  2. Description of the Related Art Conventionally, there is known a seat position control device that stores a seat position set by a driver and can return a seat body to a preset driving position even when another person changes the seat position.

  Patent Document 1 discloses a technique for adjusting the seat position according to the operation position information stored in the ignition key by inserting the ignition key. Patent Document 2 discloses a technique for adjusting a seat position in accordance with driving position information stored in advance in a key when an ignition key is inserted and an ON operation is detected.

Japanese Patent No. 3147658 JP-A-9-123924

  In the above-described conventional device, the seat position moves backward more greatly than the normal driving position when getting on and off so that the driver can easily get on and off. For this reason, at the time of inserting the ignition key, the key operation is complicated because the distance from the driver to the key cylinder is long and the body needs to be tilted largely forward.

  Accordingly, it is an object of the present invention to provide a seat position control device that can easily get on and off and can easily adjust the seat position when getting on.

  In order to achieve the above object, a first characteristic configuration of a seat position control device according to the present invention is characterized in that at least one seat position of the seat body is stored in a position adjusting means for adjusting the position of the seat body in the front-rear direction in the vehicle. In the seat position control device provided with a storage means for controlling and a control means for controlling the seat position, the seat belt wearing recognition means for receiving a signal indicating that the seat belt is worn is provided. When the seat belt is detected by the means, the position adjusting means adjusts the seat position of the seat body to the initial position stored in the storage means.

When boarding to drive a vehicle, the seat position is usually adjusted immediately after boarding. Also, a seated driver usually wears a seat belt early. These operations are usually performed before the engine is started. Generally, a seat belt buckle is provided with a means for recognizing whether or not it is attached. In this configuration, for example, this means is used to move the seat body to the initial position when the seat belt is attached. Accordingly, the seat position control device can be obtained while using the conventional vehicle equipment as it is.
The initial position of the present invention is preferably a position where a driver with an average physique can easily perform an engine starting operation. Therefore, for example, it is preferable to set the position approximately at the center of the slide range of the seat body.

  A second characteristic configuration of the seat position control device according to the present invention includes door opening / closing recognition means for receiving a signal indicating that opening / closing of the door of the vehicle is detected, and in addition to mounting the seat belt, the door When the closed state of the door by the opening / closing recognition means is detected, the initial position is adjusted.

  In this configuration, detection of the closed state of the door, in addition to detection of seat belt attachment, serves as a trigger for performing the seat position adjustment operation. The fact that the vehicle door is closed means that the driver's intention to drive is more reliable. If the door is left open, there is a possibility that the driver will get off again without starting the engine. If the seat body is moved to the driving position in such a situation, the driver's dismounting operation is hindered. Therefore, if the seat body is moved by detecting the closed state of the door as in this configuration, a more reasonable seat position control device for the driver can be obtained.

  A third characteristic configuration of the seat position control device according to the present invention includes a portable device and a recognition unit that recognizes the presence of the portable device when the position adjusting device is within a predetermined range from the vehicle. When the recognition means recognizes that the machine is within the predetermined range, it is added as a condition for adjusting the seat body to the initial position.

As in this configuration, by adding the condition that the portable device is within the predetermined range to the first feature configuration or the second feature configuration, an excellent seat position control device can be obtained even in terms of security.
For example, the predetermined range is usually a range shorter than a distance at which a signal transmitted from the portable device can be recognized by the recognition means.

In this configuration, in many cases, the driver holding the portable device recognizes the portable device while the driver is seated on the seat body.
In other words, as in this configuration, by adding the condition that the portable device is within a predetermined range as the condition for moving to the initial position, the seat position can be adjusted substantially only to the driver, which is excellent in terms of security. A sheet position control device can be obtained.

  A fourth characteristic configuration of the seat position control device according to the present invention is that the seat body is adjusted to a getting-on / off position behind the initial position before the driver gets on or when getting off.

As described above, the initial position is preferably set assuming a driver with an average physique. However, this initial position is a standard position where it is easy to start the engine, and the steering wheel is easy to operate. Therefore, when getting on and off, the steering wheel may interfere with the driver.
Therefore, as in this configuration, when the passenger gets on and off, the seat body is retracted backward from the initial position, so that a seat position control device having ease of getting on and off can be obtained.

  A fifth characteristic configuration of the seat position control device according to the present invention is that the initial position is an operation position that is a position of the seat body when the driver operates.

Usually, the driving position is set to a position where the driver can drive most easily. Therefore, the steering wheel operation and the ignition key operation can be easily performed in a normal posture.
If it is this structure, it can transfer to driving | operation operation, without moving a sheet | seat main body immediately after performing engine starting operation.

In the seat position control device of the present invention, the position adjusting means constituting the device stores the initial position of the seat body provided in the vehicle, and this position adjusting means allows the seat belt to be worn when the driver gets on and off. When detected, the sheet body is moved to the initial position. By doing so, an attempt is made to obtain a seat position control device Y that is easy to perform operations such as engine start (see FIGS. 1 and 2).
Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the vehicle seat device X includes a seat back 11 and a headrest 12 that are configured so that the angle of reclining can be adjusted, and is electrically driven to slide the seat body 1 in the longitudinal direction of the vehicle. The slide mechanism 2 is provided.
The slide mechanism 2 includes a position adjusting unit 3 that adjusts the position of the seat body 1 in the front-rear direction of the vehicle, a pair of lower rails 22 that are fixed to the vehicle floor, and the front-rear direction of the vehicle along the lower rails 22. And a pair of movable upper rails 23.
The position adjusting means 3 includes a storage means 24 for storing at least one position of the seat body 1, a motor for adjusting the position of the seat body 1 in the front-rear direction, a control means 25 for the motor, and the like.

  In the apparatus of the present invention, with respect to the position of the seat body 1, the position set when the driver drives is referred to as the driving position, and the position for starting the engine immediately after the driver gets on the vehicle is the initial position. This is called a position. The driving position is individually set by each driver according to his / her physique. On the other hand, the initial position (FIG. 1 (b)) is set to one preset position in the present embodiment. The initial position is a position where the engine starting operation or the like can be performed without any particular discomfort. Therefore, it is not always necessary to accurately match the physique of each driver.

In the apparatus of the present invention, the seat body 1 is moved to the initial position when the seat belt 5 is detected. Many ordinary vehicles are provided with a switch on the buckle of the seat belt in order to recognize whether or not the seat belt 5 is attached and issue a warning. In the present invention, the seat belt wearing recognition means 51 receives a signal from the switch as a signal indicating that the seat belt is worn.
When the driver gets on the vehicle, the seat belt 5 is usually worn early. Therefore, if the seat body 1 is moved when the seat belt 5 is mounted as in the present invention, an appropriate seat position can be secured prior to the subsequent engine starting operation, and the starting operation is facilitated.

The specific position of the initial position is set to the center position of the slide adjustable range of the seat body 1, for example. If it is this position, if it is a driver of an average physique, engine starting operation can be performed without a sense of incongruity. Of course, the position of the initial position may be set arbitrarily.
The movement to the initial position is performed when the driver moves the seat body 1 that has been set to the driving position on the front side in the previous driving to the rear initial position and the seat body 1 that has been set on the rear side. Both cases of moving forward are included. Further, when the previous driving position remains the initial position, the seat body 1 does not move when the next seat belt 5 is attached.
Further, as will be described later, when the driver holds a portable device that transmits a specific identification code to the vehicle, an arbitrary seat position corresponding to each driver becomes the driving position, and the driving position in this case is set as the initial position. Also good.

  The initial position is stored in the storage means 24, and the seat body 1 is driven by the position adjusting means 3 when the seat belt attachment recognition means detects the seat belt attachment (FIG. 3: # 11 to # 13). .

In the seat position control device of the present invention, it is preferable that the seat main body 1 is configured to be largely retracted from the initial position when getting on and off in order to make it easier for the driver to get on and off.
Such a backward movement of the seat body 1 is configured to be performed at an arbitrary time, for example, before the driver gets on or when the driver gets off. The timing of retracting the seat body 1 can be set, for example, when the seat belt 5 is removed when getting off, or when the door is opened when getting on.
In particular, if the seat body 1 is moved when getting off, the driver can easily get on and off both when getting off and at the next boarding.
Further, when the vehicle is getting off, it is usually immediately after the engine is stopped, so that the state of charge of the battery is sufficient. The battery in the engine room is warmed to some extent and has a sufficient electromotive force. Therefore, if the seat body 1 is moved when getting off, the burden on the battery can be reduced.

[Another embodiment 1]
In the embodiment described above, the seat main body 1 is moved to the initial position by detecting the seat belt 5 being attached. However, even when the seat belt 5 is worn, if the door is still open, the surrounding luggage may be sorted before the engine is started, or the driver may get off again without starting the engine. In some cases, it is preferable that the sheet body 1 does not move to the initial position.
Therefore, as in this embodiment, it is also preferable to add the following conditions as conditions for moving the sheet body 1.
That is, as shown in FIG. 2, the door opening / closing recognition means 6 for receiving a signal indicating that the opening / closing of the door of the vehicle is detected is provided, and the seat body 1 is initialized when the door closing state is detected. It is configured to adjust to the position (FIG. 2B).
That is, as in this configuration, by using the seat belt 5 attachment and the door closing operation as AND conditions, the driver's intention to start the vehicle is more accurately recognized, and the seat body is inadvertently 1 can be prevented, and a more rational sheet position control device can be obtained (FIG. 4: # 21 to # 24).

[Another embodiment 2]
The present invention further includes a portable device 4 (see FIG. 2B) held by the driver as a part of the position adjusting means 3, and a recognition means 41 provided on the vehicle so that the portable device 4 can be recognized. It can also be prepared. When the portable device 4 is within a predetermined range from the vehicle, the recognition unit 41 recognizes the presence of the portable device 4. That is, a further AND condition is that the portable device 4 is in a predetermined range. The predetermined range is usually a range within a distance where a signal transmitted from the portable device 4 can be recognized by the recognition means 41. For example, the predetermined range is about 1 to 2 m from the portable device 4 to the recognition means 41.

  In this configuration, the state where the recognition unit 41 recognizes the portable device 4 can be determined to be a state where the driver holding the portable device 4 is seated on the seat body 1 in many cases. Therefore, by adding the condition that the portable device 4 is within a predetermined range as the condition for moving to the initial position, the seat position can be adjusted substantially only to the driver (FIG. 5: # 31 to # 35). ). Therefore, the sheet position control device Y excellent in security can be obtained.

  The recognition unit 41 may be configured to be included in the position adjustment unit 3 or may be configured separately from the position adjustment unit 3.

[Another embodiment 3]
As shown in the second embodiment, the portable device 4 is not limited to recognizing only whether it is within a predetermined range from the vehicle, and issues a unique identification code so that the driver can be identified. Also good.

  In this case, the portable device 4 transmits an identification code unique to the recognition unit 41, and the position adjustment unit 3 moves the sheet body 1 to the sheet position set for each identification code. Thereby, even when a plurality of drivers share one vehicle, it is possible to set an initial position or a getting-on / off position according to each owner, and the seat position control device Y is more user-friendly. Can be obtained.

  For example, when the initial position is substantially in the center of the slide range of the seat body 1, it is cramped when a driver with a large physique is seated. However, by transmitting a unique identification code for each portable device 4, the initial position can be set according to the physique of the driver.

  As in the present invention, the apparatus for moving the seat main body to the initial position by attaching the seat belt 5 is not limited to the vehicle, and the position / posture of the seat main body is adjusted according to the physique of the driver, such as an aircraft, a ship, various play facilities, Can be widely applied to what needs to be adjusted.
