2. Description of the Related Art It is known that a driver's seat and a passenger's seat can take both a forward facing state in which the vehicle seat faces the front of the vehicle and a facing state in which the driver's seat and the passenger seat face each other than the front of the vehicle.

As such a rotating device for a front seat for an automobile, for example, as shown in Japanese Utility Model Laid-Open Publication No. 59-99832, an ignition circuit of an engine is provided with a contact which is turned off by energizing an exciting coil of a relay. A switch which is turned off when the transmission is in a neutral state and an O
By connecting FF-operated switches in series,
When the seat is rotating backward and the transmission is in a forward or reverse position other than neutral, the ignition circuit is shut off to prohibit the vehicle from running and avoid running the vehicle with the seat rotated backward. (First conventional example) and JP-A-59-22752.
As shown in Japanese Patent Application Publication No. 8 (1993) -08, the seating state of the passenger side seat is based on the seating state of the driver side seat, and the driver's seat side forward facing state is based on the passenger seat side forward facing state. And a connecting lever for detecting the position of the rotary release lever and an engaging pin for engaging with the rotary release lever are connected by a remote control wire (second conventional example) or disclosed in Japanese Patent Application Laid-Open No. 57-11127. A lock mechanism for locking the movable seat of the vehicle and an actuator for switching the operation of the lock mechanism are provided to detect a running state of the vehicle by a key switch, and the locking mechanism is operated by the actuator in the running state. There has been proposed a third conventional example in which the movable sheet is prevented from rotating or the like, thereby enhancing safety.

[0004]

By the way, when the vehicle is running while the passenger seat is in the opposite state,
Since there is a problem in terms of safety, if the driver's seat is in the forward state and the passenger's seat is in the opposite state based on the above-described first and second conventional examples, the operation of the engine is blocked. It is conceivable to avoid running the automobile.

However, in such a case, even if the air conditioner or the like is operated while the vehicle is stopped, for example,
Since the engine does not operate as long as both seats are in the above-described state, it is not possible to obtain an air-conditioning effect or the like by operating the air conditioner, and there is a problem that convenience is lacking.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to prevent the operation of the engine when the driver's seat is in the forward state and the passenger's seat is in the opposite state as described above. In addition, by allowing the operation of the engine under predetermined conditions, the air conditioning effect of the operation of the air conditioner and the like can be obtained, and it is possible to achieve both safety and convenience in a state in which the passenger seat is opposed to the front seat for an automobile. An object of the present invention is to provide a seat rotating device.

[0007]

Means for Solving the Problems To achieve the above object, a solution of the present invention according to claim 1 is that a driver seat and a passenger seat both face forward in a forward direction of the vehicle body and a confronting seat in which the passenger seat and passenger side face other than the vehicle front. The present invention is directed to a rotating device for a front seat for a vehicle that can assume a state.

Further, there are provided first seat position detecting means for detecting whether or not the driver seat is in the forward state, and second seat position detecting means for detecting whether or not the passenger seat is in the forward state. Further, receiving the output of the first and second seat position detecting means, when the driver seat is in the forward state and the passenger seat is in the seated state, the operation of the engine is prevented, while the driver seat and the passenger are prevented from operating. Control means is provided for permitting operation of the engine when both seats are in the opposite state.

With this configuration, when the driver's seat is in the forward state and the passenger's seat is in the opposite state, the operation of the engine is blocked by the control means, so that traveling of the automobile can be avoided.

On the other hand, when both the driver's seat and the passenger's seat are in the seated state, the engine can be operated, so that the air conditioner or the like can be operated when the vehicle is stopped, thereby improving convenience. can do.

Above the hook members 7, 8, holding members 9, 10 are fixed to prevent the hook members 6 from coming off when the hook members 6, 8 are locked. Has been established.

On the other hand, the passenger seat side is configured similarly to the driver seat side. That is, as shown in FIGS. 3 and 4, an annular guide member 21 is fixedly mounted on the rotary base 1B by a plurality of mounting tools 22, while the rotary base 1B and the guide member are mounted on the lower surface of the rotary table 2B. An engagement member 24 having an engagement portion 24a on the inner peripheral edge that is slidably engaged with the engagement portion formed by the engagement member 24 is fixedly provided.

A locking member 25 whose tip extends downward is fixed to the rotary table 2B.
A hook member (only the front hook member 26 is shown in the drawing) for releasably engaging the hook 5 is rotatably supported on the front and rear sides of the rotary base 1B, and a rotary release lever 26a (rear side) connected to the hook member 26 is provided. By rotating the rotation release lever (shown by 27a), the locking of the locking member 25 by the hook member 26 is released, and the driver's seat can be rotated.

Above the hook member 26, when the hook member 25 is engaged with the hook member 26, the hook member 25
The holding member 28 is fixedly provided to prevent the detachment.

An actuator 31 is mounted on the rotary table 2B, and a swing lever 32 is connected to the tip of an operating rod 31a. In the swing lever 32, when the front passenger seat is in the forward direction, the front end locking portion 32a is located above the hook member 26, and the hook member 26 rotates to move the hook member 26 and the hooking member 25. A rotation preventing position (see the solid line in FIG. 4), which prevents the engagement of the passenger seat from rotating, and a hook member 2;
6 and a rotation permissible position (see a chain line in FIG. 4) in which the front passenger seat can be rotated.
Thus, rotation control means provided on the passenger seat for preventing or releasing the operation of the rotation release lever 26a in conjunction with the operation of the actuator 31 is configured.

The rotary table 2B is provided with a position detecting switch 33 as a second seat position detecting means for detecting whether or not the front passenger seat is in the forward position, and protrudes upward at the front side of the rotary base 1. The protruding member 34 erected on the switch terminal 3 of the position detection switch 33
By touching 3a, the front-facing state of the passenger seat is detected. In addition, since the protruding member is not provided on the rear side of the rotation base 1B, the position detection switch 33 is not turned on when the front passenger seat is in the seated state.

As shown by a chain line in FIGS. 2 and 7,
Position detection switch 15 as first sheet position detection means
Further, an actuator 11 is provided so that not only the above-mentioned passenger seat but also the driver seat are locked non-rotatably in the seated state.

That is, the rotary table 2A is provided with a position detection switch 15 for electrically detecting whether the driver's seat is in the frontward position or in the seating position facing the rear of the vehicle body other than the front of the vehicle body. A protruding member 16 erected so as to protrude upward at the rear side contacts the switch terminal 15a of the position detection switch 15 so that the seating state of the driver's seat can be detected.

Since no protruding member is provided on the front side of the rotary base 1A, the position detection switch 15 is not turned on when the driver's seat faces forward in the vehicle body.

An actuator 11 is mounted on the rotary table 2A, and a swing lever 12 is connected to the tip of an operating rod 11a. When the front end locking portion 12a is located above the hook member 7 and the driver seat is in a seated state in which the driver's seat faces rearward in conjunction with the operation of the actuator 11, the swinging lever 12 rotates. To prevent the driver's seat from rotating, and a rotation allowable position at which the rotation of the hook member 7 is allowed and the driver's seat can be rotated. I take it as an alternative.

As shown in FIG. 5, the position detection switches 15 and 33 are connected in parallel, and are interposed between the starter switch 41 and the exciting coil 43a of the relay switch 43 of the starter motor 42. The relay switch 43 is turned ON only when the driver's seat is in the seated state or when the passenger's seat is in the forward direction, and in other states, the relay switch 43 is OFF, so the starter switch 41 is operated. However, the starter motor 42 does not operate.

Therefore, in this case, as shown in FIG. 6, the operation of the engine is prevented only when the driver's seat 201 is in the forward state and the passenger's seat 202 is in the opposite state (see FIG. 6A). (FIG. 6B)
(D)), the operation of the engine becomes possible. FIG.
, The seat cushion of the driver's seat 201 is 2
01a, the seat back is indicated by 201b, and the seat cushion of the passenger seat 202 is 202a.
, And the seat back is indicated by 202b.

If the driver's seat is facing forward and the front passenger's seat is in the seating position, the engine does not operate. If the driver's seat is brought into the seating state from this state, the engine operates. The air conditioner and the like can be operated in such a state.

When the ignition switch is turned on, the actuators 11 and 31 operate to lock the driver's seat and the passenger's seat so that they cannot be rotated.

Further, the operation of the engine is stopped when the driver's seat is in the forward state and the passenger's seat is in the seated state. In other words, the engine is stopped when both the driver's seat and the passenger's seat are in the seated state. Is activated (see FIG. 6D), the driver's seat is locked in the opposite state. As described above, when the front passenger seat is in the seated state, the driver seat is locked in the seated state, so that the driver's seat is inadvertently turned to the forward state, so that driving is not performed and safety is improved. .

The actuator 11 (same for the actuator 31) is configured as shown in FIG.
That is, when the ignition is turned on, a current flows through the exciting coils 51a and 52a of the relay switches 51 and 52, and the contacts 51b and 52b are switched.
Current flows through the contact seat 53a to lock and unlock the driver's seat depending on the state of the contact 53a.

[0031]

As described above, according to the first aspect of the present invention, when the driver's seat is in the forward state and the passenger's seat is in the seated state, the operation of the engine is prevented, and both seats are seated. By allowing the operation of the engine when it is in the state, even if the passenger seat is in the seated state, if the driver's seat is in the seated state, the air conditioner etc. can be operated by the engine operation. Thus, it is possible to enhance the comfort in the vehicle interior, and to achieve both safety and convenience in the state where the front passenger seat is opposed.
