Abstract
The utility model relates to a vehicle seat belt system and a method for directing a passenger on a vehicle seat. By the seat belt system, a seat belt can be contracted by a motor and a reel until a passenger is fastened on a vehicle, and then the seat belt can be released for a predetermined length by the motor and the reel so as to make the passenger feel comfortable and allow the passenger to move. When possible collision occurs, if the seat belt has already been manually prolonged by the passenger, then the seat belt is drawn back to the zero position by the motor and the reel, so that the passenger is forced to comfortably return to the correct seat position. In this way, the impact force in accidents is reduced, and as the passenger is seated at the correct position, a vehicle airbag is directed to the passenger.
Description
Technical field
The utility model relates to the field of the passenger's who is used for the vehicle seatbelt.More specifically, the utility model relates to the field of automatic seat safety strap (motorised seat belts).
Background technology
Vehicle accident-proneness.If the impact in the vehicle collision is very big, the passenger may be thrown on the inwall of the vehicle suddenly and is subjected to serious injury.The passenger also may be thrown vehicle outside suddenly.Also might impact act on colleague's the passenger.
Prior art has proposed to use seatbelt that the passenger is fixed in their seat, thereby in the collision accident of misfortune, restriction passenger and make the passenger avoid the promotion of harmful impact.
The seatbelt of type is the length-adjustable seatbelt by means of length-adjustment buckle the earliest.The adjustability of length allows the passenger of arbitrary dimension to use identical safety strap.But,, therefore use trouble owing to must readjust seatbelt so that adapt to the every other passenger who is sitting on the seat.In order to solve this difficulty, proposed to be provided with the self-regulation seatbelt, its medi-spring is biased so that the seatbelt that prolongs is involved in the storage space automatically.The passenger only needs from storage space seatbelt to be prolonged extra length, and the health of crossing him in the seat side, allows spring auto reeling seatbelt be tightened up on the health of seatbelt at him buckle of safety belt of seat.But this seatbelt is convenient to be extended from storage space, and this convenience is abused.In the travelling process, many passengers may tilt to leave the position of correctly taking one's seat.For example, the passenger may lean forward or inclination so that talk or take article, rather than his back of the body rested on the back of seat straightly.If the vehicle stop suddenly when correctly taking one's seat the position when the passenger is not in, so because seatbelt can not suitably limit the passenger, so the passenger may be forced to strike on the vehicle or other passengers.
Prior art proposes, and uses inflatable pneumatic bag to cushion passenger's impact when the vehicle stop suddenly.Air bag is set to the passenger especially and can be banged in the inflatable pneumatic bag.But air bag protection is only optimum when having only the passenger correctly to take one's seat.If the passenger tilts to leave the position of correctly taking one's seat, the passenger may not can be directly pushed in the air bag so.
Therefore, need a kind of system and equipment that can strengthen passenger's safety and reduce correctly not sit in the injury that causes in the vehicle owing to the passenger.
The utility model content
In first aspect, the utility model proposes a kind of seat belt system that is used for the vehicle, comprising: can be from the seatbelt that is used for the passenger is tied up to the seat of the vehicle of seat belt retractor prolongation; Be used for making seatbelt to be retracted to the mechanism of seat belt retractor; It is characterized in that, when detecting may the colliding of the vehicle, trigger described mechanism, so that seatbelt is retracted in the seat belt retractor.
Alternatively, described seat belt system also comprises the collision avoidance system in the vehicle, and described collision avoidance system is used for the possibility of collision detection.
Alternatively, when detecting may the colliding of the vehicle, when described mechanism is triggered; Seatbelt is retracted to predetermined length.
Alternatively, described predetermined length is confirmed as hitching the length of passenger's seatbelt when the passenger rests on its back on the backrest of vehicle seat straightly and takes one's seat.

The specific embodiment
Fig. 1 shows the seat belt system that is used for the vehicle 400, comprises controller 100 and a plurality of seat safety belt assemblies of being controlled by controller 100.
Each seat safety belt assembly 101 comprises and being used for passenger's 300 constraints seatbelt 302 on the seat.Seatbelt is stored in the seatbelt storage space that is called as constriction device.In addition, each seat safety belt assembly 101 comprises motor 102 and spool (spool) 106.Spool 106 links to each other with motor 102 by power-transfer clutch 104.Therefore motor 102 can rotate power-transfer clutch 104, and when power-transfer clutch 104 has engaged spool 106, motor 102 can drive spool 106.
Seatbelt 302 is connected to spool 106, thereby when spool 106 rotated in a direction, seatbelt 302 was reeled around spool 106, and is retracted in the seat safety belt assembly 101 and stores.Obviously, seatbelt 302 is prolonged seat safety belt assembly 101 seatbelt 302 is released from the state around spool 106, this is at counter-rotation spool 106.
Each seat safety belt assembly 101 all is positioned at the vehicle 400, thereby seatbelt 302 can be folding from spool prolongation and the safety strap fixer on passenger's shoulder 308, crosses passenger 300 thereby be pulled.The end of seatbelt 302 has buckle (catch) 204, and it is assemblied near the waist of the opposite side that is fixed on passenger 300 the snap close 304.
For CD-ROM drive motor 102, supply with signal to motor 102 by controller 100.Preferably, signal is pulse wave modulation (pulse wave modulated, i.e. PWM) signal.Pwm signal can saving in energy, because at the lower trough of amplitude in the cycle, motor keeps by continuous drive.In Fig. 1 a, shown PWM.
In Fig. 2, spool 106 is shown as seatbelt 302 and twines around spool 106.When observing in sectional side view, the shape of spool 106 is preferably circle.One side circumferential row of spool 106 is shown a plurality of evenly spaced magnets 200.
Spool positions sensor 202 is arranged in each seat safety belt assembly 101, is used for sensing magnet 200.Spool positions sensor 202 is magnet detector basically, is used to monitor the motion that moves through the magnet 200 of magnet detector when spool 106 rotates.
Usually, spool positions sensor 202 can also detect the rotation direction of spool 106, thereby whether the length-specific that can determine seatbelt 302 has been involved in the spool 106 or from spool 106 and discharges.This means on the direction number of times that the counting indication spool of the magnet 200 by spool positions sensor 202 has rotated and the length that prolongs the seatbelt 302 that from seat safety belt assembly 101.Otherwise, the counting of magnet 200 represent the to withdraw length of the seatbelt 302 in the seat safety belt assembly 101 by spool positions sensor 202 on the opposite sense.
For this reason, controller 100 generally includes the memory device (not shown) of the number of times that is used to write down the magnet 200 that spool positions sensor 202 senses.
The accuracy of the length of the seatbelt 302 that can monitor is determined by the resolution that size provided of magnet 200 each intervals.
In fact,, reduce, and along with more seatbelt 302 is rolled-up, this external diameter increases around the external diameter of the volume of the seatbelt 302 of spool along with more seatbelt 302 is emitted.This changed spool 106 each change the length of represented seatbelt 302.But this variation can be left in the basket and be out in the cold usually.But, if desired, it will be understood by a person skilled in the art that how to calculate so that the exact length of the seatbelt 302 that obtains to emit or roll.
Fig. 3 a shows the passenger 300 in the seat that is sitting in the vehicle 400, and the vehicle 400 for example are the roadlices with seat belt system of present embodiment.In order to use seatbelt, passenger 300 is sitting in the vehicle seat and leans against back of seat straightly.Then, passenger 300 crosses its health along diagonal line pulling seatbelt 302, its waist from its shoulder of its health one side to opposite side.When pulling seatbelt 302 was crossed oneself, seatbelt 302 was released from spool 106.
Then, the buckle 204 on the seatbelt 302 is inserted near the seat part that is fixed on contiguous passenger's 300 waists the snap close 304.Thereby cross passenger's 300 fixed seat safety strap 302.
When the buckle 204 of seatbelt 302 is fixed in the seat snap close 304 and the vehicle 400 during by igniting, controller 100 detects the buckle 204 of seatbelt 302 and is fixed by snap close 304, and send a command to motor 102, thereby seatbelt 302 as much as possible is retracted in the seat safety belt assembly 101 so that spool 106 is rotated along the direction of rolling seatbelt 302.Fig. 3 b display seat seat belt is retracted.
Usually, be applied to the power that being used on the spool 106 be involved in seatbelt 302 by motor 102 and be approximately 30 to 40N.If apply the rotation that the resistance that is equal to or greater than 40N stops spool 106, spool 106 will break away from from power-transfer clutch 104 so, so that prevent further being involved in of seatbelt.Because power-transfer clutch separates with spool, spool no longer significantly moves.Even controller 100 detects motor and still is driven then, the turned position of spool 106 is also almost constant.Controller 100 assert that seatbelt 302 is tightened up facing to the passenger like this.
In case controller 100 senses seatbelt 302 and is tightened up, controller 100 just makes spool 106 break away from from power-transfer clutch 104.Thereby the tension of seatbelt spurs spool spool 106 naturally and rotates slightly on reversing sense.This discharges the seatbelt 302 of little extra length, so that loosen the tension of seatbelt 302, allows seatbelt 302 to relax a bit.This is presented among Fig. 3 c and the 3d.
As shown in Figure 3, the lax slightly length of seatbelt 302 is " zero positions " of the current passenger 300 in the seat of the vehicle 400.Promptly " zero position " is will have the length-specific of the seatbelt 302 of the little extra length that satisfies traveling comfort with the power tension of 40N simultaneously usually on passenger 300 health.
In this stage, controller stops CD-ROM drive motor 102.
" zero position " that obtain seatbelt 302 afterwards, power-transfer clutch 104 keeps breaking away from spool 106, can manually from seat safety belt assembly 101, prolong the seatbelt 302 of extra length, so that give passenger 300 certain traveling comfort and freedom of motion, so that tilt to leave the position of correctly taking one's seat.
In the position of correctly taking one's seat, passenger 300 is sitting in the seat of the vehicle 400, and in the face of the place ahead of the vehicle 400, passenger's back and shoulder rest on the back of seat of the vehicle 400 straightly.If passenger 300 moves its take one's seat position or inclination or lean forward in seat, more seatbelt 302 will prolong from seat safety belt assembly 101.Like this, if the length of the seatbelt 302 that prolongs from seat safety belt assembly 101 is greater than the seatbelt length in " zero position ", assert that then passenger 300 moves from the position of correctly taking one's seat, if collision appears in the vehicle 400, this will be dangerous.
In other words, if passenger 300 correctly and safely takes one's seat, " zero position " is identified as the extreme length that should prolong the seatbelt 302 that comes out from seat safety belt assembly 101, and any extra length will represent that the passenger moves from the position of correctly taking one's seat, perhaps for passenger's size, " zero position " is identified as the minimum length that hitches the required safety strap of passenger, and shorter length is infeasible.
If passenger 300 moves from the position of correctly taking one's seat, more seatbelt 302 may prolong from spool 106, and spool 106 rotates on the direction that allows release seatbelt 302 simultaneously.Simultaneously, 100 pairs of magnets 200 of controller are counted by the number of times of spool positions sensor 202.Like this, for seatbelt 302 is withdrawn into " zero position ", controller 100 makes motor 102 rotating scroll 106 on the direction that is involved in seatbelt 302, the counting of the magnet 200 by reel sensor when the counting of the magnet 200 by reel sensor in the process that is being involved in seatbelt equals seatbelt 302 and is extended.
If the vehicle 400 are under the urgent case of collision, controller 100 causes that spool 106 is withdrawn into " zero position " with seatbelt 302.This is withdrawn into the position of correctly taking one's seat with the passenger.Untie seatbelt 302 at every turn and must rebulid " zero position ", may represent that new passenger 300 has sat down because untie.
Alternatively, in alternate embodiment, in order to guarantee that spool successfully from disengaging of clutch, can be provided with the spring (not shown), in case power-transfer clutch discharges spool, spring is just biased, thus on the safety strap release direction of spool rotating scroll slightly.Spring guarantees low-angle of motor reversing, thereby guarantees that power-transfer clutch breaks away from from spool fully, and guarantees to discharge the seatbelt 302 of little extra length, so that loosen the tension of seatbelt 302.
As an example, in order to monitor possibility of collision, the vehicle 400 are equipped with the collision avoidance system of the object that is used to detect the vehicle 400 the place aheads, for example radar system.This in the art mechanism is known, need not to give unnecessary details at this.It may be noted that radar can detect in the vehicle 400 the place ahead limited distances and has enough existence of large-sized any object.Connect controller 100 so that receive the input that comes from collision avoidance system.When controller receives indication when detecting the signal of object in vehicle the place ahead from radar, controller makes seatbelt be wound up into zero position.
The vehicle 400 of Fig. 4 demonstration such as roadlice 400 are near the unexpected pedestrian 402 on the travel that is positioned at roadlice 400.Radar sensing 406 pedestrians' 402 existence in the car.When detections of radar when being positioned at such object in the motion vehicle 400 the place aheads, if passenger 300 tilts to leave its position of correctly taking one's seat in the car, then controller 100 triggers spool 106 and turns to " zero position " as early as possible, and passenger 300 is pulled back to the position of correctly taking one's seat, thus so that supported opposing collision.
Usually, the power that passenger 300 is retracted the tram is approximately 165N, but this only is an example.This big or small power forces passenger 300 to get back to the position of correctly taking one's seat, and does not injure passenger 300.If passenger 300 is pulled in the position of correctly taking one's seat, passenger 300 can not clashed into any part of the vehicle 400 in collision, because he is correctly limited by seatbelt 302.If collision and airbag aeration are arranged, passenger 300 will be positioned at the position that directly bangs into the air bag (not shown).
Preferably, collision avoidance system can also calculate the distance between the vehicle 400 and the objects in front 402, and spool 106 shrinks the speed of seatbelts 302 and present speed with the vehicle 400, and to arrive the required time of object 402 proportional.Like this, if the very close vehicle 400 of object 402, spool 106 is with very fast contraction so.Otherwise if the not too close vehicle 400 of objects in front 402, spool 106 preferably shrinks seatbelt 302 with the speed that relaxes so.This prevents that passenger 300 from being wrenched suddenly and unnecessarily.
Fig. 5 a shows how passenger 300 leans forward in passenger's 300 seats.Fig. 5 b shows how inclination in passenger's 300 seats of passenger 300.In these positions, passenger 300 does not take one's seat with secured fashion, if the collision of the vehicle 400, seatbelt 302 can not correctly protect passenger 300 to avoid evitable bump.More specifically, if collide the very strong airbag aeration that is enough to trigger, passenger 300 may not be arranged in the optimum position that can bang into air bag.Fig. 5 c shows how passenger 300 is pulled the position of correctly taking one's seat when seatbelt 302 shrinks.This is triggered by the object whether radar detects the vehicle 400 the place aheads.
Fig. 6 shows the example of being determined a series of possible step 600 of " zero position " by controller 100 being used to of carrying out.When the operation beginning, in step 602, controller 100 detects whether seatbelt 302 is fastened and whether the driving engine of the vehicle 400 lights a fire.As mentioned above, the sensor of communicating by letter with controller 100 in the snap close 304 at the seat place by the vehicle 400 detects fastening.Similarly, use suitable sensor to detect the igniting of the vehicle 400.The whole bag of tricks of realizing these steps is known to those skilled in the art, need not to give unnecessary details at this.If seatbelt 302 prolongs from seat safety belt assembly 101 and is buckled in the snap close 304 of contiguous passenger's 300 seats, and if driving engine lighted a fire, then controller 100 will assert that passenger 300 is sitting on the seat.Then in step 606, controller sends instruction driving the motor 102 in the seat safety belt assembly 101, so that rotating scroll 106, thereby the seatbelt 302 that prolongs is reeled and is retracted in the seat safety belt assembly 101 around spool 106.In step 608, monitor the position of spool 106 with the time gap (for example per 1 second or preferably per 0.5 second) of rule.When the contraction of seatbelt 302 was hindered by snap close, spool 106 broke away from from power-transfer clutch 104, even the motor continuous rotation, spool 106 also no longer rotates.In this stage, the seatbelt that discharges little extra length is so that the tension of lax passenger's safety strap on one's body.In step 610, the magnet 200 that controller 100 can sense around spool 106 no longer moves then.In step 616, the counting of the magnet 200 by spool positions sensor 202 sensings is set to zero, and promptly=0, the memory device in the controller 100 is recorded as this " zero position ".This is provided with " zero position ".Then, from this zero position, the motion of the magnet on the caused spool of any detected extra length by the seatbelt of pulling out from spool 106 is counted.Usually, the rotation of spool 106 discharge a direction of more seatbelts 302 from seat safety belt assembly 101 on will just be counted, for example the counting of magnet 200 be+1 ,+2 ,+3
Fig. 7 shows the diagram of circuit that how to use " zero position " on the spool 106 subsequently.As mentioned above, be stored in the memory device of controller 100 according to above-mentioned steps " zero position ".In order to use " zero position ", in step 702, detect the igniting of the driving engine of the vehicle 400, be unlatching so that guarantee the igniting of driving engine.This allows the controller 100 identification vehicle 400 to be in use and is moving.Any time in travelling, passenger 300 may move and leave the position of correctly taking one's seat.When doing like this, the seatbelt 302 of certain-length prolongs from seat safety belt assembly 101.By being counted, the number of times of the magnet 200 that moves through spool positions sensor 202 monitors this length.In step 704, if the radar in the vehicle 400 the place aheads senses the object that may be collided by the vehicle 400, then in step 706, thereby rotating scroll 106 is withdrawn into the length that " zero position " located with seatbelt 302.In step 706, in order to guarantee to reach " zero position ", the counting of continuous detecting magnet 200 when spool 106 backward rotation.For example, in step 708, by from+3 ,+2 ,+1 count down to " zero position ", controller 100 can shrink seatbelt 302.This length with seatbelt 302 returns to predetermined " zero position " length.
Therefore, this embodiment comprises the seat belt system that is used for the vehicle 400, described system comprises the passenger's 300 of the seat that can prolong from seatbelt 302 constriction devices (being the seatbelt storage space), be used for hitching the vehicle 400 seatbelt 302, be used for making seatbelt 302 to be retracted to the mechanism of seatbelt 302 constriction devices, wherein when detecting may the colliding of the vehicle 400, trigger described mechanism.
This embodiment also comprises a kind of method of aiming at passenger 300 in the seat of the vehicle 400, said method comprising the steps of: prolong seatbelt 302 from seatbelt 302 constriction devices, so that passenger 300 is tied up in the seat of the vehicle 400, detect may colliding of the vehicle 400, and seatbelt 302 is retracted in seatbelt 302 constriction devices when detecting.
Though more than described preferred embodiment of the present utility model, it will be understood by those skilled in the art that under the prerequisite that does not deviate from the utility model scope required for protection, can make multiple variation or change aspect design, structure or the operational details.
For example, though described motor 102, power-transfer clutch 104 and seat safety belt assembly 101, it will be understood by those skilled in the art that other mechanical device that is used for making seatbelt 302 be retracted to constriction device also is feasible when possible collision occurs.
In addition, though described the collision avoidance system of the object that is used to detect the vehicle 400 the place aheads that may cause collision, but also can so that cause motor 102 seatbelt 302 be retracted to " zero position " slamming any time trigger controller 100 of drg.But, in more practical method, when the vehicle 400 travel with the speed that is higher than predetermined threshold and slam drg suddenly so that when the vehicle 400 are slowed down, trigger controller 100 and seatbelt 302 is retracted to " zero position " so that cause motor 102.The degree of threshold value and deceleration can be determined during fabrication.
Though shown roadlice in Fig. 4, described embodiment is of value to any vehicle 400, for example train, steamer, aircraft, amusement park ride-on toy or the like.
In addition, can implement the modification of this embodiment in the independently detouchable passenger seat of the vehicle 400, described independently detouchable passenger seat for example is to be fixed to the baby seat on the seat in the car.This baby seat has and the similar seatbelt 302 of the seatbelt of described embodiment, and the difference of the two only is that whole seat safety belt assembly 101 is incorporated into baby seat.Seatbelt 302 can prolong, and for example extends to the inferior horn of the opposite side of baby seat from the last angle of a side of baby seat.The motor 102 that is used to make seatbelt 302 be withdrawn into " zero position " also is incorporated into baby seat.In this case, can trigger seatbelt 302 by the accelerometer that being used in the baby seat detected unexpected deceleration and be withdrawn into " zero position ".Also can use radio communication between car internal controller 100 and the baby seat to trigger the contraction of seatbelt.
In another modification of this embodiment, send " sense of touch " signal to passenger 300 with the form of vibration.When passenger 300 tilts to leave when correctly taking one's seat the position, seatbelt 302 vibrations in case the warning passenger he not in the position of correctly taking one's seat.Alternatively, only provide such vibratory alarm in some cases, if for example travelling of the vehicle 400 surpasses specific speed, for example 70km/ hour, if perhaps passenger 300 has tilted to leave correctly to take one's seat the position above specific time cycle, for example 5 minutes.For such signal is provided, the suitable oscillatory system that is used for vibration seat safety strap 302 is installed in seat safety belt assembly 101.
In another modification of this embodiment, when the vehicle will be with object collision, controller will shrink and surpass the seatbelt that needs, so that return to zero position.Promptly extend to the length that the exterior seatbelt of constriction device is shorter than zero position.Advantageously, this is fixing tightly on the seat with the passenger.
