Insertion rod 83,83 can be inserted in this patchhole 82,82.By the support (not shown) with pivot 85 with on the bending part 83a, the 83a that are rotatably coupled to these insertion rod 83,83 ends.

Strut bar 86 is fixed on the pivot 85.One of assembling is used to coil spring 87 that strut bar 86 is swung backward on pivot 85.The elastic force ground that overcomes coil spring 87 by retainer 88 remains on strut bar 86 on the P1 of use location.This retainer 88 is fixed on bending part 83a, the 83a.Head rest body 89 is fixed on the strut bar 86.

Shown in Fig. 4 B, when 24 the rear surface 24a of resting the head on to the left applied predetermined load, the front portion of elastic force ground around pivot 85 towards vehicle body that makes left headrest 24 overcome coil spring 87 was folded to folding position P2.

,, can expect taking a kind of like this structure herein as the method for folding left headrest 24, that is, and folding left headrest 24 when left seat back 22 is tilted forward.But, the structure of folding left headrest 24 when left seat back 22 being tilted forward in order to be formed on, as the member that Motion Transmission is extremely rested the head on that tilts forward that is used for back of seat, for example need to adopt such as the pivot 91 that departs from left seat back 22 (referring to Fig. 2, eccentric shaft Fig. 3) and this eccentric shaft is connected to members such as electric wire on the headrest, and described structure becomes comparatively complicated.Thus, can increase number of components and parts and increase the stack-mounted work capacity, want spended time that headrest 24 is installed simultaneously.

Thus, elec. vehicle seat storage system 20 of the present invention is so constituted, that is, the rear surface 24a of left headrest 24 and the rear wall 18 of floor recess 16 (referring to Figure 20 A) are abutted together, and 24 the rear surface 24a of resting the head on to the left apply predetermined load with folding left headrest 24.Therefore, owing to the axle and the such member of electric wire that need not such as the pivot 91 that departs from left seat back 22, so can simplified structure.Thus, by reducing number of components and parts and reducing the assembly working amount, time of setting up is shortened and raising output.

The mechanism that leans forward of the left headrest 24 shown in Fig. 4 A and Fig. 4 B only is an example, and to this without any restriction.In brief, the required left headrest 24 that just makes so constitutes, promptly, can apply predetermined load by 24 the rear surface 24a of resting the head on to the left left headrest 24 can be tilted forward, and can when elimination acts on load on the 24a of rear surface, make left headrest 24 be back to its use location.

Because the structure of right headrest 25 is identical with left headrest 24, so will omit explanation to it.

Fig. 5 shows the back of seat that is used for the electric stowing system of the seat according to the present invention mechanism that leans forward.This back of seat mechanism that leans forward has leaning device 40 and tripper 47.

Left side mechanism 40 has lockout mechanism 46, pivot 91, one-way damper 910, the sensing switch 66 that leans forward, locking ON sensing switch 65 and locking OFF sensing switch 67.

On pivot 91, be provided with one and be used to promote the coil spring 49 (referring to Figure 13 B) that back of seat 22 dumps forward.

Left side shown in Fig. 3 and right one-way energy disperser 910 are such energy disperser, promptly, its pooling feature can play a role when back of seat 22,23 tilts forward, and mild the tilting forward of realization back of seat 22,23, but when its forward-lean state was back to erectility, its pooling feature was inoperative at back of seat 22,23.

Can adopt the energy disperser that for example in JP-UM-A-6-80039, discloses as these one-way damper 910.The sort buffer device as shown in Figure 6.

Referring to Fig. 6, one-way damper 910 is by following component set-up: an energy disperser, second swivel 921 and a damper element that is arranged between first and second swiveies 920,921 that it has first swivel 920, is made of gear; The arm 922 that rotates with the rotation of second swivel 921; Friction lining between the lower end of second swivel 921 and arm 922, it is used for the rotation of second swivel 921 is passed to arm 922; Gear 923, it is installed to the upper end of arm 922 in rotating mode and is meshed with second swivel 921; First retainer 924 with gear parts; And second retainer 925.

When first swivel 920 rotates in the direction of arrow A, by damper element second swivel 921 is rotated in the direction of arrow A, and arm 922 is also rotated in the direction of arrow A.When this situation takes place, because gear 923 meshes with first retainer 924, gear 923 is stopped operating, and also make with gear 923 ingears second swivel 921 and stop operating.Thus, pooling feature with respect to first swivel 920 along the rotation of arrow A direction and come into force, thereby make described rotation mild.

When first swivel 920 rotated in the direction of arrow B, second swivel 921 and arm 922 also rotated in the direction of arrow B, but stopped the rotation of arm 922 by second retainer 925.Because gear 923 can freely rotate, so the rotation of second swivel 921 is not stopped.Therefore, the effect of energy disperser can be with respect to the directive effect of arrow B on first swivel 920.

To describe the operation of elec. vehicle seat storage system 20 according to Figure 11 to Figure 25 B below.When carrying out the operation of elec. vehicle seat storage system 20, a left side and right seat back 22,23 and a left side and right headrest 24,25 etc. are worked in an identical manner, herein, for the ease of understanding, to only discuss, and omission is to the explanation of right seat back 23 and right headrest 25 to left seat back 22 and left headrest 24 etc.

At first the operation of taking in that is used for the electric stowing system 20 of seat according to the present invention is described with reference to Figure 11 to Figure 20 B.

Figure 11 is for showing the diagram of circuit of taking in operation according to elec. vehicle seat storage system of the present invention (first embodiment).

Step (being subsequently abbreviated as ST) 01: shown in Figure 12 A, open tailgate 146 and press seat control switch 26 so that take in switch 37 connections.

ST02: open lockout mechanism and back of seat is tilted forward by elastic force.

ST03: when back of seat being locked in its position that dumps forward, remove cushion lock.

ST04: make the posterior rotation of seat cushion towards vehicle body.

ST05: second back seat (seat cushion and the right side and left seat back) is accommodated in the floor recess.

To the content of ST01 to ST05 be elaborated below.

Shown in Figure 12 A, user 145 upwards opens the tailgate 146 that is arranged on vehicle body 17 rear portions.Tailgate OPEN switch (not shown) is connected in opening of tailgate 146.Subsequently, that presses the seat control switch 26 that is arranged on after second back seat 15 with finger 147 takes in actuating element 26a, connects so that take in switch 37.

Detect after tailgate OPEN switch is in on-state the actuator 70 of the tripper 47 of left side shown in the application drawing 12B at control setup 36.The operation of actuator 70 moves downward lifting/lowering axle 114 shown in arrow a.By moving downward, lifting/lowering axle 114 spurs the inside cable 111 of connecting cable 110 shown in arrow b by attaching parts 118.

In Figure 13 A, when drawing the inside cable 111 of connecting cable 110 shown in arrow b, upside swing arm 102 clockwise rotates around upper pin 103 shown in arrow c.As a result, make the manipulation pin 100 in pilot hole 101 be subjected to making it to shift to the effect of the power in left side among the figure.Middle swing arm 98 rotates counterclockwise around intermediate pin 99 shown in arrow d.

Shown in Figure 13 B, the end 98a of swing arm 98 left the end 96a of downside swing arm 96 in the middle of the rotation of middle swing arm 98 made.Subsequently, the intermediate cam face 98b of middle swing arm 98 promotes the extension arm 96b of downside swing arm 96.Because the extension arm 96b of downside swing arm 96 is promoted, downside swing arm 96 rotates counterclockwise around lower pin 97 shown in arrow e, and promotes the lock gear 95 of downside swing arm 96.

Can make lock gear 95 and first gear, 93 de-meshs like this, and open left lock mechanism 46.When opening left lock mechanism 46 in this way, under the elastic force effect that is arranged at the coil spring 49 in the left side mechanism 40, plate 92 tilts forward around pivot 91 front portion towards vehicle body shown in arrow f.At this moment, as mentioned above, the pooling feature of the one-way damper 910 shown in Fig. 6 works, and plate 92 is verted forward lentamente.Subsequently, make locking OFF sensing switch 67 be in on-state by upside swing arm 102.

When shown in Figure 13 B, making locking OFF sensing switch 67 be in on-state by upside swing arm 102 like that, the connection signal of locking OFF sensing switch 67 is input to (referring to Fig. 3) in the control setup 36, and the actuator 70 of left side tripper 47 shown in Figure 14 is stopped.As a result, keep down the traction connecting cable 110 inside cable 111.

For example when in locking OFF sensing switch 67, going wrong, when magnet 115 arrives lower hall sensor 72 as shown in Figure 14, lower hall sensor 72 detects magnet 115, and control setup 36 makes it to stop according to the detection signal control actuator 70 from lower hall sensor 72.In this way, prevent that lifting/lowering axle 114 from descending excessively, thus protection actuator 70.

Shown in Figure 15 A, when plate 92 is finished when dumping forward,, and make it be in on-state by the cam 105 compressings sensing switch 66 that leans forward.Will be from the connection signal input control device 36 (referring to Fig. 3) of the sensing switch 66 that leans forward.This control setup 36 drives the actuator 70 of left side tripper 47 like that shown in Figure 15 B.Lifting/lowering axle 114 is upward movement shown in arrow g.

When lifting/lowering axle 114 has been increased to desired location and magnet 115 when having arrived the position of upper hall sensor 71, upper hall sensor 71 detects magnet 115.Control setup 36 stops actuator 70 according to the detection signal from upper hall sensor 71.So just, eliminated the downward tension force on the inside cable 111 that is applied to connecting cable 110.

Because eliminated the downward tension force on the inside cable 111 of the connecting cable shown in Figure 15 B 110, the elastic force of the extension spring 104 shown in Figure 16 A rotates counterclockwise upside swing arm 102 like that around upper pin 103 shown in arrow h.Thus, shown in arrow i, oppress manipulation pin 100 in pilot hole 101 by upside swing arm 102.Swing arm 98 clockwise rotated around intermediate pin 99 shown in arrow j in the middle of this made.The end 98a of middle swing arm 98 promotes the end 96a of downside swing arm 96 downwards.

The end 96a of the downside swing arm 96 that is pushed down makes the lock gear 95 and 93 engagements of first gear of downside swing arm 96.Thus, locking left lock mechanism 46 and plate 92 is held in its forwardly tipped position.

Shown in Figure 16 B, left seat back 22 dumps forward with plate 92 and moves to position P1, and the left lock mechanism 46 shown in locking Figure 16 A.Left seat back 22 is locked on the position P1 that dumps forward.

In Figure 16 A, because middle swing arm 98 rotates shown in arrow j around intermediate pin 99, locking ON sensing switch 65 is connected.

Referring to Figure 17 A, when control setup 36 (referring to Fig. 3) receives connection signal from the locking ON sensing switch 65 shown in Figure 16 A, cushion lock actuator 60 work, and joystick 140 is withdrawn as shown by arrows like that.Therefore, ratchet 138 rotates around detent pin 139 shown in arrow k.

In Figure 17 B, the rotation of ratchet 138 is thrown off the lock pawl 136a of its lock part 138a and breech lock 136, and opens breech lock 136.Simultaneously, by pin 149 release-push 61 is connected.

Referring to Figure 18 A, when control setup 36 received connection signal from the release-push 61 shown in Figure 17 B, control setup 36 stopped the cushion lock actuator 60 shown in Figure 17 A, and the driving motor 55 of driven in rotation device 30.The driving of driving motor 55 is rotated left side bolster 28a forward, and left seat back 22 is being locked under its locational situation that dumps forward, and makes seat cushion 21 with left seat back 22 posterior rotation to vehicle body shown in arrow m.

In Figure 18 B, the support 135 of left cushion blocking device 32 promotes with the seat cushion 21 shown in Figure 18 A like that shown in arrow m with being integral, and this makes breech lock 136 risings that are arranged on the support 135.

Because striker 142 is set at engaging groove 141 inside of breech lock 136, so the raising of breech lock 136 can make the downside 141a of engaging groove 141 and striker 142 produce interference, and breech lock 136 rotates around latch pin 137 shown in arrow n like that.

In Figure 19 A, latch switch 62 is connected, striker 142 breaks away from the engaging groove 141 of breech lock 136, and opens left cushion blocking device 32.

When control setup 36 (referring to Fig. 3) detected latch switch 62 connections, control setup 36 was operated cushion lock actuator 60 so that joystick 40 travels forward like that shown in arrow p.

Ratchet 138 rotates around detent pin 139 shown in arrow q like that, and the camming surface 138b of ratchet 138 is pressed on the camming surface 136b of breech lock 136.Therefore, breech lock 136 is remained on the position of striker 142 and engaging groove 141 disengagings.

In Figure 19 B, because left cushion blocking device 32 is opened, so seat cushion 21 can further rotate towards body tail around left side bolster 28a shown in arrow m.At this moment, control setup 36 detects the motor current of driving motor 55 and determines whether detected value is higher than threshold values.

For example, interfere and motor current when surpassing threshold values, driving motor 55 is stopped at seat cushion 21 and obstacle (not shown).

When seat cushion 21 is not interfered with obstacle, owing to motor current value does not increase above threshold values, so seat cushion 21 shown in arrow m further towards the posterior rotation of vehicle body.

Herein, because control setup 36 is installed in the seat cushion 21, so in first to fourth electric wiring 58,64,68 and 73 (referring to Fig. 3) can be packed into seat cushion 21 and the back of seat 22,23.Therefore, when seat cushion 21 was rotated, first to fourth electric wiring 58,64,68 and 73 can not blocked by seat cushion 21.

With reference to Figure 20 A and Figure 20 B the operation of ST05 shown in Figure 11 is described below.

Shown in Figure 20 A, when seat cushion 21 towards the posterior rotation of vehicle body and when being incorporated in the floor recess 16, the rear surface 24a of left headrest 24 is resisted against on the upper end 18a of rear wall 18 of floor recess 16.Because predetermined load F acts on the rear surface 24a of left headrest 24, shown in arrow r, fold left headrest 24 around pivot 85 like that so overcome the elastic force ground of coil spring 87 (referring to Fig. 4).In this state, seat cushion 21 shown in arrow m towards the posterior rotation of vehicle body.

Shown in Figure 20 B, seat cushion 21 is resisted against on the bottom surface 19 of floor recess 16.The motor current value of driving motor 55 (referring to Fig. 3) increases above threshold values, so driving motor 55 stops.As a result, seat cushion 21 and left seat back 22 (second back seat 15) are accommodated in the floor recess 16, and the process of taking in finish.

In this way with seat cushion 21 and left seat back 22 (second back seat 15) when being accommodated in the floor recess 16, owing to needn't take off left headrest 24 from left seat back 22, so can be without any easily second back seat 15 being accommodated in the floor recess 16 troublesomely.

Equally, as shown in Figure 20 A, be resisted against by the rear surface 24a that makes left headrest 24 on the upper end 18a of the rear wall 18 that forms floor recess 16, left headrest 24 rotated around pivot 85 shown in arrow r like that, and overcome coil spring 87 (referring to Fig. 4) elastic force fold.Owing to members such as axle that must need not to add the pivot 91 (referring to Fig. 3) that departs from left seat back 22 and electric wires, so can simplified structure.
