Best Mode for Carrying Out the Invention Embodiments of the present invention will now be described with reference to the drawings. 1 is an exploded perspective view according to an embodiment, Figure 2 is a plan view of the coupled state, Figure 3 shows a cross-sectional view of the coupled state.

Referring to the drawings, the seat rotating apparatus indicated by the reference numeral 1 as a whole is coupled to the guide rail installed in the flow fan (not shown), the front and rear running base 10 and the front and rear running base 10 to run back and forth It includes a seat rotating plate 20 for supporting the passenger seat 40 rotatably on.

The front and rear running base 10 is formed of a plate body bent downward at both ends in the longitudinal direction, and a circular groove 11 having a predetermined diameter is formed at the center thereof, and a seat is formed on the peripheral flange of the circular groove 11. A ring-shaped set 12 facing the rotatable plate 20 so as to be rotatable is coupled in a state protruding from the upper surface, and the locking groove 13 into which the seat rotation lever to be described later is inserted into the outer periphery of the set 12. ) Is formed.

The seat rotating plate 20 has a circular groove 21 having the same diameter as the circular groove 11 formed in the front and rear traveling base 10 at the center thereof, and is coupled to the flange of the arbor 12 before It is rotatably supported on the after-traveling base 10, the passenger seat 40 is placed in the seat rotating plate 20, the front and rear running base 10 and the seat rotating plate 20 is a coupling ring 28 Bolted to.

The embodiment includes a rotation lock means for controlling the rotation of the seat rotating plate 20, which is inserted from the main body in accordance with the energization of the solenoid 23, the solenoid 23 supported by the bracket 22 Armature 24, a link 26 pivoting in a vertical direction about pivot axis 25 as the armature 24 moves, and a penetration formed at the end of the link 26 and formed in the seat rotating plate 20. The ball 20a has a lifting member 27 that moves up and down in the vertical direction.

The link 26 is rotatably coupled in a vertical direction about a pivot axis 25 whose center is supported by the bracket 22 and has a long groove 24a formed in the armature 24 of the solenoid 23. The link 26 is slidably coupled to the armature 24 to reciprocate the lifting member 27 in the vertical direction while the link 26 rotates in the vertical direction about the pivot axis 25.

Furthermore, the present invention includes a seat rotation lever 30 for controlling the rotation of the seat rotation plate 20, the seat rotation lever 30 is extended from the lever portion 31 and the lever portion 31 vertically The lever portion 31 includes a vertical portion 32 that is bent, a horizontal portion 33 that is bent horizontally from the vertical portion 32, and an inserting portion 34 that extends perpendicularly from the horizontal portion. ) And the insertion / detachment part 34 are formed at right angles, and the vertical part 32 and the insertion-and-department part 34 are arranged on the seat rotating plate 20 to be turned horizontally. In addition, the seat rotation lever 30 is elastically installed about the axis by the coil spring (35).

2, the horizontal portion 33 of the seat rotation lever 30 is positioned between the front and rear running base 10 and the seat rotating plate 20, the insertion and removal portion 34 is the front and rear Removably arranged in the locking groove 13 of the settable 12 provided in the running base 10 to be rotated horizontally around the pivot axis by the rotation of the seat rotation lever 30, as a result of the insertion part ( When the 34 is inserted into the locking groove 13, the seat rotating plate 20 is not rotated. On the contrary, when the inserting part 34 is separated from the locking groove 13, the seat rotating plate 20 can be rotated.

On the other hand, the seat rotation lever 30 is limited to the rotation by the above-described rotation lock means, referring to Figure 2 by the energization of the locking groove 13 and the solenoid 23 of the settable 12 The horizontal portion 33 of the seat rotation lever 30 is positioned between the lifting members 27 vertically lifting and lowering by the armature 24 to be inserted and removed. According to this configuration, the lifting members 27 are inferior. When positioned at the point, the horizontal portion 33 is sandwiched between the stand 12 and the elevating member 27 and cannot be turned. On the contrary, when the elevating member 27 is located at the top dead center, the pinching state is held. Since the seat rotation lever 30 can be rotated about the pivot shaft 25. Therefore, the insertion part 34 inserted into the locking groove 13 of the arbor 12 may be detached, and thus, the restraint of the seat rotation plate 20 is released, thereby allowing the rotation of the passenger seat 40.

In addition, an electric switch 36 electrically connected to the solenoid 23 is installed on the lever part 31 of the seat rotation lever 30, and the electric switch 36 is configured to rotate the seat rotation lever 30. When gripping, the contacts are electrically connected to energize the solenoid 23.

When the armature 24 protrudes due to the energization of the solenoid 23, the end of the link 26 pivots upwardly about the pivot axis 25, and at the same time, the elevating member 27 moves upward, so that the seat The restraint of the rotation lever 30 is released to allow the rotation to be free. This allows the seat rotation plate 20 to be rotated, and the seat rotation plate 20 is positioned in one of the front and rear directions. When the gripping state of the 30 is released, the energization of the solenoid 23 is interrupted and the lifting member 27 is lowered. Thus, the seat rotating lever 30 is the lifting member 27 and the rest table 12. It is sandwiched between and bound.

However, according to the above configuration, the electric switch 36 can be electrically connected to energize the solenoid 23 when the seat rotation lever 30 is gripped regardless of the state in which the vehicle is in progress or stopped. In the example, the solenoid 23 is energized in conjunction with the parking lever. That is, the circuit is designed so that the solenoid 23 can be energized only when the parking lever is in the parking state.

4 is a safety device for obstructing driving of the vehicle according to the position of the seat rotating plate 20 to enable driving in a state where the passenger seat is in a fixed position to secure a rear view through the side mirror while driving. It is for the safety of the passenger seated in the passenger seat. In addition, the circuit is designed so that the passenger seat can not rotate while driving.

Referring to the drawings, the first relay RY1 restricts the energization of the solenoid 23 by the electrical switch 36 connected to the ignition power line, and the second relay connected to the ignition power line to control the fuel pump. And a parking lever detection switch SW1 electrically connected to the first and second relays RY1 and RY2 to detect the position of the parking lever, and connected in parallel with the parking lever detection switch SW1. The seat position detection switch (SW2) for detecting the rotation position of the seat rotating plate 20 is electrically connected.

The parking lever detection switch SW1 is installed at a predetermined position of a parking lever (not shown) and detects the rotation state of the vehicle to detect a stopped state of the vehicle or a state before driving of the vehicle, and the seat position detection switch SW2 is By detecting the rotational state of the seat, that is, whether the passenger seat seat is facing forward or backward, the running of the vehicle is controlled in accordance with the power supply state of these detection switches SW1 and SW2. In other words, the parking lever detection switch SW1 and the seat position detection switch SW2 are designed as an AND circuit to cut off the power applied to the fuel pump M when one of the switches is turned off. Shut off fuel to the engine. In the figure, reference numeral D1 denotes a reverse voltage prevention diode.

According to this circuit configuration, when the seating lever 20, i.e., the passenger seat is rotated to the rear, the parking lever is switched to the driving state (D range or R range in the case of an automatic transmission, and the parking release state in the case of a manual transmission). In this state or the engine is stopped, the power applied to the fuel pump (M) is cut off, thereby interrupting the driving of the vehicle by blocking the fuel supplied to the engine, on the contrary, the parking lever in the parking state If it is, the front passenger seat can be freely rotated only when the vehicle is stopped or parked, such as starting the vehicle even if the seat turn plate 20 is facing backwards, and at the same time, fuel can be supplied to the engine. It is possible to drive only when the vehicle is facing, so that it can be caused by driving when the passenger seat is facing backwards. It is trying to prevent it.

In addition, since the parking lever detection switch SW1 is electrically shorted in a state in which the vehicle is running, that is, when the parking lever is disengaged, the electrical switch 36 provided in the seat rotation lever 30 is electrically connected. Even in the state, the solenoid 23 is not energized so that the passenger seat cannot be rotated.

If the parking lever is in the P-range while the vehicle is stopped, the parking lever detection switch SW1 is electrically connected. When the passenger seat is held by the seat rotation lever 30 to rotate the passenger seat, the electric switch ( As the 36 is connected, the solenoid 23 is energized to rotate the passenger seat.

As described above, the present invention has a configuration in which a control device is installed to detect the direction of the passenger seat and the parking lever position so that the seat can be rotated and the vehicle is driven. According to an embodiment, the vehicle is driven only when the passenger seat is facing forward. This makes it possible to prevent accidents that may occur by traveling when the passenger seat is facing backwards.
