Description

[Detailed description of the invention] The present invention relates to an improvement of a switch for an electric tilting device that automatically raises or topples a reclining seat. Specifically, the invention automatically detects the rising or falling position of a reclining seat. This relates to a switch for setting an appropriate position.

Conventionally, a switch for an automatic tilting device for a reclining seat has been installed on a reclining seat 1 as shown in FIG.
A block 3, 4.5 is attached to the drive arm 2 that rotates the switch lever 6.7.
The detector was fixed so that 8 was engaged.

Then, as the reclining seat 1 rotates, the drive arm 2 rotates, and the block 3.4.5 of the drive arm 2 rotates.
are engaged with the switch levers 6, 7, and 8 of the detector to turn on and off a drive circuit (not shown) in which the detector is interposed.
The reclining seat 1 was automatically stopped at the forward tilting position (for getting in and out of the rear seat), the driving position, and the rearward tilting position.

However, such a switch cannot be used in block 3 due to the fixed position of the detector. 4. There was a drawback that the size of 5 became large and it was impossible to miniaturize it.

Furthermore, since the detector and blocks 3, 4.5 were fixed, the inclination of the reclining seat could not be adjusted, making it impossible for tower occupants to set the optimum operating position.

Furthermore, there is a drawback that the detector itself is expensive and the switch as a whole is also expensive.

The present invention was devised to eliminate the above-mentioned problems, and provides a switch for an automatic tilting device that is small in size, inexpensive, and allows tower occupants to freely set the position of the reclining seat.

The embodiments of the present invention will be described above based on the drawings.

Figures 2 and 3 show an embodiment of the present invention.
Reference numeral 1 denotes a reclining seat, and 2 a drive arm that adjusts the raising and lowering of the reclining seat 1, which is rotated by an electric motor of a drive circuit (not shown).

Reference numeral 13 denotes a band-shaped conductive plate attached to the end surface 9 of the drive arm 2, and is attached concentrically to the rotation center of the rotating arm 2.

10, 11, and 12 are holes bored in the conductive plate 13.

A connector 14 is integrally molded with relay plates 15, 16, and 17 embedded therein, and is held movably in the tangential direction of the conductive plate 13 by an adjustment screw 18.

One end of the relay plate 15, 16, 17 is connected to the drive arm 2.
As it rotates, it comes into sliding contact with the conductive plate 13, and the other end is connected to a drive circuit (not shown).

Next, the operation will be explained.

In order to overturn the reclining seat 1 in the direction A in FIG. 2, the drive circuit connected to the relay plate 15 is turned ON to rotate the drive arm 2.

At this time, the relay plate 15 is in sliding contact with the conductive plate 13 and supplies current to the motor via the conductive plate 13.

When the reclining seat 1 comes to a predetermined position as the drive arm 2 rotates, the reclining plate 15 falls into the hole 10 formed in the conductive plate 13 and the drive circuit is cut off. The rotation of the reclining seat 1 also stops, and the reclining seat 1 becomes in a constant overturning state.

Further, when the reclining seat 1 is raised in the direction B in FIG. 2, the same operation as described above is performed by turning on the drive circuit of the relay plate 17.

Further, when the drive circuit of the relay plate 16 is turned on, the reclining seat 1 stops at the operating position.

Therefore, the holes 10, 11, 12 of the conductive plate 13 are formed on the sliding contact locus of the relay plates 15, 16, 17,
It is large enough to break the connection with the relay plates 15, 16, and 17.

On the other hand, if the position of the connector 14 is changed using the adjustment screw 18, the stop position of the drive arm 2 will shift by θ0 as shown in FIG. 3, so the stop position of the reclining seat 1 can be adjusted by changing the position of the connector 14. can.

As detailed above, the reclining seat switch according to the present invention has a drive circuit composed of a conductive plate attached to a drive arm and a relay plate that is in sliding contact with the conductive plate, and a connection made by integrally molding a plurality of relay plates. Since it is a device, it can be made into a small and simple switch structure.

Furthermore, the number of lead wires that conventionally required two lead wires can be reduced to one.

Furthermore, by changing the position of the connector, the passenger can freely set the position of the reclining seat desired by the passenger.
