According to first embodiment of the invention be used to the device of automotive headrest bending is comprised: be installed in the housing 10 on top of back plate, described back plate is fixed among the backrest 1a of automotive seat 1; Be pivotally secured in the pillar 22 of the headrest 20 on this housing; Retainer 30, described retainer 30 is installed in rotation on the top of the support 10a on the inside face that is arranged at the housing antetheca, and with the horizontal part 222 that holds pillar 22, described retainer 30 also has the spring 35 of maintenance; Be installed in rotation on the bottom of described support and have the control piece 40 of controlling spring 46, described controlling spring 46 applies elastic force along the direction opposite with the elastic force that keeps spring 35, with the retainer of the horizontal part that prevents to be used to keep pillar 22 since the resilient force of maintenance spring 35 pivot; And main spring 50, described main spring 50 flexibly is installed on the pillar 22, is used to elastic force that headrest is pivoted forward to apply.
Each guide groove 12 all forms, and the width on top is greater than the width of bottom and have the zone that upwards broadens above pan 13.For this reason, the rear end 121 of guide groove forms vertically, and the distance L between upper front end 122 and the upper rear end greater than the distance L between its underpart ', L ' forms the diameter of the horizontal part that is fit to pillar 22.The upper and lower of front end is connected by crooked centre portion r.
As described below, when the headrest 20 from vertical state be pivoted to horizontality-crooked 90 Du that promptly rest the head on-time, this upper front end 122 that can cause the horizontal part 222 of pillar 22 to be directed to groove is blocked, thus the horizontal part 222 that has prevented pillar 22 further pivots.
Hinged component 23 with axis hole 231 is fixedly mounted in the both sides of horizontal part 222.Described axis hole aligns with pan 13 in the outside of sidewall 11, with hold link pin 24 and 24 '.
Therefore, pillar 22 is fixed in the housing 10, with link pin 24 and 24 ' on rotate, in the axis hole 231 of described link pin 24 and 24 ' be fixed on hinged component 23 and the pan 13 of housing 10.When pillar was in vertical position, its horizontal part 222 held and is positioned in the bottom of guide groove 12 and holding tank 17.
Under this state, when headrest 20 pin 24 and 24 ' on forward-promptly in Fig. 2 during conter clockwise-pivot, horizontal part 222 lifts and leaves the bottom of guide groove 12 and holding tank 17.When horizontal part contacts with upper front end 122 and is blocked by it, just can not continue to pivot, thus headrest location and remain on horizontality.
Simultaneously, main spring 50 is wound on the link pin 24, and described link pin 24 is fixed therein in the hole 13 of a sidewall 11.The curved end 51 of main spring is hooked on the horizontal part 222 of pillar, and its other end 52 is fixed in the suppending hole 14, and described suppending hole 14 is formed on one of them sidewall 11 of housing 10.
Therefore, the elastic force of main spring 50 is applied on the horizontal part 222, thereby causes pillar 22 to pivot forward on link pin 24, and promptly conter clockwise pivots in Fig. 2.Thereby headrest 20 can bend to horizontality from vertical state.
The retainer 30 of the heart with axis hole 31 is provided with and keeps groove 32 therein, to align with the holding tank 17 of support 10a.Form in two ends of groove 32 one outwards and curve inwardly twice, have the suspender 33 of suppending hole with formation, thereby make these parts be " U " shape, and be formed with in the preceding bottom of retainer and keep projection 34.
Keep spring 35 to be wound on the retainer shaft 30a, an end 351 of this spring is inserted in the suppending hole of suspender 33, and the other end is hooked in the suppending hole 19 of support 10a.
By this structure, keep the elastic force of spring 35 can make rear-i.e. among Fig. 2 the cw-biasing of retainer 30 to headrest 20.But, because still being maintained at the inclination of retainer, the horizontal part 222 that keeps spring to be in compressive state and pillar 22 keeps in the holding tank 17 of groove and support 10a, therefore headrest remains on vertical state.When the repulsive force that keeps spring clockwise rotates retainer, keep groove to turn to vertical state from heeling condition, help making the horizontal part of pillar leave guide groove 12 and holding tank 17 with main spring.
Be formed with in the rear end of control piece upper surface and be used for first claw 42 that engages with the maintenance projection 34 of retainer 30, be formed with second claw 43 in the place ahead of this first claw, to form step with first claw.Control piece 40 also is provided with binding piece 45 in its back-end, so that the end of backguy 40b is fixed on this binding piece, described backguy is by downward pulling control piece 40 and make it clockwise rotate the effect of playing release control device.Control piece 40 also is formed with suppending hole 44 near second claw.Discharge the opening 16 that backguy 40b passes the bottom 15b that is formed at housing 10, the far-end of this backguy 40b links to each other with a bar (not shown), this bar can be arranged on the side of backrest, is used for discharging backrest 1a and backrest 1a being folded into seat cushions downwards from the stationary state with seat cushions.
When this bar of operation, the stationary state of backrest and seat cushions is removed, and it is also pulled down to discharge backguy 40b, makes control piece 40 clockwise rotate.
That is, the rotation of retainer 30 in the position that keeps projection 34 to be blocked by first claw 42 or second claw 43 by stop.
Controlling spring 46 is in the compressive state that is wound on the 40a, and one end 461 is suspended in the suppending hole 44, and its other end 462 be hooked in the suspension recess 19 of support 10a ' in.
By such structure, the repulsive force of the controlling spring 46 of compression along be applied to retainer 30 on the opposite direction of elastic force be applied on the control piece 40.But because control piece and retainer are prevented from rotating along conter clockwise and clockwise direction respectively under the situation that the maintenance projection 34 of retainer is blocked by first claw 42, so pillar 22 remains on vertical state with headrest, as shown in Figure 6.
When downward pulling discharged backguy 40b and control piece 40 and clockwise rotates, because second claw 43 cooperatively interacts with keeping projection 34, retainer 30 clockwise rotated subsequently.Originally arrange obliquely that with respect to the holding tank 17 of support 10a the maintenance groove 32 of the retainer that lifts with the horizontal part 222 that prevents pillar 22 changes into vertically, so that align with holding tank 17, therefore the horizontal part with pillar 22 discharges from arrested state.Under the impetus of the repulsive force effect of main spring 50 of compression and retainer, pillar 22 and headrest 20 conter clockwise on pin 24 that is connected thereto pivot, and make the horizontal part of pillar and to keep groove lift (seeing Fig. 7 and 8) from holding tank.
Because the horizontal part 222 of pillar 22 is formed on upper front end 122 restrictions of the guide groove 12 in two sidewalls 11, therefore under the horizontal curvature state rotation of headrest 20 by stop.Owing to keep projection 34 to be blocked, so the rotation of retainer 30 and control piece 40 also stops by second claw 43.
Making headrest 20 bend to the required time of horizontality from vertical state should be very short,, should finish the bending of headrest before headrest arrives the upper end of front-row seats backrest that is.Since headrest on backrest 1a to front curve, so backrest can fold into downwards on the seat cushions 1b, and the obstruction that can not be rested the head on.
Simultaneously, after folding backrest 1a turned back to vertical position, therefore the headrest 20 horizontal curvature states that still are held in place on the backrest top should manually be holded up it.
When pillar 22 is pushed upwardly when clockwise rotating on link pin 24, main spring 50 is compressed, and horizontal part 222 enters holding tank 17 and promotes to keep groove 32 downwards.Therefore, retainer 30 rotates counterclockwise, and keeps spring 35 also to be compressed.
Continue this operation, align with holding tank 17 up to the bottom that keeps groove 32.After keeping groove and holding tank aligns, retainer 30 is prevented from rotating counterclockwise, and the centre portion of horizontal part is arranged in holding tank 17 and with respect to the maintenance groove 32 of its slight inclination, and the two side portions of horizontal part is arranged in the narrow bottom of guide groove 12.
Simultaneously, when retainer 30 rotates counterclockwise, keep projection 34 to separate with second claw 43 of control piece 40.Then, control piece rotates counterclockwise under the resilient force of the compressed the controlling spring 46 because 40b of pulling backguy downwards clockwise rotates control piece.
Because first claw 42 of the maintenance projection 34 controlled products 40 of retainer 30 blocks, therefore rest the head on and 20 remain on vertical position with pillar 22, wherein, control piece 40 rotates under the bias voltage of the elastic force of the controlling spring 46 of the direction of rotation of direction and retainer.If this joint of projection and claw is not removed, even then the elastic force of main spring 50 is greater than the elastic force that keeps spring 35, headrest also remains on vertical position.
In other words, even the repulsive force of main spring 50 forces headrest 20 to rotate counterclockwise, the prevention that engages of the also controlled product 40 of the rotation of headrest and retainer 30.Therefore, as long as under the state that retainer 30 controlled products 40 keep, headrest just maintains static.
At the device that is used for making the automotive headrest bending according to first embodiment of the invention, retainer and control piece are rotatably connected on the support 10a.But as the modification of first embodiment, they can be connected on one of two sidewalls of housing, thereby remove support 10a (with reference to the 3rd embodiment that hereinafter will describe).
Figure 10 and 11 is the back views of device that are used to make the automotive headrest bending according to the modification of first embodiment of the invention.
This modification is characterised in that, the modification structures of the pillar 22 that the head rest supporting spare 21 of headrest 20 can be by first embodiment reduces and raises, and wherein, vertical portion 221 and the lower horizontal portion 222 of this first embodiment form as one.
The pillar 22 of this example has vertical portion 221 and the lower horizontal portion 222 that is formed separately from each other.The lower end of vertical portion is connected on the corresponding casing seat 61, and casing seat 61 vertically is installed on (sleeve pipe) seat shell 60, and described casing seat shell 60 is installed in the upper end of backrest 1a.The two ends of horizontal part are fixed by welding on the outside face of described casing seat shell.
Because pillar 22 is connected on the casing seat 61, thereby described pillar can rise or descend vertically, therefore can regulate the height of headrest 20.
Figure 12 is the decomposition diagram of device that is used to make the automotive headrest bending according to second embodiment of the invention; Figure 13 to 15 is lateral plans that the device that is in the different operating state is shown.
According to second embodiment of the invention be used to make that the basic structure of device of automotive headrest bending and first embodiment's is basic identical, with the difference of structure among first embodiment be, retainer and control piece are arranged to by the work that is fitted to each other of single coil spring 70, in the structure of first embodiment, retainer 30 is arranged to clockwise rotate by the elastic force that keeps spring 35, control piece is arranged to rotate counterclockwise by the elastic force of controlling spring 46, thereby these two parts can be worked in succession by these springs.
Because retainer and control piece are arranged to by single coil spring 70 operations, so this device has the following advantages: number of springs and number of assembling steps reduce, and retainer 30 can be operated as integral body with control piece 40.
By this structure, the lower end of retainer 30 and control piece 40 spurs towards each other by the elastic force of coil spring 70.Thereby helical spring elastic force makes retainer and control piece conter clockwise and clockwise rotating respectively.
When retainer 30 rotates counterclockwise, keep groove 32 to form upward opening, and keep groove 32 belows to be formed with locking recess 34a.Claw 42a forms from the middle front part of control piece 40 and stretches out, so that be stuck in the described locking recess.
Be used to spur control piece and make the end of its release backguy 40b that rotates counterclockwise be fixed on the lower end of control piece 40.Backguy and the parts that are associated with it and operation thereof are basically the same as those in the first embodiment.
At the aforesaid device that is used for making the automotive headrest bending according to second embodiment of the invention, when the headrest 20 that is in the crooked state in backrest top is pushed upwardly vertical position, the lower horizontal portion 222 of pillar 22 can clockwise rotate on link pin 24, drop in the narrow bottom of guide groove 12, and promote to keep the lower surface of groove 32 downwards.Therefore, retainer 30 clockwise rotates, thereby keeps groove 32 and the lower vertical that wherein is placed with the guide groove of horizontal part.Then, the claw 42a of control piece 40 enters locking recess 34a and engages under the resilient force of coil spring 70, thereby the rotation of retainer and control piece can be made headrest remain on vertical state by stop.As a result, main spring 50 is compressed owing to the cw of pillar 22 pivots, thereby has the repulsive force of increase.
Under this state, the conter clockwise pivoting action of pillar is by the engage prevention of retainer 30 with control piece 40, and this is because this joint has stoped the repulsive force of the main spring 50 of compression to be applied on the horizontal part 222 pillar 22 conter clockwises to be pivoted.Thereby as long as these two parts are engaged with each other as mentioned above, then the horizontal part of pillar just can't leave maintenance groove 32, and rests the head on and 20 be fixed and fixedly remain on vertical position (seeing Figure 13).
When discharging the lower end of backguy 40b and control piece 40 along horizontal pulling, control piece rotates counterclockwise, and claw 42a and locking recess 34a break away from, thereby makes retainer 30 and control piece disengaging.Along with control piece rotates counterclockwise and the repulsive force of the coil spring 70 that extends is used to spur the lower end of retainer, thereby retainer can rotate counterclockwise and it keeps groove 32 upwards to change (seeing Figure 14).
Along with keeping groove 32 so upwards to rotate, horizontal part 222 breaks away from arrested state, thereby the elastic force of the main spring 50 of compression makes pillar 22 rotate counterclockwise.Therefore, horizontal part leaves the maintenance groove, 20 horizontalitys that bend to as shown in figure 15 of resting the head on simultaneously, thus the backrest of seat can fold on the seat cushions downwards, does not hinder and can not be subjected to headrest.
On the other hand, manually make backrest 1a and crooked headrest 20 turn back to vertical position from the folding position.When manually upwards opening headrest, pillar 22 clockwise rotates on link pin 24, the bottom surface that makes main spring 50 compress and promote to keep groove 32 downwards, thus horizontal part 222 can descend and enter maintenance groove and guide groove 12.
Thereby retainer 30 clockwise rotates, and the following claw that make to keep the groove below moves and promotes claw 42a downwards along claw 42a, thereby control piece 40 can rotate counterclockwise.In case claw is through the claw front end of control piece down, the elastic force of rotating the coil spring 70 that extends owing to retainer and control piece in opposite direction just forces control piece to clockwise rotate, and force claw 42a to enter the locking recess 34a of retainer and engage, thereby retainer and control piece just no longer further rotate.Then, headrest 20 remains on as shown in figure 13 vertical state immovably with pillar 22.
Figure 16 is the transparent view of device that is used to make the automotive headrest bending according to third embodiment of the invention, and Figure 17 and 18 is lateral plans that the operation of the device that is used to make the automotive headrest bending shown in Figure 16 is shown.
Third embodiment of the invention is characterised in that, be used to keep the retainer 30 of horizontal part 222 of pillar 22 wherein and the inside face that the control piece 40 that is used for stoping retainer to rotate releasedly is connected to one of them sidewall 11 of housing 10, anti-shaking on the inside face that support 10b is arranged on housing antetheca 15a.
To illustrate below anti-reason of shaking support 10b will be set.
At the device that is used for making the automotive headrest bending according to first and second embodiment, headrest 20 pillar 22 be arranged on vertically link pin 24,24 in the axis hole that is inserted into pan 13 and hinged component 23 ' on so that vertically pivoting in the scopes of about 90 degree between state and the horizontality.Therefore, pivot on link pin when pillar 22 so that rest the head on when being in vertical position, the pillar horizontal part 222 at place, top of guide groove 12 that is positioned at two sidewalls 11 of housing 10 is forced into and stays the narrow bottom of guide groove.The pillar horizontal part is forced to leave guide groove, so that headrest is in case of bending.The degree of depth of wishing the width of variation on guide groove top and its underpart forms consistent with the track of the horizontal part that rotates on link pin, and wherein, described link pin is fixed in the axis hole of hinged component.But when being installed to hinged component on the pillar or the axis hole of hinged component is alignd with pan, even produce little deviation, horizontal part also is difficult to drop to rightly in the narrow bottom of guide groove.In order to address this problem, the bottom of guide groove forms usually to have greater than the width of pillar horizontal part diameter with greater than the normal required degree of depth.But, by above-mentioned structure, not having at hinged component under the situation of above-mentioned deviation, the pillar horizontal part may not arrive the bottom of guide groove yet, and forms gap g between them, thus pillar may shake above the guide groove bottom.This needs this device to have anti-tilter.
The anti-support 10b that shakes of this embodiment is arranged to, and its top surface is in the height identical with the bottom of guide groove 12 or a little less than the bottom of guide groove 12.In addition, consider the gap between the position that the horizontal part 222 of the bottom of each guide groove and pillar 22 should stop after normally entering guide groove, elastic component 101 with suitable thickness is set on the top surface of anti-tilter, described elastic component 101 is made by elastomeric material, for example rubber, artificial rubber, spring etc.When the horizontal part that descends during near the guide groove bottom, extruding elastic component, the elastic force of this elastic component is used to support horizontal part, thereby even there is gap g between the bottom of guide groove and the horizontal part, can prevent that also described horizontal part from shaking.
Simultaneously, the retainer of first and second embodiment and control piece can be as retainer and the control pieces of the 3rd embodiment.The position of the opening 16 that the release backguy 40b that binding piece that form and control piece 45 links to each other in the 15b of the bottom of housing 10 pass can with first and second embodiment in different.
Though invention has been described at the preferred embodiment that vertically pivots in the scope of about 90 degree between state and the horizontality in conjunction with headrest, can change pivoting angle by the engagement state that changes between retainer and the control piece.
In addition,, discharge backguy and can be arranged to reveal the side or the bottom surface of putting, perhaps replace with trigger bar at seat though the example by the release backguy that is connected with the bar that is used for folding seat is described control setup.
