Description

表皮部件
技术领域
本发明涉及一种以粘贴在基材上的方式使用的表皮部件。
背景技术
以往,在汽车的仪表板等内装部件中,有一种在合成树脂制的基材上粘贴皮革等表皮部件的内装部件。有时表皮部件将多个基布的末端部相互进行一次缝制来接合,并展开该缝制边,进一步进行二次缝制而缝制到基布的基材一侧的面,由此形成针脚状的图案以提高美观性。
在为一次缝制配置成圆弧状等曲线状的结构的情况下,在其内周侧的基布的缝制边上产生余料而成为拱起的状态。在该情况下,即便在基材上粘贴表皮部件,拱起的缝制边也无法紧贴在基材上而依旧成为拱起的状态,因此不美观。
在这种情况下,通常已知有一种方法,将内周侧的布的端缘切开成锯齿形状来形成花齿部,由此减少多余的布以解决拱起(例如,参考专利文献1。)。
专利文献1:日本特开2000-54210号公报(第2页、图1)
然而,在为基材上粘贴表皮部件的结构的情况下,花齿部的锯齿形部分的顶端很尖,因此在基布为皮革等硬质的材料的情况下,锯齿形部分的顶端上推粘贴在基材上的表皮部件的基布,致使图案面上产生锯齿形状的皱纹,而有可能导致美观性下降。
发明内容
本发明是鉴于这种问题而完成的,其目的在于提供一种提高粘贴在基材上的状态下的美观性的表皮部件。
技术方案1所述的表皮部件,其以粘贴在基材上的方式使用,所述表皮部件具备:多个基布;第一接合部,接合所述多个基布的末端部,且该第一接合部的至少一部分配置成曲线状;第二接合部,将各所述基布的末端部的通过所述第一接合部而形成的接合边分别接合到各所述基布的所述基材一侧的面;以及花齿部,该花齿部是在如下的端缘切开形成为锯齿形状而成的,所述端缘是所述基布中所述第一接合部的曲率大的一侧的所述接合边的端缘,所述花齿部中,至少锯齿形的顶端部形成为曲线状。
技术方案2所述的表皮部件,其在技术方案1所述的表皮部件中,花齿部形成为曲线状。
发明效果
根据技术方案1所述的表皮部件,第一接合部的曲率大的一侧的基布的接合边的端缘的多余部分因花齿部而减少,因此即使第一接合部中至少一部分配置成曲线状,接合边也不会拱起,而能够以将基布紧贴在基材上的状态粘贴,并且由于花齿部的锯齿形的顶端部形成为曲线状,因此不易因花齿部的形状而从基材侧上推基布,也不易在图案侧产生锯齿形状的微细凹凸,因此能够提高将表皮部件粘贴在基材上的状态下的美观性。
根据技术方案2所述的表皮部件,除了技术方案1所述的表皮部件的效果之外,更不易因花齿部的形状而从基材侧上推基布,从而能够进一步提高将表皮部件粘贴在基材上的状态下的美观性。

附图标记说明
11-基材,12-表皮部件,18-基布,20-作为第一接合部的一次缝制部,21-作为接合边的缝制边,22-作为第二接合部的二次缝制部,25-花齿部,25a、25b-顶端部。
具体实施方式
以下,参考附图对本发明的一实施方式进行说明。
图3中,10为内装部件。内装部件10例如使用于汽车的车内。内装部件10为例如使用于汽车的仪表板、外装饰件、气囊盖板等中的车辆用内装部件。
内装部件10以在基材11上粘贴表皮部件12的方式构成。
基材11通过合成树脂等部件而形成。基材11具备具有规定面积的覆盖面部15。
表皮部件12以覆盖覆盖面部15的方式配置。表皮部件(12)具备多个基布(18)。作为基布18,例如使用天然皮革、合成皮革等皮革或布等。就这些基布18而言,其末端部通过作为第一接合部的一次缝制部20缝制而被接合,并且作为接合边的缝制边21重叠在基布18的基材11侧(覆盖面部15侧)的主面即背面侧,并通过作为第二接合部的二次缝制部22分别缝制而被接合。
在本实施方式中,如图1及图2所示,以设定有一个基布18a及另一个基布18b这一对的基布18进行说明,但基布18的片数并无限定。
一次缝制部20用来接合基布18彼此。一次缝制部20中至少一部分在沿覆盖面部15(图3)的面配置成曲线状。即,一次缝制部20中至少一部分向与其延伸方向交叉的方向弯曲。在本实施方式中,一次缝制部20中至少一部分呈圆弧状。在图示的例子中,一次缝制部20配置成曲率半径110mm以下的圆弧状。在本实施方式中,为了清楚地说明,仅对如图2所示一个基布18a成为一次缝制部20的曲率小的一侧(曲率半径大的一侧)即外周侧,而另一个基布18b成为一次缝制部20的曲率大的一侧(曲率半径小的一侧)即内周侧的部分进行说明,但例如在一次缝制部20形成为波状的情况等下,一个基布18a与另一个基布18b的曲率大小根据一次缝制部20的弯曲方向发生改变,并非有意限定为在一个基布18a与另一个基布18b中某一个固定为大曲率侧而另一个固定为小曲率侧的结构。
二次缝制部22用来在图案面上构成针脚状的图案。二次缝制部22相对于一次缝制部20,隔开恒定或大致恒定的间隔靠缝制边21的端缘分开。即,在一次缝制部20为曲线状的情况下,二次缝制部22也配置成相同的曲线状。如图1所示,在本实施方式中,相比一次缝制部20的针脚的间距P1,二次缝制部22的针脚的间距P2设定得更大。
在图2所示的例子中,二次缝制部22在本实施方式中设定有将一个缝制边21a接合到一个基布18a的一个二次缝制部22a及将另一个缝制边21b接合到另一个基布18b的另一个二次缝制部22b。
而且,在基布18中一次缝制部20的曲率大的一侧的缝制边21的端缘切开形成有锯齿状的花齿部25。在图示的例子中,花齿部25形成于另一个基布18b的另一个缝制边21b的端缘。
花齿部25将缝制边21的端缘切开形成为锯齿形状。而且,花齿部25中至少锯齿形的一个折回部即作为凸顶点的顶端部25a与锯齿形的另一个折回部即作为凹顶点的顶端部25b分别形成为曲线状,呈不具有尖部或角部的形状。在本实施方式中,花齿部25的顶端部25a、25b形成为圆弧状。并且,在图示的例子中,花齿部25形成为整体相连的曲线状,呈圆弧交替相连的波状。
花齿部25的锯齿形的顶端部25a、25b的圆弧形状可以彼此相同,也可以互不相同。如图1所示,花齿部25的锯齿形的顶端部25a、25b的曲率半径R1、R2优选设为0.6mm以上。在本实施方式中,曲率半径R1、R2分别被设定为0.6mm。
并且,花齿部25的锯齿形的间距a被设定为花齿部25的锯齿形不会进入缝制一次缝制部20时使用的针车夹具中。在本实施方式中,间距a例如被设定为1.5mm。
而且,作为花齿部25的锯齿形的凹顶点的顶端部25b与二次缝制部22的距离b被设定为二次缝制部22不落入花齿部25的锯齿形。在本实施方式中,距离b例如被设定为1.5mm。
并且,在本实施方式中,二次缝制部22与一次缝制部20的距离c被设定为一次缝制部20与作为花齿部25的凸顶点的顶端部25a的距离d的一半以上。
在图示的例子中,距离c例如被设定为4.0mm,距离d例如被设定为7.0mm。
另外,这些数值并非固定,可以根据基布18的种类或一次缝制部20的曲率及缝制时使用的针车夹具的形状来设定。
而且,在形成表皮部件12时,首先将基布18a、18b的末端部中图案侧的主面彼此重叠并通过一次缝制部20来缝合。
接着,将因一次缝制部20的缝合而产生的缝制边21a、21b以一次缝制部20为基准左右展开并重叠在基布18a、18b上,并通过二次缝制部22将这些缝制边21a、21b缝合到基布18a、18b上。
花齿部25优选在通过一次缝制部20进行缝合之前预先形成于另一个基布18b的端缘上,但既可以在通过一次缝制部20进行缝合之后形成,也可以在通过二次缝制部22进行缝合之后形成。
如此形成的表皮部件12,由于花齿部25,一次缝制部20的内周侧中另一个基布18b的另一个缝合边21b的端缘的剩余部分减少,因此即使一次缝制部20配置成曲线状,另一个缝合边21b也不会拱起,而能够以将另一个基布18b紧贴在基材11的覆盖面部15的状态粘贴,并且花齿部25的锯齿形的顶端部25a、25b形成为曲线状,在本实施方式中形成为圆弧状,而不具有尖部或角部,因此不易因花齿部25的形状而从基材11侧上推另一个基布18b。因此,另一个基布18b即便为硬质的材料,也不易在图案侧产生锯齿形状的微细凹凸。因此,能够提高将表皮部件12粘贴在基材11上的状态下的美观性。
并且,将花齿部25的锯齿形设为曲线状,由此更不易因花齿部25的形状而从基材11侧上推另一个基布18b,从而能够进一步提高将表皮部件12粘贴在基材11上的状态下的美观性。
另外,在上述一实施方式中,花齿部25的顶端部25a、25b各自并不限于圆弧状,例如也可以呈椭圆曲线状、二次曲线状、正弦波状或余弦波状等任意的曲线状。
并且,各接合部并不限于缝制,也可以采用任意的接合方式。
产业上的可利用性
本发明例如适合用作汽车的内装部件的表皮部件。
