Description

[Technical Field]

[0001] The present invention relates to a vehicle seat device in which a seat body is rotated by a seat moving mechanism from a seating position facing forward of the vehicle to a sideways position facing a door opening, and further moved to an entry / exit position outside the door opening. [Background technology]

[0002] Patent Document 1 describes a technology related to a vehicle seat device. As shown in FIGS. 16 and 17 , the vehicle seat device 100 described in Patent Document 1 includes a longitudinal slide mechanism 101 installed on a floor panel F of a vehicle interior. A rotation mechanism 103 that horizontally rotates a seat body 105 is provided on the longitudinal slide mechanism 101. Furthermore, a lifting and lowering slide mechanism 104 that slides the seat body 105 to the outside of a door opening D to raise and lower the seat body 105 is provided on the rotation mechanism 103. The seat body 105 is installed on the lifting and lowering slide mechanism 104.

[0003] Furthermore, the vehicle seat device 100 includes a control device (not shown) that operates the longitudinal slide mechanism 101, the rotation mechanism 103, and the lifting and lowering slide mechanism 104. When moving the seat body 105 to the entry / exit position, the control device first rotates the seat body 105 toward the door opening D while moving it forward using the longitudinal slide mechanism 101 and the rotation mechanism 103. Next, midway through the rotation of the seat body 105, the control device operates the lifting and lowering slide mechanism 104 from a state in which the leading end of the seat body 105 is closest to a front pillar 108 (see FIG. 17 ) to start the downward sliding of the seat body 105. In other words, because the lifting and lowering slide mechanism 104 starts the downward sliding of the seat body 105 midway through the rotation of the seat body 105, the time required to move the seat body 105 to the entry / exit position can be shortened. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-3997 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the vehicle seat device 100 described in Patent Document 1, the movement route of the seat main body 105 is exactly the same whether or not an occupant is seated in the seat main body 105. However, when no occupant is seated in the seat main body 105, there is room to shorten the movement time of the seat main body 105 by shortening the route compared to the normal movement route.

[0006] The present invention has been made to solve the above problems, and the problem that the present invention aims to solve is to make it possible to move the seat body between the seating position and the boarding / exiting position in a shorter time when there is no occupant seated in the seat body than when there is an occupant seated in the seat body. [Means for solving the problem]

[0007] The above-mentioned problems are solved by the following inventions. A first invention is a vehicle seat device that rotates a seat body from a seating position facing forward of the vehicle to a sideways position facing a door opening side, and further moves the seat body to a boarding / exiting position outside the door opening, the vehicle seat device comprising: seat occupancy detection means that detects the presence or absence of an occupant in the seat body; a first program that moves the seat body along the shortest route between the seating position and the boarding / exiting position; and a second program that moves the seat body along a normal route that is longer than the shortest route; and a control device that operates the seat moving mechanism based on the first program or the second program, wherein if the seat occupancy detection means does not detect an occupant, the control device operates the seat moving mechanism based on the first program, and if the seat occupancy detection means detects an occupant, the control device operates the seat moving mechanism based on the second program.

[0008] According to the present invention, when the seat occupancy detection means does not detect an occupant, the control device operates the seat moving mechanism based on a first program with the shortest route. Furthermore, when the seat occupancy detection means detects an occupant, the control device operates the seat moving mechanism based on a second program with a normal route that is longer than the shortest route. Therefore, when no occupant is seated in the seat body, the seat moving mechanism can move the seat body between the seating position and the boarding / alighting position via the shortest route. Therefore, when no occupant is seated in the seat body, the seat body can be moved between the seating position and the boarding / alighting position in a shorter time than when an occupant is seated in the seat body.

[0009] According to a second aspect of the present invention, the seat movement mechanism includes a longitudinal slide base that slides the seat body in the longitudinal direction of the vehicle, and a rotation mechanism that rotates the seat body on the longitudinal slide base from a seating position facing the front of the vehicle to a sideways position facing the door opening, and the longitudinal slide base slides forward while the seat body is rotated by the rotation mechanism, causing the seat body to move while avoiding obstacles, and the first program moves the seat body closer to the obstacle than the second program, thereby making the movement route of the seat body the shortest route. In other words, when no occupant is seated in the seat body, there is no need to consider interference between the occupant and the obstacle, and no problem occurs even if the seat body moves close to the obstacle.

[0010] According to the third aspect of the present invention, the seat moving mechanism includes a reclining mechanism that tilts the seat back relative to the seat cushion of the seat body, and the first program omits the operation of the reclining mechanism. This means that the seat body does not recline when no passenger is seated in the seat body, and the sequence of operations of the seat moving mechanism is not delayed by the reclining operation.

[0011] According to a fourth aspect of the present invention, when the seat occupancy detection means detects an occupant and the second program is being executed, the control device switches the second program to the first program if the seat occupancy detection means no longer detects an occupant. Therefore, if the occupant gets off the seat body before the seat body moves to the entry / exit position, the control device switches from the second program to the first program. [Effects of the Invention]

[0012] According to the present invention, when no occupant is seated on the seat body, the seat body can be moved between the seating position and the getting-in / out position in a shorter time than when an occupant is seated on the seat body. [Brief explanation of the drawings]

[0014] [Embodiment 1] A vehicle seat device according to a first embodiment of the present invention will be described below with reference to Fig. 1 to Fig. 15. The vehicle seat device 10 according to this embodiment is a seat device used as a passenger seat in a vehicle compartment R. Here, front, rear, left, right, top and bottom in the drawings correspond to front, rear, left, right, top and bottom of a vehicle equipped with the vehicle seat device 10 according to this embodiment.

[0015] <Overview of the Vehicle Seat Device 10> The vehicle seat device 10 includes a seat body 12 on which an occupant sits, and a seat movement mechanism 20 that moves the seat body 12 from a seating position inside the vehicle compartment R to a boarding and disembarking position outside the vehicle compartment R. As shown in the schematic side views of FIGS. 2 to 5, the seat movement mechanism 20 includes a front-rear slide mechanism 30 installed on a floor panel F of the vehicle compartment R, and a rotation mechanism 40 installed on a front-rear slide base 35 of the front-rear slide mechanism 30. The rotation mechanism 40 is a mechanism that rotates the seat body 12 from a seating position facing forward of the vehicle to a sideways position facing the door opening D.

[0016] As shown in FIG. 4 and other figures, the seat moving mechanism 20 is provided on the rotary table 45 of the rotation mechanism 40 with an external slide mechanism 70 that slides the seat body 12 outward from the door opening D, and an external lifting mechanism 60 (see FIG. 5) that raises and lowers the seat body 12 outside the vehicle compartment R. The seat body 12 is provided with a reclining mechanism 80 (see FIG. 8) that tilts the seat back 12b relative to the seat cushion 12c. As shown in FIG. 7, a seating sensor 50 that can detect the seating of an occupant is attached to the seat cushion 12c of the seat body 12. Furthermore, as shown in FIG. 9, the vehicle seat device 10 is provided with an ECU that is a control device that operates the motors M1 to M5 of the forward / backward slide mechanism 30, the rotation mechanism 40, the external lifting mechanism 60, the external slide mechanism 70, and the reclining mechanism 80 based on a signal from the seating sensor 50.

[0017] <Regarding the front-rear slide mechanism 30> The longitudinal sliding mechanism 30 is a mechanism for moving the seat body 12 in the longitudinal direction of the vehicle within the vehicle compartment R. As shown in FIGS. 2 and 3 , the longitudinal sliding mechanism 30 includes a fixed base 31 installed on the floor panel F and a pair of left and right fixed rails 33 attached to the fixed base 31 so as to extend in the longitudinal direction of the vehicle. As shown in FIG. 3 and other figures, the pair of left and right fixed rails 33 support left and right sliders 35s of a longitudinal sliding base 35 in a longitudinally slidable state. The longitudinal sliding mechanism 30 includes a motor M2 that slides the longitudinal sliding base 35 longitudinally along the fixed rails 33, and a drive mechanism 37.

[0018] <About the rotation mechanism 40> The rotation mechanism 40 is a mechanism that horizontally rotates the seat body 12 by approximately 100° from a seating position facing forward of the vehicle to a sideways position facing the door opening D. As shown in Figures 2 and 3, the rotation mechanism 40 includes an inner ring 41 fixed on the front-rear slide base 35 so that its axis is vertical, and an outer ring 43 that is rotatably connected coaxially to the inner ring 41, and the upper surface of the outer ring 43 is fixed to a rotary table 45. The rotation mechanism 40 includes a motor M1 that rotates the outer ring 43 coaxially with respect to the inner ring 41, and a drive mechanism (not shown).

[0019] <Regarding the external lifting mechanism 60> 4 and 5, the external lifting mechanism 60 is a mechanism that lifts and lowers the seat body 12 outside the vehicle compartment R. The external lifting mechanism 60 includes a lateral slide base 62 configured to be slidable in the front-to-rear direction of the seat body 12 on the rotary table 45, a four-bar link mechanism 64 whose base end is connected to the lateral slide base 62, and a lifting base 65 connected to the tip end of the four-bar link mechanism 64. The seat body 12 is supported on the lifting base 65 via an external slide mechanism 70.

[0020] In the external lifting mechanism 60, as shown in Fig. 5, in the process of the lateral slide base 62 sliding forward from the rear end position to the front end position of the rotary table 45, the four-bar link mechanism 64 rotates downward due to the weight of the seat body 12 and the like, and the lifting base 65 supporting the seat body 12 and the like descends while moving forward. In addition, as the lateral slide base 62 slides backward from the front end position to the rear end position of the rotary table 45, the four-bar link mechanism 64 rotates upward, and the lifting base 65 supporting the seat body 12 and the like ascends while moving backward. As shown in the rear view of Fig. 6, the external lifting mechanism 60 includes a motor M5 and a drive mechanism 68 for sliding the lateral slide base 62 back and forth relative to the rotary table 45.

[0021] <About the outer slide mechanism 70> As shown in Figs. 3 and 4, the external slide mechanism 70 is a mechanism for sliding the seat body 12 on the rotary table 45 (on the lifting base 65) to the outside of the door opening D. As shown in Figs. 4 to 6, the external slide mechanism 70 is provided with a seat base 72 that supports the seat body 12. The seat base 72 is configured to be able to slide in the front-to-rear direction of the seat body 12 relative to the lifting base 65 of the external lifting mechanism 60. As shown in Fig. 6, the external slide mechanism 70 is provided with a motor M3 and a drive mechanism 75 for sliding the seat base 72 back and forth relative to the lifting base 65.

[0022] <About the seat body 12> As shown in FIGS. 1 to 5, the seat main body 12 includes a seat cushion 12c, a seat back 12b, and a reclining mechanism 80 (see FIG. 8). The frame of the seat cushion 12c is fixed to the seat base 72 of the outer slide mechanism 70. As shown in FIG. 7, a seating sensor 50 is attached to the cushion pad of the seat cushion 12c at the seating position of the occupant, and the cushion pad is covered with a cover. As shown in FIGS. 4 and 5, a footrest 12f is attached to the frame of the seat cushion 12c. The reclining mechanism 80 changes the tilt angle of the seat back 12b relative to the seat cushion 12c, and as shown in FIG. 8, includes a motor M4 and a drive mechanism 85 including an internal gear 85e, an external gear 85p, etc.

[0023] <ECUについて> The ECU controls the motors M1 to M5 of the seat movement mechanism 20 to move the seat body 12 between a seating position within the vehicle interior R and a boarding / boarding position outside the vehicle interior R based on the occupant's boarding or boarding operation. As shown in FIG. 9, an exit signal or an entry signal can be input to the ECU from a remote control or a fixed operation switch (not shown). The ECU detects the presence or absence of an occupant in the seat body 12 using the seating sensor 50, and if there is no occupant, drives the motors M1 to M5 based on a first program (see FIG. 11). If there is an occupant, drives the motors M1 to M5 based on a second program (see FIG. 10). Furthermore, while the exit signal or entry signal is continuously input, the ECU operates the motors M1 to M5 based on the first program or the second program. Furthermore, when the input of the dismounting signal or the boarding signal is stopped, the ECU stops the motors M1 to M5 and interrupts the dismounting or boarding operation.

[0024] <Operation of the Vehicle Seat Device 10> When the seat body 12 is moved from a seating position inside the vehicle compartment R (see FIGS. 2, 12, etc.) to a boarding / exiting position outside the vehicle compartment R (see FIG. 15), the vehicle door Dr is opened and then the exit switch is operated. If an occupant is seated in the seat body 12, the ECU receives a signal from the seating sensor 50 and drives the motors M1 to M5 based on the second program, as shown in FIG. 10. That is, first, at time t0, the motor M1 of the rotation mechanism 40 is operated, and the seat body 12 begins to rotate horizontally to the left toward the door opening D. Next, at time t1, the motor M4 of the reclining mechanism 80 of the seat body 12 is operated, and the seat back 12b is tilted backward to avoid interference between the occupant's head and the upper edge Da of the door opening D.

[0025] Next, at time t2, motor M2 of the longitudinal sliding mechanism 30 operates, causing the seat body 12 to slide forward. That is, the seat body 12 slides forward while rotating horizontally to the left, thereby avoiding interference between the seat body 12 and the occupant and the center pillar P of the vehicle (see FIGS. 12 and 13) during the rotation. Next, after motor M4 of the reclining mechanism 80 is stopped, motor M3 of the external sliding mechanism 70 operates at time t3 while the seat body 12 is rotating horizontally to the left, as shown in FIG. 10, causing the seat body 12 to slide outward (forward) relative to the lifting base 65 of the external lifting mechanism 60, as shown in FIGS. 3 and 4.

[0026] Next, at time t4 (see FIG. 10), the motor M1 of the rotation mechanism 40 and the motor M2 of the longitudinal sliding mechanism 30 are stopped (see the plan view of FIG. 14). Then, the motor M4 of the reclining mechanism 80 is operated again, and the seat back 12b is tilted further rearward. This ensures a space between the occupant's head and the upper edge Da of the door opening D when the seat body 12 slides outward. Then, at time t5, when the seat body 12 slides forward to near the forward limit position as shown in FIG. 4, the motor M5 of the external lifting mechanism 60 is driven. As a result, as shown in FIG. 5, the horizontal slide base 62 of the external lifting mechanism 60 slides forward on the rotary table 45 of the rotation mechanism 40 from the rear end position to the front end position, and the four-bar link mechanism 64 rotates downward, causing the seat body 12 to descend to the boarding / exiting position (see the plan view of FIG. 15). That is, the seat body 12 moves to the boarding / exiting position along the normal route II as shown in FIG. 15.

[0027] During the process (time t6) in which the external lifting mechanism 60 operates to lower the seat body 12 to the boarding / alighting position, the reclining mechanism 80 of the seat body 12 is driven in the original direction, i.e., in the forward tilting direction, for a certain period of time, as shown in Fig. 10. Then, at timing t7 when the seat body 12 reaches the boarding / alighting position, the reclining mechanism 80 operates in the forward tilting direction again and stops at time t8. This completes the series of operations for moving the seat body 12 from the seating position inside the vehicle interior R to the boarding / alighting position outside the vehicle interior R (see Fig. 15).

[0028] When the seat body 12 is moved from the boarding / alighting position outside the vehicle interior R to the seating position inside the vehicle interior R, the boarding switch is operated. This causes the ECU to operate the motors M1 to M5 of the longitudinal sliding mechanism 30, the rotation mechanism 40, the external lifting / lowering mechanism 60, the external sliding mechanism 70, and the reclining mechanism 80 of the seat body 12 in the reverse procedure of the above-mentioned disembarking procedure. This causes the seat body 12 to return from the boarding / alighting position outside the vehicle interior R to the seating position inside the vehicle interior R (see FIGS. 1, 2, and 9).

[0029] When no occupant is seated in the seat body 12, the ECU receives a signal from the seating sensor 50 and drives the motors M1 to M3 and M5 based on a first program, as shown in FIG. 11 . That is, first, at time t0, the motor M1 of the rotation mechanism 40 operates, and the seat body 12 begins to rotate horizontally to the left from the seating position toward the door opening D. Here, when no occupant is seated in the seat body 12, there is no need to consider interference between the occupant's head and the upper edge Da of the door opening D, and therefore operation of the reclining mechanism 80 is unnecessary. Next, at time t2, the motor M2 of the forward / backward sliding mechanism 30 operates, and the seat body 12 slides forward. When no occupant is seated in the seat body 12, it is sufficient to avoid interference between the rotating seat body 12 and the center pillar P of the vehicle as much as possible. That is, there is no need to consider interference between the occupant and the center pillar P. Therefore, the forward sliding amount of the longitudinal sliding mechanism 30 is the minimum necessary to avoid interference between the seat body 12 and the center pillar P. Therefore, the seat body 12 can be moved along the shortest route.

[0030] Next, while the seat body 12 is rotating horizontally to the left, as shown in FIG. 11, the motor M3 of the external slide mechanism 70 operates at time t3s, causing the seat body 12 to slide outward (forward) relative to the lifting base 65 of the external lifting mechanism 60, as shown in FIGS. 3 and 4. Here, the time t3s at which the external slide mechanism 70 starts operating is sufficiently earlier than the time t3 at which the external slide mechanism 70 starts operating based on the second program. Next, while the seat body 12 is sliding outward, the motor M1 of the rotation mechanism 40 and the motor M2 of the longitudinal slide mechanism 30 stop at time t4s (see FIG. 11), and the motor M5 of the external lifting mechanism 60 starts operating at time t5s. As a result, as shown in FIG. 5, the horizontal slide base 62 of the external lifting mechanism 60 slides forward on the rotary table 45 of the rotation mechanism 40 from the rear end position to the front end position, and the four-bar link mechanism 64 rotates downward, causing the seat body 12 to descend to the boarding / exiting position (time t6e). That is, the seat body 12 moves to the boarding and alighting position along the shortest route I as shown in FIG.

[0031] Here, time t5s when the external lifting mechanism 60 starts operating based on the first program is sufficiently earlier than time t5 (see FIG. 10) when the external lifting mechanism 60 starts operating based on the second program. Similarly, time t6e when the series of operations for moving the seat main body 12 to the boarding / exiting position based on the first program is completed is sufficiently earlier than times t7 and t8 when the series of operations for moving the seat main body 12 to the boarding / exiting position based on the second program are completed.

[0032] <Comparison between terms used in this embodiment and terms related to the present invention> The seating sensor 50 and the ECU in this embodiment correspond to the seating detection means of the present invention, the ECU corresponds to the control device of the present invention, and the center pillar P of the vehicle corresponds to the obstacle of the present invention.

[0033] <Advantages of the vehicle seat device 10 according to this embodiment> According to the vehicle seat device 10 of this embodiment, when the seating sensor 50 (seat occupancy detection means) does not detect an occupant, the ECU (controller) operates the seat moving mechanism 20 based on a first program of the shortest route I. Furthermore, when the seating sensor 50 detects an occupant, the ECU operates the seat moving mechanism 20 based on a second program of the normal route II, which is longer than the shortest route I. That is, when no occupant is seated in the seat main body 12, the seat moving mechanism 20 moves the seat main body 12 between the seating position and the ingress / egress position via the shortest route. Therefore, when no occupant is seated in the seat main body 12, the seat main body 12 can be moved between the seating position and the ingress / egress position in a shorter time than when an occupant is seated. Furthermore, when no occupant is seated in the seat main body 12, the seat main body 12 does not recline, so the sequence of operations of the seat moving mechanism 20 is not delayed by the reclining operation.

[0034] <Example of change> The present invention is not limited to the above-described embodiment, and modifications are possible within the scope of the present invention. For example, in the present embodiment, the seat main body 12 is moved between a seating position inside the vehicle interior R and an entry / exit position outside the vehicle interior R based on the first program or the second program of the ECU. However, for example, when the seat sensor 50 detects an occupant and the second program is being executed, the ECU can quickly switch the second program to the first program if the seat sensor 50 no longer detects an occupant. This allows the second program to be switched to the first program if the occupant gets out of the seat main body 12 before the seat main body 12 moves to the entry / exit position.

[0035] Furthermore, in this embodiment, the vehicle seat device 10 including the external lifting mechanism 60 has been exemplified, but the present invention can also be applied to a vehicle seat device that does not include the external lifting mechanism 60. [Explanation of symbols]
