Conventionally, in a vehicle seat, the seat back is laid down from the seated posture in which the seat back stands with respect to the seat cushion, and the seat cushion is depressed to the vehicle body floor side in conjunction with the movement of the seat back. There is known a so-called tilt-down mechanism that is moved to a compact position and folded in a compact state.
The configuration of the seat cushion of the vehicle seat is configured such that the seat cushion can be moved between the seating state and the retracted state by a link member pivotally attached between the side portion of the seat cushion and the vehicle body floor side member. ing.

  In such a vehicle seat, for example, another vehicle seat having the same configuration is disposed adjacent to the side of the seat cushion in the rear seat such as the second row. In the configuration in which the vehicle seats are adjacent to each other, a mounting space for a seat belt buckle that constitutes a seat belt device is generally formed at the boundary between both seats in the center of the vehicle. The part is formed in a cut shape. For this reason, the seat belt buckle mounting space has a structure in which a cover made of resin or the like is covered in consideration of poor appearance in which the vehicle body floor side member is exposed.

Irregular ribs 60g are formed on the surfaces of the outer side surface portion 60d and the bottom surface portion 60e.

  As shown in FIG. 6, the object drop prevention tray 60 is disposed and configured between the seat belt buckle connecting portion 42 c and the link member mounting bracket 42 d in the central leg member 42 of the vehicle body floor side member 40. Therefore, as shown in FIG. 4, the position where the object drop prevention tray 60 is disposed is such that the link member 34 is moved when the seat cushion 30 changes its posture from the seat cushion sitting state 30 a to the seat cushion retracted state 30 b. The position includes the moving locus. Therefore, as shown in FIG. 7, the front side surface portion 60c of the object drop prevention tray 60 is formed with a notch portion 60f that allows the link member to enter, so that the link member 34 is allowed to enter. It is configured.

The operation of the vehicle seat anti-drop structure in the present embodiment having the above-described configuration is as follows.
As shown in FIG. 1, in the seated state posture, the object drop prevention tray 60 is disposed in a foreign substance dropping path from a gap forming position formed by the seat belt buckle mounting space 31 to the vehicle body floor F. Therefore, even when a foreign object such as a small object enters, the receiving surface portion 60b blocks the foreign material dropping path, and the small object or the like can be prevented from falling to the vehicle body floor F surface through the gap S.

As shown in FIGS. 2 and 3, when the vehicle seat 10 is not in use, the seat back 20 is stored in the seat back retracted state 20b in a compact posture state, and the back of the seat back 20 is stored. By using the side surface as a loading table for luggage or the like, the space in which the vehicle seat 10 is installed can be emptied into a luggage space L (see FIG. 4).
In this case, when an operation operating force is applied to the operation lever 26 disposed on the shoulder portion of the seat back 20, the operation operating force is transmitted to the reclining mechanism 24 by the wire cable 26a. Then, the operating state of a lock mechanism (not shown) incorporated in the reclining mechanism is switched to switch from a restricting state that restricts relative rotation of the seat back frame 22 to the vehicle body floor side member 40 to a release state that permits the seat back. The posture of the seat 20 is changed from the posture of the seat back seating state 20a to the posture of the seat back storage state 20b.

As illustrated in FIG. 4, the front end portion of the seat cushion 30 sinks to the vehicle rear side in conjunction with the movement of the seat back 20, and the rear end portion of the seat cushion is drawn to the lower end portion side of the seat back. The vehicle is moved to the vehicle rear side and lifted to the vehicle upper side.
This is because the seat cushion pivoting portion 22f (the position at which the seatback mounting bracket 35 of the seat cushion frame 32 is pivotally attached to the lower end portion of the seatback 20) is the rear and lower side of the vehicle as viewed from the center of rotation of the seatback 20. It is pivoted out of position. For this reason, when the seatback 20 falls forward of the vehicle centering around the opening 22e of the lower frame 22b, the seat cushion pivoting portion 22f moves in an arc around the opening 22e of the lower frame 22b. As a result, the rear end of the seat cushion frame 32 moves to the vehicle rear side so as to be drawn to the lower end portion side of the seat back and moves to a posture lifted to the vehicle upper side. As a result, the seat cushion 30 moves into the seat cushion retracted state 30b that is in a substantially horizontal posture and sinks to the vehicle body floor F side.
At this time, the link member 34 enters the receiving surface part 60b from the notch part 60f of the object drop prevention tray 60 in a posture inclined to the vehicle rear side and is stored.

  Thus, according to the object drop prevention structure for the vehicle seat 10 of the first embodiment, the vehicle body through the gap S through the foreign substance drop path from the gap forming position where the foreign substance on the side portion of the seat cushion 30 can drop to the vehicle body floor F is provided. An object drop prevention tray 60 is provided to prevent falling on the floor F surface. The position at which the object drop prevention tray 60 is disposed is a position including a trajectory in which the link member 34 moves when the seat cushion 30 moves between the seat cushion seating state 30a and the seat cushion storage state 30b. Further, the part of the object drop prevention tray 60 arranged on the trajectory along which the link member 34 moves is configured by a configuration unit that allows the link member 34 to enter. Therefore, it is possible to prevent a foreign object such as an accessory from falling without interfering with the link member 34.

  Further, the constituent means that allows the link member 34 to enter is constituted by a cutout portion formed at the location of the object drop prevention tray 60. Thereby, the approach of the link member 34 can be permitted without making the shape of the object drop prevention tray 60 complicated. In addition, concave and convex ribs 60g are formed on the receiving surface portion 60b that receives foreign matter on the object drop prevention tray 60. The strength of the receiving surface portion 60b can be improved by the uneven rib 60g. Moreover, when an accessory etc. fall, rolling can be prevented by this rib 60g.

  Further, the configuration in which the gap S is formed in the side portion of the seat cushion 30 is a configuration in which the gap S is formed by the seat belt buckle mounting space 31 that constitutes the seat belt device 50 provided in the vehicle seat 10. is there. In this configuration, the effect of preventing the falling of objects can be further exhibited. The seat belt buckle mounting space 31 is formed in the vicinity of the vehicle center in the vehicle seat 10. If a foreign object such as a small item falls from this position, it falls to the tire storage section K near the center of the vehicle body floor F. Therefore, since it is a more difficult place to collect foreign objects such as small articles, it is possible to further obtain the effect of preventing falling objects.

The embodiment of the present invention has been described in the first embodiment. However, the vehicle seat drop prevention structure of the present invention is not limited to the present embodiment, and various modifications can be made without changing the gist of the present invention. Can be added and deleted.
For example, in the first embodiment, the vehicle seat 10 having the same configuration is arranged adjacently in the vehicle width direction as the configuration of the vehicle body equipment arranged adjacent to the side of the seat cushion 30. Showed about. However, the present invention is not limited to this, and various body equipment can be applied as long as the body equipment can be equipped on the vehicle. For example, the present invention can be applied to configurations of vehicle doors, vehicle body wall surfaces, console boxes, tire houses, and the like.

  Further, in the first embodiment, as the configuration means that allows the link member 34 to enter the part of the object drop prevention tray 60, the object drop prevention tray in which the notch part 60f is formed is shown. However, the present invention is not limited to this, and the following configuration may be used. 8 and 9 are side views schematically showing Modification Examples 1 and 2 of the object drop prevention tray for the vehicle seat according to the first embodiment. That is, the part where the link member 34 in the part of the object drop prevention tray 60 enters normally constitutes a side surface portion standing on the vehicle front side, and the link member moves to enter the object drop prevention tray. In doing so, a movable side surface portion that allows the link member to enter is constituted by the operating force of the link member. This configuration is shown below.

  FIG. 8 is a side view showing Modification 1 of the object drop prevention tray for vehicle seats. As shown in the figure, for example, in Modification 1, a movable side surface portion 60h that can be opened and closed via a hinge is formed at a position where the link member 34 enters in a portion of the object drop prevention tray 60. . The movable side surface portion 60h normally constitutes a side surface portion standing on the vehicle front side by the urging force of the spring member 60k. When the seat cushion 30 moves from the seat cushion seated state 30a to the seat cushion retracted state 30b, the operating force of the link member 34 resists the urging force of the spring member 60k formed on the movable side surface portion 60h. Defeat 60h. Thus, the link member 34 is configured to enter the object drop prevention tray 60.

  Moreover, FIG. 9 is the side view which showed typically the modification 2 of the fall prevention tray of the vehicle seat. As shown in the drawing, instead of the movable side surface portion 60h configured in the first modification, a movable side surface portion 60j that is slidable in the direction of retreating from the link member 34 is configured. The movable side surface portion 60j normally constitutes a side surface portion erected on the front side of the vehicle by the urging force of the spring member 60m. When the seat cushion 30 moves from the seat cushion seated state 30a to the seat cushion retracted state 30b, the operating force of the link member 34 resists the urging force of the spring member 60m formed on the movable side surface portion 60j. 60j is slid in the direction of retracting from the link member 34. Thus, the link member 34 is configured to enter the object drop prevention tray 60.

  Further, the part of the part of the object drop prevention tray 60 where the link member 34 enters may be a structure in which a cut portion is formed and attached to a plate-like member made of an elastic material. And normally, the side part standingly arranged by the vehicle front side is comprised. When the seat cushion 30 moves from the seat cushion seating state 30a to the seat cushion retracted state 30b, the operating force of the link member 34 is used to enter the object drop prevention tray 60 from the cut portion of the elastic material. There may be.
