Fig. 8 is the lateral plan that is similar to Fig. 7, but seat is to be in the process of motion backward, will arrive state shown in Figure 1 at once.
The specific embodiment
Fig. 1 schematically expresses seat of the present invention with lateral plan.This seat has a underframe 20.Described underframe 20 has a longitudinal adjusting device, and this longitudinal adjusting device has a pair of left rail and a pair of right guide rail, and each comprises a base plate rail 22 and a seat slide 24 to guide rail, but only expresses a pair of left rail among the figure.About two pairs of guide rails all be vertically displaceable mutually, that is to say, can be from left to right on the plane of this figure or move from right to left.This displacement occurs in the fore-and-aft adjustment direction.Pin at normality guide rail 22 and 24, for this reason, each is furnished with a buckling and locking device 26 to guide rail.Buckling and locking device 26 in the seat both sides is synchronous mutually.One actuator lever 30 allows manually two buckling and locking devices 26 to be actuated into the releasing position from the normality locked position.
This seat also has a seat disc 32, and it is installed on the underframe 20 and a member 33 is arranged.This seat in addition can be around the back of seat 34 of back of seat axis 36 pivots.The top of back of seat 34 has been provided with a clutch lever 38.Can make back of seat 34 releases realize by activating this clutch lever 38, for example tiltable is to position shown in Figure 4.Clutch lever 38 is connected in one first flexible pipe flexible axle 40, and the bottom of flexible pipe flexible axle 40 is connected in a slide block 41, and this slide block 41 can with a mate concerted action of being fixed in member 33.Slide block 41 and mate form the restraint device of back of seat 34 together.
Forward tilt position at back of seat 34 can be handled actuator lever 30 by flexible pipe flexible axle 40.Do just can make buckling and locking device 26 releases like this.In addition, a memory mechanism 42 also is set.Described memory mechanism 42 is not set when activating buckling and locking devices 26 by actuator lever 30.
In the range of movement of tensioner 52, be provided with a control slide block 58.This control slide block 58 also can be called the direction of adjusting along the longitudinal in the guiding device of control slide block guiding device 60 one and move.But the miles of relative movement that this guiding device 60 allows is very short.Control slide block 58 is connected in peripheral cam 64 by one second flexible axle flexible pipe 62, and peripheral cam 64 is mounted close to back of seat axis 36 and is to be arranged in movingly on the member 33, and member 33 is connected in seat disc 32.Peripheral cam 64 be configured to a pin and be arranged on a stopper pin 66 concerted actions on the back of seat 34.In the position shown in Fig. 1 and 3, peripheral cam 64 is to be in the following of stopper pin 66 and not to be engaged with.In the expression of Fig. 4, stopper pin 66 is in one of the peripheral cam 64 control recess and back of seat is mechanically remained on the position that has turned forward, as shown in Figure 4.Before peripheral cam 64 is left downward position by pivot, it does not allow back of seat to leave the position that turns forward, and can and then (to the place ahead along the vehicle direct of travel) motion left of control slide block 58 be reached with second flexible axle flexible pipe 62 and will make peripheral cam 64 pivots leave downward position.
One restraint arm 68 is arranged on the seat slide 24 pivotly and is close to very much revolving drum 44.The toothed surfaces of this restraint arm 68 and tooth rim 48 concerted actions.In normality, therefore restraint arm 68 also is not biased with tooth rim 48 engagements.When being in this state, seat can be by at the longitudinal adjusting device superior displacement, can or discharge some length of pull unit 50 behind the revolving drum 44 or pull unit 50 is wound up, and this depends on the direction of fore-and-aft adjustment.Restraint arm 68 is to be connected in back of seat 34 by the 3rd flexible axle flexible pipe 70.Specifically, an end of the shell of the 3rd flexible axle flexible pipe 70 is connected in restraint arm 68 correctly, and its other end is connected in an attachment point that is arranged on the member 33.At the top, the mandrel of this flexible axle flexible pipe 70 is connected in back of seat 34.At back of seat 34 by the mandrel tension of the 3rd flexible axle flexible pipe 70 when normality position shown in Figure 1 pivots forward.In the bottom, mandrel is fixed in an arm 72 of actuatable buckling and locking device 26.Therefore, back of seat 34 is pivoted forward can make revolving drum 44 be locked in a side and make and be released at opposite side by the longitudinal adjusting device of restraint.
As shown in Figure 1, when the direction of advancing is watched, first end 51 of pull unit 50 is positioned at the front of revolving drum 44.Near first end 51, this can see too clearly by comparison diagram 1 and Fig. 4 revolving drum 44 gradually when seat is moved forward.For example, as shown in Figure 8, tensioner 52 have one can with the area supported 74 of adjacent part concerted action of control slide block 58.This area supported 74 is matched with control slide block 58 in the normality position, sees Fig. 1.
In actual applications, can carry out following sequence of motion: from representing normality position Fig. 1 of normal use location just, activate clutch lever 38, can tilt fully forward around back of seat axis 36, this means to make it reach position shown in Figure 4 to allow back of seat 34.Activate first flexible pipe flexible axle 40 by clutch lever 38, to allow the recess on the slide block disengaging mate.This state representation is in Fig. 3.At this state, back of seat 34 can be turned forward freely.In Fig. 4, back of seat 34 has been forwarded tilt to such position, and peripheral cam 64 is matched with stopper pin 66 on this position, thereby back of seat 34 is lockable and is prevented to recede.
Begin in the process of turning forward at back of seat 34, the 3rd flexible axle flexible pipe 70 activated, and makes to be pulled to free state at this side buckling and locking device 26, this means that longitudinal adjusting device is unlocked, and is lockable at opposite side revolving drum 44.Pin revolving drum 44 length of pull unit 50 is fixed, thereby the initial position of seat can recover when seat is moved after it travels forward backward, this from Fig. 1 and 3 as can be seen.Seat is restricted and can not be moved beyond position corresponding to the locked lengths of pull unit 50 backward.
Moved forward to from position shown in Figure 3 the position process shown in Figure 4 at seat, revolving drum 44 is first end 51 of close pull unit 50 gradually.This can make pull unit produce too much length.Tensioner 52 can pull unit 50 backward (when direct of travel is watched) draw, this as can be seen from Figure 5, but again tensioner 52 is showed among Fig. 5.Its result, control slide block 58 also is allowed to move backward, and this motion is subjected to the help of a springing.For example, peripheral cam 64 by a spring to C.C.W. rotation direction bias voltage.Control slide block 58 the motion of 60 li of guiding devices allow peripheral cam 64 make progress slightly (to anticlockwise direction) pivot.
When seat, be that is to say when mobile backward from position shown in Figure 4, in the time will making it get back to normality position shown in Figure 1, must apply a power to back of seat 34 seat is pulled back on longitudinal guide.Because back of seat 34 pinned by peripheral cam 64, although power applies and is applied to it, it still remains on the position that turns forward, and is like this before seat almost reaches its initial position as shown in Figure 1 at least.Tensioner 52 can only move within its guiding device, move forward enough far just to be contacted with control slide block 58 on a bit of distance before seat reaches this normality or initial position.This can only take place in last several millimeters of mobile route.When control slide block 58 is tensioned part 52 when moving forward, peripheral cam 64 pivots (rotating counterclockwise) downwards and breaks away from stopper pin 66.This means that back of seat 34 can be pulled its stand up position this moment backward.
The sequence of motion that has below illustrated also is depicted in Fig. 6 to 8.This second exemplary embodiment and above-mentioned first exemplary embodiment have many similarities, and this similarity will no longer be discussed.But their difference will be described.Compare with first exemplary embodiment, now, first end of the tensioner 52 of second embodiment is the lower bodies that are anchored on the front portion of base plate rail 22.Also this first end can be anchored on the front end of close base plate rail 22.
Here, peripheral cam 64 direct and back of seat 34 concerted actions this means that back of seat 34 forms stopper pins 66.Peripheral cam 64 remains a single-arm lever, and the second flexible axle flexible pipe 62 can apply effect to it.In this second exemplary embodiment, springing 56 no longer is a coil spring but a flat coiled springs, and it is arranged on the seat slide 24.Perhaps, it also can be arranged on the base plate rail 22.Clearly, control slide block 58 significantly can be in 54 li distance Y of advancing of its guiding device less than tensioner 52 in its 60 li distance X that can advance of guiding device.This also can find out by comparison diagram 7 and Fig. 8 as can be seen from Figure 8.
