Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an iIJ rear rotation adjustment device for an axle rear seat.

Before the present invention was proposed, the rear seats of sedan-type or hard-type vehicles were divided into two or three parts on the left and right sides, and the seats could be reclined or adjusted separately using a lifter. It was not publicly known that this could be done.

In other words, most of the rear seats of known sedan-type or hard-top-type vehicles are fixed.

Furthermore, in the case of reclining adjustment devices, the reclining adjustment can only be performed overall, not to the left or right side.

Therefore, when attempting to adjust the recline of a conventional sedan or hardtop rear axle seat, the consent of the passenger in the adjacent seat is required, and adjustments can only be made after obtaining consent. , I couldn't adjust it even if I wanted to, unless I could get the consent of the passenger sitting next to me.

Therefore, the present invention divides a conventional sedan-type or /\-top-type axle rear seat into at least two parts on the left and right sides, and makes it possible to adjust each divided rear seat separately. This prevents the defects of the known examples mentioned in iii.

The present invention provides a structure in which the rear seat of a sedan type or hardtop type vehicle is provided with a rear seat at the rear of the front seat, and the rear seat is divided into two or more parts on the left and right sides, and each part can be rotated back and forth separately. a front and rear axle rear seat front and back rotation adjustment device, and a sedan type or hard top type axle with a rear seat provided at the rear of a front V6, the rear seat of the axle is divided into two or more on the left and right sides, and each is separately formed. In the longitudinal rotation adjustment device for a rear seat of a vehicle configured to rotate back and forth, the divided rear seats not only rotate back and forth separately, but also simultaneously rotate back and forth integrally. and a vehicle in which the rear seat of a sedan-type or hard-top type axle with a rear seat provided at the rear of the front seat is divided into two or more parts on the left and right sides, and each part is configured to move forward and backward separately. In the rear seat longitudinal adjustment device, when a specially provided switch is operated, the position of one of the divided rear seats is set as a reference (thus, the other divided rear seats are adjusted to match that position). The gist is the configuration of the device as described above, which moves and forms a horizontal line to form an integrated seat.

A reduction spring 33 is attached between them.

The detection roll 24 is formed to protrude further outward than the protrusions 31 and 32 and engage with the V-shaped cut groove 20. A position detection plate 19° formed similarly to the detection plate 19 and a switch mechanism 21' are attached to the junction 18' between the moderation 3 and the row seats 4. 22' is an upward movement switch, and 23' is a downward movement switch.

Figure 6 is a wiring diagram, and 34 is an interlocking switch that switches between interlocking operation (position b) and independent operation (position a).

The switches 35, 36, 36, 4, 4, 4, 4, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, , , and, numeral 35, numeral 35, numeral 2, the upper movement switch, numeral 36, the lower movement switch, numeral 37, the upper movement switch, and numeral 38, the lower movement switch, respectively. Also, Fig. 7 is a wiring diagram of the split rear seat 1 in Figs. 1 and 2, where 39 is an interlocking changeover switch provided at an arbitrary position, 40 is the same interlocking changeover switch, and 41 is an upper movement switch of seat 2. , 42 is a downward movement switch for the control 2, 43 is an upward movement switch for the medium 3, 44 is a downward movement switch for the same, 45 is an upward movement switch for the row seat 4, and 46 is a rotation cut-off switch.

Next, we will discuss the effect.

In the present invention, because of the above-described configuration, the changeover switch 34 is set to the sixth position.
If you manually switch to position a in the figure and turn on the upper movement switch 35 for the right seat 2, the motor 17' attached to the seat 2 will be energized, rotating the worm gear 16 and the gear 15. Then, the screw rod 10 screwed into the gear 15 is moved backward, the L stack rod 11 is rotated clockwise, and the frame 6 is moved downward about the shaft 8 of the reclining corner 9.

When the lower movement switch 32 is turned on, the motor 17' attached to the jig 2 is energized, the worm gear 16 is rotated, the gear 15 is rotated, and the screw rod 10 screwed into the gear 15 is rotated. It is moved forward, the L stacking rod 11 is rotated counterclockwise, and the frame 6 is moved down around the shaft 8 of the reclining corner 9.

When turning on the upper movement switch 37, the motor 17°' attached to the row seat 4 is energized, the worm gear 16 is rotated, the gear 15 is rotated, and the screw rod screwed into the gear 15 is turned on. 10, rotate the L stacking rod 11 clockwise, and move the frame 6 to the shaft 8 of the reclining corner 9.
Move seats 4 up around .

When the lower switch 38 is turned on, the motor 17°' attached to the row of seats 4 is energized, the worm gear 16 is rotated, the gear 15 is rotated, and the screw rod 10 screwed into the gear 15 is turned on. is advanced, the L stacking rod 11 is rotated counterclockwise, and the frame 6 is moved down around the shaft 8 of the reclining corner 9.

Next, in Fig. 6, move the changeover switch 34 to the position b, as indicated by the temporary line! ;7J M In other words, the upper movement switch 35 and the lower movement switch 36 are not configured with a circuit, so even if the upper movement switch 35 and the lower movement switch 36 are operated, the control unit 2 does not move at all.

However, when the upward movement switch 37 of the row seats 4 is turned on, the motor 17' is energized to move the row and row seats 4 upward, and the motor 17' of the carriage 2 can also be energized to move them together.

That is, turn on the E movement switch 37 of row 4 and turn left y;4.
When the switch mechanism 21 is moved upward, the switch mechanism 21 fixed to the row seats 4 is also moved upward, so that the state shown in FIG. 3 changes to the state shown in FIG. 4.

That is, in FIG. 3, the detection roll 24 is fitted into the V-shaped cut groove 20 of the position detection plate 19, so if the contact point 0 is switched to the position a shown by the solid line, each motor 17, motor 17" and the motor 17", currents for "-movement" or "downward motion" flow independently, so that the seats 2, the middle floor 3, and the rows of seats 4 move up and down independently.

Next, if only the interlocking changeover switch 39 is switched to position b Cq indicated by the dotted line, the same effect as in the explanation of FIG. 6 will result.
When you turn on the upward movement switch 41 and move the jig 2 up a little, the u of the position detection plate 19 located several times on the jig 2
Since the relative position between the J-included 1A 20 and the detection roll 24 is shifted as shown in Fig. 4, the push button 25 is pressed by the support arm 27 to turn on the switch 22, and at the same time, the motor 17 is energized, and the inner paste is interlocked. When the interlocking selector switch 4o for moving the seats 3 upward is switched to the temporary line position, the switches 22' of the switch mechanism 21' are similarly turned on to move the seats 4 at the same time.

When the lower switch 42 is turned on, the operation is the reverse of the above and operates in the same manner.

However, in FIG. 7, if the switches 39.4o are all set to the a position and the switch 39 is turned on, only the cloth layer 2 will move more and more downward, causing the position detection plate of the joint 18 to move downward. Both the switch mechanism 19 and the switch mechanism 21 are disengaged and become in the state shown in FIG.
2 is on and off.

For example, when the switch 39 is switched to the b position, the motor 17 is immediately energized and rotates forward, and the intermediate 3 moves upward, causing the roller 24 to engage with the cut groove 2o. It will stop automatically and the seats will be aligned.

For example, in the case of switch 4o, if it is switched to the position, the motor 17'° is immediately turned on, the motor 17'° rotates forward, the rows of seats 4 move upward, and the rollers 2
4 engages with the cut groove 20 and stops automatically, thus,
Row 4 will also be lined up.

The present invention is a sedan type or hard top type axle with a rear seat provided at the rear of the front seat. a front-rear rotation adjustment device for a rear seat on an axle; In the longitudinal rotation adjustment device 6 for a rear seat of a vehicle configured to rotate back and forth, the divided rear seats are configured to not only rotate back and forth separately, but also simultaneously rotate back and forth integrally. and a sedan-type or hard-top 2 vehicle with a rear seat provided at the rear of the front seat. In the axle rear seat longitudinal adjustment device, when the divided rear seat is operated with a specially provided switch, the position of the other divided rear seats is adjusted to match the position of one of the divided rear seats. Because of the structure of the above-mentioned device in which the rear seats are moved horizontally in a straight line to form an integrated seat, it is possible to move the rear seats forward and downward or to align them separately or simultaneously with a single switch mechanism.
