Description

  The present invention relates to an underfloor storage device installed in a vehicle such as an automobile, an airplane, a ship, a train, or a facility such as a movie theater.

  Some vehicles have a storage space on the floor behind the seat for seating (see Patent Document 1). In some cases, the seat for seating is slidable on the floor including the storage space.

JP 2004-268757 A

  When the seat for seating is movable on the storage space, depending on the structure, the slide rail is positioned on the storage space and straddles the opening of the storage space. For this reason, the opening of the storage space cannot be used widely, and it becomes difficult to store a large article.

  An object of the present invention is to enable a seating seat to be slidable on a floor including the storage space, and when the seating seat moves away from the storage space on the slide rail straddling the storage space, Move away from the storage space with the seat. Thereby, in a state where the seat for seating leaves the storage space, the slide rail does not exist on the storage space.

  1st invention is an underfloor storage apparatus provided with the seat for sheet | seats provided with the storage space of the articles | goods formed by digging down the floor partially, and being made to be slidable on the floor including the said storage space with a slide rail . The slide rail is provided so as to be slidable on the fixed rail by fixing the fixed rail installed on the floor without straddling the storage space, and the seat for the seat. A movable rail which is movable between a first position on the storage space and a second position on the floor away from the storage space together with the seat.

  In the first invention, the storage space may be used for storing the seat for seating, or may be used for storing other articles. The fixed rails are not limited to those that are all located on the floor and do not protrude at all in the storage space, but may be those in which a part of the fixed rail protrudes into the storage space.

  According to the first invention, the movable rail is slid and moved together with the seat for seating between the first position on the storage space and the second position on the floor. Therefore, when the seat for seating is in the second position, the movable rail of the slide rail does not exist in the storage space. On the other hand, the fixed rail is provided on the floor without straddling the storage space. As a result, the slide rail does not narrow the entrance of the storage space, and articles can be easily put in and out of the storage space.

  According to a second invention, in the first invention, the slide rail is provided on the first slide rail fixed on the floor without straddling the storage space, and further on the first slide rail. And a second slide rail on which the seat for seating is mounted. Each of the first and second slide rails includes a lower rail and an upper rail combined so as to be relatively slidable. The fixed rail is configured by a first lower rail which is a lower rail of the first slide rail, and the movable rail is a first upper rail which is an upper rail of the first slide rail, and the first rail fixed to the first upper rail. The second lower rail, which is the lower rail of the two slide rails, and the second upper rail, which is the upper rail of the second slide rail.

  According to the second invention, the movable rail can be moved in multiple stages by the first upper rail, the second lower rail, and the second upper rail. Therefore, a large amount of movement of the movable rail on the storage space can be secured while the length of the slide rail is restricted, and the slide rail can be installed in a large storage space.

  According to a third invention, in the first invention, between the slide moving tip of the movable rail and a corresponding portion on the floor corresponding to the slide moving tip in a state where the movable rail is in the first position. And a coupling mechanism that selectively and mechanically couples between the slide moving tip and the corresponding portion.

  According to the third aspect of the invention, it is possible to couple the slide moving tip of the movable rail and the corresponding portion on the floor by the coupling mechanism in a state where the movable rail is at the first position. Therefore, the movable rail and the seat for seating in the first position can be stably supported.

  In a fourth aspect based on the second aspect, the lower portion of the seat for seating is rotated in the vertical direction with respect to the storage space side end of the second upper rail in a state where the second upper rail is in the second position. A hinge mechanism that can be freely coupled is provided. The hinge mechanism is capable of storing the seating seat in the storage space by rotating the seating seat around the storage space side end in a state where the movable rail and the seating seat are in the second position. It is configured.

  According to the fourth invention, when the movable rail and the seat for seating are in the second position, the seating seat is rotated by the hinge mechanism around the storage space side end of the second upper rail into the storage space. Can be stored. Therefore, an underfloor storage sheet can be realized using the storage space.

It is a side view of one embodiment of the present invention, and shows the state where a sheet is in the 1st position. FIG. 2 is a side view similar to FIG. 1, showing a state where the sheet is in the second position. FIG. 2 is a side view similar to FIG. 1 and shows a state in which a sheet is stored. FIG. 3 is a plan view of FIGS. 1 and 2. It is an enlarged view of the V section of FIG.

  1 to 4 show an embodiment of the present invention. This embodiment shows an example in which a third-row seating seat (hereinafter simply referred to as a seat) 10 can be stored under the floor 1 in an automobile having a three-row seat. In each figure, the direction of each part in the state which mounted the sheet | seat in the motor vehicle by the arrow is shown. In the following description, the description regarding the direction is made based on this direction.

  The seat 10 includes a seat back 11 that forms a backrest and a seat cushion 12 that forms a seat portion, and a headrest 13 that supports the head of the seated person from behind at the upper end of the seat back 11. The seat back 11 can be moved forward with respect to the seat cushion 12 by a recliner 16. Two seats 10 are arranged side by side on the left and right.

  As shown in FIGS. 1, 2, and 4, the floor 1 at the rear of the vehicle body 3 is formed with a storage space 2 having a size capable of storing two seats 10 side by side by digging down partially. On the floor 1 in front of the storage space 2, slide rails 20 that are paired on the left and right of each seat 10 are fixed. Here, the slide rail 20 is disposed without straddling the storage space 2. The seat 10 is slidable in the front-rear direction along the slide rail 20. When the seat 10 is moved rearward by the maximum amount, the seat 10 is positioned on the storage space 2 (on the right side in FIGS. 1 and 4). Sheet 10). This position is referred to as a first position. When the maximum amount is moved forward, the seat 10 moves forward from the storage space 2 and is positioned on the floor 1 (see the left seat 10 in FIGS. 2 and 4). This position is referred to as a second position.

  As shown in FIGS. 1 to 4, each slide rail 20 includes a first slide rail 21 and a second slide rail 22 having substantially the same structure in two upper and lower stages. Each of the first slide rail 21 and the second slide rail 22 has a known structure, and includes a combination of a lower rail and an upper rail that are slidable in the front-rear direction. The first lower rail 21 a which is the lower rail of the first slide rail 21 is fixed on the floor 1 without straddling the storage space 2. The first upper rail 21b that is the upper rail of the first slide rail 21 is integrally coupled to the second lower rail 22a that is the lower rail of the second slide rail 22 by a rivet (not shown). The second upper rail 22 b that is the upper rail of the second slide rail 22 is fixed to the lower portion of the seat cushion 12 via the lock mechanism 14 and the hinge mechanism 15. Here, the first lower rail 21a corresponds to the fixed rail in the present invention, and the first upper rail 21b, the second lower rail 22a, and the second upper rail 22b correspond to the movable rail in the present invention.

  The lock mechanism 14 connects the front end portion of the seat cushion 12 and the front end portion of the second upper rail 22b in a state where the lock mechanism 14 is coupled to the striker 22c provided on the second upper rail 22b. Further, the hinge mechanism 15 connects the rear end portion of the seat cushion 12 and the rear end portion (storage space side end portion) of the second upper rail 22b so as to be rotatable in the vertical direction.

  FIG. 1 shows that the first upper rail 21b of the first slide rail 21 is at the rear maximum position (rearmost) RM with respect to the first lower rail 21a, and the second upper rail 22b of the second slide rail 22 is relative to the second lower rail 22a. And the rear maximum position (rearmost) RM. In this state, the seat 10 is positioned on the storage space 2 to ensure a large front space of the seat 10.

  In this case, the slide rail 20 is composed of first and second slide rails 21 and 22, and the length of the second lower rail 22 a is relatively short with respect to the length straddling the storage space 2. That is, when the slide rail 20 is constituted by a combination of one lower rail and one upper rail, the lower rail is fixed at a position on the floor 1 that does not straddle the storage space 2, and the upper rail that fixes the seat 10 is fixed to the lower rail. It is necessary to make it slidable and to have a length straddling the storage space 2. In that case, the length of the slide rail 20 in the slide direction must be long. On the other hand, when the slide rail 20 is configured by combining the two slide rails 21 and 22 as in the present embodiment, the second lower rail 22a is supported by the first upper rail 21b. Can be shortened, and the length of the second lower rail 22a can be shortened. Therefore, the slide direction length of the slide rail 20 can be shortened. Therefore, this embodiment can be implemented even when the slide direction length of the slide rail 20 is restricted.

  2, the first upper rail 21b of the first slide rail 21 moves from the state of FIG. 1 to the maximum front position (front most) FM with respect to the first lower rail 21a, and the second upper rail 22b of the second slide rail 22 is moved. Shows a state in which the second lower rail 22a has moved to the front maximum position (frontmost) FM. In this state, the seat 10 moves to the front of the storage space 2 and is positioned on the floor 1. At this time, the entire slide rail 20 is positioned on the floor 1 without straddling the storage space 2. As a result, the slide rail 20 does not exist above the storage space 2, and the front of the storage space 2 can be widened to store large articles.

  FIG. 3 shows a state in which the sheet 10 is stored in the storage space 2 from the state of FIG. As shown by the arrows, the seat 10 is stored by rotating the seat 10 around the connection point between the hinge mechanism 15 and the second upper rail 22b. At that time, the seat back 11 is folded on the seat cushion 12 around the recliner 16, and the lock mechanism 14 is separated from the striker 22c. The lock mechanism 14 is separated from the striker 22c, and when the seat 10 is rotated and stored, the lock mechanism 14 receives the rotation operation and is folded along the lower surface of the seat cushion 12 as shown by the solid line in FIG. . FIG. 4 shows a state in which the sheet 10 is stored in the storage space 2 with a virtual line. The storing operation of the sheet 10 is performed by motor driving or manually.

  Although not shown, each of the first slide rail 21 and the second slide rail 22 includes a lock mechanism inside. Such a locking mechanism selectively performs sliding movement between the first lower rail 21a and the first upper rail 21b of the first slide rail 21 and between the second lower rail 22a and the second upper rail 22b of the second slide rail 22. Lock it. Each locking mechanism of the first slide rail 21 and the second slide rail 22 locks the slide movement at the positions of the above-mentioned rear most RM and front most FM, and arbitrarily slides even at the slide position between these positions. Lock it.

  As shown in FIG. 1, in a state where the second slide rail 22 is at the position of the rear most RM, the lock mechanism can be locked at a slide position where the second lower rail 22a protrudes rearward from the second upper rail 22b. On the other hand, as shown in FIGS. 2 and 3, when the second slide rail 22 is in the position of the front most FM, the second upper rail 22 b and the hinge mechanism 15 are in the slide position protruding rearward from the second lower rail 22 a. Can be locked. In other words, in a state where the second slide rail 22 is at the position of the rear most RM, the second upper rail 22b is configured not to move to a slide position protruding rearward from the second lower rail 22a. Further, in a state where the second slide rail 22 is in the position of the front most FM, the second lower rail 22a is configured not to move to a slide position protruding rearward from the second upper rail 22b.

  As shown in FIGS. 1, 4, and 5, a U-shaped striker 31 is provided to project rearward from the rear end portion (sliding movement tip portion) of the second lower rail 22 a in a plan view. Further, in a state where the seat 10 and the second slide rail 22 are in the position of the rear most RM, a lock mechanism 32 is provided at a corresponding portion of the floor 1 corresponding to the rear end portion of the second lower rail 22a. The lock mechanism 32 is configured to receive the striker 31 so as to face the striker 31. The striker 31 and the lock mechanism 32 constitute a coupling mechanism 30, and the striker 31 is gripped by the lock mechanism 32 and the second lower rail 22 a moves forward in a state where the second slide rail 22 is at the position of the rear most RM. It is locked so as not to.

  The position of the lock mechanism 32 on the floor 1 is set behind the stepped portion 1a formed to receive the rear end portion of the second lower rail 22a behind the storage space 2. Therefore, when the second slide rail 22 is in the position of the rear most RM and the second lower rail 22a is locked by the coupling mechanism 30, the rear end of the second lower rail 22a is placed on the stepped portion 1a, and the seat 10 is It can be stably supported on the storage space 2.

  As mentioned above, although specific embodiment was described, this invention is not limited to those external appearances and structures, A various change, addition, and deletion are possible in the range which does not change the summary of this invention. For example, in the above-described embodiment, the present invention is applied to the third row seat of an automobile. However, the present invention may be applied to a first row, a second row seat, a seat mounted on an airplane, a ship, a train, or the like, or You may apply to the seat for seating installed in facilities, such as a movie theater. Further, the direction of the seat slide movement is not limited to the front-rear direction. You may be made into the left-right direction and the diagonal direction. Furthermore, in the said embodiment, although comprised so that a sheet | seat might be stored in storage space, you may make it store only various articles, without storing a sheet | seat in storage space.
