Description

  The present invention relates to a vehicle seat structure, and more particularly to a vehicle seat structure in which a driver can easily get on and off and in which a baggage in a passenger compartment can be easily placed.

  Conventionally, there is one in which a driver's seat is rotatably provided to facilitate getting on and off of the driver (see, for example, Patent Document 1). When this type of driver's seat opens the door opening on the side of the vehicle body, which is the driver's entrance, the driver's seat is rotated laterally from the front-facing position to the outside of the vehicle to improve the driver's boarding / exiting capability. ing. Further, in Patent Document 1, in a two-door type passenger car, a passenger seat is slidable forward to improve the passenger's ability to get in and out of the rear seat, and the passenger seat is moved forward when the passenger in the rear seat gets on and off. It has been proposed to secure a sufficient boarding / exiting space.

  In another conventional technique in which the driver's seat is provided to be rotatable, the driver can relax at rest by rotating the front of the driver's seat to the inside of the vehicle in a truck or the like as described in Patent Document 2 below. It has been proposed to be able to take a posture.

As a conventional technique for improving the passenger boarding / exiting ability other than the driver, there is a technique in which a passenger seat is rotated to the outside of a vehicle in a welfare vehicle or the like as described in Patent Document 3 below. This is, for example, in a wagon car having three rows of seats at the front and rear, folding the rear seats in the third row and moving the rear seats in the second row behind the passenger seats back to the position of the rear seats in the third row, Thereafter, the passenger seat is moved rearward and moved to the outside of the vehicle while rotating the passenger seat from the sliding door opening at the center of the vehicle body side surface.

  By the way, if the seat of the vehicle is rotated, the upper part of the seat back and the front end of the seat cushion interfere with the side wall of the passenger compartment or the adjacent seat and the rotation is restricted, so the rotation range becomes smaller and the passengers get on and off. When aiming at the vehicle, the rotation is only to the outside of the vehicle, and when aiming to improve the occupant's relaxation, the rotation range is limited only to the inside of the vehicle. In order to increase the rotation range, a space is required around the seat, and in order to provide a space necessary for the rotation of the seat in a limited vehicle interior, it is conceivable to reduce other surrounding seats. There arises a problem that the number decreases.

  In addition, there are many opportunities for a driver to get on alone for shopping and work, and the driver often gets on and off with baggage. In this case, it is possible to get on and off by providing a driver's seat so that it can rotate to the outside of the vehicle as in the past, but in general, the driver places his / her baggage in the passenger's seat and the rear seat, so the driver can save the baggage It is difficult to twist the upper body to the inside of the car while sitting on the car. The driver also twists the upper body when a child seat is set on the rear seat and a small child is seated on the child seat to care for the child while stopped. On the other hand, if the driver's seat can be rotated to the inside of the vehicle, the convenience of operation in the vehicle such as luggage storage and child care is improved, but the boarding / exiting performance is impaired. Therefore, the present invention increases the rotation range of the driver's seat without reducing the total number of occupants that can be boarded, and the driver's boarding / exiting property is good. An object of the present invention is to provide a vehicle seat structure that can be easily operated.

In the present invention, only the driver's seat is provided at the front part of the passenger compartment so as to be rotatable at one side in the vehicle width direction, and a space is formed beside the driver's seat. A rear seat that can be seated by the The driver's seat is located near the center of the passenger compartment so that the side edge inside the vehicle is along the center line of the passenger compartment or across the center line. seat forms a rearward rotatable space, the rear seats and a divided structure in the width direction, a first seat portion located behind the driver's seat, a second located at the rear of the driver's seat side of the space A dividing line between the two seats is provided at a position closer to the second seat than the center line, and the second seat is provided so as to be able to move forward and backward. A passenger seat can be configured at the forward position of the vehicle, and an occupant can be seated next to the first seat portion when the second seat portion is advanced, immediately after the second seat portion at the rear of the passenger compartment. A retractable storage seat is provided (claim 1). The passenger compartment front provided only the driver's seat, since the arranged driver's seat in the vehicle width direction closer to the center, the driver's seat is rotatable arranged without the driver interfere around even when seated. In this way, the range of rotation of the driver's seat can be increased from the rotation position toward the door opening on the outside of the vehicle to the rotation position toward the rear on the inside of the vehicle. The driver's operation inside the car is good. Further, if necessary, the passenger seat can be secured by advancing the second seat portion of the rear seat to form a passenger seat and deploying the retractable seat so that the seat can be seated.

When the storage seat is supported on the passenger compartment floor via a support mechanism at a rear position of the second seat portion at the rear of the passenger compartment, and the second seat portion is positioned beside the first seat portion. , stored in a standing posture in which superimposed with the seat back flip up the seat cushion, when said second seat part is in the advanced position, by tilting front seat cushion, you can be seated in form to deploy (claim 2 ). The retractable seat does not obstruct the advancement and retreat of the second seat portion, and a seat to replace the second seat portion can be prepared immediately beside the first seat when the second seat portion advances.

In the space next to the driver's seat, when the passenger seat is constituted by the second seat portion on the passenger compartment floor, a storage portion is set that can move to a position below the instrument panel in front of the passenger seat ( Claim 3 ). Providing a storage part next to the driver's seat is suitable for storing the driver's baggage, and moving the storage part to a position below the instrument panel allows the second seat part to move forward and forward. It does not get in the way of the passengers seated.

A slide rail is provided in the front-rear direction between a position immediately behind the second seat portion at the rear of the passenger compartment and a position below the instrument panel in front of the space next to the driver's seat, and the second seat portion is provided by the slide rail. The storage seat and the storage unit are moved (Claim 4 ). The moving mechanism of the second seat part , the storage seat and the storage part can be simplified.

  Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the seat structure of the present invention includes a driver's seat 1 provided only on one side in the width direction of the front part of the passenger compartment, and a width direction of the passenger compartment provided in the rear part of the passenger compartment behind the driver's seat 1. The rear seat 2 is wide and can be seated by a plurality of (three) passengers, and the storage seat 4 is provided behind the seat portion 2B (described later) of the rear seat 2. 6 in the figure shows an instrument panel, and a vehicle compartment space S is provided in a half of the vehicle compartment next to the driver's seat 1. The rear of the rear seat 2 forms a luggage compartment N. 1 represents a door opening formed on one side face M of the vehicle body and serving as a driver's entrance and exit. The door opening R is opened and closed by the door D. The other vehicle body side surface M1 is provided with a door opening R1 serving as an entrance to the rear seat 2 and is opened and closed by a door D1.

  The driver's seat 1 is provided with a seat back 11 on the upper rear end of the seat cushion 10 so as to be reclining, and is installed on the passenger compartment floor F via a rotating mechanism 12. The driver's seat 1 is installed at the position where the entire seat and the rotation center axis of the rotation mechanism 12 are near the center in the width direction of the passenger compartment (the virtual line CL in the figure indicates the center line). The driver's seat 1 is disposed at a position where the side edge on the vehicle inner side substantially extends along the center line CL of the passenger compartment or straddles the center line CL.

  The driver's seat 1 arranged in this manner is separated from the door D that opens and closes the door opening R formed on the side surface M of the vehicle body. Therefore, the driver's seat 1 interferes with the door D even when the driver is seated without moving the seat back 11 forward. 1 and FIG. 2, the rotation range of the driver's seat 1 is rotated from about 45 degrees to 50 degrees from the front position “a” toward the steering wheel 60 toward the outside of the vehicle. It is set in a range (white arrow E) between the vehicle outward position b facing R and the vehicle interior position d rotated about 100 to 110 degrees from the front position a to the vehicle inner side.

  The driver's seat 1 can be rotationally locked at the front position a by a lock mechanism (not shown) attached to the rotation mechanism 12 and is unlocked and rotated by operating an operation handle (not shown). Further, a locking mechanism may be provided at the positions b and d as in the position a. The driver's seat 1 can be moved in the front-rear direction by a slide mechanism (not shown) so that the driver can take his / her preferred driving position, and the movement range is obstructed to rotate in the rotation range at any position in the front-rear direction. There is no range.

  The door D is a laterally-open door hinged to the opening front edge of the door opening R, and there is a relatively wide gap with the driver's seat 1 provided near the center of the passenger compartment. A large trim pocket 7 in the shape of a storage container is provided on the vehicle compartment surface of the door D so as to project toward the vehicle compartment side and open upward.

  As shown in FIGS. 1 to 5, the rear seat 2 is provided over substantially the entire width of the passenger compartment, and the first seat portion 2 </ b> A located on the rear side of the driver seat 1 and the passenger compartment next to the driver seat 1 are provided. The space S is divided into a second seat portion 2B on the rear side. The dividing ratio of the first and second seat portions 2A, 2B is approximately 6 to 4, and the dividing line of the first and second seat portions 2A, 2B is a space S of the passenger compartment rather than the center line CL of the passenger compartment. It is provided on the side.

  The first seat 2A is installed and fixed on the passenger compartment floor at the rear of the passenger seat 1 behind the driver's seat 1. The 2nd seat part 2B is installed in the space S beside the driver's seat 1 so that it can move forward and backward (arrow F in FIG. 1).

  A pair of left and right slide rails 3, 3 extending in the front-rear direction from the lower position of the instrument panel 6 to the lateral position of the first seat portion 2 </ b> A are provided on the passenger compartment floor on the space S side of the passenger compartment. The rear ends of both slide rails 3 and 3 extend slightly toward the cargo compartment N side. The second seat portion 2B has a leg portion 23 projecting downward from the lower surface of the seat cushion 21 mounted on a slider 31 movable along both slide rails 3 and 3 (FIGS. 3 and 5). .

  The second seat portion 2B of the rear seat 2 configured as described above is normally disposed on the side of the first seat 2A and is moved forward along the slide rails 3 and 3 from the normal position so that the driver seat 1 The passenger seat is arranged sideways. The second seat portion 2B can be positioned and locked at the normal position and the forward position by a lock mechanism attached to the slider 31, and is unlocked and moved by operating an operation handle (not shown).

  On the rear side of the second seat portion 2B, there is a retractable seat 4 that can be deployed so that an occupant can sit next to the first seat portion 2A when the second seat portion 2B is moved to the forward position. It is provided. The storage seat 4 is formed of a folding seat, and includes a seat back 41 standing in a slightly tilted posture at a top end of a support leg 40 as a support mechanism, and a seat cushion 42 hinged to be pivotable in the vertical direction. The cushion 42 is displaceable between a flip-up state along the front surface of the seat back 41 and a forward-turned horizontal state. In addition, the lower end of the support leg 40 of the storage seat 4 is placed on the left and right slide rails 3 and 3 via the slider 32, and can be moved back and forth.

  The storage seat 4 normally has the second seat portion in a position immediately after the second seat portion 2B in the normal position in a state where the seat cushion 42 is lifted up and the seat cushion 42 and the seat back 41 are overlapped in the front-rear direction. It is stored along the back of the 2B seat back 22. When the second seat portion 2B is moved to the forward position, the seat cushion 42 of the storage seat 4 is moved forward to the horizontal position so that the occupant can be seated, and the entire storage seat 4 is moved to the slide rail 3. Is moved forward slightly, and a seat connected to the first seat portion 2A is formed beside the first seat portion 2A (FIGS. 4 and 5).

  When the storage seat 4 is in the unfolded state, the lower end of the auxiliary leg portion 44 extending downward from the back surface of the seat cushion 42 is brought into contact with the passenger compartment floor, and the front half portion of the seat cushion 42 is supported by the auxiliary leg portion 44. It is like that. The auxiliary leg portion 44 is pivotally supported at the upper end on the back surface of the seat cushion 42 so as to be swingable, and is stored along the seat cushion 42 in the flipped-up state when the seat is stored. The storage seat 4 can be easily displaced into the unfolded state and the retracted state by operating an operation handle (not shown).

  Further, on the side of the space S next to the driver's seat 1, it is movable back and forth along the front end portions of the slide rails 3 and 3 (arrow G in FIG. 1) and below the instrument panel 6 for storing the driver's baggage. A storage unit 5 is provided which can be stored. The storage unit 5 is a synthetic resin box having an upper opening, and is placed on the slider 33 of the slide rails 3 and 3. A concave storage portion 61 for storing the storage portion 5 is provided below the instrument panel 6 in front of the space S corresponding to the storage portion 5.

  According to the present embodiment, only the driver's seat 1 is provided at a position on one side of the front part of the passenger compartment, and the space S is provided beside the driver's seat 1, so that the degree of freedom of the installation position of the driver's seat 1 is large. The driver's seat 1 can be arranged closer to the center in the width direction of the passenger compartment. Accordingly, even if the driver's seat 1 is rotated in the seated state of the driver, the driver's seat 1 does not interfere with the door D and the like, and the rotation range can be increased. As shown in FIG. 2, when a driver rides alone for shopping or work, the driver can easily move from the door opening R which is a passenger entrance by rotating the driver's seat 1 from the front position a to the vehicle outward position b. You can get on and off. Further, since the large trim pocket 7 is provided on the passenger compartment surface of the door D that opens and closes the door opening R on which the driver gets on and off, it is convenient for storing women's handbags and pouches when getting on and off.

  When the driver gets on and off with baggage, the storage unit 5 is arranged from the storage position below the instrument panel 6 to the use position next to the driver's seat 1, and the driver's seat 1 is moved from the front position a to the inside of the vehicle. The baggage can be easily stored in and taken out of the storage unit 5 by rotating it to the vehicle interior diagonal forward position c rotated by 45 ° to 50 °, and the driver does not twist the upper body as in the past. I'm sorry. Further, if a drawer-type table that can be pulled out to the space S side is provided on the instrument panel 6 on the side of the space S next to the driver's seat 1, the driver can take notes on the table at the diagonally forward position c inside the vehicle. Can be used with a personal computer.

  In order to get a small child on board, if the child seat 8 is set on the second seat portion 2B of the rear seat 2 and is seated on the second seat portion 2B, the driver's seat 1 can be easily rotated to the inward position d. Can care for children.

When a plurality of passengers get on the vehicle, as shown in FIGS. 4 and 5, the storage unit 5 is stored in the storage position below the instrument panel 6 and the second seat unit 2 </ b > B of the rear seat 2 is operated. If it is arranged at a forward position next to the seat 1, two people can get on the driver's seat 1 and the passenger seat composed of the second seat portion 2B without a sense of incongruity. Furthermore, if the storage seat 4 is deployed so as to be able to be seated next to the first seat portion 2A with the second seat portion 2B disposed at the forward position, the storage seat 4 can be used as a part of the rear seat, Can secure the seating position for five people.

  When the occupant gets on and off the rear seat 2 side, as shown in FIG. 2, the driver's seat 1 is rotated to the vehicle outward position b, thereby improving the driver's ability to get on and off, and the driver's seat 1 and the door opening. Since an occupant getting on / off passage (arrow T) to the rear seat 2 is formed between the rear edge of R, the passenger can get on and off the rear seat 2 well.

  Since the second seat part 2B, the storage seat 4 and the storage part 5 of the rear seat 2 are movably installed on the same slide rail 3, these moving mechanisms can be simplified.

In the above-described embodiment, the rotation range of the driver's seat 1 is set to a range of about 160 degrees from the position b to the position d, but the present invention is not limited to this, and the rotation range may be 360 degrees.
