Description

  The present invention relates to a vehicle seat that can be flipped up. Specifically, when a sheet that can be moved along a rail can be lifted up only in a specific movement position state, the specific position state can be accurately grasped and aligned. The present invention relates to a vehicle seat.

For vehicle seats such as automobiles, in order to effectively use the space of seats that are not seated as luggage storage, etc., the seat cushion and seat back are folded and the entire seat is flipped up toward the inside of the vehicle interior There is something to do. The seat that flips up and turns in this manner is normally set to a seat on the rear seat side, and is arranged so as to be movable along two rails arranged in parallel.
In this case, the position at which the seat can be flipped up is a specific movement position within the range in which the seat can move, due to the side structure in the vehicle compartment (see Patent Document 1).
In order to grasp the specific movement position that enables the seat to be flipped up, as shown in FIG. 11, a visual recognition mark 90 is given to the side portion 92 of the seat 80 that can be flipped up. ing. As a result, when the tip of the seat cushion 82 of the seat 80 that can be flipped up is the position of the visual recognition mark 90, the specific movement position that can be flipped up is set. In this seat position state, the seat 80 is not attached to the inner rail 86A out of the two rails 86A and 86B arranged on the floor so that the seat 80 can be moved in the longitudinal direction of the vehicle interior. In this state, the sheet 80 can be flipped up and turned. When the seat is flipped up and rotated, the seat back 84 is folded in advance to the seat cushion 82 side, and in this folded state, the outer rail 86B side is set as the center of rotation to the vehicle interior side. It flips up and turns.

  As described above, the specific movement position for the flip-up rotation is adjusted by the visual recognition mark. That is, the sheet shape and visual recognition marks (marks such as arrows) are combined. Such a method of visual matching usually has the disadvantage that it is difficult to align the position, and there is also a problem that the merchantability is lacking.

  The present invention was devised to solve the above-described problems, and the problem to be solved by the present invention is that the seat can be flipped up by giving a sense of moderation when moving on the rail. It is to be able to accurately grasp a specific moving position.

In order to achieve the above object of the present invention, the present invention takes the following means.
In the vehicle seat according to the present invention, first, the seat is attached to the rail so that the seat is movable on two rails arranged in parallel on the floor surface of the vehicle. In a specific movement position state, the seat attachment state to one rail side is released, and the other one rail side is flipped up and turned around the center of rotation. Further, the confirmation means capable of confirming the specific movement position state of the seat that is allowed to be flipped up is a relative relationship between the seat side and the rail side when the seat moves on the two rails. It is a moderation feeling imparting means that can provide a moderation feeling in the specific movement position state during relative movement provided between the moving members.
According to the above-mentioned means of the present invention, when the sheet is moved to the moving position where the sheet can be flipped up, the moderation feeling imparting means can sense the moderation feeling, and the moderation feeling allows the sheet to be flipped up. A specific position can be confirmed, and the flip-up turning operation can be reliably performed in this state.
In addition, when the generation of sound is accompanied with the sense of moderation, the specific movement position where the sheet can be further flipped up and turned can be confirmed.

And the following means can be taken as a preferable moderation giving means in the vehicle seat that can be flipped up according to the present invention.
First, the member constituting the moderation feeling imparting means is a roller whose sheet side rolls on the rail, and the rail side has a step when the roller formed on the rolling surface of the rail on which the roller rolls. It is the structure characterized by being the recessed part which can be felt and moved.
According to this configuration, when the roller on the sheet side rolls on the rail on the rail, if the concave position is reached, a step movement occurs in the rolling of the roller. It can be grasped that it is a specific moving position state that can be moved.

As another configuration, the member constituting the moderation feeling imparting means is a resin moderation imparting piece that slides on the rail surface by applying spring pressure to the rail on the seat side, and the rail side is the moderation degree The moderation imparting piece formed on the sliding surface on which the imparting piece slides is a recess that can move while feeling a step when sliding.
According to this configuration, when the moderation imparting piece on the sheet side slides on the rail on the rail, the stepped movement occurs in the sliding of the moderation imparting piece, so that the seat feels moderate. It is possible to grasp that the seat is in a specific moving position state where the sheet can be flipped up and rotated. In this case, since the moderation imparting piece is made of resin, the sliding resistance is set to a level that does not substantially affect the movement of the sheet.
In addition, the recessed part in each said moderation feeling provision means contains the hole shape penetrated besides the bottomed hole shape with respect to the member in which a recessed part is formed. Further, it is preferable that the bottomed hole shape and the penetrating hole shape are inclined with respect to the moving direction so that the roller or the moderation imparting piece is easy to move. However, as a matter of course, it is necessary to form a concave shape that allows a feeling of moderation when moving. More preferably, the shape is such that sound is produced when a moderation feeling is obtained.

In addition to the moderation feeling imparting means, the vehicular seat according to the present invention is preferably provided with a visual recognition mark similar to the conventional one.
In the case of this configuration, the specific movement position that can be flipped up and turned can be confirmed in advance by visually recognizing with the visual recognition mark, so that the movement of the sheet to the approximate specific movement position is visually recognized. It can be quickly performed in the state, can be accurately grasped by the moderation feeling by the moderation feeling imparting means at the approximate position, and the positioning operation of a specific movement position can be performed speedily.

According to the above-described means of the present invention, the following effects can be obtained.
According to the sheet that can be flipped up according to the present invention, when the sheet is moved to the moving position where the sheet can be flipped up, a feeling of moderation can be felt by the moderation feeling imparting means. The moving operation can be performed reliably and smoothly. When the moderation feeling imparting means is accompanied by the generation of sound along with the moderation feeling, the specific movement position where the sheet can be flipped up and rotated can be confirmed more reliably.

And, when the moderation feeling imparting means is a combination configuration of a roller and a recess, when the roller on the sheet side rolls on the rail on the rail and becomes a recess position, a step movement occurs in the rolling of the roller, A feeling of moderation is felt, and it can be grasped that the seat is in a specific moving position state in which the sheet can be surely flipped up and rotated.
Similarly, when the moderation imparting means is a combination of a moderation imparting piece provided with spring pressure and a recess as the moderation feeling imparting means, the moderation imparting piece provided with the spring pressure on the seat side is not on the rail on the rail side. When the position of the concave portion is reached when sliding, a step movement occurs in the sliding of the moderation imparting piece, a feeling of moderation is felt, and it is in a specific movement position state in which the sheet can be surely flipped up and rotated. I can grasp it.

  Furthermore, in addition to the moderation feeling imparting means, when a configuration in which the same visual recognition mark as the conventional one is applied is given, a specific movement position that can be flipped up is visually confirmed in advance by the visual recognition mark. Therefore, the movement of the seat to the approximate specific movement position can be quickly performed in the visual recognition state, and can be accurately grasped by the sense of moderation by the moderation feeling imparting means at the approximate position. Thus, the positioning operation at a specific moving position can be performed speedily.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

Thus, in a specific position state in which the seat 10 can be flipped up and turned, the seat 10 is detached from the inner slide rail 20 and can be turned up and turned.

Next, each embodiment of moderation imparting means as confirmation means for confirming a specific movement position where the above-described sheet 10 can be flipped up will be described.
A first embodiment is shown in FIG. FIG. 8 is a side view. The moderation imparting means of the first embodiment is configured between the lower rail 22 of the inner slide rail 20 and the roller 26 of the upper rail portion 24 shown in FIG. Specifically, the concave portion 50 is formed in the lower surface portion 22b of the lower rail 22, and the position where the concave portion 50 is formed is the upper rail portion 24 in a moving position where the seat 10 can be flipped up and rotated. This position corresponds to the position where the roller 26 is located. As a result, when the roller 26 rolls on the lower surface portion 22b of the lower rail 22, when the roller 26 rolls in the recess 50, a sense of moderation is obtained and a specific movement that can be swung up and rotated by this moderation sense. It is possible to surely confirm the position. Therefore, the size of the concave portion 50 needs to be a size that creates a step that allows a feeling of moderation when the roller 26 rolls. Further, in order not to impair the original function of the sheet that allows the sheet 10 to move smoothly back and forth, it is also necessary that the roller 26 smoothly rolls on the recess 50 while feeling a step. For this reason, it is preferable that the surface in the rolling direction that forms the recess of the recess 50 is an inclined surface as shown in the figure.

As shown in FIG. 8, the size of the recess 50 in the rolling direction is such that the outer periphery of the roller 26 can contact the bottom surface of the recess 50, so that the roller 26 is placed on the bottom surface of the recess 50. A sound may be produced with a sense of moderation when depressed. Therefore, it is possible to more surely confirm that it is in a specific movement position state that can be flipped up and turned by sound with moderation. In addition, the depth of the groove | channel of the recessed part 50 in this 1st Example shall be about 0.3 mm-0.5 mm. In the illustrated state of FIG. 8, the depth of the groove is slightly exaggerated for easy understanding.
In addition, although the recessed part 50 was shown as a thing with the shape of a hole with a bottom in FIG. 8, the thing of the shape of the hole penetrated may be sufficient. The same applies to each embodiment described below.
In addition, it is preferable that the position on the lower rail where the recessed part 50 is provided is a position where only one of the front and rear rollers 26 provided in the upper rail part 24 passes only once in the moving range in which it moves back and forth. .

  Next, a second embodiment will be described. A second embodiment is shown in FIG. FIG. 9 is a side view. In addition, in each Example shown below including this 2nd Example, the same code | symbol is attached | subjected and shown to the same component as the 1st Example mentioned above. In the case of the second embodiment shown in FIG. 9 as well, the moderation giving means is constituted by a combination of a roller 60 disposed on the sheet 10 side and a recess 50 formed in the lower rail 22. The roller 60 in this embodiment is a dedicated roller provided separately from the roller 26 for moving the sheet 10 back and forth in the case of the first embodiment. The roller 60 is supported by the link 62 and is pivotally supported by the upper rail portion 24. A winding spring 64 is wound around the link 62, and a spring pressure pressing the roller 60 supported by the link 62 against the lower rail 22 is urged. The configuration of the recess 50 formed in the lower rail 22 is the same as that in the first embodiment. As a result, in the case of the second embodiment as well, in the same way as in the case of the first embodiment described above, a specific movement position state that allows the seat 10 to be flipped up by adding a sense of moderation and in some cases a sound. It is possible to grasp with certainty. In particular, in the second embodiment, since a dedicated roller 60 different from the roller 26 for moving the sheet 10 back and forth is used, the operation for moving the sheet 10 back and forth is affected. There are few advantages.

  Next, a third embodiment will be described. A third embodiment is shown in FIG. FIG. 10 is also a side view. The moderation feeling imparting means of the third embodiment shown in FIG. 10 is composed of a combination of a moderation imparting piece 70 disposed on the seat side and a recess 50 formed in the lower rail 22. The moderation imparting piece 70 disposed on the seat side is made of resin in order to reduce sliding resistance, and is attached to a mounting bracket 74 that is integrated with the upper rail portion 24 via a leaf spring 72. Has been supported. The leaf spring 72 urges the moderation imparting piece 70 with a spring pressure that presses against the lower rail 22. The configuration of the recess 50 formed in the lower rail 22 is the same as that in the first embodiment. As a result, in the case of the third embodiment as well, in the same manner as in each of the above-described embodiments, a certain degree of moderation and a specific movement position state that allows the sheet 10 to be flipped up by adding sound in some cases are ensured. Can figure out.

  Next, the flip-up turning operation of the flip-up capable sheet 10 provided with the moderation feeling imparting means of each embodiment will be described. First, the slide lever 16 set at the rear portion of the seat 10 shown in FIG. 2 is released to release the position of the seat 10 relative to the slide rails 20 and 30. As a result, the seat 10 can freely move back and forth. In this state, with the visual recognition mark 40 shown in FIG. A specific sense of movement that can be flipped up can be ascertained with certainty of the sense of moderation by any of the above-described embodiments of the moderation imparting means described above. Then, the sheet 10 can be flipped up and rotated in the order shown in FIG. 1 at the confirmed position.

  In this embodiment, as the means for confirming the specific movement position state in which the sheet 10 is allowed to be flipped up and rotated, the visual mark 40 and the moderation feeling imparting means are used. Since the specific movement position that can be moved can be visually confirmed in advance by the visual recognition mark 40, the sheet can be quickly moved to the approximate specific movement position. And the exact position can be accurately confirmed and grasped by the moderation feeling by the moderation feeling imparting means, and the positioning operation of the specific movement position can be performed quickly. In this case, when it is possible to confirm by sound, the grasp can be performed more easily and reliably.
