Description
Technical field
The present invention relates to a kind of continuously controllable back of seat hinge mount, be used for an automobile seat that comprises seat support plate and back of seat.
Background technology
Usually, the back of seat of automobile seat is configured to adjustable tilt, thereby automobile seat can be suitable for corresponding user respectively.Therefore, between seat support plate and back of seat, provide a back of seat hinge mount that is used for the pivot block chair back.Usually, this automobile seat also comprises a underframe, and this underframe is height adjustable and comprises a for example fore-and-aft adjustment mechanism.Project seat support plate is meant and comprises any structure that directly or indirectly is suitable for use as a seat panel and supports a seat insert usually.
Known in power actuated vehicle back of seat be implemented as adjustable tilt to a certain degree, but also have the back of seat that can always tilt to a bed flat position.
The major requirement that is provided with on the back of seat hinge mount is, should allow simple as far as possible and adjust operation in a side easily, and because security reason firmly is connected to the seat support plate at opposite side with back of seat.This is very important, can cause serious injury to the user because just in case meet accident back of seat is turned back.
The known seats hinge mount uses a motor to allow to adjust angle.Although this motor allows to adjust continuously back of seat, its cost is very high and depend on energy supply for operation.Selectively, become known for adjusting the back of seat hinge mount of the machinery of ratchet.These mechanical block chair back hinge mount costs are lower, and need not energy source; But they are continuously controllable not normally.
The normally very complicated structure of adjusting mechanism that allows continuous tilt to adjust, and it is not very convenient to operate.Therefore, reason usually is owing to will implement tilt adjustments continuously, must rotate to adjust to take turns and adjust back of seat many times.The connection in a kind of absolute zero gap can not be provided usually.Even service life begin provide a kind of Zero clearance to connect, but can not avoid the gap repeated usage after to wear and tear.
For example, in European patent 0741056A1 number, shown a kind of common back of seat hinge mount.Especially Fig. 5 has shown a kind of back of seat hinge mount of pure machinery, wherein can only make tilt adjustments with very little amplitude.By all ingear teeth, a component with tooth, can make subcontinuous adjustment, this component with tooth is fixed to back of seat and has and be fixed to the tooth of the adjustment element cooperation of seat support plate.The shortcoming of this embodiment is to guarantee in long-time running that the Zero clearance cooperates.Equally, can not realize real continuous adjustment.
Summary of the invention
The purpose of this invention is to provide a kind of back of seat hinge mount that is used for automobile seat, this back of seat hinge mount allows to adjust continuously the angle of inclination of back of seat.Be contemplated that the back of seat hinge mount need not any motor, but still can operate easily and easily.And, make the back of seat hinge mount guarantee the Zero clearance in its whole length of life.
According to the present invention, realize this purpose by a kind of back of seat hinge mount.
Back of seat hinge mount of the present invention allows continuous tilt to adjust back of seat.Depend on the enforcement of back of seat hinge mount, especially toothed part, back of seat slopes to level, thus automobile seat can reach a bed flat position.In addition, the back of seat hinge mount has only several parts, and very firm.Especially, the quantity of movable member is considerably less.One major advantage also is that component with tooth and pawl element can be interlocked by very thick tooth, thereby realize safety and firm being connected.
Seat support plate and back of seat link together by the back of seat hinge mount.In the bottom of back of seat, component with tooth can be described as and is centered on the pivot axis.By a slotted hole, the pawl element orientation is towards the pivot axis of back of seat, and this back of seat extends through a pivot that is arranged on the seat support plate, but can otherwise move freely, and this pawl element is meshed with component with tooth.Because this moving freely property or the pivotability of pawl element allow continuous adjustment at last.In order to pivot, pawl element also allows to change gradient component with tooth and back of seat therefore.Pawl element is fixed on the desired position by two eccentric disks, these two eccentric disks are installed in for rotation on the seat support plate, and fully load by a spring that is used for them, thereby the opposite face by two bevelleds of pawl element, diagonal angle comes to promote pawl element to component with tooth, thereby the tooth of pawl element is moved into and maintenance is meshed with the tooth of component with tooth.
Unclamp the back of seat hinge mount by a stop mechanism, cause the spring of two eccentric disks opposing tension and rotate, be used to make pawl element to throw off.The pawl element of having thrown off now can pivot and still be meshed with component with tooth simultaneously, perhaps can throw off engagement with component with tooth by the longitudinal travel on the length of slotted hole.When component with tooth and pawl element de-mesh, component with tooth and back of seat therefore can be free around pivot axis.
Advantageously, provide another spring element, be used for when unclamping eccentric disk, the pulling pawl element is thrown off the engagement with component with tooth.Its advantage is just can fully freely adjust back of seat as long as activate a mechanism.
Because pawl element at first is meshed with the nearest tooth of component with tooth, and remains on this position by the eccentric disk of throwing off once more, lock the back of seat hinge mount.
Back of seat hinge mount of the present invention is very little structure, but has the lever of very high driving force owing to the feature of bastard.Because crash-resistant bastard feature, it is no problem that back of seat is synchronously stagnated on each limit, and the back of seat hinge mount also is applicable in the integrated seat.At last, the division of tooth does not influence the adjustment traveling comfort, and can guarantee required Zero clearance enduringly.
Two eccentric disks, pawl element and component with tooth relative to each other are arranged to, but in all lock position generation self-lockings.Peripheral surface of this inclined-plane contact eccentric disk by pawl element realizes, thereby obtains to guarantee the angle of self-locking between vertical and an imaginary line of run-on point by eccentric disk.This angle depends on material, and extremely about 7 degree on when steel runs into steel.Self-locking has prevented that back of seat from causing that component with tooth and pawl element therefore tilt, and removes the contact between two eccentric disks that firmly are fixed to the seat support plate.
For example, eccentric disk can come spring-loaded by the coil spring in the pivot center zone that is arranged at eccentric disk.Described coil spring setting and being implemented as, for mobile pawl element, eccentric disk always is pushed by spring force and enters the direction of guiding component with tooth into.
Selectively, can provide a drag spring, this drag spring links together two eccentric disks, and causes them to move towards each other.By causing that two bars move towards each other, each bar firmly is connected to corresponding in two eccentric disks, thereby described eccentric disk also is caused rotation, thereby for example promotes the inclined-plane of pawl element towards component with tooth by its peripheral surface.
On the principle, the back of seat hinge mount can be made by any suitable material.Yet especially suitable is the material with a resistance, and this resistance allows to observe all automotive safety rules.In this scope, steel is especially suitable material.
Pawl element can advantageously comprise an extendible portion, and this extendible portion is in abutting connection with two inclined-planes and extend between two eccentric disks.On this extendible portion, be advantageously provided a drag spring, the other end of this drag spring firmly is connected to the seat support plate, when unclamping eccentric disk, along the direction pulling pawl element that leaves component with tooth.
The actuating mechanism that is used to discharge the back of seat hinge mount can be any structure.Importantly, it causes that eccentric disk is along allowing pawl element to move away the direction of component with tooth and rotating.On eccentric disk, for example can provide the tie-plate that is connected to eccentric disk, thereby make them, and allow them along another rotation direction idle running along a rotation direction.

Fig. 2 has shown the lateral plan of back of seat hinge mount shown in Figure 1.
The specific embodiment
Fig. 1 and 2 has shown a back of seat hinge mount 20 that connects a seat support plate 22 and a back of seat 24.Seat support plate 22 and back of seat 24 have only been represented part, and simplify significantly.Component with tooth 26 is fixed to the bottom section towards the back of seat 24 of seat support plate 22.Component with tooth 26 is configured to plate shape, and partial parallel extends in seat support plate 22, and is local from wherein outstanding.It pivots around a pivot 28, and a pivot axis X-X is by this pivot 28, and this has caused back of seat also to pivot around pivot 28.Shown in exemplary embodiment in, component with tooth 26 opens towards its free arc tips, and tooth 30 is arranged on the free-ended end side of component with tooth 26.The radius relevant with free arc tips is corresponding to the part of the circular arc that extends around pivot axis X-X.
One pawl element 32 also is fixed to pivot 28 by slotted hole 34.And pawl element 32 can move freely.The extreme length 33 of slotted hole 34 is arranged to, and pawl element 32 can move towards and away from component with tooth 26.Pawl element 32 also has an arcuate zone tooth zone 36, is arranged to cooperate with the tooth 30 of component with tooth 26 in this arcuate zone tooth zone 36.The curvature in arcuate zone tooth zone 36 is therefore corresponding to the free-ended curvature of the arc of component with tooth 26.As Fig. 2 institute best image, pawl element 32 is parallel to component with tooth 26, extends to the free end the zone of slotted hole 34 from band tooth zone 36 always, and perhaps component with tooth 26 is arranged between the seat support plate 22 and pawl element 32 in this zone.This means, pawl element 32 is configured to that step is arranged in cross-sectional plane, thereby the tooth 30 of component with tooth 26 can be meshed with band tooth zone 36, and perhaps the tooth 30 with band tooth zone 36 is meshed, and while pivot 28 extends through slotted hole 34 always and enters component with tooth 26 or a recess that wherein provides is provided.
Component with tooth 32 also has first inclined-plane 38 and second inclined-plane 40, and these two inclined-planes are relative diagonally, and forms a kind of " V " shape together.One extendible portion 42 is in abutting connection with the inclined-plane 38,40, and the main extendible portion of this extendible portion 42 is partly aimed at the longitudinal extension of slotted hole 34.Free end at extendible portion 42 is provided with a drag spring 44, and this drag spring 44 promotes or pulling pawl element 32 leaves component with tooth 26.The length of the power of drag spring 44 and slotted hole 34 is enough to the tooth 30 of mobile component with tooth 26 and throws off the band tooth zone 36 of pawl element 32.
In order to prevent that pawl element 32 and component with tooth 26 from sliping off, two eccentric disks are provided, first eccentric disk 46 and second eccentric disk 48, each is all fixed, but is fixed to seat support plate 22 for the rotation axis Y-Y that rotates rotates.The outside face 50 of eccentric disk 46,48 forms the contact surface of cooperating with inclined-plane 38,40.This means that eccentric disk 46,48 is supported pawl element 32, and therefore supports component with tooth 26 and back of seat 24.Outside face 50 extends into around the pivot center Y-Y of eccentric disk 46,48, and the distance of along the circumferential direction leaving corresponding pivot center Y-Y increases and reduces along other direction along a direction.If eccentric disk 46,48 rotates around corresponding rotating shaft line Y-Y, then pressure is applied on the inclined-plane 38,40 by outside face 50, and rotates release along another.Importantly, eccentric disk 46,48 location and being implemented as is caused the tooth 30 of component with tooth 26 to be moved into tooth 30 with tooth zone 36 by rotation and is meshed, and rotates and mobile fully de-mesh in opposite direction.
If pawl element 32 and component with tooth 26 are meshed, and then realize a self-locking state, thus inclinable seat backrest 24 not.Has only the eccentric disk 46,48 of release, just adjustable bed rearrangement chair back 24.
Advantageously, eccentric disk 46,48 is equipped with spring, thereby they always are applied to spring force on the inclined-plane 38,40, and causes pawl element 32 to be moved into to be meshed with component with tooth 26 and remain there.In current exemplary embodiment, bar 52 firmly is mounted to eccentric disk 46,48, two bars 52 and links together by an eccentric drag spring 54.
With respect to an imaginary minute surface line that extends along pawl element 32, be arranged to a minute surface symmetric mode by pivot 28 and 42, two eccentric disks of extendible portion 46,48.This means, shown in exemplary embodiment in, two bars 52 relative to each other are provided with diagonally, and the distance between two bars reduces along the direction of pawl element 32, and increase along its free-ended direction.Fixed eccentric drag spring 54 respectively at the end of two bars 52, two bars 52 of these off-centre drag spring 54 pullings toward each other.This causes eccentric disk 46,48 to rotate along the direction that the distance between outside face 50 and the corresponding rotating shaft line increases, thereby therefore promotes pawl element 32 to component with tooth 26.
If overcome the power of eccentric drag spring 54, if perhaps rotate eccentric disk 46,48 along opposite direction, then entire mechanism is unclamped, and component with tooth 26 pivots around pivot axis X-X.If eccentric disk 46,48 goes back to then, if perhaps eccentric drag spring 54 discharges once more, then outside face 50 is suitable for the new location of pawl element 32, and keeps pawl element 32 along desired location. Eccentric disk 46,48 also can go back to, thus tooth 30 de-meshs of the tooth of component with tooth 26 30 and pawl element 32, thus tilted seat backrest 24 fully freely.In the desired position, eccentric disk 46,48 goes back to, and perhaps eccentric drag spring 54 discharges once more, and tooth 30 is sought next possible detent positions. Eccentric disk 46,48 is sought position accurately automatically on inclined-plane 38,40, thereby back of seat 24 remains on the desired position.
The present invention is not limited to described exemplary embodiment, but also comprises all embodiment with identical function.For example, can utilize a plurality of different springs.Also can differently implement bar 52, perhaps depend on eccentric disk 46,48 spring type and eliminate fully.
