The guide plate 10, The rotation plate 20, and the rear link plate 30, respectively.

The guide plate 10 is formed as shown in Fig. 6 and is fastened to the seat bracket 3 which is the lower link L2. The guide plate 10 is provided with a rotating plate 20, a rear link plate 30, and the like, which will be described later.

A hinge connection hole 11 is formed in the guide plate 10 and a shaft (not shown) through which the recliner 5 is installed is inserted into the hinge connection hole 11, 20).

An arcuate guide slot 12 is formed around the guide plate 10. The guide slot 12 serves to guide the guide pin 40 during a dive operation of the seat.

Further, the guide plate 10 is formed with a rear link connection hole 13 for hinging the rear link plate 30. The rear link connection hole 13 is a center of rotation of the rear link plate 30 serving as a rear link L4 and a center point of the guide slot 12.

In addition, the guide plate 10 is provided with a link stopper 15 for restricting the rotation of the rear link plate 30, thereby limiting the rotation range of the rear link plate 30.

On the guide plate 10, a block plate 14 for limiting the rotation of the latch locker 55, which will be described later, is protruded. The block plate 14 is formed in an arcuate shape with respect to the hinge connection hole 11 of the guide plate 10 so that the rotation of the latch locker 55 is restricted so that the latch locker 55 restricts the latch 50 .

The rotating plate 20 is formed as shown in FIG. 7, is rotatably installed on the guide plate 10, is integrally fastened to the seatback frame 2a, and is connected to the recliner 5 , And rotates together with the seat back (2) when adjusting the angle of the seat back (2).

A hinge connection hole 21 is formed in the rotatable plate 20 so as to be rotatably connected to the guide plate 10. The rotary plate 20 and the recliner 5 are connected to each other by providing a shaft on which the recliner 5 for adjusting the angle of the seatback 2 is installed in the hinge connection hole 21. [

A guide pin slot 22 having an arc shape around the hinge connection hole 21 is formed around the rotating plate. Both ends of the guide pin slot 22 become the upper limit and the lower limit of the folding operation of the seatback 2, respectively. The guide pin 40 is positioned at the left end of the guide pin slot 22 and the guide pin 40 is guided by the guide pin 40 when the seatback 2 is fully folded forward. And is located at the right end of the pin slot 22.

The latching plate 20 is provided with a latch connecting hole 23 and a locker connecting hole 24 for mounting a latch 50 and a latch locker 55 to be described later, A latch block 25 is also formed.

The rear link plate 30 is installed on the guide plate 10 so as to be rotatable with a radius smaller than that of the rotatable plate 20. As shown in FIG. 8, the rear link plate 30 includes a hinge mounting hole 31 at one side thereof, a guide pin through hole 32 at the opposite side thereof, Is rotatably installed on the guide plate (10) by using the guide plate (31).

The rear link plate 30 serves as a rear link L4 and restrains the movement of the cushion seat frame 1a, that is, the upper link L1 until the folding completion of the seat back 2, And moves the upper link L1 from the dive switching point to the completion point of the dive operation.

That is, the rear link plate 30 selectively engages with the rotating plate 20, and when the seat back 2 is folded, the rotating plate 30 is rotated independently of the stationary rear link plate 30, The rear link plate 30 rotates together with the rotating plate 20 from the dive switching point of the seatback 2 until the completion of the dive.

On the other hand, the hinge attachment hole 31 of the rear link plate 30 is in contact with the locking lever 35 or the link stopper 15 formed on the guide plate 10, A stop surface 33 is formed symmetrically with respect to each other so as to restrict rotation. That is, since the rear link plate 30 rotates about its lower end, the stop surface is formed to face downward in the drawing. When the stopper surface (33) comes into contact with another component, the rear link plate (30) is restricted from rotating.

The rotation of the rear link plate 30 in one direction, that is, in the direction in which the seat back 2 is tilted backward (clockwise in Figs. 5A and 5C) is restricted by the link stopper 15, A locking lever 35 is provided to lock the rotation. The locking lever 35 is rotatably provided on the guide plate 10 so as to be elastically supported toward the rear link plate 30 and one end of the locking lever 35 protrudes from the stop surface of the rear link plate 30, The rear link plate 30 can be restrained or released by abutting or releasing the rear link plate 30. [ That is, the other end of the locking lever 35 is brought into contact with or removed from the stopper surface 33 of the rear link plate 30 by using the actuator 36, which is the restraining releasing means, The rear link plate 30 is constrained when one end of the locking lever 35 contacts the stop surface 33 of the rear link plate 30 and the other end of the locking lever 35 is engaged with the stop surface 33 of the rear link plate 30. [ The restraint of the rear link plate 30 is released.

As described above, when the locking lever 35 restrains the rear link plate 30, since the rotation of the rear link plate 30 is restricted, even if the seat back 2 folds, the cushion seat 1 moves Restrain things. When the locking lever 35 releases the restraint of the rear link plate 30, the rear link plate 30 is in a state of being rotatable. Therefore, during the dive operation of the seatback 1, (30) rotates to push the cushion seat frame (1a) to move the cushion seat (1) forward.

The guide pin 40 is inserted into the guide slot 12 of the guide plate 10, the guide pin slot 22 of the rotatable plate 20, and the guide pin through hole 32 of the rear link plate 30 So that the guide plate 10, the rotating plate 20, and the rear link plate 30 interlock with each other.

The guide pin 40 is in a state in which the guide pin 40 is not moved in the folding section where the seatback 2 is folded and the angle of the seatback 2 is adjusted (between the state of FIG. 4 and the state of FIG. 10) (Between the state of FIG. 10 and the state of FIG. 12) in which the cushion seat 1 is moved forward while being shifted to the dive operation, The guide plate 10, the rotating plate 20, and the rear link plate 30 are interlocked with each other.

The latch 50 is rotatably mounted on the rotatable plate 20 so that the latch 50 can restrict the rotation of the guide pin 40 during the folding of the seat back 2 And the guide pin 40 is held in a restrained state from the dive switching point of the seatback 2 to the completion of the dive operation.

One end of the latch 50 is rotatably hinged to the rotatable plate 20 and the other end thereof is opened to receive the guide pin 40. The pin receiving portion 51 is formed in a U-shaped planar shape so that the latch 50 can confine the guide pin 40 during a dive operation. The end of the pin receiving portion 51 is connected to the side where the guide pin 40 is inserted, that is, the side of the seatback 2, in which the guide pin 40 can be easily received into the pin receiving portion 51. [ It is preferable that the length of the forward folded side is short. A stopper surface 52 is formed around one end of the latch 50 to restrict the rotation of the latch 50 only within a predetermined range by engaging with the latch block 25 formed on the rotating plate 20 . In addition, the latch 50 is installed so as to be elastically supported so as to face the guide pin 40.

The latch locker 55 is provided to restrict the rotation of the latch 50 and maintain a limited state. The other end of the latch locker 55 is rotatably mounted on the rotation plate 20 while being supported by the rotatable plate 20 in the direction of the latch 50. The other end of the latch locker 55 is engaged with the stop surface 52 of the latch 50 Thereby restricting rotation of the latch 50 in a direction in which it is elastically supported.

The latch locker 55 is elastically supported so that the latch locker 55 does not restrict the rotation of the latch 50 when the latch 50 is in operation, The block plate 14 is interposed between the latch lockers 55 and the latch locker 55 is in a state in which the latch 50 can not be restrained. 5D, since the latch locker 55 does not restrict the latch 50 during folding of the seat back 2, the block plate 14 of the guide plate 10 is not engaged with the latch 50. Therefore, The rotation of the locker 55 is limited, thereby preventing the latch locker 55 from rotating toward the latch 50.

During the dive operation of the seatback 2, as shown in FIGS. 11D and 13D, the rotating plate 20 provided with the latch locker 55 rotates in one direction (counterclockwise in the drawing) The block plate 14 formed on the guide plate 10 has an effect of relatively rotating in a direction opposite to the rotating direction of the rotating plate 20, The latch locker 55 restrains the latch 50 from the dive switching point to the dive completion point.

Hereinafter, the operation of the fold-and-dive seat of a vehicle according to the present invention will be described with reference to the accompanying drawings.

The operation of the fold-and-dive seat according to the present invention can be divided into two sections, that is, a folding section in which the seatback 2 is folded, and a dive section in which the cushion sheet 1 moves forward by dive switching of the seatback 2. That is, between the state shown in FIG. 4 and the state shown in FIG. 10 corresponds to the folding section, and the state between the state shown in FIG. 10 and the state shown in FIG. 12 corresponds to the dive section. The cushion sheet 1 does not interfere with the seat back 2 in the folding section and the cushion seat 1 does not change its position while the seat back 2 is folded.

Fig. 4 is an initial state or folding section in which the seat back 2 is partially inclined, the cushion seat 1 is in the correct position (not moved forward), and the portion indicated by "A" The state is the same as that shown in Fig.

5A and 5B, when the seat back 2 is rotated in the folding section, the rotating plate 20 integrally fastened to the seat back 2 together with the seat back 2 rotates.

The rotation pin 20 is rotatable about a shaft provided with the recliner 5 at the lower end and the guide pin 40 is rotatable about the rotation of the guide pin slot 22 The guide pin slot 22 and the guide pin 40 are not constrained to each other, or the operation is not restricted.

Therefore, the occupant can rotate the seat back 2 at a desired angle, and the position of the cushion seat 1 is not moved even if the angle of the seat back 2 is adjusted.

Further, as shown in Fig. 5C, the rear link plate 30 does not operate even when the rotating plate 20 rotates.

5d, while the seat back 2 is folded, the latch locker 55 is locked by the block plate 14 located between the latch 50 and the latch locker 55, The pin 50 is prevented from being constrained and the pin 50 is also separated from the guide pin 40 so that the pin 50 may be inserted into the pin receiving portion 51 of the guide pin 40, Nor is it accepted.

Therefore, the passenger is allowed to rotate in the folding section until the guide pin 40 is positioned in the section between the state shown in Fig. 4 and the state shown in Fig. 10, that is, at the left and right ends of the guide pin slot 22, Can rotate freely, so that the seat back 2 can be rotated at a desired angle.

10, when the folding of the seat back 2 is completed, the rotating plate 20 rotates and the guide pin 40 is positioned at one end of the guide pin slot 22 (FIGS. 11A and 11B) See Fig. The guide pin 40 is positioned at an intermediate portion of the guide pin slot 22 other than both ends of the guide pin slot 22 so that the guide pin 40 does not affect the rotation of the rotating plate 20 And the angle of the seat back 2 fastened to the rotating plate 20 can be changed.

On the other hand, when the seat back folding is completed and the guide pin 40 is positioned at one end of the rotating plate 20 (right end as viewed in FIG. 11B) in a state of switching to the dive operation, , The rotating plate 20 starts to operate the guide pin 40 and enters the dive section. That is, FIG. 10 shows a state in which folding of the seat back is completed and the dive operation is started at the dive switching point. 11A and 11B, when the rotating plate 20 further rotates counterclockwise, the guide pin 40 is inserted into the guide pin slot 22 of the rotatable plate 20 The guide pin 40 and the rotating plate 20 continue to move along the direction in which the rotating plate 20 rotates.

When the rotating plate 20 and the guide pin 40 start rotating together, the guide pin 40 rotates the rear link plate 30 (see FIG. 11C), and the cushion sheet 1 And starts to move forward. The upper end of the rear link plate 30 or the portion to which the guide pin 40 is connected is connected to the rear end of the upper link L1 integrally formed with the cushion seat 1, The cushion seat 1 starts to move forward when the rear end of the upper link L1 starts to be pushed forward.

11C, in order for the rear link plate 30 to rotate, a control unit (not shown) operates the locking lever 35 through the restraining releasing means so that one end of the locking lever 35 The rear link plate 30 is released from the stop surface 33 of the rear link plate 30 so that the rear link plate 30 is rotatable.

That is, when the folding of the seat back 2 is completed, in order to move the cushion seat 1 forward, the actuator 36 rotates the locking lever 35 through a separate button operation or the like, The locking lever 35 releases the restraint of the rear link plate 30.

In addition, when the rotatable plate 20 operates the guide pin 40, the guide pin 40 is held by the latch 50, Thereby supporting the guide pin 40. That is, when the rotating plate 20 rotates, the latch 50 is restrained by the latch locker 55 so that the latch 50 can support the guide pin 40. The latch 50 and the latch locker 55 provided on the rotating plate 20 are rotated together with the rotating plate 20 but the block 50 is interposed between the latch 50 and the latch locker 55, The plate 14 is formed on the fixed guide plate 10. The rotation of the rotatable plate 20 is thus caused by the fact that the block plate 14 interposed between the latch 50 and the latch locker 55 is relatively moved in a direction opposite to the rotating direction of the rotatable plate 20 It means that the latch locker 55 can restrain the latch 50. As shown in FIG.

The rotation of the cushion seat 1 and the seat back 2 is continued and the cushion seat 1 and the seat back 2 are in the states shown in Figs. 12 and 13A. When the cushion seat 1 and the seat back 2 are in the state shown in Fig. 13A, The dive operation of the cushion sheet 1 is completed and the cushion sheet 1 is moved forward and lowered from the initial state.

In this state, the rotating plate 20 is rotated to the maximum with respect to the guide plate 10 (refer to FIG. 13B) and reaches the maximum with the rear link plate 30, L1 and L2 are moved forward and downward (see FIGS. 12 and 13C), the latch 50 is rotated in a state in which the guide pin 40 is locked and the rotating plate 20 and the rear link plate 30 is operated and the latch 50 is also held by the latch locker 55 (see FIG. 13D).

As described above, according to the fold-and-dive seat of the vehicle according to the present invention, in the conventional art, the seat of the vehicle is folded and diced in a four-bar link structure to adjust the angle of the seat back 2, 1, the rear link L4 and the lower link L2 are spaced apart from each other and connected to each other through the guide plate 10, the rotating plate 20 and the rear link plate 30, The adjustment of the angle of the cushion sheet 2 and the movement of the cushion sheet 1 can be operated in a state of being divided for each section.

Therefore, since the cushion sheet 1 does not move while the angle of the seat back 2 is adjusted by separating the movement of the cushion seat 1 from the adjustment of the angle of the seat back 2, Can be set.
