图1为本发明的实施例提供的一种座椅安全带加热组件的安全带带体结构示意图；图2为本发明的实施例提供的一种座椅安全带加热组件的电路原理图；图3为本发明的实施例提供的一种座椅安全带加热组件的加热组件两侧均与安全带带体连接时的结构图；图4为本发明的实施例提供的一种座椅安全带加热组件的加热组件单侧与安全带带体连接时的结构图；图5为本发明的实施例提供的一种座椅安全带加热组件的电阻式加热带结构示意图，需要说明的是，在图5中经线中连续线表示导体材质线，也即导体经线71；经线中间断线表示绝缘材质线，也即绝缘经线72；纬线中较细的线表示绝缘材质线，也即绝缘纬线81；纬线中较粗的线表示导体材质线，也即导体纬线82，其中导体经线71作为电阻式加热带的发热体，且为清楚表示结构并没有示出交错编织的关系，经线纬线比较稀疏；图6为本发明的实施例提供的一种座椅安全带加热组件的电阻式加热带的变形结构的结构示意图。
如图1、图2、图3、图4、图5和图6所示，座椅安全带加热组件包括安全带带体3和安全带加热机构。
可选地，安全带带体3的两端分别与卷收器1和固定件5连接，且安全带带体3上滑动设置有锁扣7。安全带加热机构包括加热控制组件和加热机构4，加热机构4固定于安全带带体3内部，加热机构4配置成加热安全带带体3。其中，加热机构4也可以称作加热组件。
请参阅图3，可选地，安全带带体3包括两个夹层301，加热机构4被夹持在安全带带体3的两个夹层301之间，两个夹层301在安全带带体3的延伸方向的两端均固定连接，使得在安全带带体3的延伸方向上没有加热机构4暴露出来。而在安全带带体3的宽度方向上，加热机构4未凸出安全带带体3的宽度方向的两侧，也即加热机构4在安全带带体3的宽度方向上也未凸出安全带带体3，如此设计，既可以保证加热机构4的两侧能分别与安全带带体3的两个夹层301连接，提高连接牢固性，还可以避免出现加热机构4暴露在安全带带体3外，影响外观，降低乘客体验度的问题。
请参阅图4，本公开中，可选地，安全带带体3为扁平中空式结构的一体式织带，相较于折叠缝纫的安全带带体，本实施例涉及的安全带带体3的内部 具有容纳加热机构4的腔室，也即安全带带体3内置加热机构4，使得加热机构4不外露在安全带带体3表面，更美观；使用时，用户直接与安全带带体3接触，而不易与加热机构4直接接触，使得安全带带体3的触感更舒适。
请继续参阅图4，加热机构4的一侧与安全带带体3固定连接，应当理解，加热机构4还可以是相对的两侧均与安全带带体3固定连接，从而提高连接结构的强度。
可选地，加热机构4在使用状态下一端止于固定件5前端的安全带带体3上，另一端止于卷收器1前端的安全带带体3上。需要说明的是，本实施例的加热机构4的使用状态指的是，乘客坐上座椅之后佩戴上安全带带体3时的状态，即滑动设置于安全带带体3上的锁扣7插入锁套9的状态，此时安全带带体3被拉出卷收器1的长度增加，在拉动安全带带体3的过程中，加热机构4从卷收器1中随安全带带体3一起被拉出，也即加热机构4位于卷收器1的外侧，使得加热时不会对卷收器1产生影响。应当理解，卷收器1和固定件5可以固定在座椅主体11上，也可以固定在车身上。
换句话说，加热机构4在安全带带体3的延伸方向上的长度尺寸小于安全带带体3的长度尺寸，加热机构4的耗材少，节省成本。
请参阅图5，可选地，加热机构4为电阻式加热带401，电阻式加热带401包括加热区40、隔离区50和回路连接区60。具体的，电阻式加热带401还包括有第一电极91和第二电极92，隔离区50将加热区40分割为第一加热区41和第二加热区42，第一加热区41的导体经线71连接第一电极91，第二加热区42的导体经线71连接第二电极92，第一电极91和第二电极92均为取电端，可选地，在第一电机91和第二电机92的端部集成插头，该插头配置成与带电的插座插接配合，便于取电。
可选地，电阻式加热带401的隔离区50与安全带带体3的上下两侧带体采用缝接、焊接或粘接三者中的至少一种方式约束固定在一起。需要说明的是，安全带带体3的上下两侧为安全带带体3的厚度方向的两侧，换句话说，安全带带体3为扁平状，安全带带体3的厚度方向为垂直于安全带带体3的配置成与人体接触的带面的方向，安全带带体3具有两个带面，一个带面配置成与人体接触，另一个带面背离人体。
本实施例中，电阻式加热带401与安全带带体3固定连接，当乘用者拉拽安全带带体3时，或者拉动锁扣7使锁扣7在安全带带体3上滑动时，作用力直接作用在安全带带体3上，当电阻式加热带401只有隔离区50与安全带带体3固定在一起时，隔离区50随着安全带带体3的受力形变而形变，而因导体经线71的加热区40与安全带带体3并未固定，故变形力传递到加热区40已经被衰减，有助于保护导体经线71，从而有助于延长电阻式加热带401的使用寿命。
可选地，安全带带体3与隔离区50之间采用整体式、分段式或点状间隔式固定连接，隔离区50和安全带带体3固定在一起，使得第一电极91和第二电极92始终保持具有间距的位置关系，且第一电极91和第二电极92被安全带带体3包裹，安全带带体3为绝缘材料制成，可防止第一电极91和第二电极92出现短路的情况。此外，第一电极91和第二电极92外均可以设置绝缘保护层，防短路效果更好。
应当理解，隔离区50可以和安全带带体3建立约束关系，加热区40也可以与安全带带体3建立约束关系。电阻式加热带401的外侧也设置有隔离区50。隔离区50与安全带带体3上下两侧的带体均固定在一起，使得与第一电极91和第二电极92对应于连接的导体经线71完全隔离开，无法接触，防止第一电极91和第二电极92的电路短路。
换句话说，本公开的电阻式加热带401与安全带带体3连接时，电阻式加热带401的中部以及两侧均具有一个隔离区50，通过三个隔离区50同时将电阻式加热带401固定于安全带带体3上，固定效果好。
可选地，电阻式加热带401由经线和纬线编织而成，加热区40的经线包括间隔交替布置的导体经线71和绝缘经线72，导体经线71可作为电阻式加热带401的加热体，加热区40的绝缘经线72将相邻的导体经线71分隔开，避免相互接触而短路；隔离区50采用绝缘经线72和绝缘纬线81编织而成，电阻式加热带401一端的回路连接区60的纬线包括导体纬线82和绝缘纬线81，导体纬线82和绝缘纬线81可以交替排布。需要说明的是，上述经线的交替布置不一定只表示一根导体经线71和一根绝缘经线72交替排布，相邻导体经线71之间可以有若干绝缘导线72。
需要说明的是，本公开中，导体经线71和绝缘72沿安全带带体3的宽度方向交替排布；导体纬线82和绝缘纬线81沿安全带带体3的长度方向交替排布。
可选地，隔离区50的宽度为5mm-35mm，从而可防止汗液和电解质饮料等污染造成的第一电极91和第二电极92短路。其中，绝缘区50的宽度方向与安全带带体3的宽度方向保持一致。
例如，绝缘区50的宽度可以是5mm、20mm或35mm等，本公开中不进行一一列举，按需设置即可。
可选地，导体经线71和导体纬线82的材质均为金属线、碳纤维、复合镀层纤维或者由金属线和非金属线组成的复绕线等；绝缘经线72和绝缘纬线81的材质均为尼龙线、涤纶线、棉线、芳纶或者是人造丝等。
可选地，加热控制组件包括电子控制器、安全带加热开关、锁扣开关8和座椅占用探测机构，电子控制器、安全带加热开关、锁扣开关8、座椅占用 探测机构和加热机构4依次串联。即座椅上坐人且在安全带带体3上的锁扣7插入锁套后，再打开安全带加热开关，加热机构4才被通电，加热机构4才可以对安全带带体3进行加热，从而避免在无人乘坐但是在锁扣7插入锁套后，加热机构4就会启动进入加热状态产生的热能浪费。且电子控制器还可同时控制座椅加热，即电子控制器与固定于座椅上的座椅加热垫12相连，且座椅加热垫12也经安全带加热开关控制，从而可经加热控制组件同时控制安全带带体3和座椅加热垫12同时进入加热状态，操作方便。
可选的，电子加热器可以是ECU加热控制器。
此外，加热控制组件也可以称作控制组件。座椅占用探测机构也可以称作座椅占用传感器。
换句话说，当乘客乘坐于对应的座位上后，对应座位上的座椅占用探测机构检测到乘客，座椅占用探测机构被激活；并且，位于座位上的乘客将该座位上的锁扣7插入对应的锁套9后，锁扣开关8被激活，此时，再打开安全带加热开关，加热机构4通电后工作，为安全带带体3加热。
可选地，位于第一加热区41靠近固定件5的一端的导体经线71以及位于第二加热区42靠近固定件5的一端的导体经线71分别与第一电极91和第二电极92连接。第一电极91和第二电极92均可以是带绝缘外衣的金属导线，也可以是其他可以导线的零部件。例如，第一电极91和第二电极92均为电阻式加热带401的取电端，即当第一电极91和第二电极92为金属导线时，可以连接端子护套，通过端子护套与电源连接；第一加热区41另一端的导体经线71与第二加热区42另一端的导体经线71经回路连接区60连接，且每个电极设置有至少两根导体经线71，进而能通过改变导体经线71的阻值、长度或者数量三个中的至少一个参数调节整个电阻式加热带401阻值的大小，从而调节加热温度。
需要说明的是，本实施例设置的座椅可以作为前排座椅(第一排座椅)，也可用于第二排以及之后的座椅，且本实施例的安全带为三点式安全带。还需要说明的是，座椅安全带加热组件和卷收器1可以固定在座椅主体11上，也可以固定在车身上。
因此，本发明采用上述实施例的座椅安全带加热组件，通过将加热机构4设置在扁平中空式结构的安全带带体3的内部，加热机构4不会裸露在外，安全系数更高，触感更好，也更为美观。
本实施例还提供了一种座椅，该座椅包括上述的座椅安全带加热组件。座椅的结构和工作原理的描述如下：
图7为本发明的实施例提供的一种座椅的结构示意图；图8为本发明的实施例提供的一种座椅的使用状态图；图9为本发明的实施例提供的一种座椅的 安全带带体的横截面图。
如图7-图9所示，本发明的座椅包括座椅主体11、靠背10和座椅安全带加热组件，靠背10和座椅主体11连接，座椅安全带加热组件可以固定在座椅主体11上，也可以固定在车身上。
可选的，座椅主体11上固定有固定件5和在使用安全带带体3时插接锁扣7的锁套9。
座椅安全带加热组件包括安全带带体3、加热机构4和控制组件。加热机构4与安全带带体3连接，配置成加热安全带带体3，控制组件与加热机构4通信连接，配置成开启或关闭加热机构4。
本公开中，安全带带体3的两端分别与卷收器1和固定件5连接，且安全带带体3上滑动设置有锁扣7；具体的，靠背10的后侧设有导向器2，安全带带体3绕过导向器2的一端滑动设置有锁扣7。
请参阅图2，控制组件13包括ECU加热控制器131、安全带加热开关和配置成检测锁扣7是否插入锁套9的插入检测单元134，可选地，插入检测单元134为置于锁套9内部的锁扣开关8。显然，插入检测单元134还可以包括配置成监测锁扣开关8开闭状态的传感器，如电容传感器或者图像式传感器。可选地，安全带加热开关、插入检测单元134和加热机构4均与ECU加热控制器131串联，且使ECU加热控制器131与安全带加热开关、插入检测单元134和加热机构4建立电连接关系，实现当ECU加热控制器131检测到安全带加热开关为加热状态时，且当经插入检测单元134探测到锁扣7插入锁套9内时，ECU加热控制器131控制加热机构4开始加热。
由上述可知，加热机构4的加热功能是否启动受到锁扣7是否插入锁套9和安全带加热开关是否处于加热状态的双重限制，也就是说，安全带加热开关和锁扣开关8为“与”状态，即使启动了安全带加热开关进入加热模态，也只有当安全带带体3上的锁扣7插入锁套9后，ECU加热控制器131接收到安全带带体3的锁扣7插入信号(常规状态下锁扣7未插入锁套9，此时锁扣开关8处于常闭状态，插入锁扣7后，锁扣开关8断开，并将此变化状态传送至ECU加热控制器131)，ECU加热控制器131给加热机构4通电，方可进行加热工作。如此设计，可以避免不使用安全带带体3或不需要对安全带带体3加热时，加热机构4启动对安全带带体3进行加热，造成能源的浪费的情况。
可选地，安全带带体3靠近固定件5的一端设置有引出导线，引出导线一端与加热机构4相连，另一端形成引出电极6。本实施例的引出电极6配置成与供电接口电连。可选地，安全带带体3包括至少两根与加热机构4电连接的引出导线，进而可通过改变引出导线的数量来改变其阻值的大小，从而调节加热机构4输出的加热温度。
例如，引出电极6可以为两根，两根引出电极6可以分别为第一电极91和第二电极92。
本公开中，可选的，控制组件13还包括感温单元135，其设置在固定件5前端的安全带带体3内。感温单元135为热敏电阻或者双金属温度传感器，感温单元135与ECU加热控制器131相连，通过感温单元135检测到安全带带体3的实时温度并反馈至ECU加热控制器131，然后利用ECU加热控制器131控制加热温度，温度调控更加准确，满足不同乘客对于温度的需求，乘客体验度高。例如当环境温度为10℃时，预热3分钟后自动关闭加热功能；当环境温度为0℃时，预热5分钟后自动关闭加热功能；或者ECU加热控制器131内部搭载有配置成记录加热机构4加热时间的计时程序，即ECU加热控制器131还通过计时控制加热，累计计时5秒至10分钟，此时安全带加热器和座椅加热器累计了一定热量，ECU加热控制器131自动关闭加热功能。
本公开中，可选的，请参阅图9，安全带带体3设为一体型扁平中空式结构，且安全带带体3内置有加热机构4；安全带带体3的内壁的至少一侧与加热机构4固定连接。可选地，安全带带体3与加热机构4可以采用缝接、粘接、铆接或高频熔接实现固定连接。
例如，安全带带体3的内壁在其厚度方向上具有相对的两侧，加热机构4设于安全带带体3的相对的两侧之间，加热机构4同时与安全带带体3的内壁的相对的两侧固定连接，连接强度高，结构牢固可靠。
可选地，加热机构4为电阻式加热带401，电阻式加热带401包括基体层和夹接于基体层内部或者粘接于基体层外部的加热层。且基体层的材质为无纺布、网纱、合成皮革、革、泡沫垫、塑胶薄膜、高弹海绵、EPDM和PVC中的至少一种；加热层为曲折布置的电阻丝或者为由电阻线和绝缘丝编织而成的加热垫。
可选地，加热机构4分段或者连续布置于安全带带体3上。相比于传统的固定方式，电阻丝粘接效率更高。
本公开中，可选地，座椅还包括座椅加热装置。
座椅加热装置包括座椅加热垫12和座椅加热开关，座椅加热垫12设置于座椅主体11上，配置成为座椅主体11加热，从而为乘坐于座椅主体11上的乘客加热，避免座椅主体11温度过低，影响乘坐舒适性。
座椅加热开关与安全带加热开关串联或者并联。串联和并联可实现两种不同的控制方式。可选地，座椅加热开关和安全带加热开关还可集成为一个开关，以下对安全带加热开关和座椅加热开关的三中连接方式进行分别说明：
当座椅加热开关与安全带加热开关串联时，座椅加热开关和安全带加热开 关为“与”的状态，需同时打开座椅加热开关和安全带加热开关，座椅加热垫12和加热机构4才会进入加热状态，即实现座椅主体11加热和安全带带体3加热的同时控制，且此时座椅加热开关和安全带加热开关共用一个控制器控制，如，座椅加热开关和安全带加热开关均与ECU加热控制器131电连接。
当座椅加热开关与安全带加热开关并联时，座椅加热开关和安全带加热开关为“或”的状态，即可经座椅加热开关和安全带加热开关分别控制座椅加热垫12和加热机构4的工作状态，且此时座椅加热开关和安全带加热开关经两个控制电路分别控制，即实现座椅主体11加热和安全带加热的单独控制。显然，座椅加热开关和安全带加热开关可以均集成在ECU加热控制器131上，采用两个独立的控制电路即可。
座椅加热开关和安全带加热开关共用一个开关，此时座椅主体11加热和安全带带体3加热共用一个控制器控制，从而实现同时启动和同时关闭。需要说明的是，座椅加热开关和安全带加热开关可以为设于ECU加热控制器131上的一个集成开关。
本公开中，可选地，座椅主体11上安装有座椅占用探测机构133，座椅占用探测机构133与ECU加热控制器131通信连接。本实施例中，座椅占用探测机构133可以为安装在座椅加热垫12区域内的薄膜式开关、机械式开关或者电容式开关等。可选地，座椅占用探测机构133、座椅加热开关和安全带加热开关串联设置，实现在座椅占用探测机构133检测到座椅主体11上乘坐有乘客且需同时打开座椅加热开关和安全带加热开关，座椅加热垫12和安全带带体3加热才会同时进入加热状态的功能，从而避免在无人乘坐但是在锁扣7插入锁套9后，加热机构4就会启动进入加热状态产生的热能浪费。
需要说明的是，本实施例设置的座椅可以作为前排座椅(第一排座椅)，也可作为第二排以及之后的座椅，且本实施例的安全带为三点式安全带。
因此，本发明采用上述结构的座椅，闭合安全带加热开关，且将安全带带体3的锁扣7插入锁套9，ECU加热控制器131控制加热机构接通电源，开始加热，从而提高用户的舒适度。
最后应说明的是：以上实施例仅用以说明本发明的技术方案而非对其进行限制，尽管参照较佳实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对本发明的技术方案进行修改或者等同替换，而这些修改或者等同替换亦不能使修改后的技术方案脱离本发明技术方案的精神和范围。
