DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 is a rear seat composed of a seat cushion 11 and a seat back 12, 2 is a headrest attached to the seat back 12, and 3 is a hinge fitting for pivotally supporting the seat back 12 on the vehicle floor 4 as described above. The vehicle floor 4 is formed by forming a rear floor surface 43 that is one step higher than the front floor surface 41 through a standing wall 42 at the rear end of the front floor surface 41. The rear floor surface 43 is provided with a front seat cushion. A surface 44 and a rear cargo room surface 45 that is one step higher than the surface 44 are formed. Then, the seat cushion 11 of the rear seat 1 is disposed on the rear floor surface 43 to be used as a rear seat so that the above-described seat cushion 11 can be stored on the front floor surface 41 when it is desired to expand the cargo space. The above configuration is basically the same as that of a conventional vehicle rear seat of this type.
Reference numeral 5 denotes an L-shaped link 5 unique to the present invention. The L-shaped link 5 allows the seat cushion 11 to be mounted on the seat cushion installation surface 44 of the rear floor surface 43 and the front floor. It is possible to switch between two modes: the storage state moved to the surface 41. That is, the L-shaped link 5 is arranged along the upper half of the standing wall 42 from the front half of the rear floor surface 43, and one end of the L-shaped link 5 is arranged substantially in the middle of the standing wall 42. One end is pivotally attached to the position, and the other end is pivotally attached to the lower surface of the seat cushion 11 mounted on the rear floor surface 43. When it is desired to expand the cargo space, the L-shaped link 5 allows the seat cushion 11 to be moved and stored on the front floor surface 41. The seat cushion 11 can be stored in a state of being completely buried immediately before the standing wall surface of the front floor surface 41, and the operation of expanding the cargo space can be easily performed without the need to remove the headrest 2 as in the prior art. Can be performed.
[0008]
As shown in FIGS. 1 to 2, the L-shaped link 5 described above can be rotated 180 degrees at one end to a substantially intermediate position of the standing wall 42 at the front end of the rear floor surface 43 via the hinge brackets 7, 7. The portion below the middle bent portion is pivoted along the upper half of the standing wall 42, and the portion above the bent portion of the L-shaped link 5 is the front half of the rear floor surface 43. The other end of the L-shaped link 5, that is, the tip of the portion above the bent portion, can be rotated 180 degrees through the brackets 8, 8 to the middle position of the panel 10 on the lower surface of the seat cushion. It is pivotally attached. As described above, one end of the L-shaped link 5 is pivotally attached to the substantially intermediate position of the standing wall surface 42, and the other end is pivotally attached to the substantially intermediate position of the lower surface of the seat cushion 11 mounted on the rear floor surface 43. Thus, since the turning radius of the L-shaped link 5 when the seat cushion 11 is stored in the front floor surface 41 lower than the rear floor surface 43 can be shortened, a compact design can be achieved.
[0009]
As shown in FIG. 1, the construction of the rear seat 1 is normally used as a seat and is used for the seat, and is arranged on the rear floor surface 43 as necessary. The point that the seat cushion 11 is stored in the front floor surface 41 to expand the cargo space is basically the same as that of this type of conventional vehicle rear seat, but in the present invention, it is one step lower than the rear floor surface 43. The rear floor surface is higher than the front floor surface 41 by an L-shaped link 5 having one end pivotally attached to a substantially middle position of the vertical wall surface 42 following the rear end of the front floor surface 41. 43, the other end is pivotally attached to the substantially middle position of the lower surface of the seat cushion 11 mounted on the rear floor surface 43. When the seat cushion 11 is pulled to the front side, first, the seat Cushion 11 rotates through the L-shaped link 5 and smoothly moves to the front floor surface 41 up to the position shown by the solid line in FIG. 5, and immediately before the standing wall surface of the front floor surface 41 shown by the solid line in FIG. Move to the position without flipping. Since the L-shaped link 5 fits snugly along the lower front floor surface 41 and the standing wall surface 42 after the rotation, the seat cushion 11 has a lower surface intermediate position pivotally attached to the other end of the L-shaped link 5. Is completely stored along the front floor surface 41 that is one step lower than the rear floor surface 43. Furthermore, since the L-shaped link 5 has a short turning radius, the width of the low front floor surface 41 can be reduced and a compact design can be achieved, and the front seat can be used with the front seat fully retracted, thereby obtaining excellent usability. Can do.
[0010]
Further, after the seat cushion 11 is moved and stored on the front floor surface 41, as shown in FIG. 4, the rear luggage compartment surface 45 formed one step higher than the seat cushion installation surface 44 of the rear floor surface 43. If the seat back 12 erected along the front surface of the vehicle is stored on the rear floor surface 43 in a forward-turned state in which the back surface is substantially flush with the cargo room surface 45, the cargo space can be expanded. Well, in this case, since the seat cushion 11 can be completely stored on the lower front floor surface 41 as described above, the seat back 12 can be moved forward without removing the headrest 2, and the luggage space can be expanded by a simple operation. Become.
[0011]
As shown in FIG. 5, depending on the application, the seat cushion 11 pulled toward the front floor surface 41 can be stopped in a vertical state to enlarge the cargo space. In this case, the front floor can be expanded. It is also possible to stably store a tall luggage stored on the surface 41 as being supported by the seat cushion 11.
[0012]
【The invention's effect】
As is clear from the above description, the seat cushion of the rear seat on the rear floor surface is moved and stored on the front floor surface, which is one step lower than the rear floor surface, by a simple operation. There is an advantage that the seat back can be moved forward while the headrest is still attached.
Therefore, the present invention contributes greatly to industrial development as a vehicular rear seat that eliminates the conventional problems.
