Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a warning device for a rotating automobile seat.

(Prior Art) Car seats, especially the driver's seat, must face forward correctly when driving.
The passenger seat and rear seats do not necessarily have to face forward, but they must be fixed when the vehicle is in motion.

(Problem to be solved by the invention) As mentioned above, one way to turn the seat in a direction other than the front is to attach the seat so that it can rotate freely so that it can be turned towards the door when getting on and off the vehicle. It is possible that This makes getting on and off the vehicle much easier. However, when the seat is rotatably mounted in this manner, a problem arises if the seat is not fixed to the vehicle body during driving. The present invention has been developed in view of this point, and is designed to issue a warning if the seat is not fixed at the start of travel or if it becomes unfixed during travel.

(Means for solving the problems) The present invention, as a means for solving the above problems,
An automobile rotating seat warning device is configured such that the central part of the Atsupa frame is rotatably attached to the lower frame on the vehicle body side in a horizontal plane, and the Atsupa frame is covered with a skin to form a seat part. In the rotary seat, U-shaped stopper holding fittings are installed at multiple locations sandwiching the central shaft attachment part of the upper frame, and on the other hand, the stopper holding fittings are attached to a portion of the lower plate facing the stopper holding fittings. A stopper pin is positioned so that the head is surrounded by the holding metal fitting, and the stopper holding metal fitting and the stopper pin are positioned so that they engage when the seat faces correctly forward, and the above-mentioned atsupah frame A lock lever with a notch in a part is biased toward the lock side by a spring and is rotatably attached to the lower frame, and a part of the lower frame corresponding to the notch is provided with a lock lever so that the seat faces correctly forward. A stopper pin that engages with the notch is installed, and a switch connected in series to the key switch is provided at a portion of the lower frame near the lock lever, so that the actuator of the switch moves depending on the posture of the lock lever to close the circuit. The lock lever is opened and closed, and the position is set so that the circuit is open when the seat correctly faces forward, and when the notch of the lock lever is disengaged from the stopper pin, the switch is activated. It is configured so that an alarm connected to the switch is activated.

(Function) With this configuration, when the seat is not fixed by the locking device or when the seat is unfixed midway through, an alarm such as a buzzer is activated,
Can warn you. The present invention not only provides a warning, but also allows the warning to be used to start the engine.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a seat, 2 is a seat portion thereof, and 3 is a backrest portion. The seat portion 2 is formed by covering the outside of the upper frame 4 with a skin through a cushion material, but this portion is not shown in the drawings. The upper frame 4 is roughly in the shape of a plate with an open top, and is rotatably attached to a lower frame 5 on the vehicle body side at its center via a shaft 6. As shown in FIG. 2, a bearing 7 is interposed on the shaft 6 to facilitate rotation. The structure for attaching the lower frame 5 to the floor panel of the vehicle body is such that the lower frame is slidably supported by two rails provided on the floor panel, and the seat is mounted so that its position can be adjusted in the longitudinal direction of the vehicle body. However, illustration of this part is omitted.

A hot pattern plate 8 having an arcuate planar shape and a roughly Z-shaped vertical cross section is attached to the lower part of the hot frame 4 by welding.On the other hand, a hot pattern plate 8 is attached to the upper part of the lower frame 5. The lower turn plate 9, which has almost the same shape as the pattern plate 8, is attached by welding to the hot pattern plate 8.
is engaged in. This prevents the seat 1 from tilting during rotation. Pins 10 are attached to the Atsupa frame 4 at symmetrical positions with the shaft 6 in between, pointing downward, so that when the seat 1 is rotated, the end of the lower turn plate 9 comes into contact with it at a predetermined angle. It is set as. This allows sheet 1
The rotation angle of is regulated. To install pin 10,
Although a nut is welded to the upper frame 4 and a bolt is screwed into the nut with a downward direction, other methods may be used.

A lock lever 11 is attached to the side of the Atsupa frame 4.
is rotatably mounted on a shaft 12.
As shown in FIG. 3, this lock lever 11 is provided with a notch 13, which engages with a stopper pin 14 that stands up from the lower frame 5 side. A spring 15 is stretched between a part of the lock lever 11 and the upper frame 4, and applies a force to the lock lever 11 in the direction in which the notch 13 always engages with the stopper pin 14.

As shown in FIG. 3, a switch 16 is attached near the lock lever 11, and an actuator 17 is made to face the lock lever 11. As a result, the switch 16 is opened and closed depending on the attitude of the lock lever 11. A buzzer 18 (not a buzzer, but a lamp or the like, or even both) is connected to the switch 16 by an electric wire 27, and when the switch 16 is closed, a battery 19 is connected as a power source.
(See Figure 8) A current flows through the pipe, producing a sound.

Atsupa frame 4 has U in two places sandwiching shaft 6.
A letter-shaped stopper holding metal fitting 20 is provided,
Stopper pin 21 planted from the lower frame 5 side
It is designed to surround and engage the head of the head. Note that this engagement is performed when the seat 1 is correctly facing forward. FIG. 4 shows the engaged state. 5 to 7 are a plan view, a side view, and a rear view of the seat portion 2 of FIG. 1. In FIG. 5, contrary to FIG. 1, the left side in the figure is the front. In these figures, the same members as in FIGS. 1 to 4 are given the same reference numerals to clarify their arrangement positions.

FIG. 8 shows an example of the connection of the switch 16. A movable contact 24 of a key switch 23 is connected to the battery 19 via a main fuse 22. The aforementioned buzzer 18 and switch 16 are connected in series to the fixed contact 25 of the key switch 23 via a fuse 26.

This device configured in this way has a switch 1
6, when installing notch 1 of lock lever 11.
The lock lever 11 and the stopper pin 14 are installed in such a way that the lock lever 11 and the stopper pin 14 are engaged when the seat 1 correctly faces forward. Fig. 9a shows the seat 1 facing diagonally toward the door with respect to the vehicle body (not shown, but the upper side of the figure is the front) for getting on and off, and Fig. 9b shows the seat 1 facing the front correctly for driving. It shows where you are heading.
In state a, the pin 10, which is displaced together with the upper frame 4, comes into contact with the end of the lower turn plate 9, and the angle is restricted so that it does not turn any further. When rotating the seat 1, the lock lever 11 is pulled so as to rotate clockwise in FIGS. 1 and 3 about the shaft 12, and the stopper pin 14 is disengaged from the notch 13. Once the seat 1 has rotated to a certain extent, you can release your hand from the lock lever 11.

The stopper holding fitting 20 provided at the lower part of the upper frame 4 engages with the stopper pin 21 when the seat 1 is properly facing forward as shown in FIG. 9b. In this case, since the stopper holding fitting 20 is shaped to surround the head of the stopper pin 21 as described above, it also acts to prevent the seat 1 from steadying in the vertical direction. When changing the seat 1 from the state shown in FIG. 9A to the state shown in FIG. If engaged correctly,
The switch 16 becomes open. Therefore, in FIG. 8, even if the movable contact 24 of the key switch 23 comes into contact with the fixed contact 25, the buzzer 18 does not sound, but the lock lever 11 is not locked to the stopper pin 14, or the lock is uncertain. Then, the buzzer 18 will sound to warn you. In addition, the movable contact 24 of the key switch 23
When the switch 16 is off, the buzzer 18 does not sound even if the switch 16 is closed.

When the buzzer 18 sounds, all you have to do is reset the lock. In the circuit shown in Fig. 8, the switch 16 is of a type that closes when the seat 1 is not locked or is incompletely locked. A circuit configuration is used that also has a special contact point, and connects it in series to the engine's ignition circuit to issue a warning when the seat 1 is not fixed or is incomplete, and to prevent the engine from starting. Good too. When the seat 1 is for something other than the driver's seat, the correct orientation is not necessarily only facing forward, but in any case, the mounting position of each member is set so that it is fixed during driving. do.

(Effects of the Invention) Since the present invention is configured as described above, it has the effect that a warning is issued by the alarm when the seat is not fixed at the start of travel.

Since the warning switch is connected in series with the key switch, this warning will not be issued when the vehicle exits the vehicle with the key switch turned off. Furthermore, when riding, if the lock lever is not set in the correct position, a warning will be issued when the key switch is turned on, allowing the occupant to reset the lock lever to the correct position.
