More specifically, release lever 38 is arranged on the below of seat cushion 2 leading sections rotationally.That is to say that release lever 38 is fixed on the pivot shaft 37A, pivot shaft 37A is being connected rotationally with the preceding square tube type frame member 12 of seat cushion frame 2A, thereby can rotate between inoperative lockup state shown in Figure 2 and released state shown in Figure 4.One tractive spring 39 is connected between a release lever 38 and the clamp structure (not shown), this clamp structure is fixed on the inboard of seat cushion frame 2A side frame section 20L, thereby release lever 38 is setovered to lockup state by this spring 38 under normal conditions.
Label 37 refers to a connector, and it is disposed in the place ahead of seat framework 2A, and in the position near release lever 38, the upper end of this connector 37 is fixed on the above-mentioned pivot shaft 37A.
First pivot arm 32 is disposed in after the seat framework 2A, and is shaped on an adapter shaft 33 on it, is shaped on a tapped bore 33A in the adapter shaft 33.
First connecting rod 31 movably is connected between these connectors 37 and first pivot arm 32 according to certain way, so that the lower end of the front end of first connecting rod by a pin rod 31A and connector 37 couples together pivotly, its rear end then couples together pivotly by the lower end of the pin rod 31B and first pivot arm 32.
Can be clear that from Fig. 3, the adapter shaft 33 of first pivot arm 32 is inserted in the hole 20 rotationally, this hole is on the position, rear end of side frame section 20L, and the present position is close to bearing pin 21, and bearing pin 21 is gone up specific back-end region level from side frame section 20L and stretched out.
Also can be clear that from Fig. 3, be shaped on the bullport 10 and a support holes 11 of an arc on the upper area of base frame spare 1, and make bullport 10 along a round circumferential extension, this circle is the center of circle with support holes 11.Bearing pin 21 is inserted in the described support holes 11 on the base frame spare 1 rotationally, make seat cushion frame 2A can turn to base frame spare 1 in vertical direction thus or leave base frame spare, thereby seat cushion 2 upwards can be dug setting non-working condition shown in Figure 5.On the other hand, the adapter shaft 33 of first pivot arm 32 interted the bullport 10 of arc slidably.Thereby as can be seen: when bearing pin 21 rotated, adapter shaft 33 can slide along the bullport 10 of arc at seat cushion frame 2A.
The adapter shaft 33 that interted arc bullport 10 like that as indicated above is connecting regularly with the upper end of second pivot arm 34.As shown in Figure 3, by a tightening screw 33B is passed one on second pivot arm, 34 upper ends hole 34A and be screwed among the tapped bore 33A of adapter shaft 33, just the adapter shaft and second pivot arm 34 can be linked up regularly.One end of second connecting rod 35 pivots with the lower end of second pivot arm 34 by a pin rod 35A and is connected.The other end of second connecting rod 35 keeps pivoting with an end regions of rotary actuator block 36 and is connected, and this end regions on the actuator block 36 is facing to the place ahead of seat S.
Have a pressure rod 36B for rotary-actuated 36, it extends back to lockable mechanism LM, and its front end is being connected with the lower end of base frame spare 1 rotationally by a pin rod 36A, thereby can rotate around pin rod 36A.Rotary-actuated 36 front end is being connected pivotly with the lower end of second connecting rod 35, and thus, second connecting rod 35 is connected between pivot arm 34 and rotary-actuated 36 pivotly.
In this article, as can be seen from Figure 2, when seat S is in normal operating condition shown in the solid line, release lever 38 is in lock position, thereby locking/release actuating mechanism 3 or its all constituent elementss (31,32,33,34,36,37 etc. above-mentioned each parts) all are in off working state with respect to lockable mechanism LM, under this state, be maintained at for rotary-actuated 36 in the graphic off working state, at this moment, pressure rod 36B extends back along the straight line on even keel.
The centre portion of pitching actuated piece 41 is pivotally connected to the position, upper end of rail 4B by a pin rod 41A, and with last rail 4B horizontal-extending abreast, half part 41-1 of this actuated piece extends back and crosses latch plate 42, and keep pivot to be connected with latch plate 42 by a pin rod 42B, second half part 41-2 of actuated piece extends forward, and 36B is parallel with pressure rod, but its height of living in is lower than pressure rod 36B.
Below, with concrete with reference to Fig. 2,4 and Fig. 5 the working process of seat S with said structure is described.
At first, expression in conjunction with Fig. 3, can be as can be seen from Figure 2, overcoming the bias force of spring 39, by the direction shown in the arrow A 1 with locking rod 38 forward (or widdershins) turn to a unlocked position, this can make connector 37 rotate in the counterclockwise direction simultaneously conversely, and first connecting rod 31 is moved on direction A2 forward.Meanwhile, first pivot arm 32 is seat cushion in the counterclockwise direction also, impels adapter shaft 33 also to produce similarly and rotates, and second pivot arm 34 is rotated around adapter shaft 33 along the anticlockwise direction shown in the arrow A 3.Utilize the rotation of second pivot arm 34, second connecting rod 35 moves up along direction shown in the arrow A 4, make rotary-actuated 36 thus around pin rod 36A, on the direction shown in the arrow A 5, rotate counterclockwise, thereby pressure rod 36B is contacted with second half part 41-2 of pitching actuated piece 41, and be directed downwards rotation shown in arrow A 6, and then double part 41-2 exerts pressure.As the result of this a series of actions, pitching actuated piece 41 clockwise rotates along direction shown in the arrow A 7 around pin rod 41A, thereby makes latch plate 42 be moved upwards up to a unlocked position, so just three lock banking stop 42A and cooresponding three locking holes 43 can be separated from.These a series of unlocking operations in Fig. 4, have also been expressed, can find out from this accompanying drawing: 1. the locking motion that the unlocking operation of release lever 38 and rotary-actuated 36, pressure rod 36B and pitching actuated piece 41 meanwhile produce is all represented by arrow, and 1. latch plate 42 is also referred to by arrow from the motion that rail 4A down upwards throws off.The result of this operation is: go up rail 4B and free from the state that is locked into down rail 4A, allow seat S mobile before and after on the direction shown in the arrow in Fig. 4 thus.
Therefore, the user can move to desirable location point place with seat S by such operation: the bias force that is overcoming spring 39, with hand release lever 38 is remained on released state shown in Figure 4, then, can as the arrow among Fig. 2 2. shown in, release lever 38 is discharged, make it be in Immobile lockup state, make rotary-actuated 36 thus and clockwise rotate on the direction shown in 2. at arrow, and then three lock banking stop 42A of latch plate 42 are joined in three selected locking holes 43 by means of pitching actuated piece 41, thereby seat S just is locked in down the ideal position point place on the rail 4A.Should be noted that: under this lockup state, under the bias force effect of spring 39, latch plate 42 is forcibly held on following rail 4A.
Afterwards, the user can dig seat cushion 2 setting non-working condition shown in Figure 5.As can be seen from Figure, at this moment, because seat cushion 2 upwards rotates or digs, adapter shaft 33 is since an initial position, trackslip with respect to bolster 21 conter clockwises along the bullport 10 of arc, wherein, on reference position, seat cushion 2 is in the running condition of basic horizontal, and adapter shaft 33 contacts with the upper end or the upper limb of arc bullport 10.That is to say that when seat cushion 2 was dug, adapter shaft 33 moved to lower edge from the upper limb of arc bullport 10.This has just reserved degree of freedom for adapter shaft 33 around the rotation of bolster 21, thereby can prevent that adapter shaft 33 from influencing the action of digging of seat cushion 2, and, in addition, what should also be pointed out that is: adapter shaft 33 is actually along arcuate socket 10 and moves down, just will mobile second connecting rod 35 as it, rotary-actuated 36, and pitching actuated piece 41 is so that till throwing off latch plate 42 and locking hole 43, but, the bias force of spring 39 or pulling force can be withdrawn into original position with adapter shaft 33 rapidly, on reference position, adapter shaft 33 contacts with the upper limb of arcuate socket 10, can prevent latch plate 42 and locking hole 43 disengagements thus.Thereby digging of seat cushion 2 will can not cause seat S and following rail 4A release.State when Fig. 5 has represented non-use position that seat cushion 2 is dug to be erect, simultaneously, seat S also is locked in down on the rail 4, can find out from this accompanying drawing: tightening screw 33B is positioned at the upper limb of arcuate socket 10, this just shows that adapter shaft 33 is contacting with the upper limb of arcuate socket 10 under the effect of spring 39 bias forces, thus, rotary-actuated 36 and pressure rod 36B are maintained at the off working state of level, latch plate 42 are not applied any release action.
As can be seen from Figure 5, under the tip-up state of seat cushion 2, second pivot arm 34, second connecting rod 35, rotary-actuated 36 and pitching actuated piece 41 all are in off working state to latch plate 42, thereby it is identical to make latch plate 42 state of living at this moment and seat shown in Figure 2 normally take state.Thereby, in this tip-up state, can operate latch plate 42 from rail 4A disengagement down release lever 38.Because this unlocking operation is basic identical with the unlocking operation of above introducing, be under the normal condition shown in Figure 2 at seat, so will only do concise and to the point description with reference to Fig. 5 to this process.That is to say, shown in the arrow among Fig. 5, bias force against spring 39, in the counterclockwise direction release lever 38 is turned to unlocked position, this will impel first connecting rod 31 to move up conversely, thereby left-hand revolution second pivot arm 34, then, second connecting rod 35, rotary-actuated 36, and generation is mobile in view of the above according to the mode identical with process mentioned above to face upward the actuated piece 41 of bowing, utilize the motion of these parts, latch plate 42 is lifted on the unlocked position according to the direction of arrow among Fig. 4 shown in 1. equally, thereby makes its three lock banking stop 42A and 43 disengagements of cooresponding three locking holes, so just allows seat S to move up in front and back.Equally, in the case, the user can move to desirable location point place with seat S by such operation: the bias force that is overcoming spring 39, with hand release lever 38 is remained on released state, then, release lever 38 is discharged, make it be in Immobile lockup state, thereby three lock banking stop 42A that make latch plate 42 join in three selected locking holes 43, so just seat S are locked at down the ideal position point place on the rail 4A.
Should be noted that: although do not illustrate in the drawings, if but the user digs seat cushion 2 when release lever 38 is remained on released state, then adapter shaft 33 will slide into the lower edge 10B place of this specific arcuate socket 10 along arcuate socket 10, this can cause second connecting rod 35 to move up further simultaneously, make rotary-actuated 36 thus and rotate counterclockwise further from position shown in Figure 4, thereby the degree that the latter half 41-2 that makes pressure rod 36B move to and face upward to bow actuated piece 41 disengages, and then cause pitching actuated piece 41 under the action of gravity of latch plate 42, automatically to turn to horizontal off-position shown in Figure 2, so latch plate 42 descends and joins in the locking hole 43.At this moment, rotary-actuated 36 pressure rod 36B is slightly rotated an angle, thus the described half part 41-2 in addition of close pitching actuated piece 41 (that is to say, do not contact) with this part.Then, when the user with release lever 38 when unlocked position discharges, under the tension of spring 39, this specific release lever 38 is automatically reset to lock position, this will impel adapter shaft 33 to slip back to the upper limb place of arcuate socket 10 rapidly conversely.Therefore, second pivot arm 34 and second connecting rod 35 all are rotated separately inoperative reference position as shown in Figure 2, the result is exactly, correspondingly rotated an angle for rotary-actuated 36, make pressure rod 36B be in the non-operating position of level, as shown in Figure 2, this position is positioned at the top of described second half part 41-2 that faces upward the actuated piece 41 of bowing.Those skilled in the art can understand this above-mentioned a series of actions at an easy rate after having read description above and having understanded accompanying drawing.
Under any circumstance, adopt above-mentioned structure setting, can or be used for bearing pin 35A second pivot arm 34 and the position that second connecting rod 35 couples together are remained on an attachment point substantially, so just allow can finish locking/unlocking operation by operation release lever 38 under two kinds of following situations: seat cushion is dug situation, in this case, seat cushion 2 is dug the non-working condition of erectting; And the seat cushion service condition, in this case, seat cushion 2 is in the running condition of basic horizontal.
Thereby, as can be seen:, will need not any backguy and cable are set between seat cushion and release lever, thereby structure is simplified, and be easy to assemble according to the present invention.
Although above invention has been described; but be understood that the present invention is not limited in those embodiments of being introduced; under prerequisite not, can make various ways to these embodiments and change, replace and acquire departing from the protection domain that limits by appended claims.
