As shown in FIG. 6, the seat cushion 13 includes a frame 23 made of a metal plate, a cushion material 24 provided around the frame 23, and a skin 25 made of a flexible material covering the cushion material 24. It comprises a cover 46 constituting the lower surface 21 of the seat cushion 13, and the cover 46 is made of the same material as the ceiling material 6 and has the same color as the ceiling material 6 as described above. Is preferred. The frame 23 includes an upper wall portion 26, a lower wall portion 27, and a side wall portion 28 that integrally connects these wall portions 26, 27. A space is partitioned inside these wall portions 26, 27, 28. ing. The pair of brackets 14 are fixed to the frame 23 integrally.

  In addition, the seat cushion 13 is provided with a plurality of lock claws 30 that can be projected and retracted from the respective side surfaces 29 thereof. In the seat cushion 13 of this example, two lock claws 30 are arranged on each side surface 29 side. As shown in FIGS. 6 and 7, each lock claw 30 is disposed on a guide member 31 fixed to the frame 23 of the seat cushion 13 so as to be slidable in the directions of arrows E and F, and the bottom of each guide member 31. A pressure spring 34 made of a compression coil spring is disposed between the wall 32 and the surface 33 of each lock claw 30 facing the bottom wall 32. As a result, each lock claw 30 occupies a position protruding outward in the vehicle width direction from each side surface 29 of the seat cushion 13 as shown in FIGS. This position of the lock claw 30 is the lock position. Each lock claw 30 is locked by a stopper (not shown) provided on the guide member 31 so as not to protrude outward from the lock position. Is held in.

  On the other hand, as shown in FIG. 6, a circular through hole 35 is formed in the lower wall portion 27 of the frame 23 of the seat cushion 13, and the circular portion 36 </ b> A of the handle 36 is rotatably fitted in the through hole 35. The knob portion 37 of the handle 36 is exposed to the outside as shown in FIG.

  As shown in FIGS. 5 to 7, one end of each wire 38 is engaged with the surface 33 of each lock claw 30, and these wires 38 are connected to the bottom wall 32 of the guide member 31 and the side wall portion of the frame 23. The other end of each wire 38 is locked to the handle 36 through the space formed in the frame 23 through the hole formed in the frame 28.

  FIG. 8 is an explanatory diagram showing the state of the seat 11 in the use position and the side panel 4 of the vehicle body 1. At this time, each of the lock claws 30 provided on the seat cushion 13 is pressed by the pressure spring 34 shown in FIGS. 6 and 7 to occupy the lock position. The engaging grooves 39 are respectively engaged with the engaging grooves 39. As a result, the seat cushion 13 and thus the entire seat 11 are locked to the vehicle body 1. In addition, at this time, the lower surface of each end portion in the width direction of the seat cushion 13 is supported by the stepped portion 40 formed on each side panel 4, and the entire seat 11 is supported by the vehicle body 1 in a stable state. In FIG. 4, the illustration of the locking groove 39 and the stepped portion 40 is omitted. Instead of forming the locking groove 39 and the stepped portion 40 in the side panel 4, a locking groove and a stepped portion are formed in an interior material (not shown) that covers the side of the vehicle interior of each side panel 4. The locking claw 30 can be engaged with each other, and the widthwise ends of the seat cushion 13 can be supported by the stepped portion. Thus, the seat 11 can also be supported on the vehicle body 1 via the interior material.

  When retracting the seat 11, the operator puts his hand under the seat cushion 13, grasps the knob portion 37 of the handle 36, and rotates it in the direction indicated by the arrow G in FIG. 5. As a result, each wire 38 is pulled in the direction indicated by the arrow H in FIG. 5, so that each lock claw 30 moves to the unlock position retracted to the seat cushion 13 side from the lock position. Thereby, each lock claw 30 comes off from the locking groove 39 formed in each side panel 4.

  After releasing the locked state with respect to the seat 11 as described above, the seat 11 is brought to the storage position shown in FIG. 3D and FIG. 4 as described above. Also at this time, the locking claws 30 protruding to the locking position by the action of the pressure spring 34 are engaged with the locking grooves (not shown) formed in the side walls of the recess 20 of the ceiling member 6, respectively. As a result, the seat 11 occupying the storage position can be locked and held on the vehicle body 1 via the ceiling material 6. When the seat 11 is brought back to the use position, the handle 36 is rotated in the same manner as described above to release the lock claws 30 from the locking grooves, thereby releasing the lock on the seat 11. What is necessary is just to descend | fall to the use position shown to (a) of FIG.

  As described above, the locking device of this example releases the engagement between the locking position protruding from the seat cushion 13 and the locking groove 39 so as to be able to engage with the locking groove 39 provided on the vehicle body 1 side. A plurality of lock claws 30 held by the seat cushion 13 so as to be movable between the unlock position retracted toward the seat cushion 13 from the lock position described above and the lock claws 30 are locked. A pressure spring 34 that urges toward the position, a handle 36 that is rotatably held by the seat cushion 13, and rotation of the handle 36 causes each lock pawl 30 to unlock against the action of the pressure spring 34. The handle 36 and the wire 38 for connecting the lock claws 30 are provided so as to move to the lock position.

  Further, in order to improve the operability when lifting the seat 11 to the retracted position, it is preferable to provide a pair of damper stays 41 between the vehicle body and each rotating arm 17 as shown in FIG. Each of these damper stays 41 includes a cylinder 42 and a rod 43 urged in a direction away from the cylinder 42 by the pressure of air sealed in the cylinder 42, and the tip of each rod 43 has a rotating arm. The base end of the cylinder 42 is rotatably connected to the side panel of the vehicle body. As a result, each pivot arm 17 is pivoted and biased in the direction indicated by the arrow J whose tip end is lifted upward. However, when the seat 11 is in the use position, the seat cushion 13 is attached to the vehicle body by the aforementioned locking device. Since the seat 11 is locked, the seat 11 is held stationary in the use position.

  FIG. 9 shows the state of the seat 11 and the rotating arm 17 when in the use position, and FIG. 10 is an explanatory view showing the state of the seat 11 and the rotating arm 17 in the retracted position. Shows the seat 11 and the rotating arm 17 by a two-dot chain line.

  As shown in FIGS. 9 and 10, the coil portion of the first torsion coil spring 44 is wound around the pin 19 that rotatably connects the rotating arm 17 and the seat back 12. One end of the first torsion coil spring 44 is locked to the seat back 12, and the other end is locked to the rotating arm 17. A coil portion of the second torsion coil spring 45 is wound around the pin 15 that connects the seat cushion 13 and the seat back 12 so as to be relatively rotatable. One end of the second torsion coil spring 45 is locked to the seat back 12, and the other end is locked to the seat cushion 13.

  When the seat 11 is in the retracted position shown in FIG. 10, the first and second torsion coil springs 44 and 45 are in a free state where no external force is applied. Therefore, when the seat 11 occupies the use position shown in FIG. 9, the second torsion coil spring 45 applies an external force in a direction to rotate the seat back 12 in the arrow K direction with respect to the seat cushion 13, The first torsion coil spring 44 applies an external force in a direction to rotate the seat back 12 in the direction of the arrow L with respect to the rotating arm 17. At this time, the seat 11 is locked to the vehicle body 1 by the above-described locking device. Therefore, the seat 11 is held immovably in its use position.

  When the lock by the above-described locking device is released, the rotary arm 17 is urged to rotate in the direction of arrow J by the damper tape 41, and the seat back 12 is moved toward the seat cushion 13 and the rotary arm 17 by arrows K and L. Since it is biased in the direction, the operator can lift the seat 11 to the retracted position with a very small force.
