  FIG. 7 is an explanatory view showing an example of a conventional retractable seating seat 100. A rubber member 115 is provided on the back side of the seat cushion 101 of the seating seat 100, and when the leg portion 110 of the seating seat 100 is folded, the rubber member 115 comes into contact with the front floor 121, thereby It is supported on the front floor 121.

  At this time, in the conventional seating sheet 100, the rubber member 115 directly contacts the floor. Since the shape of the floor differs depending on the vehicle type, the shape of the rubber member 115 has to be changed according to the floor shape, and there is a problem that the versatility is poor. Further, when the floor shape is different between the stored state and the used state, there is a problem that the seating seat cannot be stably fixed.

  An object of the present invention is to provide a vehicle seat that has a structure that can be stored on a floor, and that can be used for various types of vehicles and has high versatility.

A seating seat for a vehicle having a structure for placing and storing on the front floor, wherein the seat cushion is provided with a seat frame, and a cushioning member is provided on the floor side of the seat frame, and the support Bracket that protrudes to the seat cushion side when the support leg falls to the front floor side Is arranged, the said bracket when storing the rear seat cushioning and the member is solved by abutment.

  As described above, in the seating seat of the vehicle of the present invention, when the seating seat is stored, the cushioning member that supports the seating seat does not directly contact the floor, but contacts the seating seat components. Since the rear end of the seating seat at the time of storage is fixed, the seating seat can be stably fixed without being influenced by the floor shape.

  Further, the bracket is formed with a contact surface that contacts the buffer member when the rear seat is retracted, and a stopper that is substantially perpendicular to the contact surface, and that prevents the support leg from rotating when the rear seat is in use. It is preferable that the surface is formed. If comprised in this way, a buffer member will contact | abut with the contact surface formed in the bracket at the time of storage, and a seating sheet can be fixed stably. In addition, the stopper surface formed on the bracket can prevent further rotation of the support leg when the support leg is raised.

  According to the seating seat for a vehicle of the present invention, when the seating seat is stored, the cushioning member that supports the seating seat does not directly contact the floor, but abuts in the constituent parts of the seating seat and stores. Since the rear end of the seating seat is fixed, it can be stably stored without being influenced by the floor shape. Therefore, it can be employed with high versatility for various types of vehicles.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The members, arrangements, and the like described below are not intended to limit the present invention and can be variously modified within the scope of the gist of the present invention.

That is, the rear seat S as a seating seat of the vehicle of this example is provided with the rear seat S on the rear floor 22 positioned in the upper stage in the vehicle interior, and the front portion of the seat cushion 1 of the rear seat S is attached to the rear seat S so that one end side is rotatable. The other end side is supported by the supporting leg portion 10 fixed to the front floor 21 located at the lower stage, and the rear seat S is moved forward with respect to the vehicle in a state where the seat back 2 of the rear seat S is superimposed on the seat cushion 1. It is provided with a structure that is placed on the front floor 21 and stored by turning it forward.

  As shown in FIGS. 1 and 2, a rear seat S as a seating seat of a vehicle includes a seat cushion 1 having a seating surface, a seat back 2 that can be moved forward with respect to the seat cushion 1, and a seat back 2. The headrest 3 is provided with an upper portion.

  The seat cushion 1 includes a seat frame 1a, support leg portions 10, and cushioning members 14 and 15 made of a rubber material, a resin material, or the like. A pair of left and right support legs 10 that support the front portion of the seat cushion 1 when the rear seat S is in use are provided on the lower surface of the seat frame 1a of the present example on the vehicle front side. A rear seat S is rotatably installed between the front floor 21 and the rear floor 22 via the support leg 10.

  The rear seat S will be described in more detail with reference to FIGS. The support leg portion 10 of this example includes a support leg 11, a fixing portion 12, and a bracket 13. An attachment hole 12b is formed in the fixed portion 12, and the fixed portion 12 is fixed to the front floor 21 by an anchor bolt or the like passing through the attachment hole 12b. The end of the support leg 11 on the seat frame 1a side is pivotally supported by a shaft member 16a as a support shaft via a side member 1b disposed on the seat frame 1a by welding or the like. Further, the end of the support leg 11 on the floor side is pivotally supported by the fixed portion 12 so as to be rotatable about the shaft member 16b.

  In addition, cushioning members 14 are disposed on the floor side surface of the seat frame 1a with a gap therebetween. The buffer member 14 is disposed between the side members 1b in the vicinity of the support shaft of the support leg 10. In this example, the left and right shock-absorbing members 14 are formed to have different shapes in accordance with the shape of the front floor 21. In addition, when the floor shape which the right and left buffer members 14 contact is the same, the buffer members 14 are formed in the same size. Further, as will be described later, the buffer member 14 includes a rotation preventing surface 14 a that contacts the support leg 11 and a floor contact surface 14 b that contacts the front floor 21. The floor contact surface 14b is formed so as to be substantially parallel to the front floor 21, and the rotation preventing surface 14a is formed so as to form an angle of approximately 90 ° with the floor contact surface 14b.

The bracket 13 of this example is fixed to the support leg 11 by welding or the like. As shown in FIG. 6, the bracket 13 is fixed so as to be positioned on a shaft member 16 b that rotatably connects the support leg 11 and the fixing portion 12.
The bracket 13 includes a contact surface 13a that faces the seat cushion 1 when the support leg 11 falls to the front floor 21 side, and a rotation prevention formed on the fixed portion 12 when the support leg 11 is raised. A stopper surface 13b that abuts against the surface 12a and prevents further rotation of the support leg 11 is formed. The bracket 13 of this example is configured to rotate together with the support legs 11. In this example, the portion of the bracket 13 having a function of contacting the buffer member 15 may be formed on the fixed portion 12 instead of the support leg 11.

  As shown in FIG. 5, the buffer member 15 includes a buffer main body 15a and a mounting portion 15b protruding from the buffer main body 15a. The mounting portion 15b is formed in a hollow cylindrical shape, and is formed on the free end side. The flange 15c is formed with a gap in the thickness of the seat frame. The buffer body 15a is substantially cylindrical and has a flat surface 15d. The buffer member 15 corresponds to the buffer member in the claims. In this example, a pair of cushioning members 15 are provided on the left and right sides in the width direction of the seat. When the flange portion 15c and the attachment portion 15b are press-fitted into the holes drilled in the seat frame 1a, the seat frame 1a is sandwiched between the flange portion 15c and the buffer body 15a, whereby the buffer member 15 can be attached to and detached from the seat frame 1a. Mounted on.

As described above, in the rear seat S of this example, the rear seat S can be switched between the storage state shown in FIG. 1 and the use state shown in FIG. 2 by rotating the support leg 11.
FIG. 1 shows a state in which the rear seat S is stored on the front floor 21. The rear seat S is stored with the seat cushion 1 positioned on the front floor 21 by tilting the support legs 11 toward the front floor 21. At this time, the seat back 2 is moved forward to the seat cushion 1 side. The rear seat S is supported by the buffer member 14 and the buffer member 15 in the retracted state.
That is, the floor contact surface 14b of the buffer member 14 contacts the front floor 21 to support the rear seat S, and the surface 15d of the buffer member 15 contacts the contact surface 13a of the bracket 13 to support the rear seat S.

  Thus, when the rear seat S is stored, the buffer member 15 that supports the rear seat S does not directly contact the floor, but contacts the bracket 13 that is a component of the rear seat S, and the rear seat S during storage is stored. Since the rear end is fixed, the rear seat S can be stably fixed without being influenced by the floor shape.

FIG. 2 shows the usage state of the rear seat S. In the rear seat S, the seat cushion 1 is positioned above the front floor 21 by raising the support legs 11.
The support leg 11 abuts against the rotation preventing surface 14a of the buffer member 14 and is prevented from moving so as not to be further rotated. Further, the stopper surface 13 b of the bracket 13 fixed to the support leg 11 is engaged with the rotation preventing surface 12 a of the fixing portion 12, so that the support leg 11 is prevented from rotating.

  A lock member 17 a provided on the rear end side of the seat cushion 1 meshes with a striker 17 b provided on the rear floor 22. Then, the seat back 2 and the headrest 3 are raised with respect to the seat cushion 1. In this way, the rear seat S is in use.
