The front seat 12 and the rear seat 30 are configured such that a cushion pad made of urethane or the like is attached to a frame (not shown), and the surfaces thereof are wrapped with a skin material.

  The front seat 12 includes a front seat cushion 14 as a front seat cushion, a front seat back 16 as a front seat back supported by a rear end portion of the front seat cushion 14, and an upper end portion of the front seat back 16. And a headrest 18 provided on the head.

  The front seat cushion 14 provided on the floor 11F side includes an occupant seating seat surface 14A on which an occupant sits, and is slidable in the vehicle front-rear direction (arrows FR and RE directions) by a slide mechanism (not shown). In addition, the vehicle can be moved in the vehicle vertical direction (arrows UP and DN directions) by a vertical ajanta mechanism (not shown).

  The front seat back 16 supported by the rear end portion of the front seat cushion 14 constitutes the seat rear portion, and includes a backrest surface 16A for holding the seated occupant's back, and is tiltable. The headrest 18 is provided at the upper end portion of the front seat back 16 so as to be vertically adjustable and removable so as to support the head of the occupant.

  A link 22 is attached to a rear end portion of a frame (not shown) of the front seat cushion 14 so as to be rotatable around the axis of the hinge pin 20. The link 22 is attached to the lower part of a frame (not shown) of the front seat back 16 so as to be rotatable around a shaft 24. Both the axial direction of the hinge pin 20 and the axial direction of the shaft 24 are the vehicle width direction (arrow W direction (see FIG. 2)).

  A reclining mechanism 26 is provided at a connecting portion between the front seat cushion 14 and the front seat back 16. The reclining mechanism 26 can prevent and permit rotation of the front seat back 16 about the axis 24 in the frame (not shown), and can prevent and allow rotation of the link 22 about the axis of the hinge pin 20.

  As a result, the tilt angle of the front seat back 16 can be changed and the front seat back 16 can be locked at an arbitrary position. That is, the front seat back 16 can be adjusted in a predetermined reclining manner by rotating a frame (not shown) of the front seat back 16 around the shaft 24 by a predetermined reclining operation. As the link 22 and the frame of the front seat back 16 are rotated, the front seat back 16 can be tilted to a rearward state 16X that is flat with the front seat cushion 14 as shown in FIG. In the present embodiment, the state of the front seat 12 shown in FIG. 3 is referred to as a fully flat state. In this state, the seat surface 14A of the front seat cushion 14 and the backrest surface 16A of the front seat back 16 are substantially horizontal. It is continuous.

  In the present embodiment, a motor (not shown) is connected to the hinge pin 20 via a gear. When the switch (not shown) is operated and the motor rotates, the hinge pin 20 rotates. Yes.

  As shown in FIG. 2, a rear seat 30 that is a bench seat for three persons is disposed behind the front seat 12. The rear seat 30 includes a rear seat cushion 32 as a rear seat cushion having a seat surface 32B on which an occupant is seated, and a rear seat back 34 as a rear seat seat back supported at a rear end portion of the rear seat cushion 32 so as to be tiltable. The rear seat back 34 is configured to include a headrest 36 that is provided at the upper end of the rear seat back 34 so as to be vertically adjustable and detachable to support the head of the occupant.

  As shown in FIG. 1, the height position of the rear seat cushion 32 on the seat surface 32 </ b> B is higher than the height position of the front seat cushion 14 on the seat surface 14 </ b> A. As shown in FIG. 3, in the rearward state 16X of the front seat back 16, the rear seat cushion 32 is close to the front seat back 16 (in this embodiment, the end of the rear seat cushion 32 is the end of the front seat back 16). The front portion 32A of the seat surface 32B of the rear seat cushion 32 is disposed at a higher position than the backrest surface 16A of the front seat back 16.

  As a result, a step is formed between the backrest surface 16A of the front seat back 16 and the front portion 32A of the seat surface 32B of the rear seat cushion 32, and the front portion 32A including the front end portion of the rear seat cushion 32 can be used during occupant nap. It is for the pillow part. The step formed between the backrest surface 16A of the front seat back 16 and the front portion 32A of the seat surface 32B of the rear seat cushion 32 is the height of the pillow portion during occupant nap, so that the height becomes a preferred height as a pillow. For example, 2 cm to 15 cm is preferable. In the state shown in FIG. 3, the headrest 18 (see FIG. 1) is removed from the front seat back 16.

  As shown in FIG. 2, the rear seat cushion 32 includes a low resilience member 38 in the front portion 32A in the skin material. The low resilience member 38 is a member having a low resilience compared to other portions of the rear seat cushion 32, and for example, a low resilience urethane material, a low resilience rubber, or the like can be applied. Here, low repulsion means that the force that rebounds from other forces is small. The low repulsion member 38 of the present embodiment is easily deformed according to the pressing force, but is restored when time elapses after the pressing force is removed.

(Operation of the embodiment)
Next, the operation of the above embodiment will be described.

  The front seat 12 shown in FIG. 1 is configured such that the link 22 and the frame (not shown) of the front seat back 16 rotate around the axis of the hinge pin 20 so that the front seat back 16 is moved to the front seat as shown in FIG. The rearward state 16X continues in a flat state with the cushion 14, and becomes a full flat state.

  In this state, the front seat back 16 and the rear seat cushion 32 are close to each other, and the front portion 32A of the seat surface 32B of the rear seat cushion 32 is disposed at a higher position than the backrest surface 16A of the front seat back 16 to form a step. Therefore, when the occupant P takes a nap in the vehicle 10, the occupant P lies on the front seat cushion 14 and the front seat back 16, and the head is positioned in front of the seat surface 32 </ b> B of the rear seat cushion 32. It can be supported by the part 32A, and it becomes possible to take a nap comfortably. That is, the front portion 32A on the seat surface 32B of the rear seat cushion 32 can be used as a pillow. For this reason, it is possible to arrange the seat so that the passenger P can take a nap comfortably with a simple configuration without providing a special mechanism.

  Here, the rear seat cushion 32 has a front portion 32A having a low resilience member 38 that has a lower resilience than other portions, so the front of the rear seat cushion 32 with respect to the head of the occupant P in a nap position. The repulsive force of the part 32A is suppressed. Thereby, it becomes possible to provide the passenger | crew P with the space which can be used instead of a bed more comfortably.

(Other forms)
In the above embodiment, the height position of the front portion 32A on the seat surface 32B of the rear seat cushion 32 is already higher than the height position on the seat surface 14A of the front seat cushion 14 in the initial state. The seat arrangement structure for use is not limited to such a configuration, and adopts a configuration in which the front portion 32A of the rear seat cushion 32 is arranged at a higher position than the front seat back 16 in the rearward state 16X of the front seat back 16. Other forms may be obtained.

  For example, when the front seat back 16 is tilted to the rearward state 16X, the height position of the rear seat cushion 32 on the seat surface 32B is the same as the height position of the front seat cushion 14 on the seat surface 14A. Other forms such as moving the rear seat cushion 32 in the vehicle upward direction (in the arrow UP direction) by a vertical ajanta mechanism may be used.

  As another example, the front seat cushion 14 is moved in the vehicle downward direction (in the direction of the arrow DN) by a vertical ajanta mechanism (not shown), so that the front seat back 16 is in the rearward state 16X and the front seat cushion 32 is moved forward. Other forms such as arranging the portion 32A at a higher position than the front seat cushion 14 and the front seat back 16 may be employed.

  Further, in the above embodiment, the link 22 and the frame (not shown) of the front seat back 16 rotate around the axis of the hinge pin 20 so that the front seat back 16 and the front seat cushion 14 are connected as shown in FIG. Although the rearward state 16X continues in a flat state, the mechanism for bringing the front seat back 16 into the rearward state 16X is not limited to this. For example, a mechanism for rotating the frame (not shown) of the front seat back 16 around the shaft 24 and a mechanism for sliding the front seat back 16 up and down are provided. In order to eliminate the step between the backrest surface 16A of the front seatback 16 and the seat surface 14A of the front seat cushion 14, after the backrest surface 16A of the front seatback 16 is tilted substantially horizontally by rotating The front seat back 16 is slid in the vehicle downward direction (arrow DN direction) to the height position of the front seat cushion 14 so that the backrest surface 16A of the front seat back 16 continues to be flat with the seat surface 14A of the front seat cushion 14. Use the front seat bar as in the rearward state 16X. It may apply other mechanisms to the click 16 on the rear lying state 16X.

  Furthermore, in the said embodiment, although it becomes the structure which rotates the hinge pin 20 with a motor (illustration omitted), it is good also as a structure which rotates the hinge pin 20 manually.

  Furthermore, in the vehicle seat arrangement structure, a connecting mechanism for connecting these may be provided between the rear seat cushion 32 and the front seat back 16 in the rearward-turned state 16X.

  In the vehicle seat arrangement structure, a footrest may be arranged on the floor 11F, and the lower part of the knee of the occupant P who is in a nap on the fully flat front seat 12 is supported from below. In addition, an ottoman may be disposed in front of the front seat cushion 14.

  In the above-described embodiment, the two-row seat type vehicle 10 has been described as an example. However, even in the case of a multi-row seat type vehicle (for example, a three-row seat type) other than the two-row seat type, at least 1 If the pair of seat cushions and the seat back can be made to be flat (continuously flat), it can be applied to a vehicle seat arrangement structure. In this case, the front seat cushion and the front seat back may be seat cushions and seat backs in the second and subsequent rows as long as the rear seat cushion is disposed at the rear.
