The locking mechanism 80 includes a screw 82 (locking portion) that penetrates the cylindrical portion 66 in a direction perpendicular to the axis and engages with the shaft portion 70. When the screw 82 is rotated in the tightening direction, the screw 82 enters the inner hole of the cylindrical portion 66 and engages with the shaft portion 70, resulting in a restricted state in which rotation of the shaft portion 70 is restricted. When the screw 82 is loosened, the shaft portion 70 retreats from the inner hole of the cylindrical portion 66, and the shaft portion 70 is switched to a movable state in which rotation is possible. In this embodiment, the peripheral wall portion 53 is provided with a through hole 84 for operating the screw 82 from the outside.

Height control coupler 60B is a female connector (receptacle) connectable to height motor coupler 35B. The height control coupler 60B is fixed to the right surface of the main body 52 at approximately the center in the front-rear direction. The height control coupler 60B is connected to the height motor coupler 35B by being inserted from the right side (inside the seat).

More specifically, the height control coupler 60B is a panel mount type female connector (receptacle), and is housed inside the case 58B while being soldered to the circuit board 58A of the control device 58. A through hole 58C is provided on the inner surface of the seat of the case 58B at approximately the center in the front-rear direction, and the height control coupler 60B is arranged at a position aligned with the through hole 58C. By inserting the height motor coupler 35B into the case 58B through the through hole 58C, the height motor coupler 35B is fitted into the height control coupler 60B and electrically connected. When the side cover 33 is coupled to the left cushion side frame 15 from the outside of the seat (left side), the height control coupler 60B is connected to the height motor coupler 35B.

Tilt control coupler 60C is a female connector (receptacle) connectable to tilt motor coupler 35C. The tilt control coupler 60C is fixed to the front right side of the main body 52 of the side cover 33. The tilt control coupler 60C is connected to the tilt motor coupler 35C by being inserted from the right side (inside the seat).

More specifically, the tilt control coupler 60C is a panel mount type female connector (receptacle), and is housed inside the case 58B while being soldered to the circuit board 58A of the control device 58. A through hole 58D is provided at the front of the inner surface of the seat of the case 58B, and the tilt control coupler 60C is arranged at a position aligned with the through hole 58D. By inserting the tilt motor coupler 35C into the case 58B through the through hole 58D, the tilt motor coupler 35C is fitted into the tilt control coupler 60C and electrically connected. When the side cover 33 is coupled to the left cushion side frame 15 from the outside of the seat (left side), the tilt control coupler 60C is connected to the tilt motor coupler 35C.

Next, the effects of the vehicle seat 1 will be explained. As shown in FIG. 4, when assembling the vehicle seat 1, an operator first sets the rotating part 68 to the initial position and tightens the screw 82 to fix the rotating part 68 at the initial position. Next, the operator places the seat back 6 in the upright position, and then connects the side cover 33 to the left cushion side frame 15. At this time, a gap 55 is formed between the side cover 33 and the cushion side frame 15, and the control device 58 is accommodated in the gap 55. Furthermore, the REC control coupler 60A is coupled and electrically connected to the REC motor coupler 35A, the height control coupler 60B to the height motor coupler 35B, and the tilt control coupler 60C to the tilt motor coupler 35C. Thereby, the electrical operation unit 32 is electrically connected to the REC motor 34A, the height motor 34B, and the tilt motor 34C.

In this way, by attaching the side cover 33 to the cushion side frame 15, the control couplers 60 (REC control coupler 60A, height control coupler 60B, and tilt control coupler 60C) provided on the side cover 33 can be connected to the corresponding couplers. (REC motor coupler 35A, height motor coupler 35B, and tilt motor coupler 35C; hereinafter, seat body side coupler 35). In other words, the control coupler 60 is provided on the side cover 33 so as to be connected to the corresponding seat body side coupler 35. By coupling the side cover 33 to the cushion side frame 15, the control coupler 60 is connected to the corresponding seat body side coupler 35, and electrically connects each motor 34A, 34B, and 34C to the control device 58 and the operation switch 56. The connection is complete. Therefore, when installing the side cover 33, there is no need to route the wiring from the cushion side frame 15 or to fix the wiring to the side cover 33. This simplifies the process of assembling the side cover 33 and improves the ease of assembling the vehicle seat 1. Furthermore, by simplifying the process of assembling the side cover 33, the assembly of the side cover 33 can be automated.

Further, since the control device 58 is disposed in the gap 55 between the side cover 33 and the left cushion side frame 15, the control device 58 is difficult to be exposed from the outside. Thereby, the design of the vehicle seat 1 can be improved, and the control device 58 can be protected.

After attaching the side cover 33 to the left cushion side frame 15, the operator loosens the screws 82. This allows the shaft portion 70 to rotate relative to the cylindrical portion 66. Therefore, the rotating part 68 is rotatable about the tilting axis P, and the REC control coupler 60A coupled to the rotating part 68 is also rotatable about the tilting axis P.

When the occupant makes an input to the operation switch 56, the control device 58 controls the driving of each of the REC motor 34A, height motor 34B, and tilt motor 34C based on the input to the operation switch 56. Thereby, the tilt angle of the seat back 6, the height of the seat cushion 5, and the rotation angle of the seat cushion 5 can be changed by inputting information to the operation switch 56 by the occupant.

The seat back 6 rotates about the tilting axis P with respect to the seat cushion 5 by driving the REC motor 34A. At this time, the REC motor coupler 35A provided on the seat back 6 also rotates about the tilting axis P with respect to the seat cushion 5. In this embodiment, the REC control coupler 60A is coupled to a rotating part 68 that is rotatable about the tilting axis P. As a result, the REC control coupler 60A moves relative to the seat cushion 5 of the seat back 6 following the rotation. Therefore, when the seat back 6 rotates with respect to the seat cushion 5 around the tilting axis P, the relative positions of the REC motor coupler 35A and the REC control coupler 60A do not change. Therefore, separation of the REC motor coupler 35A and the REC control coupler 60A is prevented, and the electrical connection between the REC motor coupler 35A and the REC control coupler 60A is maintained.

On the other hand, when attaching the side cover 33 to the cushion side frame 15, the rotation of the shaft portion 70 is locked by the screw 82. Thereby, when attaching the side cover 33, the rotating part 68 does not rotate, and the REC control coupler 60A can be maintained at the initial position aligned with the REC motor coupler 35A. Therefore, when attaching the side cover 33, the REC control coupler 60A can be easily coupled to the REC motor coupler 35A, and the vehicle seat 1 can be easily assembled.

As shown in FIG. 1, the operation switch 56 is provided on the side cover 33 arranged on the side of the seat cushion 5. Thereby, the operation switch 56 can be placed near the hand of the person sitting on the vehicle seat 1, so that the person sitting on the vehicle seat 1 can easily operate the operation switch 56.

As shown in FIG. 3, the control device 58 and the operation switch 56 are coupled to the inner surface of the seat of the side cover 33. By consolidating the control device 58 and the operation switch 56 on the side cover 33 in this way, the operation switch 56 and the control device 58 can be placed closer to each other than, for example, when the control device 58 is provided on the lower surface of the seat cushion 5. The length of the wiring connecting the two can be shortened. This can reduce the possibility that the wiring will be caught on the frame of the seat cushion 5 or the like during assembly work. Furthermore, since the length of the wiring can be shortened, manufacturing costs can be reduced.

The height motor coupler 35B and the tilt motor coupler 35C are connected to the corresponding height control coupler 60B and tilt control coupler 60C by being inserted into the case 58B, respectively. Therefore, after the side cover 33 is assembled, the tip ends of the height motor coupler 35B and the tilt motor coupler 35C are respectively housed inside the case 58B and are not exposed to the outside. Therefore, the height motor coupler 35B and the tilt motor coupler 35C can be protected from loads from the outside world.

Thereby, the REC motor 34A rotates the seat cushion 5 about the tilting axis P, and tilts the seat back 6 with respect to the seat cushion 5.

The height motor 34B is coupled to the rear portion of the right side (ie, inner surface) of the main body 52 of the main side cover 102. When the main side cover 102 is attached to the cushion side frame 15, the height motor 34B is accommodated in the gap 55 formed between the main body 52 of the main side cover 102 and the cushion side frame 15. At this time, the output shaft 110B of the height motor 34B protrudes rightward and is coupled to a shaft joint 114B of a driven shaft 112B (driven portion) rotatably supported by the cushion frame 12. By rotating the output shaft 110B, the height motor 34B rotates the driven shaft 112B and rotates each of the parallel links 46 that form a pair of front and rear pairs. Thereby, the seat cushion 5 moves up and down with respect to the floor 4 according to the drive of the height motor 34B.

The tilt motor 34C is coupled to the front portion of the right side (ie, inner surface) of the main body 52 of the main side cover 102. When the main side cover 102 is attached to the cushion side frame 15, the tilt motor 34C is also accommodated in the gap 55 formed between the main body 52 of the main side cover 102 and the cushion side frame 15. At this time, the output shaft 110C of the tilt motor 34C protrudes to the right and is coupled to a shaft joint 114C of a driven shaft 112C (driven component) rotatably supported by the cushion frame 12. By rotating the output shaft 110C, the tilt motor 34C rotates the driven shaft 112C and rotates the front parallel link 46. Thereby, the seat cushion 5 rotates about a rotation axis extending in the left-right direction passing through the rear portion, and the inclination angle of the seating surface 9 with respect to the floor 4 is changed.

The REC motor 34A, the height motor 34B, and the tilt motor 34C are each connected to the electrical operation unit 32 via a cable 116. It is preferable that the cables 116 connecting the motors 34A, 34B, and 34C to the electrical operation unit 32 are latched to appropriate positions on the main side cover 102 and the auxiliary side cover 103, respectively.

Furthermore, the cushion side frame 15 is provided with a through hole 118 that penetrates in the vehicle width direction approximately at the center.

The power receiving coupler 122 is a male connector that is detachable from the power feeding coupler 120 and is connected to the electrical operation unit 32 . In this embodiment, the power receiving coupler 122 is housed in the case of the control device 58. The case 58B has a substantially rectangular parallelepiped shape extending in the front-rear direction. A circuit board 58A on which a CPU and memory are mounted is housed inside the case 58B so as to face in the left-right direction. The power receiving coupler 122 is coupled to the sheet inner surface (right surface) of the circuit board 58A, and a through hole 58E is provided on the right side surface of the case 58B at a position aligned with the power receiving coupler 122. When the power feeding coupler 120 is inserted into the case 58B through the through hole 58E, it fits into the power receiving coupler 122 and is electrically connected. As a result, power is supplied to the electrical operation unit 32 from the on-vehicle battery via the power feeding coupler 120 and the power receiving coupler 122. The electrical operation unit 32 supplies electric power to each motor 34A, 34B, and 34C according to the input to the operation switch 56, and controls the drive of each motor 34A, 34B, and 34C.

The lower end of the auxiliary side cover 103 is located above the rear of the main side cover 102. As shown in FIG. 7, in this embodiment, the peripheral edge portion 105 has a band shape extending from the front edge, upper edge, and rear edge of the main body portion 104 toward the inside (right side) of the seat. At the lower end of the auxiliary side cover 103, an extending portion 130 is provided that projects downward from the lower edge of the main body portion 104.

A step portion 132 is formed at the rear upper edge of the main side cover 102 and is recessed toward the vehicle inner side when viewed in the front-rear direction. The extending portion 130 is pivotally supported by the stepped portion 132 so as to be rotatable about the tilting axis P. As a result, the auxiliary side cover 103 and the main side cover 102 are rotatably coupled and integrated.

More specifically, the extending portion 130 has a plate shape facing in the left-right direction. The lower edge 130A of the extending portion 130 has an arc shape when viewed from the side. As a result, the lower end of the extending portion 130 is formed with an extended lower end surface 134 that has a substantially arc shape when viewed from the side and projects downward. A front edge and a lower edge of the extending lower end surface 134 are continuously connected to the front and rear surfaces of the peripheral edge portion 105 extending substantially in the vertical direction, respectively.

The first surface 138 extends downward from the upper edge of the main side cover 102. The second surface 140 extends from the rear front edge of the main side cover 102 to the rear edge. The extending portion 130 is disposed on the right side so as to contact the first surface 138 of the stepped portion 132 from the left side, and the extending portion 130 is rotatably supported by the first surface 138 of the stepped portion 132 .

In this embodiment, as shown in FIG. 8, the second surface 140 has a downwardly concave arc shape when viewed from the side. The radius of curvature (R _a ) of the second surface 140 is larger than the radius of curvature (R _b ) of the extending lower end surface 134 in a side view.

Next, the effects of the vehicle seat 101 according to this embodiment will be explained. By connecting the main side cover 102 to the cushion side frame 15 and the auxiliary side cover 103 to the back side frame 25, the output shafts 110A to 110C of each motor 34A to 34C are connected to the corresponding shaft joints 114A to 114C, respectively. Connected. This allows the power of each motor 34A to 34C to be transmitted to the corresponding driven shaft 112A to 112C (driven parts). In this way, by providing each of the motors 34A to 34C to the main side cover 102 and the auxiliary side cover 103, each motor 34A to 34C, the main side cover 102, and the auxiliary side cover 103 are integrated into one unit 142. (module) is configured. By assembling the configured unit 142 to the cushion side frame 15 and the back side frame 25, the driving force of each motor 34A to 34C can be transmitted to the corresponding driven shaft 112A to 112C. This completes the assembly of the motors 34A to 34C to the vehicle seat 101. Therefore, there is no need to assemble the motors 34A to 34C inside or under the seat cushion 5 or seat back 6, respectively, and the motors 34A to 34C can be easily assembled.

Furthermore, the airbag module 108 is also integrated with the auxiliary side cover 103 to form one unit 142 (module). By attaching the unit 142 to the backside frame 25, the vehicle seat 1 can be provided with a side airbag. As a result, the side airbag can be provided without requiring the step of providing the airbag module 108 inside or on the lower surface of the seatback 6, making it easier to assemble the airbag.

Although the description of the specific embodiments has been completed above, the present invention is not limited to the above-mentioned embodiments and can be widely modified and implemented. In the embodiment described above, the REC motor coupler 35A is provided on the backside frame 25, but the embodiment is not limited to this embodiment. The REC motor coupler 35A may be provided on the left cushion side frame 15.

In the embodiment described above, the rotary part 68 includes the shaft part 70 having a shaft shape, and the support part 64 includes the cylinder part 66 that receives the shaft part 70, but the present invention is not limited to this embodiment. For example, the support portion 64 may include the shaft portion 70, and the rotating portion 68 may include the cylinder portion 66 that receives the shaft portion 70.

In the first embodiment, the shaft joints 114A to 114C are provided on the driven shafts 112A to 112C, respectively, but the invention is not limited to this embodiment. Shaft joints 114A-114C may be provided on output shafts 110A-110C, respectively. Further, in the above embodiment, an example was described in which the motors 34A to 34C are provided as functional parts, but the invention is not limited to this aspect. For example, the functional parts may be a heater that heats the seating surface 9 or the support surface 10, or It may also be a fan or the like that blows air.

In the second embodiment, both the main side cover 102 and the auxiliary side cover 103 are provided on the left side of the vehicle seat 101, but the present invention is not limited to this embodiment. The main side cover 102 and the auxiliary side cover 103 may each be provided on the right side of the vehicle seat. Further, the vehicle seat may be provided with only the auxiliary side cover 103, with the main side cover 102 being provided on one side of the vehicle seat, and the auxiliary side cover 103 being provided on the other side of the vehicle seat. may be provided.

In the second embodiment, the second surface 140 is configured to have a larger curvature than the curvature of the extending lower end surface 134 when viewed from the side, but the present invention is not limited to this aspect. For example, as shown in FIG. 9(A), the second surface 160 may be configured to have a linear shape when viewed from the side (first modification). Further, as shown in FIG. 9B, the curvature of the second surface 162 and the curvature of the lower edge of the extended lower end surface 134 may be configured to be equal to each other when viewed from the side (second modification). example).

However, by forming the second surface 140 to have an arc shape when viewed from the side, compared to the case where the second surface 160 is formed to have a linear shape from the side view (for example, see FIG. 9(A)). Thus, the gap between the lower surface of the extending portion 130 and the second surface 140 can be reduced. This makes it difficult for foreign objects to be inserted between the extending portion 130 and the stepped portion 132. Furthermore, as can be understood by comparing the two-dot chain lines in FIGS. 8(A) and 9(B), in the second embodiment, the radius of curvature of the second surface 140 is the lower edge of the extending portion 130 when viewed from the side. Since the radius of curvature of the second surface 140 and the radius of curvature of the lower edge 130A of the extension part 130 are equal to each other, when the seat back 6 is tilted back and forth, the assist The front or rear edge of the side cover 103, more specifically, the front or rear surface of the peripheral edge portion 105 and the front and rear edges of the second surface 140 are less likely to come into contact with each other. Therefore, the rotation range of the seat back 6 can be increased.
