Are connected. The wire 22 has an upper end connected to the center of the swing link 21 and a lower end connected to the end of the arm 4A. The transmission mechanism 20 configured as described above performs an operation of pulling out the drawer band 11 from the inside of the seat back 2, whereby the swing link 21 is pulled by this and rotates counterclockwise with the left end portion in the drawing as the base end. Is operated. As a result, as shown in FIG. 7, the wire 22 is pulled upward in the drawing, and the arm 4A is rotated counterclockwise. The rod 4R is pivoted by the pivoting operation of the arm 4A, and the locked state of each reclining device 4 is released.

  Here, the rod 4 </ b> R is normally held at a rotational position where each reclining device 4 is in a lock operating state by a biasing force of a biasing spring (not shown) provided between the rod 4 </ b> R and the reclining device 4. The rod 4 </ b> R is rotated against the urging force of the urging spring by the operation of pulling out the drawer band 11, and is rotated to a position where the reclining device 4 is unlocked. The rod 4R is returned to the rotational position where each reclining device 4 is returned to the locked state by the action of the urging force by stopping the operation of pulling out the drawer band 11. As a result, the drawer band 11 is always held in a state in which it is drawn into the shape of the seat back 2 until the rod 4R is returned to the original rotation position by the action of the urging force before the drawer operation is performed. It has come to be. Here, the structure which urges | pulls the drawer band 11 in the direction which draws in the inside of the shape of the seat back 2 corresponds to the urging means of this invention.

Next, returning to FIG. 3, the fixed band 13 is formed to have a shorter band length than the drawer band 11, and from the inside of the shape of the seat back 2 to the back surface 2 </ b> B side at a middle position in the vertical direction of the seat back 2. It is provided in the form of being pulled out. The end of the fixed band 13 drawn out from the inside of the shape of the seat back 2 is integrally coupled to the lower end of the grip 12. Specifically, as shown in FIG. 4, the fixing band 13 is pulled out from the outlet Dh of the bezel 2 </ b> D made of a resin material fixed to the back surface 2 </ b> B of the seat back 2.
Returning to FIG. 3, the end of the fixed band 13 that is drawn into the shape of the seat back 2 is integrally fixed to the back panel 2 </ b> P that forms the skeleton of the seat back 2. The fixed band 13 is configured as a connecting member that connects the lower end of the grip 12 and the back surface 2B of the seat back 2.

Next, as shown in FIG. 3, the grip 12 is configured as a grip operation unit that grips the operation member 10 for pulling operation. The grip 12 is thicker than the drawer band 11 and the fixed band 13 and is relatively bent. The structure is easy to grip with increased rigidity. The grip 12 is disposed such that the longitudinal direction of the elongated shape extends in the vertical direction (longitudinal direction) along the back surface 2 </ b> B of the seat back 2. Specifically, the grip 12 is disposed so as to extend in the vertical direction across the intermediate position in the vertical direction of the seat back 2. This makes it easy for a tall operator or a short operator to touch the grip 12 from the rear side of the seat 1.
As described above, the upper end and the lower end of the grip 12 are coupled to the end of the pull-out band 11 and the end of the fixed band 13 which are pulled out from the back of the seat back 2. Therefore, the grip 12 always comes into contact with the back surface 2B of the seat back 2 by the action of the urging force by which the drawer band 11 is pulled into the shape of the seat back 2 before the pulling operation. It is in a state. Specifically, as shown in FIG. 4, the grip 12 is placed on the seating surfaces Us and Ds in a state where the upper end and lower end thereof are housed in the frame portions Uf and Df of the bezels 2U and 2D, respectively. They are in contact. As a result, the entire operation member 10 including the grip 12 is held in a state in which there is little protrusion to the back surface 2B side of the seat back 2.
Here, returning to FIG. 3, the back surface 2 </ b> B of the seat back 2 is formed with a resilient force and is configured to be compressible and deformable in the thickness direction. Specifically, the back surface 2B of the seat back 2 is configured such that a soft cover member such as a jersey is covered with a surface layer of a soft cushion pad made of a urethane resin foam.

On the other hand, the surface of the grip 12 on the side in contact with the back surface 2B of the seat back 2 is repeatedly formed with uneven shapes (convex portions 12A and concave portions 12B) along its longitudinal direction. As shown in FIG. 7, these convex portions 12A and concave portions 12B function as anti-slip to prevent the fingers F from slipping in the longitudinal direction when the operator's fingers F are put on the grip 12 and pulled. To do. As shown in FIG. 3, the grip 12 having such an uneven shape presses the grip 12 when it comes into contact with the back surface 2 </ b> B of the seat back 2, and slightly deflects and deforms it. Thereby, since the clearance gap S accompanying the said bending deformation is formed between the grip 12 and the back surface 2B, it becomes easy to put the operator's finger F in between.
Further, as shown in FIG. 5, the operator's finger F can be smoothly inserted between the grip 12 and the back surface 2 </ b> B of the seat back 2 on the surface of the grip 12 that contacts the back surface 2 </ b> B of the seat back 2. A round shape (guide surface 12C) is formed. This guide surface 12C is formed so as to round between the surface portion of the grip 12 that comes into contact with the back surface 2B of the seat back 2 and the surface portion into which the operator's finger F is inserted.
Therefore, in order to put the operator's finger F between the grip 12 and the back surface 2B of the seat back 2, the back surface 2B of the seat back 2 is compressed following the guide surface 12C formed in the grip operation portion. The insertion operation can be easily performed by inserting the finger F so as to deform (see FIG. 6).
Then, as shown in FIG. 7, the grip 12 is pulled by operating the pulling portion of the fixed band 13 connecting the lower end portion and the back surface 2B of the seat back 2 to the front as a fulcrum. The Thereby, the drawer band 11 can be pulled out from the inside of the shape of the seat back 2 and an operation of releasing the locked state of the reclining device 4 can be performed.

Subsequently, a method of using the present embodiment will be described.
That is, as shown in FIG. 1, the seat 1 is operated by pulling the grip 12 of the operation member 10 provided on the back surface 2 </ b> B of the seat back 2 and pulling it down toward the front, whereby each reclining device 4. The locked state of is released. Thereby, since the seat back 2 is automatically moved forward, the seat 1 can be in a folded posture state.
In addition, in order to return the folded seat 1 to the original seatable posture state, the hand is extended to the grip 12 of the operation member 10 on the back surface 2B of the seat back 2 in the forwardly tilted position. The pulling operation may be performed in the same manner as described above. Thereby, the locked state of each reclining device 4 can be cancelled | released. If the seat back 2 is raised by pulling the grip 12 as it is, the seat 1 can be returned to the original seatable posture. Here, each reclining device 4 is configured to maintain the unlocked state until the forwardly retracted seat back 2 is raised to a certain position. Therefore, when the seat back 2 is raised, the seat back 2 is raised only by the pulling operation of the grip 12 up to a position where the hand can reach the seat back 2, and the hand reaches the seat back 2. After that, the seat back 2 can be lifted directly by hand.

As described above, according to the vehicle seat operation member disposition structure of the present embodiment, the operation member 10 is disposed so as to extend in the vertical direction along the back surface 2B of the seat back 2, and is normally used as the seat back. 2 is held in contact with the back surface 2B so as not to project to the back surface 2B side, and a guide shape (guide surface 12C) is provided on the grip 12 so that the operator's finger F can be easily inserted. With the configuration in which 2B is easily bent, the operation member 10 disposed on the seat 1 can be disposed on the back surface 2B side of the seat back 2 so that it looks good and can be easily operated.
Further, since the grip 12 is formed of a flexible rubber material, the grip 12 itself is also bent and deformed when the finger F is put between the grip 12 and the back surface 2B of the seat back 2, so that such an operation is performed. It can be done more easily.
Furthermore, the grip 12 is disposed so as to extend in the vertical direction across the middle position in the vertical direction of the seat back 2, so that the operator can control the grip 12 regardless of whether the operator is tall or low. It is possible to easily perform the operation of pulling by applying. Furthermore, since the guide shape formed on the grip 12 is a round shape, the operator's finger F can be easily inserted between the back surface 2B of the seat back 2. Furthermore, since the operator's finger F hung on the grip 12 can be prevented from slipping in the longitudinal direction due to the uneven shape formed on the grip 12, the operation member 10 can be easily pulled. Furthermore, since the grip 12 can be pulled and pulled to the front, the grip 12 can be pulled easily from the rear side of the seat 1.

Then, the operation member arrangement structure of the vehicle seat of Example 2 is demonstrated using FIG. In the following description, explanations are omitted for the parts that exhibit substantially the same configuration and operation as the vehicle seat operating member arrangement structure described in the first embodiment, and different reference numerals are given to different parts. Explain in detail.
In the present embodiment, a fitting structure is formed between the grip 12 and the bezel 2U in which the upper end of the grip 12 is accommodated. Specifically, protrusions 12D projecting outward are formed on both sides of the grip 12, and these protrusions 12D are fitted into fitting grooves fv formed on both inner sides of the frame part Uf of the bezel 2U. It has become. Thereby, it can hold | maintain in the state which is not rattling as the state which made the grip 12 contact the back surface 2B of the seat back 2. FIG.

Although the embodiment of the present invention has been described with reference to two examples, the present invention can be implemented in various forms in addition to the above-described example.
For example, the grip as the grip operation unit may be formed of a hard material such as a resin material in addition to that formed of a rubber material. In this case, when the operator's finger is hooked on the grip, the grip is not bent and deformed, but the operation of hooking the finger can be easily performed by the guide shape of the grip or the bending deformation of the seat back.
Moreover, although what showed the grip extended in the up-down direction across the intermediate position of the up-down direction of the seat back was shown, you may arrange | position without extending over the intermediate position. However, in this case, for example, when the grip is disposed above the middle position in the vertical direction, the pulling operation is easy for a tall operator, but for a short operator, the pulling operation is easy. Operation becomes difficult. In addition, when the grip is disposed below the intermediate position in the vertical direction, the pulling operation is easy for a short operator, but the pulling operation is difficult for a tall operator. .
Moreover, it is good also as a structure which reversed the up-and-down arrangement | positioning relationship of a fixed band and a drawer band. In other words, the grip may be operated so as to be pulled up with the pull-out portion of the fixed band connecting the upper end of the grip and the back of the seat back.
In addition to the round shape, the guide shape formed on the grip can be formed by a slope shape or a step shape. Moreover, the uneven | corrugated shape formed side by side in the longitudinal direction of the grip shown in the said Example can also be applied as a guide shape. That is, it is possible to obtain a configuration that guides the operator's finger so that the operator's finger can be smoothly inserted by the recessed portion that is recessed with respect to the back surface of the seat back.
