Rotate around one shaft 25 to stand up. Further, as shown in FIG. 2, when the first board 20 is raised, the corner of the first board 20 on the first shaft 25 side comes into contact with the convex part 24 of the rear floor panel 22 and does not rotate any more. It has become.

  As shown in FIG. 4, the third board 18 is pivotally supported via a pair of hinges 26 at the vehicle front portion of the first board 20. As shown in FIG. 8, in the hinge 26, a pair of connection plates 26 </ b> A and a connection plate 26 </ b> B are axially supported via a connection pin 26 </ b> C, and the connection plate 26 </ b> A is screwed to the first board 20 from the lower surface. The connecting plate 26B is fixed to the vehicle rear portion of the third board 18. In the flat state in which the top surfaces of the third board 18 and the first board 20 function as a lid of the underfloor storage portion 23 at a position where the floor surface 21 constitutes, the connecting pin 26C that connects the connecting plate 26A and the connecting plate 26B is It is located on the lower surface and is not exposed on the upper surface of the floor surface 21. Further, in this flat state, the vicinity of the connecting portion between the first board 20 and the third board 18 is placed on the bracket 22 </ b> A erected from the rear floor panel 22.

  As shown in FIGS. 3 and 4, a stepped portion 30 is formed at the vehicle front end portion of the opening edge 23 </ b> A of the underfloor storage portion 23 closed by the third board 18 so that the vehicle front portion of the third board 18 is placed thereon. It has become. Further, the stepped portion 30 is also provided at both ends of the opening 23A in the vehicle width direction, and here, guide rails 32 are provided as a pair of guide means whose longitudinal direction is the vehicle front-rear direction.

  As shown in FIG. 9, the guide rail 32 includes a U-shaped portion 32A having a groove-shaped cross section in the longitudinal direction, and flanges 32B protrude vertically from both ends of the U-shaped. A push block 42 is mounted in the U-shaped portion 32A so as to be slidable in the longitudinal direction. Further, a through-groove 36 extending in the vehicle front-rear direction is formed on the standing wall of the U-shaped portion 32A, and the through-groove 36 projects from the side surface of the front portion of the third board 18 in the vehicle width direction. A cylindrical guide pin 34 is inserted. The inserted guide pin 34 engages with the semicircular recess 42A of the push block 42. Furthermore, one end of a compression coil spring 38 as a driving means is attached to the front portion of the push block 42 in the vehicle, and the other end of the compression coil spring 38 is accommodated in a bracket 40 fixed to the vehicle body. As a result, the compression coil spring 38 can be expanded and contracted in the vehicle front-rear direction with the bracket 40 as the base end portion, and the third board 18 is pushed rearward through the guide pin 34.

  At the position where the top surface of the third board constitutes the floor surface 21, the guide pin 34 is located in the vehicle front direction shown in FIG. In this position, the compression coil spring 38 is compressed and biases the guide pin 34 toward the first shaft 25 that is the shaft support portion of the first board 20. The urging force is limited by a stopper lever 46 as a limiting member shown in FIG. 9 disposed in the vehicle rearward direction of the guide pin 34.

  The stopper lever 46 is an arc-shaped part in a side view, and the tip end portion 46A is in contact with the guide pin 34 in a flat state. Further, the base end portion of the stopper lever 46 is rotatably supported by a stopper base 44 fixed to the vehicle body. Further, a first solenoid 48 is disposed at the vehicle lower portion of the stopper lever 46, and the first solenoid 48 contacts the guide pin 34 by rotating the tip 46A of the stopper lever 46 downward when energized. It has the role of retracting to a position where it is not.

  For this reason, the first solenoid 48 is attached to the vehicle front portion of the underfloor storage portion 23 based on a signal from the first switch 52 attached to the vehicle body of the back door 14 shown in FIG. Energization is controlled by the first control device 50. The first switch 52 outputs a signal to the first control device 50 when the back door 14 is opened and reaches a predetermined opening (for example, a half-open state of ½ of the door opening / closing angle). The first control device 50 to which the signal is input energizes the first solenoid 48, and the rod 27 shown in FIG. 9 rotates the stopper lever 46 via the link 48A to retract to a position where it does not contact the guide pin 34. As a result, the guide pin 34 is pushed by the push block 42 urged by the compression coil spring 38 and guided in the vehicle rearward direction by the through groove 36. The stopper lever 46 returns to a position where it comes into contact with the guide pin 34 when the first solenoid is de-energized after the guide pin 34 passes and the rod 27 is moved to the original position by the spring 19. Since the stopper lever 46 has an arc shape, when the guide pin 34 moves from the rear of the vehicle to the front of the vehicle, the spring 19 is deformed and rotated to enable the guide pin 34 to move.

  A locking groove 36A bent downward is formed at the terminal end of the through groove 36 at the rear of the vehicle, and serves as a locking means. As indicated by an imaginary line (two-dot chain line) in FIG. 9, when the guide pin 34 is pushed by the push block 42 and reaches the rear end of the through groove 36, the guide pin 34 falls and moves into the lock groove 36A under its own weight. The vehicle cannot move in the longitudinal direction and the downward direction. As a result, the guide pin 34 is locked and the vehicle front portion of the third board 18 is fixed.

  When the guide pin 34 moves in the through groove 36, the vehicle front portion of the third board 18 moves in the vehicle rearward direction. The vehicle rear portion of the third board 18 is rotatably connected to the vehicle front end portion of the first board 20 by a hinge 26, and relatively rotates together with the vehicle front portion of the first board 20 to move upward in the vehicle. As a result, the first board 20 rotates around the first shaft 25 as a rotation axis and stops in an upright state where the first board 20 becomes a backrest. Here, since the vehicle front portion of the third board 18 is locked, the third board 18 holds the first board 20 as a holding means at a position where the back of the auxiliary seat is used.

  As shown in FIGS. 1 and 4, the first board 20 is formed with an opening 20A, and a rectangular second board 54 is accommodated in the opening 20A. As shown in FIGS. 20 and one plate. On the floor surface side of the vehicle front portion of the second board 54, a concave handle 72 that can be inserted and gripped is integrally formed. As shown in FIG. 11, a shaft hole 53 is formed in the opening 20A of the first board 20, and the columnar second projecting from the rear side surface of the second board 54 is formed in the shaft hole 53. A shaft 55 is inserted. The second shaft 55 is provided with a torsion coil spring 56. The torsion coil spring 56 projects the second board 54 from the first board 20 to form a seat surface (clockwise in FIG. 2). In the direction of rotation). The urging force is limited by a hemispherical ball pin 60 protruding from the side surface of the front portion of the second board 54 shown in FIG.

  The ball pin 60 is pressed by the spring 61 and meshes with the recess 76 provided in the opening 20 </ b> A of the first board 20, thereby fixing the first board 20 and the second board 54, and the torsion coil spring 56. The second board 54 is restricted so as not to rotate even if there is an urging force of. Further, a second solenoid 74 is attached to the base end portion of the ball pin 60, and when the second solenoid 74 is energized, the ball pin 60 is retracted against the urging force of the spring 61 and slides inward in the vehicle width direction. To do.

  The second solenoid 74 is controlled by the second control device 62 attached to the vehicle rear portion of the underfloor storage portion 23 based on the signal of the pressure switch 64 shown in FIG. The pressure switch 64 is attached to the front front surface of the first board 20.

  Further, a push plate 68 is attached to the back surface of the third board 18 by a rivet 66, and the third board 18 and the first board 20 rotate relative to each other so that the first board 20 rises and the back of the auxiliary seat is supported. The pressure switch 64 is pushed by the push plate 68 when moved to the position. That is, it moves from the state shown in FIG. 7 (A) to the state shown in FIG. 7 (B), and the third board 18 and the first board 20 are attached to the rear rear surface of the vehicle as the rear surfaces of the third board 18 and the first board 20 approach each other. Push plate 68 pushes pressure switch 64. As a result, the pressure switch 64 sends a signal to the second control device 62, and the ball pin 60 shown in FIG. 10 is pulled inside the vehicle. The ball pin 60 is not engaged with the recess 76, and the second board 54 is rotated from the FIG. 2 to the seat surface state by the urging force of the torsion coil spring 56. A cushion plate 58 is attached to the back surface of the second board 54, and the second board 54 rotates until the back surface faces upward in the vehicle and becomes a substantially horizontal state, and forms a lower end edge of the opening 16. By coming into contact with the member 70, it stops at the position that becomes the seating surface shown in FIG.

  The operation of this embodiment will be described.

  In the auxiliary seat luggage compartment structure of the present embodiment, when the back door 14 is opened and a predetermined opening (for example, a half-open state) is reached, the first solenoid 48 rotates the stopper lever 46 downward in the vehicle, The tip 46A is retracted to a position where it does not contact the guide pin 34. Accordingly, the guide pin 34 of the third board 18 is guided in the vehicle rearward direction by the urging force of the compression coil spring 38, and the vehicle front portion of the third board 18 moves in the vehicle rearward direction. The vehicle rear portion of the third board 18 rotates relative to the vehicle front portion of the first board 20 and moves upward in the vehicle. On the other hand, when the guide pin 34 is pushed by the push block 42 and reaches the rear end of the through groove 36, the guide pin 34 falls and moves into the lock groove 36A by its own weight. In this state, the guide pin 34 cannot move in the vehicle front-rear direction and the downward direction. . In this position, the third board 18 holds the first board 20 in an upright state that serves as a backrest for the auxiliary seat.

  When the first board moves to an upright state where it is a backrest, the pressure switch 64 attached to the back surface of the first board 20 on the front side of the vehicle is pushed by the push plate 68, thereby protruding from the side surface of the second board 54. The ball pin 60 is slid inward in the vehicle width direction by the second solenoid 74, and the second board 54 is released from the first board 20 and is rotated by the urging force of the torsion coil spring 56. Stop at the position. Thereby, the auxiliary sheet shown in FIGS. 1 and 4 is formed.

  When the first board 20, the second board 54, and the third board 18 are moved to a state where the top surface constitutes the floor surface 21, the second board 54 is raised and stored in the first board 20. Since the ball pin 60 protruding from the side surface of the second board 54 has a hemispherical shape, it moves by the spring 61 when it reaches the recess 76 of the first board 20 while moving inward along the shape of the vehicle. Returning to the convex position, the second board 54 is fixed to the first board 20.

  By grasping the handle 72 of the second board 54 and pulling it in the substantially rearward direction (arrow A direction) shown in FIG. 2, the guide pin 34 is moved in the substantially upward direction (arrow B direction), and the guide pin 34 is locked. By pushing the handle 72 forward of the vehicle while retracted from the groove 36A, the vehicle front portion of the third board 18 is moved forward of the vehicle (arrow C direction). As a result, the guide pin 34 is moved forward along the through groove 36. The guide pin 34 is guided in the front direction of the vehicle, abuts against the stopper lever 46, and the guide lever 34 further moves forward of the vehicle as the stopper lever 46 rotates by deforming the spring 19. When the guide pin 34 passes through the stopper lever 46, the stopper lever 46 is returned to the original position by the spring 19 and restricts the movement of the guide pin 34 to the rear of the vehicle. At this position, the top surfaces of the third board 18 and the first board 20 constitute a floor surface 21.

  Therefore, according to the auxiliary seat luggage compartment structure of the present embodiment, when the auxiliary seat is not used, the auxiliary seat does not project from the luggage compartment space 12 and the luggage compartment space 12 is not narrowed.

  Furthermore, since each member that holds the seat surface, the backrest, and the backrest of the auxiliary seat is a member that constitutes the floor surface, the number of parts can be reduced and the structure is inexpensive.
