The seat plate unit 100 serves to support the hip of the seated person, and the backrest frame 20 serves to support the backrest of the seated person sitting on the seat plate unit 100. [

In particular, the seated person can change the position of the seat panel unit 100 with a good sitting feeling by, for example, tilting the backrest frame 20 or the like.

In order to realize this, the seat plate unit 100 includes a lower plate 110, an upper plate 120, and a front and rear advanced portion 200.

The lower plate 110 is connected to the backrest frame 20. Thus, the lower plate 110 is fixed in position.

The upper plate 120 is disposed on the upper side of the lower plate 110 and is movable forward and backward by an external force.

Of course, the lower plate 110 and the upper plate 120 can be changed in various shapes and various materials.

The forward and backward moving parts 200 allow the forward and backward movement of the upper plate 120 by the operation of the lower exposed portions of the lower plate 110 and induce the movement of the upper plate 120 to be stopped do.

The front and rear working part 200 includes a communication hole part 210, a guide rib 220, a slider 230, a grip 240 and a setting part 250.

The communication hole portion 210 is formed in a through hole in the upper plate 120. At this time, the size and the number of the communication hole portions 210 are not limited.

The guide ribs 220 protrude from both sides of the upper plate 120 along the edge of the communication hole 210. Of course, the guide rib 220 can be deformed into various shapes.

Further, the slider 230 is disposed between the facing guide ribs 220, and both sides thereof are guided along the corresponding guide ribs 220, and are moved forward and backward. The slider 230 can be deformed into various shapes.

The grip 240 extends from the slider 230 and protrudes forward from the lower side of the upper plate 120. Thus, the seated person can move the slider 230 through the operation of pulling the grip 240. At this time, the grip 240 can be deformed into various shapes and can be integrally formed on the slider 230. The upper plate 120 may be formed with a hole to guide the grip 240 in a downward direction.

The setting unit 250 sets the position of the upper plate 120 to allow the upper plate 120 to move forward and backward with respect to the lower plate 110 by moving the slider 230 by the operation of the grip 240 And set it to be fixed.

The setting unit 250 includes a slide stopper 251, a vertical hole 252, a recessed groove 253, a slope rib 254, and a stopping groove 255.

The slide stopper 251 is provided inside the communication hole portion 210.

The vertical hole portion 252 is formed in the communication hole portion 210 so as to guide the slide stopper 251 in the vertical direction. Of course, the communication hole portion 210 itself may be the vertical hole portion 252. Accordingly, the slide stopper 251 can reciprocate only in the vertical direction along the vertical hole portion 252.

The recessed trench 253 is recessed on the upper surface of the lower plate 110 to restrict the forward and backward moving distance of the slide stopper 251 protruding downward from the upper plate 120 through the vertical hole 252 . Particularly, even if the slide stopper 251 rises as much as possible along the vertical hole 252, the slide stopper 251 is partially exposed to the lower side of the upper plate 120.

The upper plate 120 can be moved back and forth with respect to the lower plate 110 until the slide stopper 251 comes into contact with one side of the depressed trench 253 and comes into contact with the other side. Of course, the upper plate 120 can be limited in its forward and backward moving distance with respect to the lower plate 110 by another configuration.

In particular, the depressed trench 253 serves to guide the slide stopper 251 to reciprocate in a straight line.

In addition, the slope ribs 254 are sloped on one side or both sides of the slide stopper 251.

Then, the slide stopper 251 is connected to the slope rib 254. Thus, when the slider 230 is moved forward or backward while the slide stopper 251 is fixed in the front-rear direction, the slide stopper 251 moves upward or downward along the slope rib 254 .

The stopping groove portion 255 is recessed in the recessed groove portion 253 along the forward and backward moving direction of the upper plate 120 so as to be spaced apart from each other by a predetermined distance.

The slide plate 251 is moved downward and is accommodated in the optional stopping groove portion 255 so that the upper plate 120 is moved .

On the contrary, when the slide stopper 251 moves up and moves away from the stopping groove portion 255, the upper plate 120 is allowed to move.

At this time, the seat occupant can pull the slider 230 through the grip 240 with one hand while pushing the upper plate 120 forward or pushing it backward.

Particularly, in a state in which the slider 230 is advanced, when the slide stopper 251 is detached from the stopping groove portion 255, the slider 230 can be easily moved back to the initial position.

One end of the elastic member 234 is engaged with the first fitting protrusion 235 protruding from the upper plate 120 and the elastic member 234 is inserted into the first fitting protrusion 235, And the other side of the slider 230 is fitted in the second fitting protrusion 237 protruded to the lower side of the slider 230.

Therefore, when the slider 230 moves back and forth with respect to the upper plate 120, the elastic member 234 resiliently assists the movement of the slider 230.

In addition, a cushion member 130 is provided on the upper plate 120. Accordingly, the slide stopper 251, which is raised when the seated person pulls the grip 240, is forcibly lowered along the slope rib 254 by the load of the cushion member 130 and the seated person and the self-load upon removal of the external force. As a result, the slider 230 moves to the initial position, and the slide stopper 251 is accommodated in the corresponding stopping groove portion 255.

On the other hand, the slider 230 may be limited in the forward and backward moving distance with respect to the upper plate 120.

To this end, the upper plate 120 protrudes the first knob 122, and the slider 230 has a rectangular first slot hole portion 232 receiving the first knob 122 so as to limit the moving distance, do. At this time, the long diameter of the first slot hole portion 232 is equal to or similar to the plane distance of the slope rib 254.

[ Respectively. The upper side of the first fastening member 102 contacts the slider 230 so that the slider 230 is prevented from being arbitrarily detached from the upper plate 120. Here, the first fastening member 102 is assumed to be a bolt.

Of course, the first slot hole portion 232 and the first knob 122 correspond to each other one-to-one, and the number is not limited.

Further, the movement distance of the upper plate 120 in the forward and backward directions relative to the lower plate 110 may be limited.

The upper plate 120 protrudes the second knob 124 and the lower plate 110 includes a rectangular plate 122 which receives the second knob 124 to restrict the moving distance of the upper plate 120. [ 2 slot-hole portion 112. [0053] That is, the upper plate 120 is reciprocally moved on both sides of the inside of the recessed groove portion 253 in contact with the slide stopper 251, or on both sides of the interior of the second slotted hole portion 112 in contact with the second knob 124 .

The second knob 124 exposed through the second slotted hole 112 is fixed to the lower surface of the lower plate 110 in order to prevent the upper plate 120 from being separated from the upper side of the lower plate 110. [ Respectively. The upper plate 120 is prevented from being detached from the lower plate 110 at random by contacting the head portion of the second fastening member 104 to the lower plate 110. [ Here, the second fastening member 104 is assumed to be a bolt.

In addition, the cushion member 130 stacked on the upper plate 120 is formed by recessing the deformation-permitting groove portion 300 so as to increase the amount of deformation when the seat is seated to improve the seating feeling. That is, the deformation-allowing groove portion 300 is formed in the corresponding portion of the cushion member 130 where the load of the seated person is concentrated, so that the cushion member 130 has a feeling of seating feeling .

In particular, the deformation-permitting groove portion 300 can be concentrated in a portion supporting the hip where the load of the seated person is concentrated and a portion supporting the thigh. Of course, the size and the number of the deformation-allowing grooves 300 are not limited.

In addition, the cushion member 130 is covered with the covering member 140 for protection. The cover member 140 is coupled to the upper plate 120 in various manners such as fitting or bolt.
