The upper plate 42 of the cable link support bracket 40 configured as described above is hinged by the cable link hinge shaft 45 while the inner surface of the cable link 60 is interviewed, and the cable link hinge shaft 45 is described above. On one side of) is a return spring 46 for the cable link which is a means for providing an elastic force to the cable link 60. That is, one end of the cable spring return spring 46 is fitted to the cable link hinge shaft 45 fixedly attached to the cable link support bracket 40, and the other end is connected to the cable link 60. When the force applied to the front recliner lever 51 or the center recliner lever 55 disappears while the cable link 60 is operated, the cable link 60 is configured to return to its original state.

In particular, the rear surface of the cable link 60, the user to operate the two-touch recliner lever to release the rear catch unit 70 in the process after the first stage stroking the cable link 60 at the angle A stopper 63 is formed to protrude so that the operating force of the recliner lever can be transmitted, and the stopper 63 is used for supporting the above-mentioned cable link within the first stroke angle range of the two-touch recliner lever 50. The upper plate 42 of the bracket 40 is to be caught in the state.

That is, the rear catch release in the process in which the front recliner lever 51 and the center recliner lever 55 are rotated within the first stroke range by the stopper 63 protruding from the rear side of the cable link 60. The cable link 60 to which the upper end of the cable 65 is connected is configured to be inoperative.

Since the front recliner lever 51 is formed to protrude toward the front of the vehicle on the side of the double folding seat 20, the above-described center may be used to try reclining at the rear side of the double folding seat 20. The lower end of the reclining lever 55 is coupled to the front end of the rear recliner lever 59, the outer end of which is exposed toward the rear of the double folding seat 20 by a hinge. The rear recliner lever 59 may be formed of a cloth member.

That is, when the rear recliner lever 59 exposed to the rear of the double folding seat 20 is pulled instead of operating the front recliner lever 51, the center recliner lever 55 moves the pivot point. As the reference is rotated, the first stage stroking angle (17 °) is rotated, and if it is pulled continuously, if the full stroking the second stage stroking angle (34 °) is operated, the front recliner lever 51 is operated. As in the case, the back folding of the seat back 23 and the double folding of the seat cushion 22 are configured. Of course, even in this case, when the double folding seat 20 is full-backed when the rear recliner lever 59 is back folded, the double folding seat 20 may be double folded.

The lower end of the rear catch release cable 65 is connected to the rear catch unit 70 for double folding of the double folding seat 20, and the front catch unit 74 is provided with a second spiral spring 75. The structure is that the structure of the double folding sheet described in the description of the prior art can be applied as it is.

The operation process of the two-touch recliner lever configured as described above will be described below.

In order to perform the back folding or the double folding of the double folding seat 20, the user rotates clockwise on the front recliner lever 51 drawing or pulls the rear recliner lever 59 backward.

If the front recliner lever 51 is rotated by one stage of stroking angle, the rotational force of the front recliner lever 51 is transmitted to the back folding shaft 33, and the back folding shaft ( 33 is rotated and the locking means provided in the cam housing 36 is released, thereby limiting rotation of the seat back 23 counterclockwise on the drawing due to the restoring force of the first spiral spring 35. The seat back 23 is folded back while being released. If the user pulls the two-touch recliner lever 50 into the first stage stroking section at the rear of the rear double folding seat 20, the center recliner lever 55 connected to the rear recliner lever 59 is provided. Is rotated counterclockwise in the drawing, the pin 57 of the center recliner lever 55 transmits a force to the long hole 53 of the front recliner lever 51, so that the front recliner 51 Rotate clockwise on the drawing. Therefore, even if the user pulls the rear recliner lever 59 from the rear of the double folding seat 20 by the first streaking section, the same as when the front recliner lever 51 is rotated by the first strake angle. The operation is made.

At this time, one side of the lower end 55c of the center recliner lever 55 is in contact with the operating end 62 of the cable link 60. The cable link 60 is initially maintained in a rear catch. The unit 70 does not transmit the operating force.

On the other hand, if the user wants to carry out double folding continuously immediately after the back folding of the double folding seat 20, the front recliner lever 51 or the rear recliner lever 59 up to two stages of stroking section. Full stroking.

The front recliner lever 51 continues to rotate clockwise in the drawing while the front recliner lever 51 and the center recliner lever 55 are fully stroked with one stage of stroking. The recliner lever 55 rotates in a counterclockwise direction to rotate the cable link 60 in a state of being caught in the lower end of the center recliner lever 55. The cable link 60 rotates while winning the elastic force of the return spring 46 for the cable link, and pulls the upper end of the rear catch release cable 65 connected to one side thereof.

Therefore, the rear latch 71 is released from the striker 72 as the actuation force of the two-touch recliner lever 50 is transmitted to the rear catch unit 70 through the rear catch release cable 65. In this way, the restoring force of the second spiral spring 75 provided in the front catch unit 74 is transmitted to the seat frame 21 while the rear catch unit 70 is released, thereby seating the seat cushion 22. Double folding of the seat frame 21 is to be made.

On the other hand, when the cable link 60 is not rotated by the set angle, that is, when the rear catch release cable 65 is not full stroked, the rear catch unit 70 is set so as not to be released. The front recliner lever 51 or the rear recliner lever 59 does not operate at the correct single stage stroking angle (or section), but the first stage stroking angle (or section) and the second stage stroking angle (or section). What is necessary is just to perform the operation | movement which rotates or pulls in the range between.

In particular, the double folding of the double folding sheet 20 is not performed at the same time as the back folding and the double folding, but is performed in the state where the back folding has already been performed.

Even if the seat back 23 of the double folding seat 20 is in the state of the back folding, the front recliner lever 51 and the center recliner lever 55 are formed by the return spring 47 for the center recliner lever. By the restoring force, the angle is initially set.

In order to double fold the double folding seat 20 while the user is already back folded, the front recliner lever 51 or the rear recliner lever 59 should be full stroked. Even if the front recliner lever 51 or the rear recliner lever 59 is full stroked, the interlocking means of the cam housing 36 is already released, and the seat back is back folded by the restoring force of the first spiral spring 35. As a state, the operation when the first stage stroking is performed is omitted and only the operation by the second stage stroking is performed.

That is, one side of the lower end portion 55c of the center recliner lever 55 is caught by the operating end 62 of the cable link 60, and the cable link 60 is rotated, and the cable link 60 is set at an angle. When the rear catch release cable 65 is fully stroked by the rotation, the latch 71 of the rear catch unit 70 is released from the striker 72. The subsequent double folding process is as described above.

Therefore, in the double folding sheet 20 to which the present invention is applied, it is possible to immediately perform double folding even in a state in which the seat back having already been back folded is not raised as in the case of the prior art.

According to the present invention configured as described above, since the section operated by rotating or pulling the front recliner lever or the rear recliner lever is divided into a first stage stroking section and a second stage stroking section, the back folding has already been performed. When the double folding sheet is intended to be double folded, the recliner lever is operated in the full stroke range in the back folded state without the seat back in the original position, unlike the technique introduced in the prior art description. There is a huge advantage that double folding can be performed relatively simply.
