Description

  The present invention relates to a vehicle seat moving device. More specifically, the present invention relates to a vehicle seat moving device that enables the seat to move in the vehicle front-rear direction and the vehicle width direction in order to change the seat arrangement of the vehicle seat.

As this type of vehicle seat moving device, for example, a technique disclosed in Patent Document 1 described below is known.
In this disclosed technique, a plurality of seats arranged in the vehicle front-rear direction and the vehicle width direction are configured to be slidable along a mesh-like slide groove formed on the floor surface. Specifically, a leg portion that is slidably engaged with the slide groove is provided at the lower portion of each seat. The slide grooves are formed in a continuous manner in the front-rear direction and the vehicle width direction so that the slide movements of the respective sheets communicate with each other. Thereby, the width of the slide movement of each sheet is widened, and the degree of freedom of the seat arrangement can be improved.

JP 2002-120604 A

  However, in the above-described conventional technology, for example, the technology disclosed in Patent Document 1, each seat can be smoothly slid along the slide groove, but the load applied in the vehicle longitudinal direction of the seat is supported only by the leg portion. Because of this configuration, for example, the seat is unsuitable for being configured to withstand a relatively large load such as a vehicle collision. In order to increase the support strength of the seat, a configuration such as a lock mechanism having a high support strength must be set separately. In such a case, the entire structure becomes complicated.

  The present invention was created to solve the above-described problems, and the problem to be solved by the present invention is to improve the degree of freedom of seat arrangement of a vehicle seat with a relatively simple configuration. It is possible to support the vehicle floor with sufficient support strength when seated.

In order to solve the above problems, the vehicle seat moving apparatus of the present invention takes the following means.
First, the first invention is the longitudinal direction of the slide rail extending in an elongated shape in a direction after the car both front on the position of the right and left two locations on the vehicle floor are extended, along the shape of each slide rail seat There Ru mobile device der vehicle seat adapted to be slid guided in the longitudinal direction of the vehicle. The seat is guided to slide in a state in which the upper rail having a predetermined width in the front-rear direction is engaged with the slide rail on each side while being prevented from being peeled from the slide rail on each side. In addition, the configuration having a predetermined width in the front-rear direction of the upper rail is configured so that the support strength when the slide lock is slide-locked to the slide rail on each side is satisfied. It is said that. Further, between the slide rails in the front-rear direction, a slide rail in the vehicle width direction is provided extending between the slide rails so that the seat slides and moves in the vehicle width direction. The changeover movement that switches between a state in which the seat can be slid on the slide rail in the front-rear direction on each side and a state in which the seat can be slid on the slide rail in the vehicle width direction is performed by a turntable disposed on the vehicle floor. It is performed by moving it to the top and rotating it. The turntable is provided with a lower rail member that can be engaged in a state in which the upper rail is received and prevented from peeling by sliding the upper rail provided on the seat along the slide rail in the front-rear direction on each side. ing. The upper rail is perpendicular to the slide movement direction with respect to each rail, assuming that the entire shape having a predetermined width in the front-rear direction is received and engaged with the slide rail and the lower rail member in the front-rear direction on each side. It engages as a state in which movement in the lateral direction is restricted.
According to a first aspect of this, the sheet is before and after the entire shape of the upper rail having a predetermined width direction engages slidably in the longitudinal direction of the slide rail on each side by sliding guide structure Thus, the structure having the predetermined width of the upper rail is enhanced so that the support strength when being slide-locked with respect to the slide rail on each side is satisfied. Further, the upper rail engages with the slide rail in the front-rear direction on each side and the lower rail member on the turntable in a state in which movement in the lateral direction perpendicular to the slide movement direction is restricted. It is like that. Thereby, the movement which moves an upper rail from the slide rail of the front-back direction of each side to a lower rail member, and the reverse movement can be performed smoothly .

Next, according to a second aspect, in the first aspect described above, the slide rail in the vehicle width direction is disposed at a position off the rear end portion side of both slide rails in the front-rear direction. The turntable is arranged in two locations, each arranged at a position deviated from the rear end side of each slide rail in the front-rear direction. Each of the turntables, by their rotation, has a direction in which the direction of each lower rail member is connected to the rear end of each slide rail in the front-rear direction and a direction in which the direction is connected to each end of the slide rail in the vehicle width direction. that has become a structure to switch.
According to the second aspect of the invention, the seat is received into the lower rail member on each turntable by removing the upper rail from the slide rail in the front-rear direction to the rear end side. And from this state, by rotating the turntable, the direction of the lower rail member is changed to the direction connected to each end of the slide rail in the vehicle width direction, and the seat moves along the slide rail in the vehicle width direction. to a state capable of sliding and switched Ru.

Next, according to a third aspect of the present invention, in the second aspect described above, each rotary disk is interlocked with each other so that each lower rail member is switched in such a manner that the directions of the lower rail members are simultaneously directed in the same direction. To be done.
According to the third aspect of the invention, by rotating one of the turntables so that the lower rail member is directed to connect to the end of the slide rail in the vehicle width direction, the rotation beyond the slide rail in the vehicle width direction is performed. board is also Ru directed in a direction capable of receiving the upper rail by connecting the lower rail member and the end portion in the vehicle width direction of the slide rail.

Next, according to a fourth aspect of the present invention, in any one of the first to third aspects described above, the slide rails in the front-rear direction and the slide rail in the vehicle width direction have the same cross-sectional shape, and the upper rail is a shape which can be engaged to accept the length of extension of the rails, that has become one with the lower rail member provided on the turntable is formed as a lower rail having the same cross-sectional shape.
According to the fourth aspect of the invention, the slide rails in the front-rear direction, the slide rail in the vehicle width direction, and the lower rail member provided on the turntable are formed by rails having the same cross-sectional shape. Therefore, these rails can be formed using common parts.

The present invention can obtain the following effects by taking the above-described means.
First, according to the first invention, a slide rail in the vehicle width direction is provided between both slide rails in the front-rear direction, and a seat can be moved back and forth between these slide rails by a rotating disk, so that it is relatively simple. The structure which can improve the freedom degree of a seat arrangement by a structure can be obtained. In addition, since the seat is configured to engage with both slide rails in the front-rear direction via the upper rail having a predetermined width in the front-rear direction, the configuration can improve the degree of freedom of the seat arrangement as described above. It can configure and to Rukoto with enhanced support strength for each side of the slide rail of the seat.
Furthermore, according to the second invention, the rotating disk is disposed at a position off the rear end side of both slide rails in the front-rear direction, so that the rotating disk is located at a midpoint between both slide rails in the front-rear direction. Compared to the case where it is arranged, the seat is simply mounted on the rotating plate by moving the seat to the rear end side of both slide rails without adjusting the position of the slide position in the front-rear direction of the seat. It can be Rukoto and the state of being location.
Furthermore, according to the third aspect of the present invention, the rotation of the rotating disks can be made to rotate together so that the directions of the lower rail members are simultaneously directed in the same direction. When the slide is moved, the lower rail on the turntable at the slide destination position can always be oriented in the direction that can accept the upper rail, making it easier to move the seat between the slide rails. it is possible to allow.
Further, according to the fourth aspect of the invention, the slide rails in the front-rear direction and the slide rail in the vehicle width direction are configured by having the same cross-sectional shape, and the lower rail member provided on the turntable is also the rails described above. with the arrangements by one having the same cross-sectional shape as can you to easily molded using these rails common parts.

  Embodiments of the best mode for carrying out the present invention will be described below with reference to the drawings.

  First, the configuration of the vehicle seat moving device according to the first embodiment will be described with reference to FIGS. FIG. 1 is a plan view showing a schematic configuration of a vehicle seat moving device, and FIG. 2 shows a state in which a seat 10 placed on a rotating disk 41B on the right side of the vehicle is switched to a state in which the seat 10 can move in the vehicle width direction. FIG. 3 is a plan view showing a state in which the seat 10 slides in the vehicle width direction, and FIG. 4 is a plan view showing that the seat 10 placed on the turntable 41A on the left side of the vehicle can be moved in the longitudinal direction of the vehicle. FIG. 5 is a plan view showing the structure of an interlocking mechanism for interlocking the respective rotating disks 41A and 41B, and FIG. 6 is a structure of the interlocking mechanism for interlocking the respective rotating disks 41A and 41B. FIG. 1 to 5, the left direction in the drawing is represented as the front direction of the vehicle.

The vehicle seat moving apparatus of this embodiment includes front and rear lower rails 20A and 20B for sliding the seat 10 applied as a rear seat of the vehicle in the front and rear direction of the vehicle, as well shown in FIG. A slide lock mechanism in the front-rear direction and a slide mechanism in the vehicle width direction including a lower rail 30 in the vehicle width direction for sliding the seat 10 in the vehicle width direction are configured. The front-rear direction lower rail 20A and the front-rear direction lower rail 20B have substantially the same configuration.
The former slide lock mechanism is disposed on a vehicle left seat (not shown) and a vehicle right seat 10 that are arranged in the vehicle width direction as rear seats of the vehicle. More specifically, a front-rear front-rear lower rail 20A and a front-rear front-rear lower rail 20B formed in a shape extending in the front-rear direction of the vehicle are arranged side by side in the vehicle width direction with respect to the vehicle floor. . The slide lock mechanism is fixed to the front and rear lower rails 20A and 20B fixed to the vehicle floor side and fixed to the seat 10 side so as to have sufficient strength that an occupant may sit on the seat 10 while the vehicle is traveling. The above-described upper rail 14 (see FIG. 6) is configured to be well-known to be slidably locked in the seating use area of the seat 10.
As shown in FIG. 1, the latter sliding mechanism in the vehicle width direction is disposed between the front and rear lower rail 20A on the left side of the vehicle and the front and rear lower rail 20B on the right side of the vehicle. The slide mechanism in the vehicle width direction is disposed on the vehicle floor surface F independently of the slide lock mechanism. Specifically, the lower rail 30 in the vehicle width direction formed as a shape extending in the vehicle width direction with respect to the vehicle floor is disposed at a position where the longitudinal sliding position of the seat 10 is the rearmost end. The lower rail 30 in the vehicle width direction is arranged so that the seat 10 can be moved between the front and rear lower rail 20B on the right side of the vehicle and the front and rear lower rail 20A on the left side of the vehicle, and at least a seat on which no occupant is seated. The structure is simple enough to be sufficient to support 10.
Further, at the rear ends of the lower rails 20A and 20B in the front-rear direction, conversion mechanisms 40A and 40B for switching the sliding movement of the seat 10 between the lower rails 20A and 20B in the front-rear direction and the lower rail 30 in the vehicle width direction. Is installed. As shown well in FIG. 6, these conversion mechanisms 40A and 40B have rotating disks 41A and 41B installed embedded in the vehicle floor, and the sliding movement of the seat 10 by the rotational movement of these rotating disks 41A and 41B. It is configured to change direction.
Hereafter, each said structure is demonstrated in detail.

First, the configuration of the sheet 10 will be described. As shown well in FIG. 1, the seat 10 includes a tip-up mechanism (not shown) that can hold the seat cushion 11 in a state in which the seat cushion 11 is flipped up and rotated toward the seat back 12 side. Accordingly, the seat 10 can be slid on the lower rail 20B in the front-rear direction with the seat 10 in the tip-up state. Note that the configuration of the tip-up mechanism is a known one, and a detailed description thereof will be omitted.
As well shown in FIG. 6, support members 13 that support the seat 10 with respect to the vehicle floor are provided at the left and right lower portions of the seat 10. The support member 13 integrally has an upper rail 14 that allows the seat 10 to be slide-locked with respect to the lower rails 20A and 20B in the front-rear direction. The upper rail 14 is formed with a predetermined width in the front-rear direction, and is assembled so as to be slidable with respect to the lower rail 20B in the front-rear direction. Further, the upper rail 14 is configured to be slide-locked with the lower rail 20B in the front-rear direction when the seat 10 is in the seating use area. A configuration of a lock mechanism (not shown) for slidingly locking the upper rail 14 and the front and rear lower rail 20B includes, for example, a configuration in which both are meshed with meshing teeth. Therefore, detailed description is omitted.

  Next, the front and rear lower rails 20A and 20B are arranged in a state of being embedded in the vehicle floor so that the upper surface thereof is flush with the vehicle floor surface F as well shown in FIG. That is, the lower rails 20A and 20B in the front-rear direction are formed in a shape that does not substantially protrude from the vehicle floor surface F. As well shown in FIG. 1, the rear end portions of the lower rails 20A and 20B in the front-rear direction are formed in a shape cut into an arc shape so as to connect the lower rail members 42A and 42B, which will be described later, and the movement path. .

  Next, as shown in FIG. 6, the lower rail 30 in the vehicle width direction is similar to the lower rails 20A and 20B in the front-rear direction described above so that the upper surface thereof is flush with the vehicle floor surface F. It is arrange | positioned as the state embedded in. That is, the lower rail 30 in the vehicle width direction is formed in a shape that does not substantially protrude from the vehicle floor surface F. Further, as well shown in FIG. 1, both end portions of the lower rail 30 in the vehicle width direction are formed in a shape cut into an arc shape so as to connect lower rail members 42A and 42B, which will be described later, and a moving path. The lower rail 30 in the vehicle width direction is formed in a shape that allows the upper rail 14 (see FIG. 6) to be slidably engaged along the longitudinal direction (vehicle width direction).

Next, as well shown in FIG. 6, the conversion mechanisms 40A and 40B include rotating boards 41A and 41B installed embedded in the vehicle floor, and lower rail members 42A installed on the rotating boards 41A and 41B. 42B and an interlocking mechanism for interlockingly rotating the two turntables 41A and 41B.
Specifically, the turntables 41A and 41B are supported by the turntable shafts 43A and 43B provided at the center thereof so as to be relatively rotatable with respect to the vehicle floor. Next, the lower rail members 42A and 42B are fixedly disposed on the respective rotating disks 41A and 41B. These lower rail members 42A and 42B are directed toward the lower rails 20A and 20B in the front-rear direction by the rotational movement of the respective rotating disks 41A and 41B (see FIG. 6), as well shown in FIGS. (See FIG. 1) and a state directed to the side of the lower rail 30 in the vehicle width direction (see FIG. 3). Specifically, the lower rail members 42A and 42B have arcs whose longitudinal ends match the shapes of the rear ends of the lower rails 20A and 20B in the front-rear direction and the shapes of both ends of the lower rail 30 in the vehicle width direction. It is formed into a shape. As shown in FIG. 6, the lower rail members 42A, 42B are slidably movable along the longitudinal direction of the upper rail 14 in the same manner as the lower rails 20A, 20B in the front-rear direction and the lower rail 30 in the vehicle width direction. It is formed in a shape that can be combined, and is arranged in a state of being embedded in the vehicle floor so that the upper surface thereof is flush with the vehicle floor surface F. Therefore, by rotating the turntables 41A and 41B, the movement path of the lower rail members 42A and 42B is connected to the lower rails 20A and 20B in the front-rear direction (see FIG. 1) and connected to the lower rail 30 in the vehicle width direction. The state can be switched to the state (see FIG. 3).
Accordingly, as well shown in FIG. 1, the seat 10 is disposed on the lower rail member 42B (on the turntable 41B) by sliding the seat 10 on the lower rail 20B in the front-rear direction toward the rear of the vehicle. (See FIG. 2). As shown well in FIG. 2, with the seat 10 placed on the lower rail member 42B, the rotating disk 41B is rotated in the clockwise direction, so that the movement path of the lower rail members 42A and 42B is changed to the vehicle width. It can be connected to the lower rail 30 in the direction. As a result, the seat 10 is slidable in the vehicle width direction. That is, by the rotational movement of the turntable 41B, the sliding movement direction of the seat 10 can be changed from the front-rear direction of the vehicle to the vehicle width direction.
Further, as well shown in FIG. 3, in a state where the moving path of the lower rail members 42A and 42B is connected to the lower rail 30 in the vehicle width direction, the seat 10 on the lower rail 30 in the vehicle width direction is moved in the vehicle width direction (same figure). Then, the seat 10 can be disposed on the lower rail member 42A (on the turntable 41A) by sliding it toward the left of the vehicle (see FIG. 4). Then, as shown well in FIG. 4, with the seat 10 placed on the lower rail member 42A, the turntable 41A is rotated in the counterclockwise direction, thereby moving the lower rail members 42A and 42B along the moving path. It can be connected to the lower rail 20A, 20B in the direction. As a result, the seat 10 is slidable in the front-rear direction. That is, by the rotational movement of the turntable 41A, the sliding movement direction of the seat 10 can be changed from the vehicle width direction to the vehicle front-rear direction.

  Next, as well shown in FIGS. 5 and 6, the interlocking mechanism includes shafts 44A and 44B arranged in parallel with the rotating disk shafts 43A and 43B, and the rotating disk shafts 43A and 43B and the shafts 44A and 44B. Belts 46A and 46B that are wound around each other and transmit both rotational forces, and gears 45A and 45B that are provided on the shafts 44A and 44B and are engaged with each other. According to this interlocking mechanism, the rotational force of the rotating disk 41A and the rotating disk 41B can be transmitted to both, so that the rotation of both the rotating disks 41A and 41B can be performed in an interlocked manner. Specifically, as well shown in FIG. 5, when the turntable 41B rotates counterclockwise, the turntable 41A rotates clockwise in conjunction with this. As a result, the lower rail members 42A and 42B were simultaneously connected to the lower rail 30 in the vehicle width direction from the state connected to the lower rails 20A and 20B in the front-rear direction (the state indicated by the solid line in the figure). It is possible to switch to a state (a state indicated by a virtual line in the figure). When the turntable 41B rotates in the clockwise direction, the turntable 41A rotates in the counterclockwise direction in conjunction with this. As a result, the lower rail members 42A and 42B are connected to the lower rails 20A and 20B in the front-rear direction from the state where they are connected to the lower rail 30 in the vehicle width direction (the state indicated by the phantom lines in the figure). The state can be switched to the state shown by the solid line in FIG.

Then, the usage method of the moving apparatus of the vehicle seat of a present Example is demonstrated. Here, as well shown in FIG. 1, a method of moving the seat 10 on the lower rail 20B on the right side of the vehicle onto the lower rail 20A on the left side of the vehicle will be described. When the seat 10 is slidable in the vehicle front-rear direction on the front-rear lower rail 20B, the lower rail members 42A, 42B are connected to the front-rear lower rails 20A, 20B.
First, as well shown in FIG. 1, the seat 10 on the lower rail 20B in the front-rear direction is slid to the end position. As a result, the seat 10 is disposed on the lower rail member 42B as well shown in FIG. Then, with the seat 10 placed on the lower rail member 42B, the turntable 41B is rotated counterclockwise. As a result, the movement path of the lower rail members 42A and 42B is connected to the lower rail 30 in the vehicle width direction, and the seat 10 is slidably movable in the vehicle width direction (the state shown by the solid line in the figure). That is, the sliding movement direction of the seat 10 is changed from the front-rear direction of the vehicle to the vehicle width direction.
Next, as well shown in FIG. 3, the seat 10 is slid in the vehicle width direction along the lower rail 30 in the vehicle width direction and disposed on the lower rail member 42 </ b> A. Then, as well shown in FIG. 4, with the seat 10 placed on the lower rail member 42A, the turntable 41A is rotated counterclockwise. As a result, the movement path of the lower rail members 42A and 42B is connected to the lower rails 20A and 20B in the front-rear direction, and the seat 10 is slidable in the front-rear direction (a state indicated by a solid line in the figure). That is, the sliding movement direction of the seat 10 is changed from the vehicle width direction to the vehicle front-rear direction.
In addition, when the seat (not shown) on the left and right lower rail 20A on the left side of the vehicle is moved onto the front and rear lower rail 20B on the right side of the vehicle, the same method as described above can be used.

  As described above, according to the vehicle seat moving device of the present embodiment, the conversion mechanism 40A, which includes the lower rail 30 in the vehicle width direction and the rotating disks 41A, 41B with a relatively simple configuration, compared to the known slide lock mechanism. With a simple configuration in which only 40B is provided, the degree of freedom of seat arrangement of the vehicle seat can be improved. In this embodiment, the seat 10 is slid in the tip-up state in order to secure a large cargo space. However, the seat 10 can be moved in the longitudinal direction of the vehicle without changing the posture state. It can be slid in the vehicle width direction. Therefore, such an operation can be easily performed. Furthermore, since the slide position that allows the seat 10 to move in the vehicle width direction is set at the rear end of the lower rails 20A and 20B in the front-rear direction, it becomes easy to distinguish the slide position from the seating use area of the seat 10, The ease of use can be improved by improving the sense of moderation of the seat slide. Furthermore, the lower rail members 42A and 42B always keep the seat 10 engaged with the lower rails 20A and 20B in the front-rear direction, the lower rail 30 in the vehicle width direction, and the lower rail members 42A and 42B. Conversion can be performed smoothly. Furthermore, since each of the turntables 41A and 41B can be rotated in an interlocking manner, a movement path of the seat 10 to be moved in the vehicle width direction can always be secured, and the use operability of the seat slide can be further improved. Further, since the lower rails 20A and 20B in the front-rear direction, the lower rail 30 in the vehicle width direction, and the lower rail members 42A and 42B are formed in a shape that does not substantially protrude from the vehicle floor surface F, the seat 10 is moved in the vehicle front-rear direction. Even if it is made to move in the vehicle width direction, the cargo compartment function of the vehicle floor surface F can be satisfactorily exhibited. Furthermore, since the seat 10 is not fixed (slide-locked) at an unexpected position when moving in the vehicle width direction, the seat 10 can be prevented from being used at an unexpected position.

Although the embodiment of the present invention has been described with one example, the present invention can be implemented in various forms in addition to the above example.
For example, the position where the seat movement direction can be switched is not necessarily the rearmost position of the slide position in the front-rear direction, and may be set to a position in the middle of the slide area. However, it should be noted that in this case, for example, it may be difficult to distinguish the switching position from the seating use area of the seat, or the moderation feeling of the seat slide may be lost.
Moreover, the structure installed in the vehicle floor side, such as the front-rear direction lower rail, the vehicle width direction lower rail, and the lower rail member, may be configured to protrude from the vehicle floor surface. However, in this case, the cargo compartment function on the vehicle floor surface may be impaired.
Moreover, it is good also as a structure which mounts a sheet | seat directly on a turntable, and a structure without a lower rail member. However, in this case, since the engagement state between the upper rail and the lower rail is released when the seat is placed on the turntable, the direction of movement may not be changed smoothly. is necessary.
Moreover, you may set so that each turntable may rotate interlockingly in the same direction. In addition, the lower rail member has an arc shape so that the end shape connected to the lower rail in the front-rear direction and the lower rail in the vehicle width direction matches the end shape (concave arc shape) of each lower rail by the rotation of the rotating disk. It may be formed. That is, the connection shape with each lower rail as shown in the above embodiment may be formed in each end shape of the lower rail member. By combining these configurations, for example, the seat can be slid in the front-rear direction with the front of the vehicle facing even on the lower rail after movement.
Further, an appropriate locking means may be provided so that the rotating disk is fixed at the position shown in FIG. 1 or FIG. Thereby, the change of a moving direction can be performed more smoothly.
