Abstract

A work vehicle includes a vehicle body, a seat section including a forward driver'"'"'s seat and a rear seat, a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in a non-use condition and a second posture where the rear seat is in a use condition, a load-carrying platform disposed rearwardly of the seat section, and a partitioning member for partitioning the seat section from a space behind the seat section. The load-carrying platform includes a forward platform and a rearward platform and is switchable in its state between an extended state where a fore/aft length of the load-carrying platform is increased after the forward platform is moved forward, and a contracted state where the fore/aft length of the load-carrying platform is decreased after the forward platform is moved rearward.

Claims

1. A pick-up style work vehicle comprising:

a vehicle body;

a seat section including a forward driver'"'"'s seat and a rear seat;

a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in a non-use condition and a second posture where the rear seat is in a use condition;

a load-carrying platform disposed rearwardly of the seat section, the load-carrying platform including a forward platform and a rearward platform, the load-carrying platform being switchable in its state between an extended state where a fore/aft length of the load-carrying platform is increased after the forward platform is moved forward, and a contracted state where the fore/aft length of the load-carrying platform is decreased after the forward platform being moved rearward, the forward platform entering a space occupied by the rear seat in the second posture when the load-carrying platform is switched to the extended state; and

a partitioning member for partitioning the seat section from a space behind the seat section, the seat back being supported by the vehicle body;

wherein the partitioning member is movable while being supported by the vehicle body between a rearwardly displaced position immediately behind the rear seat and a forwardly displaced position moved forward from the rearwardly displaced position; and

wherein the partitioning member is located at the forwardly displaced position when the rear seat is in the first posture, and the partitioning member is located at the rearwardly displaced position when the rear seat is in the second posture.

2. The pick-up style work vehicle according to claim 1, wherein the partitioning member is located forwardly of a front wall of the load-carrying platform both when the load-carrying platform is in the extended state and when the load-carrying platform is in the contracted state.

3. The pick-up style work vehicle according to claim 1, wherein the forward platform includes a front wall, forward lateral walls and a forward bottom;

and

the load-carrying platform is switched to the contracted state by pivoting the forward bottom about a transverse axis into an erected posture.

4. The pick-up style work vehicle according to claim 3, wherein when each of the front wall and the forward bottom of the forward platform is pivoted into the erected posture, the front wall becomes higher than a rear wall of the rear platform.

5. The pick-up style work vehicle according to claim 1, wherein the forward platform is supported to be slidable in a fore/aft direction along lateral walls of the rearward platform.

6. The pick-up style work vehicle according to claim 5, wherein the forward platform includes a forward bottom which is slidable in association with a sliding movement of the forward platform in the fore/aft direction.

7. The pick-up style work vehicle according to claim 1, wherein a rear end region of the forward platform is supported by a forward end region of the rearward platfonn to be pivotable about a transverse axis.

8. The pick-up style work vehicle according to claim 7, wherein the forward platform includes a forward bottom which is pivotable in association with a pivotal movement of the forward platform about the transverse axis.

9. The pick-up style work vehicle comprising:

a seat section including a forward driver'"'"'s seat and a rear seat, the rear seat including a seat back portion, and seating portion pivotable about an axis extending in a transverse direction of the vehicle;

a rear seat posture changing mechanism for changing the rear seat in its position between a seatable posture where a seating face of the rear seat is oriented upward and an erect posture where the rear seat is pivoted forward from the seatable posture;

a load-carrying platform disposed rearwardly of the seat section, the load-carrying platform including a forward platform and a rearward platform, the load-carrying platform being switchable in its state between an extended state where a fore/aft length of the load-carrying platform is increased after the forward platform being moved forward, and a contracted state where the fore/aft length of the load-carrying platform is decreased after the forward platform being moved rearward; and

a partitioning member for partitioning the seat section from a space behind the seat section, the seat back being disposed in front of the partitioning member and fixed to a front side of the partitioning member;

wherein a lower end portion of the partitioning member approaches the seating portion when the load-carrying platform is switched to the extended state.

10. The pick-up style work vehicle according to claim 9, wherein a lower end portion of the partitioning member is engaged with the seating portion when the load-carrying platform is switched to the extended state.

11. A pick-up style work vehicle comprising:

a rollover protection structure (ROPS);

a seat section including a forward driver'"'"'s seat and a rear seat;

a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in non-use condition and a second posture where the rear seat is in a use condition; and

a partitioning member for partitioning the seat section from a space behind the seat section, the partitioning member being supported by the ROPS;

wherein the ROPS includes right and left posts extending upward and right and left upper frames extending in a fore/aft direction above the seat section;

wherein the partitioning member is movable along the right and left upper frames between a rearwardly displaced position immediately behind the rear seat and a forwardly displaced position moved forward from the rearwardly displaced position; and

wherein the partitioning member is located at the forwardly displaced position when the rear seat is in the first posture, and the partitioning member is located at the rearwardly displaced position when the rear seat is in the second posture.
