  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a floor panel 2 constituting a floor surface of a vehicle body 1 (namely, main body) of an automobile according to the present invention, and a pair of seat cushions 3 and 3A which are arranged in a vehicle compartment and used side by side. It is a schematic perspective view which shows the relationship with these. The arrow Fr in this figure and other figures indicates the forward direction of the automobile, and the arrow W indicates the vehicle width direction. In addition, the words “front” or “rear” in the present specification mean front and rear with respect to the forward direction Fr of the automobile.

  The pair of seat cushions 3 and 3A, which are not shown in FIG. 1 and serve to support the butt of the seated person, are respectively provided with seat backs 4 and 4A that support the back of the seated person. A rear seat 5 is constituted by 3A and the entire seat back 4, 4A. In front of the rear seat 5, a front seat (not shown), that is, a driver seat and a passenger seat are arranged side by side in the vehicle width direction W. In addition, a rear of the rear seat 5 is partitioned with a luggage compartment R for storing luggage (not shown).

  FIG. 2 is a side view showing one of the seat cushions 3 shown in FIG. 1 and the seat back 4 attached to the seat cushion 3. As shown by a solid line in FIG. 2, the seat back 4 is connected to a rear portion of the seat cushion 4 via a pivot 6 so as to be rotatable in directions indicated by arrows A and B. The other seat back 4A shown in FIG. 1 is also connected to the rear portion of the seat cushion 3A so as to be rotatable in the directions of arrows A and B (FIG. 2) via a pivot in the same manner.

  On the other hand, as shown by a solid line in FIG. 2, a front bracket 7 is fixed to the front portion of one seat cushion 3, and the front bracket 7 is pivotally attached to a front pedestal 8 fixed to the floor panel 2. 9 is rotatably connected. As a result, the seat cushion 3 is supported by the floor panel 2 together with the seat back 4 so as to be rotatable around the pivot pin 9 in the directions indicated by arrows C and D. Further, as shown by a solid line in FIG. 2, the rear portion of the seat cushion 3 is placed on a rear pedestal 10 fixed to the floor panel 2. The other seat cushion 3A shown in FIG. 1 is also supported by the floor panel 2 via a front bracket, a pivot pin, a front pedestal, and a rear pedestal which are not shown, just like the one seat cushion 3.

  The seat cushions 3 and 3A and the seat backs 4 and 4A are used in a state where the seat cushions 3 and 3A occupy the use positions shown by solid lines in FIGS. The backs 4 and 4A support the back of the seated person. Further, these can be stored as shown below in a state where no seated person is seated on the seat cushions 3, 3A and the seat backs 4, 4A.

  First, the seat back 4 in the use position indicated by the solid line in FIG. 2 is rotated around the pivot 6 in the direction of arrow A, and the seat back 4 is moved forward to the position indicated by the broken line in FIG. Next, the seat cushion 3 together with the seat back 4 is rotated around the pivot pin 9 in the direction of arrow C, and the seat cushion 3 together with the seat back 4 is rotated to the stowed storage position shown by a two-dot chain line in FIG. Move. By the reverse operation, the seat cushion 3 and the seat back 4 can be brought to the use position shown by the solid line in FIG.

  The other seat cushion 3A and the seat back 4A shown in FIG. 1 are also rotated to the storage position or rotated from the storage position to the use position in the same manner as described above with reference to FIG. Can be moved. Thus, the seat cushions 3 and 3A are supported by the floor panel 2 so as to be rotatable between a use position where the seat cushion can be supported and a stowed storage position. By bringing the seat cushions 3, 3 A and the seat backs 4, 4 A to the storage position, it is possible to expand the luggage storage space including the luggage compartment R behind the rear seat 5, and accommodate larger luggage such as a wheelchair. And can be transported.

  In the illustrated example, the seat cushions 3 and 3A are supported on the floor panel 2 via the front bracket, the pivot pin, the front pedestal, and the rear pedestal, but other intermediate members, for example, a seat that slides the seat cushion back and forth. The seat cushions 3 and 3A can be supported on the floor panel 2 via a truck or the like, or the seat cushions 3 and 3A can be directly supported on the floor panel 2. Also in these cases, each of the seat cushions 3 and 3A is supported by the floor panel 2 so as to be rotatable between a use position where the seat cushion can be supported and a stowed storage position.

  FIG. 3A is a plan view of the seat cushions 3 and 3A occupying the use position as seen from above. As can be seen from FIG. 2 and FIG. 2, locking devices 11 and 11A are provided on the bottom surfaces of the seat cushions 3 and 3A, respectively. Both locking devices 11, 11A attached to the respective seat cushions 3, 3A are located next to each other when both seat cushions 3, 3A are in the use position. In the illustrated example, the locking devices 11 and 11A are respectively provided on the bottom surfaces of the seat cushions 3 and 3A on the vehicle inner side.

  FIG. 4 is a perspective view showing details of the two locking devices 11 and 11A described above, omitting the illustration of the seat cushions 3 and 3A. Both locking devices 11 and 11A have substantially the same structure, and the configuration itself is well known. Therefore, the configuration of the lock devices 11 and 11A will be briefly described. Each lock device 11 and 11A has a casing 12 and 12A, and hooks 13 and 13A that are rotatably supported by the casings 12 and 12A. The casing 12 of one locking device 11 is fixed to the bottom of the frame of one seat cushion 3 by bolts and nuts (not shown), and the casing 12A of the other locking device 11A is also not shown. And the nut are fixed to the bottom surface of the frame of the other seat cushion 3A. Such locking devices 11 and 11A are made of a high-strength material, for example, a steel plate. As each locking device, in addition to a device of the illustrated type, a device of an appropriate form known per se can be adopted.

  Moreover, as shown to (a) of FIG. 3 and FIG. 4, the one striker 14 is provided corresponding to both the locking devices 11 and 11A. The striker 14 shown as an example in FIG. 4 is integrally connected to a pair of vertical portions 15 and 15A that are spaced apart from each other and the lower ends of the vertical portions 15 and 15A. The base end portions 16 and 16A are fixed to each other and the horizontal portion 17 integrally connecting the upper ends of the vertical portions 15 and 15A. The vertical portions 15 and 15A, the base end portions 16 and 16A, and the horizontal portion 17 include It is configured as an integral member. The striker 14 is made of a high-strength material such as steel.

  When the seat cushions 3 and 3A are in the use positions shown in FIG. 1, the hooks 13 and 13A of the locking devices 11 and 11A attached to the seat cushions 3 and 3A are, as shown in FIG. 2 is engaged with a horizontal portion 17 of one striker 14 fixed to 2. For this reason, each seat cushion 3 and 3A is fixed with respect to the floor panel 2, and is locked to the use position.

  When the seat cushions 3 and 3A are rotated to the above-described storage positions, an operation lever (not shown) provided at the front portion of the seat cushions 3 and 3A is rotated. Then, the operation is transmitted to the lock devices 11 and 11A via a wire (not shown), the hooks 13 and 13A are rotated, and the hooks 13 and 13A are detached from the striker 14. In this way, by releasing the engagement of the hooks 13 and 13A with the striker 14, the seat cushions 3 and 3A can be rotated to their storage positions as described above. When the seat cushions 3 and 3A are rotated again to the use position, the hooks 13 and 13A of the lock devices 11 and 11A hit the striker 14 and are rotated by an external force received from the striker 14 to rotate the horizontal portion 17 of the striker 14. Engage with. Thereby, each seat cushion 3, 3A is locked in the use position again. Thus, the hooks 13 and 13A of the two lock devices 11 and 11A are engaged with and disengaged from the horizontal portion 17 of the striker 14 to lock the seat cushion 33A or to release the lock.

  As described above, in the automobile of the present example, the two lock devices that are attached to the respective seat cushions 3 and 3A and are adjacent to each other when both the seat cushions 3 and 3A are in the use position. The striker 14 that engages with the hooks 13 and 13A of the 11 and 11A is constituted by a single common member. For this reason, the number of strikers can be made smaller than before. As a result, the weight and cost of the automobile can be reduced, and the structure can be simplified. Conventionally, since one striker was provided for each locking device, the number of strikers increased, which could increase the weight and cost of the vehicle and complicate the structure of the vehicle. (See (c) and (d) of FIG. 5). Such a problem can be prevented by the configuration according to the present invention.

  Moreover, as shown in FIG. 5 (a), the bottom surface of the narrow recess 18 formed in the floor panel 2 and the width L formed in the floor panel 2 as shown in FIG. 5 (b). Even when the striker 14 is fixed to the top surface of the narrow convex portion 19, the number of the strikers is one, so that the striker 14 can be fixed to the floor panel 2 with a margin. On the other hand, as is clear from FIGS. 5C and 5D showing the conventional example, the two concave portions 18 and the convex portions 19 having a small width L of the floor panel 2 are provided for the two locking devices 11 and 11A. It is not easy to arrange the two strikers 14A and 14B side by side and fix them to the floor panel 2. In FIG. 5, both locking devices 11 and 11A are simplified (the same applies to FIGS. 6 to 8).

  Further, as shown in FIG. 3B, when the locking devices 20 and 20A are attached to the seat cushions 3 and 3A in addition to the locking devices 11 and 11A, respectively, One striker 21, 21A may be provided for each of the locking devices 20, 20A. Also in this case, since only one striker 14 needs to be provided for the above-described locking devices 11 and 11A, the total number of strikers can be reduced as compared with the conventional case.

  As can be seen from the striker 14 shown in FIG. 4 and the two locking devices 11 and 11A shown in FIGS. 6A and 6B, a large impact force is applied to the driving vehicle. 6 is applied to the locking devices 11 and 11A from the seat cushions 3 and 3A shown in FIG. 1, whereby a central portion of the horizontal portion 17 of the striker 14 is applied. Is elastically deformed in a direction slightly protruding upward. Then, as shown by the arrow G in FIG. 6B, the two locking devices 11 and 11A move along the horizontal portion 17 of the striker 14 toward the central portion thereof. For this reason, a large concentrated load is applied from the two locking devices 11 and 11A to the central portion of the horizontal portion 17 of the striker 14, and as shown in FIG. 6B, the horizontal portion 17 of the striker 14 The central portion is greatly plastically deformed in a direction protruding upward. As a result, both locking devices 11 and 11A collide violently, and there is a possibility that these locking devices 11 and 11A are damaged.

  Therefore, when both the seat cushions 3 and 3A are in the use position, a spacer 22 is provided between the two locking devices 11 and 11A located adjacent to each other as shown in FIG. It is preferable. If the spacers 22 are provided in this way, a large external force F is applied to the locking devices 11 and 11A as shown in FIG. 7A, and the horizontal portion 17 of the striker 14 is slightly deformed. Even if 11 and 11A move in directions approaching each other as indicated by an arrow G in FIG. 7B, a spacer is provided between these locking devices 11 and 11A as shown in FIG. 7B. Since 22 is provided, even if both locking devices 11 and 11A hit the spacer 22, both locking devices 11 and 11A do not hit directly. For this reason, it can prevent that the locking devices 11 and 11A are damaged severely. Moreover, as can be seen from FIG. 7B, external force is applied to the horizontal portion 17 of the striker 14 from the two locking devices 11 and 11A that are largely separated from each other. As shown in (b), there is no significant deformation or breakage.

  As described above, the spacer 22 serves to prevent the two locking devices 11 and 11A from approaching and colliding with each other even when an external force is applied to the striker 14 and the striker 14 is deformed. is there.

  The spacer described above can be configured in various forms, and one specific example thereof will be clarified below.

  8A is a front view showing the relationship between the spacer 22, the striker 14, and the two locking devices 11 and 11A, and FIG. 8B is a view taken along line VIII-VIII in FIG. 8A. It is a line expanded sectional view. As can be seen from these drawings, the spacer 22 shown here is in the state that the hooks 13 and 13A (FIG. 4) of the two locking devices 11 and 11A are both engaged with the horizontal portion 17 of the striker 14. It consists of a substantially C-shaped resin member fitted into the horizontal portion 17 between the two locking devices 11, 11A. The intermediate portion 23 of the C-shaped spacer 22 is formed as an integral hinge that is thinner than the other spacer portions. Therefore, as shown in FIG. 8B, by applying an external force to the spacer 22 in such a direction that the both end portions 24 of the spacer 22 are separated from each other, the spacer 22 is elastically deformed in the direction of the arrow E and spreads. be able to. Thus, by expanding the C-shaped spacer 22, the spacer 22 can be easily detached from the horizontal portion 17 of the striker 14, or conversely, the spacer 22 can be easily attached to the horizontal portion 17.

  As described above, the spacer 22 is detachably fitted to the portion of the horizontal portion 17 between the two locking devices 11 and 11A, and is elastically deformed in the direction of expanding the substantially C-shaped spacer 22, The spacer 22 can be attached to and detached from the horizontal portion 17 of the striker 14.

  As described above, the example in which the present invention is applied to a vehicle in which the pair of seat cushions 3 and 3A are rotated forward to bring the seat cushions 3 and 3A to the retracted position has been shown. It can be widely applied to automobiles other than models. For example, as described in Patent Documents 1 and 2 mentioned above, an automobile or a pair of seats in which the seat cushion is rotated outward in the vehicle width direction and is stored in the storage position. The present invention can also be applied to an automobile in which cushions are arranged in the front-rear direction behind the front seat.

  As mentioned above, although preferable embodiment of this invention was described, this invention can be variously modified without being limited to this embodiment.
