, It is difficult to see from the worker M,
When the folded rear sheet 100 is pulled as indicated by an arrow c2 and the hook 105 hits the hook stopper 104, there is a possibility that the hook 105 may be erroneously recognized as being hooked on the hook stopper 104. Also, as shown in the above (d), considering that the work is performed in a vehicle (not shown), when the hook 105 is hooked on the hook stopper member 104, the folded rear seat 100 is moved in the direction indicated by the arrow d. Lifting work is difficult as described above, and it is desired to hook the hook 105 on the hook stopper 104 without performing the lifting operation of the rear seat 100.

Accordingly, an object of the present invention is to provide a vehicle seat that can securely stop a seat on the floor side and can easily stop the seat on the floor side.

[0005]

In order to achieve the above object, a first aspect of the present invention is to provide a link between a floor and a seat frame, and to separate a hook on a seat frame side from a locking means on the floor side, and then a link. In the vehicle seat that can be moved from the use state to the storage state or vice versa by the guidance of the above, a step portion formed one step higher on the floor is formed, and
When returning the vehicle seat from the storage state to the use state in the part, the lower end of the hook substantially matches the upper surface height of the locking means
To form a slope that is inclined upward toward the rear.
A recess is formed at the back of the surface to accommodate the hook,
Form a hook stopper on the slope to reduce sliding friction on the slope
The sliding member is covered .

When the vehicle seat is returned from the stored state to the use state, the lower end of the hook is pulled up to the position before the locking means while sliding the lower end of the hook on the sloped sliding member provided at the step portion, and further pulled backward to pull the vehicle seat. Is lowered by its own weight so that the hook is hooked on the locking means. When the hook is hooked on the locking means, there is no need to perform an operation of lifting and lowering the vehicle seat, so that the hook can be easily hooked on the locking means. Further, since only the operation of pulling the vehicle seat backward is performed, the hook can be reliably hooked on the locking means.
