Description
Technical field
The present invention relates to a kind of by claim 1 belt retractor device as described in the preamble.
Background technology
By the known this belt retractor device of EP 1 157 905 B1.A main gear spring is set in known belt retractor device, and it makes an axle that has a seat belt winding section towards the coiling direction pretension.In addition, also be provided with a balance spring, it is set to the directive effect of contrary main gear spring.Balance spring is captiveed joint its outer end on the one hand with ratchet, and is captiveed joint with the ring of slip clutch in its inner on the other hand.Ratchet can be by Locking Device towards the coiling direction locking.
When fastening one's safety belt, wish to reduce by the coiling moment of torsion that the main gear spring is applied on the axle.This moment of torsion that is reduced forms like this, in case promptly the safety strap pintle hook lock pins, ratchet just by Locking Device towards the direction locking of reeling, thus when drive or fellow bus passenger when moving backward the main gear spring strain balance spring.The moment of torsion of main gear spring reduces to be about the amount of the needed moment of torsion of tension balance spring in this case.
If driving in the wrong direction, chaufeur or fellow bus passenger sail the direction motion, that is surpass the operating range of balance spring during towards the motion of the direction of backrest, then the wire spring of slip clutch can be with axle always towards the coiling direction rotation, in order that further reel safety strap when balance spring is moved to retardance by the main gear spring.
Known this belt retractor device has many shortcomings.If the locking of ratchet is because safety disengagement with lock is disengaged, then ratchet rotates towards coiling direction based on the moment of torsion that is delivered on it by balance spring.After balance spring was lax fully by rotatablely moving of ratchet, ratchet stopped the rotation suddenly.The cause that this thing happens is that at first balance spring moves the wire spring of slip clutch to retardance, makes ratchet no longer may continue rotation towards coiling direction.Just throw off up to being further rotated when moving wire spring along coiling direction by axle.Especially when the balance spring of brute force, this may cause excessive rotation, causes infringement and in the worst case even cause the destruction of balance spring then.
Another shortcoming of known safe band automatic extending-contracting apparatus is that the slip clutch reliability that contains wire spring is not enough, although it should still can be towards the coiling direction S. A. when surpassing the operating range of balance spring.
Summary of the invention
The objective of the invention is, advise a kind of failure-free and belt retractor device that can produce economically, long service life.
This purpose reaches by the feature of claim 1.
The design that the present invention is favourable is described in the dependent claims.
Basic thought of the present invention is that balance spring only connects in friction force osed top mode by the type of a slip clutch with ratchet.In that safety is with lock when being lockable, if the number of moving part that the coiling safety strap needs surpasses the possible number of total coils of balance spring, balance spring can continue rotation based on slip clutch after it is wound up into retardance by the main gear spring.Avoiding hindering axle thus rotates towards coiling direction.Accurately and equably work by slip clutch of the present invention, so cause identical subjective impression all the time for the user of safety strap.In addition, by balance spring being designed to the slippage spring, can cancel on the axle circumference otherwise necessary wire spring.
Advantageously, ratchet has an inner periphery, and after balance spring is provided in its complete tensioning, when ratchet by locking and when axle rotates in the take-up direction, along the inner periphery slippage of ratchet.That is to say that slip clutch is made of the inner periphery of balance spring itself and ratchet.Reach or the situation of the maximum operating range of over balance spring under, slip clutch allow balance spring then axle be further rotated along coiling direction.
Then increase static friction and cliding friction between balance spring and ratchet inner periphery in order to increase balance spring in the thrust on the ratchet, establish a bloated spring, balance spring is pressed against on the inner periphery of ratchet by bloated spring.
Structurally and in order to assemble rapidly advantageously, bloated spring is designed to the spring section, and this spring section is packed in the circle of balance spring.
Advantageously stipulate by design of the present invention, a free-wheel clutch is set between axle and balance spring, this free-wheel clutch can be implemented power transmission from the axle to the balance spring at axle on the one hand when coiling direction rotates, and allows the power-transfer clutch section of balance spring to carry out relative motion along coiling direction with respect to axle on the other hand.Free-wheel clutch can make main gear spring rotation pretension balance spring by axle when the ratchet locking.Reduced in this case to be about and be used for the needed moment of torsion of tractive balance spring from the moment of torsion of main gear action of the spring on axle.If the locking of ratchet is disengaged when safety disengagement with lock, then ratchet rotates towards coiling direction based on the balance spring that acts on the pretension above it.Because allow the power-transfer clutch section of balance spring to do relative motion by free-wheel clutch of the present invention, so the unexpected braking of ratchet can not take place when balance spring is reeled fully with respect to axle.Ratchet can rotate with respect to axle along coiling direction with balance spring, until applying kinetic energy by doing work due to friction.
Another advantage of the present invention is, can cancel the ring between balance spring and axle.Owing to save a member, reduced productive costs.
The present invention also has an advantage to be, makes whole device design lessly by the cancellation wire spring.
Stipulate advantageously that by design of the present invention free-wheel clutch comprises a driving device that connects regularly with the axle rotation; And, be connected but between driving device and balance spring, can set up a kind of self-detaching shape sealing.Driving device when the ratchet locking and when axle rotates in the take-up direction by the power-transfer clutch section transmission balance spring of balance spring, so balance spring by main gear spring pretension, and has reduced the main gear spring thus again and acts on moment of torsion on the axle along coiling direction.Power transmission between driving device and balance spring is undertaken by a kind of shape sealing.Shape closure designs between driving device and balance spring is, when its automatic disengagement during along the coiling direction relative motion with respect to axle of power-transfer clutch section, so ratchet can freely rotate around axle or around driving device towards coiling direction with balance spring.
Advantageously, driving device is designed to have at least one and is used for the releasably power wheel of the mount pad of hanging balancing spring.For in chaufeur or fellow bus passenger when the direction of seat backrest is moved backward, the spring of installing is as far as possible directly driven towards coiling direction by power wheel, preferably establish the mount pad of a plurality of circle distribution along power wheel, be used for being connected with the power-transfer clutch section shape sealing ground of balance spring.In this respect advantageously, these mount pads are made of the tooth that radially extends on the power wheel circumference.
Advantageously, balance spring is a kind of driving spring.By be provided with a free-wheel clutch by the present invention, can use some almost with the balance spring of the main gear spring same thickness that is adopted.
By a kind of appropriate design of the present invention regulation, the power-transfer clutch section constitutes in order to set up with the shape sealing of driving device the inner by balance spring.By a design simple in structure, the power-transfer clutch section of balance spring is designed to hook-shaped.Balance spring is suspended on by described hook in the mount pad of driving device, and here, hook-shaped power-transfer clutch section can be crossed the mount pad motion of driving device with respect to axle towards coiling direction.Yet also it is contemplated that the power-transfer clutch Duan Youyi of balance spring independent constituting with balance spring bonded assembly member.
Stipulate advantageously that in order to simplify assembling axle is designed to a plurality of parts that especially can peg graft mutually.Here driving device can with axle or with the axle segment design be one.

The embodiment that represents by accompanying drawing describes the present invention in detail below.
Wherein:
Fig. 1 is by belt retractor device exploded drawings of the present invention; And
The belt retractor device that one of Fig. 2 assembles.
The specific embodiment
Represented a belt retractor device 1 among the figure.Safety strap 2 can be wound on by belt retractor device 1 on the seat belt winding section 3 of axle 4.Axle 4 is made up of two parts and component part comprises seat belt winding section 3 and drives section 5.Axle 4 rotatably is contained in the metal case 6.
In addition, belt retractor device 1 comprises a main gear spring 7, and it is captiveed joint its outer end 8 with plastic casing 9.Plastic casing 9 is connected with metal case 6 by three pin 10 side direction.
In addition, belt retractor device 1 also comprise one with main gear spring 7 adjacent and with the ratchet 12 of the driving section 5 coaxial settings of axle 4, it can be along driving section 5 rotations of two hand of rotation with respect to axle 4.For stable, that side that faces main gear spring 7 at ratchet 12 is established a dish 13, and it and ratchet 12 are designed to one.Dish 13 has one to be used for the central through hole 14 that axle 4 drives section 5.For ratchet 12 sets a Locking Device 15, it comprises that the magnetic actuator 16 of the vertical push rod 17 of a ribbon gymnastics and one are installed as can rotating securing rod 18.In addition, Locking Device 15 also comprises a spring 31 that is used for securing rod 18.Securing rod 18 and tooth 19 cooperatings that are provided with along the ratchet excircle.Locking Device is used for rotatablely moving along coiling direction a latch ratchet 12.Ratchet 12 can rotate along unreeling direction b at any time.When securing rod 18 reclines, on its tooth 19 of ratchet rotary course, jump at ratchet 12.
Adorn a balance spring 20 that is designed to driving spring equally in ratchet 12 inside.Balance spring 20 is not to be connected with ratchet 12 shapes sealing ground, but its outer ring is abutted on the inner periphery 21 of ratchet 12.In order to increase the thrust of balance spring 20 on ratchet 12 inner peripherys 21, adopt a bloated spring 22 that is designed to circumferential spring section, it is contained in the inside of balance spring outer ring, and the outer ring with balance spring 20 is pressed against on the inner periphery 21 of ratchet 12 then.The outer end 23 of balance spring 20 curves inwardly hook-shapedly.Therefore the spring 22 that will expand is fixed on its circumferential position with respect to balance spring 20.Power transmission between balance spring 20 and the ratchet 12 no matter along coiling direction a or along unreeling direction b, all realizes by the slip clutch that the inner periphery 21 by balance spring 20 and ratchet 12 constitutes in friction force osed top mode.
A driving device 24 that is designed to power wheel is set in balance spring 20 inside.Driving device 24 comprises many teeth 25 that radially extend towards coiling direction a bevelled.Tooth 25 is configured for the mount pad 27 of transmission balance spring 20 power-transfer clutch sections 28 at it towards coiling direction a bevelled side 26.Power-transfer clutch section 28 is made of the inner 29 of balance spring 20.This inner 29 hook-shaped ground is inwards towards unreeling direction b bending.By hook-shaped design-calculated power-transfer clutch section 28, can between the tooth 25 of power wheel 24 or side 26 and balance spring 20, set up a kind of shape sealing and be connected.Shape sealing between balance spring 20 and driving device 24 can be freed automatically, thereby power-transfer clutch section 28 can be done relative motion along coiling direction a with respect to the driving section 5 of axle 4.Slide along tooth 25 and 26 opposed mild sides 30, side in the inner 29 of balance spring 20 in this process.
When axle 4 when coiling direction a rotates, from free-wheel clutch a predetermincd tension is delivered on the balance spring 20, so balance spring 20 applies a circumferential predetermincd tension towards unreeling direction b on the driving section 5 of axle 4 by driving device 24 and balance spring 20 or balance spring 20 power-transfer clutch sections 28 formations.
The following describes the mode of operation of belt retractor device 1.
When the coiling safety strap, that is when axle 4 when rotating under the power effect of coiling direction a at main gear spring 7, the driving device 24 that is designed to one with the driving section 5 of axle 4 also rotates towards coiling direction a.At this moment, driving device 24 is by the power-transfer clutch section 28 of its tooth 25 drive balance springs 20, and therefore balance spring 20 is tightened up when ratchet 12 lockings.Here, for the moment of torsion of tension balance spring 20 needed moments of torsion and main gear spring 7 has the opposite effect, so that the moment of torsion of main gear spring 7 has reduced to be used to approximately to strain the amount of the required moment of torsion of balance spring 20.This moment of torsion through reducing acts on the axle 4 towards coiling direction a and acts on then on the safety strap 2, and produces the desired comfortable effect of chaufeur.
When ratchet 12 lockings, if surpassed the operating range of balance spring 20, that is axle 4 be coiling safety strap 2 needed revolutions above total revolutions of balance spring 20 maximum possible, and then balance spring can skid along it towards coiling direction a on the inner periphery 21 of the ratchet 12 of locking.Axle 4 can continue the rotation towards coiling direction a, ties up to until safety strap 2 on the health of chaufeur or fellow bus passenger.The size that depends on the spring 22 that expands can change static friction and force of sliding friction between the inner periphery 21 of the excircle of balance spring 20 and ratchet 12.By the breakaway torque that the spring 22 that expands produces regulation is set.
When opening safety when with lock, the push control rod 17 of magnetic actuator 16 shifts out, so securing rod 18 overcomes the radially outwards revolution of spring force of spring 31 from its lock position.Under the torque drive of balance spring 20, ratchet 12 directly begins rotation along coiling direction a, and this moment, balance spring 20 was lax.The rotation of ratchet 12 is carried out with high speed along coiling direction a.When balance spring 20 safety were lax, the hook-shaped power-transfer clutch section 28 of balance spring 20 was just automatically deviate from from driving device 24 corresponding mount pads 27, and slides on the tooth 25 of driving device 24, pauses fully until ratchet 12 at the latest.When ratchet 12 not during locking, the coiling of safety strap 2 is undertaken by all torsion torque of main gear spring 7.
