First pin holding member 52 is installed on the first guide protrusion 33c in the mode that can slide along the vertical direction, and the second pin holding member 53 is installed on the second guide protrusion 33d in the mode that can slide along the vertical direction.That is, on the first pin holding member 52, be formed with the rectangular aperture to the complementation that the first guide protrusion 33c receives, and on the second pin holding member 53, be formed with the rectangular aperture to the complementation that the second guide protrusion 33d receives.First pin holding member 52 keeps above-mentioned tilt lock shotpin 50, and the second pin holding member 53 keeps above-mentioned tilt lock shotpin 51.First pin holding member 52 is biased downwards by coil spring 54a, and the second pin holding member 53 is biased downwards by coil spring 54b.
In the forward portion of the upper surface of the seat bottom 31 of seat main body 30, operating mechanism is installed.Operating mechanism has operator's station 55.Right side on operator's station 55, is provided with as the first operating portion the bank control bar 55a operated leaning device in the mode that can carry out in the longitudinal direction sliding.In addition, the left side on operator's station 55, is provided with as the second operating portion the swivel lever 55b operated rotating mechanism in the mode that can slide in the longitudinal direction.First pin holding member 52 is connected with bank control bar 55a via the control lever 56a extended obliquely upward.In addition, the second pin holding member 53 is connected with swivel lever 55b via the control lever 56b extended obliquely upward.
If bank control bar 55a is forwards carried out tractive, then the first pin holding member 52 slides along the first guide protrusion 33c upward via control lever 56a.Thus, the tilt lock shotpin 50 be kept by the first holding member 52 is also moved upward, and the top of tilt lock shotpin 50 will be removed with the engaging of locking hole 25a.Its result is, becomes the state can carrying out the tilting action of seat main body 30.
The force of coil spring 54a of bank control bar 55a by exerting a force downwards to the first pin holding member 52, thus via control lever 56a rearward position be biased.Therefore, after tilting action, if discharge bank control bar 55a, then by the force of coil spring 54a, bank control bar 55a incites somebody to action rearward location restore, and the top of tilt lock shotpin 50 also will be inserted in locking hole 25a again.
On the other hand, if swivel lever 55b is forwards carried out tractive, then the second pin holding member 53 will slide along the second guide protrusion 33d upward via control lever 56b.With this, the rotation lock shotpin 51 be kept by the second holding member 53 is also moved upward, and each top of rotation lock shotpin 51 is removed with the engaging of lock groove 25b.Its result is, becomes the state can carrying out the spinning movement of seat main body 30.
Swivel lever 55b by the second pin holding member 53 is carried out the force of the coil spring 54b exerted a force downwards, thus via control lever 56b rearward position be biased.Therefore, after spinning movement, if discharged by swivel lever 55b, then will make swivel lever 55b rearward location restore by the force of coil spring 54b, and each top of rotation lock shotpin 51 also will be inserted in lock groove 25b again.
With reference to Figure 12 and Figure 13, the leaning device of child seat 1 and rotating mechanism are described.Figure 12 is the figure be described leaning device and the rotating mechanism of child seat 1, Figure 13 is another figure be described leaning device and the rotating mechanism of child seat 1.In Figure 12 and Figure 13, illustrate each structure to medelling.
As mentioned above, seat main body 30 has that bottom is engaged guide member 40, top is engaged guide member 44 and cap assembly 45.Further, the lower coupling pole 41 be connected via bar link 42 and top pipe link 43 bottom is engaged guide member 40 and top be engaged engage between guide member 44 while the two is linked.The guiding groove 22b of the correspondence of bearing block 20 is run through respectively by each making in a pair top pipe link 43, and by making bar link 42 abut with the medial surface of the inclined-plane 22a of bearing block 20, thus make the slip on the fore-and-aft direction of lower coupling pole 41 and top pipe link 43 directed, and horizontal movement is limited.
In fig. 12, seat main body 30 is in the obliquity place corresponding with the locking hole 25a at the rear in three locking hole 25a.That is, by making to be engaged guide member 40 via bottom and given prominence to tilt lock shotpin 50 engages with locking hole 25a downwards from seat main body 30, thus the obliquity of seat main body 30 is fixed.
And the mode of load during can bear the taking a seat of infant, makes the outside face of the seat bottom 31 of seat main body 30 be supported on the bearing block areal of support 24 of bearing block 20.Bottom is engaged guide member 40 and configures with being slightly separated with the cylinder curved surface 25 of bearing block 20.The above-mentioned outside face of seat bottom 31 is in the tilting action of seat main body 30 and in spinning movement, to slide bearing of bearing block 20 and to be supported on areal of support 24.In addition, bottom is engaged guide member 40 in the tilting action of seat main body 30 and in spinning movement, is separated a little with the cylinder curved surface 25 of bearing block 20.In other words, the above-mentioned outside face of seat main body 30 is to abut with bearing block areal of support 24 all the time and to be determined size, shape etc. by the mode that supports, and bottom is engaged guide member 40 and is determined size, shape etc. in the mode be separated a little with cylinder curved surface 25.
Seat main body 30 by be formed on abutting with bearing the projection 24a point-like of the convex surface shape on areal of support 24 of bearing block 20, thus friction drag is alleviated, and then can slide swimmingly.
In this case, by being removed with the engaging of lock groove 25b by not shown rotation lock shotpin 51, thus the rotary motion of the seat main body 30 around the rotation axis R roughly consistent with the central axis of tilt lock shotpin 50 can be carried out.In addition, tilt lock shotpin 50 and rotation lock shotpin 51 are formed by the metal of carbon steel etc., but are not limited in this.
If make seat main body 30 rotate relative to bearing block 20, the bottom be then installed on seat main body 30 is engaged guide member 40 by under the state making the engaging of lower coupling pole 41 hook 41a engage with the engagement groove 40a of ring-type, rotates together with seat main body 30.Now, lower coupling pole 41 is limited due to the movement of described above its transverse direction, the therefore geo-stationary relative to bearing block 20.Therefore, the engaging hook 41a of lower coupling pole 41 engages and carries out relative sliding in the engagement groove 40a that bottom is engaged the ring-type of guide member 40.
In addition, if make seat main body 30 rotate relative to bearing block 20, the top be then installed on seat main body 30 is engaged guide member 44 by under the state making each top of top pipe link 43 and cylindric guiding wall 44a engage all the time, rotates together with seat main body 30.Now, top pipe link 43 relative to bearing block 20 geo-stationary.Therefore, top pipe link 43 each top to be engaged along top all the time guide member 44 cylindrical shape guiding wall 44a and carry out relative sliding while engaging.
The protective case 46 that cap assembly 45 that guide member 44 covers and upper part connecting part 43 be engaged to top together with top pipe link 43 relative to bearing block 20 geo-stationary.That is, when the top that cap assembly 45 carries out in the rotation along with seat main body 30 is engaged the rotation of guide member 44, maintain and be covered with the state that top is engaged guide member 44, and cap assembly 45 self does not rotate.
Figure 13 represents obliquity from the obliquity at the rear shown in Figure 12 to front and makes seat main body 30 carry out the state tilted relative to bearing block 20.That is, from the state shown in Figure 12, the engaging of tilt lock shotpin 50 with the locking hole 25a at rear is removed, and seat main body 30 is forwards slided along bearing areal of support 24.Next, by making tilt lock shotpin 50 engage with the locking hole 25a in front, thus obliquity is fixed.
The lower coupling pole 41 that links and top pipe link 43 between guide member 40 and top engaging guide member 44 are engaged to the bottom of seat main body 30 and follow the tilting action of seat main body 30, and slide in the longitudinal direction along the guiding groove 22b of bearing block 20.Therefore, seat main body 30 carries out tilting action and spinning movement relative to bearing block 20, and the lower coupling pole 41 be connected via bar link 42 and top pipe link 43 are maintaining and the bottom of seat main body 30 is engaged while guide member 40 and top is engaged the fastening state between guide member 44 all the time, namely, while maintaining the relative position relationship with seat main body 30, the two is linked.
In addition, naturally, seat main body 30 also can to become the mode of the obliquity corresponding with the locking hole 25a of central authorities and to be formed.When seat main body 30 be in the obliquity corresponding with the locking hole 25a of central authorities and with the obliquity that the locking hole 25a in front is corresponding, also can carry out the rotary motion of the seat main body 30 of the rotation axis R around the central axis as tilt lock shotpin 50.
With reference to Figure 14 and Figure 15, the tilting action of child seat 1 and spinning movement are described.Figure 14 is the figure be described the tilting action of child seat 1, and (a) of Figure 14 ~ (d) timing illustrate tilting action.In addition, Figure 15 is the figure be described the spinning movement of child seat 1, and (a) of Figure 15 ~ (d) timing illustrate spinning movement.
In each accompanying drawing of Figure 14 and Figure 15, schematically illustrate three locking hole 25a, two lock groove 25b, tilt lock shotpin 50, rotation lock shotpin 51, bank control bar 55a and swivel lever 55b.In addition, the cylinder curved surface 25 as concave curved surface is illustrated schematically as horizontal surface.In each accompanying drawing of Figure 14 and Figure 15, using the front side of left side as child seat 1, using the rear side of right side as child seat 1.In addition, in each accompanying drawing of Figure 14 and Figure 15, upper figure to comprise the mode of the cutaway view of the line X-X of figure below and the viewpoint illustrated from top, figure below with comprise upper figure line Y-Y, namely along the mode of the cutaway view of the line of the lock groove 25b in left side and the viewpoint illustrated from side.
As being described tilting action, then Figure 14 (a) state forward that is seat main body 30, and for not to the state that bank control bar 55a and swivel lever 55b operates.Tilt lock shotpin 50 engages with the locking hole 25a of the central authorities in three locking holes, and rotation lock shotpin 51 engages with the lock groove 25b in left side.Figure 14 (b) illustrates the state of bank control bar 55a forwards tractive, and illustrates tilt lock shotpin 50 and be moved upward and make with the engaging of locking hole 25a by the state removed.
Figure 14 (c) illustrates in the state keeping making seat main body 30 forwards slide under the state of bank control bar 55a forwards tractive.That is, this action is make seat main body 30 carry out the tilting action tilted relative to bearing block 20.During tilting action, rotation lock shotpin 51 engages with lock groove 25b.Figure 14 (d) is after making seat main body 30 forwards slide, namely after making inclination, makes the action that seat main body 30 is fixed relative to bearing block 20.That is, by bank control bar 55a is discharged, thus bank control bar 55a rearward location restore, and tilt lock shotpin 50 is inserted into and is sticked in the locking hole 25a in front.
As being described spinning movement, then Figure 15 (a) state forward that is seat main body 30, and for not to the state that bank control bar 55a and swivel lever 55b operates.Tilt lock shotpin 50 engages with the locking hole 25a of the central authorities in three locking holes arranged along the longitudinal direction, and rotation lock shotpin 51 engages with the lock groove 25b in left side.Figure 15 (b) represents the state of bank control bar 55a forwards tractive, and represents that rotation lock shotpin 51 is moved upward and makes with the engaging of lock groove 25b by the state removed.
Figure 15 (c) illustrates in the state keeping the rotation axis R making seat main body 30 around tilt lock shotpin 50 under the state of bank control bar 55a forwards tractive to revolve turnback.That is, this action rotates relative to bearing block 20 for making seat main body 30, thus makes seat main body 30 from state forward to the spinning movement of Status Change backwards.During spinning movement, tilt lock shotpin 50 engages with locking hole 25a.Figure 15 (d), for after making seat main body 30 rotate, makes the action that seat main body 30 is fixed relative to bearing block 20.That is, by swivel lever 55b is discharged, thus swivel lever 55b rearward location restore, and rotation lock shotpin 51 is inserted into and is sticked in other lock groove 25b.
As concluded the leaning device of child seat 1 and rotating mechanism, then child seat 1 has: have the bearing block 20 of lower coupling pole 41 and top pipe link 43 as engagement section and have bottom as engaged part and be engaged the seat main body 30 that guide member 40 and top are engaged guide member 44, and when the change of the obliquity of seat main body 30 and the rotation of seat main body 30, the engaging between engagement section and engaged part is maintained.That is, the relative position relation of these parts is fixed all the time.Therefore, child seat 1 is compared with having the existing child seat of leaning device and rotating mechanism, can the simple mechanism that is miniaturized of the less and parts of passage number of packages, and do not relying under the condition of seat main body 30 relative to the position of rotation of bearing block 20, seat main body is tilted.
In addition, in child seat 1, the bottom of the rise part 22 of bottom, i.e. seat bottom 31 and bearing block 20 is configured in due to leaning device and rotating mechanism, therefore when the tilting action of seat main body 30 and spinning movement time, seat main body 30 is stably supported relative to receiving portion 20, its result is, can stably operate.In addition, be configured in the bottom of the rise part 22 of bearing block 20 due to leaning device and rotating mechanism, therefore, it is possible to freely utilize the top of the rise part 22 of bearing block 20.
And, when the tilting action of seat main body 30 and spinning movement time, because leaning device and rotating mechanism externally do not expose, and can not holding finger etc., therefore comparatively outstanding in safety, in addition, also comparatively outstanding in appearance design.
In addition, because the tilt lock shotpin 50 of child seat 1 and rotation lock shotpin 51 are formed by split and are independently operated respectively, therefore, such as compared with situation about according to the overhang of single lock pin, tilting action and spinning movement being selected as the child seat described in patent documentation 1, reliable and stable operation can be carried out by simple mechanism.And, due to the change without the need to carrying out overhang according to the operation expected, therefore compared with the child seat described in patent documentation 1, working accuracy, the assembly precision of each parts of leaning device and rotating mechanism are not strict, its result is, can reduce component costs, manufacturing cost.
In addition, as long as maintain the engaging between bearing block 20 and seat main body 30 between tilting action and spinning movement, then engagement section and engaged part can be arbitrary structures.Such as, also can only have bottom with bearing block 20 and be engaged guide member 40 and top and be engaged any one party in guide member 44, and seat main body 30 has the mode of a side of corresponding lower coupling pole 41 and top pipe link 43 and formed.Bottom is engaged guide member 40 and may not be discoid, but ring-type or polygonal shape.Bottom is engaged guide member 40 and top and is engaged guide member 44 and also can forms with seat main body 30.
Be engaged guide member 40 and top as bottom and be engaged connecting member between guide member 44, lower coupling pole 41, bar link 42 and upper part connecting part 43 also can form.And, although lower coupling pole 41, bar link 42 and upper part connecting part 43 are engaged guide member 40 and top and are engaged guide member 44 and engage in rise part 22 side and the bottom at the rear of the child seat 1 of seat main body 30, i.e. bearing block 20, as long as but can seesaw corresponding with the tilting action of seat main body 30 be carried out, then also can be other configuration.
Although define three locking hole 25a on the cylinder curved surface 25 of bearing block 20, but it also can be more than two or four.That is, corresponding with the number of locking hole 25a obliquity can be set as arbitrary number, and these positions may not be equally spaced.In addition, although be formed with a pair lock groove 25b abreast relative to Central Line H on the cylinder curved surface 25 of bearing block 20, but also can be formed relative to Central Line H be arbitrary angle, such as orthogonal lock groove.That is, except the state forward of seat main body 30 and backwards except state, can also be formed towards the mode of the transverse state of transverse direction so that infant can be set to.Under this transverse state, also can by transversely arranging multiple locking hole and enabling tilting action carry out.
In addition, as described above, child seat 1 by carrying out tractive to bank control bar 55a thus seat main body 30 can being made to tilt, and by carrying out tractive to swivel lever 55b thus seat main body 30 can being made to rotate.Suppose to carry out these tilting actions and spinning movement, then seat main body 30 will depict complicated uncertain track, thus likely can collide with operator simultaneously.Therefore, child seat 1 is formed can not carry out the mode of tilting action and spinning movement simultaneously.
With reference to Figure 16 and Figure 18, the operating mechanism of bank control bar 55a and swivel lever 55b is described.Figure 16 is the figure be described the operating mechanism of child seat 1, Figure 17 is another figure be described the operating mechanism of child seat 1.In Figure 16 and Figure 18, top is the rear of seat main body, and below is the front of seat main body 30.
Operating switch 57 is the parts of thick plate-like, and is formed shape, the such as crescent or Cyclic dart shape with bending side.Operating switch 57 in the central portion office is installed on operator's station 55 in the mode that can rotate around set pin 57a by set pin 57a.On the side of bending outside, the i.e. rear side of the two end portions of operating switch 57, be formed towards the front of seat main body 30 and the bearing surface 57b expanded outward.In addition, capped from top by bank control bar 55a and swivel lever 55b due to operating switch 57, therefore cannot visually confirm from outside.
Control lever 56a is linked with bank control bar 55a by bar holding member 58a, and control lever 56b is linked with swivel lever 55b by bar holding member 58b.Namely, the end of control lever 56a bends upward, namely in the drawings relative to paper vertically towards the bending of nearby direction, the bar holding member 58a being formed L-shaped is accordingly by chimeric from top, namely vertically chimeric from nearby direction relative to paper in the drawings and linked.Also be same structure about bar holding member 58b.In addition, bar holding member 58a and bar holding member 58b also can form with bank control bar 55a and swivel lever 55b respectively.
Next, the action of operating switch 57 is described.If bank control bar 55a forwards, is namely pulled downwards in the drawings from the state of the operating mechanism shown in Figure 16, then bar holding member 58a forwards will move together with control lever 56a.Now, first top, the i.e. fore-end of bar holding member 58a abut with the bearing surface 57b of operating switch 57, and operating switch 57 is rotated around set pin 57a.If bank control bar 55a is pulled further, then as shown in figure 17, bank control bar 55a stops abutting with the retainer 55c of operator's station 55.
In this case, the bearing surface 57b of postrotational operating switch 57 abuts with the side of bar holding member 58a, and other top, the i.e. fore-end of bar holding member 58b abut with the bearing surface 57b of the opposing party of operating switch 57.Therefore, the movement of swivel lever 55b is abutted with the bearing surface 57b of operating switch 57 by the top of bar holding member 58b and is prevented from.In other words, under the state that the bearing surface 57b of rotated operating switch 57 abuts with the side of bar holding member 58a, in the mode that the fore-end of bar holding member 58b of the opposing party abuts with the bearing surface 57b of the opposing party of operating switch 57, determine the shape of the crescent of operating switch 57 or Cyclic dart shape.
At tractive under the state of bank control bar 55a (Figure 17), tractive can not be carried out to swivel lever 55b, on the contrary, at tractive under the state of swivel lever 55b (Figure 18), tractive can not be carried out to bank control bar 55a.If make the bank control bar 55a of forwards tractive or a side of swivel lever 55b return to original position, then bank control bar 55a or swivel lever 55b forwards can be carried out tractive.Therefore, according to such operating mechanism, prevented the action simultaneously of leaning device and rotating mechanism by simple mechanism, namely can realize the operation of alternative safely.
In addition, because child seat 1 is by means of only operation bank control bar 55a or swivel lever 55b being carried out to tractive and just can carry out inclination for seat main body 30 and rotation, therefore also can one-handed performance, and can freely use another hand.In addition, even if operated operating mechanism by one hand, also can stably operate.
In addition, as described above, tractive is carried out to a side of bank control bar 55a or swivel lever 55b, to operating switch 57 abuts with the side of bar holding member 58a, even if do not make bar holding member 58a slide, at the time point that the top of bar holding member 58a makes operating switch 57 have rotated, the slip of the opposing party of bank control bar 55a or swivel lever 55b also can be limited.That is, operating switch 57 also can be only the parts etc. of rectangle.In addition, the operating mechanism with above-mentioned operating switch 57 can not only be applied to the field of child seat, also can be applied to existence and stably realize in the other field of the demand of the operation of alternative.
In addition, if special in Fig. 3, then as described above, the opening 26 of rectangle is formed with on the top of the rise part 22 of bearing block 20.That is, in child seat 1, by leaning device and rotating mechanism being configured in the bottom of the rise part 22 of seat main body 30 and bearing block 20, thus opening 26 can be formed on the top of the rise part 22 of bearing block 20.Opening 26 can be utilized as handle during carrying child seat 1.
In addition, in opening 26, as shown in Figure 4, the mechanism with various function or device 90 can be carried.Thus, bearing block 20 can have the function beyond the supporting functions of seat main body 30.Particularly under the state backwards of seat main body 30, such as, also can carry photographic camera and rest image or animation be taken, thus protection people etc. can be observed the situation of the infant taken a seat by mobile phone, auto-navigation system etc.In addition, also can carry read-out, enable infant appreciate image.In addition, also can carry sound equipment, enable infant appreciate sound.In addition, also electric fan, interior environment system, illumination equipment etc. can be carried.In addition, the ion generating device discharged in air by ion by plasma discharge etc. can also be carried.According to such ion generating device, can expect the sterilization of so-called air, dedusting, sterilization, organic substance decomposing and deodorizing air purification effect, using infant, the protection hair of people, the hair care of the maintenance of skin as object and the effect etc. of facial skin care.In addition, in order to these devices etc. being set to and can exchanging simply, these devices etc. also can carry via fabricated section.
In order to use the electric equipment be equipped on opening 26, also battery can be configured in the inside of bearing block 20 in tradable mode, or also the Cigarette lighter of vehicle can be utilized as power supply.Be preferably from the power supply of battery, Cigarette lighter etc. to the power lead of electric equipment, in the mode of not interferenceing with tilting action and the spinning movement of seat main body 30, and to carry out distribution through the lower surface of child seat 1 and the mode at the back side, or in the mode of the inside through bearing block 20 distribution.
In addition, naturally, opening 26 also can be shape, the such as circle beyond rectangle.In addition, opening 26 can run through towards rear, may also be only recess.And, opening 26 as described above not only can be applied to the child seat that can carry out relative to the tilting action of the seat main body of bearing block and the type of spinning movement, also can be applied to seat main body be fixed on type in bearing block, seat main body with can relative to bearing block carry out dismounting mode and in mounted type.
In addition, child seat is protected to make it from the impact this purpose acted on vehicle from when colliding to infant, requires to have higher impact resistance.Dent resistance by the child seat of just collision rift relative to the just displacement of collision rift of the displacement of the seat of vehicle, reason and displacement of the motion of fitfull child seat of causing of the counteraction caused etc. and being verified out.In order to realize higher impact resistance, child seat is preferably securely fixed on the seat of vehicle.Usually, child seat fixing in seat can be used to possess the seatbelt of seat safety belt apparatus.The seat safety belt apparatus that the seat of vehicle possesses has: seatbelt, possess the hyoplastron penetrating seatbelt tongue piece and seatbelt can be made to carry out the clasp of dismounting.
About this point, with reference to Fig. 4, child seat 1, as stated, is formed with safety strap engaging protrusion 27 at the rear portion place of the left and right of the base portion 21 of bearing block 20 above.Bearing block 20 is being arranged under the state on the seat of vehicle by safety strap engaging protrusion 27, is configured in the position that engages with tongue piece or the clasp 91 of seat safety belt apparatus from rear side.In other words, safety strap engaging protrusion 27 is formed to cross over length to a certain degree, so as can the position of the tongue piece different from according to vehicle or clasp 91 corresponding.In addition, as long as safety strap engaging protrusion 27 can engage with the tongue piece of seat safety belt apparatus or clasp 91, also can as the safety strap engagement groove of channel-shaped.
Tongue piece or the clasp 91 of seat safety belt apparatus are configured near the seat surface of the seat of vehicle usually, and rigidity is higher compared with the seatbelt of seat safety belt apparatus.Therefore, by making the tongue piece of such seat safety belt apparatus or clasp 91 engage with the safety strap engaging protrusion 27 of bottom of bearing block 20, particularly bearing block 20 or safety strap engagement groove being formed on child seat 1, thus can be fixed bearing block 20 more firmly.Its result is, can realize higher impact resistance.
In addition, can not misplace or come off to make tongue piece or clasp 91 but engage more reliably, safety strap engaging protrusion 27 or safety strap engagement groove are preferably, the recess between the bearing block 20 engaged with tongue piece or clasp 91 and safety strap engaging protrusion 27 or the cross sectional shape shape acutangulate mode vertical with length direction of safety strap engagement groove and be formed.In addition, safety strap engaging protrusion 27 or safety strap engagement groove also can not engage with tongue piece or clasp 91, and engage with the seatbelt of seat safety belt apparatus.In the case, be fixed by the bottom of the bearing block 20 by child seat 1, thus can be fixed securely compared with existing child seat.In addition, safety strap engaging protrusion 27 also can with bearing block 20 split formed.
Above-mentioned this safety strap engaging protrusion 27 or safety strap engagement groove not only can be applied to the child seat that can carry out relative to the tilting action of the seat main body of bearing block and the type of spinning movement, also can be applied to seat main body be fixed on type in bearing block, seat main body with can relative to bearing block carry out dismounting mode and in mounted type.
Child seat 1 realizes higher impact resistance to suppress relative to the displacement of bearing block 20 seat main body 30, has the multiple supporting-point being directed to impact.That is, such as, when vehicle is from head-on crash to object, child seat 1 entirety be subject to front to force of inertia.Now, bearing block 20 is fixed by the seatbelt of vehicle, in contrast, seat main body 30 is not fixed by the seatbelt of vehicle.Therefore, seat main body 30 will forward direction displacement, but by abutting with bearing block 20 in supporting-point seat main body 30 and being supported, thus make the displacement of seat main body 30 suppressed.
About this point, with reference to Figure 10, as mentioned above, in child seat 1, each top and top due to top pipe link 43 are engaged guide member 44 and engage, because which form supporting-point A.Namely, make in the collision due to vehicle child seat 1 entirety be subject to front to force of inertia, each top being configured in the top pipe link 43 of bearing block 20 side be directly fixed on the seat of vehicle is supported being engaged guide member 44 towards rear to the top being configured in seat main body 30 side.Its result is, when vehicle collision is to object, seat main body 30 relative to the displacement forwards of bearing block 20 by suppressed.
Similarly, the supporting wall 28a be formed on inside leading section that top is engaged collision areal of support 44b on the outer peripheral face of guide member 44 and bearing block 20 defines supporting-point B, and top is engaged guide member 44 and is installed on seat main body 30.In addition, the bottom be installed on seat main body 30 is engaged the upper surface 40d (Fig. 8) of the ring-type of guide member 40 and defines supporting-point C to the bottom of the abutment wall 23a that the main body reception opening 23 of bearing block 20 is determined.In Fig. 10, supporting-point C be in the bottom of the abutment wall 23a of bearing block 20, particularly rear end part and bottom are engaged the rear end part of the upper surface 40d of guide member 40.
Supporting-point C, according to the obliquity of seat main body 30, also can be the left-right parts that left-right parts in the bottom of the abutment wall 23a of the ring-type of bearing block 20 and bottom are engaged the upper surface 40d of guide member 40.Namely, the upper surface 40d being engaged guide member 40 with bottom is formed the mode of supporting-point C with the bottom of the abutment wall 23a of bearing block 20 in arbitrary obliquity, larger compared with the width L (Fig. 5) that the diameter that bottom is engaged guide member 40 is formed to receive with the main body of bearing block 20 transverse direction of opening 23.Thus, in child seat 1, prevent the situation being incorporated in the seat main body 30 in main body reception opening 23 and coming off from bearing block 20.
Child seat 1 by having supporting-point A, B, C, thus inhibits seat main body 30 relative to the displacement of bearing block 20 especially, that is, inhibit seat main body 30 relative to bearing block 20 displacement forwards.Its result is, can realize higher impact resistance.In addition, because supporting-point A, B, C are configured in the bottom of the seat bottom 31 of child seat 1 and the rise part 22 of bearing block 20, therefore bearing block 20 can more stably support seat main body 30.In addition, because bearing block 20 is by multiple supporting-point A, B, C and support seat main body 30, thus impact is disperseed, and therefore, it is possible to the material forming bearing block 20 and seat main body 30 is changed to the resin etc. of more light weight from metal etc., can also cutting down cost.
In addition, bearing block 20 and seat main body 30 do not need to abut at supporting-point place all the time, can be separated a little yet and be set to the only abutting when colliding.In addition, child seat 1 also can be formed only to have the mode of a supporting-point A, also can be formed to have the mode of two supporting-point in supporting-point A, B and C, can also with have three supporting-point A, B and C mode and formed.In addition, the supporting-point for realizing higher impact resistance is not limited in three above-mentioned parts.Namely, the part of the seat main body 30 abutted with bearing block 20 is engaged the forward portion of guide member 44 and rear portion, also comprises the bottom of more below compared with these forward portion and rear portion and be engaged on the inferior portion of guide portion 40 comprising top, can form arbitrarily.
Be described with reference to the height adjustment mechanism of Figure 19 to Figure 22 to baby safety band 70 (Fig. 1).Figure 19 is the amplification stereogram at the back side of child seat 1, Figure 20 is the decomposition assembling figure of a part for the height adjustment mechanism of the baby safety band of child seat, Figure 21 is the figure be described the height adjustment mechanism of the baby safety band 70 of child seat 1, Figure 22 is another figure be described the height adjustment mechanism of the baby safety band of child seat 1.In addition, in Figure 19, backplate 68 described later is omitted description.
Child seat 1 in order to retrain safely infant relative to child seat 1, have the seatbelt that the seat that is equivalent to vehicle possesses, the baby safety band 70 of wide cut.Baby safety band 70 is configured in the left and right of back-rest 32 front surface of seat main body 30 respectively, and the baby safety band 70 of left and right is bonded to the health front of infant.Therefore, baby safety band 70 runs through back-rest 32 and forwards extends from the rear of the back-rest 32 of seat main body 30, and runs through the face of taking a seat, i.e. seat bottom 31 and extend downwards, and is fixed by the part of the below of seat bottom 31.
The height of the position of the back-rest 32 run through from the face of taking a seat of seat main body 30 to baby safety band 70, i.e. baby safety band 70, needs the sitting height according to infant and regulates.Therefore, child seat 1 has the height adjustment mechanism of baby safety band 70 to suitably regulate the height of baby safety band 70.
Therefore, on the back-rest 32 of seat main body 30, be formed along the vertical direction, namely short transverse extend two openings 36.These openings 36 across the central authorities of back-rest 32 column sections 37 and symmetrically formed, and in the height direction using across and as the height of baby safety band 70 and the mode of required scope and being formed.Via these openings, comprise be configured in back-rest 32 front surface on above-mentioned head rest plate 60 moving part 61 with relative to back-rest 32 can along short transverse slide mode and be mounted.
Moving part 61 has: head rest plate 60, and it is configured on the front surface of back-rest 32; Rotating bearing component 62, it is configured on the back side of back-rest 32, and is installed on head rest plate 60 via two openings 36 of back-rest 32; First engaging part 63, it is installed on rotating bearing component 62; Second engaging part 64, it is installed in the first engaging part 63.In addition, in fig. 20, rotating bearing component 62, first engaging part 63 and the second engaging part 64, relative to back-rest 32 and head rest plate 60, are described to make clear with being slightly enlarged.In addition, although head rest plate 60 is owing to keeping baby safety band 70 via channel opening 60a, therefore constitute band holding member, but also can be formed in the mode of being undertaken keeping by miscellaneous part.
On head rest plate 60, in order to make baby safety band 70 pass, thus on the position that two openings 36 with back-rest 32 are corresponding respectively, be formed with two channel opening 60a with the roughly the same width with opening 36.Above each channel opening 60a and the central vicinity of head rest plate 60, be formed with the installation portion 60b rearward outstanding via the opening 36 of back-rest 32.In the below of each channel opening 60a and the central vicinity of head rest plate 60, be formed with the engaged beam 60c rearward outstanding via the opening 36 of back-rest 32.On the top of each engaged beam 60c, be formed with the connecting hole 60d run through along above-below direction.
On the right side of the left side of left channel opening 60a and right channel opening 60a, be formed rearward outstanding via the opening 36 of back-rest 32 and to the flat back plate 60e of short transverse expansion.On back plate 60e, be formed with the recess 60f that columned engaging rod 65 described later is received.In addition, at the more below place of each channel opening 60a, be formed with the height and position that do not rely on head rest plate 60 and all the time towards two vent openings 60g that each opening 36 is open.
Rotating bearing component 62 has: housing 62a, give prominence to upward from housing 62a rectangular flat shape protective bulkhead 62b, from the rearward outstanding flat first knob 62c of housing 62a.Be mounted relative to the installation portion 60b (Figure 19) of the opening 36 and outstanding head rest plate 60 that run through each back-rest 32 by housing 62a, thus head rest plate 60 and rotating bearing component 62 are installed integratedly.Now, the column sections 37 of back-rest 32 is configured between head rest plate 60 and rotating bearing component 62.Protective bulkhead 62b prevents the hand of operator from touching the column sections 37 of seat main body 30 when the operation of moving part 61.
First engaging part 63 has the main element 63a of box like.The back side of main element 63a is formed the opening 63b of rectangle.The top of main element 63a around the mode of the rotation axis rotation extended transversely, can be installed on the housing 62a of rotating bearing component 62 with the first engaging part 63.In addition, at the bottom place of main element 63, be extended with the engaging rod 65 of tubular respectively towards left and right foreign side.Engaging rod 65 has therein the reinforcing rod 65a for reinforcing be inserted into across left and right.Reinforce excellent 65a to be formed by the metal of carbon steel etc., but be not limited in this.
On the back side of back-rest 32, on column sections 37 and the left side of left opening 36 and the right side of right opening 36, be formed with engaged curved face part 38.Engaged curved face part 38 has following structure, namely, receive the mode of columned engaging rod 65 with the part and being easy to comprising the barrel surface extended transversely and form the concave curved surface of entrance largo, alignment in the horizontal and be equally spaced configured with multiple in the height direction.
By making the engaging of the first engaging part 63 rod 65 engage with the concave curved surface of the arbitrary line of engaged curved face part 38, thus head rest plate 60 can be adjusted on arbitrary height and position relative to back-rest 32.Now, the engaging rod 65 of the first engaging part 63 engaged with engaged curved face part 38 is also received in the recess 60f of the back plate 60e of the head rest plate 60 slided along short transverse together with the first engaging part 63.In addition, the first engaging part 63, and to be biased to the hand of rotation that engaging rod 65 engages with the engaged curved face part 38 of back-rest 32 by the torsion spring 63c of left and right be integrally formed in the inside of rotating bearing component 62.
Second engaging part 64 is, can in the inside of the main element 63a of the first engaging part 63 parts of tabular slided along the vertical direction, and it is biased downwards by coil spring 64a.In the lower end of the second engaging part 64, be formed in left and right from the main element 63a of the first engaging part 63 a pair engagement pin 66 outstanding downwards.Each engagement pin 66 by being inserted in the connecting hole 60d of the from the beginning engaged beam 60c that backup plate 60 is outstanding via opening 36, thus engages with head rest plate 60.In addition, the second engaging part 64 has the flat second knob 64b rearward outstanding via the opening 63b of the rectangle of the first engaging part 63.
With reference to Figure 21, the operation of the height regulating baby safety band 70 is described.Figure 21 is the figure be described the height adjustment mechanism of the baby safety band 70 of child seat 1 as mentioned above, and is the roughly longitudinal section of the Width central authorities of running through seat main body 30, i.e. moving part 61.First, the first knob 62c of rotating bearing component 62 and the second knob 64b of the second engaging part 64 is held simultaneously, and on the first knob 62c direction, the second knob 64b is lifted (Figure 21 (a)) upward.That is, relative to the first engaging part 63, the second engaging part 64 is lifted upward.This action case, as on the upper surface by thumb being placed on the first knob 62c, makes forefinger and middle finger touch the lower surface of the second knob 64b and lift upward and carry out.By the second engaging part 64 being lifted upward relative to the first engaging part 63, thus the engagement pin 66 of the second engaging part 64 is removed with the engaging of the connecting hole 60d of the engaged beam 60c of head rest plate 60.Its result is, the first engaging part 63 becomes the state (Figure 21 (b)) that can rotate relative to rotating bearing component 62.
And implement the action lifted upward by the second knob 64b of the second engaging part 64 if continue, then the first engaging part 63 rotates relative to rotating bearing component 62.With this, the engaging rod 65 of the first engaging part 63 is removed with the engaging of the engaged curved face part 38 at the back side of back-rest 32.Its result is, head rest plate 60 becomes can relative to back-rest 32 along the state (Figure 21 (c)) that short transverse is slided.In this case, by making the head rest plate 60 being inserted through baby safety band 70 in channel opening 60a slide in the height direction relative to back-rest 32, thus baby safety band 70 can be made to slide into required height.
At this, make the engaging of engagement pin 66 by under the state that relieves the second engaging part 64 being lifted upward relative to the first engaging part 63, if make the first engaging part 63 rotate relative to rotating bearing component 62, then being limited relative to the slip of the first engaging part 63 of the second engaging part 64.About this point, be described with reference to Figure 22.Figure 22 is another figure be described the height adjustment mechanism of the baby safety band of child seat 1 as mentioned above, and is the longitudinal section of the side that comprises the second engaging part 64.In fig. 22, description is omitted about the parts beyond the first engaging part 63 and the second engaging part 64.
With reference to Figure 22, the side of the second engaging part 64 is formed with locking protrusion 64c (also with reference to Figure 20), and is formed with locking recess 62d in the inside of the housing 62a of rotating bearing component 62.From the state of Figure 22 (a), the second engaging part 64 is lifted (Figure 22 (b)) upward relative to the first engaging part 63, next relative to rotating bearing component 62, first engaging part 63 is rotated.Thus, the locking protrusion 64c of the second engaging part 64 is made to engage (Figure 22 (c)) with the locking recess 62d of rotating bearing component 62.Its result is, being limited relative to the slip of the first engaging part 63 of the second engaging part 64.
Therefore, even if hypothesis makes the lift power of the second knob 64b of the second engaging part 64 weaken in this case, but due to the force of coil spring 64a, engagement pin 66 also can not be given prominence to again.In other words, second engaging part 64 of having slided upward is configured to safely, only otherwise under the state that engages with the engaged curved face part 38 of back-rest 32 of the engaging rod 65 being in the first engaging part 63, then the second engaging part 64 would not return to original position.
After making baby safety band 70 slide into required height, in order to be fixed baby safety band 70 at this At The Height, thus only need implement above-mentioned a series of action on the contrary and just can.That is, relative to rotating bearing component 62, first engaging part 63 is rotated, and the engaging of the first engaging part 63 rod 65 is engaged with the engaged curved face part 38 of back-rest 32.Thus, the engaging between the locking protrusion 64c of the second engaging part 64 and locking recess 62d of rotating bearing component 62 is removed.Next, relative to the first engaging part 63, second engaging part 64 is slided downwards, and the engagement pin 66 of the second engaging part 64 is engaged with the connecting hole 60d of the engaged beam 60c of head rest plate 60.Because these actions are by means of the force of torsion spring 63c and coil spring 64a, therefore, it is possible to easily carry out.
The height adjustment mechanism of above-mentioned baby safety band 70 is owing to having the second engaging part 64 relative to engaging these two engagings relative to back-rest 32 of the engaging of head rest plate 60 and the first engaging part 63, even if therefore suppose that child seat 1 entirety has all been applied in impact, also there will not be the situation that the engaging of both sides all comes off.That is, the second engaging part 64 is removed relative to the engaging of head rest plate 60 and is implemented by upper moving of direction, and the first engaging part 63 is removed by hand of rotation, the moving of direction namely left from back-rest 32 and being implemented relative to the engaging of back-rest 32.Therefore, in order to remove these engagings, the direction of required power is roughly orthogonal.
Moreover, the second engaging part 64 relative to head rest plate 60 engaging remove and the first engaging part 63 relative to back-rest 32 engaging remove be implemented by a series of continuous action that the second knob 64b of the second engaging part 64 is carried out lifting.That is, by exerting a force along identical upper direction to the second knob 64b of the second engaging part 64 all the time, thus the engaging in two stages can be removed.Therefore, the height adjustment mechanism of above-mentioned baby safety band 70 is difficult to carry out and the releasing had a mind to mode easy to implement and being formed to remove unexpectedly.
In addition, owing to making engaged curved face part 38 be formed on the central authorities of back-rest 32 while central authorities column sections 37 being retained in back-rest 32, therefore the intensity of back-rest 32 is maintained.In addition, concave curved surface due to the engaged curved face part 38 of back-rest 32 is formed to be aligned to three row along short transverse, therefore the engaging rod 65 of the first engaging part 63 is not a line, thus prevents situation about engaging from the concave curved surface of highly mutually different engaged curved face part 38.
In addition, as long as the height adjustment mechanism of baby safety band 70, i.e. travel mechanism can operate by referring to this action illustrated by Figure 21, then can at random form.Namely, as long as direction of slip is parallel with the direction applying power to the second engaging part, and first by the slip of the second engaging part, engaging is removed, then by the rotation of the first engaging part, engaging is removed, thus becoming the state that can slide, then travel mechanism can at random be formed.In addition, above-mentioned height adjustment mechanism not only can be applied to the field of child seat, also can be applied to existence and realize safely in the other field of the demand of the operation of travel mechanism.
In addition, baby safety band 70, by above-mentioned height adjustment mechanism and according to the sitting height of infant and to after highly suitably regulating, needs the bodily form according to infant and suitably regulates the degree of tightening up of baby safety band 70, the length that namely extends to the front of back-rest 32.
Be described with reference to the adjustment of Figure 23 and Figure 24 to the length of the baby safety band 70 of adjustment in use band 75.Figure 23 is the block diagram of the accommodation zone 75 of the extreme higher position representing child seat 1.Figure 24 is the block diagram of the accommodation zone 75 of the extreme lower position representing child seat 1.Figure 23 and Figure 24 is block diagram when observing the seat main body 30 of child seat 1 from below.
The baby safety band 70 of left and right is joined together at the rear side of the back-rest 32 of seat main body 30, and therefore, it is consisted of a belt.In addition, baby safety band 70 links in one end of the rear side of the back-rest 32 of seat main body 30 and the accommodation zone 75 of a wide cut.That is, one end of accommodation zone 75 is folded back, and be folded back after being partially overlapping sewn nearby.Its result is, ring portion 75a is formed on one end of accommodation zone 75.Baby safety band 70 is inserted among ring portion 75a.Therefore, the ring portion 75a of accommodation zone 75 forms the connecting part linked with baby safety band 70.Accommodation zone 75 is by usually being woven and formed, but be not limited in this by the material, the such as polyster fibre that use on the seatbelt of vehicle.
Accommodation zone 75 extends downwards along the back-rest 32 of seat main body 30, and near the bottom being formed on seat main body 30, namely the bottom of the trailing flank of the cylindrical portion 31b of seat bottom 31 opening 31c (also with reference to Fig. 7) and enter inner space 35.Next, be described with reference to Fig. 9, the accommodation zone 75 entered in the inner space 35 of seat main body 30 is bent into acute angle by the band support projection 33e outstanding be upward formed on the bottom surface of inner space 35 and extends to upward near the lower surface of seat plate 34.
Next, accommodation zone 75 in inner space 35 toward the front relative to seat bottom surface 33 after extending abreast, from be formed on seat bottom 31 cylindrical portion 31b leading flank top opening 31d (also with reference to Fig. 7) internally pass outside space 35.Then, accommodation zone 75 from be formed on seat bottom 31 frustum of a cone portion 31a leading flank opening 31e extend towards the top of seat bottom 31.Then, accommodation zone 75 via be configured in operating mechanism operator's station 55 the band adjuster 76 at rear and the front to seat main body 30 extends (Fig. 1), wherein, operating mechanism is installed in the front part office of the upper surface of seat bottom 31.
The locking with accommodation zone 75 can be removed by known mechanism with adjuster 76.If accommodation zone 75 by locking, then cannot make accommodation zone 75 move in the longitudinal direction relative to band adjuster 76 by band adjuster 76.On the other hand, if the locking of accommodation zone 75 is removed by band adjuster 76, then accommodation zone 75 can be moved in the longitudinal direction relative to band adjuster 76.
Next, the length adjustment of baby safety band 70 is described.The length adjustment of baby safety band 70 is implemented under the state of locking relieving band adjuster 76.When the extension of the baby safety band 70 for the front to back-rest 32 is extended, can by baby safety band 70 that the front to back-rest 32 is extended forwards or top carry out tractive and extended.Finally, baby safety band 70 tractive to the rear side of the back-rest 32 at seat main body 30 can not being had remainder.Now, the length of the baby safety band 70 that the front to back-rest 32 extends is maximum, and the ring portion 75a of the accommodation zone 75 linked with baby safety band 70 is at extreme higher position (Figure 23).
The extreme higher position of accommodation zone 75 is, the position that ring portion 75a is corresponding with the part that the channel opening 60a of the head rest plate 60 being inserted through baby safety band 70 is formed.Therefore, the extreme higher position of accommodation zone 75 can correspond to the pass the height adjustment mechanism of baby safety band 70 and the height after being conditioned and changing.
On the other hand, when the contraction in length of the baby safety band 70 for the front to back-rest 32 is extended, can forwards carry out tractive by the part (Fig. 1) of the accommodation zone 70 that the front to seat main body 30 is extended and make it shorten.Finally, can by accommodation zone 75 tractive near the opening 31c that the ring portion 75a of the accommodation zone 75 linked with baby safety band 70 is configured in seat bottom 31.Now, the length of the baby safety band 70 that the front to back-rest 32 extends is the shortest, and the ring portion 75a of the accommodation zone 75 linked with baby safety band 70 is at extreme lower position (Figure 24).
The extreme lower position of accommodation zone 75 is, the position of ring portion 75a near the opening 31c of seat bottom 31.Therefore, the extreme lower position of accommodation zone 75 is fixed on the position of opening 31c of seat bottom 31.
Above, the length adjustment of baby safety band 70 is carried out tractive by the part of the baby safety band 70 extended in the front to back-rest 32 or the accommodation zone 75 extended to the front of seat main body 30 and is implemented, and can regulate thus to the degree of tightening up of the baby safety band 70 corresponding with the bodily form of infant.
In child seat 1, accommodation zone 75 extends to the bottom opening 31c that is neighbouring, i.e. the bottom place of the trailing flank of the cylindrical portion 31b of seat bottom 31 of the rear side being formed on seat main body 30, then enters in inner space 35.Then, accommodation zone 75 is bent into acute angle by band support projection 33e and extends upward.Therefore, not talkative accommodation zone 75 towards band adjuster 76 via shortest distance, but around roundabout path.Therefore, in child seat 1, by near the bottom that the extreme lower position of accommodation zone 75 to be configured in compared with existing child seat seat main body 30 on the lower, thus ensure that the distance between the extreme higher position of accommodation zone 75 and extreme lower position longlyer.Its result is, the scope of the length adjustment of baby safety band 70 can be expanded further.
In addition, in order to carry out the adjustment of accommodation zone 75 swimmingly, also pulley can be configured at the top place of the part abutted with seat main body 30, such as opening 31c.In addition, accommodation zone 75 also can not via the inside of seat main body 30, but lower surface that is outside via it, i.e. seat main body 30.
In addition, on the back side of the back-rest 32 of seat main body 30, backplate (wire harness plate) 68 is installed.Figure 25 is the amplification stereogram at the back side of child seat 1, and Figure 26 is the block diagram of the backplate 68 of child seat 1.Backplate 68 plays following effect, that is, cover to make it to become the mode of obstruction the unnecessary baby safety band 70 of rear side of back-rest 32 and accommodation zone 75 that are configured in seat main body 30, and be accommodated in the back side of back-rest 32.In addition, backplate 68 plays following effect, that is, to the engaged curved face part 38 of the both sides of the opening 36 of the back-rest 32 of the part and seat main body 30 that are formed on moving part 61 not make it the mode exposed and to cover.
As shown in the longitudinal section of Fig. 9, backplate 68 seat main body 30 Width middle body with across and the mode that extends of short transverse and being configured, and be fitted and be installed on seat main body 30.Backplate 68 has plate top 68a and plate bottom 68b.Backplate 68 is in order to have flexibility and such as be utilized injection moulding and be integrally formed by the resin material of polypropylene etc.Particularly the part of the plate top 68a of backplate 68 and the boundary line of plate bottom 68b defines hinge 68c, and described hinge 68c is formed thinner compared with other parts, and can when can not damaged and alternating bending.But backplate 68 also can omit hinge 68c, and it is made to bend by its flexibility.In addition, baby safety band 70 and accommodation zone 75 are incorporated in the accommodation space 68d (Fig. 9) between seat main body 30 and backplate 68.
The upper end of backplate 68 engages with the back-rest 32 of seat main body 30, by removing this engaging, thus can centered by hinge 68c, plate top 68a be bent towards rear, to make the accommodation space 68d between seat main body 30 and backplate 68 open.That is, backplate 68 can be made to be separated with back-rest 32 locally.Such as, when regulating the remainder of the baby safety band 70 be configured in the rear side of seat main body 30 etc., the plate top 68a of backplate 68 can be made to bend and open in the mode being easy to carry out operation.
In addition, on the plate top 68a of plate 68 overleaf, opening 68e is formed with in the mode in spanning height direction, Width central portion office.The width of opening 68c is larger compared with the width of the column sections 37 of the back-rest 32 of seat main body 30.Therefore, two openings 36 of back-rest 32 expose locally via the opening 68e of backplate 68.Its result is, on the fore-and-aft direction of the back-rest 32 of seat main body 30, can guarantee aeration, can not become uncomfortable to make the infant of seat via two openings 36 of back-rest 32 and the vent openings 60g (Figure 20) of head rest plate 60.And, form opening 68e by plate 68 overleaf, thus under the state of having installed backplate 68, can operate moving part 61.That is, via the opening 68e of backplate 68, can close to the second knob 64b of the first knob 62c of rotating bearing component 62 and the second engaging part 64.
With reference to Figure 27 to Figure 29, baby safety band 70 is described.Figure 27 is the birds-eye view of a part for baby safety band 70, and Figure 28 is the lateral plan of the elongation state of the baby safety band 70 of Fig. 1, and Figure 29 is the lateral plan of the case of bending of the baby safety band 70 of Fig. 1.
Be used to the multiple tapes 71 of baby safety band 70 by the band shape of flexibility of child seat 1, such as two pieces of tapes 71a, 71b carry out overlap and formed.Each tape 71a, 71b are by usually being woven and formed by the material, the such as polyster fibre that use on the seatbelt of vehicle.Tape 71a, 71b are along the many lines extended in the longitudinal direction, be such as sewn along two line 71c.
If make baby safety band 70 bend, then, after releasing the power making it bending, can gravity be overcome and maintain case of bending.That is, if make superimposed tape 71 bend, then the radius of curvature of the tape 71a of bending inner side is less compared with the radius of curvature of the tape 71b in bending outside.By the difference of this radius of curvature, thus between the face in outside of tape 71a in opposite inner side and the face of the inner side of the tape 71b in outside can along bending circumferencial direction, such as along tape 71 length direction and extend, and then produce dislocation.Next, if discharge bending power, then in baby safety band 70, the tape 71b in the outside of having extended will attempt to turn back to original position, but the face of the inner side of the face in the outside of the tape 71a of inner side and the tape 71 in outside is engaged by friction drag.Its result is, the baby safety band 70 be out of shape, after releasing the power making it to be out of shape, will overcome gravity and maintain shape.
Therefore, even if by infant from after child seat is removed, baby safety band 70 also can overcome gravity and maintain shape owing to untiing baby safety band 70 protection people, therefore obstacle when again making infant take a seat after this can not be become.And, because tape 71a, 71b are formed by the flexible material of polyster fibre etc., even if therefore infant, protection people contact or to collide baby safety band 70 be also safe.
In addition, also when making baby safety band 70 be out of shape, to produce the mode of the dislocation between two pieces of bands 71a, 71b larger, band 71a, 71b can be sewed up loosely.In addition, baby safety band 70 can not rely on friction drag yet, and by the metal filament, metal sheet etc. that can maintain the shape after distortion internally inserted through, and shape to be maintained.In addition, can baby safety band 70 entirety be set in the above described manner to the structure that shape maintains, also its part can be set to this structure.And, also can reel in the part of the baby safety band 70 abutted with infant and there is the baby safety band cover 77 (Fig. 1) of resiliency.In the case, for baby safety band cover 77, also can be set to the above-mentioned this structure that shape is maintained.And above-mentioned baby safety band 70 not only can be applied to the field of child seat, also can be applied to exist and overcome gravity and in other field of the demand that shape maintains.
With reference to Fig. 7 and Figure 30, the installation method that baby safety band 70 is installed to seat main body 30 is described.Figure 30 is the front view of the baby safety band 70 of child seat 1.Particularly, the baby safety band 70 shown in Figure 30 is, is provided with makes the baby safety band 70 of the left and right joint portion 78 (Fig. 1) combined by combining mechanism and the baby safety band 70 being configured in the crotch band of the crotch of infant in its one end.In the installation method installed to seat main body 30, the baby safety band 70 of left and right is identical with the baby safety band 70 of crotch band.Seat bottom 31 is run through downward by the baby safety band 70 extended from the back-rest 32 of seat main body 30 and the baby safety band 70 of crotch band as mentioned above, and is fixed in the part of the below of seat main body 30.Therefore, as shown in Figure 7, as the mounting portion of installing for making baby safety band 70 run through, the construction opening 31f of the through hole as rectangle is formed in the left and right of seat bottom 31 and front portion.
In addition, the top forming the tape 71 of the baby safety band 70 run through the seat bottom 31 of seat main body 30 is folded back, and be folded back after partly overlapping mode nearby and be sewn.Its result is, defines the ring portion 72 being formed ring-type on the top of baby safety band 70.
Next, run through seat main body 30 seat bottom 31 baby safety band 70 ring portion 72 in, be inserted into columned hold-down bars 73.Hold-down bars 73 is formed by the metal of carbon steel etc., such as, be formed by being carried out cutting by the material of pole, but be not limited in this.Hold-down bars 73 is formed, larger compared with the construction opening 31f of the seat bottom 31 run through with baby safety band 70.That is, the length of columniform hold-down bars 73 is comparatively large compared with the size of the transverse direction of the construction opening 31f of rectangle, and the diameter of hold-down bars 73 is larger compared with the size of the longitudinal direction of construction opening 31f.Therefore, under the state that hold-down bars 73 is inserted in the ring portion 72 of baby safety band 70, there will not be the situation that baby safety band 70 comes off from seat main body 30.Be inserted into hold-down bars 73 in the ring portion 72 of baby safety band 70 be fitted together to by the engagement pawl 31g near the construction opening 31f that is formed on seat main body 30 by press-button type and fix.
Because baby safety band 70 is reliably fixed by being fitted together to of press-button type of hold-down bars 73, the below to seat main body 30 is therefore there will not be to hang down and form the situation of obstruction.In addition, hold-down bars 73 is only required to be bar-shaped, also can not be cylindric, namely circular cross-sectional plane.Hold-down bars 73 such as also can be formed to have the mode of the polygonal cross-sectional plane of quadrangle and hexagon etc.
By being blocked from bar-shaped material by the hold-down bars 73 of fixing baby safety band 70, thus cost of raw and processed materials and processing charges can be made to be dirt cheap.In addition, hold-down bars 73 due to structure simple, therefore also comparatively excellent in intensity.And because fixing only make it of baby safety band 70 relative to the seat main body 30 employing hold-down bars 73 is fitted together to press-button type, therefore installation exercise is also simpler and easy.
With reference to Figure 31 and Figure 32, fluffy mechanism 80 is described.Figure 31 is the block diagram on the top of child seat 1, and Figure 32 is the decomposition assembling figure of the revotating card locking mechanism 81 of the fluffy mechanism 80 of child seat 1.

The installation that is fixed relative to the column support member 85 of left and right of the both ends of fixing fluffy pillar 82.The mode that the both ends of the first movable fluffy pillar 83 periodically rotate can rotate latch for printed circuit 86 via first relative to the column support member 85 of left and right, namely can be locked on the mode on interim position of rotation and be mounted.The both ends of the second movable fluffy pillar 84 are mounted in the mode that periodically can rotate via the second rotation latch for printed circuit 87 relative to the column support member 85 of left and right.
Therefore, the first movable fluffy pillar 83 and the second movable fluffy pillar 84 as a whole, the rotation axis that transversely extends can be centered around and forwards or rear periodically rotate.Therefore, it is possible to forwards launch fluffy or rearward fold.In addition, the angle that can rotate of the first movable fluffy pillar 83 is comparatively large compared with the angle that can rotate of the second movable fluffy pillar 84, and therefore the first movable fluffy pillar 83 can forwards launch further compared with the second movable fluffy pillar 84.
First rotates latch for printed circuit 86 has the first rotary end 86a being formed circle.In addition, the second rotation latch for printed circuit 87 has the second rotary end 87a being formed the circle identical with the first rotary end 86a diameter.Column support member 85 has the rotation supporting portion 85a that the first rotary end 86a and second being formed to rotate latch for printed circuit 86 with first rotates the identical circle of the second rotary end 87a diameter of latch for printed circuit 87.In the central authorities of rotation supporting portion 85a, be formed through the groove of U-shaped and the elastic beam 85b be divided out.
The lateral surface of the elastic beam 85b of column support member 85 is configured with the first rotary end 86a of the first rotation latch for printed circuit 86, and on the medial surface of the elastic beam 85b of column support member 85, is configured with the second rotary end 87a of the second rotation latch for printed circuit 87.Elastic beam 85b and the first rotary end 86a and the second rotary end 87a by make swivel pin 88 by inserted through in respective in the heart, thus combined in the mode that can rotate.
With first to rotate the centre of gration of the first rotary end 86a of latch for printed circuit 86 circumferentially concentric, be formed with two locking recess 86b of concave curved surface shape.Equally, with second to rotate the centre of gration of the second rotary end 87a of latch for printed circuit 87 circumferentially concentric, two lockings recess (not shown) of concave curved surface shape are formed with.In addition, on the lateral surface of the rotation supporting portion 85a of opposite column support member 85, in with first rotate the centre of gration of latch for printed circuit 86 concentric circumferentially and with across and first to rotate on the corresponding position of the locking recess 86b of the rotating range of latch for printed circuit 86, be formed and multiple locking protuberance 85c (not shown) of convex surface shape that locking recess 86b engages.Equally, on the medial surface of the rotation supporting portion 85a of opposite column support member 85, in with second rotate the centre of gration of latch for printed circuit 87 concentric circumferentially and with across and second to rotate on the corresponding position of the locking recess 87b of the rotating range of latch for printed circuit 87, be formed and multiple locking protuberance 85c (not shown) of convex surface shape that locking recess 87b engages.
In order to launch or folding awning and the first movable fluffy pillar 83 is rotated a little relative to column support member 85 time, thus the locking of the locking protuberance 85c making the locking recess 86b of the first rotation latch for printed circuit 86 and column support member 85 is temporarily removed.Namely, the locking protuberance 85c of column support member 85 is configured between the adjacent latch for printed circuit 86b of the first rotation latch for printed circuit 86, and is separated a little between the first rotary end 86a of the rotation supporting portion 85a of column support member 85 and first rotation latch for printed circuit 86.In this case, by the elastic force of the elastic beam 85b of column support member 85 linked with the first the first rotary end 86a rotating latch for printed circuit 86, thus the first rotary end 86a making the rotation supporting portion 85a of column support member 85 and first rotate latch for printed circuit 86 is biased in a direction close to each other.
Next, when making the first movable fluffy pillar 83 further rotate relative to column support member 85, the locking protuberance 85c with column support member 85 adjacent in a rotational direction stably engages by the first locking recess 86b rotating latch for printed circuit 86.The force of the elastic beam 85b of column support member 85 also contributes to this stable locking.On the other hand, the first locking rotating the locking recess 86b of the latch for printed circuit 86 and locking protuberance 85c of column support member 85 is unsure state by the state removed.Therefore, when the spinning movement of the first movable fluffy pillar 83, first rotates latch for printed circuit 86 can engage and the mode stablized with the locking protuberance 85c of column support member 85 adjacent in a rotational direction to engage recess 86b, the rotation of implementation phase, the locking namely on the position of rotation of stage.
In addition, the second movable fluffy pillar 84 relative to the rotation of column support member 85 and the identical relative to the rotation of column support member 85 of the above-mentioned first movable fluffy pillar 83.Therefore, when the spinning movement of the second movable fluffy pillar 84, second rotates latch for printed circuit 87 can engage and the mode stablized with the locking protuberance 85c of column support member 85 adjacent in a rotational direction to engage recess 87b, and carries out interim rotation.
Due to above-mentioned fluffy mechanism 80 can be made to slide in the vertical direction together with head rest plate 60, regulate therefore, it is possible to carry out height according to the sitting height of the infant taken a seat with shirtsleeve operation.In addition, the locking recess 87b rotating latch for printed circuit 87 due to the first locking recess 86b and second rotating latch for printed circuit 86 is formed concave curved surface shape, and the locking protuberance 85c of the column support member 85 engaged with these positions is formed convex surface shape, therefore, it is possible to carry out very swimmingly engaging and removing.Therefore, although have employed the structure be made up of the less simple mechanism of component count, the revotating card locking mechanism that can rotate swimmingly under the condition not needing lubricating oil and engage can also be realized.
In addition, the structure of any one party in omission two the first movable fluffy pillars 83 and the second movable fluffy pillar 84 can also be adopted.Thus, when making child seat product, the difference of often kind of product model can be shown simply.In addition, the locking recess 86b and second that also locking protuberance can be formed in the first rotation latch for printed circuit 86 rotates on latch for printed circuit 87, and is formed on column support member 85 by locking recess.In addition, the quantity engaging protuberance and locking recess can at random be selected.And locking protuberance and locking recess can be arbitrary shape in the scope that can realize its locking and releasing.
Be described with reference to the detent mechanism 110 of Figure 33 to Figure 35 to supporting leg 100.Figure 33 is the block diagram of the detent mechanism 110 of the support foot 100 of child seat 1, and Figure 34 is the longitudinal section kept left compared with the central authorities of the detent mechanism 110 of Figure 33, and Figure 35 is the longitudinal section of the central authorities of detent mechanism through Figure 33.In addition, Figure 33 is in order to make the inside of detent mechanism 110 clear and definite, thus the parts of a part are only depicted profile.
As shown in FIG. 2 and 3, supporting leg 100 extends in the floor to the vehicle that the seat of the vehicle being provided with child seat main body 10 supports, and supports child seat main body 10, the i.e. forward portion of bearing block 20 from below.Supporting leg 100 has: retractile foot 101 and be installed in the detent mechanism 110 determined in foot 101 and to the length of foot 101 along its length.
Foot 101 has: be installed in the first cartridge 102 in bearing block 20, and is configured in second cartridge 103 of below of the first cartridge 102.The top of the second cartridge 103 is inserted in the bottom of the first cartridge 102, and can regulate the length of foot 101 by regulating insertion.The through hole 102a that fixed parts 117 described later is inserted into is formed on the first cartridge 102.In addition, to be configured along its length and be optionally the inserted into multiple through hole 103a of fixed parts 117 are formed on the second cartridge 103 (Fig. 2).
Detent mechanism 110 has: housing 113, and it is installed in the bottom place of the first cartridge 102, and possesses the first housing halves 111 and second housing halfbody 112; Slide block 114; Foot's joystick 115.First housing halves 111 is mounted from the front of the first cartridge 102, and second housing halfbody 112 is mounted from the rear of the first cartridge 102.That is, the first housing halves 111 and second housing halfbody 112 are fitted together in the mode clamped the first cartridge 102 from front and back, and are mounted relative to the first cartridge 102.
In the housing 113 of the first housing halves 111 side, with on the direction vertical with the length direction of foot 101, namely relative to the foot 101 of running through in housing 113 away from direction and close direction between can carry out the mode of sliding, be configured with slide block 114.That is, in the housing 113 of the first housing halves 111 side, the multiple guiding wall 111a for guiding the slip of slide block 114 are formed.The inwall 111b of the front surface of the first housing halves 111 is formed the protuberance 111c of rearward outstanding hollow, and is configured with coil spring 116 around protuberance 111c.
The recess 114a that protuberance 111c and the coil spring 116 of the first housing halves 111 are received is formed at the top place of slide block 114.In addition, in the recess 114a of slide block 114, be formed with the guide protrusion 114b (Figure 35) of forwards outstanding column.That is, the protuberance 111c of the first housing halves 111 and coil spring 116 receive in recess 114a at an upper portion thereof by slide block 114, and the guide protrusion 114b of slide block 114 is inserted in the protuberance 111c of hollow.In addition, projection 114c (Figure 34) is formed with in the left and right on the top of slide block 114.And, at the bottom place of slide block 114, be formed with the fixed parts 117 (Figure 35) of rearward outstanding split.Fixed parts 117 also can form with slide block 114.
On one end of foot's joystick 115, as be configured in housing outside operating portion and be formed with operation corbel back slab 115a, and on the other end of foot's joystick 115, be formed with the inside that is configured in housing 113 and a pair connecting part 115b linked with the projection 114c of the left and right of slide block 114.Each connecting part 115b is formed with elongated hole 115c, and in elongated hole 115c, is configured with the projection 114c of corresponding slide block 114.Cylindric swivel bearing projection 115d is formed respectively in the left and right of the pars intermedia of foot's joystick 115.Foot's joystick 115 is installed in housing 113 by utilizing the swivel bearing projection 115d of left and right, thus can be centered around the rotation axis that transversely extends and rotate.
Under the state being arranged in foot 101 by detent mechanism 110, the direction of slide block 114 by coil spring 116 to foot 101 is biased.Therefore, fixed parts 117 is inserted in the through hole 102a of the first cartridge 102 and through hole 103a of any one of the second cartridge 103, thus the second cartridge 103 is limited relative to the slip of the first cartridge 102.In addition, the first cartridge 102 and the second cartridge 103 and fixed parts 117 are formed by the metal of carbon steel etc., but are not limited in this.
When regulating the length of foot 101, first in the mode lifted upward by the operation corbel back slab 115a of foot's joystick 115, namely operated by upward direction, and the rotation axis made it around swivel bearing projection 115d rotates.This action is carried out in the following way, such as by holding the first cartridge 102 of the top of detent mechanism 110 with the right hand stretched out downward from top, and by the thumb of its right hand, operation corbel back slab 115a hooked from down and lift upward.And make the action that the operation corbel back slab 115a of foot's joystick 115 rotates if proceed, then by rotary motion, the direction to foot 101 is moved by operation corbel back slab 115a.
With the rotary motion of such operation corbel back slab 115a, the connecting part 115b of the other end of foot's joystick 115 is rotated to the direction left from foot 101.By the rotary motion of connecting part 115b, thus slide block 114 slides to the direction left from foot 101 along guiding wall 111a.That is, the connecting part 115b of foot's joystick 115 is rotated, and on the other hand, the movement of slide block 114 is limited on direction of slip by guiding wall 111a.But, the projection 114c of the left and right of slide block 114 is moved in elongated hole 115c by the position of rotation according to corresponding connecting part 115b, thus the rotary motion of connecting part 115b can not be hindered, and the rotary motion of connecting part 115b can be converted to the sliding motion of slide block 114.In other words, the conversion of moving with this can be determined the shape of the elongated hole 115c of connecting part 115b by the mode of carrying out swimmingly.

In addition, according to the present invention, in the child seat 1 of seatbelt type and the child seat 200 of ISOFIX type, increase change separately all than being easier to.Such as, only need prepare the height of correct backup plate 60 can carry out the seat main body 30 regulated and the seat main body 30 being fixed with head rest plate 60, just can combine the child seat 1 of seatbelt type and the child seat 200 of ISOFIX type in respective seat main body 30, and easily can obtain total four kinds change.In the same way, by the radical etc. of the presence or absence of fluffy mechanism 80 or the movable fluffy pillar of fluffy mechanism 80, also change can be increased further.
Child seat involved by above-mentioned embodiment is the type with leaning device and rotating mechanism, but, also can apply the present invention to not have in the child seat of one party in leaning device and rotating mechanism or both sides.In addition, the rise part 222 of the bearing block 220 of the second embodiment is owing to there is no need for space and the intensity of configuration locking device 130, therefore, compared with the rise part 22 of the bearing block 20 of the first embodiment, the width of the transverse direction of all right constriction rise part 222 or the height of reduction rise part 222.And, by configuration locking device 130 in the bearing block 220 of the second embodiment, thus the child seat of the feature of the both sides with seatbelt type and ISOFIX type can be obtained.
In addition, although be suitably referred to the material of main parts, and the material of silent parts is formed mainly through being undertaken one-body molded by the resin material of polypropylene or polyacetal etc.But, also can adopt other material or manufacture method.
Although according to specific embodiment to invention has been detailed description, but as those skilled in the art, various change, correction etc. can be carried out under the condition not departing from claims of the present invention and technological thought.
