Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a power seat for an automobile that saves labor in assembling the seat into a vehicle body.

(Prior Art) Conventionally, a power seat for an automobile is known that includes a slider attached to the seat bottom, a slider motor and a reclining motor for operating these, operation switches for driving these motors, and a connection terminal for a battery, etc. When this conventional power seat is assembled to the vehicle body, the seat 1 is aligned with the seat bottom 11 relative to the slider 13 as shown in FIG.
is set to the most forward position and the seat back 12 is set to a position tilted forward, whereby of the mounting holes 14a, 14b formed at the front and rear ends of the lower rail 131 of the slider 13, the mounting hole 14a at the rear end is left exposed.

To attach seat 1 in this state to vehicle body B,
First, the bolts 15 are inserted into the mounting holes 14a at the rear end of the lower rail 131 and fixed. Next, the connecting terminal (not shown) is connected to a battery, and the seat 1 is moved backward by operating the operating switch 2, thereby exposing the mounting hole 14b at the front end of the lower rail 131. The seat 1 is attached to the vehicle body B by fixing the front end of the lower rail 131 to the vehicle body B through the exposed attachment hole 14b.

Therefore, in the production line of automobiles having the above-mentioned power seats, it is necessary to assemble the battery before the seat, and this imposes restrictions on the configuration of the above-mentioned production line. Furthermore, when assembling the seat, it is necessary to connect the battery and switch the operating switch in order to operate the seat in reverse, which requires time and effort. Further, after the seat is attached to the vehicle body, it is necessary to rotate the seat bag rearward to the normal upright position by operating an operating switch.

For this reason, a working power source is provided separately from the battery.
It is conceivable to operate the seat using this working power source, but if the battery is already connected in this case, there is a risk of it being shot within the circuit.

(Purpose of the invention) This invention was made in order to solve such conventional problems, and it is possible to easily and reliably attach the battery to the vehicle body regardless of the direction in which the battery is assembled. The present invention provides a power seat for an automobile that can save labor.

(Structure of the invention) This invention has an operation switch and a drive motor, and the drive motor is configured in a circuit such that it is connected to a battery via the operation switch, and the drive motor is configured to be connected to a battery through the operation switch. In an automobile power seat configured to drive the seat, the operating switch is electrically disconnected at its off operating position, and a pair of lead wires each having a connecting end connected to the circuit,
The driving motor is directly driven by connecting a working power source other than the battery to this lead wire while the operation switch is in the off position.

According to the above configuration, the drive motor can be driven to operate the seat by connecting the working power source to the lead-out line, so that the seat can be moved backward after the rear end of the lower rail for the seat slider is fixed. This can be done independently of battery power, and the switching operation using an operating switch, which is conventionally required, can be omitted. Further, when the seat is operated by the working power source, the working power source and the battery are cut off by the operation switch, so that they will not be fired.

(Example) In FIG. 2, the front seats 1a and 1b have a slider 13 on the lower surface of the seat bottom 11.
are attached to the mounting holes 14a, 1 formed at the front and rear ends of the lower rail 131 of this slider 13.
The front seats 1a, 1b are attached to the vehicle body B by bolts 15 passing through the front seats 4b.
Further, the two front seats 1a and 1b have a first operating switch group 2 on opposite sides of the seat bottom 11, that is, a side facing a front door (not shown), and a first operation switch group 2 on opposite sides of the seat back 12, that is, the side facing the front door (not shown). A second operation switch group 3 is attached to the upper part of the side surface on the center side.

The first and second operation switch groups 2 and 3
have slider switches 21, 31, reclining switches 22, 32, etc., and these switches 21, 31, 22, 32 are not shown so that the forward/reverse rotation direction of the motor can be switched by switching the switches 21, 31, 22, 32, etc. Connected to the slider motor or reclining motor. Therefore, the front seats 1a, 1b are moved forward/reverse or tilted forward/backward by operating the switch groups 2, 3.

FIG. 1 shows the circuit configuration of the first slider switch 21, second slider switch 31, slider motor 5, etc. The first slider switch 21 is a pair of changeover switches 21
The pair of changeover switches 21a and 21b are configured to be switched to three switching positions in conjunction with each other by the switching operation of the first slider switch 21. The second slider switch 31 also has a pair of changeover switches 31.
The pair of changeover switches 31a and 31b are configured to be switched to three switching positions in conjunction with each other by the switching operation of the second slider switch 31.

By switching the first slider switch 21 to the forward operation side, the pair of changeover switches 21
a and 21b are adapted to be switched in conjunction with each other from a neutral position (OFF operation position) shown by a solid line in FIG. 1 to a normal rotation operation position on the side of contacts 40 and 41. As a result, one changeover switch 21a (on the right side in FIG. 1) is connected to the contact 40 on the battery 6 side, and the other changeover switch 21a (on the left side in FIG. 1) is connected to the contact 40 on the battery 6 side.
b is connected to the contact 41 on the ground 7 side.

Further, by switching the first slider switch 21 to the reverse operation side, the pair of changeover switches 21a and 21b move from the neutral position to the contact 4.
The reverse operation positions on the 2 and 43 sides are switched in conjunction with each other. As a result, one changeover switch 21a is connected to the contact 42 on the ground 7 side, and the other changeover switch 21b is connected to the contact 43 on the battery 6 side.

One of the changeover switches 31a, whose fixed contact 311a is connected to the motor 5, is connected to the neutral contact 44 in its OFF operating position;
is connected to the fixed contact 211a of one of the changeover switches 21a of the first slider switch 21. Also, the other changeover switch 31b whose fixed contact 311b is connected to the motor 5 also
In the OFF operating position, it is connected to a neutral contact 45, and this neutral contact 45 is connected to the fixed contact 211b of the other changeover switch 21b of the first slider switch 21. Thereby, when the second slider switch 31 is in the OFF state, the motor 5 is driven by the switching operation of the first slider switch 21.

By switching the second slider switch 31 to the forward operation side, the pair of changeover switches 31
a and 31b are adapted to be switched in conjunction with each other from a neutral position (OFF state) shown by a solid line in FIG. 1 to a normal rotation operating position on the side of contacts 46 and 47.
As a result, the selector switch 31a on one side (on the right side in FIG. 1) is connected to the contact 46 on the battery 6 side.
The other switch 31b (on the left side in FIG. 1) is connected to the contact 47 on the ground 7 side.

Further, by switching the second slider switch 31 to the reverse operation side, the pair of changeover switches 31a and 31b move from the neutral position to the contact point 4.
The reverse operation positions on the 8 and 49 sides are switched in conjunction with each other. As a result, one changeover switch 31a is connected to the contact 48 on the ground 7 side, and the other changeover switch 31b is connected to the contact 49 on the battery 6 side. Note that the battery 6 and the ground 7 are connected to each other by a connector 61 and a connector 71, respectively.

In addition, each fixed contact 211 of the pair of changeover switches 21a and 21b of the first slider switch 21
A, 211b and the lines 81, 82 connecting the neutral contacts 44, 45 of the pair of changeover switches 31a, 31b of the second slider switch 31 are connected to one ends of the linework power supply lead lines 91, 92, At the other ends of the lead wires 91 and 92, connectors (connection ends) 911 and 921 that connect to the line work power source (work power source) 10 are provided.

Note that the first and second reclining switches 22 and 32 and the reclining motor are the same as those of the first and second slider switches 21 and 31.
It is constructed of a circuit (not shown) similar to that of the above circuit, and this circuit is also provided with a line work power source lead wire.

In the assembly work line for attaching the power seat having the above configuration to the vehicle body, the seats 1a and 1b are set at the most forward position with respect to the lower rail 131 of the slider 13, as shown in FIG. Rear end mounting hole 1
4a is left exposed. Further, the seat back 12 is set in a forward tilted position, so that the seats 1a and 1b can be easily inserted into the vehicle interior through the door attachment opening.

To attach the seats 1a and 1b to the vehicle body B, first fix the rear end of the lower rail 131 to the vehicle body B with bolts and nuts 15, and then connect the lines to the connectors 911 and 921 of the linework power supply lead lines 91 and 92. The work power source 10 may be connected.

At this time, the first and second slider switches 2
1 and 31 are set to the OFF operating position, and therefore the motor 5 and battery 6 are cut off. Therefore, even if the battery 6 and the ground 7 are connected to the connectors 61 and 71 when the line work power supply 10 is connected, there is no chance of a short circuit within the circuit.

As shown in FIG. 3, the current flows from the line work power supply 10 to the motor 5 via the connector 921, the lead wire 92, the line 82, the neutral contact 45, and the changeover switch 31b, and from the motor 5 to the changeover switch 31a and the neutral contact. 44, line 81, lead wire 91, and connector 911 to line work power supply 10. Then, the motor 5 is driven in the reverse direction, and the seats 1a and 1b are driven backward only during the time that the line work power source 10 is connected to the connectors 911 and 921. As a result, the mounting hole 14 at the front end of the lower rail 131
b can be exposed, and this mounting hole 14b
The front end of the lower rail 131 of the slider 13 can be fixed via.

Therefore, the power seats 1a, 1b can be attached to the vehicle body B regardless of whether or not the battery 6 is assembled to the vehicle body B, and the installation work is performed in a manner that is conventionally required for backward movement of the seat. It is possible to omit the switching operation by the operation switch 21 which is performed after the connection work with the battery 6 and the ground 7 via the connectors 61 and 71.
As a result, the number of man-hours required for assembling the sheets on the production line can be reduced, and labor savings can be achieved.

Note that the rotation operation of the seat back 12 to the normal upright state is performed separately from the above-mentioned reverse operation using the linework power supply lead wire provided in the circuit for driving the reclining motor by the reclining switches 22 and 32. However, for example, it is possible to integrate the connectors of both line work power supply lead wires with a 4-wire connector so that reverse movement and backward tilting can be operated at the same time by one connection operation with the line work power supply 10. You can also do this.

Next, the second part of the power seat in this example is
The operation of the two operation switch groups 2 and 3 will be explained. The first operation switch group 2 and the second operation switch group 3 are normally set to the OFF state, and the changeover switches 21a, 21b, 31a, and 31b are in their respective neutral positions as shown by solid lines in FIG. . From this state, for example, in order for a person sitting in the front seat 1b to move the seat forward, he or she only has to operate the first slider switch 21 to move the seat forward.

When the above switching operation is performed, the pair of changeover switches 21a and 21b are connected to the contacts 40 and 41 as shown by solid lines in FIG. 4, and current flows from the battery 6 to the contacts as shown by solid lines in FIG. 40,
Changeover switch 21a and changeover switch 3
1a to the motor 5, and from the motor 5 to the changeover switch 31b and the changeover switch 21b.
and flows to ground 7 via contact 41. As a result, the motor 5 is driven to rotate in the forward direction shown by the solid arrow in the figure, and the front seat 1b is moved forward.

Conversely, to move the front seat 1b backwards,
It is sufficient to switch the first slider switch 21 to the reverse operation side. Then, the pair of changeover switches 21a and 21b are connected to the contacts 42 and 43, and current flows to the motor 5 in the opposite direction to the forward operation as shown by the broken line arrow in FIG. As a result, the motor 5 is rotated in the reverse direction indicated by the broken line arrow, and the front seat 1b is moved backward.

In order for the occupant of the rear seat 1c (see FIG. 2) to move the front seat 1b forward, regardless of the operating position of the first slider switch 21,
It is sufficient to switch the second slider switch 31 to the forward operation side.

When the above switching operation is performed, the pair of changeover switches 31a and 31b are connected to the contacts 46 and 47 as shown by solid lines in FIG. 46 and the changeover switch 31a to the motor 5, and from the motor 5 to the ground 7 through the changeover switch 31b and the contact 47. As a result, the motor 5 is driven to rotate in the forward direction shown by the solid arrow in the figure, and the front seat 1b is moved forward.

Conversely, to move the front seat 1b backwards,
It is sufficient to switch the second slider switch 31 to the reverse operation side. Then, the pair of changeover switches 31a and 31b are connected to the contacts 48 and 49, and current flows to the motor 5 in the opposite direction to the forward operation as shown by the broken line arrow in FIG. As a result, the motor 5 is driven to rotate in the reverse direction indicated by the dashed arrow, and the front seat 1b is moved backward.

When this second slider switch 31 is operated to switch to the forward operation side or the reverse operation side, the pair of changeover switches 31a, 31 that were previously connected
b and the neutral contacts 44, 45 are separated from each other. This causes the first slider switch 21 to
The connection line to the motor 5 via the neutral contact 4
It is cut off at the 4,45 position. Therefore, for example, even if the first slider switch 21 is switched to the forward operating side of the contacts 40, 41, the motor 5 is not operated, and the motor 5 is switched to the forward operating side of the contacts 40, 41.
It will be activated only by the switching operation.

That is, the motor 5 is driven in the forward and reverse directions by the switching operation of the second slider switch 31 in priority to the switching operation of the first slider switch 21. Therefore, even if different switching operations are performed at the same time on the first slider switch 21 and the second slider switch 31, the sheets 1a and 1 can be reliably switched without causing any firing within the circuit.
b can be activated.

In this way, the second slider switch 31, which has priority over the first slider switch 21, is attached to the upper side of the seat back 12, so that the person sitting in the rear seat 1c can move the front seat in the normal sitting position by simply extending his arm. The front and rear positions of the seats 1a and 1b can be easily and reliably changed. In addition, a first slider switch 31 having the second slider switch 31 is
The circuit shown in the figure has a circuit between the first slider switch 21 and the motor 5 without changing the circuit of the conventional power seat, in which the circuit is composed of the first slider switch 21 and the motor 5. It can be formed by simply adding two slider switches 31.

The above is the first and second slider switch 2.
1 and 31 have been described, the first and second reclining switches 22 and 32 can also provide the same effect as the slider switches 21 and 31, so that the person sitting in the rear seat 1c can move the front seat in the normal sitting position. Seat back 12
You can easily change the forward/backward tilt position of the

The configuration of the first and second operation switch groups 2 and 3 in the above embodiment is designed with emphasis on the comfort and operability of the occupants in the rear seat 1c. When placing emphasis on comfort and operability for the seated person, for example, the first and second seats in FIG.
Reverse the arrangement of slider switches 21 and 31,
By doing so, the switching operation of the first slider switch 21 may be given priority over the switching operation of the second slider switch 31.

Note that in the above embodiment, the second switch group 3
Although it is attached to the upper side surface of the seat bag 12, the present invention is not limited to this, and it may be attached to the back surface of the seat bag 12, for example. Further, the second switch group 3 may be attached to the rear door or configured to be remote controlled.

(Effects of the invention) According to the automobile power seat of this invention, by connecting a working power source to the lead wire, the drive motor can be directly driven to operate the seat, so it is easy to attach the power seat to the car body. of,
This can be done regardless of whether or not the battery is assembled to the vehicle body. Regarding the installation work,
It is possible to omit the switching operation using an operating switch, which was conventionally required for the backward movement of the seat. Furthermore, since the working power source and battery are shut off by an operating switch, there is no risk of a shock. This makes it possible to easily and reliably assemble the sheets on the production line, and to reduce the number of man-hours involved.
It is possible to save labor.
