＜connecting rod and coupled switch 〉
As shown in Figure 5, hinge is in conjunction with on 31 the shell 45, is provided with the hinge of the concentric action component of the centre of gration of the chair back 4 and combines crank 46 and above-mentioned coupled switch 42.Coupled switch 42 is connected the conversion of cut-out for directly accepting hinge in conjunction with the action of crank 46, is provided with in conjunction with crank 46 near this hinge.
Below, specifically describe.Fig. 6 and Fig. 7 represented hinge in conjunction with 31 and coupled switch 42 between relation.Still, among Fig. 6 and Fig. 7 just modal representation hinge in conjunction with crank 46.Hinge comprises in conjunction with 31: on the chair back 4 with the concentric pair of locking parts (second bonded block) 52 that fixing inner gear (first bonded block) 51 are set, are arranged on the inboard of this inboard gear 51 of its centre of gration, drive the protruding part 53 of Lock Part 52.On this protruding part 53 in conjunction with hinge in conjunction with crank 46, constitute in conjunction with the action component of removing structure in conjunction with crank 46 and protruding part 53 by this hinge.
Inner gear 51 is included in and clips a pair of internal tooth 54 that its axle center (identical with the centre of gration of the chair back 4) forms relatively on the inside face of annular element.Formed (protuberance that internal diameter little) crowning 55 higher between two internal tooths 54 of this inner gear 51 than increment face.
Pair of locking parts 52 are arranged on the position that clips above-mentioned axle center, have formed the locking teeth 56 that combines (engagement) with internal tooth 54 on the face outwardly.These two Lock Parts 52, but the diametric(al) that is supported on car body one side and large internal gear 51 moves freely (or chair cushion one side.Below, " car body one side " also can mean " chair cushion one side "), and with releasing direction that internal tooth 54 combines on, just by the resilience device (omit diagram) of resilience to axle center one side shifting.Be engaged in the internal tooth 54 of inner gear 51 by this Lock Part 52, the chair back 4 is supported for respect to fixed erected state of car body one side mark or the preceding lock-out state that falls state.Just, the lean forward screen resilience of lodging resilience device (coil spring) of the chair back 4 opposing is supported for and holds up or state is fallen in the back.Removed the combination of Lock Part 52, the chair back 4 is with respect to car body one sideway swivel freedom, and its result is dumped forward by the screen resilience of the lodging resilience device that leans forward.
Protruding part 53 is arranged between the pair of locking parts 52, can rotate freely on every side in above-mentioned axle center.On the surface of this protruding part 53, clip above-mentioned axle center and relative pair of engaging face 57 and clip a pair of releasing face 58 in above-mentioned axle center equally, adjacent setting on Zhou Fangxiang.As shown in Figure 6, rotation protruding part 53 and pair of engaging face 57 are when the face of the inboard of two Lock Parts 52 (axle center one side) contact (first form), and this two Lock Part 52 resists the mobile laterally chair back lock-out state that combines with internal tooth 54 that becomes of above-mentioned resilience.On the other hand, a pair of releasing face 58 is than the more close above-mentioned axle center of face of joint 57.Therefore, protruding part 53 rotation, as shown in Figure 7, the medial surface (axle center one side) of two releasing faces 58 and two Lock Parts 52 is when face contact (second form), and two Lock Parts 52 become disarm state by the mobile to the inside releasing internal tooth 54 of above-mentioned resilience in conjunction with the chair back.
Hinge is in conjunction with crank 46 and protruding part 53, in conjunction with internal tooth 54 chair back 4 is supported on first form (with reference to Fig. 6) of car body one side for becoming face of joint 57 contact Lock Parts 52 Lock Parts 52, and its hand of rotation is by 59 resiliences of resilience device.Therefore, hinge is drawn by first hauling rope 47 by operating knob 7 in conjunction with crank 46, and as shown in Figure 7, protruding part 53 rotation releasing faces 58 become second form (chair back disarm state) to the medial surface contact of Lock Part 52.
In the present embodiment, constitute in conjunction with removing structure in conjunction with crank 46, protruding part 53 and resilience device 59 by above-mentioned operating knob 7, transferring elements 34, first hauling rope 47, hinge.
And, coupled switch 42, as shown in Figure 6, when above-mentioned first form (chair back lock-out state), be set to hinge becomes dissengaged positions in conjunction with crank 46 contacts to hinge in conjunction with crank 46.As shown in Figure 7, hinge moves to chair back releasing position in conjunction with crank 46 and leaves coupled switch 42 (second form), and this coupled switch 42 becomes on-state.
Represented the state that the chair back 4 is holded up with solid line among Fig. 8, represented preceding state with long and two-short dash line.In above-mentioned regulation erected state, coupled switch 42 becomes dissengaged positions by hinge in conjunction with the contact of crank 46.After hinge was drawn by operating knob 7 in conjunction with crank 46, when Lock Part 52 became chair back disarm state, hinge left coupled switch 42 in conjunction with crank 46, and this coupled switch 42 becomes on-state.
This state long and two-short dash line in Fig. 8 is represented, the chair back 4 is because the screen resilience of the lodging resilience device (spring) that leans forward when dumping forward, inner gear 51 rotates in the direction of arrow A with the chair back 4 as shown in Figure 7, and Lock Part 52 becomes the state of the crowning 55 of contact inner gear 51.This state is to stop Lock Part 52 to make the resilience of protruding part 53 opposing resilience devices 59 return the state of chair back lock-out state.Therefore, even if remove traction by operating knob 7, coupled switch 42 also keeps on-state.
In this embodiment, when the chair back 4 was holded up erected state into regulation, the locking teeth 56 of Lock Part 52 meshed for making in the position of adjacency crowning 55 relatively for the internal tooth 54 of inner gear 51, has set the position relation of inner gear 51 and Lock Part 52.Have again, in above-mentioned chair back disarm state, even if the preceding fully state that before this chair back 4, overlaps with chair cushion 3, the locking teeth 56 of Lock Part 52 is for crowning 55, for not making and internal tooth 54 engagements, even if fall state before the chair back 4 becomes fully, coupled switch 42 is also keeping on-state (allowing the state to electro-motor 33 energisings).
Therefore, making operation switch 8, electro-motor 33 start the chair back 4 and hold up gradually.And the chair back 4 reaches the erected state of regulation, the internal tooth 54 of the locking teeth 56 engagement inner geares 51 of Lock Part 52, when supporting the erected state of the chair back 4 for regulation, coupled switch 42 becomes dissengaged positions, cuts off the energising of electro-motor 33 and it is stopped, and just no longer produces moment of torsion.
Also have, shown in the long and short dash line among Fig. 9, the chair back 4 is when the erected state of regulation, and draw operations button 7 becomes chair back disarm state, by the chair back 4 is overcome refund ereisma before above-mentioned screen resilience to pusher, can shown in solid line, swing to the rear.And, remove the traction of operating knob 7, protruding part 53 is because the screen resilience of resilience device 59 rotates, and by the internal tooth 54 of Lock Part 52 engagement inner geares 51, the chair back 4 is supported for the state of toppling over proper angle backward.The internal tooth 54 of inner gear 51 for making the chair back 4 from the erected state of the regulation back state that falls of level of approximation rearward, can also be supported for suitable angle, has set the specialized range of inner gear circumferencial direction.Also have, the chair back 4 is rearward toppled over the state that suitable angle supports by Lock Part 52, hinge is contacted the state (the solid line state of Fig. 9) of coupled switch 42 by the screen resilience rotation of resilience device 59 in conjunction with crank 46.Therefore, because coupled switch 42 is in dissengaged positions, so even if making operation switch 8 electro-motors 33 can not start yet.
The chair back of＜electro-motor is holded up mechanism 〉
As shown in figure 10, fixed motor support parts 61 on the seat back frame 25 of back seat 2, these motor support parts 61 upper supports electro-motor 33.Also have, on these motor support parts 61, driven wheel 62 is supported for the axle center in the overall width direction rotatably by the output shaft of electro-motor 33.As shown in figure 11, driven wheel 62 is to be rotated ground by the worm screw on the output shaft that is combined in electro-motor 33 63.Still, electro-motor 33 and worm screw 63 are called electro-motor altogether, still, among the present invention, comprise that also driven wheel 62 is not by worm screw and situation about only being driven by electro-motor 33.On the other hand, be fixed on the angle brace 64 on the hull bottom plate, supporting concentric and rotate ring gear 65 freely with the centre of gration of the chair back 4 of back seat 2.Meshing driven wheel 62 on this ring gear 65.
On the ring gear 65, be wholely set combination gear 66 with 65 rotations of this ring gear.On the other hand, support on the pivot shaft 68 of overall width direction of angle brace 64 rotation freely supporting may with combination gear 66 ingear universal joint parts 67.But, this universal joint part 67, by resilience device (spring) 69 for towards in conjunction with the direction of combination gear 66 rotation resilience.Also have, on the motor support parts 61, freely supporting releasing crank 71 by pivot shaft 71 rotations of overall width direction.Removing crank 71, is the combination of the screen resilience releasing of the above-mentioned resilience device 69 of opposing to the combination gear 66 of universal joint part 67.In this case, combination gear 66 and universal joint part 67, constitute to stop ring gear 65 with the chair back 4 rotations in conjunction with disconnector.
On the combination gear 66, according to the rules the interval in a circumferential direction that has formed tip Hooke's coupling 73 combinations of universal joint part 67 has formed a plurality of in conjunction with tooth 74.In conjunction with the flank of tooth (face of joint) of tooth 74, the place ahead of the axle center that is parallel to ring gear 65 hand of rotation when the chair back dumps forward, and launch in the approximate diameter direction of ring gear 65.Also have, this is provided with at interval in conjunction with tooth 74, is set at than the chair back 4 from the erected state of afore mentioned rules 120 bigger a little degree of chamfer angle (100～115 degree) before fall before fully till the state rotatably forward.Therefore, be provided with three in conjunction with tooth 74 in the present embodiment.Still, also promptly can be one or two in conjunction with tooth 74.
Therefore, the Hooke's coupling 73 of universal joint part 67 and combination gear 66 combine tooth 74 combinations, ring gear 65 just can't the rotation of falling the direction before the chair back.Therefore, the chair back 4 is in preceding when falling the state, make universal joint part 67 be in above-mentioned bonding state and start electro-motor 33, make driven wheel 62 hold up the direction rotation, stoped rotation to accept the rotation counter-force of driven wheel 62 by ring gear 65 by universal joint part 67 to the chair back.Thus, driven wheel 62 makes ring gear 65 while rotating rotation is moved towards the direction of chair back rotation, just, by the change of the engage position of driven wheel 62 and ring gear 65, holds up the chair back 4.Just, the moment of torsion of electro-motor 33 is passed to car body one side by driven wheel 62 and ring gear 65, and the chair back is holded up.
In the present embodiment, electro-motor 33, setting the chair back 4 is fallen the desired time of erected state that state holds up afore mentioned rules before fully is (best is three to four seconds) below seven seconds.Also have, refund ereisma before above-mentioned, the chair back 4 is fallen before fully time of state from the erected state of afore mentioned rules, the ratio of setting falls state before fully with the chair back 4, and to hold up desired time of erected state of afore mentioned rules short.Thus, guarantee safe in, shortened the shifting time that falls between state and the erected state before fully and improved comfort feature.
＜transmission remover 〉
On the universal joint part 67, be provided with as the pin of accepting from the receiving portion of the releasing power of removing crank 71 76.On the other hand, remove on the crank 71, be provided with from the pin contacts portion 77 of existence in conjunction with combination gear 66 1 side contacts of the pin 76 of universal joint part 67.Removing crank 71, is to make pin contacts portion 77 to the direction rotation away from pin 76 by resilience device (spring) 78 resiliences.And this is removed on the crank 71, in conjunction with extending second hauling rope 79 that links operating knob 7 by the transferring elements of narrating previously 34.Just, the tractive force of operating knob 7 is passed to by second hauling rope 79 and is removed crank 71, and this releasing crank 71 is being resisted the screen resilience rotation universal joint part 67 of resilience device 78, that is, and and to the direction rotation of removing the combination of combination gear 66.This situation, operating knob 7, transferring elements 34, second hauling rope 79, releasing crank 71 and resilience device 78 constitute the transmission remover that is not become resistance by rotation stopping electro-motor of falling when 33 before the chair back of removing ring gear 65 in conjunction with disconnector.
Be under the state of shaking for universal joint part 67 is left from combination gear 66 at releasing crank 71, the chair back 4 begins to dump forward from the erected state of regulation, at this moment, removing the rotation that crank 71 is accompanied by the chair back 4 moves to the direction away from universal joint part 67.Therefore, the pin contacts portion 77 that removes crank 71 frees from the pin 76 of universal joint part 67, and universal joint part 67 returns the direction that combines with combination gear 66.
Also have, adjacent on the circumferencial direction of combination gear 66 in conjunction with having formed crowning 81 between the tooth 74.This crowning 81 is in the chair back 4 dumps forward the way, the resilience by above-mentioned resilience device 69 with removed the object that contacts with first end in conjunction with the Hooke's coupling 73 of the universal joint part 67 of the combination of tooth 74.This crowning 81 by the restoring force of the above-mentioned resilience device 69 of Hooke's coupling 73 acceptance, is to impel combination gear 66 with the object of ring gear 65 to the lodging direction rotation of leaning forward of the chair back.
For this reason, crowning 81, from each the flank of tooth tip position of axle center (away from) in conjunction with tooth 74, the flank of tooth cardinal extremity in conjunction with tooth 74 on the hand of rotation rear side next door when before the chair back, the falling position of axle center (near), radius shortens (inclination) gradually.And universal joint part 67, the restoring force that is configured such that above-mentioned resilience device 69 apply with the direction that becomes acute angle on one side of above-mentioned hand of rotation the place ahead with respect to above-mentioned crowning 81.
Therefore, as shown in figure 11, when the chair back 4 is in the erected state of regulation, universal joint part 67 be combined in combination gear 66 in conjunction with on the tooth 74.Draw operations button 7 as shown in figure 12, is removed crank 71 to removing the direction rotation, follows in this, and universal joint part 67 is to removing direction rotation breaking away from conjunction with tooth 74 from combination gear 66.Thus, ring gear 65 has been disengaged by the constraint of universal joint part 67 to car body one side, and the chair back 4 of refunding the helical spring screen resilience of ereisma before accepting can the rotation of falling the direction before the chair back.
Therefore, when the chair back 4 dumped forward, ring gear 65 was with dump forward direction rotation of the chair back 4.At this moment, the engage position of driven wheel 62 and ring gear 65 is relative constant, and this just means, the reversing sense rotation when there is no need to make the output shaft of the electro-motor 33 by driven wheel 62 and the chair back to hold up., just can prevent when electro-motor 33 from being rotated by external force and the contrary moment of torsion that produces, or because the rotational resistance of the reductor class of the engagement of the engagement of driven wheel 62 and ring gear 65, driven wheel 62 and worm screw 63 etc. becomes the lean forward resistance of lodging of the chair back for this reason.
Also have, after the chair back 4 began to lean forward, releasing crank 71 was accompanied by the rotation of the chair back 4 and moves towards the direction away from universal joint part 67.Thus, as shown in figure 13, the pin contacts portion 77 that removes crank 71 frees from the pin 76 of universal joint part 67, and its Hooke's coupling 73 of universal joint part 67 touches on the crowning 81 of combination gear 66 by the resilience of resilience device 69.Its result, ring gear 65 is the direction rotation of leaning forward towards the chair back by 69 resiliences of resilience device.For this reason, ring gear 65 just really with the chair back 4 towards the chair back direction rotation of leaning forward.
As shown in figure 14, fall before the chair back 4 becomes fully behind the state, universal joint part 67 just be in can with the adjacent or next state that combines tooth 74 combinations of this crowning 81 of combination gear 66.Therefore, start electro-motor 33, driven wheel 62 just rotates ring gear 65, and the chair back 4 is holded up.Still, by being set at 120 above-mentioned degree in conjunction with the spacing that is provided with of tooth 74, under the situation that electro-motor 33 is not rotated fully, in when falling the state before the chair back 4 becomes fully, the tip of universal joint part 67 just is in adjacent in conjunction with tooth 74 fwd positions in falling before the chair back 4.Therefore, during from the startup of electro-motor 33, to starting universal joint part 67 and the adjacent tooth 74 that combines by this in conjunction with till beginning to hold up the action of the chair back 4, the time lag shortening, it is favourable that the chair back 4 is holded up fast.
The operation of＜back seat 〉
Action with above the same each several part when coming description operation back seat 2.
Preceding the fall of-chair back-
When the chair back 4 was in the erected state of regulation, hinge was in conjunction with 31, as shown in Figure 6, was in the state that hinge is rotated down by the resilience of resilience device 59 in conjunction with crank 46.For this reason, the crowning 52 of protruding part 53 contacts with Lock Part 52, and this Lock Part 52 combines with the internal tooth 54 of inner gear 51.Thus, the chair back 4 is supported for this erected state.Also have, hinge is in conjunction with crank 46 contact coupled switchs 42 (the solid line state of Fig. 9), and coupled switch 42 becomes dissengaged positions.Therefore, even if making operation switch 8 can not start electro-motor 33 yet.On the other hand, by holding up in the portion of mechanism of electro-motor 33, as shown in figure 11, universal joint part 67 be combined in combination gear 66 in conjunction with on the tooth 74.
In described erected state, draw operations button 7, hinge is rotated up with protruding part 53 by 47 tractions of first hauling rope in conjunction with crank 46 in conjunction with hinge in 31, thus, removes the support (with reference to Fig. 7) of the chair back 4 by Lock Part 52.Just, the chair back 4 just becomes by the resilience of preceding refunding ereisma and can dump forward.On the other hand, hold up and remove crank 71 in the portion of mechanism by 79 tractions of second hauling rope, thus, the Hooke's coupling 73 of universal joint part 67 is freed in conjunction with tooth 74 from combination gear 66, and ring gear 65 just can rotate freely (with reference to Figure 12) with respect to car body.
Therefore, when the chair back 4 dumped forward by the resilience of preceding refunding ereisma, ring gear 65 was with the chair back 4 rotations of falling the direction before the chair back.Therefore, in fact there is no need the driven wheel 62 of rotary electric motor 33, avoided electro-motor 33 to become the preceding resistance of the chair back 4.Just, as present embodiment, combine worm screw 63 on the output shaft of electro-motor 33, mesh driving gear 62 on this worm screw 63, worm screw 63 just becomes the rotational resistance of driven wheel 62.But, such as mentioned above, owing to there is no need to reverse driven wheel 62 (can on driven wheel 62, act on) when the chair back 4 dumped forward against moment of torsion, so, avoided worm screw 63, the resistance when just electro-motor 33 becomes the chair back and dumps forward.Therefore, when the chair back 4 dumps forward, do not need to apply big external force, only just can be soon and the chair back 4 that positively dumps forward by the resilience of preceding refunding ereisma, chaufeur need not fall colored too big strength during the chair back 4 preceding.
The chair back 4 is when the erected state of afore mentioned rules begins to dump forward, as shown in figure 13, leave universal joint part 67 by removing crank 71, the Hooke's coupling 73 of this universal joint part 67 is pulled on the crowning 81 of combination gear 66 by the resilience of resilience device 69.Thus, on combination gear 66, be applied in the power of the rotation of falling the direction before the chair back that provides by resilience device 69, promoted ring gear 65 rotation of direction before the chair back.So, avoided on driven wheel 62, producing backward rotational force, just avoided electro-motor 33 to become the resistance that falls before the chair back.After the chair back 4 lodged on the chair cushion 3 fully, as shown in figure 14, universal joint part 67 became the adjacent state in conjunction with tooth 74 of this crowning 81 of engagement gear 66.
Still, even if removed the traction of operating knob 7 before breaking away from universal joint parts 67 removing crank 71, universal joint part 67 is in case from the breaking away from conjunction with tooth 74 of combination gear 66, because the preceding of the chair back 4 falls, universal joint part 67 just contacts with crowning 81.
On the other hand, hinge is in conjunction with in 31 1 sides, because the preceding of the chair back 4 begin, as shown in Figure 7, because inner gear 51 is with the chair back 4 rotations, so Lock Part 52 just becomes the state of the crowning 55 of contact inner gear 51.Lock Part 52 is contacting crowning 55 chair back 4 becomes above-mentioned preceding fully state.Therefore, even if remove the traction of operating knob 7 in the preceding way of the chair back 4, the chair back 4 is also owing to refund before above-mentioned to fall before ereisma continues.Also have, the contact of the crowning 55 by Lock Part 52, hinge breaks away from from coupled switch 42 in conjunction with crank 46, coupled switch 42 becomes on-state (words of making operation switch 8 just allow the state to electro-motor 33 energisings), even if remove the traction of operating knob 7, also can keep this on-state.
Still, removed the traction of operating knob 7 after because the crowning 55 of the locking teeth 56 of Lock Part 52 contact inner geares 51, so hinge does not return fully in conjunction with crank 46, for this reason, relaxing just can appear in first hauling rope 47.
Fall by the preceding of the chair back 4, chair cushion 3 is pushed away forward by the chair back 4, and as shown in Figure 2, the chair cushions 3 that fall before the connecting rod 13 reduce height, the folding in the above chair back 4.Thus, loading railway carriage or compartment 5 enlarges to compartment one side, also can place object on the back side of the chair back 4.
The holding up of-chair back-
The chair back 4 fully before under the state of chair cushion 3, as mentioned above,, pin the operating switch 8 in loading railway carriage or compartment 5 because coupled switch 42 becomes on-state, be activated (with reference to Fig. 4) by energising electro-motor 33 from battery.On the other hand, as shown in figure 14, fall before fully in the state, universal joint part 67 be attached to combination gear 66 in conjunction with on the tooth 74, ring gear 65 becomes and has been prevented from falling the state of rotation of direction to the chair back preceding.
Therefore, by the startup of electro-motor 33, driven wheel 62 rotations, its rotation counter-force is accepted by ring gear 65, and driven wheel 62 rotates the tooth portion of ring gear 65.Just, the chair back 4 is holded up gradually.In the holding up of this chair back 4, as shown in Figure 4, contacting the state of the crowning 55 of inner gear 51 because be hinge in conjunction with 31 Lock Part 52, so coupled switch 42 keeps connecting.Therefore, as long as pin operating switch 8, just can keep the connection of electro-motor 33.
When the chair back 4 was in erected state shown in Figure 11, as shown in Figure 6, the internal tooth 54 of inner gear 51 was just relative with Lock Part 52.Thus, Lock Part 52 is engaged in internal tooth 54, and the chair back 4 is supported for this erected state.Simultaneously, hinge is rotated down contact coupled switch 42 in conjunction with crank 46 by the resilience of resilience device 59, and this coupled switch 42 becomes on-state.For this reason, operating switch 8 be exactly be in by by state, cut off by coupled switch 42 to the energising of electro-motor 33, this electro-motor 33 is in the state that does not produce moment of torsion.
As, by continuing to pin operating switch 8, can make the chair back 4 hold up the regulation erected state till.And the chair back 4 arrives the erected state of regulation, even if continue to pin operating switch 8, the action of electro-motor 33 also can stop, and the chair back 4 is supported for this erected state really.Therefore, chaufeur falls state when holding up with the chair back 4 in the past, the loading railway carriage or compartment 5 operating operation switches 8 from leaving back seat 2 do not need while the situation of the holding up operating operation switch 8 of confirming the chair back 4, even if can be holded up the chair back 4 erected state of stipulating really yet.Just, can avoid the chair back 4 to become or too rearward fall down and make and take discomfort, also have, also avoid the goods placement space at back of the chair back too narrow than the predetermined state of more holding up.
Also have, because electro-motor 33 no longer produces moment of torsion, thus just avoided on the chair back 4, or hinge is favourable in conjunction with 31 first-class effect overloads to the durability that improves back seat 2.
Also have, because operating switch 8 is automatic restoring type switches, so, in holding up on the way, the chair back 4 stops to press operating switch 8, just interrupted stopping to hold up to the energising chair back 4 of electro-motor 33.Therefore, hold up in the way of the chair back 4 by electro-motor 33 again, soon knock the chair back 4 when sandwiching object between this chair back 4 and the car body sidewall or on the object in loading railway carriage or compartment 5 and when object is damaged,, make the chair back 4 stop at the generation of avoiding accident midway as long as hand leaves from operating switch 8.
Hold up in the way when stopping electro-motor 33 at the chair back 4, universal joint part 67 be attached to combination gear 66 in conjunction with on the tooth 74, stop ring gear 65 before the chair back, to fall the rotation of direction.Therefore, refund the screen resilience of ereisma before the chair back 4 is accepted, and electro-motor 33 becomes resistance and fall before can be at once.Also have, after the holding up of the chair back 4 stopped electro-motor 33 in the way, the making operation switch 8 once more, and the chair back 4 continues to be holded up the erected state of regulation, and the state lower support that electro-motor 33 is stopped is this erected state.
Also have, draw operations button 7 makes the chair back 4 situation of making operation switch 8 way before erected state, and the chair back 4 turns back to the erected state of regulation.In the preceding way of the chair back 4, coupled switch 42 is in on-state as previously mentioned, making operation switch 8, and electro-motor 33 has just been led to.But, as shown in figure 13, in preceding way, even if because electro-motor 33 rotation driven wheels 62, the chair back 4 can be at once to holding up the direction rotation yet.Rotation by driven wheel 62, ring gear 65 is with preceding the fall direction rotation of combination gear 66 to the chair back, from combination gear 66 in conjunction with tooth 74 be combined in universal joint part 67 stop fall before the chair back of these ring gears 65 direction rotation that, the chair back 4 begins to hold up.
Back the fall of-chair back-
The chair back 4 is when the erected state of regulation, and coupled switch 42 is in on-state as mentioned above.From this state, for the chair back 4 is shifted onto backward, draw operations button 7 by hinge in conjunction with 31 centres of removing the support of the chair back 4, maloperation operating switch 8 make its connection, but owing to operating knob 7 is pulled coupled switch 42 can't be connected, electro-motor 33 is energized and rotates.But so-called operating knob 7 is pulled, and the combination of universal joint part 67 and combination gear 66 just has been disengaged, so, even if electro-motor 33 actions can be to chair back transfer torque yet.Just, the chair back 4 can not toppled over backward by electro-motor 33, has improved safety.
Topple over backward in the chair back 4, draw operations button 7 overcomes the chair back 4 by the power of before refunding the resilience of ereisma and dumping forward, and the chair back 4 is pushed over backward.For example chaufeur is in the state of taking and gets final product by afterwards promoting the chair back 4 thereafter dorsad.And, when the chair back 4 arrives suitable back chamfer angle, remove the traction of operating knob 7, hinge is attached on the internal tooth 54 of inner gear 51 in conjunction with 31 Lock Part 52, and the chair back 4 is supported on this back chamfer angle.
In the state of draw operations button 7, as shown in figure 12, universal joint part 67 leaves combination gear 66, so ring gear 65 is not subjected to the resistance of universal joint part 67, the chair back rotates backward becomes possibility.Therefore, ring gear 65 keeps the engage position identical with driven wheel 62, rotates backward with the chair back 4, and electro-motor 33 can not become the back resistance of the chair back.
Also have, remove crank 71, be under the erected state at the chair back 4, for becoming the posture that makes pin 76 contacts, limit its posture by second hauling rope 79, the moment of torsion that constitutes electro-motor 33 transmits killer.Just, arrive backward by the chair back 4, this chair back 4 inclination backward is big more, removes crank 71 whole tilted rearward and moves, and follows in this, and universal joint part 67 recedes and removes the combination in conjunction with tooth 74 of this universal joint part 67 and combination gear 66.Therefore, even if drive electro-motor 33, combination gear 66 is with ring gear 65 idle running, prevented that the back of the chair back 4 from falling.
By such function, for example, when chaufeur is taken on the seat, even if contacted operating switch 8 carelessly, under chaufeur is drawing situation for operating knob 7 that the chair back 4 is toppled over backward, or the aging combination that can't remove universal joint part 67 and combination gear 66 such as second hauling rope, as long as the back degree of falling of the chair back 4 (is seen more than the defined degree from the side, the chair back 4 and horizon angulation are below predetermined angular), the chair back 4 can not fall backward again.Perhaps, at the firm draw operations button 7 of chaufeur, owing to above-described reason begins unusual toppling over backward, even if like this, thereafter as long as the chair back 4 back proceeds to the back to fall more than the prescribed limit, the chair back 4 just not again the back fall.Thus, the object breakage in the loading railway carriage or compartment or give by bus that personnel bring discomfort can obtain relaxing.Still, the angle of afore mentioned rules, according to the shape of removing crank or the position is set can changes to some extent, recede a little as a erected state only from the chair back 4, limit the inclination more than this.Just, it also is possible limiting the back of electro-motor 33 in fact.
Also have, the chair back 4 is in the back and falls under the state, and draw operations button 7 is removed the support of hinges in conjunction with 31 the chair back 4, and the chair back 4 is by the resilience of preceding refunding ereisma, and the state that falls from the back is holded up.Also be to break away from from combination gear 66 in this case, be not subjected to the resistance of electro-motor 33, can hold up the chair back 4 by removing crank 71 universal joint parts 67.And, when the chair back 4 is holded up the angle of hope, remove the traction of operating knob 7, hinge is attached to the internal tooth 54 of inner gear 51 in conjunction with 31 Lock Part 52, and the chair back 4 is supported for this angle.Also have, if continue the traction state of operating knob 7, hinge is in the state that supports of removing in conjunction with 31, and the chair back 4 continues to dump forward from above-mentioned back tilt state.
Still, be not provided with in the vehicle of above-mentioned back seat 2, also can at the structure that is equivalent to be suitable on the seat of row's seat 1 in above-mentioned present embodiment.
The present invention, the embodiment by example is not limited, and under the situation that does not exceed main idea of the present invention, need not say that the change in all improvement and the design is possible.
