DEVICE FOR LOCKING A JUMP SEAT TO VEHICLE BODY}

The present invention relates to a locking device for a vehicle jump seat, and more particularly, by installing a locking device composed of a striker and a latch instead of deleting the leg of the jump seat, the weight of the seat is reduced and the concentrated load is applied to the vehicle body. And a jump device for locking a vehicle jump seat which can be prevented from being injured due to the departure of the jump seat during a crash by dispersing the jump seat hinge.

Cars are equipped with front seats and rear seats, and many seats are installed in multi-seater vehicles such as RV cars. These seats consist of a seat cushion, which is a part where the occupant sits, and a seat back, which is a part of which the back is leaned. In some cases, a headrest that can rest against the head and rest above the seat back is provided to be pulled upward. 1 shows a two-row jump seat mounted to an RV vehicle.

A seat holder 6 is provided on the floor 2 that provides space in the cabin together with the body 4, which is a fixed type consisting of a seat cushion 8 and a seat back 10 for two passengers to sit. The sheet is installed. On the other hand, one side of the fixed seat is provided with a jump seat consisting of a seat cushion 14 and a seat back 16 to be stored in a folded state as necessary to allow the passenger sitting on the rear row seat to ride down.

The seat cushion 14 of this jump seat is rotatably fixed to one end by a hinge 12 and the other end is supported by a leg 18. In addition, these seats are provided with a plurality of fastening buckle 22, 24, 26, 28 for fastening the seat belt.

Conventional vehicle jump seats having such a configuration are not provided with a separate fixing device on the outside of the jump seat, and are fixed only by the hinge of the jump seat, and in particular, the rear seat position in the seat seat belt attachment test, which is a domestic certification test, Since a two-point seat belt is installed, the test load is concentrated on the hinge of the jump seat. As such, when the concentrated load acts on the hinge part, the jump seat is separated and there is a problem that the passenger is fatally injured due to the departure of the jump seat in a crash accident.

In order to solve the above problems, the present invention reduces the weight of the seat by deleting the leg supporting the jump seat in the rearward position of the two-row rotary seat, and installs a striker, which is a locking device of the jump seat, on the body and cushions the seat. Locking device for the vehicle's jump seat that prevents breakage of the jump seat by preventing the breakage of the jump seat by installing a latch fixed to the striker to distribute the load to the hinge parts of the body and the jump seat. The purpose is to provide.

Locking device for a vehicle jump seat of the present invention for achieving the above object is a vehicle jump seat that is rotatably mounted to the fixed seat by a hinge, rotatable by a pin at one end of the seat cushion rotated around the hinge The latch is installed to the vehicle body by means of a latch and a fixing bracket, the latch is engaged at one end and the striker is provided with a stopper at the other end, and is engaged with the stopper while moving up and down along the lock guide attached to the vehicle body. And a cable for releasing the striker by releasing the engagement with the stopper so that the lock is pulled when the seat cushion is rotated by the operation of the latch release lever.

Hereinafter, with reference to the accompanying Figures 2 to 4 will be described in detail with respect to the locking device for a vehicle jump seat according to a preferred embodiment of the present invention.

Figure 2 is a front view showing the structure of a jump seat according to the invention, Figure 3 is an enlarged cross-sectional view showing a locking device employed in the present invention, Figure 4 is a plan view of the locking device of FIG.

First, as described with reference to FIG. 1, a seat holder 6 is provided on the floor 2, and a fixed seat including a seat cushion 8 and a seat back 10, in which two passengers can sit, is installed. It is. On the other hand, one side of the fixed seat is provided with a jump seat consisting of a seat cushion 14 and a seat back 16 to be stored in a folded state as necessary to allow the passenger sitting on the rear row seat to ride down.

The seat cushion 14 of this jump seat is rotatably fixed to one end by a hinge 30, and the other end is fixed to the vehicle body 4 by the locking device of the present invention. The locking device is composed of a striker 44 largely rotatably mounted on the vehicle body 4 side and a latch 52 rotatably mounted on the seat cushion 14 side, the detailed structure of which is shown in FIG. It is.

Referring to FIG. 3, the overall configuration of the jump seat locking device according to the present invention includes a striker 44 and a pin 54 that are pivotally mounted to the vehicle body 4 by a fixing bracket 58. A latch 52 rotatably mounted at one end of the 14, a lock 38 for releasing the vertical fixed state of the striker 44, and a lock guide 42 for guiding the shank movement of the lock 38; And a cable 34 for activating the lock 38 at the return of the seat cushion 14 to release the striker 44 from being fixed.

Here, one end of the seat cushion 14 is rotatably supported by the hinge 30, and the other end is provided so that the latch 52 can rotate by the fixing pin 54. As shown in FIG. This lock 38 is partially open to allow striker 44 to engage or disengage from this opening.

On the other hand, at one end of the striker 44, a stopper 46 which is engaged with the lock 38 and maintains the vertical solid state is formed. As can be seen more clearly in FIG. 4, the striker 44 has a substantially U shape, one end of which is engaged with the latch 52 as described above, while the other end thereof is fixed by the fixing bolt 50. It is rotatably provided by the fixing bracket 58 attached to the vehicle body 4. On the other hand, the fixed bracket 58 is fixed to the vehicle body 4 so as to press one end of the striker 44 to rotate the striker 44 when the lock 38 and the stopper 46 are disengaged. The return spring 48 which is accommodated in (4) is further provided.

2 again, at one end of the cable 34 for pulling the lock 38 to release the lock state from the stopper 46, the seat cushion 14 returns to its original position to maintain the horizontal state. ) Is further provided with a return spring 40 which presses so as to be raised to engage the stopper 46. A cable arm 32 is formed at the other end of the cable 34, and the cable arm 32 is fixed to the bracket 32.

In the jump seat provided with the locking device of such a configuration, when the seat is turned, the latch opening lever 56 is first operated to rotate the latch 52 clockwise. Accordingly, the latch 52 is detached from the striker 44 while the seat cushion 14 is folded while being rotated along the arrow direction P1 about the hinge 30 when the seat cushion 14 is lifted up. All. Next, the striker 44 may be rotated along the arrow direction P1 ′ and pushed into the receiving groove formed in the vehicle body 4 in a vertical state.

At this time, as the striker 44 is rotated in a vertical state, one end of the stopper 46 moves on the top inclined portion of the lock 38, and when the pass through the end point of the inclined portion is pressed, the return siphon 40 is pressed. By rising again and engaging with the stopper 46, it is possible to maintain the fixed state of the striker 44 as it is.

When the seat cushion 14 is unfolded again for the passenger to sit, when the seat cushion 14 is rotated in the direction of the arrow Q1, the cable 34 is pulled to compress the return spring 40, thereby The lock 38 pressed by the return spring 40 is pulled downward along the lock guide 42. As a result, the locked state of the lock 38 and the stopper 46 is released, so that the striker 44 stored in the vehicle body 4 is rotated along the arrow direction Q1 'by pressing the return spring 48. While maintaining the horizontal state, the latch 52 fixed to one end of the seat cushion 14 is engaged with the striker 44 in the horizontal state it is possible to firmly maintain the fixed state of the seat cushion 14.

According to the present invention described above, by removing the legs supporting the jump seat to reduce the weight of the seat, while installing a striker which is a locking device of the jump seat on the vehicle body, by installing a latch fixed to the striker on the cushion side, By dispersing to the hinge portion of the body and the jump seat to prevent breakage of the jump seat there is an advantage that can prevent the damage of the passengers due to the departure of the jump seat in the event of a crash.
