On the other hand, the lower rail 20 extending in the front-rear direction of the vehicle is fixed on the wheel house 21, and the lower rail 2
Upper rail 2 that engages with 0 and extends in the front-rear direction of the vehicle
2 is slidably supported along the lower rail 20, and is fixed to the upper surface of the upper rail 22 and has a hinge 23 having a rotation axis in the longitudinal direction of the vehicle and a seat cushion 12 extending in the vehicle width direction. They are connected by an arm 24.

A lever 26 is pivotally attached to a side surface of the upper rail 22 by a shaft 25 in the vehicle width direction, and a horizontal pin 27 is attached to the lower end of the lever 26. The lever 26 is centered on the shaft 25 by a spring (not shown). Is urged counterclockwise in FIG. 3, and the lever 26 is connected to the handle 15 by a wire 28.

Further, a plurality of recesses 30 are formed in the lock bracket 29 fixed to the lower rail 20 and extending in the front-rear direction of the vehicle at the same intervals as the recesses 19 of the anchor bracket 18 in the front-rear direction of the vehicle. The pin 27 of the lever 26 engages with one of the lock bracket recesses 30 to prevent the upper rail 22 from sliding with respect to the lower rail 20. Incidentally, 31 is an inner wall surface of the vehicle.

In the above device, the handle 15 is rotated clockwise about the shaft 14 against the urging force of the spring, and the claw portion 16 of the handle 15 is fixed to the anchor bracket 18.
When the lever 26 is removed from the recess 19 of the lock bracket 29, the lever 26 is interlocked with the handle 15 by the wire 28 and pivots about the shaft 25 in the clockwise direction in FIG. Since the lower rail 20 and the upper rail 22 are disengaged from each other, by sliding the upper rail 22 on the lower rail 20, the flip-up seat 11 can be freely displaced in the front-rear direction of the vehicle. After moving the seat 11 to an appropriate front-back position, if the hand is released from the handle 15, the urging force of the spring operates in the opposite manner to the above,
The claw portion 16 of the handle 15 engages with another recess 19 of the anchor bracket 18, and the pin 27 of the lever 26 engages with another recess 30 of the lock bracket 29, so that the flip-up seat 11 is fixed in that position. .

Therefore, since the position of the flip-up seat 11 on the floor 10 can be freely selected in the front-rear direction of the vehicle, the degree of freedom of the posture of the occupant seated on the flip-up seat 11 is increased, and the occupant's riding is improved. The comfort can be easily improved, and at the same time, the space between the passenger compartment and the rear luggage compartment can be adjusted by displacing the flip-up seat 11 in the front-rear direction, which is very convenient.

Further, after the seat back 13 of the flip-up type seat 11 arranged on the floor 10 is tilted forward and stacked on the seat cushion 12, the shaft 1 is resisted against the urging force of the spring.

By sliding the upper rails 22 upward, the flip-up seat 11 can be freely displaced in the front-rear direction of the vehicle along the inner wall surface 31, and after the flip-up seat 11 is moved to an appropriate front-rear position, Alternatively, when the handle 15 is released from the original position, the biasing force of the spring operates in the completely opposite manner to engage the pin 27 of the lever 26 with the concave portion 30 of the lock bracket 29, so that the flip-up seat 11 can be moved to its original position. It will be stored at the location.

Therefore, since the storage position of the flip-up seat 11 can be freely selected in the front-rear direction of the vehicle,
When loading luggage on the floor 1 on which the flip-up seat 11 was arranged, the flip-up seat 11 after storage
Is less likely to get in the way, and the degree of freedom in loading can be increased accordingly, and the possibility of blocking the view of the glass window arranged in the quarter part by the flip-up type seat 11 after storage is easily reduced. There is an advantage that can be made.

In the above embodiment, the claw portion of the handle pivotally attached to the seat back of the flip-up type seat is engaged with the concave portion of the anchor bracket fixed on the vehicle floor. Secure a plurality of gate-type latches on the vehicle floor and form a hook on the handle pivotally attached to the seat cushion of the flip-up seat, and selectively engage the hook with any of the appropriate latches. And / or by selectively engaging and disengaging the pins with respect to the lower rail and the upper rail for sliding the flip-up type seat in the front-rear direction of the vehicle, the relative position of the both is selectively changed. ,
Even if they can be engaged with each other at appropriate front and rear positions, the same effect as the above embodiment can be obtained.

Further, the locking mechanism for engaging and disengaging the seat back of the flip-up type seat with respect to the vehicle floor and the locking mechanism for engaging and disengaging the lower rail and the upper rail are interlocked as in each of the above embodiments.
