Description

The present invention relates to a vehicle compartment partition device.

Patent Document 1 discloses a conventional vehicle compartment partition device in Figures 1 to 13. This vehicle compartment partition device is provided in a vehicle compartment. A first seat and a ceiling are present in the vehicle compartment. The first seat has a seat portion and a backrest portion. The seat portion is provided in the vehicle compartment so as to be movable in the front-rear direction. The backrest portion is connected to the seat portion and extends upward from the seat portion. Note that in this document, the first seat is specifically the driver's seat. The ceiling is located above the first seat and extends in the front-rear direction of the vehicle compartment.

The vehicle compartment partition device includes a partition curtain and a storage box. The partition curtain is curtain-shaped and flexible. This allows the partition curtain to bend freely. The partition curtain is disposed behind the first seat and extends in the front-rear and left-right directions of the vehicle compartment. The upper end of the partition curtain is fixed to the ceiling of the vehicle compartment. The storage box is fixed to the backrest portion and is located behind the upper part of the backrest portion and below the partition curtain. The lower end of the partition curtain is fixed inside the storage box. This allows the storage box to store a part of the partition curtain, including the lower end of the partition curtain, while rolling it up inside.

With this vehicle compartment partition device, a partition curtain is deployed inside the vehicle compartment, dividing the vehicle compartment into a front side and a rear side by the partition curtain. This makes it possible to adjust the air conditioning on both the front side and the rear side of the partition curtain inside the vehicle compartment.

Here, because the seat moves in the fore-and-aft direction, moving the seat in the fore-and-aft direction causes the first seat as a whole, including the backrest, to move in the fore-and-aft direction. And, as the first seat moves in the fore-and-aft direction, the storage box fixed to the backrest also moves in the fore-and-aft direction. In this regard, with this vehicle compartment partition device, when the storage box moves forward and approaches the front of the fixed position between the partition curtain and the ceiling, part of the partition curtain is rolled up inside the storage box. On the other hand, when the storage box moves rearward and moves away rearward from the fixed position between the partition curtain and the ceiling, the partition curtain stored inside the storage box is pulled out into the vehicle compartment.

Thus, with this vehicle compartment partition device, even if the storage box moves in the fore-and-aft direction as the seat and backrest move in the fore-and-aft direction, the partition curtain is less likely to become taut or bend significantly inside the vehicle compartment. Also, with this vehicle compartment partition device, because the storage box moves in the fore-and-aft direction together with the backrest, the partition curtain is prevented from interfering with the backrest when the seat and backrest move in the fore-and-aft direction.

JP 2014-125142 A

However, in the conventional vehicle compartment partition device described above, the partition curtain is curtain-shaped and flexible, so even if a portion of the partition curtain can be stored in the storage box, the partition curtain inevitably bends inside the vehicle compartment. For this reason, it is difficult for this vehicle compartment partition device to adequately separate the first seat from the ceiling in the front-to-rear direction.

Therefore, in this vehicle compartment partition device, it is conceivable to partition the interior of the vehicle compartment using a partition plate made of a rigid plate material, rather than a flexible curtain-like material such as a partition curtain.

Generally, the backrest not only moves in the fore-and-aft direction in conjunction with the fore-and-aft movement of the seat, but also oscillates in the fore-and-aft direction relative to the seat. However, if the partition curtain is replaced with a partition plate in such a vehicle compartment partition device, the upper end of the partition plate is fixed to the ceiling of the vehicle compartment, so the partition plate cannot move in the fore-and-aft direction within the vehicle compartment. This causes the partition plate to interfere with the backrest when it is oscillated backward. As a result, in such a vehicle compartment partition device, the oscillating function of the backrest is limited, reducing convenience.

On the other hand, if the partition plate is not fixed to the ceiling of the vehicle compartment, but is fixed only to the backrest, the partition plate can move together with the backrest when the backrest is swung, and so there is no interference between the partition plate and the backrest. However, in this case, the gap between the partition plate and the ceiling becomes larger when the backrest is swung, resulting in insufficient partitioning of the vehicle compartment.

The present invention was made in consideration of the above-mentioned conventional situation, and the problem to be solved is to provide a vehicle compartment partition device that is highly convenient and can effectively partition the vehicle compartment in the front-rear direction.

The vehicle compartment partition device of the present invention is a vehicle compartment partition device that is provided in a vehicle compartment having a first seat and a ceiling and divides the vehicle compartment in a front-rear direction,
The first seat has a seat portion provided in the vehicle compartment so as to be movable in the front-rear direction, and a backrest portion connected to the seat portion so as to be swingable in the front-rear direction relative to the seat portion,
The vehicle compartment partition device includes a first guide member provided on the ceiling and extending in the front-rear direction;
a partition plate formed of a plate material, disposed behind the first seat, and extending toward the ceiling beyond an upper end of the first seat;
a first connecting mechanism that connects the first guide member and the partition plate so that the partition plate can be guided in the front-rear direction by the first guide member;
a second connecting mechanism that connects the first seat and the partition plate such that a position of the backrest portion relative to the partition plate can be moved in a vertical direction of the vehicle compartment;
The second connecting mechanism includes a second guide member provided on the first seat and extending in the up-down direction;
a connecting member connected to the partition plate and movable in the up-down direction relative to the second guide member ,
A second seat is provided in the vehicle compartment and is disposed behind the first seat with the partition plate interposed therebetween,
An auxiliary partition plate formed of a plate material and extending downward beyond a lower end of the partition plate is connected to the partition plate,
The auxiliary partition plate is characterized in that it is swingable in the front-rear direction relative to the partition plate between the first seat and the second seat .

The vehicle compartment partition device of the present invention is equipped with a partition plate, which can divide the vehicle compartment in the front-rear direction, i.e., into a front portion and a rear portion, sandwiched between the partition plate. Here, the partition plate is formed of a plate material. Therefore, the partition plate has higher rigidity and is less likely to bend than a curtain-like object such as a partition curtain. As a result, the vehicle compartment partition device can suitably divide the vehicle compartment in the front-rear direction using the partition plate. In addition, in this vehicle compartment partition device, the partition plate and the first guide member are connected by a first connecting mechanism, so the partition plate can move in the front-rear direction within the vehicle compartment while being guided by the first guide member.

In addition, in this vehicle compartment partition device, the first seat and the partition plate are connected by a second connection mechanism. Here, the second connection mechanism has a second guide member and a connection member. The second guide member is provided on the first seat and extends in the vertical direction. The connection member is connected to the partition plate and is provided so as to be movable in the vertical direction relative to the second guide member. As a result, in this vehicle compartment partition device, the position of the backrest portion relative to the partition plate can be moved in the vertical direction by moving the connection member in the vertical direction relative to the second guide member.

Thus, in this vehicle compartment partition device, when the backrest of the first seat swings forward and backward relative to the seat, the partition plate moves forward and backward within the vehicle cabin, and the position of the backrest relative to the partition plate moves up and down. Specifically, when the backrest swings backward relative to the seat, the backrest presses the partition plate backward through the second connecting mechanism. As a result, the partition plate moves backward while being guided by the first guide member. At the same time, the backrest that swings backward attempts to move downward relative to the partition plate. At this time, in the second connecting mechanism, the connecting member moves the second guide member upward.

As a result, the second connecting mechanism moves the position of the backrest relative to the partition plate downward. As a result, in this vehicle compartment partition device, even if the partition plate is made of a plate material, interference between the backrest and the partition plate can be prevented when the backrest is swung in the forward and backward directions. Therefore, in this vehicle compartment partition device, there is no need to restrict the swing function of the backrest to prevent interference between the backrest and the partition plate.

In this vehicle compartment partition device, the partition plate is connected to the ceiling of the vehicle compartment via the first guide member while preventing interference between the backrest and the partition plate. This allows the vehicle compartment partition device to maintain a substantially constant gap between the ceiling and the partition plate regardless of the rocking of the backrest.

Therefore, the vehicle compartment partition device of the present invention is highly convenient and can effectively partition the vehicle compartment in the front-rear direction.

The vehicle compartment is provided with a second seat disposed behind the first seat across a partition plate. An auxiliary partition plate formed of a plate material and extending downward beyond a lower end of the partition plate is connected to the partition plate. The auxiliary partition plate is swingable in the front-rear direction relative to the partition plate between the first seat and the second seat .

Since the partition plate and the auxiliary partition plate are provided between the first seat and the second seat, the partition plate and the auxiliary partition plate can more suitably separate the first seat and the second seat in the front-rear direction. By swinging the auxiliary partition plate forward relative to the partition plate, a large space for the feet of the occupant in the second seat can be secured. Therefore, the auxiliary partition plate is less likely to be an obstacle when the second occupant gets in and out of the vehicle, and the auxiliary partition plate can be suitably prevented from contacting the knees of the occupant seated in the second seat. For these reasons, this vehicle compartment partition device exhibits higher convenience.

It is also preferable that the auxiliary partition plate is biased toward the first seat and abuts against the backrest. In this case, by abutting the auxiliary partition plate against the backrest, it is possible to hold the auxiliary partition plate in a state in which it swings forward relative to the partition plate. This makes it unnecessary to perform any special operation on the auxiliary partition plate when holding the auxiliary partition plate in a state in which it swings forward. In this way, this vehicle compartment partition device can easily ensure a wide foot space for the occupant in the second seat, thereby providing even greater convenience.

The vehicle compartment partition device of the present invention is highly convenient and can effectively partition the vehicle compartment in the front-rear direction.

The following describes an embodiment of the present invention with reference to the drawings.

As shown in Figures 1 to 3, the vehicle compartment partition device 1 of the embodiment is employed in a vehicle 100. Specifically, the vehicle 100 is a passenger car. The vehicle 100 has a vehicle compartment CR. Although not shown in detail, the vehicle 100 has a power unit and other components necessary for running in addition to the vehicle compartment CR. Also, in Figures 1 to 3, the vehicle compartment partition device 1 and other components are shown in a simplified form to facilitate explanation.

In this embodiment, the front-rear direction and the up-down direction of the vehicle compartment CR and the vehicle compartment partition device 1 are defined by the solid arrows shown in Figures 1 to 3. Also, in Figure 4, the up-down direction of the vehicle compartment CR and the vehicle compartment partition device 1 corresponding to Figures 1 to 3 is defined, as well as the left-right direction, which is the width direction of the vehicle compartment CR and the vehicle compartment partition device 1. Then, in Figures 5 and onwards, the front-rear direction, the up-down direction and the left-right direction of the vehicle compartment CR and the vehicle compartment partition device 1 are defined corresponding to Figures 1 to 4. These front-rear directions, up-down directions and left-right directions are mutually perpendicular.

As shown in Figures 1 to 3, the vehicle compartment CR has a ceiling 3 and a floor surface 5. The ceiling 3 is located at the upper end of the vehicle compartment CR, and extends in the front-rear and left-right directions. The floor surface 5 is located at the lower end of the vehicle compartment CR. The floor surface 5 faces the ceiling 3 in the up-down direction, and extends in the front-rear and left-right directions. The vehicle compartment CR also has a driver's seat 7 and a rear seat 9. The driver's seat 7 is an example of a "first seat" in the present invention. The rear seat 9 is an example of a "second seat" in the present invention. Although not shown, a passenger seat is provided to the left of the driver's seat 7 in the vehicle compartment CR.

The driver's seat 7 is located at the front right side of the vehicle compartment CR, and is available for a driver (not shown) of the vehicle 100 to sit in. The driver's seat 7 has a first seat portion 7a, a first backrest portion 7b, and a first headrest 7c. The first seat portion 7a is an example of the "seat portion" in the present invention. The first backrest portion 7b is an example of the "backrest portion" in the present invention.

The first seat portion 7a is attached to the floor surface 5 of the vehicle compartment CR via a first base frame 70, and is movable in the front-rear direction of the vehicle compartment CR. The first seat portion 7a is capable of supporting the driver's buttocks while being in contact with the driver's buttocks. The first backrest portion 7b extends upward from the first seat portion 7a. The first backrest portion 7b is capable of supporting the driver's back while being in contact with the driver's back. The first backrest portion 7b is connected to the rear of the first seat portion 7a, and is capable of swinging in the front-rear direction relative to the first seat portion 7a. As shown in FIG. 5, a first mounting hole 71 and a second mounting hole 72 are provided at the upper end of the first backrest portion 7b.

The first headrest 7c has a headrest body 73, a first connecting rod 74, and a second connecting rod 75. The headrest body 73 is capable of supporting the driver's head while being in contact with the head. The first connecting rod 74 and the second connecting rod 75 are fixed to the headrest body 73 and extend downward from the headrest body 73. The first headrest 7c is attached to the upper end of the first backrest portion 7b. The attachment of the first headrest 7c to the first backrest portion 7b will be described later.

As shown in Figures 1 to 3, the rear seat 9 is disposed behind the driver's seat 7 and is available for seating of passengers (not shown) of the vehicle 100 other than the driver. The rear seat 9 has a second seat portion 9a, a second backrest portion 9b, and a second headrest 9c. The second seat portion 9a is attached to the floor surface 5 of the vehicle compartment CR via a second base frame 90 and is movable in the fore-aft direction of the vehicle compartment CR. In addition to other configurations of the second seat portion 9a, the second backrest portion 9b and the second headrest 9c are configured similarly to the first seat portion 7a, the first backrest portion 7b, and the first headrest 7c, respectively.

As shown in Figures 1 to 4, the vehicle compartment partition device 1 is provided in the vehicle compartment CR. The vehicle compartment partition device 1 includes a first guide rail 11, a second guide rail 13, a partition plate 15, a first pulley member 17, a second pulley member 19, a right-side second coupling mechanism 21, a left-side second coupling mechanism 23, an auxiliary partition plate 25, a first connecting member 27, and a second connecting member 29. The first guide rail 11 and the second guide rail 13 are an example of a "first guide member" in the present invention. The first pulley member 17 and the second pulley member 19 are an example of a "first coupling mechanism" in the present invention. The right-side second coupling mechanism 21 and the left-side second coupling mechanism 23 are an example of a "second coupling mechanism" in the present invention. In Figure 4, the components of the vehicle compartment partition device 1, such as the first and second guide rails 11 and 13 and the partition plate 15, are exaggerated for ease of explanation. The same applies to Figure 5.

As shown in Figures 4 and 5, the first guide rail 11 and the second guide rail 13 are extrusions made of an aluminum alloy and extend a predetermined length in the longitudinal direction, i.e., the front-to-rear direction. The first guide rail 11 is formed with a first entrance 11a and a first guide path 11b. The first entrance 11a and the first guide path 11b extend from the front end to the rear end of the first guide rail 11. The second guide rail 13 has the same shape as the first guide rail 11 and is formed with a second entrance 13a and a second guide path 13b. The second entrance 13a and the second guide path 13b also extend from the front end to the rear end of the second guide rail 13. The first guide rail 11 and the second guide rail 13 may be made of resin.

As shown in FIG. 4, the first guide rail 11 and the second guide rail 13 are fixed to the ceiling 3 of the vehicle compartment CR with a predetermined gap between them in the left-right direction. As a result, the first guide rail 11 and the second guide rail 13 are located above the driver's seat 7 and the rear seat 9 in the vehicle compartment CR and extend in the front-rear direction. The length of the first and second guide rails 11 and 13 in the front-rear direction can be designed as appropriate, and the first and second guide rails 11 and 13 may extend beyond the rear seat 9 to the rear of the vehicle compartment CR. Furthermore, the first and second guide rails 11 and 13 may have a shape that extends in the front-rear direction while being convex upward, depending on the shape of the ceiling 3.

The first and second guide rails 11, 13 are fixed to the ceiling 3 with the first entrance 11a and the second entrance 13a facing downward toward the vehicle compartment CR. The main body 30 of the first pulley member 17 can enter the first entrance 11a, and the main body 30 of the second pulley member 19 can enter the second entrance 13a. The first and second rollers 31, 32 of the first pulley member 17 can enter the first guideway 11b, and the first and second rollers 31, 32 of the second pulley member 19 can enter the second guideway 13b. The configurations of the first pulley member 17 and the second pulley member 19 will be described later.

The partition plate 15 is a generally rectangular plate extending in the vertical and horizontal directions. The partition plate 15 is made of colorless and transparent polycarbonate. The partition plate 15 may be formed as a colored transparent plate. Also, the partition plate 15 may be formed as a partially or entirely opaque plate, provided that it does not interfere with the operation of the vehicle 100. Furthermore, the partition plate 15 may be formed from resins other than polycarbonate, such as acrylics or polyethylene terephthalate, or inorganic glass.

The vertical and horizontal lengths of the partition plate 15 are designed according to the size of the vehicle interior CR and the shape of the driver's seat 7. In this embodiment, the vertical length of the partition plate 15 is set to a length that reaches from the first guide rail 11 and the second guide rail 13, beyond the first headrest 7c, to the first backrest portion 7b. In other words, the partition plate 15 extends upward toward the ceiling 3 beyond the upper end of the first headrest 7c, i.e., the upper end of the driver's seat 7. In addition, the horizontal length of the partition plate 15 is set to be longer than the width of the first backrest portion 7b and therefore the driver's seat 7.

As shown in FIG. 5, the partition plate 15 is designed to have a first thickness T1. Here, the first thickness T1 is a thickness at which the partition plate 15 does not bend in the normal state, and the specific value of the first thickness T1 is designed based on the material of the partition plate 15 as well as the vertical and horizontal lengths of the partition plate 15. By setting the thickness to the first thickness T1 in this way, the partition plate 15 has a degree of rigidity that does not cause bending in the normal state. The normal state refers to a state in which the partition plate 15 is not being excessively pressed by the driver or passengers of the vehicle 100 when the vehicle compartment partition device 1 is in use.

The partition plate 15 is also formed with a first through hole 15a and a second through hole 15b. The first through hole 15a and the second through hole 15b are located at approximately the center of the partition plate 15 in the up-down direction, and penetrate the partition plate 15 in the front-rear direction. The first through hole 15a and the second through hole 15b are arranged in the partition plate 15 while being separated in the left-right direction. Here, the left-right distance between the first through hole 15a and the second through hole 15b is set to correspond to the left-right distance between the third guide rail 40 and the fourth guide rail 45 described later.

As shown in Figures 4 and 5, the first pulley member 17 and the second pulley member 19 have the same configuration, and each has a main body 30, a first roller 31, a second roller 32, and a first connecting shaft 33. The main body 30 is in the shape of a substantially rectangular box. Here, the left-right length of the main body 30 is set to be shorter than the left-right length of the first and second entrances 11a and 13a.

The first roller 31 is located to the right of the main body 30. Meanwhile, the second roller 32 is located to the left of the main body 30. The first roller 31 and the second roller 32 are formed in a disk shape with the same diameter. The first connecting shaft 33 extends in the left-right direction and is inserted rotatably into the main body 30. The first connecting shaft 33 connects the first and second rollers 31 and 32 to the right and left ends, respectively. This allows the first and second rollers 31 and 32 to rotate around the axis of the first connecting shaft 33 relative to the main body 30.

The first pulley member 17 has the main body 30 placed on the upper right side of the partition plate 15 and fixed to the partition plate 15 by two fixing screws 35. On the other hand, the second pulley member 19 has the main body 30 placed on the upper left side of the partition plate 15 and fixed to the partition plate 15 by two fixing screws 35. In this way, the first pulley member 17 and the second pulley member 19 are fixed to the upper part of the partition plate 15 while being separated in the left-right direction. Here, the left-right distance between the first pulley member 17 and the second pulley member 19 is set corresponding to the left-right distance between the first guide rail 11 and the second guide rail 13. The number of fixing screws 35 can be designed appropriately, and the first and second pulley members 17 and 19 may be fixed to the partition plate 15 by gluing the main body 30 to the partition plate 15.

As shown in FIG. 4, the first pulley member 17 allows the main body 30 to enter the first entrance 11a from the front end of the first guide rail 11, and allows the first and second rollers 31, 32 to enter the first guideway 11b. Similarly, the second pulley member 19 allows the main body 30 to enter the second entrance 13a from the front end of the second guide rail 13, and allows the first and second rollers 31, 32 to enter the second guideway 13b. In this way, the first pulley member 17 and the second pulley member 19 connect the first guide rail 11 and the second guide rail 13 to the partition plate 15. As a result, in the vehicle compartment CR, the partition plate 15 extends downward from the first and second guide rails 11, 13, and ultimately from the ceiling 3 of the vehicle compartment CR.

In the first and second pulley members 17 and 19, the first and second rollers 31 and 32 move in the front-rear direction along the first guideway 11b and the second guideway 13b, respectively, causing the main body portions 30 to move in the front-rear direction within the first entrance 11a and the second entrance 13a, respectively. This allows the partition plate 15 to move in the front-rear direction within the vehicle compartment CR while being guided by the first and second guide rails 11 and 13 (see Figures 1 to 3).

As shown in FIG. 5, the right-side second connecting mechanism 21 has a third guide rail 40, a first connecting bar 41, a first connecting pin 42, a third pulley member 43, and a first nut 44. The left-side second connecting mechanism 23 has a fourth guide rail 45, a second connecting bar 46, a second connecting pin 47, a fourth pulley member 48, and a second nut 49. The third guide rail 40 and the fourth guide rail 45 are an example of a "second guide member" in the present invention. Also, the third pulley member 43 and the fourth pulley member 48 are an example of a "connecting member" in the present invention.

As shown in FIG. 5, the third guide rail 40 and the fourth guide rail 45 are extrusions made of an aluminum alloy and extend a predetermined length in the longitudinal direction, i.e., in the vertical direction. The third guide rail 40 and the fourth guide rail 45 are formed to be equal in length. Here, the length of the third and fourth guide rails 40, 45 is formed to be shorter than the length of the first and second guide rails 11, 13. The third and fourth guide rails 40, 45 may also be made of resin.

The third guide rail 40 is formed with a third entrance 40a and a third guide path 40b. The third entrance 40a and the third guide path 40b extend from the upper end to the lower end of the third guide rail 40. The fourth guide rail 45 is formed with a fourth entrance 45a and a fourth guide path 45b. Similar to the third entrance 40a and the third guide path 40b, the fourth entrance 45a and the fourth guide path 45b extend from the upper end to the lower end of the fourth guide rail 45. In addition, a first fixing hole 40c is formed in the lower part of the third guide rail 40, and a second fixing hole 45c is formed in the lower part of the fourth guide rail 45.

The first connection bar 41 and the second connection bar 46 are made of resin and extend in the front-rear direction. A first insertion hole 41a is formed in the front end of the first connection bar 41, and a second insertion hole 46a is formed in the front end of the second connection bar 46. The first insertion hole 41a and the second insertion hole 46a penetrate the first connection bar 41 and the second connection bar 46 in the up-down direction, respectively. In addition, a first pin hole 41b is formed in the rear end of the first connection bar 41, and a second pin hole 46b is formed in the rear end of the second connection bar 46. The first pin hole 41b and the second pin hole 46b extend in the front-rear direction inside the first connection bar 41 and the second connection bar 46, respectively, and open at the rear ends of the first and second connection bars 41 and 46 (see Figures 6 and 7).

As shown in FIG. 5, the first connection bar 41 has the first pin hole 41b aligned with the first fixing hole 40c of the third guide rail 40. In this state, the first connection pin 42 is inserted into the first fixing hole 40c and the first pin hole 41b from the third guide rail 40 side. As a result, the first connection bar 41 is fixed to the lower part of the third guide rail 40 and extends forward from the third guide rail 40. Similarly, the second connection bar 46 is fixed to the lower part of the fourth guide rail 45 by the second connection pin 47 and extends forward from the fourth guide rail 45. Note that instead of the first and second connection pins 42 and 47, the first and second connection bars 41 and 46 may be fixed to the third and fourth guide rails 40 and 45, respectively, by screws, bolts, etc.

In this vehicle compartment partition device 1, the first connecting rod 74 of the first headrest 7c is inserted through the first insertion hole 41a, and the second connecting rod 75 of the first headrest 7c is inserted through the second insertion hole 46a. In this state, the first and second connecting rods 74 and 75 are inserted through the first and second mounting holes 71 and 72 of the first backrest portion 7b, respectively, and are held in the first and second mounting holes 71 and 72. In this way, the first headrest 7c is attached to the upper end of the first backrest portion 7b.

The first and second connecting bars 41, 46 are positioned between the first headrest 7c and the first backrest 7b, so that the third and fourth guide rails 40, 45 are attached to the first headrest 7c via the first and second connecting bars 41, 46. Thus, the third guide rail 40 and the fourth guide rail 45 are positioned behind the first headrest 7c with a gap between them in the left-right direction, and extend vertically in the up-down direction.

The third pulley member 43 and the fourth pulley member 48 have the same configuration, and each has a base 51, a shaft 52, a third roller 53, a fourth roller 54, and a second connecting shaft 55. As shown in Figures 6 and 7, the base 51 is formed in a cylindrical shape extending in the left-right direction. The shaft 52 is formed integrally with the base 51 and extends rearward from the base 51. The shaft 52 is formed with a smaller diameter than the first and second through holes 15a, 15b of the partition plate 15. In addition, a screw groove is formed in the shaft 52.

As shown in FIG. 5, the third roller 53 is located to the right of the base 51 and is formed in a disk shape with a larger diameter than the base 51. The fourth roller 54 is located to the left of the base 51. The fourth roller 54 is formed in a disk shape with the same diameter as the third roller 53. The second connecting shaft 55 extends in the left-right direction and is rotatably inserted into the base 51. The second connecting shaft 55 connects the third and fourth rollers 53 and 54 to the right and left ends, respectively. This allows the third and fourth rollers 53 and 54 to rotate around the axis of the second connecting shaft 55 relative to the base 51.

The third pulley member 43 and the fourth pulley member 48 are each disposed in front of the partition plate 15. The shaft portion 52 of the third pulley member 43 is inserted into the first through hole 15a from the front of the partition plate 15. The third pulley member 43 is fastened to the first nut 44 by screwing the first nut 44 onto the shaft portion 52 from the rear of the partition plate 15. Similarly, the shaft portion 52 of the fourth pulley member 48 is inserted into the second through hole 15b from the front of the partition plate 15 and fastened to the second nut 49 from the rear of the partition plate 15. In this way, the third and fourth pulley members 43 and 48 are attached to the partition plate 15.

The third pulley member 43 allows the base 51 to enter the third entrance 40a from the upper end of the third guide rail 40, and allows the third and fourth rollers 53, 54 to enter the third guideway 40b. Similarly, the fourth pulley member 48 allows the base 51 to enter the fourth entrance 45a from the upper end of the fourth guide rail 45, and allows the third and fourth rollers 53, 54 to enter the fourth guideway 45b.

In this way, the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23 connect the driver's seat 7 and the partition plate 15. As a result, the partition plate 15 is disposed behind the first backrest portion 7b and the first headrest 7c, and therefore behind the driver's seat 7, within the vehicle compartment CR. The partition plate 15 is also disposed in front of the rear seat 9 within the vehicle compartment CR. In other words, the rear seat 9 is disposed behind the driver's seat 7, with the partition plate 15 in between. In other words, in this vehicle compartment partition device 1, the partition plate 15 extends downward from the ceiling 3 between the driver's seat 7 and the rear seat 9.

In the third pulley member 43 and the fourth pulley member 48, the third and fourth rollers 53, 54 move vertically along the third guideway 40b and the fourth guideway 45b, respectively, causing the bases 51 to move vertically within the third entrance 40a and the fourth entrance 45a, respectively. This allows the third pulley member 43 and the fourth pulley member 48 to move vertically along the third and fourth guide rails 40, 45. As a result, the first backrest portion 7b and the first headrest 7c can move vertically relative to the partition plate 15.

Here, in the third pulley member 43 and the fourth pulley member 48, the shaft portions 52 have a smaller diameter than the first and second through holes 15a, 15b. Therefore, as shown in Fig. 6 and Fig. 7, the third pulley member 43 and the fourth pulley member 48 are allowed to move in the front-rear direction relative to the partition plate 15 when moving in the up-down direction on the third and fourth guide rails 40, 45.

As shown in Figures 4 and 5, the auxiliary partition plate 25 is disposed below the partition plate 15. The auxiliary partition plate 25 is a generally rectangular plate extending in the vertical and horizontal directions. Here, the vertical length of the auxiliary partition plate 25 is set to be shorter than the vertical length of the partition plate 15. In addition, the horizontal length of the auxiliary partition plate 25 is set to be equal to the horizontal length of the partition plate 15. The shape of the auxiliary partition plate 25 can be designed as appropriate.

The auxiliary partition plate 25 is made of colorless and transparent polycarbonate, like the partition plate 15. The auxiliary partition plate 25 is also designed to have a plate thickness of the first thickness T1. This allows the auxiliary partition plate 25 to have a degree of rigidity that does not cause bending in the normal state. Here, the normal state of the auxiliary partition plate 25 refers to a state in which the auxiliary partition plate 25 is not excessively pressed by the driver or passengers of the vehicle 100 when the vehicle compartment partition device 1 is in use. The auxiliary partition plate 25 may be colored and transparent, or may be opaque. The thickness of the auxiliary partition plate 25 may be different from the thickness of the partition plate 15. Furthermore, the auxiliary partition plate 25 may be formed of a resin other than polycarbonate or inorganic glass, and the partition plate 15 and the auxiliary partition plate 25 may be formed of different materials.

The first connecting member 27 and the second connecting member 29 have the same configuration, and each has a first plate 61, a second plate 62, and a biasing link 63. The first plate 61 and the second plate 62 have the same shape, and are generally rectangular plates. The biasing link 63 is disposed between the first plate 61 and the second plate 62, and connects the first plate 61 and the second plate 62 so that they can swing in the front-rear direction. At this time, the biasing link 63 biases and connects the first plate 61 and the second plate 62 so that the first plate 61 and the second plate 62 approach each other, i.e., so that the first connecting member 27 and the second connecting member 29 close.

The first connecting member 27 and the second connecting member 29 are disposed between the partition plate 15 and the auxiliary partition plate 25 with a predetermined distance provided in the left-right direction. The first connecting member 27 and the second connecting member 29 fix the first plate 61 to the lower end of the partition plate 15 and fix the second plate 62 to the upper end of the auxiliary partition plate 25. Thus, the first connecting member 27 and the second connecting member 29 connect the auxiliary partition plate 25 to the lower side of the partition plate 15. As a result, the auxiliary partition plate 25 is connected to the lower side of the partition plate 15 and extends downward beyond the lower end of the partition plate 15 between the driver's seat 7 and the rear seat 9.

Here, the first connecting member 27 and the second connecting member 29 are biased by the biasing link 63 so that the first plate 61 and the second plate 62 approach each other. Therefore, by connecting the partition plate 15 and the auxiliary partition plate 25 by the first and second connecting members 27 and 29, the auxiliary partition plate 25 can swing in the front-rear direction relative to the partition plate 15, and is always in a state of swinging forward relative to the partition plate 15. Therefore, as shown in Figures 1 to 3, in this vehicle compartment partition device 1, the lower end of the auxiliary partition plate 25 always abuts against the first backrest portion 7b.

In the vehicle compartment partition device 1 configured as above, the partition plate 15 and the auxiliary partition plate 25 can partition the vehicle compartment CR between the driver's seat 7 and the rear seat 9 in the front-rear direction. Here, the partition plate 15 and the auxiliary partition plate 25 are made of polycarbonate, and the plate thickness is designed to be the first thickness T1, so that rigidity is ensured. Therefore, the partition plate 15 and the auxiliary partition plate 25 have higher rigidity than a curtain-like object such as a partition curtain, and are less likely to bend during use. As a result, in the vehicle compartment partition device 1, the partition plate 15 and the auxiliary partition plate 25 can suitably partition the driver's seat 7 and the rear seat 9 in the front-rear direction. As a result, in the vehicle 100 employing this vehicle compartment partition device 1, it is possible to suitably adjust the air conditioning in the vehicle compartment CR in the front part of the partition plate 15 and the auxiliary partition plate 25 including the driver's seat 7 and the rear part of the partition plate 15 and the auxiliary partition plate 25 including the rear seat 9.

In addition, because the partition plate 15 and the auxiliary partition plate 25 have rigidity, when this vehicle compartment partition device 1 is used in a transportation vehicle such as a taxi, it can also provide a high crime prevention effect for the driver sitting in the driver's seat 7.

In this vehicle compartment partition device 1, the partition plate 15 and the first and second guide rails 11, 13 are connected by the first and second pulley members 17, 19. Therefore, in this vehicle compartment partition device 1, when the first seat portion 7a, and therefore the driver's seat 7, moves in the front-rear direction within the vehicle compartment CR, the partition plate 15 and the auxiliary partition plate 25 can move in the front-rear direction within the vehicle compartment CR while being guided by the first and second guide rails 11, 13.

Specifically, when the driver's seat 7 moves rearward from the position shown in FIG. 1 to the position shown in FIG. 2 in the vehicle compartment CR, the partition plate 15 and the auxiliary partition plate 25 move rearward in the vehicle compartment CR while being guided by the first and second guide rails 11 and 13. Also, when the driver's seat 7 moves forward from the position shown in FIG. 2 to the position shown in FIG. 1, the partition plate 15 and the auxiliary partition plate 25 move forward in the vehicle compartment CR while being guided by the first and second guide rails 11 and 13. As a result, in this vehicle compartment partition device 1, even if the driver's seat 7 moves rearward in the vehicle compartment CR, the partition plate 15 and the auxiliary partition plate 25 do not interfere with the first backrest portion 7b of the driver's seat 7, and the partition plate 15 and the auxiliary partition plate 25 do not restrict the rearward movement of the driver's seat 7. Also, the partition plate 15 and the auxiliary partition plate 25 do not restrict the forward movement of the driver's seat 7.

In addition, in this vehicle compartment partition device 1, the driver's seat 7 and the partition plate 15 are connected by the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23. Here, the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23 have the third and fourth guide rails 40, 45 and the third and fourth pulley members 43, 48. The third and fourth guide rails 40, 45 are attached to the first headrest 7c and extend in the vertical direction behind the first headrest 7c. The third and fourth pulley members 43, 48 are connected to the partition plate 15 and can move in the vertical direction relative to the third and fourth guide rails 40, 45. As a result, in this vehicle compartment partition device 1, the third and fourth pulley members 43, 48 move in the vertical direction relative to the third and fourth guide rails 40, 45, so that the positions of the first backrest portion 7b and the first headrest 7c relative to the partition plate 15 can be moved in the vertical direction.

Thus, in this vehicle compartment partition device 1, when the first backrest portion 7b of the driver's seat 7 swings forward and backward relative to the first seat portion 7a, the partition plate 15 and the auxiliary partition plate 25 move forward and backward between the driver's seat 7 and the rear seat 9, and the positions of the first backrest portion 7b and the first headrest 7c relative to the partition plate 15 move vertically.

Specifically, in the driver's seat 7, when the first backrest portion 7b pivots rearward relative to the first seat portion 7a from the position shown in FIG. 1 to the position shown in FIG. 3, the first backrest portion 7b and the first headrest 7c tilt toward the rear seat 9. As a result, the first backrest portion 7b and the first headrest 7c press the partition plate 15 rearward through the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23. Therefore, the partition plate 15 and the auxiliary partition plate 25 move rearward while being guided by the first and second guide rails 11 and 13.

At the same time, the inclined first backrest portion 7b and first headrest 7c attempt to move downward relative to the partition plate 15. At this time, in the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23, the third and fourth pulley members 43, 48 move upward relative to the third and fourth guide rails 40, 45.

That is, by tilting the first backrest portion 7b and the first headrest 7c, in the right-side second connecting mechanism 21, the third guide rail 40 tilts from the position shown in FIG. 6 to the position shown in FIG. 7. Although not shown, in the left-side second connecting mechanism 23, the fourth guide rail 45 tilts in the same manner. Then, in the process of tilting the third and fourth guide rails 40, 45 in this way, in the third pulley member 43, the third and fourth rollers 53, 54 move upward in the third guide path 40b from the position shown in FIG. 6 to the position shown in FIG. 7, and the base 51 moves upward in the third entrance 40a from the position shown in FIG. 6 to the position shown in FIG. 7. As a result, as shown by the white arrow in FIG. 7, the third pulley member 43 moves upward on the tilting third guide rail 40. Similarly, in the fourth pulley member 48, the third and fourth rollers 53 and 54 move upward in the fourth guideway 45b, and the base 51 moves upward in the fourth entrance 45a. In this way, the fourth pulley member 48 also moves upward on the inclined fourth guide rail 45.

As a result, the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23 move the positions of the first backrest 7b and the first headrest 7c, including the third and fourth guide rails 40, 45, downward relative to the partition plate 15. As a result, in this vehicle compartment partition device 1, even if the partition plate 15 is made of a plate material and has rigidity, it is possible to prevent interference between the first backrest 7b and the first headrest 7c and the partition plate 15 when the first backrest 7b and the first headrest 7c are swung backward. In this vehicle compartment partition device 1, if the first backrest 7b and the first headrest 7c are swung forward from the position shown in FIG. 3 to the position shown in FIG. 1, the third and fourth pulley members 43, 48 in the right-side second connecting mechanism 21 and the left-side second connecting mechanism 23 move the third and fourth guide rails 40, 45 downward from the position shown in FIG. 7 to the position shown in FIG. 6, respectively.

Thus, in a vehicle 100 employing this vehicle compartment partition device 1, the driver's seat 7 is connected to the partition plate 15 and is capable of swinging the first backrest portion 7b and the first headrest 7c in the front-rear direction between the position shown in FIG. 1 and the position shown in FIG. 3. Thus, in this vehicle compartment partition device 1, there is no need to restrict the swinging function of the first backrest portion 7b in order to prevent interference between the first backrest portion 7b and the first headrest 7c and the partition plate 15.

As described above, this vehicle compartment partition device 1 can connect the partition plate 15 to the ceiling 3 of the vehicle compartment CR via the first and second guide rails 11, 13 while preventing interference between the first backrest portion 7b and the first headrest 7c and the partition plate 15. Therefore, this vehicle compartment partition device 1 can maintain a substantially constant gap between the ceiling 3 and the partition plate 15 regardless of the rocking of the first backrest portion 7b. In this respect, this vehicle compartment partition device 1 can appropriately adjust the air conditioning in the vehicle compartment CR at the front and rear portions of the partition plate 15 and the auxiliary partition plate 25.

Therefore, the vehicle compartment partition device 1 of the embodiment is highly convenient and can effectively partition the vehicle compartment CR in the front-rear direction.

In particular, in this vehicle compartment partition device 1, because the auxiliary partition plate 25 is connected below the partition plate 15, it is possible to more effectively separate the vehicle compartment CR between the driver's seat 7 and the rear seat 9 compared to a case in which the partition plate 15 alone is used to separate the vehicle compartment CR in the fore-aft direction between the driver's seat 7 and the rear seat 9. And, like the partition plate 15, the auxiliary partition plate 25 is also made of polycarbonate, ensuring rigidity. Therefore, with this vehicle compartment partition device 1, it is possible to sufficiently improve the air conditioning effect of the vehicle compartment CR and the crime prevention effect for the driver.

In addition, the auxiliary partition plate 25 is connected to the partition plate 15 by the first connecting member 27 and the second connecting member 29, so that it is biased forward relative to the partition plate 15 and is always in contact with the first backrest portion 7b. As a result, in this vehicle compartment partition device 1, it is possible to ensure a wide space for the feet of the occupants in the rear seat 9 even when the auxiliary partition plate 25 is provided. Therefore, in this vehicle compartment partition device 1, the auxiliary partition plate 25 is less likely to interfere with the occupants getting on and off the rear seat 9, and the auxiliary partition plate 25 is preferably prevented from contacting the knees of the occupants seated in the rear seat 9. Furthermore, in this vehicle compartment partition device 1, the driver or the occupants in the rear seat 9 do not need to swing the auxiliary partition plate 25 forward to ensure a wide space for the feet of the occupants in the rear seat 9. In this respect, too, this vehicle compartment partition device 1 is highly convenient.

Although the present invention has been described above with reference to examples, it goes without saying that the present invention is not limited to the above examples and can be modified as appropriate without departing from the spirit of the invention.
