thereof is set within a width of a recess portion formed at the bottom face of a seat cushion so as to allow the vehicle-width-direction sliding mechanism to be placed within the recess portion when the seat cushion has been moved forward and downward by a moving mechanism. Accordingly, a load floor formed by a back face of a seat back according to a forward movement of the seat back with its lower and horizontal position can be obtained.

Abstract: When a seat back in a forwardly folded state is raised to a predetermined raised state by activating an electric motor by turning on a switch, the electric motor is immediately stopped even if the switch is still turned on, and the seat back is retained in the raised state. There are provided a locking member which operates to retain the seat back in the raised state when the seat back is in the predetermined raised state and a lever which turns in association with the operation of the locking member. The lever turns on another switch to open a drive circuit for the electric motor.
