在车辆安全技术领域中，车辆安全带可以是用于在车辆出现紧急状况例如紧急刹车、碰撞或者倾翻时保护乘员的安全保护装置，其中，通过带状的织带可以束缚乘员，织带可以通过安全带卷收器的芯轴卷收，并且可以通过锁舌固定于车辆。车辆安全带可以是车辆被动安全***中的重要组成部分。车辆例如可以是乘用车、货车或者其他的交通工具。In the field of vehicle safety technology, a vehicle seat belt may be a safety protection device for protecting an occupant when the vehicle encounters an emergency situation such as emergency braking, collision or overturn, wherein the occupant can be restrained by a belt-shaped webbing, and the webbing can pass the safety The mandrel with retractor is retracted and can be secured to the vehicle by means of a locking tongue. Vehicle seat belts can be an important part of a vehicle's passive safety system. The vehicle may be, for example, a passenger car, a van or other means of transport.
随着车辆技术的发展，用户对车辆舒适性的要求越来越高，对于车辆座椅的舒适性的要求同样如此。在车辆座椅的发展中，座椅靠背的倾角已从固定不变演变为可调，而且可调角度越来越大。在一些商务车上甚至已经实现了座椅靠背的接***躺的调整角度。With the development of vehicle technology, users have higher and higher requirements for vehicle comfort, and the same is true for the comfort of vehicle seats. In the development of vehicle seats, the inclination angle of the seat back has evolved from fixed to adjustable, and the adjustable angle has become larger and larger. In some commercial vehicles, the adjustment angle of the seat back close to flat has even been achieved.
一些已知的安全带卷收器配备车感装置，该车感装置可以作为安全带卷收器中的机械传感器来感知车辆状态，例如可以感知车辆的加速度和倾斜角度，其中，当车辆发生紧急状态时，车感装置可以感知该紧急状态，并且可以促使安全带卷收器的芯轴锁止，阻止织带继续从芯轴抽出，使得乘员可以被织带良好地束缚并且从而获得良好的安全保护。典型地，较早的车感装置固定地安装在车身或者车辆座椅上，这有可能不满足座椅靠背可调的技术要求。Some known seat belt retractors are equipped with a vehicle sensing device, which can be used as a mechanical sensor in the seat belt retractor to sense vehicle status, such as the acceleration and inclination angle of the vehicle. In this state, the vehicle sensing device can sense the emergency state, and can prompt the mandrel of the seat belt retractor to lock, preventing the webbing from continuing to be drawn out of the mandrel, so that the occupant can be well restrained by the webbing and thus obtain good safety protection. Typically, earlier vehicle feeling devices are fixedly mounted on the vehicle body or vehicle seat, which may not meet the technical requirements of seat back adjustment.
另外已知自适应的车感装置，其能靠自身重力随着座椅靠背一起调节。由于自适应的车感装置是活动的，其自适应角度调节范围是有限的，并且车感灵敏度尚有改进的空间。关于车感装置和锁止装置，例如可参考本申请人的专利申请CN110027502A。In addition, adaptive car-sensing devices are known, which can be adjusted together with the seat back by their own weight. Since the adaptive car-sensing device is active, its adaptive angle adjustment range is limited, and there is still room for improvement in the car-sensing sensitivity. Regarding the vehicle sensing device and the locking device, for example, reference may be made to the applicant's patent application CN110027502A.
此外，由专利文献CN102991452B已知一种用于车感装置的调角盘组件，其具有调角盘，该调角盘具有长径部和短径部，在长径部与短径部的连接处形成平面部，该平面部用于安装芯线收紧机构，芯线端部固定在短径部并经过平面部延伸至长径部，其中，芯线能沿着长径部的外缘卷绕。在芯线的装配过程中，需要将芯线绕过调角盘的长径部，切入到调角壳体的长径部中，并且然后引出。在芯线的装配过程，芯线始终处于紧密配合，这使得芯线的装配难度较大。整个调角盘布局不够紧凑，外形尺寸 较大，这不便于客户安装和匹配。In addition, patent document CN102991452B discloses a steering wheel assembly for a vehicle feel device, which has a steering wheel, the steering wheel has a long-diameter portion and a short-diameter portion, and the long-diameter portion and the short-diameter portion are connected at the connection A flat part is formed at the junction, the flat part is used to install the core wire tightening mechanism, the end of the core wire is fixed on the short diameter part and extends to the long diameter part through the flat part, wherein the core wire can be rolled along the outer edge of the long diameter part around. In the assembling process of the core wire, the core wire needs to bypass the long diameter part of the angle adjustment disc, cut into the long diameter part of the angle adjustment shell, and then lead out. During the assembly process of the core wire, the core wire is always in a close fit, which makes the assembly of the core wire more difficult. The layout of the entire angle adjustment plate is not compact enough, and the external dimensions are large, which is not convenient for customers to install and match.

具体实施方式detailed description
图1示意性地显示具有安全带卷收器的车辆座椅的侧视图。图2是图1的安全带 卷收器的放大的示意图，其中，车辆座椅被隐去。车辆例如可以是乘用车或载货车，特别是部分自主驾驶的或者完全自主驾驶的机动车。所述车辆座椅具有座部5和靠背4，所述靠背4可以从预定的在图1中用实线描述的基本上直立的初始位置向前和向后调节倾角。所述初始位置对于乘员就座和操纵车辆可以是优化的。所述靠背4可以向前放倒在座部5上，以便腾出空间。所述靠背4可以向后调节至接近水平的最大倾角位置，在该最大倾角位置上，乘员可以休息。参考车辆的前进方向，最大倾角位置可以对应于接近180°的倾角，例如大约170°的倾角。所述靠背4可以根据用户的需要调节至预定的初始位置与最大倾角位置之间的任意的中间位置，例如可以调节至大约120°或者135°的倾角。靠背4的两个末端位置在图1中用虚线描述。Figure 1 schematically shows a side view of a vehicle seat with a seat belt retractor. Figure 2 is an enlarged schematic view of the seat belt retractor of Figure 1 with the vehicle seat hidden. The vehicle can be, for example, a passenger car or a truck, in particular a partially or fully autonomous motor vehicle. The vehicle seat has a seat portion 5 and a backrest 4 which can be reclined forwards and backwards from a predetermined substantially upright initial position depicted in solid lines in FIG. 1 . The initial position may be optimized for occupant seating and maneuvering of the vehicle. The backrest 4 can be laid forward on the seat 5 in order to make room. The backrest 4 can be adjusted rearwardly to a near-horizontal maximum inclination position where the occupant can rest. The maximum inclination position may correspond to an inclination angle of approximately 180°, for example, an inclination angle of approximately 170°, with reference to the heading direction of the vehicle. The backrest 4 can be adjusted to any intermediate position between the predetermined initial position and the maximum inclination angle position according to the needs of the user, for example, it can be adjusted to an inclination angle of about 120° or 135°. The two end positions of the backrest 4 are depicted by dashed lines in FIG. 1 .
卷收器主体1固定地安装在靠背4中。卷收器主体1具有集成的可转动的车感装置10(见图2和图3)。在靠背4的枢轴上可以同轴地安装调角盘组件3，该调角盘组件经由芯线组件2与车感装置10耦合。在靠背4的预定的初始位置上，车感装置10处于基本上竖直定向中。在车感装置相对于靠背固定不动的情况下，在靠背从初始位置向后调整一定角度时，车感装置相应地以该角度偏离竖直定向。在自适应的车感装置的情况下，在靠背从初始位置向后调整一定角度时，车感装置依靠自身重力自适应地转动并且保持在竖直定向中，然而活动的车感装置在灵敏度方面具有改进的空间，并且自适应调节的角度范围典型地不超过45°。在本发明的安全带卷收器中，在靠背4从初始位置向后调整一定角度时，这一方面导致车感装置10相应地以该角度偏离竖直定向，另一方面同时导致调角盘组件3对芯线组件2的牵拉并且最终导致车感装置10在相反方向上以另一个角度转动，所述另一个角度可以至少部分地补偿前述的角度，尤其优选基本上完全补偿前述的角度并且从而使得车感装置10可以基本上保持在竖直定向中。由于车感装置10的活动性受到调角盘组件3和芯线组件2约束，车感灵敏度甚至可以与固定不动地安装的车感装置相比较。与此同时，车感装置在定位角度方面可以与自适应的车感装置相比较。换言之，按本发明的车感装置可以兼具固定安装的车感装置的优点和自适应的车感装置的优点。The retractor body 1 is fixedly mounted in the backrest 4 . The retractor body 1 has an integrated rotatable feel device 10 (see FIGS. 2 and 3 ). On the pivot shaft of the backrest 4 , a reclining disc assembly 3 can be coaxially mounted, and the reclining disc assembly is coupled with the vehicle feeling device 10 via the core wire assembly 2 . In the predetermined initial position of the backrest 4 , the sensor device 10 is in a substantially vertical orientation. In the case where the vehicle sensing device is fixed relative to the backrest, when the backrest is adjusted backwards by a certain angle from the initial position, the vehicle sensing device accordingly deviates from the vertical orientation by this angle. In the case of an adaptive car-sensing device, when the backrest is adjusted backwards by a certain angle from its initial position, the car-sensing device is adaptively rotated by its own gravity and remains in a vertical orientation, whereas an active car-sensing device is sensitive in terms of sensitivity There is room for improvement, and the angular range of adaptive adjustment typically does not exceed 45°. In the seat belt retractor according to the invention, when the backrest 4 is adjusted rearwards by a certain angle from the initial position, on the one hand, the vehicle sensor device 10 is accordingly deviated from the vertical orientation by this angle, and on the other hand, at the same time, the angle adjustment disk is caused. The pulling of the core wire assembly 2 by the assembly 3 and finally the rotation of the vehicle feel device 10 in the opposite direction by another angle which can at least partially compensate the aforementioned angle, especially preferably substantially completely compensate the aforementioned angle And so that the vehicle sensing device 10 can remain substantially in a vertical orientation. Since the mobility of the vehicle feeling device 10 is constrained by the cam plate assembly 3 and the core wire assembly 2, the vehicle feeling sensitivity can even be compared with that of a fixedly installed vehicle feeling device. At the same time, the car-sensing device can be compared with the adaptive car-sensing device in terms of positioning angle. In other words, the vehicle-sensing device according to the invention can combine the advantages of a fixed-mounted vehicle-sensing device with the advantages of an adaptive vehicle-sensing device.
如图2和图3所示，卷收器主体1可以包括框架17。典型地，框架17可以构成为U形框架。用于卷绕织带的芯轴26可转动地支撑在框架17中，并且可以在一个轴向端部上配备使芯轴在卷收方向上预紧的卷簧和遮盖该卷簧的卷簧侧盖，该卷簧侧盖可以固定在框架17上。卷簧和卷簧侧盖可以构成一个卷簧组件22。该芯轴26在另一个轴向端部上可以带动棘轮21。在此，卷收器主体1可以具有机械内盖18和机械外 盖23。棘轮21可以接纳在机械内盖18中，并且车感装置10可以安装在机械内盖中。机械内盖18又可以接纳在机械外盖23中。机械内盖18和机械外盖23可以共同地固定在框架17上。在车辆出现紧急状况例如发生碰撞或倾翻时，车感装置10可以锁止棘轮21，从而导致被棘轮引导的锁止爪接合到框架17的如在图3中可见的齿圈中，使得芯轴26被锁止。关于车感装置10和锁止装置，例如可以参考本申请人的专利申请CN110027502A。所述车感装置10可以包括可转动地支承的敏感座14，所述敏感座可以具有凹形的碗面。敏感球25能在敏感座中运动。在静止状态下，敏感球处于碗面的底部。在车辆出现紧急状况时，敏感球25在惯性力作用下离开碗面的底部，抬升敏感爪15，该敏感爪又抬升锁止爪8，使得锁止爪8与棘轮21接合，从而引起芯轴26的锁止。As shown in FIGS. 2 and 3 , the retractor body 1 may include a frame 17 . Typically, the frame 17 may be constructed as a U-shaped frame. The mandrel 26 for winding the webbing is rotatably supported in the frame 17 and can be provided on one axial end with a coil spring for pretensioning the mandrel in the winding direction and a coil spring side covering the coil spring Cover, the coil spring side cover can be fixed on the frame 17. The coil spring and the coil spring side cover may constitute a coil spring assembly 22 . At the other axial end, the mandrel 26 can drive the ratchet wheel 21 . Here, the retractor body 1 may have a mechanical inner cover 18 and a mechanical outer cover 23. The ratchet 21 may be received in the inner mechanical cover 18, and the feel device 10 may be installed in the inner mechanical cover. The inner mechanical cover 18 can in turn be received in the outer mechanical cover 23 . The mechanical inner cover 18 and the mechanical outer cover 23 may be fixed to the frame 17 together. In the event of an emergency situation of the vehicle, such as a collision or rollover, the vehicle sensing device 10 can lock the ratchet wheel 21 , thereby causing the locking pawl guided by the ratchet wheel to engage in the ring gear of the frame 17 as can be seen in FIG. 3 , so that the core The shaft 26 is locked. Regarding the vehicle sensing device 10 and the locking device, for example, the applicant's patent application CN110027502A can be referred to. The vehicle feel device 10 may include a rotatably supported sensitive seat 14, which may have a concave bowl surface. The sensitive ball 25 can move in the sensitive seat. At rest, the sensitive ball is at the bottom of the bowl surface. In the event of an emergency in the vehicle, the sensitive ball 25 leaves the bottom of the bowl surface under the action of inertial force, and lifts the sensitive pawl 15, which in turn lifts the locking pawl 8, so that the locking pawl 8 engages with the ratchet 21, thereby causing the spindle 26 lock.
下面参考图4至图7更详细地说明调角盘组件3以及与之关联的芯线组件2和传动箱组件9。图4是调角盘组件3的分解图，其中，芯线组件2的与调角盘组件3关联的一个区段被附加地描述。图5是调角盘组件3的调角盘31的透视图。图6是调角盘组件3的壳体部件13的透视图。图7是调角盘组件3连同芯线组件2在一种工作状态下的示意图，其中，芯线组件2的与调角盘组件3关联的一个区段被附加地描述，并且省略了芯线28的护套。The cam plate assembly 3 and its associated core wire assembly 2 and gearbox assembly 9 are described in more detail below with reference to FIGS. 4 to 7 . Figure 4 is an exploded view of the cam plate assembly 3 in which a section of the core wire assembly 2 associated with the cam plate assembly 3 is additionally depicted. FIG. 5 is a perspective view of the cam plate 31 of the cam plate assembly 3 . FIG. 6 is a perspective view of the housing part 13 of the cam plate assembly 3 . FIG. 7 is a schematic view of the angled disc assembly 3 together with the core wire assembly 2 in an operating state, wherein a section of the core wire assembly 2 associated with the angled disc assembly 3 is additionally described and the core wire is omitted 28 jacket.
调角盘组件3构造成用于，在座椅靠背调节倾角时，自动地调节车感装置10的定位角度，理想地，使得车感装置10可以基本上保持在竖直定向中。另外也可能的是，调角盘组件3可以仅部分地补偿车感装置10的由于座椅靠背调节倾角引起的与竖直方向的角度偏差。例如，当座椅靠背从直立位置向后倾斜调整20°或者说调整至相对于车辆前进方向大约110°的倾角时，调角盘组件3可以仅补偿车感装置10的与竖直方向的20°的角度偏差的一半，从而车感装置10与竖直方向仍具有10°的角度偏差。这与在车感装置10固定安装并且从而存在20°角度偏差的情况相比仍然改进车感功能。The recliner assembly 3 is configured to automatically adjust the positioning angle of the feel device 10 as the seat back is reclined, ideally, so that the feel device 10 can remain substantially in a vertical orientation. It is also possible that the camber assembly 3 can only partially compensate for the angular deviation from the vertical direction of the vehicle feel device 10 due to the seat back adjustment reclining angle. For example, when the seat back is adjusted backward by 20° from the upright position or adjusted to an inclination angle of about 110° with respect to the forward direction of the vehicle, the cam wheel assembly 3 may only compensate for the 20° angle of the vehicle feel device 10 from the vertical direction. The angle deviation of ° is half, so that the vehicle sensing device 10 still has an angular deviation of 10° from the vertical direction. This still improves the feel function compared to the case where the feel device 10 is fixedly installed and thus there is an angular deviation of 20°.
调角盘组件3包括壳体。具体地，该壳体可以包括盒状的壳体部件13和盖板11，其中，盖板11可以固定地安装至靠背4，并且壳体部件13可以与盖板11固定连接。所述壳体构造成用于与靠背4的枢轴传动连接。有利的是，所述壳体可以构造成用于与靠背4的枢轴同轴地固定地连接。因此，当靠背4围绕枢轴转动以调节倾角时，壳体随同靠背一起同步地转动。这在结构上可以是特别简单的。然而例如也可能的是，壳体借助于传动机构与靠背4的枢轴传动连接，例如可以借助于行星齿轮机构与靠背 4的枢轴同心地传动连接，其中，太阳轮可以是固定不动的，例如与座部5固定，行星架和齿圈之一可以与靠背4的枢轴固定地连接，而行星架和齿圈之中的另一个可以与壳体部件13连接。所述壳体部件13可以具有芯线引入部46，芯线组件2的芯线28可以从芯线引入部46引入到壳体中并且以端部29固定在下面还将进一步说明的调角盘31的芯线固定部58上。例如借助于螺钉32进行固定。所述壳体部件13可以具有转动半径较长的长径部41和转动半径较短的短径部42。壳体可以在第一转动方向D1上和在与第一转动方向相反的第二转动方向D2上转动，其中，第一转动方向D1对应于靠背倾角向后调整方向，第二转动方向D2对应于靠背倾角向前调整方向。The cam plate assembly 3 includes a housing. In particular, the housing can comprise a box-shaped housing part 13 and a cover plate 11 , wherein the cover plate 11 can be fixedly mounted to the backrest 4 and the housing part 13 can be fixedly connected with the cover plate 11 . The housing is configured for a pivotal drive connection with the backrest 4 . Advantageously, the housing can be configured for a fixed connection coaxially with the pivot axis of the backrest 4 . Therefore, when the backrest 4 is rotated about the pivot to adjust the inclination angle, the housing rotates synchronously with the backrest. This can be particularly simple in structure. However, it is also possible, for example, for the housing to be drive-connected to the pivot of the backrest 4 by means of a gear mechanism, for example by means of a planetary gear, to the pivot of the backrest 4 concentrically, wherein the sun gear can be stationary. One of the planet carrier and the ring gear can be fixedly connected to the pivot of the backrest 4 , for example fixed to the seat 5 , while the other of the planet carrier and the ring gear can be connected to the housing part 13 . The housing part 13 can have a core wire lead-in 46 from which the core wire 28 of the core wire assembly 2 can be introduced into the housing and fastened with the end 29 to an angle adjustment disk, which will be described further below. 31 on the core wire fixing portion 58. The fixing takes place, for example, by means of screws 32 . The housing member 13 may have a long-diameter portion 41 with a longer rotational radius and a short-diameter portion 42 with a short rotational radius. The housing can be rotated in a first rotation direction D1 and in a second rotation direction D2 opposite to the first rotation direction, wherein the first rotation direction D1 corresponds to the backward adjustment direction of the backrest inclination angle, and the second rotation direction D2 corresponds to The inclination of the backrest is adjusted forward.
所述调角盘组件3可以包括调角盘31，所述调角盘接纳在壳体中，所述调角盘能相对于壳体转动。为此，壳体部件13可以具有安装轴47，所述调角盘31可转动地安装在所述安装轴47上。所述调角盘31可以具有转动半径较长的长径部51和转动半径较短的短径部52。所述长径部51可以具有芯线固定部58。所述短径部52可以具有芯线卷绕部59。有利的是，所述芯线卷绕部59可以构成为所述短径部52的周缘的周向槽，优选周向槽的深度和宽度不小于芯线28的直径。The cam disc assembly 3 may include a cam disc 31 that is received in the housing, the cam disc being rotatable relative to the housing.

Referring to the first rotational direction, the chute has a front end 56 and a rear end 57 . The function of the chute 55 will be described in more detail later.
在最简单的情况下，芯线组件2可以仅包括芯线28。然而有利的是，芯线组件2可以附加地包括护套27。所述护套27的朝向调角盘组件3的端部可以固定在壳体的芯线引入部46中。芯线引入部46可以通向壳体部件13的短径部42，并且短径部42可以具有芯线入口45，芯线28可以穿过芯线入口45到达壳体内部并且切向地引向芯线卷绕部59。芯线28的另一个端部30可以与车感装置10传动连接，使得芯线28在调角盘13上的卷绕和退绕可以操纵车感装置10。更具体地，芯线28的端部30可以与车感装置10的活动的敏感座14传动连接。In the simplest case, the core wire assembly 2 may comprise only the core wire 28 . Advantageously, however, the core wire assembly 2 can additionally comprise a sheath 27 . The end of the sheath 27 facing the angled disc assembly 3 can be fixed in the core wire lead-in 46 of the housing.

图7是调角盘组件3连同芯线组件2在一种工作状态下的示意图，在该工作状态下，车辆座椅的靠背4已经从基本上直立的初始位置向后调整一定角度，壳体部件13 已经在第一转动方向D1上转动，芯线28已经缠绕芯线卷绕部59的一段。挡块6与滑槽55的后端部54贴靠，调角盘31被扳手12固定不动。壳体部件13可以从如图7所示位置沿着第一转动方向D1继续转动，换言之，车辆座椅的靠背4可以继续朝后调整倾角，与此同时，芯线28可以继续在芯线卷绕部59上卷绕。FIG. 7 is a schematic view of the reclining plate assembly 3 together with the core wire assembly 2 in a working state, in which the backrest 4 of the vehicle seat has been adjusted rearward by a certain angle from the substantially upright initial position, and the housing The part 13 has been rotated in the first rotational direction D1 and the core wire 28 has been wound around a section of the core wire winding portion 59 . The stopper 6 is in contact with the rear end 54 of the chute 55 , and the angle adjustment plate 31 is fixed by the wrench 12 . The housing part 13 can continue to rotate along the first rotation direction D1 from the position shown in FIG. 7 , in other words, the backrest 4 of the vehicle seat can continue to be reclined toward the rear, and at the same time, the core wire 28 can continue to be wound on the core wire. It is wound around the winding portion 59 .
上述的运动过程也可以根据运动相对性以车辆座椅的靠背4为参照系如下地描述。在车辆座椅的靠背从基本上直立的初始位置向后调整时，与靠背4固定的壳体部件13是固定不动的，与座部5固定的扳手12在第二转动方向D2上转动，由于扳手12的挡块6挡靠在滑槽55的端部57上，扳手12带动调角盘31一起转动，使得芯线28被卷绕到芯线卷绕部59上。传动滑轮19相应地转动，芯线28在传动滑轮19上退绕，传动滑轮19借助推动杆来推动车感装置10，使得车感装置10发生转动。The above-mentioned movement process can also be described as follows with reference to the backrest 4 of the vehicle seat according to the movement relativity. During the rearward adjustment of the backrest of the vehicle seat from the substantially upright initial position, the housing part 13 fixed to the backrest 4 is stationary, the wrench 12 fixed to the seat 5 is rotated in the second rotational direction D2, Since the stop 6 of the wrench 12 is against the end 57 of the chute 55 , the wrench 12 drives the angle adjustment plate 31 to rotate together, so that the core wire 28 is wound on the core wire winding portion 59 . The transmission pulley 19 rotates accordingly, the core wire 28 is unwound on the transmission pulley 19, and the transmission pulley 19 pushes the vehicle sensing device 10 by means of a push rod, so that the vehicle sensing device 10 rotates.
下面继续参照车辆坐标系来描述调角盘组件3的其他工作过程。The following continues to describe other working processes of the cam wheel assembly 3 with reference to the vehicle coordinate system.
如果从如图7所示位置出发，车辆座椅的靠背4朝直立的初始位置返回，则壳体部件13在第二转动方向D2上转动，调角盘31在芯线28被预紧的情况下以滑槽55的后端部57保持压靠在挡块6上，芯线28从芯线卷绕部59上退绕。当壳体部件13沿着第二转动方向D2继续转动直至壳体部件13的短径部42的后端面44接触调角盘31的长径部的前端面53时，调角盘31与壳体部件13一起运动，其中，滑槽55的存在允许调角盘31与壳体部件13一起运动，它们可以一起运动直至滑槽55的前端部56到达挡块6。调角盘31与壳体部件13的一起运动可以对应于车辆座椅的靠背4的朝前放倒过程，其中，车感装置10借助于调角盘组件3的角度调节是不需要的。If, starting from the position shown in FIG. 7 , the backrest 4 of the vehicle seat is returned to the upright initial position, the housing part 13 is rotated in the second rotational direction D2 , and the cam plate 31 is preloaded with the core wire 28 . Next, the rear end portion 57 of the chute 55 is kept pressed against the stopper 6 , and the core wire 28 is unwound from the core wire winding portion 59 . When the housing member 13 continues to rotate along the second rotation direction D2 until the rear end surface 44 of the short-diameter portion 42 of the housing member 13 contacts the front end surface 53 of the long-diameter portion of the cam plate 31, the cam plate 31 and the housing The part 13 moves together, wherein the presence of the slideway 55 allows the cam plate 31 to move together with the housing part 13 , which can move together until the front end 56 of the slideway 55 reaches the stop 6 . The movement of the cam plate 31 together with the housing part 13 can correspond to a forward tilting process of the backrest 4 of the vehicle seat, wherein the angle adjustment of the vehicle feel device 10 by means of the cam plate assembly 3 is not required.
当车辆座椅的靠背4从朝前放倒在座部5上的位置出发返回到直立的初始位置时，壳体部件13在第一转动方向D1上转动，调角盘31被预紧的芯线28牵拉并且从而与壳体部件13一起在第一转动方向D1上转动，直至滑槽55的后端部57到达挡块6并且从而调角盘31被扳手12和扳手滑块7固定不动。接着，在壳体部件13在第一转动方向D1上继续转动时，芯线28在芯线卷绕部59上卷绕并且因此发挥角度调节功能。如果所涉及的车辆座椅的靠背4不具有朝前放倒的功能，而仅具有朝后调整倾角的功能，那么滑槽55可以被取消，扳手12与调角盘31可以直接地固定连接。When the backrest 4 of the vehicle seat is returned to the upright initial position from the forwardly reclined position on the seat 5, the housing part 13 is rotated in the first rotational direction D1, and the cam plate 31 is preloaded by the core wire. 28 is pulled and thus rotated together with the housing part 13 in the first rotational direction D1 until the rear end 57 of the slideway 55 reaches the stop 6 and thus the cam plate 31 is immobilized by the spanner 12 and spanner slide 7 . Then, when the housing part 13 continues to rotate in the first rotational direction D1 , the core wire 28 is wound on the core wire winding portion 59 and thus performs an angle adjustment function. If the backrest 4 of the vehicle seat concerned does not have the function of tilting forward, but only has the function of adjusting the inclination angle backward, the sliding groove 55 can be eliminated, and the wrench 12 and the angle adjustment plate 31 can be directly and fixedly connected.
在本公开的设计方案中，在一些实施方式中可能的是，在芯线的装配过程中，芯线可以绕过调角盘的短径部，切入到调角组件的壳体部件的短径部，并且然后引出。由于壳体部件的短径部可以相对较短，在装配过程中在芯线的两侧可以存在结构空腔，从而可以较容易地将芯线从壳体部件的短径部引出。整个调角盘布局可以是紧凑 的，外形尺寸可以是较小的，这可以便于客户安装和匹配。In the design solution of the present disclosure, in some embodiments, it is possible that during the assembly process of the core wire, the core wire can bypass the short diameter part of the angle adjustment disc and cut into the short diameter of the housing part of the angle adjustment assembly part, and then lead out. Since the short diameter portion of the housing part may be relatively short, structural cavities may exist on both sides of the core wire during the assembly process, so that the core wire can be drawn out from the short diameter part of the housing part more easily. The entire cam layout can be compact, and the overall dimensions can be smaller, which can facilitate customer installation and matching.
