Description
Technical Field
The present invention relates to a vehicle seat device that moves a seat body from a seating position in a forward direction of a vehicle to a lateral position facing a side of a door opening.
Background
A vehicle seat device associated therewith is described in japanese patent laid-open nos. 2013-18341. The vehicle seat device 100 in japanese patent laid-open No. 2013-18341 is a seat device used for a passenger seat of a vehicle. As shown in fig. 8 and 9, in the vehicle seat device 100, in a state where the seat body 102 is located at the origin position (rotation start position), a rotation mechanism (not shown) is operated to horizontally rotate the seat body 102 by α ° about the rotation center C. Here, the origin position of the seat body 102 is set to a position at which the leg of the seated person does not interfere with the pillar P on the front side of the door opening D when the seat body 102 is rotated horizontally.
When the seat body 102 is horizontally rotated by α ° to pass the feet of the seated person through the support column P (see fig. 9), the seat body 102 is horizontally rotated and slid forward (hereinafter, referred to as forward sliding) by operating a forward/backward sliding mechanism (not shown). In this way, the seat main body 102 slides forward while performing horizontal rotation, and when the seat main body 102 is horizontally rotated by β ° to a lateral position toward the door opening side as shown in fig. 10, the swivel mechanism and the forward-backward sliding mechanism are stopped, and the seat main body 102 is held at the lateral position.
Disclosure of Invention
In the vehicle seat device 100, the front-rear slide mechanism operates to slide the seat main body 102 forward while the seat main body 102 is rotated from the angle α ° to the angle β °. Here, the rotation speed of the rotation mechanism and the sliding speed of the front-rear sliding mechanism are set in advance in accordance with the specification of the motor and the like. Therefore, the forward sliding amount L, which is the amount of sliding of the seat body 102 toward the front, is a value obtained by multiplying the sliding speed v by the time t during which the seat body 102 rotates from the angle α ° to the angle β ° (L ═ vt). Further, the origin position (rotation start position) of the seat main body 102 is set based on the forward slide amount L of the front-rear slide mechanism. Here, if the forward sliding amount L can be increased, the origin position can be set further rearward, so that the space under the feet of the seated person is left to be sufficient when the seat main body 102 is horizontally rotated. Therefore, it is also considered to increase the sliding speed of the front-rear sliding mechanism. However, in this case, it is necessary to improve the performance of the motor and the like of the front-rear sliding mechanism, which is not economically preferable.
The invention provides a vehicle seat device which can arrange the original position (rotation starting position) of a seat body at a position closer to the rear under the condition of not changing the sliding speed of a front-back sliding mechanism, thereby enabling a seated person to have a margin in the foot space when the seat body rotates horizontally.
A vehicle seat device according to an aspect of the present invention includes: a seat main body; a rotation mechanism that horizontally rotates the seat main body; a front-rear sliding mechanism that slides the seat main body forward and backward; and a control section. The control unit is configured to move the seat main body from a seating position in a forward direction of the vehicle to a lateral position facing a door opening portion side, and to move the seat main body to a front side of the vehicle in a state where the seat main body is moved to the lateral position.
In the vehicle seat device of the above aspect, the seat body is moved toward the vehicle front side in a state where the seat body is moved to a lateral position toward the door opening portion side. That is, after the horizontal rotation of the seat main body by the rotation mechanism is completed, the seat main body can be slid forward by the forward-backward sliding mechanism. In this way, since the actions of the rotating mechanism and the forward-backward sliding mechanism are not linked, the forward sliding time can be freely set. Therefore, according to the vehicle seat device of the above aspect, the rotation start position (origin position) of the seat main body can be set further rearward, and the space under the feet of the passenger can be made more allowance when the seat main body is rotated.
In the above aspect, the control unit may be configured to slide the seat main body forward while rotating the seat main body horizontally, and move the seat main body from a seating position in the forward direction of the vehicle to a lateral position facing the door opening side.
In the vehicle seat device of the above aspect, the control unit is provided that is configured to move the seat body forward of the vehicle in a state in which the seat body is moved to a lateral position toward the door opening portion side by the operations of the rotation mechanism and the forward-backward sliding mechanism. Therefore, even after the forward sliding operation (hereinafter referred to as "rotating and forward sliding") performed while the seat body is horizontally rotated by the rotating mechanism and the forward and backward sliding mechanism is completed, the seat body can be slid forward. In this way, the forward sliding amount of the seat main body can be increased by the amount of forward sliding performed after the forward sliding is finished by the rotation. As a result, according to the vehicle seat device of the above aspect, the rotation start position (origin position) of the seat main body can be set further rearward, and the space under the feet of the seated person can be made more allowance when the seat main body is rotated. Further, since the seat main body moves forward in the vehicle after moving to the lateral position, a person who assists the passenger in getting on and off can assist from the seat side. In addition, it is possible to ensure the assistance of getting on and off the person.
In the above aspect, the control unit may be configured to drive the motor of the front-rear sliding mechanism for a fixed time period in a state where the seat main body is moved to the lateral position and the motor of the rotating mechanism is stopped. According to the vehicle seat device of the above aspect, a new mechanism for increasing the forward sliding of the seat main body is not required.
In the above aspect, the control unit may be configured to slide the seat body to a predetermined position before horizontally rotating the seat body. According to the vehicle seat device of the above aspect, the rotation mechanism and the slide mechanism can be controlled in a single mode, and the control unit can be configured at a low cost.
In the above aspect, the predetermined position may be a rearward limit position of the seat body. The rearward limit position is a rearmost end of a range in which the seat main body can slide forward and backward. According to the vehicle seat device of the above aspect, when the seat main body is rotated, the space under the feet of the seated person can be more surely made to be sufficient.
According to the present invention, the origin position (rotation start position) of the seat main body can be arranged further rearward without changing the sliding speed of the front-rear sliding mechanism. This allows a seated person to have a margin in the underfoot space when the seat body is rotated horizontally.

Detailed Description
Hereinafter, a vehicle seat device according to an embodiment of the present invention will be described with reference to fig. 1 to 7. As shown in fig. 1 and the like, a vehicle seat device 20 according to the present embodiment is a seat device disposed inside a sliding door opening 12 (hereinafter, referred to as a door opening 12) of a passenger vehicle 10. Here, the front, rear, left, right, and up and down shown in the drawings correspond to the front, rear, left, right, and up and down of the passenger car 10 provided with the vehicle seat device 20. Note that the front, rear, left, and right of the seat in the drawings correspond to the front, rear, and left, and right of the seat body 22 of the vehicle seat device 20.
As shown in fig. 1, 2, and the like, the vehicle seat device 20 includes a seat body 22 and a seat moving device 200 that moves the seat body 22 between a seating position in a vehicle compartment and a lateral position facing the door opening 12 side. The seat main body 22 includes a seat cushion 24 and a seat back 26, and a reclining regulator 28 that regulates a reclining angle (backrest reclining angle) of the seat back 26 is provided at a coupling position of the seat cushion 24 and the seat back 26. As shown in fig. 2, the seat moving device 200 includes: a front-rear slide mechanism 30 provided on a vehicle floor F, and a rotation mechanism 40 provided on a front-rear slide base 31 of the front-rear slide mechanism 30. Further, the seat main body 22 is supported from below by the rotating mechanism 40.
The forward-backward slide mechanism 30 is a mechanism that moves the seat main body 22 in the vehicle longitudinal direction in the vehicle compartment. As shown in fig. 2, the front-rear slide mechanism 30 includes: a pair of left and right fixed side members 32 extending in the front-rear direction of the vehicle on a fixed base portion 33 of the vehicle floor F, and left and right sliders 32s sliding along the pair of left and right fixed side members 32. Further, the left and right sliders 32s are fixed to the lower surface of the front and rear slider base 31. Further, between the fixed base 33 and the front-rear slide base 31, a drive mechanism (not shown) for sliding the front-rear slide base 31 forward and backward with respect to the fixed base 33 and a motor M2 as a drive source are provided.
The rotation mechanism 40 is a mechanism that horizontally rotates the seat main body 22 by about 90 ° between a seating position in the vehicle forward direction and a lateral position facing the door opening 12 side. As shown in fig. 2, the rotation mechanism 40 includes: an inner ring 41 fixed to the front-rear slide base 31, an outer ring 43 rotatably supported on the inner ring 41, and a rotary table 45 fixed to the outer ring 43. The seat main body 22 is mounted on the swivel 45. The front and rear slide base 31 is provided with a drive mechanism (not shown) for rotating the outer ring 43 relative to the inner ring 41, and a motor M1 as a drive source.
The vehicle seat device 20 is provided with a seat ECU50 as a control device that drives the motor M1 of the rotating mechanism 40 and the motor M2 of the front-rear sliding mechanism 30 at predetermined timings (see fig. 3). The seat ECU50 is provided, for example, on the lower side of the seat cushion 24 of the seat main body 22.
Next, the operation of the vehicle seat device 20 will be described based on the timing chart of fig. 3 and fig. 4 to 7. First, as shown in fig. 4, when a get-off switch (not shown) of the seat main body 22 at the seating position is operated in a state where the slide door 13 is slid in the opening direction and the door opening 12 is opened, the motor M2 of the front-rear slide mechanism 30 is operated to retreat the seat main body 22 to the retreat limit position (origin position) and is stopped at the position. The rearward limit position is a rearmost end of the seat main body 22 that can slide forward and rearward. This state is at time i of the timing diagram of fig. 3. Next, the motor M1 of the rotating mechanism 40 is operated to horizontally rotate the seat main body 22 leftward about the rotation center C as shown in fig. 5.
Here, the origin position of the seat main body 22 is set to the rear side so that a sufficient margin is provided between the leg of the passenger and the center pillar 15 on the front side of the door opening 12 when the seat main body 22 is horizontally rotated about the rotation center C. As shown in fig. 5, when the seat main body 22 is rotated horizontally by an angle α ° from the seating position toward the vehicle front side and the legs of the seated person pass through the center pillar 15 (time ii in fig. 3), the motor M2 of the front-rear slide mechanism 30 is operated to move the seat main body 22 forward from the origin position. Thereby, the seat main body 22 horizontally rotates leftward while performing forward sliding.
As shown in fig. 6, in a state where the seat main body 22 is slid forward by a dimension L1 and the seat main body 22 is rotated horizontally by about 90 ° to reach a lateral position toward the door opening 12 side, the motor M1 of the rotating mechanism 40 is stopped (time iii in fig. 3, see fig. 2). In this state, since the motor M2 of the front-rear slide mechanism 30 is operated, the seat main body 22 moves forward in the lateral direction as shown in fig. 7. Further, in a state where the seat main body 22 is moved by the dimension L2 toward the vehicle front side in the lateral direction, the motor M2 of the front-rear slide mechanism 30 is stopped. In this state, when a boarding switch (not shown) of the seat main body 22 is operated, the seat main body 22 returns to the seating position in the forward direction of the vehicle by an operation opposite to the above-described operation.
According to the vehicle seat device 20 of the present embodiment, the seat ECU50 is provided, and is configured to move the seat main body 22 toward the vehicle front side in a state where the seat main body 22 is moved to the lateral position toward the door opening portion 12 side. That is, even after the forward sliding operation by the rotation of the seat main body 22 by the rotation mechanism 40 and the forward/backward sliding mechanism 30 is completed, the seat main body 22 can be slid forward. This can further increase the amount of forward sliding of the seat main body 22. As a result, the rotation start position (origin position) of the seat main body 22 can be set further rearward, and the space under the feet of the seated person can be made more allowance when the seat main body 22 rotates.
When the getting-off switch is operated, the seat body 22 is horizontally rotated after the seat body 22 is retracted to the retracted limit position. Therefore, even if the seat main body 22 is positioned close to the center pillar 15 when the alighting switch is operated, the seat main body 22 can be horizontally rotated from a position where a sufficient margin is generated between the leg of the seated person and the center pillar 15 during the horizontal rotation. Further, since the seat main body 22 inevitably performs the operations of fig. 5 to 7 from the predetermined position (the rearward limit position in the present embodiment), the control of the motor M1 and the motor M2 can be performed in the single mode regardless of where the seat main body 22 is located when the get-off switch is operated, and the operations of the motor M1 and the motor M2 do not need to be changed so as to match the initial position of the seat main body 22, and the seat ECU50 can be configured at a low cost.
Further, since the forward slide can be increased by the forward-backward slide mechanism 30 and the seat ECU50, a new mechanism is not required. Further, since the seat main body 22 moves forward in the vehicle after moving to the lateral position, a person who assists the passenger in getting on and off can assist from the seat side. In addition, it is possible to ensure the assistance of getting on and off the person.
The present invention is not limited to the above embodiments, and can be modified within a range not departing from the gist of the present invention. For example, in the present embodiment, it is exemplified that the seat main body 22 is moved in the lateral direction toward the front of the vehicle by stopping the motor M2 of the front-rear slide mechanism 30 after a predetermined time from the stop of the motor M1 of the rotation mechanism 40. However, a moving mechanism different from the front-rear slide mechanism 30 may be provided so that the seat main body 22 moves toward the vehicle front side in the lateral direction. Although the rotation mechanism 40 and the front-rear slide mechanism 30 are operated in association with each other in the present embodiment, the front-rear slide mechanism 30 may be operated after the rotation mechanism 40 is operated. In the present embodiment, the present invention is applied to a seat disposed inside the sliding door opening 12 as an example, but the present invention may be applied to a passenger seat or the like, for example.
