Following diagram of circuit and Figure 20 A～Figure 20 S according to Figure 19 describes the action of taking in of the 2nd back seat 15.In addition, though when vehicle seat used electric stowing system 20 is moved, left and right sides back of seat 22,23 and about rest the head on 24,25 equally the action, but at this for the ease of understanding, only left back of seat 22 and left side headrest 24 are described, omit explanation right back of seat 23 and right headrest 25.

At first, describe according to the diagram of circuit shown in Figure 19 action of taking in the 2nd back seat 15.

ST10: open the afterbody car door, press the seat control button, connect and take in switch.

ST11: the locking of the mechanism that unlocks, use back of seat to dump forward by spring force.

ST12: after back of seat is locked in the position of leaning forward, remove the locking of seat cushion.

ST13: seat cushion is swung to the car body rear.

ST14: the 2nd back seat (seat cushion and left back of seat) is accommodated in the housing recess of floor.

Below, particularly the action shown in the above-mentioned diagram of circuit is described according to Figure 20 A～20S.Figure 20 A is corresponding with the ST10 of Figure 19, and Figure 20 B～Figure 20 I is corresponding with ST11, and Figure 20 J～Figure 20 M is corresponding with ST12, and Figure 20 N～Figure 20 R is corresponding with ST13, and Figure 20 S is corresponding with ST14.

Shown in Figure 20 A, user 240 opens the afterbody car door 241 that car body 19 rear portions are possessed at first upward.By opening afterbody car door 241, connect afterbody car door opening switch (not shown).Then, press with finger 242 rear that is arranged on the 2nd back seat 15 seat control button 26 take in switch 26a, make its connection.

In Figure 20 B, the control unit 42 shown in Figure 20 A drives the CD-ROM drive motor 80 that a left side automatically locks releasing portion 196 according to controlling from the connection signal of taking in switch 26a.Because the driving of CD-ROM drive motor 80, lifting shaft 203 are moved downwards as shown by arrow A.

Because lifting shaft 203 moves, draw the 2nd interior hawser 208 of the 2nd hawser 201 as shown by arrow B by connecting strap 207 downwards.

In Figure 20 C,,, upwards draw hawser 194 in the 1st as shown by arrow B via connecting portion shown in Figure 15 200 by drawing the 2nd interior hawser 208 (with reference to Figure 20 B) of the 2nd hawser 201.

Owing to upwards draw hawser 194 in the 1st as shown by arrow B, last swing arm 188 as shown by arrow C, more than pin 189 is that the center rotates.Whereby, middle swing arm 184 as shown by arrow D, is the center rotation with intermediate pin 185 by the manipulation pin 186 in the embedded hole 187.

In Figure 20 D, the leading section 184a of middle swing arm 184 leaves the leading section 182a of lower swing bar 182, pushes the tab 182b of lower swing bar 182 with the intermediate cam face 184b of middle swing arm 184.

By the tab 182b of pushing lower swing bar 182, lower swing bar 182 is the center rotation with downside pin 183 as shown by arrow E, and the lock gear 181 of lower swing bar 182 is lifted upward.Whereby, lock gear 181 and the 1st being meshing with each other of gear 178 are disengaged, thereby remove the lock-out state of left lockout mechanism 56.

Because removed the lock-out state of left lockout mechanism 56, plate 177 is that topple over to car body the place ahead as shown by arrow F at the center by the spring force that is arranged on the disc spring (spring of curling up) 243 on the left bank setting device 50 with rotary shaft 176.At this moment, by last swing arm 188, locking disconnection detection switch 77 becomes on-state.

Above-mentioned disc spring 243 is springs identical with the common spring that uses for back of seat is dumped forward, and omits its detailed description.

In Figure 20 E, if the locking disconnection detection switch 77 shown in Figure 20 D becomes on-state, then control unit 42 (with reference to Fig. 3) is controlled according to this connection signal, and the CD-ROM drive motor 80 that makes a left side automatically lock releasing portion 196 is stopped the rotation.Whereby, keep down draw the 2nd hawser 201 the 2nd in the state of hawser 208.

In addition, even locking disconnection detection switch 77 breaks down, if magnet 204 arrives Hall element 82 down, then descend Hall element 82 to detect magnet 204, the control unit 42 foundations detection signal of Hall element 82 are down controlled, and make CD-ROM drive motor 80 rotations.Whereby, prevent lifting shaft 203 excessive descent, can protect CD-ROM drive motor 80.

Shown in Figure 20 F, if plate 177 dumps forward, then push the detector switch 76 that leans forward by cam 192, make it become on-state.

In Figure 20 G, control unit 42 (with reference to Fig. 3) drives it according to the left CD-ROM drive motor 80 that automatically locks releasing portion 196 of connection signal control of the above-mentioned detector switch 76 that leans forward, and lifting shaft 203 moves up as shown by arrow G.

If lifting shaft 203 rises to assigned position, magnet 204 arrives goes up Hall element 81, then goes up Hall element 81 and detects magnet 204.Above-mentioned control unit 42 stops the rotation CD-ROM drive motor 80 according to the detection signal of last Hall element 81.Whereby, remove the downward tensile force of the 2nd interior hawser 208 of the 2nd hawser 201.

In Figure 20 H, owing to removed the downward tensile force of the 2nd interior hawser 208 of the 2nd hawser 201 shown in Figure 20 G, so last swing arm 188 is by the spring force of extension spring 191, above as shown by arrow H pin 189 is the center rotation.Whereby, push manipulation pin 186 in the embedded hole 187 as shown by arrow I by last swing arm 188.Middle swing arm 184 is the center rotation with intermediate pin 185 as shown by arrow J, pushes the leading section 182a of lower swing bar 182 downwards by the leading section 184a of middle swing arm 184.

Owing to push the leading section 182a of lower swing bar 182 downwards, the lock gear 181 of lower swing bar 182 and 179 engagements of the 2nd gear.Therefore, left lockout mechanism 56 becomes lock-out state, and plate 177 remains on the position that dumps forward.

Shown in Figure 20 I, left back of seat 22 is poured into the position P3 that leans forward with plate 177.Owing to make left lockout mechanism 56 (with reference to Figure 20 H) become lock-out state, so left back of seat 22 becomes the state that is locked in the position P3 that leans forward.

Shown in Figure 20 H, because middle swing arm 184 is the center rotation with intermediate pin 185 as shown by arrow J, so locked closed detector switch 75 becomes on-state.

In Figure 20 J, if locked closed detector switch 75 (with reference to Figure 20 H) becomes on-state, then control unit 42 (with reference to Fig. 3) makes 70 actions of cushion lock power element according to this connection signal, and the traction control bar 172 as shown by arrows.Whereby, ratchet 169 is center swing with pawl axis 171 shown in arrow K.

Shown in Figure 20 K, the locking plate 169a of ratchet 169 leaves the lock pawl 167b of latch hook 167, and the lock-out state of latch hook 167 is disengaged.Simultaneously, by pin 165, locking/release detector switch 71 becomes on-state via pin 165.

In Figure 20 L, if locking/release detector switch 71 (with reference to Figure 20 K) becomes on-state, then control unit 42 stops cushion lock power element 70 (with reference to Figure 20 J), simultaneously, the seat cushion of control wobble drive mechanism 35 drives it with CD-ROM drive motor 65.

Drive with CD-ROM drive motor 65 if drive seat cushion, then left bolster 31 is just changeing, and is locked under the state of the position of leaning forward at left back of seat 22, and seat cushion 21 is swung to the car body rear from seating position P1 shown in arrow M.

In Figure 20 M, the support 166 of left cushion lock mechanism 36 rises with seat cushion 21 (with reference to Figure 20 L) shown in arrow M, and the latch hook 167 that is arranged on the support 166 also rises.

Because latch hook 167 rises, the following 167c of the formation engagement groove 167a of this latch hook 167 interferes with lock ring 107, and latch hook 167 is that the center rotates with lock hook shaft 168 shown in arrow N.

Shown in Figure 20 N, latch hook switch 72 becomes on-state, and simultaneously, the engaging of latch hook 167 and lock ring 107 is thrown off, and the locking of left cushion lock mechanism 36 is disengaged.

Control unit 42 (with reference to Fig. 3) is controlled according to the connection signal of latch hook switch 72, makes 70 actions of cushion lock power element, releases joystick 172 shown in arrow P.

Ratchet 169 is middle mind-set anticlockwise direction swing with pawl axis 171 shown in arrow Q, and the camming surface 169b of ratchet 169 is compressed against on the camming surface 167d of latch hook 167.Whereby, latch hook 167 can be remained on the position that lock ring 107 deviates from from engagement groove 167a.

Shown in Figure 20 P, owing to removed the locking of left cushion lock mechanism 36, seat cushion 21 is the center, continues to swing to the car body rear shown in arrow M with left and right sides bolster 31,32.At this moment, control unit 42 detects the motor current of seat cushion with CD-ROM drive motor 65, judges whether detected value has surpassed threshold value.Interfere with obstacle (not shown), when the motor current value surpasses threshold value, seat cushion stopped the rotation with CD-ROM drive motor 65 at for example seat cushion 21.

When seat cushion 21 is not interfered with obstacle, because the motor current value is littler than threshold value, so, can make seat cushion 21 continue shown in arrow M, to swing to the car body rear.

At this, as shown in Figure 5, owing on right bolster 32, set up spring 121, so along with seat cushion 21 moves to reception position P2 from seating position P1, the screen resilience of spring 121 increases shown in arrow Fo1 gradually.Therefore, shown in Figure 20 P, seat cushion 21 near the seating position P1 in the scope of plumb position P4, the screen resilience Fo1 of spring 121 is less.Whereby, the seat pad can make seat cushion 21 swing to the car body rear from seating position P1 swimmingly shown in arrow M with CD-ROM drive motor 65.

In Figure 20 Q, make seat cushion 21 swing to plumb position P4, make seat cushion 21 continue shown in arrow M, to swing to the car body rear from plumb position P4.

When seat cushion 21 was positioned at scope from plumb position P4 to reception position P2, the deadweight of seat cushion 21 and left back of seat 22 was towards the directive effect that makes seat cushion 21 swings.

On the other hand, by on right bolster 32, having set up along with seat cushion 21 is swung to reception position P2, the spring 121 (with reference to Fig. 5) that screen resilience Fo1 increases gradually guarantees that the screen resilience Fo1 of the spring 121 when seat cushion 21 is crossed plumb position P4 and swung to reception position P2 is bigger.Therefore, can offset the deadweight of seat cushion 21 and left back of seat 22 with the elastic force Fo1 of spring 121.Therefore, can make seat cushion 21 shown in arrow M, swing to reception position P2 from plumb position P4 swimmingly.

Shown in Figure 20 R, seat cushion 21 swings to the car body rear swimmingly, is accommodated in the floor housing recess 16.At this moment, the rear surface of left side headrest 24 is against on the upper end 16b of the rear wall 16a that constitutes floor housing recess 16.Whereby, as shown by arrows, load Fo3 is applied to the rear surface of left side headrest 24, overcomes the spring (not shown) of supporting left side headrest 24, folding left side headrest 24 shown in arrow R.Under this state, seat cushion 21 continues to swing to the car body rear shown in arrow M.

Shown in Figure 20 S, left back of seat 22 is against on the bottom surface 16c of floor housing recess 16.At this moment, because seat cushion uses the motor current value of CD-ROM drive motor 65 to surpass threshold value, so seat cushion stops the rotation with CD-ROM drive motor 65.

By above operation, the operations that seat cushion 21 and left back of seat 22 (the 2nd back seat 15) are accommodated in the floor housing recess 16 finish.

Below, according to diagram of circuit shown in Figure 21 and Figure 22 A～Figure 22 F the homing action that is accommodated in the 2nd back seat 15 (with reference to Fig. 1) in the floor housing recess 16 is described.

At first, briefly the homing action of above-mentioned the 2nd back seat 15 is described according to diagram of circuit shown in Figure 21.

ST20: open the afterbody car door, press the seat control button, connect reset switch.Whereby, seat cushion is swung to car body the place ahead.

ST21:, make left back of seat leave seat cushion making seat cushion when predetermined angular has been swung in car body the place ahead.

ST22: with cushion lock at reset position.

Below, particularly the homing action shown in the above-mentioned diagram of circuit is described according to Figure 22 A～Figure 22 F.Figure 22 A is corresponding with the ST20 of Figure 21, and Figure 22 B is corresponding with ST21, and Figure 22 C～Figure 22 F is corresponding with ST22.

In Figure 22 A, at first, user 240 opens the afterbody car door 241 that car body 19 rear portions are possessed upward.Owing to opened afterbody car door 241, afterbody car door opening switch (not shown) becomes on-state.

Then, the reset switch 26b that presses the seat control button 26 at the rear that is arranged on the 2nd back seat 15 with finger 242 is with its connection.

Control unit 42 drives the seat cushion CD-ROM drive motor 65 (in addition with reference to Fig. 2, Fig. 3) of wobble drive mechanism 35 according to the connection signal of reset switch 26b.Whereby, making seat cushion 21 shown in arrow S, is the center with left and right sides bolster 31,32,, takes out in floor housing recess 16 to the swing of car body the place ahead with left back of seat 22.

By in floor housing recess 16, seat cushion 21 and left back of seat 22 being taken out together, left side headrest 24 is discharged from the rear wall 16a of floor housing recess 16.Left side headrest 24 resets to the use location shown in Figure 22 B.

In Figure 22 B, seat cushion 21 continues to swing to car body the place ahead.

At this, as illustrated with Figure 20 Q, by on right bolster 32, being provided with along with seat cushion 21 is swung to reception position P2, the spring 121 (with reference to Fig. 5) that screen resilience Fo1 increases gradually guarantees that the screen resilience Fo1 of the spring 121 when seat cushion 21 is crossed plumb position P4 and swung to reception position P2 is bigger.

Therefore, when reception position P2 swings to plumb position P4, can offset the deadweight of seat cushion 21 and left back of seat 22 at seat cushion 21 by the screen resilience Fo1 of spring 121.Whereby, can make seat cushion 21 shown in arrow S, swing to plumb position P4 from reception position P2 swimmingly.

Shown in Figure 22 C, owing to seat cushion 21 is swung to car body the place ahead shown in arrow S, so seat cushion 21 is near seating position P1.

In Figure 22 D, the top 167e of the formation engagement groove 167a of latch hook 167 is against on the lock ring 107.Under this state, the support 166 of left cushion lock mechanism 36 and latch hook 167 descend shown in arrow S with seat cushion 21 (in addition with reference to Figure 22 D).Upwards pushed away by lock ring 107 owing to form the top 167e of engagement groove 167a, so latch hook 167 be that the center rotates with lock hook shaft 168 shown in arrow U.

Shown in Figure 22 E, if seat cushion 21 resets to seating position P1 (with reference to Figure 22 F), then latch hook 167 turns back to latched position, and latch hook switch 72 becomes off-state.If latch hook switch 72 becomes off-state, then the control unit shown in Figure 22 A 42 is controlled, and the seat cushion of wobble drive mechanism 35 is stopped the rotation with CD-ROM drive motor 65.So far, the homing action of the 2nd back seat 15 finishes.

Like this,, can the 2nd back seat 15 be accommodated in the floor housing recess 16 the electricity consumption flowing mode according to vehicle seat used electric stowing system 20, and, also can make it reset to the use location from floor housing recess 16.

At this, when making seat cushion 21 turn back to seating position P1, seat cushion 21, specifically the bottom 166a of support 166 is against on the leading section 163 that constitutes the last push part 162 of pushing mechanism 145 on the left seat cushion.

But, because the leading section 163 of last push part 162 bears the spring force that rises with spring 146, so, when seat cushion 21 is against on the leading section 163 of push part 162, be applied to the power of the leading section 163 of push part 162, be absorbed by the elastic deformation of rising with spring 146.Whereby, can prevent from when making seat cushion 21 turn back to seating position P1, floor 12 to be applied bigger power.

In addition, the leading section 163 by last push part 162 is against on the bottom 166a of support 166, rises with the spring force Fo2 of spring 146 directive effect towards arrow, and this spring force Fo2 upwards pushes away seat cushion 21, away from floor 12.Therefore, even when the occupant is not sitting on the seat cushion 21, latch hook 167 and left lock ring 107 also can engage reliably, for example, can make the disappearance of shaking between latch hook 167 and the left lock ring 107.

Shown in Figure 22 F, because seat cushion 21 remains on the state that is stabilized in seating position P1, so, can eliminate when motor-driven vehicle going, owing to latch hook 167 (with reference to Figure 22 E) and left lock ring 107 interfere the chatter that produces.

Below, according to Figure 23 A～Figure 23 C other assembling example of vehicle seat used electric stowing system is described.

In Figure 23 A, on the bottom 98,99 left and right sides L bracket 250,250 is being installed respectively about seat cushion 21.
