The first gear 150 and the second gear 160 are seated on the seating portion 130a of the gear lever 130, and the first gear 150 is seated so as to be positioned above the second gear 160. After the shaft 170 is inserted into the through hole 151 of the first gear 150 and the through hole 162 of the second gear 160, the lower end of the shaft 170 is seated 130a. The fitting hole 132 is fitted to be coupled.

The second ground surface 134 of the gear lever 130 is provided with a gear lever operating cable 191 from the outside to lock the upper rail 102 in order to set the position of the seat to fit the passenger's body shape. And release the gear tooth 152 of the first gear 150 and the gear tooth 162 of the second gear 160 from the locking hole 101a of the low rail 101.

Subsequently, the locking lever 140 has a third support ground portion 141 having a third coupling hole 142 formed at one end thereof in a state in which the locking lever 140 is positioned above the gear lever 130. The engagement protrusion 134a of the second support ground portion 134 is fitted into the third coupling hole 142 so as to be in close contact with the inner side of the 134 (the surface facing the first support ground portion 113). In addition, the locking pin 143 formed at the other end of the locking lever 140 is placed on the upper surface of the first gear 150.

The locking pin 143 of the locking lever 140 is supported on the upper surface of the first gear 150, and the pinhole 153 of the first gear 150 and the pinhole 163 of the second gear 160 are When coincided with each other, the pinhole 153 of the first gear 150 and the pinhole 163 of the second gear 160 pass through the locking pin hole 133 of the gear lever 130. .

An operation of the memory device, which is the walk-in of the vehicle seat according to the exemplary embodiment of the present invention having the above configuration, will be described with reference to FIGS. 7 to 14.

First, the initial state of the walk-in memory device 100 is as follows. Here, the initial state refers to a state in which the upper rail 102 is locked to the low rail 101 so that the seat is not moved before the passenger gets on the seat and sets the seat position suitable for the passenger's body.

In this initial state, as shown in FIG. 8, the other end of the shield lever 120 provided with the support plane 122 is lowered by the elastic force of the first elastic body 180 so that the locking pin of the locking lever 140 143 passes through the pinhole 153 of the first gear 150 and the pinhole 163 of the second gear 160, and is then fitted into the locking pin hole 133 of the gear lever 130. In addition, the gear teeth 152 and the first gear 150 of the first gear 150 are coupled to the gear lever 130 that is elastically supported by the second elastic body 181 with respect to the first supporting ground portion 113 of the base member 110. The gear tooth 162 of the two gears 160 passes through the locking hole 102a of the upper rail 102 and is inserted into the locking hole 101a of the low rail 101. Of course, the latch 103a of the locking mechanism 103 is also inserted into the locking hole 102a of the upper rail 102 and the locking hole 101a of the low rail 101 to be in a locked state in which the seat is not moved.

In the initial state of the walk-in memory device 100 as described above, when the occupant manipulates an operation unit (not shown) to move the seat to fit his / her body shape, the latch 103a of the locking mechanism 103 rotates. As it is separated from the locking hole 102a of the upper rail 102 and the locking hole 101a of the low rail. At this time, as the operation cable 190 which is a work connected to the second ground surface part 134 of the gear lever 130 is pulled, the gear lever 130 is rotated about the second coupling hole 131. Then, the other end of the gear lever 130 to which the first gear 150 and the second gear 160 are coupled is rotated so that the first gear 150 that is fitted into the locking hole 101a of the low rail 101 is rotated. The gear tooth 152 and the gear tooth 162 of the second gear 160 are separated from the locking hole 101a of the low rail 101 as shown in FIG. 10. Then, the upper rail 102 is in a state in which the locking is released with respect to the low rail 101. At this time, the occupant stops the operation of the operation unit and locks the seat again after stopping the seat after moving the seat back and forth to fit its body shape.

After the seat is set according to the occupant's body in this way, in the locked state, after the occupant gets off the seat, the walk-in engraving part (not shown) is operated to operate the seat. Then, the operating force of the walk-in operation unit is transmitted to the support plane 122, which is the other end of the shield lever 120 by the work-in operation cable 190. Then, the shield lever 120 is rotated about one end and at the same time, the support plane 122, which is the other end, moves upward.

As a result, the locking pin 143 of the locking lever 140 fitted into the pinhole 153 of the first gear 140 and the pinhole 163 of the second gear 160 is separated. At this time, the gear tooth 152 of the first gear 150 and the gear tooth 162 of the second gear 160 pass through the locking hole 102a of the upper rail 102 to lock the hole of the low rail 101. It will be in the state fitted to 101a. That is, the pinhole 153 of the first gear 150 and the pinhole 163 of the second gear 160 communicate with each other, and the gear teeth 152 and 162 of the first and second gears 150 and 160 communicate with each other. Is inserted into the locking hole 101a of the row rail 101, and the workpiece becomes a walk-in memory state.

Here, when the work-in operation part is operated, the latch 103a which is the locking mechanism 103 of the seat is in a state of being separated from the locking holes 101a and 102a of the low rail 101 and the upper rail 102. As shown in FIG. 13, the locking surface portion 124 of the shield lever 120 blocks the locking hole 102a of the upper rail 102 so that the latch 103a is fitted into the locking hole 102a of the upper rail 102 to seat. Is prevented from being locked. In addition, the stopper 125 of the shield lever 120 catches one side of the other end of the gear lever 130 and prevents the gear lever 130 from being rotated by the elastic force of the second elastic body 181. ), The gear teeth 152 and 162 of the first and second gears 150 and 160 are prevented from falling out of the locking hole 101a of the low rail 101.

Afterwards, the occupant moves the seat forward and then gets on or off the back seat.

When the seat is moved forward, the first and second gears 152 and 162 are fitted into the locking holes 102a of the upper rail 102 and the locking holes 101a of the low rail 101. 150 and 160 move together with the upper rail 102 while rotating. When the first and second gears 150 and 160 rotate together with the upper rails 102, the pinholes 153 and the second gears 160 of the first gear 150 that are in communication with each other are connected. As the pinholes 163 are shifted from each other, the locking pins 143 of the locking lever 140 are maintained on the upper surface of the first gear 150.

The occupant then moves the seat back to its original position. Then, when the upper rail 102 is moved rearward with the seat, the first and second gears 150 and 160 rotate together with the upper rail 102 while rotating in the opposite direction that is rotated when the seat is moved forward. Is rotated. At this time, the gear teeth 152 and 162 of the first and second gears 150 and 160 are maintained in a state of being fitted into the locking hole 101a of the low rail 101.

In addition, the pinhole 153 of the first gear 150 and the pinhole 163 of the second gear 160 coincide with each other while the seat is moved backwards, and the carbon end portion of the shield lever 120 communicates with the first elastic body. It is descended by 180. Then, the locking pin 143 of the locking lever 140 interlocked with the shield lever 120 is inserted into the pinholes 153 and 163 communicated while being lowered by the elastic force of the first elastic body 180.

At this time, the gear lever 130, the rotation of which is prevented by the stopper 125 of the shield lever 120 is rotated about one end. As a result, the first and second gears 150 and 160 coupled to the other end of the gear lever 130 have all the gear teeth 152 and 162 fitted to the low rail 101 removed. In addition, as the locking surface portion 124 of the shield lever 120 is also lowered, the latch of the locking mechanism 103 is fitted into the locking hole 102a of the upper rail 102 and the locking hole 101a of the low rail 101. The upper rail 102 is locked to the low rail 101.

As such, the upper rail 102 is locked to the low rail 101 and the sheet is returned to its original position.

According to the present invention as described above, the seat after the work-in operation returns to the position where the seat was fixed before the work-in operation. Therefore, since the position of the sheet normally set by the user is continuously maintained even after the walk-in operation, a walk-in user memory is possible, and the user can freely set the return position after the walk-in of the sheet.

In addition, after the work-in, when the seat is returned to the rear, the seat is stopped and fixed accurately at the position set by the user, so that it is not necessary to readjust the position of the seat after the back of the seat, thereby improving user convenience.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and those skilled in the art to which the art belongs may have various modifications and equivalent other embodiments.
